This paper studies how competition affects firms' expectations in a new dynamic general equilibrium model with rational inattention and oligopolistic competition where firms acquire information about their competitors' beliefs. In the model, firms with fewer competitors are less attentive to...

We study the role of employment protection legislation (EPL) in boosting employment among older workers. Our analysis juxtaposes the quantitative employment gains with the qualitative "deadwood labor" problem that such gains entail. We do so by conducting a comprehensive analysis of the sharp...

A prominent explanation for why trade is not free is politicians' desire to protect some of their constituents at the expense of others. In this paper we develop a methodology that can be used to reveal the welfare weights that a nation's import tariffs implicitly place on different groups of...

We study the causal interpretation of instrumental variables (IV) estimands of nonlinear, multivariate structural models with respect to rich forms of model misspecification. We focus on guaranteeing that the researcher's estimator is sharp zero consistent, meaning that the researcher concludes...

This paper investigates to what extent the 1998 reform of Sweden's public old-age pension system contributed to the increase in extensive margin labor supply among older workers seen in the country in recent decades. We use a large data set containing all males and females born in Sweden between...

Unlike most advanced countries, the U.S. does not have a federal paid sick leave (PSL) policy; however, multiple states have adopted PSL mandates. PSL can facilitate healthcare use among women of child-bearing ages, including use of family planning services such as contraception, in-vitro...

Motivated by a recent literature on the double-descent phenomenon in machine learning, we consider highly over-parameterized models in causal inference, including synthetic control with many control units. In such models, there may be so many free parameters that the model fits the training data...

The growing discussions of impact investing and stakeholder capitalism have increased interest in measuring companies' social impact. We conceptualize corporate social impact as the welfare loss that would be caused by a firm's exit. To illustrate, we quantify the social impacts of 74 firms in...

Since 1967, all French firms with more than 100 employees are required to share a fraction of their excess-profits with their employees. Through this scheme, firms with excess-profits distribute on average 10.5% of their pre-tax income to workers. In 1990, the eligibility threshold was reduced...

Many jurisdictions levy sizable fines and fees (legal financial obligations, or LFOs) on criminal defendants. Proponents argue LFOs are a "tax on crime" that funds courts and provides deterrence; opponents argue they do neither. We examine the fiscal implications of lowering LFOs. Incentives to...
