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 synthesizes and extends the literature on the taxation of foreign source income in a framework that covers both greenfield and acquisition investment, and a general constraint linking investment at home and abroad for the multinational by introducing a cost of adjustment for the...

This paper provides a simple political agency model to explain the effect of political alignment between different tiers of government on intergovernmental grants and election outcomes. Key features of the model are: (i) rational voters interpret public good provision as a signal of incumbent...

We investigate whether private information about citizens' competence in political office can be revealed by their entry and campaign expenditure decisions. We find that this depends on whether voters and candidates have common or conflicting interests; only in the former case can entry be...

This paper studies a principal-agent model of the relationship between an incumbent officeholder and the electorate, where the officeholder is initially uninformed about her ability. If officeholder effort and ability interact in the production function that determines performance in office,...

Economists typically check the robustness of their results by comparing them across plausible ranges of parameter values and model structures. A preferable approach to robustness--for the purposes of policymaking and evaluation--is to design policy that takes these ranges into account. We modify...
