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...

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...

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...

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...

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...

Although economists widely advocate carbon pricing as an effective solution to reduce carbon emissions, this mechanism has had so far limited effects. This paper proposes a new type of tax to help finance (and accelerate) the green transition. A carbon wealth tax (CWT) is proposed to be levied...

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...

To evaluate the marginal welfare effects of taxation and of public spending, we must account for both distortionary and distributional effects. The distributional consequences of taxation, in terms of welfare, cannot be fully captured in in the measures currently used in the literature, such as...

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...

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...

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....

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 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 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...

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...
