Rapid population growth in many developing countries has raised concerns regarding food security and household welfare. To understand the consequences of population growth on in the general equilibrium setting, we examine the dynamics of population density and its impacts on household outcomes using panel data from Indonesia. More specifically we explicitly highlight the importance of migration to urban sectors in the analysis. Empirical results show that human capital in the household determines the effect of increased population density on per capita household consumption expenditure. The effect of population density is positive if the average educational attainment is high (above junior high school), while it is negative otherwise. On the other hand, farmers with larger holdings maintain their advantage in farming regardless of population density. The paper concludes with some potential lessons for African countries from Indonesias more successful rural development experiences.
Rising densities of human settlements, migration and transport to reduce distances to market, and specialization and trade facilitated by fewer international divisions are central to economic development. The transformations along these three dimensions density, distance, and division are most noticeable in North America, Western Europe, and Japan, but countries in Asia and Eastern Europe are changing in ways similar in scope and speed. 'World Development Report 2009: Reshaping Economic Geography' concludes that these spatial transformations are essential, and should be encouraged. The conclusion is not without controversy. Slum-dwellers now number a billion, but the rush to cities continues. Globalization is believed to benefit many, but not the billion people living in lagging areas of developing nations. High poverty and mortality persist among the world's 'bottom billion', while others grow wealthier and live longer lives. Concern for these three billion often comes with the prescription that growth must be made spatially balanced. The WDR has a different message: economic growth is seldom balanced, and efforts to spread it out prematurely will jeopardize progress. The Report: documents how production becomes more concentrated spatially as economies grow. proposes economic integration as the principle for promoting successful spatial transformations. revisits the debates on urbanization, territorial development, and regional integration and shows how today's developers can reshape economic geography.
Throughout the world, migration is an increasingly important and diverse component of population change, both at national and sub-national levels. Migration impacts on the distribution of knowledge and generates externalities and spillover effects. This book focuses on recent models and methods for analysing and forecasting migration, as well as on the basic trends, driving factors and institutional settings behind migration processes. Migration and Human Capital also looks at many current policy issues regarding migration, such as the creative class in metropolitan areas, the brain drain, regional diversity, population ageing, illegal immigration, ethnic networks and immigrant assimilation. With specific reference to Europe and North America, the book reviews and applies models of internal migration; analyses the spatial concentration of human capital; considers migration in a family context; and addresses the political economy of international migration. This book will be invaluable for researchers and policy makers in the fields of internal and international migration. It provides up-to-date readings for advanced courses that focus on migration and population change in a global context.
This study has been conducted in order to generate evidence of the visibility of exit from farm input subsidies in an African context. The study simulates the impact of alternative exit strategies from Malawis farm input subsidy program on maize markets. The simulation is conducted using a multiequation partial equilibrium model of the national maize market, which is sequentially linked via a price-linkage equation to local rural maize markets. The model accounts for market imperfections prevailing in the country that arise from government price interventions. Findings show that some alternative exit strategies have negative and sustained impacts on maize yields, production, and acreage allocated to maize over the simulation period. Market prices rise steadily as a result of the implementation of different exit strategies. Despite higher maize prices, domestic maize consumption remains fairly stable, with a slow but increasing trend over the simulation period. Results further suggest that exit strategies that are coupled with improvements in agricultural extension services have the potential to offset the negative impacts of the removal or scaling down of agricultural input subsidies. The study findings demonstrate the difficulty of feasibly removing farm input subsidies. Study recommendations are therefore relevant for policymakers and development partners debating removal or implementation of farm input subsidies.
Indias National Rural Employment Guarantee Scheme (NREGS) is one of the largest public works programs globally. Understanding the impacts of NREGS and the pathway through which its impacts are realized thus has important policy implications. We use a three-round 4,000-household panel from Andhra Pradesh together with administrative data to explore short- and medium-term poverty and welfare effects of NREGS. Triple difference estimates suggest that participants significantly increase consumption (protein and energy intake) in the short run and accumulate more nonfinancial assets in the medium term. Direct benefits exceed program-related transfers and are most pronounced for scheduled castes and tribes and households supplying casual labor. Asset creation via program-induced land improvements is consistent with a medium-term increase in assets by nonparticipants and increases in wage income in excess of program cost.
Human capital—the knowledge, skills, and health that people accumulate over their lives—is a central driver of sustainable growth, poverty reduction, and successful societies. More human capital is associated with higher earnings for people, higher income for countries, and stronger cohesion in societies. Much of the hard-won human capital gains in many economies over the past decade is at risk of being eroded by the COVID-19 (coronavirus) pandemic. Urgent action is needed to protect these advances, particularly among the poor and vulnerable. Designing the needed interventions, targeting them to achieve the highest effectiveness, and navigating difficult trade-offs make investing in better measurement of human capital now more important than ever. The Human Capital Index (HCI)—launched in 2018 as part of the Human Capital Project—is an international metric that benchmarks the key components of human capital across economies. The HCI is a global effort to accelerate progress toward a world where all children can achieve their full potential. Measuring the human capital that children born today can expect to attain by their 18th birthdays, the HCI highlights how current health and education outcomes shape the productivity of the next generation of workers and underscores the importance of government and societal investments in human capital. The Human Capital Index 2020 Update: Human Capital in the Time of COVID-19 presents the first update of the HCI, using health and education data available as of March 2020. It documents new evidence on trends, examples of successes, and analytical work on the utilization of human capital. The new data—collected before the global onset of COVID-19—can act as a baseline to track its effects on health and education outcomes. The report highlights how better measurement is essential for policy makers to design effective interventions and target support. In the immediate term, investments in better measurement and data use will guide pandemic containment strategies and support for those who are most affected. In the medium term, better curation and use of administrative, survey, and identification data can guide policy choices in an environment of limited fiscal space and competing priorities. In the longer term, the hope is that economies will be able to do more than simply recover lost ground. Ambitious, evidence-driven policy measures in health, education, and social protection can pave the way for today’s children to surpass the human capital achievements and quality of life of the generations that preceded them.
This valuable book summarizes recent research by experts from both the natural and social sciences on the effects of population growth on land use. It is a useful introduction to a field in which little quantitative research has been conducted and in which there is a great deal of public controversy. The book includes case studies of African, Asian, and Latin American countries that demonstrate the varied effects of population growth on land use. Several general chapters address the following timely questions: What is meant by land use change? Why are ecological research and population studies so different? What are the implications for sustainable growth in agricultural production? Although much work remains to be done in quantifying the causal connections between demographic and land use changes, this book provides important insights into those connections, and it should stimulate more work in this area.
Population, Land Use, and Environment: Research Directions offers recommendations for future research to improve understanding of how changes in human populations affect the natural environment by means of changes in land use, such as deforestation, urban development, and development of coastal zones. It also features a set of state-of-the-art papers by leading researchers that analyze population-land useenvironment relationships in urban and rural settings in developed and underdeveloped countries and that show how remote sensing and other observational methods are being applied to these issues. This book will serve as a resource for researchers, research funders, and students.
This paper analyses the impact of large and persistent emigration from Eastern European countries over the past 25 years on these countries’ growth and income convergence to advanced Europe. While emigration has likely benefited migrants themselves, the receiving countries and the EU as a whole, its impact on sending countries’ economies has been largely negative. The analysis suggests that labor outflows, particularly of skilled workers, lowered productivity growth, pushed up wages, and slowed growth and income convergence. At the same time, while remittance inflows supported financial deepening, consumption and investment in some countries, they also reduced incentives to work and led to exchange rate appreciations, eroding competiveness. The departure of the young also added to the fiscal pressures of already aging populations in Eastern Europe. The paper concludes with policy recommendations for sending countries to mitigate the negative impact of emigration on their economies, and the EU-wide initiatives that could support these efforts.
As the world's population exceeds an incredible 6 billion people, governmentsâ€"and scientistsâ€"everywhere are concerned about the prospects for sustainable development. The science academies of the three most populous countries have joined forces in an unprecedented effort to understand the linkage between population growth and land-use change, and its implications for the future. By examining six sites ranging from agricultural to intensely urban to areas in transition, the multinational study panel asks how population growth and consumption directly cause land-use change, and explore the general nature of the forces driving the transformations. Growing Populations, Changing Landscapes explains how disparate government policies with unintended consequences and globalization effects that link local land-use changes to consumption patterns and labor policies in distant countries can be far more influential than simple numerical population increases. Recognizing the importance of these linkages can be a significant step toward more effective environmental management.
