How much do individuals contribute to team output? I propose an econometric framework to quantify individual contributions when only the output of their teams is observed. The identification strategy relies on following individuals who work in different teams over time. I consider two production...

We study an economy where consumers and merchants interact on a two-sided platform. The platform gathers consumer data and sells it to merchants. Data sharing increases gains from trade by improving match quality, but also generates two externalities which increase the market power of the platform...

We identify a new dynamic agency problem: that of incentivising the prompt disclosure of productive information. To study it, we introduce a general model in which a technological breakthrough occurs at an uncertain time and is privately observed by an agent, and a principal must incentivise...

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,...

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...

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...
