When firms engaged in R&D are observably heterogeneous (in size) and policymakers are able to condition policy on the observed heterogeneity, what is the optimal policy? This paper starts with a static two-stage duopoly model of R&D competition with uncertainty and finds it welfare enhancing to...

We introduce a model of an infinitely-lived nonprofit organization facing donor crowd-out by government grants and credit constraints. The nonprofit chooses the optimal allocation of resources over time between providing service and fund-raising activities. We show that the response of...

Gibrat's Law of proportionate effect, as applied to firms, states that the growth rate of a firm is independent of its size. Empirical work on firm dynamics finds crucial deviations from Gibrat's Law such as smaller firms growing faster than larger firms (Evans, 1987, and Hall, 1987), a negative...

The United States introduced Federal Trade Adjustment Assistance (TAA) as part of the 1962 Trade Expansion Act to dampen the adverse impact of increased trade on workers. Applications to receive TAA require approval from the Department of Labor. Guided by the technical criteria used by the U.S....

Nonprofits are increasingly present in industries with a large for-profit sector, raising questions about their competitive advantage afforded by the nonprofit tax exemption. We estimate an equilibrium model of market structure for recreation/fitness centers to assess whether nonprofit and...

An enduring challenge that policy makers in open economies confront is the choice between three desirable, yet jointly unattainable objectives of maintaining a fixed exchange rate regime, free international capital flows and monetary policy independence. This paper examines these three tenets of...

We analyze a class of linear regression models including interactions of endogenous regressors and exogenous covariates. We show that, under typical conditions regarding higher-order dependencies between endogenous and exogenous regressors, the OLS estimator of the coefficient of the interaction...

In the classic Meltzer and Richard (1981) model, the canonical model of income redistribution in democracies, voters, heterogeneous on the sole dimension of idiosyncratic productivity,evaluate an income redistributive program that pays everyone a lump-sum income subsidy financed by a distorting...
