摘要：Some public goods are provided entirely with private contributions, others with a mixture of public and private funding, and still others are entirely publicly funded. In order to study this variation, a model of dual provision is developed that endogenizes public and private funding. Households vote over an income tax that finances public supply of the good and on whether to permit private contributions. While permitting private contributions may lead to a reduction in total provision, a majo...

摘要：In the last few years, the city of New York has increased taxicab fares and relaxed a 59-year-old cap on the number of licenses. This article uses a dynamic equilibrium model of meeting frictions to quantify the impact of these policies on medallion prices and on the process that rules the meetings between passengers and taxicabs in New York City.

摘要：This article shows that the presence of incidental parameters in Baltagi and Griffin's (International Economic Review 29 (1988), 745-53) generalized error-components model implies there is no guarantee feasible and true GLS estimators have the same asymptotic distribution. The article then considers a related stratified error-components model that has no incidental parameters. In this model, unobserved heterogeneity occurs through variances changing across strata. The article provides an EM al...

摘要：I study the effect of worker heterogeneities on wages and unemployment in a directed search model. A worker's productivity in a given firm depends both on his type and on a worker-firm specific component. Firms advertise unconditional wage offers only. The resulting equilibrium is inefficient, with a too high wage premium for high-type workers, and too few high-type jobs. This reduces the welfare of high-type workers. My findings contrast with the findings in the literature on labor market seg...

摘要：Why are higher quality niches seen as intrinsically more profitable in business circles? Why do high quality products sometimes have a low real price, whereas it is unusual to see low quality products with high real prices? Can markets have quality differentiation as well as quality bunching? How does the rate at which fixed costs change with quality affect market structure? In this article we develop a new model of quality that casts light on such issues.

摘要：Should the government run fiscal deficits in response to an adverse external shock that warrants transfer of resources from production of nontraded to traded goods? This article considers normative fiscal policy implications of sectoral adjustment costs in a two-sector model with overlapping generations. Fiscal deficits benefit present generations by depleting foreign assets and slowing down the adjustment process. We show that despite no nominal rigidities, temporary fiscal deficits increase ...

摘要：We model demographic and economic long-run development in a setting where mortality is endogenous and subject to epidemic shocks. The model replicates the full transition from Malthusian stagnation to modern growth. Consistent with the historical facts, the economy also passes an intermediate post-Malthusian phase where growth rates of both population and per capita income increase simultaneously, as mortality rates fall and become less volatile. The escape from the Malthusian trap is the resu...
