We propose and implement a procedure to optimally hedge climate change risk. First, we construct climate risk indices through textual analysis of newspapers. Second, we present a new approach to compute factor mimicking portfolios to build climate risk hedge portfolios. The new mimicking...

We study the nonlinearities present in a standard monetary-labor-search model modified to have two groups of workers facing exogenous differences in job finding and separation rates. We use our setting to study the racial unemployment gap between Black and white workers in the United States. A...

This paper studies the problem of endogenous coalition formation in contests: how players organize themselves in groups when faced with the common objective of securing a prize by exerting costly effort. The model presented adopts an axiomatic approach by assuming certain properties for the...

This paper analyses the effects of an introduction of a retail central bank digital currency (CBDC) on bank intermediation in a tractable general equilibrium model with heterogeneous bank deposits and an imperfectly competitive loan market. The agents in the economy have preferences over holding...

Firms often discourage certain categories of individuals from buying their products, seemingly at odds with typical assumptions about profit maximization. This paper provides a potential rationale for such firm behavior: Consumers seek to signal that they have “desirable” ideological values...

Previous evidence shows that better insurance coverage increases medical expenditure. However, formal studies on the effect of spending on health outcomes, and especially mental health, are lacking. To fill this gap, we reanalyze data from the Rand Health Insurance Experiment and estimate a...

We study the effect of exposure to colonial public primary education on contemporary education outcomes in Tunisia. We assemble a new data set on the location of schools with the number of pupils by origin, along with population data during the French protectorate (1881–1956). We match those...

At the time of writing, the Riemann Hypothesis (RH) is one of the major unsolved problems in pure mathematics. In this note, a parameterized family of non-cooperative games is constructed with the property that, if RH holds true, then any game in this family admits a unique Nash equilibrium

Does growing up with a sister rather than a brother affect personality? In this paper, we provide a comprehensive analysis of the effects of siblings’ gender on adults’ personality, using data from 85,887 people from 12 large representative surveys covering 9 countries (the United States,...

Fees are omnipresent in markets but, with few exceptions, are omitted in economic models—such as Double Auctions—of these markets. Allowing for general fee structures, we show that their impact on incentives and efficiency in large Double Auctions hinges on whether the fees are homogeneous...
