Hank you. Thank you. Thank you so much, Michael for this very nice introduction, and thank you so much for inviting me. I'm delighted to be here. So, as Michael mentioned, this project is really about thinking about the employment impacts of the green transition, but from the standpoint of green innovation impacts on employment outcomes. So, this is joint work with my colleague Msatoz, also assistant professor LC in the same department, and Francesco Va, from the University of Milan. Um, this is very much an ongoing project. Some of the results that I will present to you today are fairly preminary, so please keep that in mind, and I really welcome your feedback as we go to inform this project. So, our starting point here is the broader question of how technological transitions affect employment outcomes and environmental outcomes. So there's quite a bit of research already about the impact of automation innovation, unemployment impacts, particularly as it pertains to the impact on displacement of labor, with lower skilled workers being displaced by automation innovation, and also on its effect on wage growth, with depressing effect on wage growth. And also the it tends to polarize the job market with a lot of new jobs creation through automation going to high skilled workers and low skilled workers benefiting less from that type of innovation. But there's less analysis on the impact of that type of innovation on green innovation. Environmental outcomes and particularly on greenhouse gas emissions reduction. So that's one of the things we're going to look at here. And the two main types of technological transition we're going to look at is the two arguably main ones that we're going through globally. First, of course, decarbonization. I won't have to motivate the need for that to this audience, I'm sure, where we see across the developed world, large and emerging world, large green investments to decarbonize our economies. And one ways they are build and sold to the public is as massive creators of employment. And usually, these are portrayed as new jobs that would be relatively high skilled, so quality jobs, that would be relatively well paid, and that would be numerous. So one of the things that this project is trying to tackle is whether we can expect that to be the case, really. And the other thing that's interesting to us is whether this push for greater automation that we see both through development in AI and broader digitalization of the economy can have any synergies with green innovation, and whether it can actually help hasten the reduction of emissions or conversely slow it down and act as a detriment to it. So this kind of idea of a twin digital and green transition happening at the same time in our economies. So just to make a bit more concrete, what do we mean by interactions between the two, here are two very recent examples, pull out from the press. On an example here on the left hand side of a solar panel, well, solar power plant manufacturing company really, that is developing a robot to make the deployment of solar panels into power plants both faster and cheaper. That's an example where automation will actually help decarbonization by make it more accessible from a cost standpoint, And here on the right hand side, an example of the use of modern machine learning techniques here to help make the grid more reliable and more amenable to higher rate of penetration of renewables. Because as you know, when you have higher rates of penetration of renewable energy production, that can make the grid unstable. And here, this companies develop is using tools developed in the machine learning world to help stabilize the grid. So again, another example where you can have positive synergies between the digital transition and the grid transition. So in terms of the expected employment impacts of the green transition. It's not just used as kind of a crutch by policymakers to sell it to the public. It's also expected by decision makers in the private sector to be a big source of new jobs. So here, this is a survey conducted annually by the World Economic Forum on a panel of international representative decision makers in the private sector, and they asked them about a number, maybe a bit small to see. But essentially, they asked them to rank a number of global trends going on. So here you have green transitions, you have broadening digital access, you have the COVID pandemic, increased geopolitical tensions. So all the main trends and asked them whether they thought that it would be mostly a source of job creation or mostly a source of job destruction. And you consider the ones that consistently ranked the highest are the green trends. So again, there's this really broad expectation that the green transition will be a net source of job creation, but we lack empirical evidence for that, and that's what we're trying to address here. Another example of that is, of course, the US IRA, which was presented to the public, mainly as a investment plan in reindustrializing America and as a big source of potential job creation. So this is an evaluation run by the LEP that projected that 1.5 million jobs could be created by the IRA. But again, that's predicated on the idea that renovation will not be a net job destructor, and that would not act as automation, for which we do not have empirical evidence, which is what we're trying to remedy. So that brings me to the research question we're trying to address here. The first one is, will emerging technologies like automation and green innovation be a source of job creation or job destruction? Well the compliment workers or substitute for workers. Second, trying to better understand how innovations in green technologies are diffusing through the economy. That's one really challenging thing to do, trying to find reliable empirical measures of technological adoption at the firm level, and that's something we're trying to address. Third, how does exposure to green innovation. So if you are a firm that adopts green technology, what does that mean for your outcomes in terms of employment? In terms of the types of people you're going to recruit, in terms of the type of wages you're going to provide, and in terms of environmental outcome. So dos adoption of green innovation lead to enhanced emissions reduction in particular. And finally, whether there's a tension between being an adopter of green and digital innovation. So the idea here is that adopting digital innovation, adopting automation driven innovation is meant to enhance the firm's productivity. So that actually run counter to the objective of decarbonization. If the improvements you experience in productivity are going faster than how fast you can decarbonize. So we want to address whether we actually see any evidence for that in our empirical analysis. So the contributions were trying to make here is first, we contribute a novel measure of technological adoption at the firm level. So here the idea is that we're going to observe the content, the occupational content at the firm level through the job vacancies they post. So essentially, the idea is that when a firm wants to recruit someone, it describes the occupational content of the position. And that description contains the type of skills that they expect the person to have to fill the position. And those skill requirements actually gives us information about the type of production process and the type of technologies that the firm uses. That's really like the kernel of The core idea of our measure. And then we also contribute what we believe to be the first link between occupational skills and patents. So to link innovation with the occupational content of work. Second, we try to answer the question of whether g innovation is labor augmenting, meaning whether it act as a compliment for worker, enhancing their capabilities and potentially acting as a net positive for employment, or whether it's labor saving, which is acting as a substitute for workers and acting as replacement for workers thereby having a negative impact on employment. T hird, we conduct a causal impact assessment. So here, causal understood in econometrics term of what being an adopter of green and automation innovation at the firm level means for the firm level outcomes, both in terms of employment and in environmental terms measured by firm level emissions. And finally, y, we compliment that with the environmental aspect of things through greenhouse gas emissions observed at the establishment level. So I know that like some of you will need to leave at 1:00 P.M. So I'll skip the literature in the interest of time. We feel that we try to contribute to four mainstreams of the literature, just to go over them quickly to the employment impacts of the green transition, quite obviously. We also contribute to how technical change affects skills requirements and employment impacts. So the broader literature on technological transition and employment. We also contribute this new measure of firms exposure to innovation and technological adoption. And finally, to this very new and emerging literature on how this idea of twin transition between the digital and green transition interacts and may deliver benefits for the green transition itself. So again, knowing that some of you will have to live in half an hour, here's a preview of our results. So what we find is that the expected impact of green innovation on labor outcome is highly heterogeneous. We find that some green technologies are expected to be labor augmenting and actually as labor augmenting as the most labor augmented technologies we observe outside the world of green innovation. And other green innovation actually at the opposite end of the spectrum, as as labor saving as technologies we observe elsewhere in the economy. So to give example, we find that innovations to decarbonized information and communication technologies or to green buildings are quite labor augmenting, and I'll explain that in a minute in a couple of slides. But conversely, innovations in green transportation, particularly in EVs, or in Smart grades are quite labor saving, and thus expected to have quite detrimental impacts on employment. We also find that looking at a dynamic perspective, so we'll be able in our sample to go all the way back to the 80s. And so over this like four decade time span from the 80s to 2020, we find that green innovation has become increasingly less labor augmenting over time, which again, I will explain in a minute. We also have some more primary results, p empirical analysis at the establishment level. We find that establishments that are early adopters of green technologies tend to create more jobs when looking at it at a decadal time span. Essentially, we look at whether you're an early adopter of green technology in the early 2010, and we look at your employment outcomes in the early 2020s. And what we find is that the more green technology we're adopting, the more jobs you're creating. Now, looking at the nature of those jobs, we find that just like automation before, reinnovation tends to be slightly skills biased, meaning that those jobs tend to be more prevalently high skilled jobs than low skilled jobs. But the extent to which that's the case is much lower than for automation. And finally, we don't find any evidence that being an adopter of automation prevents an establishment or a firm from reducing its emissions. So that's actually good news for kind of a green growth type of story, whereby you can still have productivity improvements from automation and yet still be able to reduce emissions in absolute terms. All right, so let's get into the details of this. So first, the conceptual framework we have in mind, driving this analysis. So as I was mentioning, we're considering two types of two categories of technological innovation, green innovation, and automation innovation. And we're going to look at their impact on a variety of dimensions, on labor, whether it's a net job creator or net job destroyer, on whether it biases job creations towards high skilled workers or not, and also environmental outcomes as measured by greenhouse gas emissions. And from the literature, we have some priors about these. So most of our priors are really for automation because, as I was saying, that's where most of the research has been happening so far. So we know that adopting automation innovation is probably going to lead to destructive effects on labor, to reduce the demand for labor. As a consequence, or sorry, simultaneously, even though in the aggregate it reduces the demand for labor, it increases the demand for high skill labors. It's quite scale biased towards high skilled workers. But the effect on emissions has not been explored so far, so that's something where we don't really have a strong prior and where we want to make a contribution. Conversely on green innovation, the one where we have a strong price that hopefully adopting green innovation or adopting green technology should make you better at reducing your emissions because that's the whole point of green technologies, obviously. In terms of its effect on labor, we don't really know whether it's labor augmenting or labor savings. That's the thing that we're trying to answer. And whether it's going to be skill biased, we do have evidence that green jobs that have been created so far tend to be overrepresented in the stem professions. So it might be skills biased towards high skilled workers, but again, until at least our project, we don't think that we had strong evidence for that. And in terms more generally on the impact of labor saving versus labor augmenting innovation. So this is a taxonomy to classify innovation that's been used in the labor literature, particularly to look at automation and AI that we borrow here. It's effect on labor, when it's labor saving by definition, it is destructive for jobs. And, in terms of wages, if you reduce demand for labor, that's going to depress wages, going to make workers less able to bargain for higher wages. Conversely, labor augmenting innovation tends to have a positive impact on labor, but the impact on wages can be ambiguous because it will depend on workers' ability to take advantage of those labor augmenting innovations. Remember, labor augmenting innovation is meant to act as a complement to workers' skills, so you still need to have the right skills to take advantage of those labor augmenting innovations. Okay. So at this point, we need two things really to answer our research questions. First, we need to develop that novel measure of technological adoption at the firm level. And then in a second step, we're going to need to answer that question of whether green innovation is labor augmenting or labor saving. So first, how are we going to go about measuring firm level technological adoption? So this is a broader challenge in the economics literature, as I was saying, observing which technologies are adopted within the firm is quite tricky because we don't have good information on that. And here, for our design to work or rather to answer our research question, we need even, like an establishment level. Adoption of technical production. So what I mean by establishment, think of it as a single manufacturing facility, a single manufacturing site, right? So a firm will be composed of multiple establishments in the general case spread out across the territory. So usually, one way to go about this is to use Peyton counts at the firm level, so to look at the firm, look at what innovation produces, what Peyton produces. Now, we don't believe that's really going to work here because particularly, I mean, that's the case for other technologies, too, but particularly in the case of green innovation, oftentimes you're adopting innovation that you haven't generated yourselves. T, for example, of the solar industry, most of the innovation today is happening in China, and yet you have firms adopting innovation produced by Chinese firms in the solar industry all across the world. So in those case, just looking at the firm's own patent counts is not going to cut it to really understand what technologies they're adopting. So here as I was mentioning earlier, our new measure is going to build upon observing the job positions, job postings that a firm offers to understand what is the scale content of its work. So the idea is that skills that firms are seeking in their job ads contain information on the content of the work that people are going to perform in that firm. That in turn will tell us something about the type of technological process they use in their production process. And so that's something that has already been explored in the case of AI, particularly with this year's Nobel Prize winner in Economics, Darn Moglu. David Alto also at MIT, has very recent and brilliant work on that topic. So we kind of adapt that to the green innovation context. And to do that, we'll need some way to link patents that are going to be our measure of innovation still and occupational skills, which is where we get the firm level observation of whether the technologies are being adopted. So, what dataset are we're going to use? First, a dataset on job postings. So we take advantage of a dataset from a company called LCAst. If there's economists among you might have heard of it as the Burning Glass Dataset. It changed name recently. So essentially, it's a company that's been collecting scraping, for lack of a better word, really, online data from the universe of online sources for job postings in the US, more than 50,000 in just the case of the US, since the late ts, our data set here is going to start in 2010. And what they provide in terms of guarantees that first, we have the universe of all online job ads in the entire United States. And second, it provides structure on that raw textual data. What I mean by structure is that first, it cleans it and de duplicates it, which is already like a massive benefits. We have the guarantee that each job ad we observe correspond to exactly one position open at a particular firm. Second, it's going to extract structured data from the raw textural description. The way we're going to observe the scale content of a particular position is not as unstructured natural language text, but as a vector of skies. Right? And so those skills, they come from a taxonomy that LCs has constructed that is meant to represent that universe of online job ads. So 32,000 unique skills that are grouped in a hierarchical structure, and that provide us with information on that skill content. So I'm saying linking skills with innovation, skills with patents. That's the taxonomy of skills I'm referring to. And we also observe other the dimension of the job posting offered, particular, it's occupational category. So here, we use something from the Bureau of Labor Statistics called the standard occupational classification, the SOC, which is a standard classification of the whole labor force into 700 distinct occupations. We know the wage that is being offered. We know the educational requirements. The wage unfortunately has fairly low coverage because a lot of positions are being advertised without a wage range being reported directly publicly. So we roughly have wage in 25% of ads only. We also know the company name with really high coverage in 80% of cases, we know the name of the company that's offering the position. And we also know the location of the company of the sorry, the company of the job, which is actually very useful. That's how we're going to define an establishment. So there's going to be a combination of a job offered in a particular location by a particular firm. And here the location, we observe it at the county level, at least, in some cases, we observe it more precisely, but for our purposes, county level is sufficient, because the pyramiter that makes sense when you're looking at labor outcomes is something called the commuting zone in the US, which is essentially the size of a local labor market. So here establishment is going to be the interaction of a company in a commuting zone. Some limitations about that dataset. Obviously, because it's an online job ad dataset, some occupations in the high scale occupations can be over represented. Although this has gotten better over time as a growing portion of the labor market is going online. So here you can see on the left hand side, I dark blue, it's the share of a particular occupation in the light Cart dataset. And in light blue, the share in employment in the actual labor force in the US, right? And that's the average 2010-2024 that we use here. So you see, for some occupations, we're very close to being representative of the actual labor force. For others, when we try to have like nationally aggregated statistics, we'll need to re weight them by labor force weights. Another thing is that because we're seeing the flow of new positions, growing firms are going to be over represented like construction. So that means that, for example, for businesses or industries that are not expanding, like coal mining, if you're thinking about energy transition issues, they're going to be underrepresented in that. One thing to note, though, despite those caveats is that the dataset is so large, you're looking at 330 million job ads 2010-2024, that even for occupations that are underrepresented, we still have a lot of observation, we still have quite statistical power to conduct analysis. Finally, one thing to really keep in mind is that we only observe the demand side of the labor market. We do not know whether those positions were filled, and when they were filled, we do not know if the position corresponded exactly to what was being advertised by the firm. So that's a limitation of that approach that we recognize. But it's also still the most granular observation you can get with the current available datasets of the skies content at a firm level. So that's for the Labor side. Now for the Payton side, we use Google's Payton's public dataset. So it has two components. One is a worldwide bibiographic dataset on Peytons that has global coverage and goes the way back to the 19th century. And then it also has the whole US PTO, US patents and trademark office, data set for all patents text, title and abstract. So here we're going to limit ourselves to title and abstract, and we also observe the classification code of those patents. So Patents have multiple different categorization. One that is used internationally is the cooperative patent classification or CPC classification. It's a hierarchical taxonomy that helps tag which technologies particular patent relates to. Single patent generally will have multiple CPC codes. I'll get to in a minute to how we use that in our context. So one thing is that a lot of patents are actually not necessarily like high quality patents, by which I mean, most patents never get a single citation, for example. So to restrict our datasets to quality patents, we define a certain quality threshold for it to be included in our dataset. So first, we require that received at least one citation. And second, we look at where that patent was filed. So in general, the patent is going going to be filed in one country. But if a patent is particularly important, the inventor or the company filing it will tend to file it in multiple locations. And there's one particular case where a patent is filed in the three main patent offices in the world. The European patent office, the Japanese patent office, and the USPTO. And those patents are called triadic patents, because they're find those three locations. And this is usually in the literature used as like the definition of like high quality patents because it takes time and resources to find in those three of these locations. If the patent was worth paying that cost, there's probably a good indication it was a high quality patents. So once we rest we apply that restriction, we're left with 1.6 million patents 1980-2019. And that's the corpus of texts of patent text that we're going to use in our analysis. So, how do we define green innovation? Here we rely directly on the CPC classification. So the CPC has two categories that have particular relevance to us, O is so called YO two category, which contains all technologies relating to cm mitigation and adaptation, and y4s, which is essentially smart grids related innovation. So what we mean by green innovation, this paper is very much climate related innovation, decarbonization related innovation. And as you can see, the share of green innovation, so this is a share that sedation weighted 1980-2020 has increased quite a bit. Also what you would expect from P. Now, just zooming in in terms of the composition, the main nine technologies that are identified in that CPC taxonomy are CCS, climate adaptation, green buildings, decarbonizing buildings, greening ICT, green transportation, mostly EVs. Decarbonization of industrial processes, renewables, smart grids, and waste management. And as you can see in terms of composition over time, the two categories that have grown the most are climate adaptation and green ICT. But for the rest of the technologies, the split is fairly stable over time. Now, turning to automation. Here we rely on a recent contribution by our colleagues, David Demus Antoine Sept, Martin Olson, and Cars Asana, forthcoming in the JPE who classify patents as being related to automation. And for that, they use a keyword based approach that that's fairly detailed, and in which they focus on machinery innovation. So we're kind enough to share with us the CPC codes they've identified as being automation relevant at the six digit level. And so here, since we're looking really at automation with imaginary, the way to think about how we define automation is in terms of automation of the production process, industrial production process, so to speak. So here you can see this kind of like in U shape pattern over time in the share of automation patents since the 80s. And here that spike is really related to innovation in industrial robots, whereas here in the more recent it's more about digital automation in the 2010. All right. So now, how are we going to link those two datasets? How are we going to link innovation to scale content, patents to skills. So here we're going to use modern NLP techniques. More specifically, sentence transformers. I'm not going to have time to get into details of how to implement that. But the gist of it is that if you have two textural sources, which we do here, we have patent titles and abstracts, so that describes the content of a patent. And for each skill, we also have a paragraph describing the content of that skill. What sentence transformers will allow us to do is to compute a score of how semantically similar they are, so how semantically related they are. And that semantic similarity is how we're going to construct the link, essentially. So for each of the 1.6 million patents, we calculate a semantic similarity score with each of the 32,000 skills. So you can think of it as like a really large matrix with 1.6 million rows and 32,000 columns. Then we're going to aggregate those patents at the four digit CPC level, which is going to let us have our nine green technologies split out here because they're at the four digit level, and another eight for automation. And then we're going to define a threshold. So, I don't know if I have a mouse here just to give you one example. So what we get at that point is for each of these four digit technological categories, a distribution of semantic similarity, so we normalize it 0-1. So each of these is a skill. So we have the distribution of the 32,000 skills ranked by high semantically similar. They are to each of those technological categories. And we're going to choose a threshold here, and everything that's above that threshold, we're going to consider that skills that are above the threshold are characteristic of that particular technology. So we're going to call them marker skills. So here this is what you see. Go back over here. This is what you see here. For example, storm drains. That's a marker scale for adaptation, climate change adaptation. So the idea is that when we observe a job posting that requires the scale storm drains, then we know that that firm will stand to benefit from innovation in adaptation because of that link. Similarly here, y4s remembers the smart git grid, s technological category. On market scale for it is smart meter systems. Here, B 25 data that's actuators, A and market scale would be compuon umerical control. So moving to our job dataset, and the colors are wrong, but that's fine. This is supposed to be green. So essentially, here, these are real examples taken from the dataset. For this flood safety engineer requires a skill storm drains. So we know from that that in that particular firm, innovation in storm drain related technology in Y 02 A, the climate chain adaptation category, will stand to benefit that particular firm. Here, this automation technician has a CNC skill that's required. So the firm that employs them will stand to benefit from automation innovation in the CNC category. But of course, most of the ads we observe will have neither a green marker skill nor an automation market skill. So it will just be unclassified as it relates to our two technological classes. Now, when we look at the share, so our metric really is for each establishment or each firm, what is the share of ads that contain a green market skill or an automation market skill? And that's how we're going to define our technological adoption, technological exposure metric. So looking at it for green, It's a big crushed by the scale of automation, but there's still like an uptake of a time from 2010 onward, from 4% to 5%. So these are not re weighted. So this is like directly taken from the LCAs job ad, bear in mind that re weighted by employment shares, that the picture might be a bit different. But that's dwarfed obviously by the growth in exposure to automation. So the share of ads, highlighting adoption of automation technology really shot up over the past 15 years. Now, zooming in on green technologies, we see that green ICT is the biggest share here and that you have an uptake in smuggle adoption and industrial process decarbonization. And you see this like a slight increase 4-5% over the period. All right. So that's for the first, like constructing a measure of technical adoption at the firm level. Now, what about how to identify whether renovation in general is labor saving or labor augmenting. So here we borrow from David Otters recent paper in the QG, whereby they propose to operationalize that concept of being labor saving or labor augmenting. And the way they propose to do that is the following. So we know that labor saving innovation is meant to replace tasks that workers already conduct. So the idea they introduce is to look at the textural content of a patent and look at whether it's symetically similar to existing tasks that we already observed from datasets produced by the BLS. So essentially, the idea is that if a patent is symetically similar to existing work content, then it stands to replace workers in more likely fashion. Conversely, for laboring menting innovation, it's meant to complement workers. So the idea here is to look at you take a period, for example, a decade. You look at the job titles that will appear in the US Census at the end of that decade. And if a Paton fight before that relates to future job titles, Then the idea is that because labor augmenting innovation is meant to increase the number of occupation and create new jobs and new types of occupation, then if a patent relates to future job titles, then it's tend to be labor augmenting. And we already have all the data we need to implement the mythology. With our centers transformer approach, which is not what we're using, and apply it to green in technology classes, which also can't do in a dataset to look at what we observe for green novation. And what we observe what we obtain is this. There's a bit to impact here. So on the x axis, essentially what you have is the ratio of labor augmenting patents to labor saving patents. So the further to the right you are, the more labor augmenting you are, the further to the left you are, the more labor saving you are. Okay? Here in blue, you see broad technological classes that cover everything except for green technologies. The analysis is done at the four digit CPC level, at the technology class level, which is why you have a distribution for those broad technology classes, we only have one observation for each of the green technologies. And what this tells us is the following. First, that as I was mentioning earlier, green ICT and green buildings, they tend to be quite labor augmenting, actually compared to the rest of the technological classes tend to be amongst the most labor augmenting. It makes sense because if you look at the top two labor augmenting broad technology classes, ICT is very close to instrument information, which is the ICT technology class, and Green Buildings is a lot about sensors and electronics, which is also very related to electricity and electronics. So the fact that these these two stand together is what we would expect and it is confirmed by this nysis. Fversely, if you look at green transportation and compare it to broader transportation, green transportation tends to be a most the most labor saving type of transportation, really. And again, that we would expect because we know that producing, manufacturing an electric vehicle requires a lot less labor than manufacturing an EV IC vehicle, sorry. And so what this tells us is that innovation in the EV space tends to even reinforce that trend. Make it increasingly labor saving, so increasingly automated, so to speak, to produce decarbonized vehicles, electric vehicles. Here you see what I was mentioning earlier that amongst the most labor saving, you have smart grids and CCS, which again, are not very labor intensive technologies. So again, as expected. Also compute those metrics over time, and that's where we find what I was mentioning in the results preview. Here, we only look at the nine green technological categories. And when we look at it from the 80s onward, we find that earlier on, those green innovation green patents tended to be a lot more labor augmenting, and as we move onward, they tend to become more labor saving. So one way to interpret that that makes sense is that if you think of it in terms of an innovation cycle, earlier on, you kind of at the design stage of the energy transition, at the design stage of decarbonization. So you're really not considering implementation yet. So at that point, it makes a lot of sense for it to be labor augmentic, because it's meant to it's going to create a lot more new occupations, a lot more work because you're designing it, and it's going to be high scale occupations. Whereas, as we move towards the 2010s, we have an increased need for implementing the carbonization and the energy adicion. And at that point, it makes more sense to focus more on labor saving innovation, which are more needed when you get at the implementation stage at the R&D design stage. So now we have all of that. We're ready to answer our original question, which was, what is the impact of green an atomation innovation on labor emissions? So the metric I've introduced the novel metric of technology adoption. We can actually compute it over our time frame, 2010-2024, we can observe it dynamically over time, and we can aggregate it at various levels geographically. We could look at it at commuting zone level for regional kind of impact. We could compute it at the firm level, but we could also look at it at the establishment level because all we need is adds at the establishment level. And so that allows us To create an empirical design to assess the causal impact of an increase in innovation in green technologies and automation technologies on labor and environmental outcomes. So what we're going to consider as I was saying is long differences. So compared the early 2010s with the early 20 tents. And the reason we do that is that we know that technological diffusion is not a fast process. So you need to allow for at delay to re observe impacts. And finally, given the way we define our metric of technological adoption, there would obviously be a risk of endogenity, a risk of reverse causality. So the way we do this is that we're going to design an instrument for that change in technological adoption 2010-20 tents, and that instrument essentially going to consider that what motivates firm to adopt more green technologies or more automation technologies is going to be driven by innovation in those technologies outside the firm. So I'm just going to describe that more specifically. So just to have a common ground of what we're talking about, The way we can write our metric of technological adoption is the following. Consider an establishment I, consider the set of ads offered by that establishment I in a given period. And here this indicator function is going to be whether a given add A contains a market scales for technology K. So that share of ads is just a share of ads at the establishment level that pertains to a certain technology. So that's going to give us shares for each of the four digit technologies that we've identified. We can aggregate them then into our two main technological categories of interest, green, and automation. So we have those shares for each establishment over time. Now, The shift share that I was referring to is that we're going to look at the change in technology adoption between the 2010s and 20 tents. So we're going to look at the change in that share at the establishment level for green and for automation. As I was saying, this risks being very endogeneous. So we need to instrument for a plausibly exogenous instrument. The instrument we choose is to use a shift share type of instruments. I'm not going to get to too much detail, but essentially the idea is to look at the level of adoption in the baseline period, in the early 2010 for each of the technologies and use an exogenous shifter that could have driven the change in adoption. And here, the exhoit shifter we're going to use is innovation in each of these technologies. So in particular, We also want that innovation to not be endogeneous. So to make sure, since we're only looking at US based firms, right, to make sure that it's innovation happening outside of the firm, not only are we going to consider innovation happen outside the firm, we're also going to consider innovation happens outside of the US entirely. So we're no longer going to look at patents that are triadic for this particular instrument. We're going to look at so called diadic patents that are only find in two paid offices in the EPO and the JPO. And that's what we're going to use to construct our instruments. Okay. So in terms of our definition, as I was saying, the establishment is going to be a firm advertising within a commeting zone. The baseline period that we're going to use is 2010, 2014, so that's to get kind of a sufficient sample in each establishment to construct our shares. The outcome period is going to be 21 to 2021 to 2023. And the volume of innovation, the flow of innovation to construct the instrument, we're going to consider the flow innovation 2005-2015. So here we consider that effect that period. So implicitly, the hypothesis we're making is that we allow for kind of a six year delay for technical adoption from the Patent publication to observing effects on labor environmental outcomes. And here in this long difference, the types of outcome we're going to look at are employment, skills ratio, wages, and emissions. So I just have time to present the results, so that's great. Starting with number of jobs. So here, The dependent variable is the difference in the number of job ads offered at the establishment level 2021-2023 and the baseline period of 2010 to 2014. Okay. So that's this change in D log. So the way to read those coefficients is that a 1% change in the adoption metric of green technology drives a 0.4% change in the number of positions offered, right? So what we find is that green technology adoption drives employment creation. That establishments that adopt more green technology create more jobs. And again, we claim that this is a causal relationship because of our empirical design. Conversely, as we would expect from the literature, adoption of automation technology is actually a net destructor of jobs, like a 1% increase in our technological adoption metric for automation drives almost a 1% reduction in the number of jobs offered. Now, turning to the ratio of low and high skilled workers. So here, what we look at is the ratio between the number of high skilled positions offered to the number of low skill position offered. So an increase in that ratio will mean that the technological change we're looking at is skills bias towards high skilled workers, because it tends to create more jobs for high skilled workers than low skilled workers. And here what we find, as expected again from the literature, automation technological adoption is bias towards high skilled workers. For green innovation, we also find when we look at it by itself, it's less physically significant where we combine it with automation exposure, but also the magnitude is half that of automation adoption. So green innovation seems to have also the same characteristy of being biased towards high skilled workers, but to a lesser extent to a lower extent than automation. So the fears that it would polarize the job market towards higher skilled workers that is definitely warranted for automation technological adoption is less warranted for green innovation. Now, looking at wages, again, with all the caveats that I mentioned earlier, we only observed wages in 25% of our sample. And in addition to that, this is the offered salary. We don't know if it was actually the salary taken by by the person filling the position. But what we do find, which is not exactly great news, I suppose, is that both green and automation innovation tend to depress wages or green and automation adoption. Automation that was expected from the literature, green, that's a new contribution, and it's. It's more moderate again than automation, but it's still a pretty strong effect. And finally, our last result is looking at CO two emissions at the establishment level. So one caveat about that again is that the source of our emissions data is from the EPA, the EPA has a large emitter plants dataset. So we had to manually merge that with our Job data, which, as you can imagine, it was a lot of fun. The problem is there's very few establishments that remain in that dataset because the constraints are we need to have a match between the EPA dataset and Jobs dataset, and we need to observe it in the early 2010s and the early 2020. When you have all those restrictions in place, you're down to less than fewer than 1,000 observations, fortunately, few 1,000 establishments. So we don't achieve stistical significance here. But in terms of the signs, so we have the expected sign. You have a reduction in emission the more you adopt green technology. But reassuringly, we don't observe that increased adoption of automation technology would drive a growth in emissions. So we can reject the idea that increased automation technology adoption might be a detriment to emissions reduction, and that's actually quite reassuring for the green growth story that was mentioning earlier. So just in conclusion to recapitulate what we've been over, Gnovations impact is expected to be highly heterogeneous, depending on technology. H technologies are going to be quite labor saving. Others are going to be quite labor augmenting. However, as a broad category, it has become less and less labor augmenting over time. And we also have preliminary results that suggest that increases in adoption of green technologies at the firm and establishment level drives jobs, creations. We also have some suggestive evidence that this job creation is going to be a skills biased towards high skilled workers, but to moderate extent, certainly to a lower extent than for automation innovation. And reassuringly, we don't find any evidence that increased adoption of automation technologies might weaken emissions reduction moving forward. Just to give you a kind of a preview of what we're working on right now. So we exploring the heterogenity of those findings of our firm sizes. We already have evidence that a lot of automations, for example, job destruction potential is actually concentrated in larger firms. We don't find any evidence of it in smaller firms. We also looking at hetrogeny across industries across occupations, whether what the Litur said about how stem professions tend to benefit from the green transition is verified in our design. And finally, we also want to look at spillover effects at the more regional level at the commuting zone level in particular. The idea being that here, because our design requires that you observe the firm booth in 2010 in the early 2010 and early 2020s, we can't look at firm entry. And since green technology has been growing a lot over that period, we also want to know whether having regional specialization on green adoption of technology also yields benefits in terms of firm creation, the same space over that same decade all time span. That's it. Thank you very much. Take questions. Absolutely. So the bubble in AI electricity demand is after the end of your study. Yeah. You can't say anything about the reality of the importance of indsion? Absolutely. So it's a big concern, indeed that increased in power demand from AI would change those findings. So one thing is that that design looks at automation adoption within the firm. AI power demand is mostly concentrated in data centers that are mostly concentrated in like very few firms. So actually, that would not be reflected in the manufacturing firms emission that is what we're observing here. So we wouldn't I mean, Uh, that's something I didn't mention, but the sector we're limiting ourselves to is mining, utilities, and manufacturing here, because those are the firms that appear in the EPA High Mitter dataset. So we would to observe that. Um In terms of the magnitude of it, I know big tech companies are pretty big on moving towards the carbonizs of power, so that they're going to reopen three mile island. Microsoft stroke a deal to do that. They're definitely locating data centers in areas where there's a lot of availability of clean power. So the exact magnitude of that still remains to be seen, but in terms of observing it, it will be super concentrated in very few firms. So, I think in you would only see it in really scope three emissions and not really in scope one and two emissions. Pick it up a qual Essentially. Okay. We are a little late. Let me suggest we get five minute for sure. Thank you very much. My a very general topic was interested now on your view you were watching the energy transition for many years a. So what's your view on the impact of change in government or feeding of. Let's start with an easy and non polemic question. So I mean, we were just talking about that a couple of hours ago. I guess, in the case of the US, like the landmark climate related policy, we specifically designed to be as administration change proof as possible with a lot of funding going to red districts, essentially. So that would hopefully make it very hard for the incoming administration to repeal it. Now, what I'm more concerned about is the growing evidence we have back home in Europe of a growing backlash towards climate policy. So here in Europe, it's not a case that people don't believe that clime is real. It's not even the case that they don't support climate action, is that when they see what climate action actually means for the, you know, the purchasing power, their day to day life, then they start to balk a bit at it. And that part thing we really haven't solved it. And that's one of the driving motivation of that paper, too, that if we keep promising that large scale investment in climate change will deliver a lot of high quality, well paying jobs, and then it fails to deliver that. The pushback will be massive, and that ultimately will delay climate action massively. So I think to me that the main concern is rather that pushback on com policy may be strong enough to drive income, you know, new administrations that would actually be anti Cmin action, but that it would actually come from the population rather than from the administration, if you see what I mean? I was about to mention, yeah. I mean, what happened with. Yes, thanks. I have a question specifically about transportation industry. What you think vehicles on the automation side equal So actually, I mean, I haven't seen that much research on that. I think it would be a very interesting question to explore. What little I've seen is that as we know utilization rates of current vehicles are super low because they're privately owned and they stand still for 90% at the time. So the idea is that with autonomous vehicles, you could move to having vehicle fleets that would have a much higher utilization rate. And from the aggregate perspective, the resource intensity of delivering private transportation would be lowered. Whether that actually bears out. I mean, the same argument had been made about UBA 15 years ago and assessments that have been carried out since then revealed that it actually just has increased demand for private transportation, has increased aggregate emsions, where we could assess it. So I'm not sure we actually delivered that promise, but that's what proponents of that approach are advocating at least. That's a great question that actually relates to two papers. Thanks On the first aspect, most of the job that is being created right now or most of the jobs that are recognizably green jobs actually are towards the lower end of the skies distribution. So if you look at within occupation, an installer that does green installations will tend to be more skilled. Than a non green installer. One way to think about this, if you think about heat pump installations, a plumber that can also install heat pumps needs extra qualifications to be able to install heat pump. That's what I mean by being more skilled with an occupation. But if you look at where growth and green jobs is happening, it's mostly amongst low skilled workers, because what we need to make decarbonization happen is actually a lot more installations, technicians, maintenance technicians, construction workers, rather than engineers and sciences. I mean, we also need them, right? But for the actual day to day work of implementing the decarbonization, that's not what you need. So completely agree with you on that point. However, walking back to the earlier point about pushback, if you don't take into account whether energy transition will affect spatial inequalities, then you're in for a massive pushback. In particular, you mentioned the rust belt, that's exactly an example where that was not well handled. And if you concentrate economic difficulties, particularly, here we're looking really on the other the green jobs aspects in this paper. But if you think on the flip side of that story about foss intensive jobs that are going to disappear in the decarbonization story, well, What we find in another of our papers is that those false intensive jobs, particularly in the US, tend to be the last remaining well paying jobs in relatively impoverished communities. The posted chart for this would be like Northern Dakota with the B in jail or like the Appalachians. If you remove those mining jobs from those communities, they have nothing left. And the fact that you're creating, solar PV solar jobs in California is not going to do them a whole lot of good. So being careful about that and about this impact, I think is crucial to avoid the kind of pushback that would set us back ten or 15 years. So first ask.
