Managing Food Price Instability in Asia: A Macro Food Security Perspective*

The present paper describes the benefits and costs, in qualitative terms, of managing food price instability in Asia in the context of promoting economic growth and poverty reduction to improve food security. The experience of Asian governments in actual practice with price stabilization is discussed in the context of managing an efficient transition to market‐mediated food security. Recent experience in Indonesia, where a sharp increase in rice prices (caused by a ban on rice imports) pushed 4 million people into poverty, provides continued motivation for the analytical story in this paper.     

Income and Price Elasticities of China＇s Exports

The appearance of new product varieties and improvements in the quality of goods have both played key roles in the rapid growth of China's exports. However, these two important elements have not been formally integrated into the demand equations for China's exports. As we demonstrate in this paper, income elasticity will be underestimated if new varieties of goods and quality improvements are omitted in price index and quantity index calculations, which are necessary for estimating the export demand function. Moreover, the faster new product varieties enter export markets, the greater the underestimation will be. In this paper, we develop an export demand equation that takes into account new product varieties and improvements in quality, and then calculate the demand function for China's exports using the data from 1992 to 2006. According to our estimation, the short‐term income elasticity of demand for China's exports is approximately 2.34, and the short‐term price elasticity is approximately –0.65. Our estimation predicts an increase in China's export value in the case of an RMB appreciation or export rebate rates reduction in the short term, due to the low price elasticity of China's exports, whose absolute value is less than 1. Our findings are novel and could have significant policy implications.     

Do International Remittances Affect Poverty in Africa?*

Abstract: International remittances flowing into developing countries are attracting increasing attention because of their rising volume and their impact on recipient countries. This paper uses a panel data set on poverty and international remittances for African countries to examine the impact of international remittances on poverty reduction in 33 African countries over the period 1990–2005. We find that international remittances—defined as the share of remittances in country GDP—reduce the level, depth, and severity of poverty in Africa. But the size of the poverty reduction depends on how poverty is being measured. After instrumenting for the possible endogeneity of international remittances, we find that a 10 percent increase in official international remittances as a share of GDP leads to a 2.9 percent decline in the poverty headcount or the share of people living in poverty. Also, the more sensitive poverty measures—the poverty gap (poverty depth) and squared poverty gap (poverty severity)—suggest that international remittances will have a similar impact on poverty reduction. The point estimates for the poverty gap and squared poverty gap suggest that a 10 percent increase in the share of international remittances will lead to a 2.9 percent and 2.8 percent decline, respectively, in the depth and severity of poverty in African countries. Regardless of the measure of poverty used as the dependent variable, income inequality (Gini index) has a positive and significant coefficient, indicating that greater inequality is associated with higher poverty in African countries, much in conformity with the literature. Similar results were obtained for trade openness. In the same vein, per capita income has a negative and significant effect on each measure of poverty used in the study. Our results also show that inflation rates positively and significantly affect poverty incidence, depth and severity in Africa. In all three poverty measures, the dummy variable for sub‐Saharan Africa is strongly positive, and strongly negative for North Africa. The policy implications of these results are discussed.     

Towards a better measure of income inequality in Indonesia

Indonesia has experienced significant economic growth in recent years (on average, 5% in 2000–08), but many people are still living in poverty. Income inequality, as measured by the official Gini coefficient, has also increased. This paper evaluates household income and income inequality in Indonesia, assessing both market and non-market income to reach a more accurate measure of how actual income affects living standards. We find that if household income considers non-market income, income distribution is significantly more balanced, the coefficient of income inequality falls from 0.41 to 0.21 and the income share of the population's poorest deciles increases more than fivefold. The results suggest that market income alone is a misleading measure of income distribution in Indonesia.     

Trade Opening,Fiscal Reforms,Poverty, and Inequality: A CGE Analysis for Bangladesh

We assess the short‐ and long‐run impacts of tariff reform policies on Bangladeshi households' poverty and income distribution by developing an 86‐sector, four‐factor, and nine‐household‐group computable general equilibrium (CGE) model. The main findings are that the complete removal of tariffs leads to a decrease in overall poverty with rich household groups in a relatively better position. In the short run poverty incidence increases for rural landless, urban illiterate, and low‐educated household groups whereas rural large farmer and urban medium household groups enjoy improvements in all poverty indicators. In terms of income distribution, trade liberalization enhances inequality slightly, but there is a tendency towards more equitable distribution in the long run. The choice of a fiscal compensatory mechanism with consumption tax is likely to play a negative role in terms of poverty and inequality in the short run; however, interestingly, the results are pro‐poor in the long run.     

Inequality in South Africa: The distribution of income,expenditure and earnings

This article empirically analyses the state of inequality in South Africa. International comparisons show South Africa to be among the most unequal countries in the world. The levels of income inequality and earnings inequality are analysed with a range of measures and methods. The results quantify the extremely high level of inequality in South Africa. Earnings inequality appears to be falling in recent years, with relative losses in the upper-middle parts of the earnings distribution. Decomposing income inequality by factor source reveals the importance of earnings in accounting for overall income inequality. The article concludes by observing that, internationally, significant sustained decreases in inequality rarely come about without policies aimed at achieving that, and suggests that strong policy interventions would be needed to reduce inequality in South Africa to levels that are in the range typically found internationally.     

Decomposing inequality and poverty in post-war Rwanda: The roles of gender,education, wealth and location

This paper provides an overview of poverty and inequality in post-war Rwanda. Rwanda is one of the poorest countries in the world, and has recently become one of the most unequal. High levels of poverty and inequality have important implications not only in terms of evaluations of social welfare, but also for management of social tensions and the propensity for violent conflict in the future. This paper uses the first two available and nationally representative rounds of household surveys –EICV1 2000 and EICV2 2005 – to decompose and identify the major ‘sources' of poverty and inequality in the country. I find stark differences in vulnerability to poverty by region, gender and widow status of the head of household. I additionally find important changes in the ‘income generating functions' of Rwandan households, and that distribution of land and financial assets are increasingly important in determining the inter-household distribution of income.     

Unemployment, Poverty and Income Disparity in Urban China

This paper studies the issues of unemployment and poverty that have been appearing recently in urban China. It estimates the urban unemployment rate, poverty rate and income disparity using a new sample survey data set. Meanwhile, it analyzes the relationship between unemployment and poverty, and the effects of poverty on urban inequality. The main findings are that: (i) the urban unemployment rate reached 11.6% in 1999 and was a major cause of urban poverty; (ii) growing urban poverty is becoming the significant source of worsening urban inequality; and (iii) migrant households have an increasing influence on urban poverty and the pattern of urban income distribution. The paper concludes that urban income distribution has worsened since 1995, and urban unemployment and poverty are the major factors in this worsening.     

Living costs,real incomes and inequality in colonial Jamaica

This paper provides the first quantitative assessment of colonial Jamaican real incomes and income inequality. We collect local prices to construct cost of living and purchasing power parity indicators. The latter lowers Jamaica's GDP per capita compared with the rest of the Atlantic economy. We also compute welfare ratios for a range of occupations and build a social table. We find that, being a net food importer, the slave colony had extremely high living costs, which rose steeply during the American War of Independence, and low standards of living, particularly for its enslaved population, but also for the free unskilled population that competed with slave labor. Our results also show that due to its extreme poverty for the many in the middle of great wealth for the few, Jamaica was the most unequal place yet studied in the pre-modern world. Furthermore, all of these characteristics applied to the free population alone.     

China＇s Pattern of Growth： Moving to Sustainability and Reducing Inequality

I. Introduction China’s gross domestic product (GDP) growth has averaged 9.4 percent per annum since1978. As a result of this impressive growth, millions of people were lifted out of poverty. Economic reforms implemented over the last 25 years have certainly been instrumental in the remarkable growth performance, leading to higher productivity growth than in the pre- reform period. Nevertheless, it is widely agreed that China’s growth during this period has been resource intensive, drawing…     

The rise and fall of worldwide income inequality, 1820–2035

The development process and the demographic changes that are a central element of it explain both the nearly two centuries of increasing income inequality prior to 2000 and the reversal of this trend that followed. There are at least four phases of the development process: (1) Malthusian pre-development, (2) initial growth, (3) improved productivity, and (4) receding growth. Prior to the industrial revolution, the entire world was in the Malthusian Phase 1. During 1820–1950, about 20 countries, mostly in Western Europe, North America, and Oceania, moved out of Phase 1 and began to grow more rapidly. But, per capita income levels in the rest of the world continued to stagnate and worldwide income inequality widened continuously for at least 150 years following the Industrial Revolution. Around 1960, developing countries began to escape the Malthusian trap and move into Phase 2 of development. By the latter part of the 20th century, many developing countries were achieving growth rates equal to or greater than the high-income countries, slowing the rise in inequality. By 2000–2015 most developing countries were in either Phases 2 or 3 of development, while most of the high-income countries were moving into Phase 4, leading to a sharp reduction in worldwide income inequality. The recent reductions in worldwide income inequality are likely to continue in the near term because of the continuation of the more favorable demographic changes in developing compared to high-income countries.     

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.     

Poverty, Inequality and Growth in Selected Middle East and North Africa Countries, 1980–2000

This paper uses crosscountry data and country-case studies to analyze trends in poverty, inequality and economic growth in the Middle East and North Africa (MENA) region. Compared to other regions, the MENA region has a low incidence of poverty and income inequality. Two factors account for this situation: international migration/remittances and public sector (government) employment. Since the early 1980s international migration to the Persian Gulf and Europe has helped boost the incomes of the poor in the Middle East. At the same time, many MENA countries have used government employment as a means of keeping people employed and out of poverty. Regression analysis of crosscountry data shows that both of these factors have a statistically significant impact on reducing the level and depth of poverty in the MENA region.     

Revisiting Growth‐Poverty Relationship: A Medium‐Term Causality Approach

This article examines the potential medium‐term causal relationship between changes in Gross Domestic Product (GDP) per capita and poverty in developing countries during the 1970s–1990s. For this purpose, we use panel data model evaluation techniques to test the out‐of‐sample forecasting performance of competing models. We conclude that the evidence supports the hypothesis that increases in GDP per capita cause unidirectional poverty reduction, measured by the $1/day poverty rate, in the period 1970s–1980s. The results are similar when analysing low‐ and middle‐income countries and mid‐high‐ and very high‐inequality countries separately. However, in the period 1980s–1990s, it is only statistically significant for low‐income countries.     

Decomposing Income Inequality and Policy Implications in Rural China

Using village data from samples covering 6 provinces,36 counties and 216 townships,the income inequalities within and between townships in rural China are assessed. The Theil index and the mean logarithmic deviation methods enable us to test income inequality at the township level,and to decompose it into intra-regional and inter-regional at county and provincial levels. In the present paper,we also decompose income inequalities between and within the nationally designated poor counties (NDPC). The results show that approximately two-thirds of the income inequality in rural China would be eliminated if measures and policies were targeted at the county level. This study also confirms the rationale that China's poverty alleviation strategy of focusing on poor counties based on the inequalities between NDPC and non-NDPC accounts for the most inter-province inequality.     

Roles of Income Polarization,Income Inequality and Ethnic Fractionalization in Social Conflicts: An Empirical Study of Indonesian Provinces, 2002–2012

Previous studies have cited inequality as a major factor relating to conflicts in Indonesia, while consideration of polarization and fractionalization as drivers of conflict is limited. The current paper examined the roles of three indices (polarization, inequality and fractionalization) in explaining the incidence of conflicts in Indonesian provinces over 2002–2012. This study used income (proxied by expenditure) differences to measure polarization and inequality, with subnational data as the unit of analysis. In addition, to complete the analysis, the present study used a variety of socioeconomic indicators as additional control variables. This paper verified that the high degrees of income polarization, ethnic fractionalization and income inequality are associated with the high probability of conflicts in Indonesian provinces. It also found that socioeconomic factors such as poverty, unemployment, population and natural resources, as well as some types of local government spending are significantly associated with conflicts.

A reconsideration of what and who is middle class in South Africa

In this paper, we revisit ‘what and who’ is middle class in South Africa using data collected in the 2008 National Income Dynamics Study. First, we consider how to identify the middle class based on two broad definitions adopted in the international economics literature: a middle class defined by the middle share of the national income distribution; and a middle class defined by an absolute level of affluence and lifestyle. We explore alternative ways of capturing the ‘middle income strata’ and we suggest an approach for identifying threshold levels of income associated with middle-class affluence. Second, we show that the size and the composition of the middle class in South Africa are both very sensitive to how the middle class is defined. In particular, we demonstrate that there is very little overlap between the two broad definitions, a finding which reflects very high levels of poverty and inequality in the country.     

The challenge of growth,employment and poverty in the South African economy since democracy: an exploratory review of selected issues

The welfare challenges in post‐apartheid South Africa are best represented by the triumvirate of poverty, income inequality and unemployment. In turn, the one generally accepted mechanism for overcoming these challenges is for an economy to realise sustained levels of high economic growth. Herein lie the essential coordinates of this article. We attempt first to describe the post‐apartheid experience with economic growth and its determinants. Secondly, we describe the nature of the welfare challenges that the society faces in terms of poverty, income inequality and unemployment. Finally, and perhaps most critically, we explore the various constraints on economic growth that may be hindering the realisation of higher standards of living amongst the population.     

Exploring the Impact of Energy Sources on Production,Inequality and Poverty in Simultaneous Equations Models for South Africa

Abstract: This work adapts per capita income, energy demand (sub‐group decomposed), inequality and poverty frameworks in a simultaneous equations setting to investigate the role of energy sources on per capita income, inequality and poverty in South Africa. It finds that energy sources (particularly electricity and diesel) are important in estimating production functions. Gasoline, kerosene and coal all exacerbate poverty, with the highest impacts on abject poverty. It is better to disaggregate energy sources in order to capture resource‐specific details. Redistribution efforts that focus on reduction of between‐group inequality can also moderate energy use since between‐group inequality tends to increase the demand for most energy sources. Public efforts are yielding fruits in this direction and should be encouraged. Access to energy sources like electricity, diesel and gas are crucial for productivity enhancement, but for them to yield significant anti‐poverty fruits, efforts must also target broadening capital access by the poor.
