Food Security, Poverty and Nutrition Policy Analysis
Food Security, Poverty and Nutrition Analysis provides essential insights into the evaluative techniques necessary for creating appropriate and effective policies and programs to address these worldwide issues. Food scientists and nutritionists will use this important information, presented in a conceptual framework and through case studies for exploring representative problems, identifying and implementing appropriate methods of measurement and analysis, understanding examples of policy applications, and gaining valuable insight into the multidisciplinary requirements of successful implementation.This book provides core information in a format that provides not only the concept behind the m...
Aggregate Effects of Imperfect Tax Enforcement
"This paper studies an economy in which the government is not able to perfectly enforce tax compliance among operating firms, and compares it with a similar economy but with perfect tax enforcement. I develop a competitive general equilibrium model where imperfect tax enforcement may affect aggregate outcomes through two mechanisms. First, it may distort firms' optimal output level as long as the probability of avoiding tax compliance is related to the firm's size. Second, poor tax enforcement may lead to a low provision of the public goods that complement firms' productivity. The results for a calibrated version of the model suggest that in economies with tax enforcement problems, aggregate output might be reduced by 12 percent. I also conclude that sizable aggregate effects can be obtained only when the public goods mechanism is at work."--Authors' abstract.
Agglomeration, Migration, and Regional Growth: A CGE Analysis for Uganda
"Uganda has experienced rapid economic growth and poverty reduction over the past decade but has failed to significantly improve incomes in its northern regions where prolonged conflict has hindered growth. We consider three strategies to close this regional divide: (1) develop a north-south corridor to encourage regional trade, (2) accelerate growth in the southern capital city and encourage north-south migration, and (3) improve agricultural productivity in rural areas. We examine these strategies using a regionalized computable general equilibrium model, accounting for internal migration and productivity gains from urban agglomeration effects. Simulation results indicate that a north-sout...
Impact of Soaring Food Price in Ethiopia: Does Location Matter?
"Previous studies implicitly assume uniform price-effects across regions or provinces within countries. They also do not address the issue of integration between the world food market and local markets. Instead, they assume a complete transmission of changes in world food prices to local food prices. In this paper, we first establish evidence of regional price heterogeneity across Ethiopia. We also applied the Johansen test for market integration over 95 local maize markets and found that none of the Ethiopian regional markets for maize is integrated to the world market. However, there is significant short-term price effects between the world maize market and some Ethiopian regional markets. Using the Almost Ideal Demand System, we estimate loss in household consumption and calorie intake as induced by food price increases. The results suggest a great deal of heterogeneity across regions as well as between rural and urban areas. Studies that fail to account for the characteristics of household demand across locations are more likely to induce misleading policy recommendations."--Authors' abstract.
Policy Reforms and Agriculture Development in Central Asia
Achieving sustainable agricultural development is at the forefront of the poverty reduction objective of the Central Asian republics - Kazakhstan, the Kyrgyz Republic, Tajikistan, Turkmenistan, and Uzbekistan. Since independence, the countries of the Central Asian region have undergone a series of transition from centrally planned economies to a more market oriented system. Wide-ranging policy reforms have been implemented, although in varying degrees, in the five Central Asian countries. Despite great efforts by the countries and the external advice and efforts of international agencies to help them to follow a dynamic growth path, the progress in policy reforms has been frustratingly slow....
Understanding Farmers' Perceptions and Adaptations to Climate Change and Variability: The Case of the Limpopo Basin, South Africa
Climate change is expected to have serious environmental, economic, and social impacts on South Africa. In particular, rural farmers, whose livelihoods depend on the use of natural resources, are likely to bear the brunt of adverse impacts. The extent to which these impacts are felt depends in large part on the extent of adaptation in response to climate change. This research uses a "bottom-up" approach, which seeks to gain insights from the farmers themselves based on a farm household survey. Farm-level data were collected from 794 households in the Limpopo River Basin of South Africa for the farming season 2004-2005. The study examines how farmer perceptions correspond with climate data re...
