Vaccination is a critical tool, along with suppression and treatment, for controlling epidemics such as SARS-CoV-2. To maximize the impact of vaccination, doses should be allocated to the highest value targets, accounting for health and potential economic benefits. We examine what allocation...

This paper studies the effect of state-owned enterprises on resource misallocation. Using a unique dataset by matching millions of records of land transaction, administrative records of business registration, and night light intensity data, and adopting a novel causal identification strategy, we...

Complementing other efforts, the Biden Administration recently announced the purchase of 500 million rapid antigen self-tests, to help address ongoing issues with access to COVID-19 tests. A website, launched on Jan 18, 2022 (https://www.covidtests.gov) enables those wishing to receive tests to...

We analyze monetary policy in a New Keynesian model with heterogeneous firms and financial frictions. Firms differ in their productivity and net worth and face collateral constraints that cause capital misallocation. TFP endogenously depends on the time-varying distribution of firms. Although a...

Expert decisions often deviate from evidence-based guidelines. If experts are unaware of guidelines, dissemination may improve outcomes. If experts are aware of guidelines but continue to deviate, promoting stricter adherence has ambiguous effects on outcomes depending on whether experts have...

I study the firm-level dynamic response of a commodity-exporting economy to global cycles in commodity prices. To do so, I develop a heterogeneous-firms model that endogenizes declines in aggregate productivity through reallocation towards less productive firms. Within a given sector, commodity...

We revisit the classical object reallocation problem under strict preferences. When attention is constrained to the set of Pareto-efficient rules, it is known that TTC is the only rule that is strategyproof and individually-rational. We hence relax this constraint and consider pair-efficiency. A...

In this paper we develop a theory of how factors interact at the plant level. The theory has implications for: (1) the micro foundations for capital skill complementarity (2) the relationship between factor allocation and plant size and (3) the effects of trade and growth on the skill premium....

In majoritarian democracies, popular policies may not be inclusive, and inclusive policies may not be popular. This dilemma raises the crucial question of when it is possible to design a policy that is both inclusive and popular. We address this question in the context of vaccine allocation in a...

Stochastic geometry (SG) allows us to model and analyze unplanned small-cell base station (BS) deployments. SGbased studies use mainly the Universal frequency reuse (UFR) scheme in which all of the available spectrum is occupied by all of the BSs. Such an intense frequency allocation at the BSs...
