This paper investigates how tax rates and tax enforcement jointly impact fiscal capacity in low-income countries. We study a policy experiment in the D.R. Congo that randomly assigned 38,028 property owners to the status quo tax rate or to a rate reduction. This variation in tax liabilities...

German municipalities levy local business taxes by choosing a tax rate to apply to local business income, where the tax base is defined uniformly at the national level. Before the federal government's imposition of a minimum tax rate in 2004, some municipalities such as the tiny North Sea town...

Empirical research in public economics, including our own, often uses variation in state and local taxes as an empirical laboratory to estimate causal relationships. A key concern is that other taxes might change at the same time. To assess this concern, we develop a dataset of state (1977-2022)...

The share of pre-tax income flowing to the top of the UK income distribution increased continually and substantially in the three decades leading up to the financial crisis, but has changed little since 2013. Using microdata sampled from UK tax records, we describe the nature of top incomes in...

In the second half of the 2010s more than 100 countries--including all large offshore financial centers--started to automatically exchange bank information with foreign tax authorities. This informational big-bang marks a break with the situation of offshore bank secrecy that prevailed before....

The philanthropic sector is highly consequential, particularly in the United States, and the most important policies directed toward this sector are tax policies. Yet most economic analysis of the optimal tax treatment of charitable giving is ad hoc, treating it as a subject unto itself. This...

This article explores subjects in optimal income taxation characterized by recent research interest, practical importance in light of concerns about inequality, potential for misunderstanding, and prospects for advancement. Throughout, the analysis highlights paths for further investigation....

A common feature of federal systems is that tax bases are joint property. Consequently, state and federal tax setting decisions are interdependent. Our aim here is to put forward a rudimentary theoretical analysis of this phenomenon, and to use the theory as a framework for econometrically...

Property taxes in developing countries are plagued by noncompliance and can exacerbate liquidity constraints. We characterize optimal enforcement and taxation policies as functions of revenue elasticities and measures of taxpayer hardship. We estimate these parameters using multiple sources of...

How has globalization affected the relative taxation of labor and capital, and why? To address this question we build and analyze a new database of effective macroeconomic tax rates covering 150 countries since 1965, constructed by combining national accounts data with government revenue...
