This paper investigates how the mode of entry into a foreign market can be influenced by the intensity of R&D in an industry and the protection of intellectual property rights (IPR) in a recipient country. It then analyzes the link between the IPR regime and policies that place limits on the...

This paper uses survey data from 13 countries to document the economic lives of the poor (those living on less than $2 dollar per day per capita at purchasing power parity) or the extremely poor (those living on less than $1 dollar per day). We describe their patterns of consumption and income...

The paper surveys the interactions between aid and trade, distinguishing between policies and outcomes as well as between various instruments. It first discusses the theoretical literature, focusing on the causal impact of aid on the recipient’s welfare via the trade channel, before turning to...

This paper is a practical guide (a toolkit) for researchers, students and practitioners wishing to introduce randomization as part of a research design in the field. It first covers the rationale for the use of randomization, as a solution to selection bias and a partial solution to publication...

We report on an on-going project, which asks a number of questions relevant to the study of state capacity. What are the main economic and political determinants of the state’s capacity to raise revenue and support private markets? How do risks of violent conflict affect the incentives to...

Because of concern that OECD tariff reductions will translate into worsening export performance for the least developed countries, trade preferences have proven a stumbling block to developing country support for multilateral liberalization. We examine the actual scope for preference erosion,...

Government policies have helped nurture domestic capabilities in consumer electronics and other advanced areas that would most likely not have developed in their absence. As a result, China...

This paper models how migration both influences and responds to differences in disease prevalence between cities, regions and countries, and show how the possibility of migration away from high-prevalence areas affects long-run steady state disease prevalence. We develop a dynamic framework...

Why do soft budget constraints exist and persist? In this paper we argue that the prevalence of soft budget constraints can be best explained by the political desirability of softness. We develop a political economy model where politicians cannot commit to policies that are not ex post optimal....

Economies at early stages of development are often shaken by abrupt changes in growth rates, whereas in advanced economies growth rates tend to be relatively stable. To explain this pattern, we propose a theory of technological diversification. Production makes use of different input varieties,...
