Income Distribution in Macroeconomic Models


Book Description

This book looks at the distribution of income and wealth and the effects that this has on the macroeconomy, and vice versa. Is a more equal distribution of income beneficial or harmful for macroeconomic growth, and how does the distribution of wealth evolve in a market economy? Taking stock of results and methods developed in the context of the 1990s revival of growth theory, the authors focus on capital accumulation and long-run growth. They show how rigorous, optimization-based technical tools can be applied, beyond the representative-agent framework of analysis, to account for realistic market imperfections and for political-economic interactions. The treatment is thorough, yet accessible to students and nonspecialist economists, and it offers specialist readers a wide-ranging and innovative treatment of an increasingly important research field. The book follows a single analytical thread through a series of different growth models, allowing readers to appreciate their structure and crucial assumptions. This is particularly useful at a time when the literature on income distribution and growth has developed quickly and in several different directions, becoming difficult to overview.




Modeling Income Distributions and Lorenz Curves


Book Description

Jean-Jacques Rousseau wrote in the Preface to his famous Discourse on Inequality that “I consider the subject of the following discourse as one of the most interesting questions philosophy can propose, and unhappily for us, one of the most thorny that philosophers can have to solve. For how shall we know the source of inequality between men, if we do not begin by knowing mankind?” (Rousseau, 1754). This citation of Rousseau appears in an article in Spanish where Dagum (2001), in the memory of whom this book is published, also cites Socrates who said that the only useful knowledge is that which makes us better and Seneca who wrote that knowing what a straight line is, is not important if we do not know what rectitude is. These references are indeed a good illustration of Dagum’s vast knowledge, which was clearly not limited to the ?eld of Economics. For Camilo the ?rst part of Rousseau’s citation certainly justi?ed his interest in the ?eld of inequality which was at the centre of his scienti?c preoccupations. It should however be stressed that for Camilo the second part of the citation represented a “solid argument in favor of giving macroeconomic foundations to microeconomic behavior” (Dagum, 2001). More precisely, “individualism and methodological holism complete each other in contributing to the explanation of individual and social behavior” (Dagum, 2001).




Income Distribution, Inflation, and Growth


Book Description

Structuralist macroeconomics has emerged recently as the only viable theoretical alternative for economists and practitioners in developing countries. Lance Taylor's innovative work represents a landmark in this field. It codifies a new generation of structuralist macroeconomic models that incorporate the economic power relationships of key institutions and groups, integrates both finance and real macroeconomics, and covers a diverse range of experience in the developing world over the past three decades. In an introduction Taylor explains his methodology, describes assumptions underlying the models used, and reviews theories that relate economic growth and the role of financial assets. He then takes up basic structuralist models of a closed economy and moves on to consider the open economy cases. He incorporates the latest developments in the field (inflation, financial crisis, exchange rate management, increasing returns, and the like) in a treatment that departs substantially from economic orthodoxy. Taylor first addresses the question of how to specify "closure" or define the causal structure of macro models. He also considers how income redistribution influences growth and output and how income redistribution interacts with inflation. Next, an investment-driven non-full employment growth model draws on ideas introduced earlier to illustrate how different sorts of macroeconomic policies affect short-run adjustment and growth prospects over time. Taylor then turns to the problems proposed by economic openness in a stylized semi-industrialized country, starting with international trade. A fix-price/flex-price model is developed, and additional models demonstrate cases of policy relevance as well as interactions between class conflict and growth.




Income Modeling and Balancing


Book Description

​This book presents a rigorous treatment of the mathematical instruments available for dealing with income distributions, in particular Lorenz curves and related methods. The methods examined allow us to analyze, compare and modify such distributions from an economic and social perspective. Though balanced income distributions are key to peaceful coexistence within and between nations, it is often difficult to identify the right kind of balance needed, because there is an interesting interaction with innovation and economic growth. The issue of justice, as discussed in Thomas Piketty’s bestseller “Capital in the Twenty-First Century” or in the important book “The Price of Inequality” by Nobel laureate Joseph Stiglitz, is also touched on. Further, there is a close connection to the issue of democracy in the context of globalization. One highlight of the book is its rigorous treatment of the so-called Atkinson theorem and some extensions, which help to explain under which type of societal utility functions nations tend to operate either in the direction of more balance or less balance. Finally, there are some completely new insights into changing the balance pattern of societies and the kind of coalitions between richer and poorer parts of society to organize political support in democracies in either case. Oxford University's Sir Tony Atkinson, well known for his so-called Atkinson theorem, writes in his foreword to the book: “[The authors] contribute directly to t he recent debates that are going on in politics. [...] with this book the foundation of arguments concerning a proper balance in income distribution in the sense of identifying an ‘efficient inequality range’ has got an additional push from mathematics, which I appreciate very much.”




Economic Inequality and Income Distribution


Book Description

Economic inequality has become a focus of prime interest for economic analysts and policy makers. This book provides an integrated approach to the topics of inequality and personal income distribution. It covers the practical and theoretical bases for inequality analysis, applications to real world problems and the foundations of theoretical approaches to income distribution. It also analyses models of the distribution of labour earnings and of income from wealth. The long-run development of income - and wealth - distribution over many generations is also examined. Special attention is given to an assessment of the merits and weaknesses of standard economic models, to illustrating the implications of distributional mechanisms using real data and illustrative examples, and to providing graphical interpretation of formal arguments. Examples are drawn from US, UK and international sources.




Income Inequality and Poverty


Book Description

Deals with income distribution methods and their economic applications.




Input-Output Analysis and the Structure of Income Distribution


Book Description

The purpose of this study is in keeping with the shift in concern over the eco nomic problems of growth to those of income distribution in recent years. Income distribution problems may be analyzed by not only the traditional procedures, but also by some extensions of the input-output technique as I shall demonstrate in this volume of the Lecture Notes. Some fruitful results are obtained by applying the extended input-output technique to income analysis as well as to output analysis. This volume consists of three parts. These parts may be viewed along two veins, with some overlapping unavoidable: (1) Parts One and Two contain extensions of the input-output analysis and (2) Parts One and Three contain studies of the effects of the structure of income distribution on some other economic relationships. First, as an extension of the input-output analysis, we present a synthesis of the Leontief interindustry matrix multiplier and the Keynesian income multiplier in disaggregated form, and introduce a new concept which may be called the "Interrela tional Income Multiplier" as a matrix. It is designed to analyze the interrelation ships among various income-groups in the process of income formation through the medium of industrial production activity. Although this multi-sector multiplier follows from Leontief's interindustry matrix multiplier, it is formulated by the inclusion of the income generation process, which is omitted in the usual input output open model, and by projecting the multiplier process into not only the output determination side, but also into the income-determination side.




Testing Piketty’s Hypothesis on the Drivers of Income Inequality


Book Description

Thomas Piketty's Capital in the Twenty-First Century puts forth a logically consistent explanation for changes in income and wealth inequality patterns. However, while rich in data, the book provides no formal empirical testing for its theoretical causal chain. In this paper, I build a set of Panel SVAR models to check if inequality and capital share in the national income move up as the r-g gap grows. Using a sample of 19 advanced economies spanning over 30 years, I find no empirical evidence that dynamics move in the way Piketty suggests. Results are robust to several alternative estimates of r-g.




Income Distribution Dynamics of Economic Systems


Book Description

Econophysics has been used to study a range of economic and financial systems. This book uses the econophysical perspective to focus on the income distributive dynamics of economic systems. It focuses on the empirical characterization and dynamics of income distribution and its related quantities from the epistemological and practical perspectives of contemporary physics. Several income distribution functions are presented which fit income data and results obtained by statistical physicists on the income distribution problem. The book discusses two separate research traditions: the statistical physics approach, and the approach based on non-linear trade cycle models of macroeconomic dynamics. Several models of distributive dynamics based on the latter approach are presented, connecting the studies by physicists on distributive dynamics with the recent literature by economists on income inequality. As econophysics is such an interdisciplinary field, this book will be of interest to physicists, economists, statisticians and applied mathematicians.
