... This paper uses a field experiment to test whether intrahousehold heterogeneity in discount factors leads to inefficient strategic savings behavior. I gave married couples in rural Kenya the opportunity to open both joint and individual bank accounts at randomly assigned interest rates. I also directly elicited discount factors for all individuals in the experiment. Couples who are well matched on discount factors are less likely to use costly individual accounts and respond robustly to relative rates of return between accounts, while their poorly matched peers do not. Consequently, poorly matched couples forgo significantly more interest earnings on their savings.

... The “community-based development” approach may empower citizens and improve outcomes through three mechanisms: (1) an immediate direct effect of engaging citizens to decide how to allocate resources within the community-based development program, (2) an indirect effect on community organization that improves citizen engagement with other local institutions, and (3) an indirect effect on community organization that improves representation within centralized government structures. Using a randomized evaluation of a nongovernmental-organization-led CBD program in Ghana, we examine whether community-based development results in citizens’ empowerment to improve their socioeconomic well-being through these mechanisms. We find that the leadership training and experiences associated with community-based development translate into higher perceived quality of village leaders, but they simultaneously decrease contributions to collective projects outside the context of the community-based development program. In addition, although the process encourages more people to run for district-level office and results in more professional political representation, it does not increase aggregate levels of government investment in communities. Ultimately, we find that although the program led to changes in village-level and district-level leadership, it did not increase investment in public goods and did not improve socio-economic outcomes.

... This study contains CORONA satellite images that were used to identify sites and landscape features in northeastern Syria and adjacent regions. Most prominently, they are the source for the maps of sites and premodern trackways that appear in Ur, J. A. in press. Urbanism and Cultural Landscapes in Northeastern Syria: The Tell Hamoukar Survey, 1999-2001. Oriental Institute Publications 139. Chicago: University of Chicago Oriental Institute. All images are in Erdas Imagine (.img) format and are in the Universal Transverse Mercator (UTM) projection (Zone 37 north) using the WGS 1984 datum. For more information on the processing and interpretation of these CORONA scenes, see the above monograph.

Radiocarbon dates, sedimentology, and pollen counts from the late Holocene sediments of Oblong Tarn, Mount Kenya
Contributors: Courtney Mustaphi, Colin, Gajewski, Konrad, Marchant, Rob, Rosqvist, Gunhild
... Cores of the sediments from Oblong Tarn, Mount Kenya, were collected in 1983 and 1986, and were conventional radiocarbon dated to examine late Holocene glacier history of the mountain. Subsequently pollen samples were taken from both cores to create a composite pollen record.

... Shapefiles used in the optimization model presented in "High value of ecological information for river connectivity restoration" (Sethi et al.) In Review. Abstract: Efficient restoration of longitudinal river connectivity necessitates the use of sophisticated planning tools to maximize ecological benefits given constrained resources. Typically, ecological benefits of river barrier mitigation are measured using proxies such as the amount of accessible riverine habitat. We develop an optimization-based approach for targeting barrier mitigation which incorporates life history information of managed taxa. Findings are presented from an urbanizing salmon-bearing watershed in Alaska. Solutions informed by life history information outperformed those using only river connectivity proxies, demonstrating high value of ecological information in watershed restoration. For our study area, information on salmon ecology was typically valued at 0.8-1.2M USD based on costs savings for achieving a given benefit level relative to solutions derived with river connectivity proxies. This equated to 16-28% of the restoration budget. Investing in ecological studies may achieve win-win outcomes of improved understanding of aquatic ecology and greater watershed restoration efficiency.

... To see how the recent financial downturn affected workers nearing retirement, the Center for Retirement Research commissioned an Internet survey of 1,317 working Americans between the ages of 45 and 59. This survey was conducted by Knowledge Networks during July and August 2009 using their nationally representative panel. A subsample of 358 individuals who had at least $50,000 in pre-downturn retirement assets and experienced a loss of at least 10%, were asked to respond to four additional questions measuring the effect of financial literacy. The survey addressed a wide range of factors that could influence workers' response to the downturn, including socio-economic, financial, employment, and behavioral characteristics.

... To see if attitudes are changing about the potential for using one's home to cover living expenses in retirement, the Center for Retirement Research commissioned a survey that examined the house as a potential source of retirement income. Harris Interactive® conducted the study online within the United States between January 24 and February 2, 2007 among 2,673 adults (aged 50-65). Figures for age, sex, race, education, household income, and region were weighted where necessary to bring them into line with their actual proportions in the population. Propensity score weighting was also used to adjust for respondents’ propensity to be online. The questionnaire, results, and raw data from both surveys are available.

... This paper tests the effects on the take-up of a preventative health product of two interventions based on behavioral models derived from psychology: varying the framing of the perceived benefits; and having people verbally commit to purchase the product. I find that none of these interventions had a significant effect (whether economically or statistically) on take-up, and that the gender of the household member targeted was also irrelevant. In contrast, I find that take-up is sensitive to price, as in Cohen and Dupas (2008), and is correlated with indicators of household’s wealth.
Price Subsidies, Diagnostic Tests, and Targeting of Malaria Treatment: Evidence from a Randomized Controlled Trial
Contributors: Cohen, Jessica, Dupas, Pascaline, Schaner, Simone
... Both under- and over-treatment of communicable diseases are public bads. But efforts to decrease one run the risk of increasing the other. Using rich experimental data on household treatment-seeking behavior in Kenya, we study the implications of this tradeoff for subsidizing life-saving antimalarials sold over-the-counter at retail drug outlets. We show that a very high subsidy (such as the one under consideration by the international community) dramatically increases access, but nearly half of subsidized pills go to patients without malaria. We study two ways to better target subsidized drugs: reducing the subsidy level and introducing rapid malaria tests over-the-counter.
