Dual-regime business tax systems typically subject smaller firms to an output (turnover) tax and larger firms to a profit (corporate) tax. Despite their prevalence, there is little formal analysis of their optimal design. This paper addresses this gap by developing a theoretical framework to...

The paper analyses commodity taxation in an economy where a good can be recycled. Consumers deliver units of a used good to a reuse operator, who sells the good in a second-hand market after some processing. Two regimes are considered. One is a pure market setting where the reuse operator pays...

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....

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...

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...

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...

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...

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...

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...

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...

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 optimal capital income tax rate has been shown to be nonzero in overlapping generations (OLG) models, as it helps redistribute income between cohorts and individuals with different labor supply elasticities and individual productivities. We show in a medium-scale OLG model that the optimal...

This study examines optimal government redistribution in a Mirrleesian framework, accounting for a negative effect of longer working hours on productivity. A government ignoring this effect perceives labor supply as insufficient and sets lower marginal income taxes to encourage work. In...

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...

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...

This paper explores the Taxation system in the Republic of Kosovo. It researches the need and reasons for the optimal taxation system that the Republic of Kosovo should develop as part of the proposed Taxation reform (based on recommendation). The Republic of Kosovo is the newest country in...

How much does society value redistribution? The common method to derive inverse-optimum welfare weights is by inverting an optimal-tax model. Our alternative imposes fewer restrictions on labor supply and enables comparisons across household types. We use a structural labor supply model to...

We study the optimal taxation of expenditures that generate income while also serving a consumption function. We characterize the Pareto optimal income tax deduction for such mixed-purpose expenditures within a generalized Atkinson-Stiglitz model. Pareto optimality requires a partial deduction...

In practice, both pre- and after-tax performance measures are used to incentivize managers. In this paper, we analyze the optimality of these performance measures in an agency setting, assuming that both the principal and the agent face tax base risks. Switching from a pre-tax to an after-tax...
