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...

This paper develops a comprehensive framework for analyzing the revenue, efficiency and social welfare implications of top income taxation. It generalizes the Saez (2001) formula for the optimal top tax rate by deriving analytical expressions for the Laffer curve and excess burden. Applied to...

We develop a theory of tax reforms for a setting with multi-dimensional heterogeneity amongst taxpayers and multiple economic decisions that are all subject to fixed and variable costs. The theorems in this paper provide a complete characterization of the conditions under which Pareto- or...

Taxation plays a crucial role in microeconomics, as it directly impacts individuals, businesses, and the overall functioning of markets. We will explore the principles, objectives, and effects of taxation in the context of microeconomics

We develop a theory of commodity taxation featuring imperfect competition along with love-of-variety preferences and endogenous firm entry and exit, and we derive new formulas for the efficiency and pass-through of specific and ad valorem taxes. These formulas unify existing canonical ones and...

When deciding on the social desirability of public investment, the cost of a project is sometimes adjusted by a factor known as the Marginal Cost of Public Funds (MCP F ), which captures the cost of raising public funds through distortionary taxation. However, there is no scholarly consensus on...

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...

Taxation based on identity has a long, often sordid history, and persists to this day, usually with some subtlety. It is a relatively tame cousin of the blatant, violent, and genocidal policies that have targeted people of certain religions, races, and genders for millennia. It is, nevertheless,...

This paper characterizes the equity-efficiency tradeoff of corporate taxation using a stylized model that draws on the corporate investment and tax incidence literatures. We derive optimal corporate tax formulas in terms of estimable reduced-form elasticities and welfare weights on workers and...

In a perfect market economy, the cost of raising another euro of tax revenue equals one. However, once distortionary taxes on goods and factors are introduced, the marginal cost of public funds, MCPF, typically deviates from one. Often it exceeds one, but one can also find cases where it falls...

"This book focuses on the income taxation of individuals. Most income tax laws that apply to individuals apply in the same manner to entities such as corporations, partnerships, and trusts. So, this book is a survey of the fundamentals of income taxation that applies to all taxpayers, but we...

A Theory of International Taxation combines qualitative and quantitative analyses to shed light on the shaping of the international tax regime (ITR) over the last century. It offers a theory of the ITR as the product of the strategic interaction between three small groups: international...

This paper provides general and empirically implementable sufficient statistics formulas for optimal nonlinear tax systems in the presence of across-income heterogeneity in preferences, inheritances, income-shifting capabilities, and other sources. We study unrestricted tax systems on income and...

The informal economy has grown considerably in Zimbabwe due to the extended economic and political crisis in the country. This growth of the informal sector has shrunk formal sector tax collections thereby prompting authorities to set sights on informal sector taxation as an option to enhance...

This paper provides general and empirically implementable sufficient statistics formulas for optimal nonlinear tax systems in the presence of across-income heterogeneity in preferences, inheritances, income-shifting capabilities, and other sources. We study unrestricted tax systems on income and...

We introduce a new theory for optimizing frictions that prevents agents from choosing the threshold where the slope (kink) or intercept (notch) of a constraint changes. By making these frictions a function of observables, we can estimate why agents do not report exactly at predicted thresholds....

This paper characterizes the shape of the Laffer curve for consumption tax analytically, considering (i) the functional form of utility and (ii) the use of tax revenue in a neoclassical general equilibrium model. The tax revenue curve for consumption tax cannot be hump-shaped if the utility...

Most analyses of optimal income taxation make restrictive technical assumptions on preferences (such as single-crossing) and only derive properties of welfare-maximizing tax schedules. Here, for an economy with any finite numbers of groups and commodities, Pareto efficient tax structures are...

The implications of a large public debt for the implementation of capital controls for an economy where tax revenue collection is costly are examined. Conditions are analyzed under which policymakers will resort to capital controls to reduce the cost of recycling domestic public debt. The...

We study optimal taxation in a model with endogenous financial frictions, risky investmentand occupational choice, where the distribution of wealth across entrepreneurs affects how efficiently capital is used. The planner chooses linear taxes on wealth, capital and labor income to maximize the...

I characterize the optimal linear commodity taxes when households differ in multiple characteristics, in presence of an optimal non-linear tax schedule on the households' labour incomes. The optimal distortions caused by a linear commodity tax are larger if, conditional on labour income, more...

We study optimal taxation in a model with endogenous financial frictions, risky investment and occupational choice, where the distribution of wealth across entrepreneurs affects how efficiently capital is used. The planner chooses linear taxes on wealth, capital and labor income to maximize the...

This paper highlights the significance of open-economy considerations in the analysis of tax reforms. It focuses on domestic and international consequences of revenue-neutral conversions between income and value-added tax systems. The principal conclusion of this investigation is that the...

General equilibrium models have recently been used to simulate the effects of many proposed tax changes. However, in modeling the effects of the government on the economy, these models have assumed for simplicity that marginal tax rates equal the observed average tax rates, and that marginal...

The traditional method of analyzing the distorting effects of the income tax greatly underestimates its total deadweight loss as well as the incremental deadweight loss of an increase in income tax rates. Deadweight losses are substantially greater than these conventional estimates because the...

The normative principle of benefit-based taxation has exerted substantial influence on many areas of public finance, but it has been largely set aside in the modern theoretical approach to optimal income taxation, where welfarist objectives dominate. A prerequisite for that gap to close is the...

This article discusses the potential benefits of utilizing critical tax theory to enhance traditional tax policy analysis. The article demonstrates that because traditional tax policy presumes that taxpayer income level is the only salient factor in tax equity analysis, it fails to consider any...

This paper provides general and empirically implementable sufficient statistics formulas for optimal nonlinear tax systems in the presence of across-income heterogeneity in preferences, inheritances, income-shifting capabilities, and other sources. We study unrestricted tax systems on income and...

We characterize optimal policies in a multidimensional nonlinear taxation model with bunching. We develop an empirically relevant model with cognitive and manual skills, firm heterogeneity, and labor market sorting. The analysis of optimal policy is based on two main results. We first derive an...

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...

Standard optimal capital tax theory abstracts from modeling asset prices, making it unsuitable for thinking about capital gains and wealth taxation. We study optimal redistributive taxation in an environment with asset price changes, adopting the modern finance view that asset prices fluctuate...
