Social Security in Developing Countries

Abstract: The term `social security' has a very different meaning in underdeveloped countries and is best understood as poverty alleviation. This book attempts to define social security in the Third World and to examine what sort of programmes are most suitable for developing countries. The authors review current literature on the subject. Some chapters explore broad themes, others describe social security provisions in various regions in India, China, Latin America, and Southern Africa. Western systems are compared and broad assessments made of the traditional social security systems in Third World village societies. The editors aim to put the subject of social security firmly on the agenda of development economic research with a view to stimulate much further research in this area. The book is written in a way that will be accessible to a much wider audience.

Values and choice

Abstract: This chapter discusses the welfare economics and value judgments. Welfare economics is concerned with policy recommendations. It explores the ways of arriving at such conclusions as given the choice between social states x and y, x should be chosen. It is obvious that welfare economics cannot be value-free, for the recommendations it aims to arrive at are themselves value judgments. In view of this it must be regarded as somewhat of a mystery that so many notable economists have been involved in debating the prospects of finding value-free welfare economics. The New Welfare Economics was much concerned with deriving policy judgments from purely factual premises. The Pareto principle has been often taken to be free from value judgments. On the negative side, Robbins celebrated attack on the use of value judgments in economics concentrated exclusively on the difficulties of interpersonal comparison. The Hicksian comment on the objectivity of the compensation test is also based on the idea that if compensations are paid, everyone is better off, and there is no interpersonal conflict.

Volume 1: Entitlement and Well-being

Abstract: WIDER Studies in Development Economics The World Institute for Development Economics Research, established in 1984, started work in Helsinki in 1985, with the financial support of the Government of Finland. The principal purpose of the Institute is to help identify and meet the need for policy-oriented socio-economic research on pressing global and development problems and their inter-relationships. WIDER's research projects are grouped into three main themes: hunger and poverty; money, finance, and trade; and development and technological transformation. BL Sen is an internationally renowned, prizewinning economist This volume is the first of three addressing a wide range of policy issues relating to the role of public action in combating hunger and deprivation in the modern world. It deals with the background nutritional, economic, social, and political aspects of the problem of world hunger. Topics covered include the characteristics and causal antecedents of famines and endemic deprivation, the interconnections between economic and political factors, the role of social relations and the family, the special problems of women's deprivation, the connection between food consumption and other indicators of living standards, and the medical aspects of undernourishment and its consequences. Several contributions also address the political background of public policy, in particular the connection between the government and the public, including the role of newspapers and the media, and the part played by political commitment and by adversarial politics and pressures. Taken together, these essays provide a comprehensive and authoritative analysis of the problem of hunger and deprivation, and an important guide for action.

On Happiness and Human Potentials: A Review of Research on Hedonic and Eudaimonic Well-Being

Abstract: ▪ Abstract Well-being is a complex construct that concerns optimal experience and functioning. Current research on well-being has been derived from two general perspectives: the hedonic approach, which focuses on happiness and defines well-being in terms of pleasure attainment and pain avoidance; and the eudaimonic approach, which focuses on meaning and self-realization and defines well-being in terms of the degree to which a person is fully functioning. These two views have given rise to different research foci and a body of knowledge that is in some areas divergent and in others complementary. New methodological developments concerning multilevel modeling and construct comparisons are also allowing researchers to formulate new questions for the field. This review considers research from both perspectives concerning the nature of well-being, its antecedents, and its stability across time and culture.

Agricultural sustainability and intensive production practices

Abstract: A doubling in global food demand projected for the next 50 years poses huge challenges for the sustainability both of food production and of terrestrial and aquatic ecosystems and the services they provide to society. Agriculturalists are the principal managers of global useable lands and will shape, perhaps irreversibly, the surface of the Earth in the coming decades. New incentives and policies for ensuring the sustainability of agriculture and ecosystem services will be crucial if we are to meet the demands of improving yields without compromising environmental integrity or public health.

Dynamics of dark energy

Abstract: We review in detail a number of approaches that have been adopted to try and explain the remarkable observation of our accelerating universe. In particular we discuss the arguments for and recent progress made towards understanding the nature of dark energy. We review the observational evidence for the current accelerated expansion of the universe and present a number of dark energy models in addition to the conventional cosmological constant, paying particular attention to scalar field models such as quintessence, K-essence, tachyon, phantom and dilatonic models. The importance of cosmological scaling solutions is emphasized when studying the dynamical system of scalar fields including coupled dark energy. We study the evolution of cosmological perturbations allowing us to confront them with the observation of the Cosmic Microwave Background and Large Scale Structure and demonstrate how it is possible in principle to reconstruct the equation of state of dark energy by also using Supernovae Ia observational data. We also discuss in detail the nature of tracking solutions in cosmology, particle physics and braneworld models of dark energy, the nature of possible future singularities, the effect of higher order curvature terms to avoid a Big Rip singularity, and approaches to modifying gravity which leads to a late-time accelerated expansion without recourse to a new form of dark energy.
