Inequality of Income and Wealth Distribution in Nepal Inequality of Income and Wealth Distribution in Nepal Presented by Sunil Narsingh Rajbhandari Submitted for the degree of Ph.D. in Economics at Faculty of Economics University of Lugano Lugano, Switzerland Mauro Baranzini, supervisor, University of Lugano, Switzerland Heinrich Bortis, University of Fribourg, Switzerland Pietro Balestra, University of Lugano, Switzerland Lugano, March 2005 To my family ABSTRACT This dissertation focuses on the economic inequality problem in Nepal, in particular, to integrate insights from other social aspects into the distribution problems of economic resources. It consists of five chapters on income and wealth distribution in Nepal. The first Chapter presents an overview of Nepal’s history, geography, economic development, policies and problems. The aim of Chapter Two is to provide an understanding of the inequality of income for 1984 and 1996 in Nepal and to describe how income/expenditure inequality in Nepal has changed during the period 1984 and 1996. In Chapter Three we examine the inequality of wealth distribution for 1995 and 1996 in Nepal. The Chapter four continues to investigate income and wealth inequalities using decomposition methods because they provide rigorous and powerful tools for identifying the underlying structure of income or wealth, which allow for direct interpretation of the estimated contribution in terms of the inequality index – the relative contribution of a set of population characteristics and of each income factor source that may be found within household income, expenditure and wealth. Chapter Five investigates the inequality of income in the process of development in Nepal. We first examine the Kuznets’ proposition according to which ‘the degree of inequality varies systematically with the level of income per head – initially increasing as incomes rise and then, beyond some point, decreasing, with further increases in income per head’. By considering historical, structural, institutional, political and socioeconomic issues, we offer an alternative explanation of reducing economic inequality in Nepal, with an emphasis on economic development. Key words: Income, wealth, inequality, economic development, inequality indexes INTRODUCTION 1 I THE BACKGROUND AND OBJECTIVE OF THE STUDY 1 II SUMMARY OF THE THESIS 5 III THE SIGNIFICANCE OF THE THESIS 16 CHAPTER 1 17 INTRODUCTION TO NEPAL 17 1.16H INTRODUCTION 17 1.1.1 Unification and the Background of the Shah Dynasty 18 1.1.2 Post Unification Political scenario and the Rana Regime 18 1.1.3 Modern history and politics 19 1.2 GEOGRAPHICAL DIVISION OF NEPAL 21 1.2.1 The Himalayan region 21 1.2.2 The Hills 21 1.2.3 The Terai region 22 1.2.4 The river system 24 1.3 THE POPULATION 25 1.4 CASTE AND ETHNICITY 31 1.5 THE INHERITANCE SYSTEM AND WOMEN'S COMMAND OVER RESOURCES 34 1.6 SOCIALISATION PATTERNS OF THE MALE AND FEMALE CHILD 36 1.7 RURAL SOCIETY AND KINSHIP 37 1.8 SOCIAL CLASSES AND STRATIFICATION 39 1.9 THE ECONOMY OF NEPAL 40 1.9.1 Agriculture 40 1.9.2 Non-agriculture 41 1.9.3 Income, consumption and saving 43 1.9.4 Distribution of productive assets and income 46 1.9.5 Poverty in Nepal 46 1.10 MOST RELEVANT CAUSES OF POVERTY IN NEPAL 48 1.10.1 The centrality of agriculture 48 1.10.2 The dearth of infrastructure 48 1.10.3 Low social indicators 49 1.10.4 Poor productivity of rural labour 49 i 1.10.5 Early stage in industrialisation 50 1.10.6 Late start in economic development 50 1.10.7 The unstable new democracy 51 1.10.8 Poor governance and increasing allegations of corruption 51 CHAPTER 2 52 THE CHANGING INCOME INEQUALITY IN NEPAL (1984-96) AND ITS COMPARISON WITH OTHER COUNTRIES OF SOUTH ASIAN ASSOCIATION FOR REGIONAL COOPERATION (SAARC) 52 2.1 INTRODUCTION 52 2.2 TOOLS OF ANALYSIS 53 2.3 THE LORENZ CURVE 54 2.3.1 The features of the Lorenz curve 56 2.3.2 The axiomatic approach 59 2.4 INEQUALITY MEASUREMENTS 61 2.4.1 The Gini coefficient 61 2.4.2 The Kuznets index 63 2.4.3 The Theil index 64 2.4.4 The Atkinson index 66 2.4.5 The variance of logarithms 70 2.4.6 Champernowne’s index 71 2.5 SENSITIVITY OF SELECTED INEQUALITY MEASUREMENTS 71 2.6 MEASURING THE TREND OF INCOME INEQUALITY IN NEPAL 82 2.7 MEASURING THE TRENDS OF INCOME INEQUALITY IN OTHER SAARC NATIONS 87 2.8 MEASURING INEQUALITY TRENDS IN BANGLADESH 1981-96 88 2.9 MEASURING INEQUALITY TRENDS IN INDIA 1981-96 96 2.10 MEASURING INEQUALITY TRENDS IN PAKISTAN 1985-97 106 2.11 MEASURING INEQUALITY TRENDS IN SRI LANKA 1980-95 113 2.12 COMPARISON OF NEPALESE INCOME INEQUALITY WITH OTHER SAARC COUNTRIES 120 2.13 CONCLUSIONS 131 2.14 DATA APPENDIX 133 2.15 APPENDIX 2A 135 2.16 APPENDIX 2B 139 ii CHAPTER 3 142 WEALTH DISTRIBUTION IN NEPAL 142 3.1 INTRODUCTION 142 3.2 AN OVERVIEW OF NEPAL LIVING STANDARD SURVEY (NLSS) 1996 143 3.3 WHAT ARE THE COMPONENTS OF NEPALESE FAMILY WEALTH?

A number of recent economic theories postulate that inequality might be necessary to generate extra savings required for fast growth. A number of new studies published in the 1990s have found a negative relationship between inequality and growth (see Alesina and Rodrik, 1994, Persson and Tabellini, 1994, Clarke 1995 etc). Deninger and Squire (1996) found a negative relationship between the unequal distribution of assets and growth. Aghion and Bolton (1991) have examined the effect of wealth inequality on growth in the presence of imperfect capital markets. In this latter context, poor people are liquidity constrained; which leads to a more unequal wealth distribution.

Baranzini, Claudia Rotondi and Roberto Scazzieri Excerpt More information 1 Resources, producibility and economic dynamics: a framework Mauro L. Baranzini, Claudia Rotondi and Roberto Scazzieri 1. Introduction 1.1 Resources in political economy The evolving relationship between the ownership and utilization of non- produced resources, the distribution of national income and wealth, and the formation and investment of capital funds within and across countries is a central feature in the structural dynamics of the world economy. Important features of that relationship have been a central focus of the theory of economic dynamics since Thomas Robert Malthus’s (1815a, 1815b), Edward West’s(1815)and David Ricardo’s(1817)analysisofdecreasing returns due to the emergence of scarcities and complementarities between productive inputs (which implies that the utilization of any given technique requires the maintenance of given propor- tions between those inputs). In Malthus’s, West’s and Ricardo’spioneering work, decreasing returns at the level of production units (such as the single productive establishment or the aggregate of production processes using a given non-produced resource) are associated with system-wise effects due to the interplay of (i) constraints due to the limited availability of non-produced and appropriable resources; (ii) the saving and accumulation behaviour of individ- uals and socio-economic groups; and (iii) income

  • Modigliani's Life-Cycle Theory of Savings Fifty Years Later*
    Modigliani’s life-cycle theory * of savings fifty years later MAURO BARANZINI 1. Introduction In the early 1950s Franco Modigliani, with Richard Brumberg and Albert Ando, formulated the life-cycle theory of consumption and savings that enjoyed a huge and undisputed success for at least three decades. It replaced Keynes’s ‘fundamental psychological law’ of savings, according to which the marginal and average propensities to save grow as income rises. On the other hand, the life-cycle theory maintains that the level of savings depends on the age of consumers, and hence on the demographic structure of society rather than on the level of family income. But, since the early 1980s, the life-cycle theory has increasingly come under attack, for at least four reasons. One reason is the exis- tence of an important inter-generational transmission of wealth, to be imputed to motives that are exogenous to the life-cycle model. The second reason is the growing evidence that the rich continue to save more than the less fortunate, as Keynes in fact maintained. The third reason is that there is growing evidence, at least in Western Europe and Japan, that young families in their twenties and thirties save a positive and increasing proportion of their income, which is in sharp –––––––––– University of Lugano, Lugano (Switzerland) and City of Cambridge; e-mail: [email protected]. * I am grateful to GianPaolo Mariutti, Roberto Scazzieri, Giandemetrio Maran- goni and other colleagues for helpful discussion and criticism of earlier drafts of this paper.

  • Markets, Money and Capital : Hicksian Economics for the Twenty-First
    This page intentionally left blank Markets, Money and Capital Sir John Hicks (1904–89) was a leading economic theorist of the twen- tieth century, and along with Kenneth Arrow was awarded the Nobel Prize in 1972. His work addressed central topics in economic theory, such as value, money, capital, and growth. An important unifying theme was the attention to economic rationality ‘in time’ and his acknowledg- ment that apparent rigidities and frictions might exert a positive role as a buffer against excessive fluctuations in output, prices, and employment. This emphasis on the virtue of imperfection significantly distances Hicksian economics from both the Keynesian and monetarist approaches. Containing contributions from distinguished theorists in their own right (including three Nobel Prize-winners), this volume examines Hicks’s intellectual heritage and discusses how his ideas sug- gest a distinct approach to economic theory and policy-making. It will be of great interest to scholars and students of economic theory and the history of economic thought. roberto scazzieri is Professor of Economics at the University of Bologna, a Senior Member of Gonville and Caius College and Life Member of Clare Hall, Cambridge. amartya sen is a Nobel laureate and Professor of Economics and Philosophy at Harvard University. stefano zamagni is Professor of Economics at the University of Bologna and Adjunct Professor of International Economics at Johns Hopkins University.

  • Profit Theory: a New Macroeconomic Analysis Andrea Carrera
    Profit theory: a new macroeconomic analysis Andrea Carrera Faculty of Economics Università della Svizzera italiana Lugano, Switzerland A thesis submitted for the degree of Doctor of Philosophy in Economics Lugano, September 2016 Doctoral Committee: Prof. Alvaro Cencini (Università della Svizzera italiana) Prof. Patrick Gagliardini (Università della Svizzera italiana) Prof. Louis-Philippe Rochon (Laurentian University, Canada) Prof. Sergio Rossi (University of Fribourg, Switzerland) Abstract Profit and its investment in productive activities lie at the heart of modern monetary economies. Indeed, it is thanks to profit investment that fixed capital is produced and used by companies to increase the number of consumption goods and, ultimately, to increase the wealth of households. Yet, despite economists’ full understanding of corporate gains from a microeconomic standpoint, economists are far from sharing a common theory of macroeconomic profit. In this book, an assessment is made of profit theories since 1874, the year that marked the advent of so-called mainstream economics. Following an analysis of bank money, a discrete-time theory of profit formation and economic growth is then proposed. Possibly the main conclusion of this inquiry, mone- tary authorities should distinguish distributive payments from those transactions that define the creation of new income. Thus, a reform of the system of national payments is advocated, aiming to keep record of all production-based wealth. Keywords: production; consumption; investment; monetary systems;
