This paper considers a dynamic taxation problem when agents can allocate their time between working and investing in their human capital. Time investment in human capital, or "training," increases the wage and can interact with an agent's intrinsic, exogenous, and stochastic earnings ability. It...

This paper derives optimal income tax and human capital policies in a dynamic life cycle model of labor supply and risky human capital formation. The wage is a function of both stochastic, persistent, and exogenous "ability'' and endogenous human capital. Human capital is acquired throughout...

This paper considers dynamic optimal income, education, and bequest taxes in a Barro-Becker dynastic setup. Parents can transfer resources to their children in two ways: First, through education investments, which have heterogeneous and stochastic returns for children, and, second, through...

This paper reviews recent advances in the study of dynamic taxation, considering three main approaches: the dynamic Mirrlees, the parametric Ramsey, and the sufficient statistics approaches. In the first approach, agents' heterogeneous abilities to earn income are private information and evolve...

The relationship between the degree of inequality and the demand for redistribution has been a central question in political science and political economy. The famous median-voter model predicts that higher inequality, reflected in a growing gap between the income of the average and the median...

This paper summarizes the research on some of the major inequalities that have been exacerbated by the COVID-19 pandemic across OECD countries. It reviews findings related to inequalities across the income distribution, sectors and regions, gender, and inequalities in education inputs for...

I study how people understand, reason, and learn about tax policy. The goal is to uncover the mental models that people use to think about income and estate taxes. To that end, I run large-scale online surveys and experiments on representative U.S. samples to elicit not only respondents' factual...

I study how people understand and reason about trade and which factors shape their views on trade policy. I design and run large-scale surveys and experiments in the U.S. to elicit respondents' knowledge and understanding of trade. I also ask about their perceived economic gains and...

This paper studies the effect of corporate and personal taxes on innovation in the United States over the twentieth century. We use three new datasets: a panel of the universe of inventors who patent since 1920; a dataset of the employment, location and patents of firms active in R&D since 1921; and a...

We use a new dataset consisting of the universe of Greek corporate tax returns matched to financial statements to study a voluntary tax compliance program for small firms. This "self-assessment" program prescribed target taxable profit margins for different types of activity. Firms that reported...
