The management of the exchange rate is possible only if the government pursues a monetary-fiscal policy mix which is consistent with its exchange rate targets. In this paper with uncertainty concerning the length of individual life the real consequences of exchange rate management depend on the...

We introduce firm and worker heterogeneity into a model of innovation-driven endogenous growth. Individuals who differ in ability sort into either a research sector or a manufacturing sector that produces differentiated goods. Each research project generates a new variety of the differentiated...

In this paper, we examine one channel through which the trade regime might affect growth in the long run. We model endogenous technological progress that results from profit maximizing investments by far-sighted entrepreneurs. Productivity in the research lab depends upon the "stock of knowledge...

Price controls were part of Israel's stabilization program of July 1985. Some results of the program seem to be inconsistent with competitive macroeconomic models. It is suggested that these results are consistent with an economy that has an oligopolistic market structure. The paper explores the...

We develop a model of growth driven by successive improvements in 'General Purpose Technologies' (GPT's), such as the steam engine, electricity, or micro-electronics. Each new generation of GPT's prompts investments in complementary inputs, and impacts the economy after enough such compatible...

We examine the extent to which developing countries that do little, if any research and development themselves benefit from R&D that is performed in the industrial countries. By trading with an industrial country that has large 'stocks of knowledge' from its cumulative R&D activities, a...

We develop a simple model of international trade with heterogeneous firms that is consistent with a number of stylized features of the data. In particular, the model predicts positive as well as zero trade flows across pairs of countries, and it allows the number of exporting firms to vary...

Polities differ in the extent to which political parties can pre-commit to carry out promised policy actions if they take power. Commitment problems may arise due to a divergence between the ex ante incentives facing national parties that seek to capture control of the legislature and the ex...

We study the determinants of the extent of outsourcing and of direct foreign investment in an industry in which producers need specialized components. Potential suppliers must make a relationship-specific investment in order to serve each prospective customer. Such investments are governed by...

We examine integration strategies of multinational firms that face a rich array of choices of international organization. Each firm in an industry must provide headquarter services from its home country, produce intermediate inputs, and assemble the intermediate goods into final products. Both...
