Linking functional with personal income distribution: a stock-flow consistent approach

© 2015 Taylor & Francis. This paper develops a benchmark stock-flow consistent model that links functional with personal income distribution. The model consists of various household groups that receive income from different sources or from the same sources in different proportions. The dynamic linkage between functional and personal income distribution is formulated as part of a complete macroeconomic system. Inequality decomposition techniques are employed to associate income sources with personal income distribution. Simulation exercises are conducted to reveal the various ways through which functional and personal income distribution interact. In the simulations, a rise in the exogenous component of low-skilled workers’ wage share reduces inequality in the short run; in the medium to long run inequality starts increasing due to certain macroeconomic developments, but remains lower than its initial level in almost all cases. A change in functional income distribution due to a rise in the dividend payout ratio of firms increases inequality both in the short run and the long run

Piketty's Calibration Economics: Inequality and the Dissolution of Solutions?

© 2015 Taylor & Francis. Abstract: By popularising interest in inequality, Thomas Piketty's Capital in the Twenty-First Century has made a significant contribution. It has helped to change the basic terms of debate regarding wealth and income. However, Capital exhibits several weaknesses. The overall statement of Piketty's 3 laws tends to confuse the reader by conflating capital with all forms of wealth, and capital with the current market valuation of wealth assets. The whole creates a form of empiricism by metrics or calibration. The aggregation also lends itself to data as history rather than as historically grounded explanation of evidence. Concomitantly, it lacks a theorisation of capitalism, of power, of the state, of social movements, and of social transformations. This affects the way in which possible solutions to inequality are conceived. However, it does provoke further grounds for ethical counterargument productive of more progressive solutions to the problems it highlights

Tale of Two Ginis in the United States, 1921-2012

Following a methodology proposed by Jantzen and Volpert (2012), we use IRS Adjusted Gross Income (AGI) data for the United States (1921-2012) to estimate two Gini-like indices representing inequality at the bottom and the top of the income distribution. We also calculate the overall Gini index as a function of the parameters underlying the two indices. Our findings can be summarized as follows. First, we find that the increase in the Gini index from the mid 1940s to the late 1970s seems to be mostly explained by an increase in inequality at the bottom of the income distribution, which more than offsets the decrease in inequality at the top. The implication is that middle incomes gained relative to high incomes, but especially relative to low incomes. Conversely, it is rising inequality at the top that appears to drive the rise in the Gini index since 1981. Second, inequality at the top of the income distribution follows a U-shaped trajectory over time, similar to the pattern of the share of top incomes documented by Piketty and Saez (2003, 2006) and Atkinson, Piketty, and Saez (2011). Third, the welfare effects of the different forces behind an increasing Gini index can be evaluated in light of the Lorenz-dominance criterion proposed by Atkinson (1970): both top-driven and bottom-driven increases in the index appear not to imply strict Lorenz dominance by previous income distributions, and therefore are not associated with lower welfare in an absolute sense. In a relative sense, however, once average growth rates over the two periods are taken into account, the top-driven increase in inequality since 1981 appears to have been welfare reducing

Dualism and Macroeconomic Volatility

This paper develops a simple macroeconomic model that shows that combining capital market imperfections together with unequal access to investment opportunities across individuals can generate endogenous and permanent fluctuations in aggregate GDP, investment, and interest rates. Reducing inequality of access may be a necessary condition for macroeconomic stabilization. Moreover, countercyclical fiscal policies have a role to play: in our model savings are underutilized in slumps because of the limited debt capacity of potential investors. Therefore, the government should issue public debt during recessions in order to absorb those idle savings and finance investment subsidies or tax cuts for investors

What is Socialism Today? Conceptions of a Cooperative Economy

Socialism is back on the political agenda in the United States. Politicians and some economists who identify as socialists, however, do not discuss property relations, a topic that was central in the intellectual history of socialism, but rather limit themselves to advocacy of economic reforms, funded through taxation, that would tilt the income distribution in favor of the disadvantaged in society. In the absence of a more precise discussion of property relations, the presumption must be that ownership of firms would remain private or corporate with privately owned shares. This formula is identified with the Nordic and other western European social democracies. In this article, I propose several variants of socialism, which are characterized by different kinds of property relation in the ownership of society’s firms. In addition to varying property relations, I include as part of socialism a conception of what it means for a socialist society to possess a cooperative ethos, in place of the individualistic ethos of capitalist society. Differences in ethea are modeled as differences in the manner in which economic agents optimize. With an individualistic ethos, economic agents optimize in the manner of John Nash, while under a cooperative ethos, many optimize in the manner of Immanuel Kant. It is shown that Kantian optimization can decentralize resource allocation in ways that neatly separate issues of income distribution from those of efficiency. In particular, remuneration of labor and capital contributions to production need no longer be linked to marginal-product pricing of these factors, as is the key to efficiency with capitalist property relations. I present simulations of socialist income distributions, and offer some tentative conclusions concerning how we should conceive of socialism today

Changes in Economic Inequality in Europe and Latin America in the First Decades of the Twenty-First Century

This open access volume identifies the common and specific aspects of social mechanisms that generate inequalities, through comparative analyses of different dimensions in which inequalities are expressed. It includes studies on social inequalities in 5 European and 5 Latin American countries, along 11 thematic axes: inequalities in the labour market and labour trajectories; asymmetries in the relationship between training and employment; inequalities in work and family life; educational inequalities; geographical and social inequalities: ethnicity and language; social inequalities, migration and space; uncertainty, strategies, resources and capabilities; inequality of opportunity: intergenerational social mobility; social policies; gender inequalities; and research methodology. This volume is the result of a large collaborative project on social inequality funded by the European Commission: the International Network for Comparative Analysis of Social Inequalities. Taking into account diverse perspectives and approximations, the collaborators have created a general analytical framework as a model of analysis of social inequalities. The various contributions in this volume help readers gain a global outlook and help reflect on social inequalities in a comparative perspective. This volume addresses social science graduate and postgraduate students, researchers, social policy makers, as well as a broader academic audience interested in social inequality.Fil: Salvia, Hector Agustin.
