摘要：When information acquisition is costly but flexible, a principal may rationally acquire information that favors one group over another. The former group faces incentives to invest in becoming productive, while the latter is discouraged from such investments. In turn, the principal largely overlooks the productivity differences between groups and primarily promotes the invested group, unless the underinvested group surprises him with a genuinely outstanding outcome. We show that, when attention...

摘要：This paper studies how social networks (might fail to) shape agricultural practices. We exploit (1) a unique census of agricultural production nested within delineated land parcels and (2) social network data within four repopulated villages of rural Vietnam. In the first step, we extract exogenous variation in network formation from home locations within the few streets that compose each village (populated through staggered population resettlement), and we estimate the return to social links ...

摘要：Which countries should aim for regulatory cooperation, and to what extent should they pursue it? We develop an imperfectly competitive trade model that accounts for differences in technology and regulatory preferences regarding local consumption externalities across countries. Each country sets unique product standards, and firms incur costs when tailoring products to different markets. Trade occurs when the benefits of comparative advantages outweigh the desire for asymmetric regulations. Our...

摘要：This paper examines the impact of data sharing among mobile apps, leveraging iOS's policy that limits tracking users using identifiers. We find that this restriction decreases average new downloads by 3.96%. The effect is primarily driven by large apps that heavily rely on third-party data to acquire users (resulting in overlapping effects), and developers who lack first-party data (resulting in a lack of information advantage). However, new app introductions, particularly by first-time develo...

摘要：This paper provides the first statistical study of political differences between fact-checkers. I collect a comprehensive dataset of articles published by the six main general-interest French fact-checkers up until July 2021 and identify the political orientations of entities that are fact-checked. French fact-checkers commit to non-partisanship. However, they are affiliated with a media outlet. I find differences in fact-checkers' political content, which reflect the media outlets' slant. Thi...

摘要：This paper investigates whether and why laws requiring chain restaurants to post calories on menus and menu boards work. We develop a model of calories consumed that highlights multiple potential channels through which these laws influence choice and that outlines an empirical strategy to disentangle these alternatives. We test the predictions of our model using data from the Behavioral Risk Factor Surveillance System on body mass index and consumer well-being, as well as our own surveys on ho...

摘要：Within a general macroeconomic environment, I derive the welfare effect of capital tax changes in terms of estimable sufficient statistics. Lower capital-labor substitutability in production not only induces a stronger responsiveness of wages and financial returns, but it also reduces the deadweight loss of capital tax hikes. Thus, contrary to conventional wisdom, optimal capital taxes may be higher precisely when trickle down effects are stronger. I apply my theoretical results to US data and...

摘要：We study the effects of financial frictions on firm exit when firms face large liquidity shocks. We develop a simple model of firm cost-minimization, where firms' borrowing capacity to smooth temporary shocks to liquidity is limited. In this framework, firm exit arises from the interaction between this financial friction and fluctuations in cash flow due to aggregate and sectoral changes in demand conditions, as well as more traditional shocks to productivity. To evaluate the implications of o...

摘要：Transfers from parents-either in the form of gifts or inheritances-have received much attention as a source of inequality. This paper uses administrative data for the population of Norway to examine the share of the Total Inflows (defined as the capitalized sum of net labor income, government transfers, and gifts and inheritances received over the period) accounted for by capitalized gifts and inheritances. Consistent with other work, we find that there is much inequality in the receipt of gif...
