Income Distribution,Econophysics and Piketty

Piketty, Atkinson and Saez have put the analysis of income distribution back on center stage. The distinction between property income and labor income plays a central role in this framework. Property income derives from the rate of return on stocks of income-earning wealth and is more unequally distributed than labor income. Piketty argues that, because the rate of return (r) is generally greater than the rate of growth of the economy (g), property income tends to grow more rapidly than labor income, so that rising income inequality is an intrinsic tendency of capitalism despite interruptions due to world wars and great depressions. This article argues the exact opposite. The rise of unions and the welfare state were the fruits of long-term historical gains made by labor, and the postwar constraints on real and financial capital arose in sensible reaction to the Great Depression. The ‘neoliberal’ era beginning in the 1980s significantly rolled back all of these. The article uses the econophysics two-class argument of Yakovenko to show that we can explain the empirical degree of inequality using two factors alone: the profit share and the degree of financialization of income. The rise of inequality in the neoliberal era then derives from a reduction in the wage share (rise in the profit share) in the face of assaults on labor and the welfare state, and a sharp increase in the financialization of incomes as financial controls are weakened. These are inherently socio-political outcomes, and what was lost can be regained. Hence, there is no inevitable return to Piketty’s ‘patrimonial capitalism’.     

Real Minimum Wage and Growth Theory: Simulations and Some Policy Results

Abstract

A Solow type two‐sector growth model is used to examine several issues related to growth and unemployment in a minimum wage economy. By simulating the model, we demonstrate that given the same percentage increase in wage rate, an economy with a higher capital–labor ratio is more likely to decay. More importantly, a tariff policy reduces the unemployment periods by 92% provided that the current capital–labor ratio is one‐sixth of that of the steady state capital–labor ratio. We assume that the first best policy of uniform wage subsidy is not politically feasible.     

Economic development, growth of human capital, and the dynamics of the wage structure

In this paper I elucidate the sources of growth of human capital in the course of economic development. On the supply side (Section 1) I include the growth of family income, urbanization, the demographic transition, and the rising cost of time.The supply side alone cannot explain the continuous growth of human capital as it implies a self limiting decline in rates of return below those in alternative investments. Such declines are offset by growing demands for human capital in the labor market. Growth of demand for labor skills is a function of capital accumulation and of technological changes. Evidence on this hypothesis is summarized in Section 2 and on supply responses to growing demand for human capital in Section 3. Changes in the skill and wage structures in the labor market are an important part of the evidence.The reciprocal relation between economic growth and the growth of human capital is likely to be an important key to sustained economic growth. A caveat applies to indirect effects of economic growth on family instability, which may lead to a deterioration of childhood human capital in some sectors of society.     

China??s growth model and structural unbalance in the open economy

The Chinese economy has been significantly affected by the global financial crisis. Moreover, a rapid decline in growth rate can be mainly attributed to the expenditure structural unbalance, which takes root in its uneven national income distribution. Furthermore, the uneven national income distribution is the result of the extensive pattern of China’s economic growth in the open economy. The extensive pattern is characterized by labor-intensive export-led growth model. The need for high growth rate and fiscal revenue maximization forces local governments to compete against each other to get FDI by undervaluing production factors, resulting in the extensive pattern of growth. From an institutional point of view, uneven social power between government and public, central government and local governments, capital owners and labor force, and so on, can be viewed as the main reason for the extensive pattern of growth and uneven national income distribution. Low wage, which has been the main factor for the comparative advantage, now turns out to be barriers to boosting domestic demand. The technology lag in the manufacturing industry also has a significant negative impact on improving labor productivity and increasing per capita income. Hence, to deal with the recession, not only quantitative easing, but also structural adjustments are needed.     

The Minimum Wage and the Cause of Democracy

Too often the minimum wage is conceived of as a small policy measure that will be of benefit to only a small segment of the labor market while imposing costs on another segment of the labor market. Unexplored, however, are the larger philosophic questions that such a small measure may actually raise. One such issue is the relationship between the minimum wage and democratic principles. In this paper I argue that the minimum wage furthers the ends of democratic society in that low-wage workers may achieve greater equality of standing with their piers to the extent that income inequality is at all lessened; their autonomy as individuals is enhanced through higher wages, which in turn enables them to claim the benefits of citizenship and participate more effectively in the democratic process; and it fosters greater economic development in that it raises the overall structure of a region and perhaps the productivity of that region.

Employee Profit-sharing and Labor Extraction in a Classical Model of Distribution and Growth

This article sets out a classical model of economic growth in which the distribution of income features the possibility of profit-sharing with workers, as firms choose periodically between two labor-extraction compensation strategies. Workers are homogeneous with regard to labor power, and firms choose to compensate them with either only a conventional wage or a share of profits on top of this conventional wage. Empirical evidence shows that labor productivity (i.e. labor extraction) in profit-sharing firms is higher than labor productivity in non-sharing firms. The frequency distribution of labor-extraction employee compensation strategies and labor productivity across firms is time-variant, being driven by satisficing imitation dynamics from which we derive two significant results. First, heterogeneity in labor-extraction compensation strategies across firms, and hence earnings inequality across workers can be a stable long-run equilibrium outcome. Second, although convergence to a long-run equilibrium may occur with either a falling or increasing proportion of profit-sharing firms, the share of net profits in income and the rates of net profit, capital accumulation and economic growth nevertheless all converge to the highest possible long-run equilibrium values.     

Sources of crime in the state of Veracruz: The role of female labor force participation and wage inequality

Abstract

In recent years, crime has become a serious concern in Mexico as its increase has detrimentally affected government institutions and economic growth. There is considerable speculation among policy analysts about the causes of the increase in crime. Whereas some analysts attribute the increase to a rise in income inequality, others believe internal migration and a loss of morals are the roots of criminal behavior. This research shows that at least for the Mexican state of Veracruz, wage inequality and labor force participation have an important impact on crime. When gender is considered, however, the impact is more complicated than it seems. An increase in women's labor force participation decreases the overall number of alleged violent offenders. However, the number of alleged rapists and grievous bodily harm offenders increases as women's wage distribution improves. The results shed light on the gender dimensions of the economics of crime.     

Bonus pay for teachers,spatial sorting,and student achievement

Bonus pay policy for teachers in the U.S. is analyzed in this paper. We quantitatively argue that, because of the decentralized education finance system in the U.S., this policy may lead to higher teacher and household sorting across school districts. This then may lead to higher variance of achievement and lower mean achievement. Formally, we use an equilibrium political economy model of education at which households, heterogeneous in exogenously set income, and teachers, heterogeneous in exogenously set quality, are endogenously allocated across two school districts. Public education expenditures, which includes teachers’ wage payment and non-teacher related education spending, are financed through local income taxation. Income tax rate in each district is determined via majority voting. Achievement depends on the efforts chosen by teachers and non-teacher related education spending. Teacher efficiency wage per unit of quality is determined at the national teacher labor market. We first calibrate our benchmark model by matching certain statistics from the U.S. data. Then in a computational experiment, we introduce bonus pay for teachers which rises with average achievement. We find that for the recently observed level of average bonus pay (6.59% of average base salary), variance of achievement is 2.46% higher and mean achievement is 1.79% lower than the benchmark. Variance of achievement reaches its peak when average bonus pay is 14.06% and then it starts falling. Also, mean achievement always falls as average bonus pay rises.     

Heterogeneity in Ability and Inheritance,Disparities, and Development

This paper investigates the impact of income inequality on economic growth. A two-period overlapping generations model is developed where agents are heterogeneous in innate abilities and inheritance. In the first period, they receive their inheritance and their abilities are revealed. There are only two types of abilities: high and low. Individuals decide on their education level, and divide their inheritance between spending on education and saving. In the second period, individuals supply their labor and allocate the labor income and the return to their saving between consumption and bequests to their offsprings. Initial capital stock is owned entirely by the capitalists. In this context, a more equal distribution of income enhances economic growth if the economy is lower than a threshold capital-labor ratio, while income inequality has an insignificant effect above this threshold. The predictions of the model are tested empirically using the Hansen (1999) threshold estimation. The results, using a panel of 70 countries for the period 1971-1999, suggest that there is a statistically significant threshold income per capita, below which the coefficient on the relationship between inequality and economic growth is significantly negative and above which the estimate is not significant.     

The Meritocratic Elite vs. the Common Man: Income Inequality in the Affluent OECD Countries

Our goal is to highlight the relationship between vested interests of the meritocratic elite and the deteriorating situation of the common man. We provide an example of rising income inequality in selected OECD countries over the past thirty years. Income inequality is growing, despite the increase in labor productivity based on technological progress, which we prove by using robust panel regression models. Our findings could be explained by the effect of “extreme meritocracy” that describes a situation in which wages for “the working rich” are growing faster than their productivity, and creating wage stagnation for the middle-class workers.     

Adam Smith on the subordination of wage-earners in the commercial society

Abstract

Adam Smith's discourse on wage labour is both original for its time and complex. While Smith indisputably considered the substitution of serfdom by wage labour as an improvement in both opulence and independence, we argue that he nevertheless saw the wage relationship as one founded on subordination. We then cast light on the material factors and symbolic mechanisms which, in his writings, explain how and why the worker agrees to this subordination. Finally, we endeavour to show that Smith's praise for the system of natural liberty as well as his repeated criticisms of merchants and capital owners aimed to transcend this issue.     

最低工资制度能提高民营企业劳动收入占比吗

本文以民营企业要素投入行为为切入点,探讨最低工资制度对民营企业劳动收入占比的影响。基于2005-2008年和2011-2013年中国工业企业数据库民营企业面板数据的研究发现：最低工资制度提高了劳动密集型和资本密集型行业民营企业的劳动收入占比,降低了技术密集型民营企业的劳动收入占比。通过分解影响机制发现,最低工资制度提高了劳动密集型和资本密集型民营企业的工资水平,带来正向的收入效应,但也导致资本替代劳动,产生负向的替代效应。整体而言,最低工资制度提高了民营企业的劳动收入占比。为发挥最低工资制度对民营企业劳动收入占比的正向作用,继续调整最低工资标准、贯彻相关法规实施、提高劳动者技能水平成为重要措施。     

Green technological progress,agricultural modernization,and wage inequality: Lessons from China

Green technological progress (GTP) is crucial for environmental protection and economic growth in China. Over the past decades, China made huge GTP which exerts a far-reaching consequence on economic and social development. However, a paucity of research investigates the distributional effect of GTP. Meanwhile, we incorporate agricultural producer service sector into a three-sector general equilibrium model to reflect the modernization of small-scale agriculture. The agricultural producer service sector that acts as an intermediate sector can facilitate the utilization of intermediate inputs indirectly. To desalinate this process, a two-layer vertical production structure is established: parts of manufacturing goods are utilized by the service sector, outputs of which are intermediate inputs that could substitute labor in agriculture. Theoretical analysis shows that GTP increases both wage of skilled labor and unskilled labor. Nevertheless, GTP generates a greater impact on the wage of skilled labor than unskilled labor, leading to widening income disparity. Then, we examine the impact of GTP on wage inequality using a balanced panel data covering 30 provincial units in China during 2000–2019. In line with our theoretical conjecture, we find strong supportive evidences that GTP significantly widens the wage inequality.     

Optimal Redistributive Income Taxation and Efficiency Wages*

In this paper, we integrate efficiency wage setting with the theory of optimal redistributive income taxation. In doing so, we use a model with two skill types, where efficiency wage setting characterizes the labor market faced by the low‐skilled, whereas the high‐skilled face a conventional, competitive labor market. We show that the marginal income tax implemented for the high‐skilled is negative under plausible assumptions. The marginal income tax facing the low‐skilled can be either positive or negative, in general. An increase in unemployment benefits contributes to a relaxation of the binding self‐selection constraint, which makes this instrument particularly useful from the perspective of redistribution.     

Corporate profit tax,firm entry with unemployment,and income inequality

In this paper, we provide a general equilibrium analysis of corporate profit tax on income distribution, unemployment, and wage inequality. With firm dynamics in industrial sector, we identify a new channel through which profit tax affects income and wage inequality: profit tax cut will widen not only the wage gap between skilled and unskilled labor, but also exacerbate the wage inequality of unskilled labor among different sectors. The welfare effect of profit tax cut depends on unemployment deepening (labor-distortion effect) and more manufacturing firms enter the market (business-creation effect), eroding the market share of incumbent firms (business-stealing effect).     

劳动力市场的所有制分割与城乡收入差距

目前缺少系统的农民工工资的面板数据妨碍了对城镇劳动力市场的所有制分割如何影响城乡收入差距的研究。本文证明城镇集体经济部门的平均工资可以作为农民工工资的代理变量,并将城镇国有部门的平均工资与集体部门的平均工资的比例作为衡量城镇劳动力市场所有制分割的指标。笔者通过对中国1978—2008年间省际面板数据的回归分析发现,劳动力市场的所有制分割本身具有扩大城乡收入差距的效应,但是,非国有部门职工比重的增加会削弱所有制分割的影响,从而有助于缩小城乡收入差距。     

技术进步偏向对要素收入份额的影响——基于中国工业行业数据的研究

本文利用CES生产函数考察了技术进步偏向与资本一劳动收入份额比值之间的关系,并利用中国工业1979—2011年的数据进行了实证分析。估计结果表明：中国工业的要素替代弹性大于0小于1;资本增强型技术进步变化率小于劳动增强型技术进步变化率,1987年后工业技术进步为劳动节约型的,资本一劳动收入份额比值提高;资本深化、技术进步偏向、外商直接投资以及国际贸易是我国工业资本收入份额持续上升、劳动收入份额持续下降的主要原因,其中劳动节约型技术进步对要素收入份额失衡的影响最大。工业要素分配份额的演变直接体现了国民收入分配格局的失衡,也间接拉大了我国居民之间的收入差距。     

Classical political economy: the subsistence wage,and job guarantee concerns

Abstract:

In the theoretical framework of classical political economy, including the revisions of Marx and the more recent work of Piero Sraffa and others, the concept of the subsistence wage figures prominently. Here, following a recounting of this concept and demonstrating its significance not only for classical theory but also for larger social concerns, I argue that the “base wage” (as it is sometimes termed) as articulated within a “Job Guarantee” program, is (or should be) comparable to the subsistence wage but requires modification to make it (roughly) equivalent. It will be demonstrated that adherents of the classical approach did not rest their wage theory on a quasi-neoclassical supply–demand approach (with some primitive marginal productivity notion lying behind a supposed demand for labor schedule), but understood wages as socially determined where institutional and historic forces established a normative standard around which market wages gravitated. Such an approach was shared by, among others, Thorstein Veblen and John Maynard Keynes.     

Life beyond the Washington Consensus: An Introduction to Pro-poor Macroeconomic Policies

Abstract

This paper develops a rationale for the recession-induced inflation hypothesis. Within a conflicting claims framework we present a model in which both price leaders and organized workers set their nominal prices on the basis of a desired profit rate and a real wage target respectively. We argue that an absolute cost advantage in concentrated industries (for instance in fixed costs) may provide oligopolistic leaders sufficient margin to raise prices and restore a desired level of profitability during a recession. The resultizng unstable income distribution will set off an inflationary spiral if the firm's advantage in selling its output imparts an upward bias to the flexibility of input prices (specifically wages). Taking into consideration different scenarios for workers' bargaining power we present a simple simulation experiment to analyze the inflation and real wage paths of the economy after a negative output shock. When we endogenize output, we show that for a high degree of the bargaining power, output is likely to converge to a higher steady-state value.
