Relation of waste generation and composition to socio-economic factors: a case study.

Abstract: To develop an effective waste management strategy for a given region, it is important to know the amount of waste generated and the composition of the waste stream. Past research has shown that the amount of waste generated is proportional to the population and the average mean living standards or the average income of the people. In addition, other factors may affect the amount and composition of waste. These are climate, living habits, level of education, religious and cultural beliefs, and social and public attitudes. This paper presents the findings of a study carried out in a suburban municipal area in Sri Lanka to determine the solid waste generation rate and waste composition based on field surveys and to determine the related socio-economic factors. A database was developed that included information on the quantity and composition of waste generated in a sample of households in the study area over a time period. The collected data was analysed to relate waste generation and composition data to various socio-economic factors. Over 400 sample households were selected for the study using a stratified random sampling methodology based on municipal wards and property values. A technique that considers both the number of households in a particular income group (property value range) and the standard deviation of property values within a given income group was used to determine the appropriate sample size for each municipal ward. Through category and regression analyses, the quantities of waste and waste composition were related to several socio-economic factors. The paper describes the basis for the sample selection, the methodology adopted for data collection, the socio-economic parameters used for the analysis, and the relationships developed from the analysis.

Strengthening agricultural extension and advisory systems : procedures for assessing, transforming, and evaluating extension systems

Abstract: The purpose of this paper is to provide information on how to transform and strengthen pluralistic agricultural extension and advisory systems in moving toward the broader goal of increasing farm income and improving rural livelihoods. The focus of this book is primarily on the technical knowledge, management skills, and information services that small-scale farm households will need to improve their livelihoods in the rapidly changing global economy. In addition, the book will also include information on how extension should help all types of farmers in dealing with escalating natural resource problems, including climate change. The primary focus of this paper will be a comparative analysis of different extension strategies, organizational models, institutional innovations, and resource constraints and how an extension system might be transformed and strengthened through specific policy and organizational changes as well as needed investments. This paper is organized into nine chapters. These chapters follow an institution building strategy used by many donors and governments as they seek to improve their extension system. The diagram in Figure one outlines these basic planning, implementation, and evaluation procedures that will be considered. The sections outlined below will provide a brief overview of the different chapters included in this paper.

Multi-product exporters: product churning, uncertainty and export discoveries*

Abstract: Recent research on international trade focuses on firm-product-level heterogeneity and the role of uncertainty in shaping international trade. This article contributes to the literature by examining product-level dynamics within firms in the context of Mexican trade integration under NAFTA. The data show intense product churning within firms and confirm the existence of within-firm product heterogeneity. The data indicate that new exporters enter foreign markets with a small number of varieties, most of which were previously sold at home, and with a small export small volume. The data also suggest that export discoveries are relatively rare and are imitated within a short period of time. To deepen the understanding of the complex interactions between globalisation and economic development, trade economists have recently increased their interest in two related areas: the link between micro-heterogeneity and aggregate export response, and the role of uncertainty in international trade. It has been recognised that progress in both areas can contribute to devising more effective policies for promoting growth (Hausmann and Rodrik, 2003; Bartelsman and Doms, 2000; Tybout, 2000).

When is external debt sustainable

Abstract: The article empirically examines the determinants of debt distress, defined as periods in which countries resort to any of three forms of exceptional finance: significant arrears on external debt, Paris Club rescheduling, and non-concessional International Monetary Fund lending. Probit regressions show that three factors explain a substantial fraction of the cross-country and time-series variation in the incidence of debt distress: the debt burden, the quality of policies and institutions, and shocks. The relative importance of these factors varies with the level of development. These results are robust to a variety of alternative specifications, and the core specifications have substantial out-of-sample predictive power. The quantitative implications of these results are examined for the lending strategies of official creditors.
