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....

This high-stakes experiment investigates the effect on buyers of mandatory disclosures concerning an insurance policy's value for money (the claims ratio) and the seller's commission. These information disclosures have virtually no effect despite most buyers claiming to value such information....

Can a bank increase its profit by subsidizing inactivity? This paper suggests this may occur, due to the presence of hidden information, in a monopolistic credit market. Rather than offering credit in a pooling contract, a monopolist bank can sort borrowers through an appropriate subsidy to...

Developing further the accumulating evidence that self-employment attracts optimists, this paper investigates the relationship between earnings and prior optimism. It finds that self-employed optimists earn less than self-employed realists. Amongst employees, optimists earn more. These results...

Extant evidence that the self-employed overestimate their returns by more than employees do is consistent with two mutually inclusive possibilities. Self-employment may generate optimism or optimists may be drawn to self-employment. This paper finds that employees who will be self-employed in...

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...

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...
