Book Description
Much policy interest in sanitation and hygiene promotion focuses on changing behavior and increasing demand for these goods. Yet the effectiveness of large-scale interventions has been mixed, in large part because of the difficulty of changing attitudes on deeply rooted behaviors. This study tests whether an experiential learning exercise structured around an experimental game can be used to shift preferences around sanitation and hygiene. A minimum coordination game is adapted to the sanitation and hygiene setting by linking game choices to real-world investment decisions and payoffs in terms of health and status. Individuals from 20 villages in rural Tamil Nadu were randomly assigned to one of three groups: one that played a game in which communication between rounds was allowed, another that played a game in which communication was prohibited, and a control group that only completed a survey. Based on a comparison of survey responses across treatment arms, the game improved stated preferences in relation to sanitation and hygiene. This effect was larger when communication was allowed, and men responded on average more strongly than women across both versions of the game. These results suggest that experimental games can be a valuable tool not only for the study of decision making but for improving participants’ knowledge and pro-sanitation preferences.

Book Description
This study focuses on the feed milling industry, which serves as the link between maize and poultry, through a field assessment of feed millers in Ghana. The findings establish the importance of feed in the poultry value chain. In addition, they show how the sector has become more integrated with poultry production, especially on larger-scale poultry farms. Because maize accounts for 60 percent of poultry feed, its availability and price have important implications for the profitability and growth potential of feed and, therefore, for poultry production as well. We illustrate these linkages by means of a simple spatial market equilibrium model that ties together the three sectors of the poultry value chain: the primary inputs (maize and soybeans), intermediate inputs (feed), and final products (meat and eggs). This model also enables us to assess the future growth potential of the poultry industry given alternative policy-driven changes in productivity and the production capacities of all three sectors. The results show that for poultry meat, replacing imports with domestic production in the short term would be nearly impossible. For the egg industry, however, there is potential for Ghana to export to neighboring countries by reducing production costs through improvements in yellow maize production.

Book Description
Urbanization has had a major impact on livelihoods in Ghana and throughout Africa as a whole. However, much research on urbanization has focused on effects occurring within cities, while there is insufficient understanding of its effects on rural areas. This paper examines the impact of urbanization—through a typology of districts—on rural livelihoods in Ghana. The country’s districts are classified into seven spatial groups according to the size of the largest city in each district in southern and northern Ghana. The paper does not address rural–urban migration but instead focuses on the livelihoods of rural households. In contrast to the extensive literature focusing on the effects of urbanization on individuals, we assess its impacts on individual rural households as a whole, with a particular focus on youth-headed households. Many rural households have shifted their primary employment from agriculture to nonagriculture, especially in the more urbanized South. In contrast, change in livelihood diversification within rural households with family members’ primary employment in both agriculture and nonagriculture appears much less rapid. Rural youth-headed households are significantly more associated with the transition away from agriculture than households headed by other adults, and such trends are stronger in locations closer to larger cities, particularly in the South. Although the nonagricultural economy is becoming increasingly important for rural households, contrary to expectations, the probit model analysis in this paper shows that agricultural production does not appear to be more intensified—in terms of modern input use—in the more urbanized South, and youth do not show greater agricultural technology adoption than other adults, indicating that the constraints against modern input adoption may be binding for all farmers, including youth and farmers in more urbanized locations. We also find that rural poverty rates are consistently lower among nonagricultural households, and the share of middle-class population is also disproportionally higher among rural nonagricultural households than agricultural households. While the probit analysis confirms the positive relationship between being a nonagricultural household and being nonpoor or becoming middle class after controlling for all other factors, education seems to play the biggest role. As rural youth become more educated and more households shift from agriculture to the rural nonfarm economy, a different range of technologies for agricultural intensification is necessary for agriculture to be attractive for youth. A territorial approach and related policies that integrate secondary cities and small towns with the rural economy deserve more attention such that the diversification of rural livelihoods can become a viable alternative or complement to rural–urban migration for youth.

Book Description
Understanding how various entities in a policy system at the national level can contribute to improved use of evidence in policy making. Yet little research has focused in developing countries on how various actors and players in a policy system work together to achieve a set of policy goals. In this paper, we study the factors contributing to the effectiveness of a policy system. The process of policy design, adoption, implementation, and refinement requires an effective policy system as well as a capacitated and supportive institutional structure. External actors both through technical and financial assistance often support policy systems in developing countries. Poor coordination and harmonization of such assistance among various actors and players within the country can often result in undermining the very policy systems they try to strengthen. This is typical in the African agricultural development process. In this paper, we develop a conceptual framework for understanding the policy and institutional architecture of food and agriculture policy system and for improving the coordination and harmonization of the roles of policy actors and players. Applying the framework to Ghana, we map and analyze the organizational contributions of various actors and their functional characteristics. We show how such analysis can aid various policy actors in setting priorities and strategies for increasing their capacity and the effectiveness of their roles. Finally, we draw lessons for strengthening the food policy systems in developing countries through effective coordination among local and external actors.

Book Description
This paper develops a novel methodology to estimate the degree of spatial basis risk for an arbitrary rainfall index insurance instrument. It relies on a widelyused stochastic rainfall generator, extendedto accommodate nontraditional dependence patterns—in particular spatial upper-tail dependence in rainfall—through a copula function. The methodology is applied to a recentlylaunched index product insuring against excess rainfall in Uruguay. The model is first calibrated using historical daily rainfall data from the national network of weather stations, complemented with a unique,high-resolution dataset from a dense network of 34 automatic weather stations around the study area. The degree of downside spatial basis risk is then estimated by Monte Carlo simulations and the results are linked to both a theoretical model of the demand for index insurance and to farmers’ perceptions about the product.

Book Description
This paper assesses the Subramanian and Deaton (S–D) approach for imputing the caloric intake of households from food prepared away from home (FAFH) and composite foods (CF) by juxtaposing it with the imputations of alternative approaches, and extends these approaches to four additional nutrients—vitamin A, iron, zinc, and calcium. The apparent relative nutritional insignificance of FAFH and CF in Bangladesh obfuscates our efforts to assess alternatives to the S–D approach to imputation, and we remain uncertain about the relative value of the alternative imputation approaches examined. FAFH and CF—although widely consumed in Bangladesh—constitute a relatively unimportant source of nutrients, regardless of how the nutrient content of FAFH and CF is imputed.

Book Description
The aim of this Handbook is twofold: to educate and to inspire. It is meant for researchers and graduate students who are interested in taking a data-based and behavioral approach to the study of game theory. Educators and students of economics will find the Handbook useful as a companion book to conventional upper-level game theory textbooks, enabling them to compare and contrast actual behavior with theoretical predictions. Researchers and non-specialists will find valuable examples of laboratory and field experiments that test game theoretic propositions and suggest new ways of modeling strategic behavior. Chapters are organized into several sections; each section concludes with an inspirational chapter, offering suggestions on new directions and cutting-edge topics of research in experimental game theory.

Book Description
Throughout the history of economic ideas, it has often been asserted that experimentation is impossible, yet, in fact, history shows that the idea of ‘experimentation’ has always been important, and as such has been interpreted and put to use in many ways. Rich in historical detail, the essays in this topical volume deal with such issues as laboratory experimentation, the observed transition from a post-war economics to a contemporary discipline, the contrasting positions of Friedrich Hayek and Oskar Morgenstern, the socio-economic experiments proposed by Ernest Solvay and Knut Wicksell, and a rigorous examination of the way in which economic models can or cannot be construed as valid experiments producing useful knowledge. A testament to the variety of ways in which experimentation has been of importance in the creation of economic knowledge, these wide-ranging essays will interest those seeking to expand their historical understanding of the discipline, be they theorists, historians, philosophers, advanced students or researchers.

Book Description
An indispensable survey of new developments and results in experimental economics When The Handbook of Experimental Economics first came out in 1995, the notion of economists conducting lab experiments to generate data was relatively new. Since then, the field has exploded. This second volume of the Handbook covers some of the most exciting new growth areas in experimental economics, presents the latest results and experimental methods, and identifies promising new directions for future research. Featuring contributions by leading practitioners, the Handbook describes experiments in macroeconomics, charitable giving, neuroeconomics, other-regarding preferences, market design, political economy, subject population effects, gender effects, auctions, and learning and the economics of small decisions. Contributors focus on key developments and report on experiments, highlighting the dialogue between experimenters and theorists. While most of the experiments consist of laboratory studies, the book also includes several chapters that report extensively on field experiments related to the subject area studied.
