Redistribution and entrepreneurship with Schumpeterian growth

We examine the effects of redistributive taxation on growth and inequality in a Schumpeterian model with risk-averse agents. There are skilled and unskilled workers, and the growth rate is determined by the occupational choice of skilled agents between entrepreneurship and employment. We show that redistribution provides insurance to entrepreneurs and increases the growth rate. The effects on inequality are such that low tax rates increase inequality relative to laissez-faire due to changes in wages, but higher tax rates can simultaneously raise growth and reduce inequality. We contrast the optimal linear income tax with alternative policies for promoting R&D and find that it is preferable on both equity and efficiency grounds.      

When income differences hurt or excite: The nonlinear effect of regional inequality on subjective wellbeing

Combining information from the European Union Statistics on Income and Living Conditions and the European Social Survey, we investigate the relationship between subjective well-being and income inequality using regional inequality indicators and individual data. We assume that inequality aversion and perception of social mobility affect the impact of regional inequality on subjective well-being in opposite directions. We find evidence of an inverse U-shaped effect of inequality, where inequality starts to have a positive effect on subjective well-being that becomes negative with a switch point before the average of the Gini index for the entire sample. The rationale for our nonlinear finding is that Hirschman's tunnel effect (and the positive effect of perceived social mobility) prevails for low levels of inequality, while inequality aversion and negative relative income effects are relatively stronger when inequality is higher. Robustness checks on different sample splits are consistent with the hypothesis of the two drivers.     

TESTING FOR MULTIPLE BUBBLES: LIMIT THEORY OF REAL‐TIME DETECTORS

This article provides the limit theory of real‐time dating algorithms for bubble detection that were suggested in Phillips, Wu, and Yu (PWY; International Economic Review 52 [2011], 201–26) and in a companion paper by the present authors (Phillips, Shi, and Yu, 2015; PSY; International Economic Review 56 [2015a], 1099–1134. Bubbles are modeled using mildly explosive bubble episodes that are embedded within longer periods where the data evolve as a stochastic trend, thereby capturing normal market behavior as well as exuberance and collapse. Both the PWY and PSY estimates rely on recursive right‐tailed unit root tests (each with a different recursive algorithm) that may be used in real time to locate the origination and collapse dates of bubbles. Under certain explicit conditions, the moving window detector of PSY is shown to be a consistent dating algorithm even in the presence of multiple bubbles. The other algorithms are consistent detectors for bubbles early in the sample and, under stronger conditions, for subsequent bubbles in some cases. These asymptotic results and accompanying simulations guide the practical implementation of the procedures. They indicate that the PSY moving window detector is more reliable than the PWY strategy, sequential application of the PWY procedure, and the CUSUM procedure.     

Inequality and the business cycle: evidence from U.S. survey data

ABSTRACT

We study the effects of macroeconomic shocks on measures of economic inequality obtained from U.S. survey data. To identify aggregate supply, aggregate demand, and monetary policy shocks, we estimate vector autoregressions and impose sign and zero restrictions on impulse response functions. We find that the effects of the macroeconomic shocks on inequality depend on the type of shock as well as on the measure of inequality considered. Contractionary monetary policy shocks increase expenditure and consumption inequality, whereas income and earnings inequality are less affected. Adverse aggregate supply and demand shocks increase income and earnings inequality, but reduce expenditure and consumption inequality. Our results suggest that different channels dominate in the transmission of the shocks. The earnings heterogeneity channel is consistent with the inequality dynamics after monetary policy shocks, but it appears to be less crucial when the economy is hit by either aggregate supply or aggregate demand shocks. Using variance decompositions, we find that although the macroeconomic shocks account for large shares of the variation in the macroeconomic variables, their contributions to the dynamics of the inequality measures are limited.     

中国农村的收入差距与健康

随着收入差距的扩大,收入分配对健康和健康不平等的影响日益受到关注。本文利用中国健康营养调查(CHNS)1997年和2000年农村的面板数据回答两个问题:收入差距对健康的影响以及影响健康的方式;收入差距的扩大是否会导致健康不平等的加剧,尤其是低收入人群的健康是否受到更为不利的影响。研究发现,首先收入差距对健康的影响存在滞后效应;其次,收入差距对健康的影响呈现“倒U”型,在收入差距较高时,收入差距对健康的影响主要为负向的,一个可能的原因是收入差距影响到公共卫生设施的供给。再次,收入差距的扩大会加强收入效应,其含义是如果低收入人群的收入更容易受到负向冲击,那么收入差距对低收入人群的健康更为不利。     

Statistical analysis of inequality with decompositions: the Canadian experience

This study carries out a decomposition of Theil-entropy measures into a between-group component, based on factors such as education, age, gender, and marital status, and a component representing inequality within each group. We apply a bootstrapping technique to measures of inequality to enable statistical inference. Trends in household income inequality in Canada are investigated using data from 1991 to 1997 drawn from Survey of Consumer Finance. We find an evident trend toward increasing inequality of household incomes between the years 1991–1997, during which the economy was recovering from a steep recession. Although most of the increase in measured inequality is attributed to the `within-group' component, we find the change in `between-group' inequality to be significant for education, age, and marital status.

Income, income inequality, and health: Evidence from China

This paper tests using survey data from China whether individual health is associated with income and community-level income inequality. Although poor health and high inequality are key features of many developing countries, most of the earlier literature has drawn on data from developed countries in studying the association between the two. We find that self-reported health status increases with per capita income, but at a decreasing rate. Controlling for per capita income, we find an inverted-U association between self-reported health status and income inequality, which suggests that high inequality in a community poses threats to health. We also find that high inequality increases the probability of health-compromising behavior such as smoking and alcohol consumption. Most of our findings are robust to different measures of health status and income inequality. Journal of Comparative Economics 34 (4) (2006) 668–693.     

A numerical simulation analysis of (Hukou) labour mobility restrictions in China

We use numerical simulation methods to analyze the Hukou system of permanent registration in China which many believe has supported growing relative inequality over the last 20 years by restraining labour migration both between the countryside and urban areas and between regions and cities. Our aim is to inject economic modelling into the debate on sources of inequality in China which thus far has been largely statistical. We first use a model with homogeneous labour in which wage inequality across various geographical divides in China is supported solely by quantity based migration restrictions (urban–rural areas, rich–poor regions, eastern-central and western (non-coastal) zones, eastern and central-western development zones, eastern–central–western zones, more disaggregated 6 regional classifications, and an all 31 provincial classification). We calibrate this model to base case data and when we remove migration restrictions all wage and most income inequality disappears. Results from this model structure points to a significant role for Hukou restrictions in supporting inequality in China. We then present a further model extension in which urban house price rises retard rural–urban migration. The impacts of removing Hukou restrictions on migration are smaller, but are still significant. Finally, we modify the model to capture labour productivity differences across regions, calibrating the modified model to estimates of both national and regional Gini coefficients. Removal of migration barriers is again inequality improving but less so.     

The Great Recession and Racial Inequality: Evidence from Measures of Economic Well-Being

Abstract:

The Great Recession had a tremendous impact on low-income Americans, in particular Black and Latino Americans. The losses in terms of employment and earnings are matched only by the losses in terms of real wealth. In many ways, however, these losses are merely a continuation of trends that have been unfolding for more than two decades. We examine the changes in overall economic well-being and inequality, as well as changes in racial economic inequality during and since the Great Recession. We find that the Levy Institute Measure of Economic Well-Being inequality between White and Black households decreased during the Great Recession but since 2010, racial inequality in terms of LIMEW has increased. We find that changes in base income, taxes, and income from non-home wealth during the Great Recession produced declines in overall inequality, while only taxes reduced between-group racial inequality.     

The saving–growth–inequality triangle in China

China's fast growth is perceived as a major determinant of its savings glut that contributes to global imbalances, but China's income inequality has been largely overlooked as the economy moves rapidly toward the Kuznets curve peak. This paper provides a new explanation for the complex issue of Chinese saving using a structural vector autoregressive (SVAR) model. We find that China's growth is positively affected by saving but has a limited effect on saving, that inequality mainly has a negative impact on growth but has a positive impact on saving, and that inequality is a stronger factor than growth in explaining high saving. Therefore, inequality must be mitigated to lower the high saving rate in China, and growth will be unaffected by lowering both inequality and saving.     

Income Distribution and Aggregate Saving: A Non‐Monotonic Relationship

Drawing on a panel of advanced economies, this paper documents a concave and non‐monotonic link between inequality and the aggregate household saving rate. We find that, at a low level of inequality, more inequality is associated with higher saving; but we also show that a negative relationship between inequality and saving prevails where inequality is high. Using different empirical approaches, we locate the turning point, where the marginal effect of inequality turns from positive to negative, at a net income Gini coefficient of around 30. Moreover, we show that the relationship between inequality and saving also depends on financial market conditions. While inequality increases saving, when credit is scarce it tends to reduce saving at high levels of credit. This paper primarily focuses on household saving, yet we also find some evidence for a non‐monotonic effect of inequality on private saving, national saving, and the current account balance.     

Do dictatorships redistribute more?

This paper examines the effect of political institutions on fiscal redistribution for a country-level panel from 1960–2010. Using data on Gini coefficients before and after government intervention, we apply a measure of effective fiscal redistribution that reflects the effect of taxes and transfers on income inequality. Our findings clearly indicate that non-democratic regimes demonstrate significantly greater direct fiscal redistribution. Subsequently, we employ fiscal data in an attempt to enlighten this puzzling empirical finding. We find that dictatorial regimes rely more heavily on cash transfers that exhibit a direct impact on net inequality and consequently on the difference between market and net inequality (i.e., effective fiscal redistribution), whereas democratic regimes devote a larger amount of resources to public inputs (health and education) that may influence market inequality but not the difference between market and net inequality per se. We argue that the driving force behind the observed differences within the pattern on government spending and effective fiscal redistribution is that democratic institutions lead survival-oriented leaders to care more for the private market, and thus to follow policies that enhance the productivity of the whole economy.     

MEASURING INEQUALITY WITHIN THE HOUSEHOLD

The purpose of this paper is to explore a number of measures of inequality within households. We focus primarily on two types of inequality, first, inequality in money incomes, second, inequality in control over household resources. Control is measured in two ways: first, as control over the management of household finances and, second, as influence over household decision-making. We discuss arguments for and against each of the measures of inequality, and compare the measures against one another in terms of the level of inequality each measure finds. The paper does not attempt to explain inequality; instead, its aim is to discuss the question “What is it that we wish to explain?”

A political economy perspective on persistent inequality,inflation, and redistribution

In this paper we examine the dynamics of the link between inequality and inflation from a political economy perspective. We consider a simple dynamic general equilibrium model in which agents vote over the desired inflation rate in each period, and inequality is persistent. Inflation in our model is a mechanism of redistribution, and we find that the link between inequality and inflation within any period or over time depends on institutional and preference related parameters. Furthermore, we find that differences in the initial distributions of wealth can yield a diverse set of patterns for the evolution of the inflation and inequality link. Relative to existing literature, our model leads to more precise predictions about the inflation–inequality correlation. To that end, results in the extant empirical literature on the inflation and inequality link need to be interpreted with caution.     

Income Distribution and Demand-Induced Innovations

We introduce non-homothetic preferences into an innovation-based growth model and study how income and wealth inequality affect economic growth. We identify a (positive) price effect—where increasing inequality allows innovators to charge higher prices and (negative) market-size effects—with higher inequality implying smaller markets for new goods and/or a slower transition of new goods into mass markets. It turns out that price effects dominate market-size effects. We also show that a redistribution from the poor to the rich may be Pareto improving for low levels of inequality.     

ECONOMIC FREEDOM & HAPPINESS INEQUALITY: FRIENDS OR FOES?

This article examines the relationship between economic freedom and happiness inequality for a large sample of countries. We find that economic freedom is negatively associated with happiness inequality and robust to several alternative measures of happiness inequality, including the standard deviation, mean absolute difference, coefficient of variation, and Gini coefficient. Among the economic freedom areas, legal system and sound money are negatively correlated with happiness inequality. Drawing on the Engerman‐Sokoloff hypothesis, we use a measure of factor endowments as an instrument for economic freedom to provide a further robustness test, finding a negative association between economic freedom and happiness inequality.

Differential mortality and social security

Abstract This paper studies the normative problem of redistribution between individuals who differ in their lifespans. We discuss aspects related to the objective function and argue that aversion to multiperiod inequality should be taken into account. Then, we study the properties of the social optimum both with full information and with asymmetric information. We highlight the role of aversion to multiperiod inequality and show that it has substantial consequences on the design of Social Security schemes. In particular, we show that for a low (resp. high) aversion to multiperiod inequality, a negative (resp. positive) implicit tax rate on continued activity is desirable.     

Income inequality among minority farmers in China: Does social capital have a role?

We used recently available household panel data collected by China's National Bureau of Statistics to examine the effects of natural, human, material, and social capital on income inequality among minority farmers in China's Xinjiang Province between 2011 and 2012. Results obtained from panel quantile regression and correlated random effects’ models show that income inequality and the poverty of ethnic farmers have been decreasing to some extent. Results also indicated that human capital exacerbates income inequality among the minorities, whereas the effect of natural capital on income inequality is not evident. Social and material capital reduce income inequality among ethnic minorities. Results from the decomposition of the Gini coefficient indicate that material and social capital contribute to a substantial majority of the income inequality in the region.     

Institutions and training inequality

We analyze how firm-provided training is affected by the interaction among important institutional variables in the labor market: firing costs, minimum wages and unemployment benefits. We find that the degree of complementarity and substitutability among these variables depends on employees' abilities. Thereby the institutional interactions influence skill inequality. We derive how the influence of one of the institutional variables above is affected by other institutional variables with respect to inequality in skills arising from firm-provided training. We derive several striking results, such as: (a) the minimum wage and unemployment benefits generate increasing skill inequality whereas firing costs generate skill equalization; (b) unemployment benefits and firing costs are complements in their effects on skill inequality, (c) firing costs and the minimum wage are substitutes in their effects on skill equalization, and (d) unemployment benefits and the minimum wage are substitutes in their effects on skill inequality.     

Political capitalism: The interaction between income inequality,economic freedom and democracy

We study the relationship between income inequality and economic freedom for a panel of 100 countries for the 1971–2010 period. Using a panel Granger non-causality approach, we reject the null hypothesis of Granger non-causality running from income inequality to economic freedom, but not vice versa. From a series of dynamic panel estimations we show that the effect of income inequality on economic freedom is negative and robust to the inclusion of additional controls. In particular, inequality is negatively associated with those components of economic freedom related to international trade, domestic market regulation as well as the rule of law and property rights protection. We argue that the negative effect of inequality on economic freedom is due to the economic elite converting its economic power into de facto political power to defend its economic interests; these interests run counter to economic freedom, discouraging innovation and competition as well as protecting the elite's rents. Finally, we show that economic freedom decreases with income inequality even in democratic countries, suggesting that democratic institutions do not prevent economic freedom from eroding. We argue that the latter finding corresponds to a system of political capitalism or captured democracy, where a powerful economic elite can nevertheless exercise de facto political power by cooperating with politicians and other decision-makers for their mutual benefit.
