The key question in multi-dimensional screening problems is how prices, incentives, or marginal tax rates in one economic activity should vary with other activities. We develop a theory of tax reforms in a setting with multidimensional heterogeneity amongst agents who take two economic...

We study optimal taxation in economies with general equilibrium market clearing, where agents with privately known labor skills and entrepreneurial abilities choose between deterministic labor income and risky firm operation. The government observes labor income and realized dividends but not...

The key question in multi-dimensional screening problems is how prices, incentives, or marginal tax rates in one economic activity should vary with other activities. We develop a theory of tax reforms in a setting with multidimensional heterogeneity amongst agents who take two economic...

This study characterizes optimal policy in an endogenous growth model where heterogeneous individuals choose between entering the workforce as unskilled labor or pursuing education to become skilled. In the decentralized economy, monopolists produce goods using both labor types. They purchase...

Abstract We study life expectancy inequality in a Mirrleesian life-cycle framework. Life expectancy shapes the efficiency dimension of redistribution via the pension wedge. Moreover, cost- and preference-based channels arising from the income-lifespan gradient reduce the mechanical value of...

We study the optimal taxation of corporate and dividend income when entrepreneurs can use retained earnings to reduce their tax burden. We show that eliminating dividend taxes while increasing the corporate income tax (CIT) to keep investment unchanged raises total tax revenue. Our simulations...

We study how Americans trade off the welfare of the poor versus the rich using incentivized transfer experiments. Combining this with estimates of the Elasticity of Taxable Income, we quantify optimal income tax rates in the US. Revealed preferences show strong concern for the poor across the...

We use variation in marginal tax rates and in tax bracket thresholds at which they apply in order to identify the substitution and income effects of tax reforms. We use a triple-difference estimator that exploits variation from subnational tax reforms, for which behavioral responses to taxes are...

Joint taxation of married couples represents a puzzle for welfare economics. We investigate whether political economy forces can explain its persistence. We develop sufficient statistics to determine whether a reform towards individual taxation would garner majority support and apply this...

The conventional wisdom is that a big jurisdiction sets a higher tax rate than a small jurisdiction. We show this result arises due to simplifying assumptions that imply tax-base sensitivities are equal across jurisdictions. When more than two jurisdictions compete in commodity taxes, tax-base...

Frank Ramsey is often portrayed as a British thinker immersed in theoretical problems in philosophy, mathematics, and economics. However, as Cheryl Misak (2020) shows, he was also preoccupied with political problems and concerned with practical efforts to improve the world. This chapter focuses...

I take a simple model of affine taxation of labour income and append to it the possibility that the chosen tax schedule triggers conflict in society. I demonstrate theoretically that, under certain conditions, the set of efficient tax schedules is a proper subset of the set of efficient tax...

The conventional wisdom is that a big jurisdiction sets a higher tax rate than a small jurisdiction. We show this result arises due to simplifying assumptions that imply tax-base sensitivities are equal across jurisdictions. When more than two jurisdictions compete in commodity taxes, tax-base...

Using surveys and experiments, we provide evidence on how people think about and justify sugar-sweetened-beverage (SSB) taxes, a widely discussed behavioral policy intervention. We show that motives to correct internalities and behavioral biases impact policy preferences almost as much as...

This paper studies the optimal design of differentiated consumption taxes in the presence of progressive labor income taxes and capital income taxation. A quantitative heterogeneousagent model with non-homothetic preferences and uninsurable idiosyncratic risk is estimated using US consumption...

Over the last decades, the United States has experienced a large increase in, both, income inequality and living standards. The workhorse models of optimal income taxation call for more redistribution as inequality rises. By contrast, living standards play no role for taxes and transfers in...

This paper explores whether tax compliance would be affected if the tax payers are "status" seekers. If relative income is a symbol of relative status in a society, status concerned individuals would evade paying taxes more relative to the case where status is not a concern. However, such an...

This paper incorporates labor market inactivity and long-term unemployment into the framework of optimal redistributive taxation. We examine how a combination of education policy, public employment programs, unemployment benefits, and optimal income taxation can effectively address both...

We study optimal redistribution and carbon taxation in a Mirrlees framework. Households differ in their carbon footprint due to both (i) the overall level of spending and (ii) the composition of spending. Introducing a cap on carbon emissions reduces the social value of output, which lowers the...

We examine the role of government investment in defense capital as a deterrence tool. Using an optimal fiscal policy framework with endogenous disaster risk, we allow for an endogenous determination of geopolitical risk and defense capacity, which we discipline using the Geopolitical Risk Index....

We analyze the optimal nonlinear income tax schedule for taxpayers with multiple incomes and multiple unobserved characteristics. We identify smoothness assumptions and extensions of the single crossing conditions that enable the characterization of the optimum through variational calculus. Both...

Raising the retirement age is a common policy response when social security schemes face fiscal pressures. We develop and estimate a dynamic life cycle model to study optimal retirement and tax policy when individuals face health shocks and income risk and make endogenous retirement decisions....

We study optimal housing taxation in a Mirrleesian framework where individuals differ in both labor productivity and land ownership. Housing services are produced by combining scarce land with structures that require maintenance, which can be performed either in-house or through market...
