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：A labor market model under search frictions is developed, where participants are heterogeneous in productivity and the decision of which type of agents to match with is endogenized. Two applications are studied. It is observed that countries with high (low) unemployment tend to exhibit low (high) wage dispersion. And there is evidence showing that individual and firm characteristics have more explanatory power for the French than for the American wage data. Matching patterns can account for th...

摘要：A CGE model is used to analyze the impact of public school financing on private school attendance. The common perception that public school finance centralization will necessarily lead to greater private school attendance is not correct in such a model-even when that centralization involves an extreme equalization as in California. Furthermore, if centralization is less dramatic (as in most states), declines in private school attendance are even more pronounced. This weakens the speculation th...

摘要：We study the infinite-horizon model of household portfolio choice under liquidity constraints and revisit the portfolio specialization puzzle. We show why the puzzle is robust to several model variations, and argue that positive correlation between earnings shocks and stock returns is unlikely to provide an empirically plausible resolution. We find that relatively small fixed costs for stock market entry are sufficient to deter stockholding because, for a plausible range of parameter values, h...

摘要：This article studies the role of risk sharing in dynamic credit relationships that are secured by physical collateral. It is shown that, when borrowers and lenders cannot commit not to terminate relationships (through default in the first case and liquidation in the second), overinvestment is optimal. Overinvestment facilitates risk sharing in this context: It occurs in expectation of periods in which lenders are unwilling to supply all the funds necessary to achieve complete risk sharing. Typ...

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：Mobility indices are popular tools designed to quantify the extent of income changes by aggregating local distributional change into a global scalar according to some rule. For some mobility measures, this aggregation rule is only implicit in their standard definition. We derive an insightful approximation to the (statistical) aggregation rule for the important class of mobility indices introduced by Shorrocks (Journal of Economic Theory 19 (1978), 376-93) and further generalized by Maasoumi a...

摘要：We model rotating savings and credit associations (Roscas) among risk-averse participants who experience privately observed income shocks. A random Rosca is not Advantageous, whereas a bidding Rosca is if temporal risk aversion is less pronounced than static risk aversion. The payoff scheme of a bidding Rosca facilitates risk sharing in the presence of information asymmetries. The risk-sharing performance of a simple arrangement where a group of homogenous individuals runs several bidding Rosc...
