This article reviews the state of the international trade literature on multinational firms. This literature addresses three main questions. First, why do some firms operate in more than one country while others do not? Second, what determines in which countries production facilities are...

We partnered with a micro‐lender in Mali to randomize credit offers at the village level. Then, in no- loan control villages, we gave cash grants to randomly selected households. These grants led to higher agricultural investments and profits, thus showing that liquidity constraints bind with...

Communism in East Germany sought to dampen the effect of market forces on firm productivity for nearly 40 years. How did East German firms respond to the free market after being thrust into it in 1990? We use a formal learning model and German business survey data to analyze the lasting impact...

This paper reports the results from a randomized evaluation of a microcredit program introduced in rural areas of Morocco starting in 2006 by Al Amana, the country's largest microfinance institution. Al Amana was the only MFI operating in the study areas during the evaluation period. Thirteen...

Many basic economic theories with perfectly functioning markets do not predict the existence of the vast number of microenterprises readily observed across the world. We put forward a model that illuminates why financial and managerial capital constraints may impede experimentation, and thus...

This paper reports on the first randomized evaluation of the impact of introducing the standard microcredit group-based lending product in a new market. In 2005, half of 104 slums in Hyderabad, India were randomly selected for opening of a branch of a particular microfinance institution...

The extensive empirical macro- and micro-level evidence on the impact of job security provisions is largely inconclusive. We argue that the weak evidence is a consequence of the weak power of statistics used, which is suggested by a dynamic theory of plant-level labor demand that we develop....

Nishimura et al. (2005) analyze the entry/exit behavior of Japanese firms during the 1990s and find that relatively efficient firms exited while relatively inefficient firms survived during the banking-crisis period of 1996-97. They conclude that the natural selection mechanism (NSM) apparently...

This paper studies optimal investment policies when the production function depends on capital of various vintages. In such an environment it is natural to ask whether the firm will invest in old-vintage capital at all. In this paper I derive such a condition. Predictably, investment in old...

This essay surveys the body of research that asks how the efficiency of corporate investment is influenced by problems of asymmetric information and agency. I organize the material around two basic questions. First, does the external capital market channel the right amount of money to each firm?...
