The literature on research joint ventures (RJVs) has emphasized internalizing spillovers and cost-sharing as motives for RJV formation. In this paper we develop two additional explanations: product market complementarities and firm heterogeneity. We analyse a model of RJVs with asymmetric firms...

Convergence in per capita income across countries turns on whether technological knowledge spillovers are global or local in a large class of models. This Paper estimates the amount of spillovers from R&D expenditures in major industrialized countries on a geographic basis. A new data set is...

This paper compares adversarial with cooperative industrial and trade policies in a dynamic oligopoly game in which a home and foreign firm compete in R&D and output and, because of spillovers, each firm benefits from the other’s R&D. When the government can commit to an export subsidy, such a...

The literature on research joint ventures (RJVs) has emphasized internalizing spillovers and cost-sharing as motives for RJV formation. In this paper we develop an additional explanation: the incentive to exclude rivals in order to gain market power. We illustrate this effect in a simple model...

We study the relationship between geography and growth. To do so, we first develop a dynamic spatial growth theory with realistic geography. We characterize the model and its balanced growth path and propose a methodology to analyze equilibria with different levels of migration frictions. We...

The majority of microfinance impact studies focus on finding their effect on a specific group of beneficiaries, in contrast we aim to identify the impact on whole economies (economic growth, and financial sector development and reductions in income inequalities), which is an important policy...

We document a very large increase in agricultural productivity, peasants’ living standards, and industrial development in the 19th century Imperial Russia as a result of the abolition of serfdom. We construct a novel province-level panel dataset of development outcomes and conduct a...

This chapter describes how the spatial distribution of economic activity changes as economies develop and grow. We start with the relation between development and rural-urban migration. Moving beyond the coarse rural-urban distinction, we then focus on the continuum of locations in an economy...
