European countries do less research than Japan and the United States. We use a quantitative multi-country growth model to ask: (i) Why is this so? (ii) Would there be any benefit to expanding research in Europe? (iii) What would various European research promotion policies do? We find that (i)...

Innovative activity is highly concentrated in a handful of advanced countries. These same countries are also the major exporters of capital goods to the rest of the world. We develop a model of trade in capital goods to assess its role spreading the benefits of technological advances. Applying...

Global environmental concerns have increased the sensitivity of governments and other parties to the actions of those outside their national jurisdiction. Parties have tried to extend influence extraterritorially both by promising to reward desired behavior and by threatening to punish undesired...

Most contributions to optimal tax theory have assumed that all prices, including that of leisure, are known with certainty. The purpose of this paper is to analyze optimal taxation when workers have imperfect information about their wages at the time they choose their labor supplies. Both...

Foreign portfolio investment is threatened by the risk of default and repudiation, while direct foreign investment is threatened by the risk of expropriation. These two contractual forms of investment can differ substantially in: (1) the amount of capital they can transfer from abroad to...

In a dynamic economy land and capital serve not only as factors of production but as assets which individuals use to transfer income from workinq periods to retirement. Static models of international trade based on the specific-factors model incorporate only the first of these. Once the second...

We develop a simple model of the choice between exploiting a technology in another country via export and via direct foreign investment. The model points to the destination country's size, level of technological sophistication, and distance from the source as factors in the decision. Moreover,...

We examine the sales of French manufacturing firms in 113 destinations, including France itself. Several regularities stand out: (1) the number of French firms selling to a market, relative to French market share, increases systematically with market size; (2) sales distributions are very similar...

We model the invention of new technologies and their diffusion across countries. Our model predicts that, eventually, all countries will grow at the same rate, with each country's productivity ranking determined by how rapidly it adopts inventions. The common growth rate depends on research...

In this paper we examine the factors affecting the structure of executives' compensation packages. We focus particularly on the role of various types of delayed compensation as means of "bonding" executives to their firms. The basic problem is to design a compensation package that rewards...
