We study episodes where economic growth decelerates to negative rates. While the majority of these episodes are of short duration, a substantial fraction last for a longer period of time than can be explained as the result of businesscycle dynamics. The duration, depth and associated output loss of these episodes differs dramatically across regions. We(More)
This paper argues that the capacity of financial markets to aggregate information is diminished in times of distress, resulting in countercyclical economic uncertainty. I build upon a rational expectations equilibrium model that delivers this result from the combination of (i) countercyclical funding constraints faced by informed financial intermediaries,(More)
A disproportionately large amount of the world's agronomic potential for the production of bioethanol is concentrated in a subset of developing countries. To develop that potential, countries need both the existence of an appropriate local business ecosystem and reliable global demand. The creation of a global market for green biofuels, however, is affected(More)
This paper studies technology adoption in a cluster of soccer-ball producers in Sialkot, Pakistan. We invented a new cutting technology that reduces waste of the primary raw material and gave the technology to a random subset of producers. Despite the arguably unambiguous net benefits of the technology for nearly all firms, after 15 months take-up remained(More)
a r t i c l e i n f o We study the micro dynamics of new exports from a country. The modern international trade workhorse models (e.g. Melitz, 2003) assume heterogeneous productivity and, implicitly, predict that the ex-post largest exporters in a new product would be the pioneers, since they can pay back exploration costs. However, using detailed data on(More)
This paper provides the first real-world evidence of Giffen behavior, i.e., upward sloping demand. Subsidizing the prices of dietary staples for extremely poor households in two provinces of China, we find strong evidence of Giffen behavior for rice in Hunan, and weaker evidence for wheat in Gansu. The data provide new insight into the consumption behavior(More)
For how long does cultural heritage persist? Do the culturally inherited values of immigrants dilute as generations pass? We answer these question by studying the relationship between revealed political behavior of immigrant families and the culture of the place where they migrated from, either one or many generations ago. Using surnames as indicators of(More)
Lack of coordination among agencies at project level and scarce promotion of contracts at micro-scale are critical gaps widely spread in many Latin American regions. We discuss some specific and feasible mechanisms: (i) alliances for rural development and (ii) contract promoters; that may play a catalytic role to deal with the mentioned problems. Based on a(More)
The University of Cape Town Karl Storz Head and Neck Surgery Fellowship is the only head and neck surgery fellowship in Sub-Saharan Africa. This article briefly describes this fellowship and outlines the experience and ongoing collaborative efforts of members of the American Academy of otolaryngology-head and neck surgery with graduates of this program who(More)
