This book presents the basic model of an agricultural household that underlies most of the case studies undertaken so far. The model assumes that households are price-takers and is therefore recursive. The decisions modeled include those affecting production and the demand for inputs and those affecting consumption and the supply of labor. Comparative results on selected elasticities are presented for a number of economies. The empirical significance of the approach is demonstrated in a comparison of models that treat production and consumption decisions separately and those in which the decisionmaking process is recursive. The book summarizes the implications of agricultural pricing policy for the welfare of farm households, marketed surplus, the demand for nonagricultural goods and services, the rural labor market, budget revenues, and foreign exchange earnings. In addition, it is shown that the basic model can be extended in order to explore the effects of government policy on crop composition, nutritional status, health, saving, and investment and to provide a more comprehensive analysis of the effects on budget revenues and foreign exchange earnings. Methodological topics, primarily the data requirements of the basic model and its extensions, along with aggregation, market interaction, uncertainty, and market imperfections are discussed. The most important methodological issues - the question of the recursive property of these models - is also discussed.
A model addressing agricultural responses to public interventions is described. The model is confined to the short run, and it allows an assessment of the policy significance of changes in five variables that are exogenous to the household. The first variable is the price of the main agricultural output, emphasizing the elasticities of both output and market surplus; the second is the wage rate for agricultural labor, focusing on the elasticities of household labor supply and demand for hired labor; the third is the size of the family labor force, which is essential for estimating shadow wage rates; the fourth is the number of dependents, in order to permit an assessment of family planning policies; and the final variable is technology. The main features of the model are the role of the labor market, household production, household consumption, and the aggregate effect of household responses. Applicaton of the model to the Muda River Valley demonstrates that it is appropriate to a number of policy isues ranging from output price intervention to technological innovaton. Specifically, the model indicates that the economic cost of rural to urban migration is small when compared to the marginal productivity of the migrant before his departure.
The Farm Labor Problem: A Global Perspective explores the unique character of agricultural labor markets and the implications for food production, farm worker welfare and advocacy, and immigration policy. Agricultural labor markets differ from other labor markets in fundamental ways related to seasonality and uncertainty, and they evolve differently than other labor markets as economies develop. We weave economic analysis with the history of agricultural labor markets using data and real-world events. The farm labor history of California and the United States is particularly rich, so it plays a central role in the book, but the book has a global perspective ensuring its relevance to Europe and high-income Asian countries. The chapters in this book provide readers with the basics for understanding how farm labor markets work (labor in agricultural household models, farm labor supply and demand, spatial market equilibria); farm labor and immigration policy; farm labor organizing; farm employment and rural poverty; unionization and the United Farm Workers movement; the Fair Food Program as a new approach to collective bargaining; the declining immigrant farm labor supply; and what economic development in relatively low-income countries portends for the future of agriculture in the United States and other high-income countries. The book concludes with a chapter called "Robots in the Fields," which extrapolates current trends to a perhaps not-so-distant future. The Farm Labor Problem serves as both a guide to policy makers, farmworker advocates and international development organizations and as a textbook for students of agricultural economics and economics. - Describes the unique character of agricultural labor markets providing consequential insights - Contextualizes the economics of agricultural labor with a global perspective - Examines the history of farm labor, immigration, policy and collective bargaining with a view to the future
Agricultural mechanization in Africa south of the Sahara — especially for small farms and businesses — requires a new paradigm to meet the needs of the continent’s evolving farming systems. Can Asia, with its recent success in adopting mechanization, offer a model for Africa? An Evolving Paradigm of Agricultural Mechanization Development analyzes the experiences of eight Asian and five African countries. The authors explore crucial government roles in boosting and supporting mechanization, from import policies to promotion policies to public good policies. Potential approaches presented to facilitating mechanization in Africa include prioritizing market-led hiring services, eliminating distortions, and developing appropriate technologies for the African context. The role of agricultural mechanization within overall agricultural and rural transformation strategies in Africa is also discussed. The book’s recommendations and insights should be useful to national policymakers and the development community, who can adapt this knowledge to local contexts and use it as a foundation for further research.
This volume is written primarily for agricultural economists doing research on productivity. It includes discussions of the theoretical underpinnings of productivity measurement as well as the many practical considerations that go into translating this theory into actual measures of aggregated outputs and inputs. The unifying concept of agricultural productivity used across the chapters of this volume is aggregate total factor productivity (TFP) of the sector. The volume also contains detailed analysis of the underlying causes of agricultural productivity growth. Part I (chapters 2-6) examines agricultural productivity in high-income and transition countries. Part II (chapters 7-11) examines agricultural productivity growth and its driving forces in five important agricultural producers in Asia and Latin America. Part III (chapters 12-14) focuses on measuring and identifying constraints to agricultural productivity growth in sub-Saharan Africa. Part IV (chapters 15-16) gives a global perspective on agricultural productivity.
Significant recent changes in the structure and composition of households make the study of the economic relationships within the household of particular interest for academics and policy-makers. In this context, Household Economic Behaviors, through its focus on theoretical and empirical chapters on a range of economic behaviors within the household, provides a new and timely viewpoint. Following the Introduction and one or two surveys which give a general background, the volume includes theoretical and empirical perspectives on allocation of available time within the household, monetary and non-monetary transfers between household members, and intra-household bargaining.

To understand the impacts of support programs on global emissions, this paper considers the impacts of domestic subsidies, price distortions at the border, and investments in emission-reducing technologies on global greenhouse gas (GHG) emissions from agriculture. In a step towards a full evaluation of the impacts, it uses a counterfactual global model scenario showing how much emissions from agricultural production would change if agricultural support were abolished worldwide. The analysis indicates that, without subsidies paid directly to farmers, output of some emission-intensive activities and agricultural emissions would be smaller. Without agricultural trade protection, however, emissions would be higher. This is partly because protection reduces global demand more than it increases global agricultural supply, and partly because some countries that currently tax agriculture have high emission intensities. Policies that directly reduce emission intensities yield much larger reductions in emissions than those that reduce emission intensities by increasing overall productivity because overall productivity growth creates a rebound effect by reducing product prices and expanding output. A key challenge is designing policy reforms that effectively reduce emissions without jeopardizing other key goals such as improving nutrition and reducing poverty. While the scenario analysis in this paper does not propose any particular policy reform, it does provide an important building block towards a full understanding the impacts of repurposed agricultural support measures on mitigation of greenhouse gas emissions and adaptation to climate change. That full analysis is being undertaken in subsequent work, which will also take account of land-use change and alternative forms of agricultural policy support to align objectives of food security, farmers’ income security, production efficiency and resilience, and environmental protection.
This collection of essays honors a remarkable man and his work. Erik Thorbecke has made significant contributions to the microeconomic and the macroeconomic analysis of poverty, inequality and development, ranging from theory to empirics and policy. The essays in this volume display the same range. As a collection they make the fundamental point that deep understanding of these phenomena requires both the micro and the macro perspectives together, utilizing the strengths of each but also the special insights that come when the two are linked together. After an overview section which contains the introductory chapter and a chapter examining the historical roots of Erik Thorbecke's motivations, the essays in this volume are grouped into four parts, each part identifying a major strand of Erik's work—Measurement of Poverty and Inequality, Micro Behavior and Market Failure, SAMs and CGEs, and Institutions and Development. The range of topics covered in the essays, written by leading authorities in their own areas, highlight the extraordinary depth and breadth of Erik Thorbecke's influence in research and policy on poverty, inequality and development. Acknowledgements These papers were presented at a conference in honor of Erik Thorbecke held at Cornell University on October 10-11, 2003. The conference was supported by the funds of the H. E. Babcock Chair in Food, Nutrition and Public Policy, and the T. H. Lee Chair in World Affairs at Cornell University.
