Mobile phones are transforming lives in low-income countries faster than ever imagined.  The effect is particularly dramatic in rural areas of sub-Saharan Africa, where mobile phones have often represented the first modern infrastructure of any kind.  The iconic image of cell phones in Africa is the market woman, surrounding by her goods while making calls to potential clients in the capital city.  Equally common are the slogans of mobile phone companies promising a better life for those who use it. 

Yet do these images and slogans reflect the reality of what cell phones can do?  Cell phones are being adopted by the rural and urban poor at a surprising rate, far exceeding cell phone companies' projections. An emerging body of research suggests that mobile phones are improving households' access to information and reducing costs, thereby making markets more efficient and increasing incomes.  These impacts have occurred without NGOs or donor investments - but as a positive externality from the IT sector.

Governments, donors and NGOs have noticed the potential of information technology in achieving development goals in a variety of sectors, including agriculture, education, health, financial services and governance.  Mobile phones can greatly facilitate the effectiveness of development programs, but are needed in partnership with the private sector. And while cell phone coverage reaches over 60% of the population in most African countries, other constraints to cell phone adoption - namely pricing and handset cost - should be addressed.

Jenny Aker has worked extensively in Central, North and West Africa for the past ten years for NGOs, international organizations and universities. Her research uses field work and field experiments to better understand field-driven development problems, primarily by teaming up with NGOs and program implementers in an effort to link research with policy and implementation.

Jenny is currently involved in three main areas of research. The first assesses the impact of information technology (mobile phones) on development outcomes, namely farmers’ and traders’ welfare, market performance, labor outcomes, literacy rates and early warning systems. Based upon her previous work in Niger, she is collaborating with Catholic Relief Services in Niger on Project ABC (Alphabétisation de Base par Cellulaire), which uses cell phones as a learning tool to allow literacy participants to read and write in their local languages via SMS. The project takes a rigorous impact evaluation approach, assessing the impact of cell phones on literacy rates and farmers’ marketing behavior. Her second area of research involves assessing the impact of climate change on farmer-herder conflicts in the Sahel, with a particular focus on Mali. Her third area of research evaluates the impact of specific development interventions -- including food aid distributions, local purchases, and cash vouchers – on producers’ welfare and market performance in the Sahel.

In September 2009, Jenny joined Tufts University as an Assistant Professor in the Economics Department and Fletcher School of Law and Diplomacy.

FrontlineSMS:Medic is a Palo Alto based tech nonprofit startup that began in early 2009 with several Stanford undergraduates and graduate students at the helm. The concept behind the group's software suite is simple: free intuitive mobile phone and computer applications built upon free and open source packages, such as OpenMRS and FrontlineSMS, to allow clinics and hospitals in the developing world to use mobile phones for healthcare services in resource poor settings. Their work has already broken rapidly out of their first pilot site in Malawi and now 2.2 million patients are being covered by their software in Uganda, Tanzania, Cameroon, Kenya, Burundi, Guatemala, Honduras, India and Bangladesh. Their service partners include Partners in Health, Clinton HIV/AIDS Initiative, and Village Health Works.

Paul Romer is a Senior Fellow in the Stanford Center for International Development (SCID) and the Stanford Institute for Economic Policy Research (SIEPR). His contributions to the field of economics include being the primary developer of New Growth Theory, which reduces the traditional emphasis on the scarcity of objects and directs attention to the power of new ideas. His theory has brought renewed optimism about the potential for growth in both advanced and developing economies.

For his work on the economics of ideas, Paul was named one of America's 25 most influential people by TIME magazine (1997), elected a fellow of the American Academy of Arts and Sciences (2000) and awarded the Horst Claus Recktenwald Prize in Economics (2002). He is a Research Associate of the National Bureau of Economic Research and a Fellow of the Econometric Society. Prior to his current Stanford University position, he taught in the university's Graduate School of Business as the STANCO 25 Professor of Economics and was honored with the Distinguished Teaching Award (1999). Before moving to Stanford, Paul taught economics at the University of California at Berkeley, the University of Chicago and the University of Rochester. He received his PhD in economics from the University of Chicago.

In addition to his career in teaching and research, Paul founded Aplia, Inc., which is now part of Cengage Learning. Aplia, which develops and applies technologies to improve student learning, grew out of Paul's conviction that it is possible to use information technology to raise productivity in education. This lesson has important implications for how societies keep up with the growing demand for highly educated workers-a demand that is driven by the use of new technology in all other sectors of the economy.

Scott Rozelle is the Helen F. Farnsworth Senior Fellow in the Freeman Spogli Institute for International Studies. Dr. Rozelle received his BS from the University of California, Berkeley; and his MS and PhD from Cornell University. Before arriving at Stanford, Rozelle was a professor at the University of California, Davis (1998-2000) and an assistant professor in the Food Research Institute and Department of Economics at Stanford University (1990-98). Currently, he is a member of the American Economics Association, the American Agricultural Economics Association, the International Association for Agricultural Economists, the Asian Studies Association, and the Association of Comparative Economics. He also serves on the editorial board of Economic Development and Cultural Change, Agricultural Economics, Contemporary Economic Policy, China Journal, and the China Economic Review.

Dr. Rozelle's research focuses almost exclusively on China and is concerned with three general themes: a) agricultural policy, including the supply, demand, and trade in agricultural projects; b) the emergence and evolution of markets and other economic institutions in the transition process and their implications for equity and efficiency; and c) the economics of poverty and inequality.

In the past several years, Dr. Rozelle's papers have been published in top academic journals, including Science, Nature, American Economic Review, and the Journal of Economic Literature. He is fluent in Chinese and has established a research program in which he has close working ties with several Chinese collaborators and policymakers. He is the chair of the International Advisory Board of the Center for Chinese Agricultural Policy; a co-director of the Agricultural Issues Center (University of California); and a member of Stanford's new Food, Security, and the Environment Program.

Weitseng Chen, a Fulbright scholar, will receive his JSD from Yale Law School in October 2007. His recent research focuses on China's foreign direct investment and property rights transition, the economic behaviors of ethnic foreign investors in China, and a China-Taiwan comparison on their rule of law transition. Prior to his Yale education, Chen practiced law in Taiwan in diverse fields such as Internet and information technology industry, the private sector and public interest affairs, governmental reforms, and international NGO affairs.

Weitseng Chen's recent publications include "East Asian Model and Rule of Law (with Randall Peerenboom, a to be published book chapter)", "WTO: Time's Up for Chinese Banks - China's Banking Reform and Non-Performing Loans Disposal" (Chicago Journal of International Law), "State, Market, and the Law: Law and Development in Taiwan" (Chinese) (Journal of the Humanities & Social Science), and a book titled Law and Economic Miracle: Interaction between Taiwan's Economic Development and Economic & Trade Laws after WWII.
