Can Higher Prices Stimulate Product Use? Evidence from a Field Experiment in Zambia

Ashraf, Nava, James Berry, and Jesse M. Shapiro
October 2009

The controversy over whether and how much to charge for health products in the developing world rests, in part, on whether higher prices can increase use, either by targeting distribution to high-use households (a screening effect), or by stimulating use psychologically through a sunk-cost effect. We develop a methodology for separating these two effects. We implement the methodology in a field experiment in Zambia using door-to-door marketing of a home water purification solution. We find that higher prices screen out those who use the product less. By contrast, we find no consistent evidence of sunk-cost effects.

Sovereign Wealth in Abu Dhabi

Rawi, Abdelai
May 2009

By the turn of the century, oil had already made the tiny emirate of Abu Dhabi rich beyond anyone's wildest dreams. A sovereign wealth fund, the Abu Dhabi Investment Authority (ADIA), has invested extra oil revenues abroad for more than thirty years and amassed a still-growing portfolio worth approximately $750-900 billion. ADIA is widely believed to be the world's largest sovereign wealth fund-indeed the world's largest institutional investor. But Abu Dhabi is not yet a "developed" economy. So, in 2002, the Mubadala Development Company was established as a government-owned investment vehicle. Unlike ADIA's mandate to build and manage a financial portfolio, Mubadala's charge was to develop Abu Dhabi. According to some observers, ADIA was a "sovereign savings fund," while Mubadala was a government-owned investment firm. Mubadala is supposed to invest the wealth of the emirate in activities that would diversify the economy away from energy and into industry and services. Although each Mubadala investment is supposed to earn large returns, the strategy balances financial against "strategic" returns. ADIA and Mubadala are the institutional architecture to manage the wealth of the Abu Dhabi sovereign.

Putting Patients First: Social Marketing Strategies for Treating HIV in Developing Nations

Chance, Zoe, and Rohit Deshpandé
April 2009

It is more than mere coincidence that the highest rates of HIV occur in the world's poorest countries. Of the over 40 million people currently living with HIV, 95 percent are in the developing world. The first part of this paper explores the economics of HIV and treatment from a social marketing perspective. The second part of the paper uses three specific case histories of successful social marketing organizations in Africa, Asia, and South America to inductively generate a consumer (patient)-centric marketing model. The focal organizations are unique in that they all identify patient needs first, then work backwards to develop economically viable solutions. These solutions are not without flaws, and the future of these programs remains uncertain, but we hope that illuminating these particular cases within the consumer-centric marketing paradigm will shed light on ways in which other organizations may be able to serve the poor profitably.

Finding Missing Markets (and a Disturbing Epilogue): Evidence from an Export Crop Adoption and Marketing Intervention in Kenya

Ashraf, Nava, Xavier Gine, Dean Karlan
March 2009

Farmers may grow crops for local consumption despite more profitable export options. DrumNet, a Kenyan NGO that helps small farmers adopt and market export crops, conducted a randomized trial to evaluate its impact. DrumNet services increased production of export crops and lowered marketing costs, leading to a 32% income gain for new adopters. The services collapsed one year later when the exporter stopped buying from DrumNet because farmers could not meet new EU production requirements. Farmers sold to other middlemen and defaulted on their loans from DrumNet. Such experiences may explain why farmers are less likely to adopt export crops.

Where Oil-Rich Nations Are Placing Their Global Bets

Abdelal, Rawi, Ayesha Khan, and Tarun Khanna

The combination of the gigantic American trade deficit and the price of oil at more than $130 per barrel (at press time) have created an inevitable pool of financial liquidity among oil exporters in the Arabian Gulf. But this era of petrodollar surpluses is markedly different from the last one. In the 1970s, the member states of the Gulf Cooperation Council-Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates-outsourced the management of their petrodollars to American and U.K. bankers. This time around, they have adopted active investment and development strategies: They are investing heavily in large Western organizations as well as in emerging markets in Africa and India. They are spending lavishly at home to establish institutional infrastructures, create free-trade zones for manufacturing and services, and build recreational facilities that will attract businesses, skilled knowledge workers, and tourists. All of this is destined to have long-run effects not just on their local economies but also on regional and international trading, argue the authors. In fact, the authors say, the actions of the GCC states are pulling the Gulf closer than it has ever been to the center of the international financial system. In this article, the authors consider how the economic landscape in the West will be affected by oil exporters' new investment strategies and interests over the next decades, how proximate emerging markets will be reshaped, and finally, how the GCC home environment itself will be dramatically reconfigured.

The Agglomeration of U.S. Ethnic Inventors

Kerr, William R.,
July 2008

The ethnic composition of U.S. inventors is undergoing a significant transformation-with deep impacts for the overall agglomeration of U.S. innovation. This study applies an ethnic-name database to individual U.S. patent records to explore these trends with greater detail. The contributions of Chinese and Indian scientists and engineers to U.S. technology formation increase dramatically in the 1990s. At the same time, these ethnic inventors became more spatially concentrated across U.S. cities. The combination of these two factors helps stop and reverse long-term declines in overall inventor agglomeration evident in the 1970s and 1980s. The heightened ethnic agglomeration is particularly evident in industry patents for high-tech sectors, and similar trends are not found in institutions constrained from agglomerating (e.g., universities, government).

Heart of Darkness: Business Tokens of the Congo (Part 1)

Wells, Louis T.
July 2008

Few numismatic fields are as unexplored as the tokens of what was once the Belgian Congo. Although the head (and "extra-wife") tokens have been thoroughly cataloged, I have found only one very early and incomplete attempt, by Mahieu in the 1920s, to report other tokens from this vast territory. Most of the tokens in this article that have not been previously listed were obtained in markets in Kinshasa between 2000 and 2005. Given the poor communications and regional violence, tokens from the eastern and even central part of the Congo were unlikely to appear in this western-located city. Probably many more tokens were issued in association with the Congo's important mines and plantations. This "Part I" article should serve as a start for the development of a "Part II" with a more complete list and history of issuing companies. Until then, the tokens of the former Belgian Congo and its independent successor states remain largely in darkness.

A Better Approach to Foreign Aid

Muzinich, Justin and Eric Werker
June 2008

Frustration with U.S. foreign aid is widespread. At the same time, flows of private development finance-including foreign direct investment and remittances-have begun to dwarf official aid. We suggest a new approach that harnesses the power of private development finance to direct it towards developmental and foreign policy goals. Specifically, we argue that tax credits for companies, and tax breaks for individuals, can be used to incentivize productive investments while being a positive force for meaningful reform in the developing world.

Learning Processes in Environmental Policy Making and Implementation

Ebrahim, Alnoor S.
February 2008

This paper explores how "learning" occurs in the context of environmental policy formulation and implementation. Rather than viewing policy learning as a rational and technocratic process, the emphasis here is on the political and institutional contexts within which opportunities for policy learning emerge. In particular, opportunities for policy learning are examined with respect to (a) agenda or priority-setting on environmental issues, (b) stakeholder access and representation in policy formulation, and (c) accountability in implementation. Examples are drawn from the experiences of South Africa and Brazil. Several preliminary factors are identified that may enhance policy learning, while acknowledging the constraints of bounded rationality and relationships of power.

Finding Missing Markets (and a disturbing epilogue): Evidence from an Export Crop Adoption and Marketing Intervention in Kenya (pdf)

Ashraf, Nava, Xavier Gine, and Dean Karlan
February 2008

In much of the developing world, many farmers grow crops for local or personal consumption despite export options which appear to be more profitable. Thus many conjecture that one or several markets are missing. We report here on a randomized controlled trial conducted by DrumNet in Kenya that attempts to help farmers adopt and market export crops. DrumNet provides smallholder farmers with information about how to switch to export crops, makes in-kind loans for the purchase of the agricultural inputs, and provides marketing services by facilitating the transaction with exporters. The experimental evaluation design randomly assigns pre-existing farmer self-help groups to one of three groups: (1) a treatment group that receives all DrumNet services, (2) a treatment group that receives all DrumNet services except credit, or (3) a control group. After one year, DrumNet services led to an increase in production of export-oriented crops and lower marketing costs; this translated into household income gains for new adopters. However, one year after the study ended, the exporter refused to continue buying the cash crops from the farmers because the conditions of the farms did not satisfy European export requirements. DrumNet collapsed in this region as farmers were forced to sell to middlemen and defaulted on their loans. The risk of such events may explain, at least partly, why many seemingly more profitable export crops are not adopted.

Leverage Time to Your Advantage

Malhotra, Deepak

June 2007

The article focuses on how to build agreements that last by leveraging some interesting insights offered by Ambassador Lakhdar Brahimi during his visit to Harvard Business School. As a United Nations special envoy to Afghanistan, Ambassador Brahimi was widely credited with helping to stabilize the nation in the aftermath of Taliban rule. Brahimi's perspective considers the role that time can play in maximizing value and strengthening relationships. Brahimi advises working constantly to establish and strengthen relationships and to learn as much as possible about contexts where one might some day need to negotiate.
