I survey the research on the last twenty-five years of subnational income tax policy and conclude that the defining feature of state and local income taxes is geography. Geographic boundaries limit the power of subnational governments to tax people and activities. The article discusses where...

Global tax governance has long struggled with ineffectiveness, as reflected in rising corporate tax avoidance that costs governments hundreds of billions of dollars annually. In response, the Organisation for Economic Cooperation and Development (OECD)/G20 advanced the most ambitious initiative...

This paper estimates the causal effect of income taxation on inter-provincial migration in Canada. We exploit a major tax decentralization reform between 1998-2001 that led to some provinces lowering their marginal and average tax rates more than others, particularly for top earners. Using a...

This paper analyses determinants of pass-through for Germany’s 2022 temporary fuel discount at its implementation and subsequent termination. Based on a unique dataset of fuel station characteristics and prices, we employ a two-stage Regression Discontinuity in Time (RDiT) methodology to...

In this paper we theoretically analyse the European Union's ongoing political impasse regarding the choice of a single method to allocate multinational enterprises' profits across countries and we find that this strategic situation resembles a coordination game with distributional consequences....

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 documents the rise of corporate tax-base narrowing measures in the EU using a novel dataset covering both tax rate and tax base reforms implemented between 2014 and 2022. Our findings indicate a shift away from the ’cut rate – broaden base’ approach, as governments increasingly...

This paper characterizes profit shifting behavior across the size distribution of multinational enterprises (MNEs) to evaluate the targeting of the recently introduced Global Minimum Tax (GMT). Using German microeconomic administrative data with no reporting gaps for tax havens, we first...

In recent decades, governments around the world have increasingly used various forms of state aid to try to attract and retain the business activity of foreign-owned multinational corporations. Yet, in most cases, this "commercialisation of state sovereignty" (Palan, 2002) has failed to catalyse...

This paper presents evidence of market externalities of tax evasion: firms' tax non-compliance distorts the outcomes of their competitors. Using novel administrative data on the universe of Italian firms, we compute a tax evasion proxy as the fraction of individual firms that manipulate their...

A broad empirical literature examines the impact of corporate taxes on firms' investment, location, and tax avoidance behaviour. Other corporate adjustment margins have received little attention. In this paper, we use administrative customs and tax return data from South Africa to demonstrate...

We study firm responses to local policies through a survey experiment, providing randomized information on the competitiveness of business tax rates and highway access in their headquarters' municipality. Firms often misperceive local policy competitiveness, especially for tax rates. Investment...

We study international migration responses of the super-rich to taxes using UK administrative data and a difference-in-differences design. We exploit a reform that removes access to a tax break on foreign income for foreigners based on their number of years in the UK, allowing us to compare...

This Perspective discusses the fiscal and economic impacts of the global minimum tax; currently being implemented by many countries around the world. The global minimum tax is expected to raise tax revenues, reduce profit-shifting, and allow jurisdictions to strike a better balance between...

The effective corporate tax rate is a critical measure reflecting a nation's fiscal policy and its attractiveness to foreign investment. This study investigates the relationship between macroeconomic determinants and effective corporate tax rates, focusing on Slovakia's competitiveness within...

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 documents new facts on corporate taxation and the revenue potential of corporate minimum taxes, leveraging firm-level tax returns from 16 countries. First, effective tax rates follow a humped-shaped pattern with firm size: small firms benefit from reduced rates, while large firms take...

We use a natural experiment and administrative data to study the effect of corporate tax cuts on business activity. For identification, we exploit the abolition of municipal corporate income taxation in Sweden in 1985, which created variation in corporate tax changes faced by different...

Digital Services Taxes (DSTs) and the OECD/G20 BEPS reforms are central pillars of current efforts to tax multinational digital platforms, yet their joint effects remain poorly understood. We develop a model of a platform that sells hardware to consumers and advertising to firms, with the two...

The aim of this study is to empirically investigate how financial globalization affects tax competition, focusing on implicit and effective tax rates across 29 European countries over the period 2010-2021. Our linear dynamic panel findings suggest that while financial globalization increases...

The purpose of this paper is to analyze the global minimum tax of 15% for international corporations, the fiscal impact of this policy which is already in force internationally as of January 1, 2025, as well as the determinants of corporate tax revenues, with a particular focus on the Western...
