The paper analyses tax and tariff policy for trade between economies which each contain a monopolistically competitive industry producing differentiated products. The consequences of tax changes by a single country are examined, and the general desirability of taxing imports more heavily than...

We consider the impact of taxation when investors face a discrete choice between two or more mutually exclusive projects; in particular we consider the location choice of multinationals. Such choices depend on an effective average tax rate. We propose a precise measure of this rate, which is...

This paper sheds new light on why timing and entry mode should be considered simultaneously. We derive the profit levels at which it is optimal to switch from exporting to setting up a wholly owned subsidiary, creating a joint venture, or licensing production to a local firm. The preferred entry...

We develop a model of common agency with complete information and general preferences with non-transferable utility, and prove that the principals’ Nash equilibrium in truthful strategies implements an efficient action. We apply this theory to construct a positive model of public finance,...

We extend "economic equivalence" results, like the Ricardian equivalence proposition, to the political sphere where policy is chosen sequentially. We derive conditions under which a policy regime (summarizing admissible policy choices in every period) and a state are "politico-economically...

We develop a framework for optimal taxation when agents can earn their income both in traditional activities, where private and social products coincide, and in rent-seeking activities, where private returns exceed social returns either because they involve the capture of pre-existing rents or...

This paper surveys the evidence on the effectiveness of monetary transmission in developing countries. We summarize the arguments for expecting the bank lending channel to be the dominant means of monetary transmission in such countries, and present a simple model that suggests why this channel...

We suggest a development-compatible refunding system designed to mitigate climate change. Industrial countries pay an initial fee into a global fund. Each country chooses its national carbon tax. Part of the global fund is refunded to developing and industrial countries, in proportion to the...

This paper examines the relationship between openness and within-country regional inequality across 28 countries over the period 1975-2005. In particular, it tests a) whether increases in trade lead to rising inequalities, b) whether these inequalities recede in time, and c) whether increases in...

This paper assesses the effects of reducing tariffs under the Doha Round on market access for developing countries. It shows that for many developing countries, actual preferential access is less generous than it appears because of low product coverage or complex rules of origin. Thus lowering...
