Total fertility rates in Sub-Saharan Africa are nearly double that of any other region in the world. Evidence is mixed on whether providing contraceptives has an impact on fertility. I exploit exogenous, intermittent reductions in contraceptive supply in Ghana, which resulted from targeted cuts in U.S. funding, to examine impacts on pregnancy, abortion, and births. Women are unable to compensat...
Recent reports suggest that infection with Campylobacter jejuni, a common enteric pathogen, may cause Guillain-Barré syndrome (GBS) by triggering demyelination of peripheral nerves. GBS is preceded by an acute infectious illness (due to a variety of agents) in 50%-75% of cases; the onset of neurological symptoms is preceded by diarrhea in 10%-30% of cases. In the last decade, more than 20 publi...
We explore the relation between international financial integration and the level of entrepreneurial activity in a country. Using a unique data set of approximately 24 million firms in nearly 100 countries in 1999 and 2004, we find suggestive evidence that international financial integration has been associated with higher levels of entrepreneurial activity. Our results are robust to using vari...
Deleted in colorectal cancer (DCC) is a candidate tumor-suppressor gene located at chromosome 18q21. However, DCC gene was found to have few somatic mutations and the heterozygous mice (DCC(+/-)) showed a similar frequency of tumor formation compared with the wild-type mice (DCC(+/+)). Recently, DCC came back to the spotlight as a better understating of its function and relationship with its li...
We explore the relation between international financial integration and the level of entrepreneurial activity in a country. Researchers have stressed the role of new firm activity and economic dynamism on growth. Yet, the empirical effects of international capital mobility on entrepreneurial activity have received little attention in the literature albeit the ambiguous theoretical predictions a...
Special and differential treatment (S&D) for developing countries continues to be a defining feature of the multilateral trading system. This paper seeks to address key aspects of what has become an increasingly entangled and multi-faceted discussion. The paper begins by reviewing the historical context in which the relationship of developing countries with the multilateral trading system evolv...
A total of 221 strains of Aeromonas species isolated in Mexico from clinical (161), environmental (40), and food (20) samples were identified using the automated system bioMérieux-Vitek. Antisera for serogroups O1 to 044 were tested using the Shimada and Sakazaki scheme. The K1 antigen was examined using as antiserum the O7:K1C of Escherichia coli. Besides, we studied the antimicrobial patterns...
A large body of literature has arisen in economics and political science analyzing the apparent “resource curse”—the tendency of countries with high levels of natural resources to exhibit worse economic and political outcomes. The author examines the purported causal mechanisms underlying this “curse” and shows that they all center on the revenue that these resources generate for the government...
