Inequality Stagnation in Latin America in the Aftermath of the Global Financial Crisis

Between 2003 and 2010, Latin America experienced a solid record of economic growth, coupled with a notable reduction in income inequality. The regional Gini coefficient fell from 0.556 to 0.521 and declined in all 15 out of 17 countries in which frequent data are available. However, previous studies have warned about problems in the sustainability of the decline in income inequality and this study presents evidence of stagnation on this front between 2010 and 2013. The results are robust to various measures of income inequality, but differ across the region. While largely attributable to the recovery from the global financial crisis in Mexico and some countries in Central America, the results are also supported by the demonstrated slowdown in inequality reduction in other countries, including Brazil, Ecuador and Bolivia.     

Regional output growth and the impact of macroeconomic shocks in Mexico

This paper presents an empirical analysis of the relationship between national and regional output growth in Mexico, and the impact of domestic and international shocks on national, regional and state output movements. Our results suggest that there are similarities, but also significant differences, in real output dynamics across the regions and states of Mexico and that it would be wrong to regard the Mexican economy as a homogeneous entity. The results show that real output growth in Mexico and the United States are linked, but there is no common output trend for the two countries. At the regional level, it appears that North and Central Mexico share similar features, but the path of output growth is more distinctive in South Mexico. Overall, our results suggest that assessments of macroeconomic performance, and related discussions of policy, should pay greater attention to the potential diversity in regional performance.     

Product and process innovation and total factor productivity: Evidence for manufacturing in four Latin American countries

The literature on firm productivity recognizes the important role played by firm innovation activities on firm productivity in developed countries. However, the literature for developing and emerging economies is scarce and far from conclusive. The aim of this paper is to study the innovation–productivity link (distinguishing between process and product innovations) for manufacturing at the firm level for four Latin American countries (two classified as upper‐middle income countries by the World Bank—Argentina and Mexico—and two as lower‐middle income—Colombia and Peru). We aim testing whether the level of development is a mediating factor in the innovation–productivity link. The data used have been drawn from the World Bank panel enterprise surveys, for 2006 and 2010. First, we estimate total factor productivity (TFP) and, second, we use the estimated TFP as a regressor or as dependent variable, in two models for testing self‐selection of the most productive firms into innovation or the existence of returns to innovation in terms of productivity. Our results confirm the mediating role of the level of development in the innovation–productivity link: both the self‐selection and the returns‐to‐innovation hypotheses work only for the upper‐middle income countries.     

INCOME INEQUALITY IN URBAN COLOMBIA: A DECOMPOSITION ANALYSIS

The persistence of poverty and income inequality in less developed countries (LDCs) is a source of serious concern to development economists. To understand the structure of inequality, several researchers using a variety of methodologies have measured the importance of various contributory factors to overall income variability. The available literature—which now includes studies of Brazil, Mexico, Iran, the Philippines, Taiwan, Thailand, Pakistan, and Colombia-has been reviewed elsewhere (Fields, forthcoming). This paper presents additional evidence for urban Colombia, in the process raising some important methodological issues which bear on the design of future research studies.
The data set used in this paper is described in Section I. The decomposition of Colombian inequality by functional income source is presented in Section 11 for micro data. Section I11 examines the robustness of source decomposition procedures to data aggregation. Section IV presents inequality decompositions by city, and Section V by other income-determining characteristics. Conclusions appear in Section VI.     

Pareto–lognormal distributions: Inequality,poverty, and estimation from grouped income data

The (double) Pareto–lognormal is an emerging parametric distribution for income that has a sound underlying generating process, good theoretical properties, and some limited favorable evidence of its fit to data. We extend existing results for this distribution in 3 directions. (1) We derive closed form formula for its moment distribution functions, and for various inequality and poverty measures. (2) We show how it can be estimated from grouped data using GMM. (3) Using grouped data from ten countries, we compare its performance with that of another leading 4-parameter income distribution, the generalized beta-2 distribution. The results confirm that, when using grouped data, both distributions provide a good fit, with the double Pareto–lognormal distribution outperforming the beta distribution in 4 out of 10 cases.     

Global and regional inequality in the distribution of income: Estimation with limited and incomplete data

The paper examines the nature and extent of global and regional inequality using the most recent country level data on inequality drawn from World Bank studies, and real per capita income from the Penn World Tables, for the period 1980–1990. The methodology employed in the paper is based on a mixture of parametric and non-parametric approaches to inequality measurement. It is designed to handle the limited and incomplete nature of income distribution data from different countries. Empirical results show a very high degree of global inequality, but with some evidence of catch-up and convergence between regions.     

INCOME POVERTY AND MULTIDIMENSIONAL DEPRIVATION: LESSONS FROM CROSS‐REGIONAL ANALYSIS

The study of multidimensional deprivation has become one of the most relevant lines of research in the analysis of low‐income households. The search for significant relationships between multidimensional deprivation and income poverty has been a central issue and most empirical studies have found a very weak link. This paper aims at examining the possibility of an aggregation bias in national‐level studies, which could conceal disparities between regions. As regional differences and decentralization processes stand out in Spain as compared to other OECD countries, we focus the analysis on this country. Latent class models are used to define deprivation indices using the Spanish EU‐SILC. The results seem to show that the absence of significant relationships between both phenomena still holds at a regional level. The decomposition methods used in the paper show that it might be due to some regional singularities in some determining factors of income and multidimensional poverty.     

Bilateral and regional trade elasticities of the EU

The traditional way of assessing the impact of currency depreciation and income on the trade balance has been to estimate the elasticity of trade volume to relative prices and income. The previous studies examine the problems associated with using aggregate data. The recent studies rely on bilateral data, yet another problem is that data for export and import prices are not available. Thus, this study proposes an alternative way of assessing the impact of currency depreciation by using the real exchange rate and the impact of income on bilateral trade. The models are applied between the EU and its major trading partners. Furthermore, the analysis includes the six major trading regions along side the eight major trading countries for 1980–2007, on the quarterly basis. This article uses the autoregressive distributive lag (ARDL) approach advocated by Pesaran and Pesaran (1997). Our results indicate a higher importance of income compared to the real exchange rate in defined bilateral export and import demand functions. In addition, the applied CUSUM and CUSUMSQ stability tests confirm the stability of estimated coefficients in most cases.     

Housing and Income Inequality in Europe: Distributional Effects of Non-Cash Income From Imputed Rents

This article uses survey data to estimate non-cash income from imputed rents, using a consistent methodology for all countries to assemble comparable statistics that allow for a valid inter-country comparison. We can confirm a significant impact of non-cash income and find an inequality-decreasing effect for the unconditional income distribution which highly correlates with the proportion of owner-occupiers in the respective countries. However, aggregated inequality measures are not suited to analyze the increase in the conditional income inequality between owner-occupiers and renters, who do not obtain income from imputed rents by definition. Therefore, we apply a reweighting decomposition that controls for the heterogeneous housing characteristics among European countries and allows us to decompose the distributional changes into a part that is explained by the proportion of tenure types and household size and a remaining part that reflects the relative dispersion of imputed rents along the income distribution.     

Income mobility and risk during the business cycle: Comparing adjustments in labour markets in two Latin-American countries

This paper uses panel data from Argentina and Mexico and a new measure of mobility ‐ the Gini index of mobility ‐ to answer three questions. First, is there a trend towards rising labour income mobility over time in these two countries? Second, is there a relationship between income mobility and growth common to both countries, or does that relationship depend on the institutional features of each country’s labour markets? Third, do we observe more labour income mobility within some groups such as the young and the less educated than within other groups? JEL classification: D31, E32, J63.     

INCOME DISTRIBUTION AND ECONOMIC GROWTH IN PUERTO RICO,ARGENTINA, AND MEXICO*

Has economic growth in developing countries led to increasing inequality in the size distribution of income? Following a brief review of the advantages and deficiencies of several traditional measures of income distribution, the author examines the evidence from Puerto Rico, Argentina, and Mexico in recent years. The findings suggest that the income shares received by the lower half and by the top 5 per cent of families in Puerto Rico and Mexico have declined from 1950 to 1963, while the income shares received by the bottom nine deciles of families in Argentina have also fallen during the same period. The rising Gini ratio and standard deviation of the logs of income, both indicating greater inequality, contrast with a declining coefficient of variation for all three countries. More detailed sectoral distributions for each year reveal greater equality within agriculture than non-agriculture for Puerto Rico and Mexico, while Argentina and the United States demonstrate less equality within agriculture. The trends in the countrywide distributions are consistent with the observation of the increasing differential between sectors, the increasing weight of the more unequal sector, and the increasing level of inequality within both sectors. These trends, however, are qualified by the particular set of measures which are applied to the data. Finally, the author speculates on possible explainations for these trends in terms of changes in the crop and industry mix.     

Structural current accounts in the European Union countries: cross-sectional exploration

This paper investigates structural determinants of the current account balance and assesses whether the current accounts in the European Union countries were consistent with the calculated structural current accounts between 1995 and 2017. We estimate current account regressions using cross-sectional data for 94 countries in 2008–2016 and confirm the main findings with panel data estimates. We document that the current account depends on the real exchange rate in a nonlinear way. The real exchange rate affects the current account at low income levels, but it ceases to be important at high income levels. Based on structural current account estimates for the European Union countries, we document that after the 2008 crisis current accounts adjusted towards structural current accounts in deficit countries, but persisted above structural current accounts in surplus countries.     

Growth,inequality, and poverty reduction in developing countries: Recent global evidence

The study presents comparative global evidence on the transformation of economic growth to poverty reduction in developing countries, with emphasis on the role of income inequality. The focus is on the period since the early-mid-1990s when growth in these countries as a group has been relatively strong, surpassing that of the advanced economies. Both regional and country-specific data are analyzed for the $1.25 and $2.50-level poverty headcount ratios using World Bank Povcalnet data. The study finds that on average income growth has been the major driving force behind both the declines and increases in poverty. The study, however, documents substantial regional and country differences that are masked by this ‘average’ dominant-growth story. While in the majority of countries, growth was the major factor behind falling or increasing poverty, inequality, nevertheless, played the crucial role in poverty behavior in a large number of countries. And, even in those countries where growth has been the main driver of poverty-reduction, further progress could have occurred under relatively favorable income distribution. For more efficient policymaking, therefore, idiosyncratic attributes of countries should be emphasized. In general, high initial levels of inequality limit the effectiveness of growth in reducing poverty while growing inequality increases poverty directly for a given level of growth. It would seem judicious, therefore, to accord special attention to reducing inequality in certain countries where income distribution is especially unfavorable. Unfortunately, the present study also points to the limited effects of growth and inequality-reducing policies in low-income countries.     

City CPI Convergence in Mexico

This paper tests the purchasing power parity hypothesis within a single developing country currency area: Mexico. This work stems from research in comparing price movements across countries and a growing literature on price dynamics within a single currency area. The author uses city Consumer Price Index data for 34 cities in Mexico over the period 1982–2000. He followed the standard procedure of testing for I(1) processes in relative city prices, or city real exchange rates, using univariate and panel unit root tests. The main results of the paper are: First, Mexican city relative prices are stationary—the data rejects the hypothesis that city real exchange rates contain a random walk, but only using panel unit root techniques. Finally, regional demand and supply homogeneity implies stronger evidence for price parity within regions, while there is considerable evidence of regional price convergence, regional homogeneity does not guarantee faster convergence.     

Population and economic growth: a cointegration analysis of lesser developed countries

The authors examine the temporal relationship between population growth and economic growth in Nepal, India, Ghana, Sri Lanka, Bolivia, Philippines, Guatemala, Syria, Peru, Thailand, Chile, Argentina, and Mexico, conducting Granger-causality tests in the context of error correction models when cointegration is present. Their goal is to provide additional time series econometric evidence on the short-run and long-run time series behavior of population growth and the growth of real per capita gross domestic product for a sample of low to middle income developing countries. Cointegration was found in only 3 of the 13 countries examined. Even though 10 countries in this study exhibited no properties of cointegration, researchers conducting time series studies of the relationship between population growth and economic growth using differenced data should nonetheless evaluate the possible long-term relationship. Capturing the short- and long-run behaviors of the respective time series may give the researcher a more robust test of Granger-causality.     

The urban–rural divide

A vast literature has related perceptions of income inequality to individuals' income: the higher the level of income, the less inequality is perceived. Here, examining the perceptions of income and social inequality, we argue that rural or urban residence affects both inequality perceptions and the impact of income on these perceptions. We test the theory using survey data from 12 Central and Eastern European countries and we find that income negatively affects inequality perceptions but only in urban areas. These findings confirm the importance of accounting for urbanity to understand what drives individuals' perceptions of inequality.     

Foreign direct investment and China's regional income inequality

China's widening regional income inequality coupled with its pronounced regional disparity in foreign direct investment stock since 1990 has claimed the attention of many scholars. While some researchers confirm regional disparity in China's foreign direct investment, others attribute the widening regional income inequality to this regional disparity. This paper thus assesses the impacts of China's stock of foreign direct investment on its regional income inequality using simultaneous equation model and the Shapley value regression-based decomposition approach. Our results suggest that China's stock of foreign direct investment has accounted for merely 2% of its regional income inequality. Furthermore, the contribution ratio of per capita foreign direct investment stock to China's regional income inequality has relatively been on a steady decline since 2002. The decomposition results also reveal that provincial per capita physical assets account for over 50% of the nation's income inequality and 65% of the increases in income inequality since 1990. The other two important determinants of regional income inequality are province location and educational level. However, educational level is found to have a decreasing effect on regional income inequality.     

Tests of Income Pooling in Household Decisions

Using the Progresa data from Mexico, we investigate intrahousehold decision making using a variety of outcomes. We exploit both the experimental nature and the (short) panel dimension of the data to measure the impact of exogenous changes in the intrahousehold distribution of resources on household decisions. We test for global pooling of resources within households, which would correspond to the unitary model of household decision making. We also exploit a set of questions about power and the decision making process in the household to investigate aspects of strategic interactions between household members. Our findings confirm previous rejections of income pooling. We also cannot reject that the wife's relative income share is a significant determinant of the wife's decision making power in the household, with a higher share of income associated with more decision making power.

Measuring lnequality in the Middle East 1990–2016: The World’s Most Unequal Region?

In this paper we combine household surveys, national accounts, income tax data and wealth data in order to estimate income concentration in the Middle East for the period 1990–2016. According to our benchmark series, the Middle East appears to be the most unequal region in the world, with a top decile income share as large as 64 percent, compared to 37 percent in Western Europe, 47 percent in the US and 55 percent in Brazil (see Alvaredo et al. 2018). This is due both to enormous inequality between countries (particularly between oil‐rich and population‐rich countries) and to large inequality within countries (which we probably under‐estimate, given the limited access to proper fiscal data). We stress the importance of increasing transparency on income and wealth in the Middle East, as well as the need to develop mechanisms of regional redistribution and investment.     

ICT Use in the Developing World: An Analysis of Differences in Computer and Internet Penetration

Using panel data for 161 countries, we explore the determinants of cross-country disparities in personal computer and Internet penetration. We find evidence indicating that income, human capital, the youth dependency ratio, telephone density, legal quality, and banking sector development are associated with technology penetration rates. Estimates from Blinder–Oaxaca decompositions comparing rates in the developed-country total to developing countries (Total, Brazil, China, Indonesia, India, Mexico, and Nigeria) reveal that the main factors responsible for low rates of technology penetration rates in developing countries are disparities in income, telephone density, legal quality, and human capital. In terms of dynamics, our results indicate fairly rapid reversion to long-run equilibrium for Internet use, and somewhat slower reversion for computer use.
