Growth, income distribution, and fiscal policy volatility

The relationship between income distribution and economic growth has long been an important economic research subject. Despite substantial evidence on the negative impact on long-term growth of inequality in the literature, however, there is not much consensus on the specific channels through which inequality affects growth. The empirical validity of two most prominent political economy channels - redistributive fiscal spending and taxes, and sociopolitical instability - has recently been challenged. We advance a new political economy channel for the negative link between inequality and growth, a fiscal policy volatility channel, and present strong supporting econometric evidence in a large sample of countries over the period of 1960-2000. Our finding also sheds light on another commonly observed negative relation between macroeconomic volatility and growth. We carefully address the robustness of the results in terms of data, estimation methods, outlier problem, and endogeneity problem that often plague the standard OLS (ordinary least squares) regression.     

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.     

What drives inequality and poverty in the EU? Exploring the impact of macroeconomic and institutional factors

Employing panel data techniques, we investigate the macroeconomic and institutional determinants of inequality and poverty in the EU over the period 1994–2008. We pay particular attention to the effects of macroeconomic environment, social protection and labour market institutions. The empirical analysis shows that the social transfers in cash, and principally the transfers that do not include pensions, exert a prominent impact on inequality and poverty. Also significant is the effect of the GDP per capita. The impact of employment on inequality and poverty is not empirically sound. The same holds for the labour market institutions; an exception is the union density, which appears conducive to a less dispersed personal income distribution. Importantly, the results support the view that the social protection system acts as a catalyst in determining the effectiveness of social spending and the distributive role of economic growth and employment.     

Innovation,Diffusion and Cumulative Causation: Changes in the Spanish Growth Regime, 1960–2001

This article presents a model of macroeconomic growth that combines in a single formalization two complementary views on innovation and economic growth, the technology‐gap approach and the Kaldorian theory of cumulative causation. The model suggests that what matters for economic growth in the long run is the existence of a good match between the patterns of technological change, income distribution and demand growth. The model is estimated for the Spanish economy during the period 1960–2001, and the econometric results show that important changes have happened in its growth regime over time. Since the 1980s, innovation and diffusion of new technologies provide a greater stimulus to productivity growth, but the technology push on the supply‐side is not sustained by the prevailing patterns of income distribution and demand growth.     

Some institutional design for shareholder socialism

Abstract

In times of a declining labour share and an intense international tax competition, some form of market socialism may contribute to hold income inequality in check. However, the concept of market socialism involves three major pitfalls: cronyism, technological stagnation, and power concentration. These pitfalls could be avoided by an appropriate institutional design that includes the combination of public ownership with an extensive use of the stock market, an incentive-compatible mechanism for the takeover of private firms, and participatory democracy.     

The impact of macroeconomic factors on income inequality: Evidence from the BRICS

In this paper we investigate how the evolution of income growth, real interest rates, and inflation have driven income inequality across a variety of countries with particular focus on the BRICS economies (Brazil, Russia, India, China, and South Africa) during the period 2001 to 2015. Our work suggests that, when central banks of the BRICS economies use monetary policy for macroeconomic stabilization, they need to consider the impact monetary policy changes have on the distribution of income in their nations. Our estimates reveal that the unintended consequence of policies that induce economic growth and higher prices is higher income inequality. We find that the positive relationship between the three macroeconomic variables and income inequality for the BRICS economies is stronger during the post-2008 period.     

Vietnamese Economy at the Crossroads: New Doi Moi for Sustained Growth

Thanks to doi moi, Vietnam was successful in escaping the poverty trap and emerged as a lower middle‐income country in the late 2000s. From that time, however, the Vietnamese economy entered a new phase, which has been characterized by slow growth, weak international competitiveness, and macroeconomic instability. Apart from short‐term problems associated with the management of increasing foreign capital, the major factors accounting for the difficulties of Vietnam's current economic phase can be attributed to the Vietnamese style of the gradualist strategy of transition from a planned to a market economy, which protects state‐owned enterprises, and consequently to the failure to respond to the rapid rise of China. For further industrialization and sustained growth, Vietnam should embrace a new doi moi that follows the efficient type of gradualist strategy, with a special focus on new reforms of state‐owned enterprises and a policy that promotes the country' s dynamic comparative advantage.     

BANK COMPETITION,FINANCIAL DEVELOPMENT,AND INCOME INEQUALITY

Income inequality rises with financial development initially and then drops. We reach this conclusion by numerically solving a heterogeneous agent model parameterized to the Chinese economy. The model features a banking sector with Cournot competition, and the process of financial development in the model economy begins with the deregulation of the banking sector. Based on regressions with the fixed effects and the system generalized method of moments, the empirical analysis also suggests an inverted‐U relationship between income inequality and financial development using provincial data from China.

Financial deepening and income inequality: Is there any financial Kuznets curve in China? The political economy analysis

The interconnectedness of financial deepening and income inequality has been a highly controversial discussion which has not been concluded despite many empirical and theoretical studies up to date. One of the basic building blocks for many research designs is the reliance upon the Kuznets inverted U-shaped curve which postulates that in the first phase of economic growth income inequality increases, peaks and then decreases to a tolerable level in the later phase after a certain income level had been attained. The role of financial deepening in financing economic growth is an indispensable and necessary condition enabling us to easily draw an analogy between financial deepening and income inequality in a financial version of the Kuznets curve. In spite of 30 years of economic and financial reforms in China, which represents a fairly young history of economic growth and development, there are many indicators that Chinese experience significantly deviates from the presupposed inverted U-shaped curve trajectory and its final equalizing effect. This paper relies on financial deepening data measured by monetary aggregate M2/GDP and domestic banking credit/GDP ratios in its claim that they significantly correlate with rising income inequality. The author’s intention consists not in claiming that financial deepening per se causes income inequality, but provides a political economy analysis of the specific institutional and power configuration which leads to their positive relationship. This configuration is determined by the prevailing banking model, the hukou system, financial repression and the decentralized authoritarian system. On the other hand, the absence of inequality-narrowing institutitons further aggravate the problem. All the aforementioned factors are geared at avoiding mechanical and spurious claims that financial deepening increases or decreases income inequality across countries. A historical institutionalism approach to explain China’s path related to the Kuznets curve prediction shows the central validity of open and inclusive institutions in generating inequality-narrowing benefits of financial deepening.     

Germany in crisis: the unification challenge,macroeconomic policy shocks and traditions,and EMU

Conventional wisdom blames Germany's ongoing economic and fiscal crisis on the unification shock of the early 1990s and structural problems in labour markets. Challenging this view, this paper offers a fresh assessment that focuses on macroeconomic demand management. It is shown that Germany's fiscal crisis cannot be attributed to unification per se; it arose as a consequence of ill‐guided macroeconomic policies pursued in response to that event. Many structural problems that popped up along the way were mere symptoms of persistent macroeconomic mismanagement and protracted domestic demand stagnation. Arguably, systematically ill‐guided macroeconomic policies of this type are potent enough to wreck any real world economy, no matter how flexible it may be. Because Germany provided the blueprint for Europe's stability‐oriented macroeconomic policy regime, it comes as no surprise that a peculiar repeat of certain symptoms that started to arise in Germany a decade ago may now be observed across the euro area—protracted domestic demand weakness and inflation stickiness because of ‘tax‐push inflation’ in particular.     

Why the rich may favor poor protection of property rights

In unequal societies, the rich may benefit from shaping economic institutions in their favor. This paper analyzes the dynamics of institutional subversion by focusing on the public protection of property rights. If this institution functions imperfectly, agents have incentives to invest in private protection of property rights. The ability to maintain private protection systems makes the rich natural opponents of public property rights and precludes grass-roots demand to drive the development of the market-friendly institution. The economy becomes stuck in a bad equilibrium with low growth rates, high inequality of income, and wide-spread rent-seeking. The Russian oligarchs of 1990s, who controlled large stakes of newly privatized property, provide motivation for this paper. Journal of Comparative Economics 31 (4) (2003) 715–731.     

收入分配不平等与经济增长:回到库兹涅茨假说

本文运用一个政治经济模型,研究在财政支出同时具有生产性和消费性,同时进入总生产函数和代表性个人的效用函数时收入分配不平等对经济增长的影响。本文的分析表明:在经济均衡时,增长率与税率呈倒U型关系。随着税率增加,经济增长率先升后降;在政治均衡时,收入分配越不平等,实际资本税率就越高,因此收入分配不平等与经济增长间存在一定程度的库兹涅茨倒U型关系     

Patriarchy versus Islam: Gender and Religion in Economic Growth

ABSTRACT

This contribution evaluates whether affiliation with Islam is a theoretically and statistically robust proxy for patriarchal preferences when studying the relationship between gender inequality and economic growth. A cross-country endogenous growth analysis shows that direct measures of patriarchal institutions dominate a variety of religious affiliation variables and model specifications in explaining country growth rates, and that using religious affiliation, particularly Islam, as a control for culture produces misleading conclusions. This result is robust to the inclusion of measures of gender inequality in education and income, indicating that establishing and maintaining patriarchal institutions (a process this study calls “patriarchal rent-seeking”) exact economic growth costs over and above those measured by standard gender inequality variables. One of the key contributions of this study is to draw on unique institutional data from the Organisation for Economic Co-operation and Development's Gender, Institutions and Development (GID) database to better understand the gendered dynamics of growth.     

Inequality and Economic Growth: A Global View Based on Measures of Pay

This paper discusses two issues in the relationship betweeninequality and economic growth: the data and the econometrics.We first review the income inequality data set of Deiningerand Squire (D&S), which, we argue, fails to provide eitheradequate or accurate coverage, whether through time or acrosscountries. We then introduce our own measures of the inequalityof manufacturing pay, based on UNIDO's Industrial Statistics.These provide indicators of pay inequality that are more stable,more reliable and in our view also more comparable across countries,than the D&S data. Turning to the fabled "Kuznets" relationship between inequalityand economic development, we diagnose several common econometricproblems in the literature, including measurement error andomitted variable bias. By taking steps to account for theseproblems, and by introducing a more complete panel data setbased on pay inequalities, we seek more reliable inferencesconcerning the relationship between inequality, national incomeand economic growth. We find evidence that generally supportsKuznets' specification for industrializing countries: pay inequalitytends to decline as per capita income increases, though withsome tendency for the relationship to curve up for the richestcountries. After 1981 two findings emerge. First, per capitaGDP growth slowed dramatically in most countries, increasinginequality along the augmented Kuznets curve. Second, thereis a global and macroeconomic effect that produces rising inequalityin our data, independent of GDP or its changes. The timing ofthis effect suggests a link to the high real interest ratesand global debt crisis of the period beginning in 1982. (JELC23, D31, J31, O11)     

All About the Giants: Probing the Influences on World Growth and Income Inequality at the End of the 20th Century

This paper presents estimates of world output growth from 1970to 2000, the distribution of income among countries and personsfor the years 1980, 1990 and 2000, and world income povertyrates for the same years. It also presents the results of aseries of simulation exercises that attempt to isolate the effectof particular country and regional experiences on world outputgrowth and changes in global income inequality and poverty. The authors find that rapid growth in China (despite a downwardadjustment of official growth estimates) had a powerful impacton the growth of world output in both the 1980s and 1990s, butthat negative economic growth in Eastern Europe more than offsetthat effect in the 1990s. With respect to the distribution ofworld income between countries, the impressive growth performancesof the worlds most populous countries, China and India, ensureddecreasing levels of inequality during both the 1980s and 1990s.When the distribution of world income between persons is measured,the equalizing effect of China's rapid growth remains dominantthrough both the 1980s and 1990s, despite the contradictoryimpact of increasing domestic inequality. Only India's influenceremained substantial by comparison. Other identifiable eventsof the period, such as the economic contraction in Eastern Europeand continued economic decline in Africa, had little statisticalimpact. However, when the combined influence of China and India'sabove-average growth rates is removed, or their size effectdampened, the improving global distribution of (inter-countryand inter-personal) income suggested by all statistical measuresbecomes one of sharply worsening inequality. The impact of thesetwo countries is similarly critical with respect to global povertyreduction. (JEL F0, I3, O4)     

Status-seeking behavior,the evolution of income inequality,and growth

Using an overlapping generations model, this paper investigates the implications of status-seeking behavior, induced by preferences for relative income, for the evolution of income inequality. When average income rises, an individual’s marginal utility of their own income may increase (keeping up with the Joneses, or KUJ), or decrease (running away from the Joneses, or RAJ). It is shown that income inequality is shrinking over time in the KUJ economy, whereas it is expanding in the RAJ economy. We also explore the implications for long-run growth and inequality, in the existence of both KUJ and RAJ agents.

Can the link between functional and personal income distribution enhance the analysis of inequality?

The aim of this paper is to present a framework which links functional and personal income distribution. In the first part of the paper, Piketty’s book “Capital in the XXI Century” is briefly reviewed. Piketty’s framework is discussed arguing that it can only partially explain levels and changes within personal income distribution. Piketty links the returns from capital r to the rate of growth of national income g in a very innovative way comparing them within a macroeconomic framework. He claims that when returns on capital rise more quickly than the overall economy and taxes on capital remain low, a vicious circle of ever-growing dynastic wealth and growing concentration of wealth takes place. However, the rise in the inequality of personal income distribution cannot only be explained by the rise of capital incomes. An analysis of the generation of personal incomes, and consequently of inequality, requires a suitable framework that links incomes at the macroeconomic level (national accounts) and incomes at the level of the individual/household. It is possible to set up this framework starting from individual endowments and their link to the productive structure: that is to what can be called the “generating function of personal income.” This function transforms personal endowments into personal earnings, given the productive structure, the technologies, and the market rules that determine the functional distribution. Personal income distribution and its inequality are linked to the functional one through the shares of capital and labor owned by each individual. The framework introduced here seems to be a suitable tool to account for the fact that personal income distribution is inextricably tied up to different sources of inequality in the distribution of national income. Sources come from institutional and productive structures (matrix Y), but also from the distribution of endowments and of individual/household entitlements (matrix S). This approach, we argue, allows for the assessment and evaluation of the effects of “ambitious new policies,” aimed at reducing poverty and inequality ex-ante, as suggested by Atkinson in his last book.     

Men of Steel Meet the Market: Interpreting Firm Behavior in Russia’s Metallurgy Industry

In Capital in the Twenty-First Century, Thomas Piketty (2014) explains growing income inequality via the difference between the rate of return on capital and the growth rate of the economy: the “r > g” inequality. Even if it is true that r > g leads to increasing inequality, nearly every school of economic thought predicts that r will fall as the economy grows. Thus, for Capital (2014) to be a comprehensive theory of inequality, a more adequate theory of r is required. I term this the “Piketty Problem.” I offer a solution to this problem from an institutionalist perspective.     

Foreign bank ownership and income inequality: empirical evidence

ABSTRACT

Using country-level panel data over 1995–2013 on within-country income inequality and foreign bank presence, this paper establishes a positive relation between the two, running from higher foreign bank presence to income inequality. Given that foreign bank participation increased by 62% over the period 1995 to 2013, our baseline results imply a 5.8% increase in the Gini coefficient on average over this period, ceteris paribus. These results are robust to the inclusion of country and year fixed effects and to the use of restrictions on foreign bank entry in the host countries as an instrumental variable. We show that this positive effect is channelled through the lack of greenfield entry and the associated lower levels of competition.     

The Distribution of Human Capital and Economic Growth

This paper analyzes the interaction between the distributionof human capital, technological progress, and economic growth.It argues that the composition of human capital is an importantfactor in the determination of the pattern of economic development.The study demonstrates that the evolutionary pattern of the humancapital distribution, the income distribution, and economic growthare determined simultaneously by the interplay between a local home environment externality and a global technologicalexternality. In early stages of development the local home environmentexternality is the dominating factor and hence the distributionof income becomes polarized; whereas in mature stages of developmentthe global technological externality dominates and the distributionof income ultimately contracts. Polarization, in early stagesof development may be a necessary ingredient for future economicgrowth. An economy that prematurely implements a policy designedto enhance equality may be trapped at a low stage of development.An underdeveloped economy, which values equality as well as prosperity,may confront a trade-off between equality in the short-run followedby equality and stagnation in the long-run, and inequality inthe short-run followed by equality and prosperity in the longrun.
