In this paper we argue that very high marginal labor income tax rates are an effective tool for social insurance even when households have preferences with high labor supply elasticity, make dynamic savings decisions, and policies have general equilibrium effects. To make this point we construct...

We analyze the macroeconomic implications of increasing the top marginal income tax rate using a dynamic general equilibrium framework with heterogeneous agents and a fiscal structure resembling the actual U.S. tax system. The wealth and income distributions generated by our model replicate the...

This paper studies the effects of income taxation on entrepreneurship, empirically and in a structural macro model with entrepreneurial choice. Combining state-level tax data with household and firm data we document that higher and more progressive taxation has a strong negative impact on...

We study the optimal design of means-tested transfers and progressive income taxes. In a simple analytical model, we demonstrate an optimally negative relation between transfers and income-tax progressivity due to efficiency and redistribution concerns. In a rich dynamic model, we quantify 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...

In recent years, both academics and public commentators have alleged that "income inequality" is increasing in the United States. These commentators typically cite federal income tax return data to support their claims. However, studies based on tax return data provide highly misleading...

The employee dispatched by her company to work temporarily in international destinations is not a new phenomenon, but social structures between which the worker may move have arguably never been more complex. In a world of social insurance programs that feature broad contribution requirements...

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...

This testimony makes three main points. First, inheritances tend to exacerbate existing economic disparities and may be the most important barrier to intergenerational economic mobility. These tendencies are most pronounced at the top of the income distribution. While inherited income is...
