Using a quantitative model that features technical progress in automation and endogenous skill choice, we show that, given the current U.S. tax system, a sustained fall in automation costs can lead to a massive rise in income inequality. We characterize the optimal tax system in this model. We...

In theory, the U.S. tax system aims to attribute and tax all business income to individuals. But the tax treatment of this income varies. Pass-through income is taxed when earned; capital-gains income is taxed when realized; dividends when distributed; other forms of business income may escape...

We address this question in a heterogeneous-agent incomplete-markets model featuring exogenous idiosyncratic risk, endogenous skill investment, and flexible labor supply. The tax and transfer schedule is restricted to be log-linear in income, a good description of the US system. Rising...

This paper studies consumption and labor supply in a model where agents have partial insurance and face risk and initial heterogeneity in wages and preferences. Equilibrium allocations and variances and covariances of wages, hours and consumption are solved for analytically. We prove that all...

Immigration is often viewed as a proximate cause of the rising wage gap between high- and low-skilled workers. Nevertheless, there is controversy over the appropriate framework for measuring the presumed effect, and over the magnitudes involved. This paper offers an overview and synthesis of...

To what extent do different firms follow different wage policies? How do such policies affect worker mobility between firms, and what are the effects of different wage bargaining regimes? The empirical branch of personnel economics has long been hampered by a lack of representative data sets....

In recent decades, the US wage structure has been transformed by a rising college premium, a narrowing gender gap, and increasing persistent and transitory residual wage dispersion. This paper explores the implications of these changes for cross-sectional inequality in hours worked, earnings and...

Motivated by the unique experience of Israel of a supply-side shock of skilled migration, and the concurrent rise in disposable income inequality, this paper develops a model which can explain the mechanism through which a supply-side shock of skilled migration can reshape the political-economy...

This paper evaluates the tax reforms carried out in Sweden between 1980 and 1991. We use a recently developed nonparametric estimation technique to account for labor supply responses. We decompose the tax returns to study how the separate components influence hours of work, tax revenues...
