Convergence empirics across economies with (some) capital mobility

This paper uses a model of growth and imperfect capital mobility across multiple economies to characterize the dynamics of (cross-country) income distributions. This allows convenient study of the convergence hypothesis, and reveals, where appropriate, polarization and clumping within subgroups. The data show little cross-country convergence; instead, the important features are persistence, immobility, and polarization, exemplified by convergence club or twin peaks dynamics.     

Distribution Dynamics and Nonlinear Growth

This paper extends the distribution dynamics approach to the study of the shape of the growth process of a cross-section of countries. We first identify some empirical implications of a nonlinear Solovian growth model with multiple equilibria. These implications are then tested by a novel definition of the state space, which jointly considers income and growth rate. The main findings are that nonlinearity is a salient feature of the overall picture, and that the cross-section dynamics is compatible with the existence of multiple equilibria. We also discuss how the hypothesis of conditional convergence may be challenged in the light of our results.     

Conflict, Distribution and Population Growth

This paper studies an optimal foraging model where distributive conflicts among foragers emerge from population growth. It investigates distributive rules set to resolve the conflicts. Efficient distributive rules are the ones associated with the most efficient productive decisions. Unequal societies, where the ruling class or King maximizes the surplus, engender the choice of more efficient productive combinations and to a smaller population relative to egalitarian societies.     

Free Trade, Growth, and Convergence

Can trade liberalization have a permanent affect on output levels, and more important, does it have an impact on steady-state growth rates? The model emphasizes the role that knowledge spillovers emanating from heightened trade can have on income convergence and growth rates during transition and over the long run. Among the results of the model, unilateral liberalization by one country reduces the income gap between the liberalizing country and other, wealthier countries. From the long-run growth perspective, unilateral (and multilateral) liberalization generates a positive impact on the steady-state growth of all the trading countries.     

Income Distribution, Redistributive Politics, and Economic Growth

This article studies the political economy of inequality and growth by combining the political economy approach with an imperfect capital market assumption. In the present model, there emerges a class of individuals whose members do not invest privately beyond the state-financed schooling, due to their initial wealth constraint. We show that inequality affects private investment not only through the political effect, which relates inequality to private investment negatively, but also through what we call the threshold effect, which associates inequality to private investment positively. In general, private investment and inequality do not show a monotone negative relationship.     

From Malthus to Ohlin: Trade,Industrialisation and Distribution Since 1500

A recent endogenous growth literature has focused on the transition from a Malthusian world where real wages were linked to factor endowments, to one where modern growth has broken that link. In this paper we present evidence on another, related phenomenon: the dramatic reversal in distributional trends—from a steep secular fall to a steep secular rise in wage-land rent ratios—which occurred some time early in the 19th century. What explains this reversal? While it may seem logical to locate the causes in the Industrial Revolutionary forces emphasized by endogenous growth theorists, we provide evidence that something else mattered just as much: the opening up of the European economy to international trade.     

Endogenous Fertility, Income Distribution, and Growth

This article analyzes the interaction between growth and fertility via income distribution in a model in which fertility decisions are motivated by old-age support. It provides an explanation of the demographic transition of an economy from a stage of increasing fertility and low growth to a stage of low fertility, high human capital investments, and high growth.     

Reform,Growth, and Inequality in China*

This paper provides a survey of the literature on inequality in China – level, change, causes, and consequences. It attempts to answer six main questions. How much has inequality risen? What is its relation to poverty alleviation? What has happened to wealth inequality? What are the main dimensions of rising income inequality? The dimensions examined are: the rural–urban divide; urban labor market reform; regional divergence; rural–urban migration; and entrepreneurship, rent‐seeking, and corruption. Was it inevitable that inequality should rise so much? Does it matter that inequality has risen? Income distribution in China is bound up with both economic reform and economic growth. This paper concludes by considering the countervailing forces that will determine the path of inequality in future years.     

Towards Trade Equalisation: A Network Perspective on Trade and Income Convergence Across the Twentieth Century

An enduring dynamic of the twentieth century is the dramatic expansion of global trade with increased partners, goods, frequency and volumes. Most trade explanations such as the Heckscher–Ohlin, new trade theory, gravity models, and Ricardo and Sraffa focus on how bilateral import and export volumes and intermediate input goods are driven by decreased financial and information transaction costs. Extending work on trade flows and economic development, we derive several network measures of degree, betweenness and eigenvector centrality from dyadic trade flows from 1960 to 2009. We then empirically explore the interactive effects of trade connectivity, economic production and stages of development on income convergence and trade equalisation. We empirically find clear patterns towards a new phenomenon, both sigma levels and beta rates trade convergence and equalisation for our entire sample. Visualising sigma and beta convergence for seven major trading nations from 1920 to 2010, we believe offers new insights into economic development theory if only beginning to loosen the knot of trade, growth and globalisation.     

Public Capital and Economic Growth: A Convergence Approach

This paper estimates dynamic effects of public capital on output per capita. Based on an open economy growth model, I derive a version of the income convergence equation augmented with public capital. This equation is estimated using panel data of United States and Japanese regions. Sensible results are obtained when public capital is disaggregated into components. In both countries, the infrastructure component of public capital turns out to have significantly positive effects. The implied elasticity of output with respect to infrastructure is somewhere around 0.1 to 0.15. This suggests a modest contribution of infrastructure to postwar growth of the two countries.     

Autocatalytic Growth and Development and the South-North Convergence

Abstract:

This article engages with the issue of income convergence between North and South by using the autocatalytic hypothesis of growth and development. Two system models describe positive and negative feedback loops which govern economic flows between North and South. The analysis of endogenous and exogenous negative feedbacks points to the process that would slowly push the world economy towards vanishing growth rates and, eventually, halt its material growth. The present work rejects convergence in per capita GDP between North and South from the theoretical perspective. Such an outcome would stand against one of the fundamental properties of autocatalytic dynamics—centripetality— that has its causal roots in the competitive process and capitalist institutions. In that sense, the autocatalytic hypothesis provides a theoretical explanation for those empirical analyses that dismisses convergence.

Growth, income distribution and well-being in transition countries

We apply several well-being measures that combine average income with a measure of inequality to international and intertemporal comparisons of well-being in transition countries. Our well-being measures drastically change the impression of levels and changes in well-being compared to a traditional reliance on income measures. Due to low inequality and moderate income levels, socialist countries enjoyed relatively high levels of economic well-being. In the transition process, rising inequality and falling incomes have led to a dramatic absolute decline in well-being and a considerable drop in relative well-being vis-à-vis non-transition countries. We also find a close correlation between income losses and inequality increases. While the transition has been successful in expanding political and civil rights, our indicators suggest that most transition countries are still below the level of economic well-being of the late 1980s.

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.     

劳动力流动与收入收敛--一个改进的新古典增长模型及对中国的启示

文章将劳动力的流动性引进新古典增长模型,对于一个拥有一定资本密度的小型开放经济体而言,当它低于稳态时,劳动力的迁出会加快收入收敛的速度,但同时会对整体资本投资产生抑制作用;在收入水平相对较低时,这种抑制作用会超过其正面作用,从而劳动力流动会减缓收入收敛的速度;但从长期来看,随着劳动力流动性的提高,正面作用最终会占据主导地位,从而劳动力的无限自由流动会最终导致收入收敛于稳态.     

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’.     

中间投入品贸易对我国收入分配的影响:理论与实证

从理论上讲,中间投入品贸易的增长可以使发达国家和发展中国家技术型劳动的相对工资都有所提高,并且使各国对技术型劳动/非技术型劳动的相对需求都增加。本文从中国制造业的角度来研究中间投入品贸易对制造行业收入分配的影响。结果证明中间投入品贸易尤其是出口贸易对中国制造业收入分配的影响很大。     

收入分配:经济增长抑或“人的发展”——一个基于自由发展观的分析

以自由看待发展的观点将人的实质自由的扩展作为经济发展的内涵和目的,是人的发展思想下的一种系统理论。按照自由发展观,收入分配在经济发展中的重要作用主要体现在对自由的建构性作用和工具性作用的影响上。当前,我国收入分配出现的整体性、系统性失衡的严重问题对于人的发展的实现产生了极为深刻的影响,主要包括引发低收入群体自由的损害,劳动者可行能力降低,自由行使成本上升,发展方向偏离,中等收入群体发展受到制约等。因此,必须通过人的自由发展的收入分配观的树立和收入分配政策创新实现人的自由发展。     

Demographic Transition, Income Distribution, and Economic Growth

This article investigates the dynamic interactions among demographic transition, income distribution, and economic growth. Consistent with empirical evidence we show that fertility and income distribution follow an inverted U-shaped dynamics in the process of economic development. In the first stage fertility increases and income inequality widens, whereas in the second stage fertility declines, income becomes more equally distributed, human capital becomes more abundant, and growth of income per capita takes off. The model therefore generates the documented facts about epochs of demographic transition, relying neither on arguments based on near rationality nor on noneconomic objectives.
