Personal Website | CV

I am a microeconomic theorist with research interests in the areas of industrial organization, information economics, natural resources, international trade and economic growth.

One strand of my research focuses on economic incentives under incomplete information; problems studied include dynamic trading under asymmetric information, signaling and strategic communication of private information in oligopolies, and dynamic charitable fundraising under incomplete information.

A second strand of research focuses on dynamic incentives and resource allocation over time; in particular, I have worked on problems of sustaining positive consumption under uncertainty, economic growth in the presence of technological non-convexities, extinction and conservation of renewable resources, control of invasive species, deforestation and the dynamics of industry structure and technological change.

I have also worked on issues related to strategic trade policy and trade agreements.

My current research topics include the effect of risk aversion on convergence to positive steady state in a model of stochastic growth, the effect of global trade negotiations on regional trade agreements, the effect of disclosure regulation on strategic information acquisition and the role of advertising when firms can engage in costly misinformation.

I grew up in the state of Assam in north eastern India. I studied at the University of Delhi, and then at Cornell University (Ithaca, NY) from where I received my doctorate. I taught at Erasmus University (Rotterdam, The Netherlands) and Florida International University (Miami, FL) before joining SMU in 2003. I served as Director of Graduate Studies in Economics from 2006 to 2014 and currently serve as Department Chair. In 2013-14, I served as President of the Faculty Senate and a member of the SMU Board of Trustees.
