We document contemporaneous differences in the aggregate labor supply of married couples across 19 OECD countries. We quantify the contribution of international differences in non-linear labor income taxes and consumption taxes, as well as male and female wages, to the international differences...

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 and merits of this proposition. Relative to the current system of taxation, setting a proportional tax rate on...

This paper studies the effects of labour income taxation on growth in an OLG model where both formal schooling and child care enter the human capital production function as complements. We compare them with the effects obtained in a model where only formal schooling matters for skill formation....

We evaluate reforms to the U.S. tax system in a dynamic setup with heterogeneous married and single households, and with an operative extensive margin in labour supply. We restrict our model with observations on gender and skill premia, labour force participation of married females across skill...

This paper formulates a model to examine the effects of changes in tax-benefit policy on the behavior of divorced parents and the well-being of children in single-parent households. Noncustodial parents choose the level of a child support payment to transfer to custodians. These, in turn, decide...

What are the welfare effects of a policy that facilitates for insurance customers to privately and covertly learn about their accident risks? We endogenize the information structure in Stiglitz's classic monopoly insurance model. We first show that his results are robust: For a small information...

We study the political determination of the level of social long-term care insurance when voters also choose private insurance and saving amounts. Agents differ in income, probability of becoming dependent and of receiving family help. Social insurance redistributes across income and risk...

In a model where patients face budget constraints that make some treatments unaffordable, we ask which treatments should be covered by universal basic insurance and which by private voluntary insurance. We argue that both cost effectiveness and prevalence are important if the government wants to...

This paper introduces a tractable model of health insurance with both moral hazard and adverse selection. We show that government sponsored universal basic insurance should cover treatments with the biggest adverse selection problems. Treatments not covered by basic insurance can be covered on...

Consumers, when buying health insurance, do not know the exact value of each treatment that they buy coverage for. This leads them to overvalue some treatments and undervalue others. We show that the insurance market cannot correct these mistakes. This causes research labs to overinvest in...
