Previous research on optimal R&D subsidies has focussed on the long run. This paper characterizes the optimal time path of R&D subsidization in a semi-endogenous growth model, by exploiting a recently developed numerical method. Starting from the steady state under current R&D subsidization in...

Based on well-known evidence on labor supply elasticities, several authors have concluded that women should be taxed at lower rates than men. We evaluate the quantitative implications of taxing women at a lower rate than men. Relative to the current system of taxation, setting a proportional tax...

This study designs a natural field experiment linked to a controlled laboratory experiment to examine the effectiveness of matching gifts and challenge gifts, two popular strategies used to secure a portion of the $200 billion annually given to charities. We find evidence that challenge gifts...

Much is known about private returns to education in the form of higher earnings. Less is known about social value, over and above the private, market value. Associations between education and socially-desirable outcomes are strong, but disentangling the effect of education from other causal...

We analyze the welfare cost of inflation in a model with cash-in-advance constraints and an endogenous distribution of establishments' productivities. Inflation distorts aggregate productivity through firm entry dynamics. The model is calibrated to the United States economy and the long-run...

Was the increase in income inequality in the US due to permanent shocks or merely to an increase in the variance of transitory shocks? The implications for consumption and welfare depend crucially on the answer to this question. We use CEX repeated cross-section data on consumption and income to...

Empirical analyses of the effects of public and private pensions on household saving impose strong assumptions in order to obtain a tractable empirical model: fixed retirement and pension claiming ages, no borrowing constraint, little or no uncertainty, and no institutional restrictions on...

How should we construct incidence indexes for children and parents in the case of public subsidies for home-care of the elderly? What is the nature of a fiscal incidence index on a budgetary basis versus a theoretically more satisfactory index that is welfare-based? Can we find budgetary based...

In this paper, we study gains and losses that accrue to natives because of immigration. The gain on the aggregated level is called the ?immigration surplus?, which can be seen as analogous to a consumer surplus. We derive changes in the earnings of native owners of production factors by...
