This testimony makes three main points. First, income volatility, especially when it involves income declines, imposes significant hardships on American families. It heightens stress about finances and may increase household living expenses. These hardships are most pronounced for middle-and...

We show that the optimal property tax rate rises with the ratio of land rents to structure and land development costs. California's high ratio of income to property tax revenue and the distribution of Federal housing subsidies thus appear geographically misplaced. Proportional taxation of...

Almost all theoretical work on how to calculate the marginal deadweight loss has been done for linear taxes and for variations in linear budget constraints. This is quite surprising since most income tax systems are nonlinear, generating nonlinear budget constraints. Instead of developing the...

Pension benefit rules depend on individual history far more than taxes do, and age plays a much larger role in pension determination than in tax determination. Apart from some simulation studies, theoretical studies of optimal tax design typically contain neither a mandatory pension system nor...

Whether observed differences in redistributive policies across countries are the result of differences in social preferences or efficiency constraints is an important question that paves the debate about the optimality of welfare regimes. To shed new light on this question, we estimate labor...

Concurrent taxation is a feature of many federal systems. As a consequence of this fact, the tax policy of one level of government affects the tax base of the other. This paper carries out a theoretical analysis of the interdependent tax-setting decisions of federal and regional governments,...

This paper computes the optimal progressivity of the income tax code in a dynamic general equilibrium model with household heterogeneity in which uninsurable labor productivity risk gives rise to a nontrivial income and wealth distribution. A progressive tax system serves as a partial substitute...

A model is presented for simulating the tax burden on highly skilled manpower. The effective average tax rate, defined as the relative wedge between employment costs and disposable income, is computed. Income and payroll taxes and social security contributions not yielding an equivalent benefit...

This paper characterizes optimal income taxation when individuals respond along both the intensive and extensive margins. Individuals are heterogeneous across two dimensions: specifically, their skill and disutility of participation. Preferences over consumption and work effort can differ with...
