We consider the problem of allocating multiple units of an indivisible object among a set of agents and collecting payments. Each agent can receive multiple units of the object. We assume that preferences exhibit both nonincreasing marginal valuations and nonnegative income effects.We propose a...

During the last thirty years, U.S. bank concentration has been growing over time, as has bank capital ratio, which has been rising and already well above the minimum capital requirement. To explain these findings, I develop a tractable dynamic model with two key elements: financial constrained...

The impact of the Covid-19 pandemic on the UK labour market has been extremely heterogeneous across occupation and industrial sectors. Using novel data on job search, we document how individuals adjust their job search behaviour in response to changing employment patterns across occupations and...

Sender conveys scarce information to a number of receivers to maximize the sum of receiver payoffs. Each receiver’s payoff depends on the state of the world and an action she takes. The optimal action is state contingent. Under mild regularity conditions, we show that the payoff of each...

We develop a theory that addresses the existence of stable vaccine allocations in a political economy where vaccination offers both private and social benefits. These are allocation policies that a political leader can enforce without losing their popularity. We show that a stable allocation may...

This paper studies whether countries’ speeches at the United Nations General Assembly matter for international aid allocation. I use a supervised machine learning algorithm called wordscore and 7,533 different statements from 198 countries made in the period from 1975 to 2018 to measure...

I find substantial differences in the extent of misallocation across male and female-led establishments spanning many low and middle-income countries. In South American and South Asian countries female establishments face higher distortions to operating a business, whereas in Eastern European...

What accounts for income per capita and total factor productivity (TFP) differences across countries? We study resource misallocation across heterogeneous production units in a general equilibrium model where establishment productivity and size are affected by policy distortions. We solve the...

We study misallocation and sectoral productivity in a heterogeneous firms model with generalized production. Different from neo-classical models of production, our model endogenizes production-techniques and introduces firm-specific technique-distortions alongside factor- and scale-dependent...

We use machine learning to study how venture capitalists (VCs) make investment decisions. Using a large administrative dataset on French entrepreneurs that covers VC-backed as well as non-VC-backed firms, we use algorithmic predictions of new ventures' success to uncover potential sources of...
