Swedish wives' market earnings contribute 39% of the net family earnings of couples living together. German wives contribute 12%. This paper employs Swedish and German micro data on earnings and personal characteristics of couples. After tax earnings are simulated, under both the tax system of...

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 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...

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...

We analyze the joint dynamics of religious beliefs, scientific progress and coalitional politics along both religious and economic lines. History offers many examples of the recurring tensions between science and organized religion, but as part of the paper’s motivating evidence we also...

To what extent has Sub-Saharan Africa’s slow economic growth over the past five decades been due to price and trade policies that have discouraged production of agricultural relative to non-agricultural tradables? This paper uses a new set of estimates of policy distortions to relative prices...

We model technological and financial innovation as reflecting the decisions of profit maximizing agents and explore the implications for economic growth. We start with a Schumpeterian endogenous growth model where entrepreneurs earn monopoly profits by inventing better goods and financiers arise...
