Statistical Mechanics of Income in Peripheral Capitalism: Peru, 2004-2022

Abstract

This paper studies the evolution of gross household income in Peru between 2004 and 2022.
The paper aims at using the maximum entropy method and the info-metrics approach to
identify the shape of the income distribution for Peruvian capitalism. Based on data from
Peruvian National Household Surveys (ENAHO) and the Luxembourg Income Study (LIS),
I estimate a statistical model (a mixture of densities) fitting the Peruvian distribution of
household income. Based on previous literature, I describe how income shares at the bottom
of the distribution follow exponential and log-normal densities, while top income shares
replicate a Pareto distribution. As it is documented for some advanced economies, these
shapes are determined by the structural and institutional features of capitalism. While the
exponential distribution mirrors the competition for wages that happens in capitalist labor
markets, the Pareto distribution represents the competition of capitalists for rates of return
for capital. Finally, I utilize the aforementioned mixture density as a likelihood function
and propose a parametric form for the Lorenz curve. That allows me to construct further
inferences over the effects of redistribution among the household sector (i.e., a comparison of
pre-tax and post-tax income) and the effects over homoplutia (i.e., the proportion of households
located in both the 10th decile of wages and the 10th decile of profit). I found that (i)
the capitalist structure restrains the improvement of Peruvian households at the bottom of
income distribution, and (ii) homoplutia does not increase because of the high concentration
of rental income at the Pareto tail.

Revisiting Class Dynamics: Mobility, Inequality, and Social Polarization in the U.S.

Abstract

Empirical and theoretical work on class polarization uses proxy variables such as educational attainment or level of income to depict class status which do not necessarily reflect conflict between agents. Bowles (2004) proposes an analytical framework where using observed measures, a consistent definition of social class is obtained which reflects agents' access to leisure through each other's labor. Using this approach and panel data from PSID, this study analyzes social polarization indices, class mobility, and its relationship to inequality in the US.

Regional Differences of the Inequality of Opportunity and Income Mobility in Korea

Abstract

The purpose of this study is to analyze the regional differences of the inequality of opportunity and income mobility in Korea and to develop empirical approaches to its causes. In particular, we focus on social experimental research design and big data, which have recently been emphasized in social sciences, to identify regional factors affecting the income mobility and explore empirical methods suitable for the data availability in Korea.
It is well known that Korea's birth rate is the lowest in the world. Income inequality, spatial segregation, and income mobility interact with each other and threaten the future of the society. Also, the severe competition in the metropolitan area leads to low inter-generational income mobility, which results in the parents’ choice to reduce the number of children in order to focus human capital investment on their children with limited resources. This study is expected to provide various policy implications by identifying how regional inequality of opportunity is related to various regional characteristics such as income inequality or spatial segregation, etc.

Potential Impact of Employment on Time and Income Poverty in the U.S.

Abstract

The official poverty rate for the United States in 2022 was 11.5 percent, meaning nearly 38 million people were poor. The rate using the Supplemental Poverty Measure (SPM) was even higher, at 12.4 percent. While SPM is an improvement over the official measure in a number of ways, it still implicitly assumes the presence of a full-time unpaid worker in the household doing the work of social reproduction. The Levy Institute of Time and Income Poverty (LIMTIP) accounts for the amount of time that households at or near the poverty threshold need to reproduce themselves. We produce estimates of the LIMTIP for the US for the period from 2005 to 2022. We find that poverty is both more extensive and deeper than the official or SPM measures tell us. Is an increase in employment the solution to poverty in the US? We examine the impact that employment might have on poor households by assigning non-employed adults in time-adjusted income poor households the jobs that they are likeliest to get in the current labor market. We then assess the impact of that employment on time and income poverty. We find that the increase in time deficits induced by increased time spent on paid employment significantly attenuates the income poverty-reducing effects of increased earnings.
