This paper estimates the effects of tax incentives on charitable contributions in the UK, using the universe of self-assessment income tax returns between 2005 and 2013. We exploit variation from a large reform in 2010 to estimate intensive and extensive-margin tax-price elasticities of giving....

We propose a theory to explain why, and under what circumstances, a politician endogenously gives up rent and delegates policy tasks to an independent agency. Applied to monetary policy, this theory (i) formalizes the rationale for delegation highlighted by Alexander Hamilton, the first...

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 develop a conceptual framework which captures the effect of the VAT system on profit by two effective taxes. This allows (i) predictions of the determinants of voluntary registration and bunching at the registration threshold; (ii) develops a formula for estimating the elasticity of...

This paper considers the implications of an important cognitive bias in information processing, confirmation bias, in a political agency setting. In the baseline two-period case where only the politician’s actions are observable before the election, we show that when voters have this bias, it...

This paper studies the relationship between fiscal decentralization and electoral accountability, by analyzing how decentralization impacts upon incentive and selection effects, and thus on voter welfare. The model abstracts from features such as public good spillovers or economies of scale, so...

This paper considers the relationship between tax competition and growth in an endogenous growth model where there are stochastic shocks to productivity, and capital taxes fund a public good which may be for final consumption or an infrastructure input. Absent stochastic shocks, decentralized...

This paper considers the optimal taxation of savings intermediation and payment services in a dynamic general equilibrium setting, when the government can also use consumption and income taxes. When payment services are used in strict proportion to final consumption, and the cost of...

This paper revisits the fiscal decentralization theorem, by relaxing the role of the assumption that governments are benevolent, while retaining the assumption of policy uniformity. If instead, decisions are made by direct majority voting, (i) centralization can welfare-dominate decentralization...

Advocates of fiscal decentralization argue that amongst other benefits, it can increase the efficiency of delivery of government services. This paper is one of the first to evaluate this claim empirically by looking at the association between expenditure decentralization and the productive...
