Impacts of an early education intervention on students' learning achievement: Evidence from the Philippines
No full textThis paper examines the impact of a large supply-side education intervention in the Philippines, the Third Elementary Education Project, on students' national achievement test scores. We find that the program significantly increased student test scores at grades 4 to 6. The estimate indicates that the six-year exposure to the program increases test scores by about 15 score points. Interestingly, the mathematics score is more responsive to this education reform than other subjects. We also find that textbooks, instructional training of teachers, and new classroom constructions particularly contributed to these outcomes. The empirical results also imply that early-stage investments improve student performance at later stages in the elementary school cycle, which suggests that social returns to such an investment are greater than what the current study demonstrates.School quality, policy intervention, elementary schools, human capital formation,
Overcoming successive bottlenecks: The evolution of a potato cluster in China
No full textAlthough the role of industrial policy in economic development is a frequent topic of debate in both the literature and the political arena, most such discussions focus on industrial policymaking at the national level. Using a case study of a potato cluster in China, we show that industrial policymaking at the local level contributes greatly to economic development. Many of the industrial policies affecting the cluster—including leveling land, developing better varieties, establishing a potato trade association, lobbying for increasing freight car quotas, and attracting processing firms—were implemented at the local level, highlighting the need for discussion of local industrial policymaking as a major determinant of cluster development. As the case study demonstrates, economic development is a continuous process with constantly evolving binding supply-side and demand-side constraints. Often, after a local policy helps remove one binding constraint, a new one emerges that, in turn, may require a new set of local policies. Therefore, the success of a potato cluster depends upon local industrial policies that respond to emerging binding constraints at different stages of the cluster's development.Economic transformation, clusters, comparative advantage, local industrial policy, Poverty,
A multiregion general equilibrium analysis of fiscal consolidation in South Africa:
No full textA multiregion applied general equilibrium model is used to examine the financial interactions among spheres of government in the context of fiscal consolidation. The framework combines nine regional submodels interacting through the trading of goods and services and the mobility of labor and capital. The model integrates intergovernmental fiscal transfers, which play an important role in reducing the disparity in living standards between regions. The analysis demonstrates that the current intergovernmental revenue transfer system has significant inter- and intraregional equity effects, although its nationwide impact is less important. Reducing intergovernmental transfers leads to a reduction in welfare in the four regions where the net transfers were initially positive (Limpopo, Eastern Cape, KwaZulu-Natal, and North West Province). In contrast, welfare increases in the five other regions (Northern Cape, Mpumalanga, Free State, Gauteng, and the Western Cape). When transfer revenues fall and, consequently, regional and local government revenues drop, poor households are the most affected, as they depend more on public services that are essentially financed by governments. When the government's fiscal position improves, it is also poor households that benefit more from additional government expenses.intergovernmental transfer, multiregion applied general equilibrium, consolidation, welfare,
Using the regression discontinuity design with implicit partitions: The impacts of comunidades solidarias rurales on schooling in El Salvador
No full textRegression discontinuity design (RDD) is a useful tool for evaluating programs when a single variable is used to determine program eligibility. RDD has also been used to evaluate programs when eligibility is based on multiple variables that have been aggregated into a single index using explicit, often arbitrary, weights. In this paper, we show that under specific conditions, regression discontinuity can be used in instances when more than one variable is used to determine eligibility, without assigning explicit weights to map those variables into a single measure.Regression discontinuity design, partitioned cluster analysis, Schooling, Impact evaluation,
Supply and demand for cereals in Nepal, 2010–2030:
No full textThis paper attempts to estimate the future supply and demand for cereals in Nepal. While there has been considerable research in the past examining the agricultural sector in Nepal, to the best of our knowledge there has been no analysis of the supply-demand scenario for food grains in the country. The analysis undertaken in this paper attempts to bridge this gap in the literature by estimating supply and demand models for the three most important cereals in Nepal's food basket: rice, wheat, and maize. The supply projections have been carried out on the basis of a single-crop production function model using data for the period 1995–2008. For estimating the demand function and projecting future demand, data from the Nepal Living Standards Survey II (NLSS II), undertaken in the year 2003/04, are used.cereal supply, cereal demand,
Can water allocation in the Yellow River basin be improved?: Insights from a multi-agent system model
No full textIn 1999, the Government of China enforced a cross-provincial, quota-based Water Allocation Agreement that was developed in 1987 and titled Unified Water Flow Regulation (UWFR) to ensure that flow to the Yellow River mouth would not be cut off. This policy was in line with the refocus of the Government, over the last decade, on sustainable water use and keeping the Yellow River healthy. The policy enforcement ended more than two decades of flow-cutoffs, that is, periods when the Yellow River did not reach the Bohai Sea at its mouth, during an increasing number of days every year.Water allocation, river basin management, multi-agent system,
Measuring the impacts of global trade reform with optimal aggregators of distortions:
No full textTraditional weighted-average measures of trade distortions are widely used in analyzing global and regional reforms, despite well-known deficiencies. This paper develops and applies optimal aggregators for the real-world case of multiple countries and commodities with much more detailed information on trade than on production and consumption. The approach reflects that different aggregators are needed for expenditure on imported goods and tariff revenues, and allows for incorporation of both intensive and extensive margins of adjustment to reform. Applications confirm that the technique is straightforward enough for widespread use, and point to close to a doubling of the welfare gains at the intensive margin when using the highest possible level of international commodity disaggregation, with larger gains in developing regions than in the industrial countries. The measured income gains increase along the entire path of liberalization, with slightly larger increases in the earlier stages, where the gaps between the responses of the expenditure and tariff revenue aggregators are largest. Sensitivity analysis suggests that, for global trade reform, the ease of substitution between tariff lines is much more important than that between varieties from different countries.aggregation, distortions, economic welfare measurement, Trade reform, trade restrictiveness,
How far do shocks move across borders?: Examining volatility transmission in major agricultural futures markets
No full textThis paper examines the level of interdependence and volatility transmission across major exchanges of maize, wheat, and soybeans in the United States, Europe, and Asia. We follow a multivariate GARCH approach to explore in detail and under different specifications the dynamics and cross-dynamics of volatility in agricultural futures markets. We account for the potential bias that may arise when considering exchanges with different closing times. The period of analysis is 2004–2009 for maize and soybeans and 2005–2009 for wheat. The results indicate that there is a strong correlation among international markets. In particular, we find both own- and cross-volatility spillovers and dependence between most of the exchanges. There is also higher interaction between the United States (Chicago) and both Europe and Asia than within the latter. The results further show the major role Chicago plays in terms of spillover effects over the other markets, particularly for maize and wheat. For soybeans, both China and Japan also exhibit important cross-volatility spillovers. Finally, the level of interdependence between exchanges has not necessarily increased in recent years for all commodities. From a policy perspective, these findings suggest that any potential regulatory scheme to address (excessive) price volatility in agricultural exchanges should be coordinated across markets; localized regulation will have limited effects given the high level of interrelation between markets.volatility transmission, agricultural commodities, futures markets, multivariate GARCH,
Evaluation of value-added agricultural advisory services: Case study of agriclinics in Southern India
No full textIntroduction of private enterprises to deliver agricultural advisory services is seen as a strategy to increase the coverage and effectiveness of the pluralistic extension system in developing countries. The Indian national program of agriclinics and agribusiness centers, started in 2002, aims to provide farmers with a reliable alternative to the private input dealer by subsidizing technically trained agricultural graduates to establish their own agricultural input shops and agriclinic laboratories. In 2008, Tamil Nadu state began its own version of the program, called Agriclinics cum Mini Soil Testing Laboratories, which provides subsidized funding to establish soil testing laboratories by primary agricultural cooperative banks (PACBs) or independent agricultural graduates.public–private partnership, Privatization, soil testing, agriclinic,
Women cotton farmers: Their perceptions and experiences with transgenic varieties: A case study for Colombia
No full textThis paper explores gender differences in cotton cultivation and looks into the perceptions and experiences of women and men with transgenic varieties. With few exceptions, researchers in the area of impact evaluation of crop biotechnology have only marginally included gender considerations in their work. This exploratory pilot study was developed in order to incorporate gender into our quantitative evaluation work. This study used a participatory and descriptive approach that allowed us to listen to women and men farmers' perceptions and insights. The project was conducted in the main cotton-producing regions of Colombia where a handful of transgenic varieties have been in the market for the past six years.crop biotechnology, Genetically modified crops, Genetic engineering, Cotton, Gender,
