Will Artificial Intelligence Get in the Way of Achieving Gender Equality?
The promise of generative AI to increase human productivity relies on developing skills to become proficient at it. There is reason to suspect that women and men use AI tools differently, which could result in productivity and payoff gaps in a labor market increasingly demanding knowledge in AI. Thus, it is important to understand if there are gender differences in AI-usage among current students. We conduct a survey at the Norwegian School of Economics collecting use and attitudes towards ChatGPT, a measure of AI proficiency, and responses to policies allowing or forbidding ChatGPT use. Three key findings emerge: first, female students report a significantly lower use of ChatGPT compared to their male counterparts. Second, male students are more skilled at writing successful prompts, even after accounting for higher ChatGPT usage. Third, imposing university bans on ChatGPT use widens the gender gap in intended use substantially. We provide insights into potential factors influencing the AI adoption gender gap and highlight the role of appropriate encouragement and policies in allowing female students to benefit from AI usage, thereby mitigating potential impacts on later labor market outcomes

HANK's Response to Aggregate Uncertainty in an Estimated Business Cycle Model
This paper studies a HANK model with agents who respond to both idiosyncratic and aggregate uncertainty. Since aggregate uncertainty is modeled as ambiguity, it affects both the steady state and the linearized dynamics, allowing for fast computation and estimation with linear methods. The estimated model jointly fits cyclical variation in US macro aggregates and asset prices. In the presence of portfolio frictions, aggregate uncertainty shocks are a powerful driver of the business cycle, more so than idiosyncratic uncertainty shocks. Their effect is much stronger than in a representative agent model: portfolio substitution by capital owners helps fit investment and return dynamics.

The war of attrition under uncertainty: Theory and robust testable implications
We study the war of attrition with symmetric information when players’ payoffs depend on a homogeneous linear diffusion. We first show that a player’s mixed Markov strategy can be represented by an intensity measure over the state space along with a subset of the state space over which the player concedes with probability 1. We then show that, if players are asymmetric, then, in all mixed-strategy Markov-perfect equilibria, these intensity measures must be discrete, and characterize any such equilibrium through a variational system for the players’ value functions. We illustrate these findings by revisiting the standard model of exit in a duopoly under uncertainty and construct a mixed-strategy Markov-perfect equilibrium in which attrition takes place on path despite firms having different liquidation values. We show that firms’ stock prices comove negatively over the attrition zone and exhibit patterns documented by technical analysis

The Role of Skills and Sorting in Explaining Wage Inequality
A large literature argues that technological change since the 1980s altered the demand for workers’ skills, increasing wage inequality and polarization. By estimating a model of occupational choice using panel data from the Survey of Income and Program Participation (SIPP), I find that changes in the supply of workers’ skills were also major driving factors in increasing inequality and polarization. Specifically, I find that (1) as tasks in high-skill jobs have become increasingly complex, the distribution of workers’ ability to perform those tasks has become more dispersed, (2) workers’ ability to perform low-skill work tasks has become more homogenous, and (3) workers have increasingly sorted into occupations by skill level, even if this does not maximize their income. These results suggest that skill formation has been a key channel through which long run changes in the nature of work have affected wage inequality. Finally, to obtain my estimates I prove a new identification result in a multi-dimensional potential outcome model and show how to robustly estimate it semiparametrically adapting results from mixture models.

Why Do People Discount? The Role of Impatience and Future Uncertainty
Despite the intuition that risk preferences affect intertemporal choice because the future is uncertain, time discounting is commonly regarded as a reflection of impatience. Our experimental data show that approximately 43% of the observed time discounting can be explained by an aversion against future uncertainty rather than impatience, even when controlling for utility curvature. Future uncertainty receives disproportional weight because subjects engage in subproportional probability weighting, a behavioral regularity that does not feature in the standard risk framework of most intertemporal choice models. We find that many people do not demand compensation for waiting but rather for an uncertain future

Can microfinance unlock a poverty trap for some entrepreneurs" (With Abhijit Banerjee, Emily Breza and Cynthia Kinnan)
Can microcredit help unlock a poverty trap for some people by putting
their businesses on a different trajectory? Could the small microcredit treatment effects often
found for the average household mask important heterogeneity? In Hyderabad, India, we find
that “gung ho entrepreneurs” (GEs), households who were already running a business before
microfinance entered, show persistent benefits that increase over time. Six years later, the
treated GEs own businesses that have 35% more assets and generate double the revenues as
those in control neighborhoods. We find almost no effects on non-GE households. A model
of technology choice in which talented entrepreneurs can access either a diminishing-returns
technology, or a more productive technology with a fixed cost, generates dynamics matching
the data. These results show that heterogeneity in entrepreneurial ability is important and
persistent. For talented but low-wealth entrepreneurs, short-term access to credit can indeed
facilitate escape from a poverty trap.

Codification and Technology Absorption: Evidence from Trade Patterns
écrit avec Réka Juhász, Shogo Sakabe, David E. Weinstein,
This paper studies technology absorption around the world in the late nineteenth
century. We construct several novel datasets to test the idea that the codification of
useful knowledge in the vernacular was necessary for countries to absorb the technologies
of the Industrial Revolution. Using the rapid and unprecedented codification
of useful knowledge in Meiji Japan as a natural experiment, we show that productivity
growth in Japan was higher in industries that had a higher supply of Western
useful knowledge, but only after the Japanese government undertook a large public
good investment to provide this knowledge to its citizens. We find no similar patterns
in other parts of the world which did not codify knowledge. Taken together,
our findings shed new light on the frictions associated with technology diffusion, and
offer a novel take on why Meiji Japan was unique among non-Western countries in
successfully industrializing during the first wave of globalization.

The Who, What, When, and How of Industrial Policy: A Text-Based Approach
écrit avec Nathan Lane, Emily Oehlsen and Verónica C. Pérez
Since the 18th century, policymakers have debated the merits of industrial policy
(IP). Yet, economists lack basic facts about its use. This study sheds light on
industrial policy by measuring and studying global policy practice for the first
time. We first create an automated classification algorithm for categorizing
industrial policy practice from text. We then apply it to a global database of
commercial policy descriptions and quantify policy use at the country, industry,
and year levels (2009-2020). These data allow us to study fundamental policy
patterns across the world. We highlight four findings. First, IP is common (25%
of policies in our database) and has expanded since 2010. Second, instead of
blunt tariffs, IP is granular and technocratic. Countries tend to use subsidies
and export promotion measures, often targeted at individual firms. Third, the
countries engaged most in IP tend to be wealthier (top income quintile) liberal
democracies. In our data, IP is rarer among the poorest nations (bottom quintile).
Fourth, IP is targeted toward a subset of industries and is highly correlated with
an industry’s revealed comparative advantage. We show that industrial policy is
a prominent feature of the global economy and a far cry from industrial policies
of the past.

The Global Allocation of Extractive Windfalls
écrit avec Ninon Moreau-Kastler
Profits of extractive companies are strongly linked to commodity prices, but little is known on the distribution of those windfall profits along their global value chains. We investigate how fluctuations in profits arising from commodity price changes are distributed worldwide using a multi-country unconsolidated firm-level database matched with production data covering a large number of extractive firms from 2012 to 2022. We find that the profits of subsidiaries located in tax havens are more elastic to changes in commodity prices compared to other subsidiaries. This elasticity is larger when commodity prices increase compared to price decreases. Our results hold when taking into account sector differences between countries.

Cognitive Barriers to Impact Investing
Sustainable investing has been gaining traction as a means to speed up the environmental transition. Recent theoretical work highlights that a sustainable investor looking to maximize their impact should focus not just on their own stocks' emissions, but should also internalize the whole market's emissions – following a broad mandate. Sustainable investors should therefore coordinate with other fellow sustainable investors, as well as with the market as a whole. The goal of this project is to explore behavioral barriers to broad-mandate investing. In a first experiment, we find that some market structures make broad-mandate investing very counterintuitive for investors, irrespective of their preferences. Further experiments are planned in order to identify the precise cognitive mechanism at play

Feedback, Overconfidence and Job Search Behavior
Job seekers face uncertainty about their abilities, and whether these match with job requirements. Such uncertainty may result in sub-optimal job search outcomes and job matches. We conduct a field experiment among job seekers in Addis Ababa, Ethiopia. Participants underwent a skill assessment and were asked about their willingness to pay (WTP) for information about their relative performance on a test of general intelligence. WTP is positive for about 80 percent of the population, and is associated with gender and personality. Feedback provision leads individuals to update their beliefs which only persists for individuals with low WTP. We provide evidence that suggests imperfect recall as potential mechanism for the lack of persistence. Feedback increases job search intensity but relatively less for initially overconfident individuals and those with negative or zero WTP. This results in lower realized wages for these groups. The heterogeneity in belief updating, recall and job search behavior is consistent with some overconfident job seekers being unable to forget information and, thus, to maintain motivated beliefs, but being sophisticated about this inability to forget.

Targeted Monetary Policy as Financial Stability Regulation: Quasi-Experimental Evidence from the 1920s
How should policy-makers tame excessive credit growth? I exploit a single natural experiment to estimate the comparative causal effects of different financial stability policies on bank-level credit, bank survival and real outcomes. In 1920, four Federal Reserve Banks hiked their interest rate indiscriminately to safeguard financial stability. Another four Reserve Banks employed targeted rate action aimed at over-leveraged banks instead. The remaining Federal Reserve districts did not take any measures. For identification, I draw on geographic border discontinuities across districts with different policy choices. In direct horse races, targeted policy dampened the boom more successfully, led to fewer bank failures and produced better real outcomes than uniform rate hikes.

Histoire économique et données en miettes — comment écrire l'histoire économique de la Chine des Song (960-1279) ?
Comment écrire une histoire économique sans archives ? Comment évaluer des volumes de production ou de consommation à partir de chiffres parfois nombreux mais disparates, recensés dans des régions différentes et dans des conditions souvent imprécises, voire douteuses ? Comment comparer des prix quand les monnaies diffèrent d’une région à l’autre, en incluant des monnaies « privées », circulant sur les marchés et plus ou moins tolérées par les autorités locales ? Bref, qu’est-ce qu’une histoire économique sans quantification fiable ? C’est à ce défi qu’est confronté l’historien de la Chine impériale au tournant du premier et du second millénaires, alors que les textes et l’archéologie attestent que l’empire des Song connaissait un essor sans précédent de l’économie marchande, soutenue par un développement des instruments financiers dont le premier papier-monnaie émis à partir de 1024. Le présent exposé cherchera à montrer que l’interprétation des données disponibles, y compris chiffrées, permet cependant de mettre en évidence la cohérence des mécanismes qui permit aux différents échelons de l’État dynastique de diversifier leurs finances tout en faisant de la Chine un des grands carrefours des échanges asiatiques.

Behavioral Foundations of Model Misspecification
écrit avec Aislinn Bohren
We link two approaches to biased belief formation: non-Bayesian updating rules and model misspecification. Each approach has advantages: updating rules transparently capture the underlying bias and are identifiable from belief data; misspecified models are `complete' and amenable to general analysis. We show that misspecified models can be decomposed into an updating rule and forecast of anticipated future beliefs. We derive necessary and sufficient conditions for an updating rule and belief forecast to have a misspecified model representation, show the representation is unique, and construct it. This highlights the belief restrictions implicit in the misspecified model approach. Finally, we explore two ways to select belief forecasts---introspection-proof and naive consistent---and derive when a representation of each exists.

Irrigation as mitigator for migratory aspirations following drought
écrit avec Alix Debray, Lucile Dehouck, Katrin Millock
This article aims to contribute to the ongoing debate on the causal relationship between climate and migration, which has remained inconclusive and often fails to consider alternative adaptive mechanisms. Specifically, we investigate the effect of drought on aspirations to migrate in and out of 11 West African countries, controlling for irrigation. Our analysis uses cross-country comparable Gallup World Poll surveys combined with fine-grained geo-local information on irrigation coverage as well as drought occurrence and intensity. Our preliminary findings confirm the potential of irrigation to diminish the negative effect of drought on migration aspirations. However, further robustness checks and estimations on different samples will allow determining whether this correlation would encourage individuals to continue investing in their local communities or rather enable them to fulfil their migration aspirations. Overall, the article highlights the potential of alternative adaptation mechanisms in shaping migration patterns and emphasizes the need for a more nuanced understanding of the climate-migration nexus

Green Road is Open: Economic Pathway with a Carbon Price Escalator
The paper develops the concept of "Economic Pathways" (EPs), which char-
acterizes theory-based scenarios for an economy that strives for decarbonization
by the middle of the century. The theoretical framework derives closed-form an-
alytical solutions for consumption, innovation, emissions, and population. The
EPs di§er in the stringency of assumed policies and associated income and emis-
sion development. Unlike the well-known "Shared Socioeconomic Pathways",
they allow the inclusion of important causalities between the economy and the
environment and considerably narrow down the scope of likely future develop-
ments. The quantitative part serves to illustrate the long-term consequences of
climate policy. I show that deep decarbonization only moderately delays eco-
nomic development, but requires increasing escalation of the carbon price. The
paper argues that the adoption of more stringent climate policies becomes more
likely as the phase-out of fossil fuels increases. The "Green Road" is not only
feasible but also attractive and realistic.

Markups and Markdowns in the French Dairy Market
écrit avec Rémi Avignon
Separately measuring firm buyer and seller power is important for policy-making, but chal-
lenging. In this paper, we suggest a new methodology to do so and apply it to French dairy
processors. These firms exert buyer power when purchasing raw milk, and seller power when
marketing dairy products. The analysis is based on plant-level data on dairy firms, with obser-
vations on prices and quantities of raw-milk input by origin and output by product from 2003
to 2018. We rely on a production function approach to estimate total margins. The existence
of a commodity, (i) substitutable as an input or as an output, and (ii) exchanged on global
markets where firms are price-takers, allows us to separately estimate firm-origin markdowns
and firm-product markups. We show this methodology can also be useful in other contexts,
with more limited data. Markdown estimates imply that dairy firms on average purchase raw
milk at a price 16% below its marginal contribution to their profits, while markup estimates
indicate that firms sell dairy products at a price exceeding their marginal costs by 41%. Our re-
sults show substantial variations in buyer and seller power exploitation across firms, products,
and time. We analyze how shocks to local farmer costs and international commodity prices
pass through the supply chain. Processors partially absorb such shocks by adjusting markups
and markdowns, thus smoothing variations in farmer revenues. It further implies that 65% of
subsidies are currently diverted from farmers due to processor buyer power. A price floor on
raw milk could be an alternative welfare-improving policy.

Allocation Mechanisms with Mixture-Averse Preferences
écrit avec Uzi Segal
Consider an economy with equal amounts of N types of goods, to
be allocated to agents with strict quasi-convex preferences over lotteries. We show that ex-ante, all feasible and Pareto efficient allocations
give almost all agents binary lotteries. Therefore, even if all preferences are the same, some identical agents necessarily receive different
lotteries. Our results provide a simple criterion to show that many
popular allocation mechanisms are ex-ante inefficient. Assuming the
reduction of compound lotteries axiom, social welfare deteriorates by
first randomizing over these binary lotteries. Efficient full ex-ante
equality is achieved if agents satisfy the compound independence axiom.

In or Out? Xenophobic Violence and Immigrant Integration. Evidence from 19th century France
écrit avec Stephane Wolton
How do foreigners respond to xenophobic violence? We study Italian immigrants' response to anti-Italian violence triggered by the assassination of the French president by an Italian anarchist in June 1894. Using French nominative census records from 1881, 1886, 1891 and 1896 and official naturalization decrees published between 1887 to 1898, we study the decision of Italian immigrants to either leave their local communities or apply for naturalization using a difference-in-differences design, comparing the change in exit and naturalization application rate of Italians before and after the assassination to that of other foreigners in the same period. We document how xenophobic violence triggered an increase in both exits and naturalization applications, with greater violence or threat thereof associated with more exits. We also find that well-integrated Italians, as proxied by intermarriage, occupation, and position in the household, are more likely to naturalize and less likely to exit than less integrated ones and less integrated ones are more likely to exit. We present a stylized model of immigrants' choices to make sense of these findings.

The Cost of Air Pollution for Workers and Firms
This paper shows that even moderate levels of air pollution, such as those found in Europe, harm the economy by decreasing firm performance. We estimate the causal effect of fine particulate matter pollution (PM2.5) on firms' monthly sales and worker absenteeism using matched employer-employee data from France from 2009 to 2015. We exploit variation in air pollution induced by changes in monthly wind directions at the postcode level. We find that a 10 percent increase in monthly PM2.5 exposure decreases sales in the following two months by 0.7 percent on average, with heterogeneous effects across sectors ranging from a 0.4 percent decrease in manufacturing, construction, and business-to-business trade and services, 1.0 percent in food retail and supermarkets, to 1.4 percent in other business-to-consumer services. Concurrently, worker absenteeism due to sick leave increases by 1 percent, underscoring the negative effects of air pollution on workers' health. Yet sales losses are an order of magnitude larger than we would expect if worker absenteeism was the main channel underlying sales decrease. A heterogeneity analysis by sector and industry highlights two other important mechanisms: a detrimental effect of air pollution on the productivity of non-absent workers, and on local demand. The results from our study suggest that reducing air pollution in line with the World Health Organization's guidelines generates economic benefits largely exceeding the cost of regulation in France.

The Value of a Loss: The Impact of Restricting Tax Loss Transfers
écrit avec with Theresa Bührle, Elisa Casi and Johannes Voget
We study the economic consequences of anti-loss trafficking rules, which disallow the use of loss carry-forwards as tax shield after a substantial ownership change. We use staggered changes to anti-loss trafficking rules in the EU27 Member States, Norway and United Kingdom from 1998 to 2019 and find that limiting the transfer of tax losses reduces the number of M&As by 18%. The impairment is driven by loss-making targets. Turning to the broader impact on industry dynamics, we find decreases in survival rates of young companies in response to tighter regulations. Some of these start-up deaths are compensated by new firm entrants. We further detect that loosening of regulation spurs firm entry and survival. Finally, tightening (loosening) anti-loss trafficking rules impairs (increases) return on assets, especially for R&D-intensive firms that are more prone to loss-making in their life cycle.

Does Land Inequality Magnify Climate Change Effects? Evidence from France
This paper investigates how the concentration of farmland mediates the impact of climate change on agricultural productivity, with direct implications on resilience to heatwaves. We use a unique combination of French cadastral data and satellite imagery to demonstrate that more unequally distributed land entail greater losses during and after climatic shocks, primarily due to a lack of crop diversity resulting from specialisation. Contrarily to what is found in natural ecosystems in the biology literature, we uncover a productivity-resilience tradeoff, according to which more unequal regions, i.e, less diverse, tend to be less resilient but more productive. Our findings have implications for farmers and policymakers, who should consider these tradeoffs to ensure food security and price stability in the face of the climate crisis.

A tail of labor supply and a tale of monetary policy
écrit avec Filippo Ferroni Chicago Fed, Haroon Mumtaz Queen Mary University of London and Angeliki Theophilopoulou Brunel University London
We study the interaction between monetary policy and labor supply decisions at the household level. We uncover evidence of heterogeneous responses and a strong countercyclicality of hours worked in the left tail of the income distribution, following a monetary policy shock in the U.S. and the U.K. That is, while aggregate hours and labor earnings decline, employed individuals at the bottom of the income distribution increase their hours worked in response to an interest rate hike. Moreover, their response is stronger in magnitude relative to other income groups. We rationalize this using a two-agent New-Keynesian (TANK) model where our empirical findings can be replicated with heterogeneity in the sensitivity of marginal utility of consumption and a stronger income effect for the Hand-to-Mouth households. This setup uncovers a novel channel of transmission of monetary policy via inequality generated by the Hand-to-Mouth substitution of leisure for consumption following a negative income shock. Using a quantitative model with both intensive and extensive margin of labor
supply that replicates our evidence, we show that this new channel reduces the amplification of monetary policy via inequality generated by the heterogeneous behavior of unemployment along the income distribution.

Firm Organization Under Cover-Ups
This paper explores the dynamics of optimal organizational hierarchies in environments where supervisors may engage in cover-ups upon detecting mistakes. Employing a theoretical model, I investigate how firm size, the cost of mistakes, and their probability influence the wage structure within firms. I discuss the potential implications of organizational culture and the likelihood of cover-ups on the optimal firm hierarchy. This study contributes to the understanding of optimal organizational design and provides insights for firms seeking to mitigate the risks associated with errors and cover-ups in hierarchical structures

Beliefs About Maternal Labor Supply
écrit avec Teodora Boneva, Marta Golin, and Katja Kaufmann
We provide representative evidence on the perceived returns to maternal labor supply. A mother’s decision to work is perceived to have sizable impacts on child skills, family outcomes, and the mother's future labor market outcomes. Beliefs about the impact of additional household income can account for some, but not all, of the perceived positive effects. Perceived returns are predictive of labor supply intentions under different policy scenarios related to childcare availability and quality, two factors that are also perceived as important. An information experiment reveals that providing information about benefits of mothers working causally affects labor supply intentions.

Gender Promotion Gaps in Knowledge Work: The Role of Task Assignment in Teams
écrit avec Cagatay Bircan, Guido Friebel ,Tristan Stahl
Using rich data on personnel records, work assignments, and performance in a financial
institution, we uncover the mechanisms leading to promotion gaps in knowledge
teamwork. There is a substantial promotion gap for women in early careers. Analyzing
over 10,000 investment projects, we find that assignments to project team leaderships
(a “promotable” task) are crucial in explaining the gaps in promotions and affect longterm
careers. We find causal evidence that male supervisors favor male bankers. A
survey among employees indicates that women perceive to be disadvantaged in the
assignments of tasks, but they do not differ in aspirations and demand for these roles.
