Heterogeneous firm models are central to the modern economics literature. In this context, we revisit a central feature of these models: the nature of idiosyncratic shocks faced by firms. Using firm level data, we show that the commonly assumed parametric distributions of the shocks firms face...

We use data from the U.S. airline industry to test the hypothesis, consistent with the general equilibrium oligopoly model of Azar and Vives (2021), that inter-industry common ownership should be associated with lower prices in product markets. We find that, as the model predicts, increases over...

We study how transboundary, intergovernmental fire and haze negotiations interact with local, subnational government collusion and capture in a decentralized country. The local government collusion and capture problem is modelled as a competing principals and common agency problem that interacts...

Data access is an important topic in Europe and around the world, with the potential to trigger benefits for many undertakings, for instance by improving product quality and spurring innovation. At the same time, there are a number of issues around sharing data, ranging from potential competition...

We propose a Marshallian model for price and allocation adjustments in parallel continuous double auctions. Agents quote prices that they expect will maximize local utility improvements. The process generates optimal allocations in the limit. In experiments designed to induce CAPM equilibrium,...

A large body of work highlights the key role of information reporting for tax enforcement and the development of modern tax systems. However, information reporting is not always sufficient to improve tax collection. Using micro-level administrative tax and custom data covering the universe of...

Gradient descent during the learning process of a neural network can be subject to many instabilities. The spectral density of the Jacobian is a key component for analyzing robustness. Following the works of Pennington et al., such Jacobians are modelled using free multiplicative convolutions from...

The diffusion of social media coincided with a worsening of mental health conditions among adolescents and young adults in the United States, giving rise to speculation that social media might be detrimental to mental health. In this paper, we provide the first quasi-experimental estimates of the...

We analyze inference on partially identified parameters in possibly misspecified incomplete models. Misspecification can make identified sets of parameters spuriously tight or even empty, which raises a challenge for interpreting identification results. This paper puts forward an information-based...

We develop a foundational model of the non-market allocation of resources through grantmaking. By casting the problem in a supply and demand framework in spite of the absence of prices, we characterize the equilibrium level of applications and acceptance standard. On the demand side, agents with...
