More than 215 million people—approximately 3% of the world’s population—now live outside their country of birth (United Nations, 2009). Migration of individuals across international borders has socio-economic consequences both to the receiving and sending countries. One of the most important economic impacts of international migration is the amount of remittances sent home by migrants. World Bank (2011) estimated that developing countries received about $372 billion of remittances. Remittances serve as the second largest source of foreign reserves, next to exports of goods and services, for these countries. In addition, remittances benefit the poor households whose average income falls below the amount necessary to meet their most basic and non-food needs for the year.

This study focuses on the roles of international migration and remittances in the Philippines, which was ranked fourth in total international remittances received in 2009, after India, China, and Mexico (World Bank, 2012). The Philippine government refers to the temporary international workers or Overseas Filipino Workers (OFWs) as bagong bayani or new heroes. This epithet stems from the important roles that these migrant workers play: they often serve as the primary income providers for their families left in the Philippines, and their transfers are a source of foreign reserves for the Philippine economy.  

The colloquium presents evidence on three related research questions. The first is whether agricultural households in rural Philippines use remittances from OFWs, along with loans, and assets to mitigate the effect of negative shocks to their income. In particular, speaker Marjorie Pajaron will ask the question whether farmers depend on their network of family and friends when they encounter a natural disaster, like excessive rainfall or typhoon. The second is how migration affects the bargaining power within the household. Finally, she will discuss the remittance behavior of different types of migrants from the Philippines. 

Marjorie Pajaron joins the Walter H. Shorenstein Asia-Pacific Research Center during the 2012–13 academic year from the University of Hawai’i at Manoa Department of Economics where she served as a lecturer.

She took part for five years in the National Transfer Accounts project based in Honolulu. Her research focuses on the role of migrant remittances as a risk-coping mechanism, as well as the importance of bargaining power in the intra-household allocation of remittances in the Philippines. Pajaron received a PhD in economics from the University of Hawai’i at Manoa.

Providing people with safe drinking water is one of the most important health-related infrastructure programs in the world. The first part of our research investigates the effect of a major water quality improvement program in rural China on the health of adults and children. Using panel data covering about 4500 households from 1989 to 2006, we estimate the impact of introducing village-level access to water from water plants on various measures of health. The regression results imply that the illness incidence of adults decreased by 11 percent and their weight-for-height increased by 0.835 kg/m, and that children's weight-for-height and height itself both rose by 0.446 kg/m and 0.962 cm respectively, as a result of the program. And these estimates are quite stable across different robustness checks.

While the previous research has shown health benefit of safe drinking water program, we know little about the longer-term benefits such as education. The second part of our research examines the youth education benefits of this major drinking water infrastructure program. By employing a longitudinal dataset with around 12,000 individual observations aged between 16 and 25, we find that this health program has benefited their education substantially: increasing the grades of education completed by 0.9 years and their probabilities of graduating from a lower and upper middle schools by around 18 and 89 percent, respectively. These estimation results are robust to a host of robustness checks, such as controlling for educational policy and local resources (by including county-year fixed effects), village distance to schools, local labor market conditions, educational demand, instrumenting the water treatment dummy with topographic variables, among others. Our estimates suggest that this program is highly cost-effective.
