With increasing number of natural disasters, understanding the links between these events and child health has become timely and pertinent. Using a panel dataset, this paper empirically investigates the persistent effects on child health due to exposure to a series of natural disasters that occurred from 2002 to 2007 in Indonesia. We find that girls exposed to multiple disaster events are 0.19 standard deviations shorter and are 7 percent more likely to be stunted when measured 7 to 12 years later. We find no persistent effect on boys. From a public policy perspective, we highlight the need for coping strategies beyond access to credit or remittances in order to mitigate growth retardation in children.

SSRN Working Paper

In this paper, we go beyond traditional measures of cognitive abilities (IQ) in explaining labor market and social outcomes in developing countries. We exploit a rich dataset from Ghana that provides information on demographics, labor market outcomes, and a direct measure of cognitive ability along with other test scores to construct a measure of sustained attention. Our work is therefore related to the broader literature in Psychology on the importance of executive function on individual behavior and outcomes. We find that, at least for the case of Ghana, after controlling for IQ and other covariates, higher levels of sustained attention are associated with higher annual income, higher educational attainment, and a higher likelihood of being employed in a white collar job.

The Impact of Telecommunication Growth on the Service Sector: A Co-integration Analysis

Thamarapani, D. (2013) “The Impact of Telecommunication Growth on the Service Sector: a co integration analysis.” Journal of Management. 9(1). pp. 58-69.

Using annual time series data of Sri Lanka this study examines the impact of telecommunication sector growth on the service sector growth. The methodology employed consists of the bivariate and multivariate co integration approach to establish the long run equilibrium relationship and causality testing is employed to detect the direction of this relationship. The current study is the first of its kind to use annual secondary data to examine the long run relationship between telecommunications sector and service sector in Sri Lanka. I find statistical evidence for a positive long run equilibrium relationship between telecommunication sector growth and service sector growth which confirmed the research hypothesis. Finally, the possibility of one-way link between telecommunications sector growth and service sector growth was established through causality test. Based on these finding the current study emphasizes the need to target long term growth strategies in the telecommunication service sector for Sri Lanka.
