This book explores recent experiences in the effort to bring about a Green Revolution in Sub-Saharan Africa (SSA). The chapters focus on rice and maize, which are promising and strategic smallholder crops. Significantly, we find that an African Rice Revolution has already begun in many irrigated areas, using Asian-type modern varieties, chemical fertilizer, and improved management practices. Further, we find that the same technological package significantly increases the productivity and profitability of rice farming in rainfed areas as well. We also find evidence that that management training, when done well, can boost productivity on smallholder farms. This suggests that African government...
One of the key questions in food policy debates in the last decades has been the role of cash cropping for achieving food security in low income countries. We revisit this question in the context of smallholder coffee production in Ethiopia. Using unique data collected by the authors on about 1,600 coffee farmers in the country, we find that coffee income improves food security, even after controlling for total income and other factors and after addressing the endogeneity of coffee income. Further analysis suggests that the pathway for achieving this improved food security is linked to being better able to smooth consumption across agricultural seasons. In contrast with food crops, coffee sales take place almost throughout the whole year, providing farmers with cash income also during the lean season.
Shows how colonial indirect rule and land tenure institutions create state weakness, ethnic inequality and insurgency in India, and around the world.
Populist rule is bad for democracy, yet in country after country, populists are being voted into office. Populism and Patronage shows that the populists such as Indira Gandhi and Narendra Modi win elections when the institutionalized ties between non-populist parties and voters decay. Yet, the explanations for this decay differ across different types of party system. Populism and Patronage focuses on the particular vulnerability of patronage-based party systems to populism. Patronage-based systems are ones in which parties depend on the distribution of patronage through a network of brokers to mobilize voters. Drawing on principal agent theory and social network theory, this book argues that...
The Economics of International Migration is a collection of the fundamental articles written by Giovanni Peri on the economic determinants and consequences of international migration. These papers have provided the theoretical framework and empirical analysis for a rethinking of the economics of migration, going beyond the Canonical model of labor demand and supply used until the 1990s. Beginning with a simple model that recognizes the differences between immigrants and natives as workers, the articles develop the analysis of complementarity, specialization and productivity effect of immigrants in developed economies. The book then presents a series of papers analyzing and testing the economic motivation for international migration. Finally, the focus is shifted to the effect of immigration policies and their consequences on immigration and the economy.
This volume presents advanced techniques to modeling markets, with a wide spectrum of topics, including advanced individual demand models, time series analysis, state space models, spatial models, structural models, mediation, models that specify competition and diffusion models. It is intended as a follow-on and companion to Modeling Markets (2015), in which the authors presented the basics of modeling markets along the classical steps of the model building process: specification, data collection, estimation, validation and implementation. This volume builds on the concepts presented in Modeling Markets with an emphasis on advanced methods that are used to specify, estimate and validate mar...

In addition to econometric essentials, this book covers important new extensions as well as how to get standard errors right. The authors explain why fancier econometric techniques are typically unnecessary and even dangerous.
The increasingly frequent and severe droughts prompted the global community to adopt more proactive and integrated approaches to reduce or neutralize the impacts. The paradigm shift called for an improved planning mechanism that puts emphasis on strengthening preparedness. In support of this process, the Drought Initiative, called by the Conference of Parties (COP) of the United Nations Convention to Combat Desertification (UNCCD), rolled out its programme on drought planning at national level. Showing the strong interest, 70 countries have already joined the programme to prepare their national drought plan. The development of a multi-criteria assessment for the review of the plans is a necessary step to enable the implementation. This publication contributes to this overall goal from multiple objectives, including the presentation of a replicable framework to conduct regular reviews, the analysis of the submitted plans to identify the potential for further enhancements, the provision of recommendations on the options of enhancements, and the demonstration of case studies with successful planning methods to facilitate the global knowledge-sharing.
