Changing Sources of Household Income,Poverty, and Sectoral Inequality in Sri Lanka, 1990–2006

Comparing dynamic changes in household income and poverty among urban, rural, and estate sectors in Sri Lanka from 1990 to 2006, this study finds that a shift of household income away from farm to nonfarm sources is accompanied by a significant improvement in household income and reduction in poverty, particularly in the rural sector. Major contributing factors are the rise in returns to labor, in general, and educated labor, in particular, due to the development of the nonfarm labor market. Persistently low income among estate households can be explained primarily by the limited availability of nonfarm employment opportunities and the low education levels of working members.     

Will China's WTO accession worsen farm household incomes?

Many fear China's accession to the World Trade Organization (WTO) will impoverish its farmers via greater import competition in its agricultural markets. We explore that possibility bearing in mind that, even if producer prices of some (land-intensive) farm products fall, prices of other (labor-intensive) farm and nonfarm products could rise. New estimates, from the global, economy-wide numerical simulation model known as Global Trade Analysis Project (GTAP), of the likely changes in agricultural and other product prices as a result of WTO accession, are drawn on to examine empirically the real income implications of China's WTO accession. The results suggest farm–nonfarm income inequality may well rise within China but rural–urban income inequality need not. The article concludes with some policy suggestions for alleviating any pockets of farm household poverty that may emerge as a result of WTO accession.     

Community poverty and inequality in western China: A tale of three villages in Guizhou Province

Using a census survey of households in Guizhou Province, this paper examines the patterns of village poverty and inequality and their major correlates. The results show that poverty incidences vary greatly among villages and inequality is relatively high within villages in these impoverished areas. Although agriculture is still the major source of livelihood in this inland western region, income from local nonfarm jobs and remittance is more unevenly distributed and accounts for the largest share of overall income inequality. Surprisingly, blood donation is another major source of cash income. On the expenditure side, health care was found to be one of the most important sources of inequality. The paper also found that the distribution of assets, particularly land holdings, contributes to overall income inequality.     

Rural Nonfarm Incomes in Nicaragua

This paper examines nonfarm incomes of rural Nicaraguan households using a nationwide survey (LSMS) from 1998. The key findings are as follows. (a) Rural nonfarm income (RNFI) constitutes 41% of rural household incomes. (b) RNFI is much more important than farm wage-labor income. (c) RNFI tends to be relatively concentrated geographically and socioeconomically, toward the rural areas of the Managua zone and the Rest-of-Pacific zone, which are denser in infrastructure and population, and toward the upper income quartile of rural households. This concentration implies high entry barriers and capital requirements for rural nonfarm activity that the poor are simply not equipped to overcome. Equipping the rural poor through training and acquisition of diverse forms of capital to have a chance at the higher return nonfarm jobs would be a major step toward helping them to share the benefits of the rural nonfarm economy. (d) Self-employment (small enterprise) income in manufactures is very minor, probably due to the ease of obtaining manufactured goods from urban industries and imports. Wage employment constitutes the bulk of RNFI (despite it receiving little attention in development programs and debate). (e) Three-quarters of RNFI is in the service sector, and only one-quarter is from manufactures; that can be contrasted with the emphasis on small manufactures enterprises in rural development programs and research. (f) Education, road access, as well as access to electricity and water were found to be important to nonfarm incomes.     

Tax policy implications for a two‐engine growing economy

In an endogenous growth model with two engines of R&D and capital, we investigate the environment of “inclusive growth” for tax reallocations (tax increases or tax credits) to gain broader benefits in terms of promoting the overall GDP growth without an increase in income inequality. Our results show that a tax increase in the capital‐good sector can result in inclusive growth, boosting overall growth and reducing income inequality, provided that the status quo tax rate is not too high. Surprisingly, tax credits are not able to achieve such inclusive growth. While the GDP growth rises, a tax credit in the R&D sector not only increases income inequality but also decreases the aggregate employment, if the labor mobility cost between the final‐good and R&D/capital‐good sectors is relatively low. This provides a caution to policymakers given the fact that research tax credits have served as a common incentive to strengthen the R&D environment.     

Long‐term trends in economic inequality: lessons from colonial Botswana, 1921–74

This article contributes to the growing literature on colonial legacies influencing long‐term development. It focuses on Botswana, a case where the post‐independence diamond‐led economy has been considered an economic success story, despite its high levels of inequality. Here it is argued that this pathway of rapid resource‐driven growth combined with increasing socio‐economic inequality had already started during the time of the colonial cattle economy, and that this older case is equally relevant for understanding long‐term growth‐inequality trends in Botswana and other natural‐resource‐dependent economies. Six social tables, covering the period 1921 to 1974, are constructed using colonial archives, government statistics, and anthropological records. Based on the social tables, income inequality is estimated in the colonial and early post‐independence eras, capturing both the formal and informal sectors of the economy. The article demonstrates how the creation of a cattle export sector in the 1930s brought new opportunities to access export incomes, and how this led to a polarization in cattle holdings and increasing income inequalities. Further, with the expansion of colonial administration, government wages forged ahead, increasing income inequality and causing a growing income divide between public and private formal employment.     

Finance and Income Inequality: What Do the Data Tell Us?

Although there are distinct conjectures about the relationship between finance and income inequality, little empirical research compares their explanatory power. We examine the relationship between finance and income inequality for 83 countries between 1960 and 1995. Because financial development might be endogenous, we use instruments from the literature on law, finance, and growth to control for this. Our results suggest that, in the long run, inequality is less when financial development is greater, consistent with Galor and Zeira (1993) and Banerjee and Newman (1993). Although the results also suggest that inequality might increase as financial sector development increases at very low levels of financial sector development, as suggested by Greenwood and Jovanovic (1990), this result is not robust. We reject the hypothesis that financial development benefits only the rich. Our results thus suggest that in addition to improving growth, financial development also reduces inequality.     

Household appliance ownership and income inequality: Evidence from micro data in China

As the residential sector is becoming increasingly important in the total energy consumption and appliance ownership is a significant but under-examined driver, this study investigates the relationship between income inequality and appliance ownership using panel data from the China Health and Nutrition Survey (CHNS). We find that income inequality has negative impacts on appliance penetration rate across specifications, except for the initial development stage. On average, households start adopting air conditioners at a threshold of over 60,000 (2011 RMB) based on annual income, much higher than TV, fridge and washer (8500–9000 RMB). The empirical results validate the S-shape curve of appliance established in the literature. To understand the magnitude of the impact and policy implications, we further simulate the impact of poverty alleviation and the penetration paths under inclusive versus exclusive income growth. Our results demonstrate that current poverty line is too low to achieve appliance adoption – a signal for modern life-styles. In addition, a more inclusive growth path could lead to much higher penetration for regions that have relatively low growth rate.     

去工业化对收入不平等的影响:机制分析与实证检验

基于126个国家1991-2017年的面板数据,考察了去工业化对收入不平等的影响。研究发现,去工业化会显著加剧收入不平等程度,这在发展中经济体尤为显著。从传导机制看,去工业化既可以通过劳动力就业转移直接影响收入不平等,也可通过非熟练劳动力就业和服务业部门就业分化间接影响收入不平等。一方面,去工业化导致非熟练劳动力受到更大冲击,致使该部分劳动力失业,加剧收入不平等;另一方面,去工业化导致非熟练劳动力的就业从工业的高薪部门转移至服务业的低薪部门,最终影响收入不平等。进一步研究发现,在可能存在"过早去工业化"的国家去工业化对收入不平等的作用更加明显。因此发展中经济体要着重预防由于去工业化可能带来的收入不平等程度恶化。     

Rural Nonfarm Employment and Incomes in Latin America: Overview and Policy Implications

Rural nonfarm employment (RNFE) and incomes (RNFI) are crucial to Latin American rural households. The 11 rural household income studies in this volume, reviewed in this paper, use 1990s data and show that RNFI averages 40% of rural incomes. RNFI and RNFE have grown quickly over the past three decades. The review of evidence provided some surprising departures from traditional images of nonfarm activities of Latin American rural households. In terms of shares of rural incomes: (1) nonfarm wage incomes exceed self-employment incomes; (2) RNFI far exceeds farm wage incomes; (3) local RNFI far exceeds migration incomes; (4) Service-sector RNFI far exceeds manufactures RNFI. These findings suggest the need for more development program attention to wage employment in the service sector, versus the traditional focus on small enterprise manufactures. Moreover, poor households and zones tend to have higher shares in their incomes but lower absolute levels of RNFI as compared to richer households and zones. The RNFE of the poor tend to be the low-paid nonfarm equivalent of semi-subsistence farming. Raising the capacity of the poor to participate in the better-paid types of RNFE is crucial — via employment skills training, education, infrastructure, credit. Finally, RNFE has grown fastest and been most poverty-alleviating where there are dynamic growth motors, in particular in the agricultural sector, but also in tourism, links to urban areas, mining and forestry. This means that developing RNF jobs cannot be done at the expense of programs promoting agricultural development.     

Nonfarm Employment and Poverty Alleviation of Rural Farm Households in Honduras

This paper analyzes the role of nonfarm income of rural farm households in Honduras. It uses the national income and expenditure survey from 1993 to 1994. Income from nonfarm wage and self-employment represents 16–25% of farm household income and is especially important for middle and higher income strata. Nonfarm wage labor is geographically concentrated in small rural towns and in the industrial free zones located in the Northern region, while self-employment is particularly developed in the Southern region. Access to nonfarm wage employment is confined to educated individuals that belong to large households, while female members of wealthier households are mainly involved in self-employment. Food security is strongly enhanced through the engagement in nonfarm activities. Moreover, nonfarm income enables farmers to purchase external inputs for improving yields and labor productivity. Suitable policies to enhance nonfarm employment include education, training, and technical assistance to reduce labor intensity in agricultural production, as well as public investment and credit services to improve access to nonfarm activities.     

The growth,poverty and inequality nexus in South Africa: Cointegration and causality analysis

This study empirically established the long-run relationship and causality effects that exist between growth, poverty and inequality. The analysis was carried out on a panel of nine South African provinces from 1995 to 2012. To capture poverty and inequality in a broader context, two measures of poverty (income and non-income) and three measures of inequality (income, education and land) were adopted for the study. The results confirm that there is a long-run relationship between growth, poverty and inequality. Notable results from the causality tests suggest that growth does not promote equal distribution of income in society but as income distribution begins to equalise, economic growth rises. This is regarded as growth–inequality disconnect. The unidirectional causality, which runs from income poverty to income inequality, suggests that a rising level of income poverty will lead to falling income inequality in the society; likewise, income inequality increases as non-income poverty declines.     

Financial openness,financial sector development,and income inequality: With an extensive set of pull and push factors

This paper investigates the impact of financial openness on financial sector development and income inequality. We use the de jure and de facto measures of financial openness across 78 countries from 1980 to 2019. By employing a system generalized method of moments (GMM) with 5-year averaged data and a novel push and pull modeling framework, we obtain three key results. First, the de jure measure of financial openness exacerbates income inequality and is sensitive to banking crises and conflict intensity. Second, the de facto measure spurs stock value traded in emerging market economies (EMEs) and declines domestic credit in Africa. Third, the interaction between de facto measures with schooling and governance factors affects financial sector development and income inequality. We highlighted that the mere usage of the de jure measure and their interaction is incorrect. The key implication is that valuable information about the real impact of openness can be obtained from the de facto measures and their interaction with favorable macroeconomic fundamentals, governance factors, and adverse nonpolicy factors.     

The Determinants of Nonfarm Income Diversification in Rural Peru

This paper shows that in Peruvian rural areas, there has been substantial growth over the past decade in household employment outside of own-farming. At present 51% of the net income of rural households comes from these off-farm activities, and thus they certainly cannot be considered as “marginal.” The reasons households diversify their incomes are several. Access to public assets such as roads and private assets such as education and credit is an important factor in diversification. Increasing access to these assets will help rural households to increase their self-employment as well as wage employment in the nonfarm sector.     

Income Inequality,Taxation, and Growth

Much recent theoretical and empirical research has focused on the relationship between income distribution and economic growth. The fiscal policy approach argues that inequality is linked to pressure for redistributionary taxation, leading to low capital investment and, therefore, growth. Empirical analyses are consonant with this view in that the long-run relationship between inequality and growth is negative. However, several empirical inconsistencies with the fiscal policy approach do emerge: (a) there exists a short-run, positive relationship between income inequality and growth and (b) the relationship between inequality and taxation is mixed, at best. This paper presents a simple theoretical model that reconciles the intuitively appealing fiscal policy approach with the empirical findings.     

Carbon emissions and income inequality

We find that the distribution of income matters to aggregatecarbon dioxide emissions and hence global warming. Higher inequality,both between and within countries is associated with lower carbonemissions at given average incomes. We also confirm that economicgrowth generally comes with higher emissions. Thus our resultssuggest that trade-offs exist between climate control (on theone hand) and both social equity and economic growth (on theother). However, economic growth improves the trade off withequity, and lower inequality improves the trade off with growth.By combining growth with equity, more pro-poor growth processesyield better longer-term trajectories of carbon emissions.     

收入分布、厂商定价与耐用品的消费扩张

本文考察了收入差距对耐用消费品消费的影响。我们从厂商的定价理论出发。说明了收入差距对耐用消费品消费呈现出倒U型的影响：随着收入差距扩大，耐用消费品的消费量增加，但是，收入差距继续扩大则会减少耐用消费品的消费。这说明，适当的收入差距有利于社会消费水平提高和经济的发展，过大和过小的收入差距都无助于经济的起飞。我们最后运用城镇居民和农村居民彩电、洗衣机和冰箱的拥有量对该理论进行了实证检验，实证检验结果基本上支持了我们的理论分析。     

The Impact of Personal Income Tax Structure on Income Inequality for Belgium,Bulgaria, Germany,Lithuania, and Poland: A Comparison of Flat and Graduated Income Tax Structures

The level of income inequality in a country is usually a contentious and politically divisive issue. How the tax structure affects this inequality is of crucial concern to policymakers. In this paper, we examine the income tax experiences of five European Union countries: Belgium, Bulgaria, Germany, Lithuania, and Poland. This paper focuses on the comparison between flat and graduated personal income tax rate structures. Various methods were used to measure the progressivity of income taxes across these countries such as the average tax rate, cumulative shares of income, and the Gini and other indices. The findings show that the graduated rate income tax structure of Germany and Belgium are the most effective at reducing inequality. On the other hand, Lithuania’s proportional income tax structure is much more effective at reducing income inequality when compared to the graduated rate structure of Poland. Also, an appropriately-sized income tax threshold can transform a flat structure to a redistributive one that compares favorably with some graduated rate structures. In the case of Bulgaria, introducing an income tax threshold that is roughly the size of average income would reduce inequality by about 4 %.

     

Whatever happened to the Kuznets curve? Is it really upside down?

Kuznets (1955) embarked on a research program whose goal was to find the determinants of the long run levels and trends in income inequality and the relationship between income inequality and economic growth. Recently a small body of theoretical work has developed which tries to obtain the inverted U hypothesis as an equilibrium outcome in dynamic general equilibrium model. One of the types of general equilibrium models which can deliver a Kuznets curve is a model which allows for persistent migration out of one sector, e.g. agriculture, into another—e.g., manufacturing. Most industrialized countries have not only experienced shifts from agriculture to manufacturing, but also into services, especially associated with information technologies. This is responsible for the rise in inequality. If such a model of the arrival of new opportunities is correct, we would not expect to find a Kuznets curve, right side up or up-side down. Here we review the empirical evidence regarding the Kuzuets curve.     

Small Enterprise Growth and the Rural Investment Climate: Evidence from Tanzania*

Abstract: This paper analyzes characteristics of nonfarm enterprises, their employment growth patterns, and constraints in doing business in rural Tanzania. Using unique survey data, we describe a low‐return sector struggling to compete in a challenging business environment. However, about one‐third of rural enterprises are growing fast. Most enterprises engage in agricultural trade. Due to a rapidly growing agricultural sector in recent years, limiting demand‐side constraints, rural enterprise constraints in Tanzania mainly operate from the supply‐side, suggesting that in particular access to finance, road infrastructure and rural cell phone communication is associated with employment growth. A major finding is that subjective and objective measurements of business constraints are broadly comparable. We discuss a number of factors that would help to unleash the full potential of private sector‐led growth in rural areas. Marginal improvements of the rural investment climate matter for growth.
