Consumption based estimates of urban Chinese growth

This paper estimates the household income growth rates implied by food demand in a sample of urban Chinese households in 1993–2005. Our estimates, based on Engel curves for food consumption, indicate an average per capita income growth of 6.8% per year in 1993–2005. This figure is slightly larger than the 5.9% per year obtained by deflating nominal incomes by the CPI. We attribute this discrepancy to a small bias in the CPI, which is of a similar magnitude to the one often associated with the CPI in the United States. This result supports the view that Chinese price statistics are reliable. Our estimates indicate stronger gains among poorer households, suggesting that urban inflation up to 2005 in China was “pro-poor,” in the sense that the increase in the cost of living for poorer households was smaller than for the average one.     

Understanding urban poverty in two high-density suburbs of Harare,Zimbabwe

ABSTRACT

Urban communities are heterogeneous and averages mask inequities and deprivations among poor and rich urban communities. This article examines the situation of households residing in two low-income, high-density suburbs of Harare, Zimbabwe. The aim of the research was to contextualise urban poverty by looking at selected urban communities and vertically analysing the patterns and determinants of poverty. A household survey was administered to 1000 households and qualitative data were collected through focus group discussions and key informant interviews. The study found high levels of income poverty and also found differences in poverty experiences between the two suburbs. The major proximate determinants of poverty were large family size; low education level of the household head; lack of income from permanent employment; low cash transfers; and short length of residence in the suburb. Increasing household income consumption can be addressed through scaling-up industries, which would result in more quality employment.     

Milk in the city: profiles and development paths for urban dairy holders in Ethiopia

ABSTRACT

Demand for dairy products is growing fast in urban areas. Due to poorly developed rural infrastructure, urban dairy farms are pivotal in making milk available and affordable in towns and cities. Yet current supply fails to meet the increasing demand. In order to formulate fit interventions that can expand urban dairy production, a detailed understanding of urban dairy systems is needed. Using a cluster analysis approach, we profile 304 urban dairy farms in Mekelle, Northern Ethiopia, along three dimensions: input efficiency, market integration, and resilience towards demand seasonality. Our results suggest five distinctive farm types: surviving farms, processing female farms, young male entrepreneurs, established output-efficient farms, and established output-input-efficient farms. We observe large discrepancies in terms of dairy enterprise’s productivity, profitability, and suitability in future urban policy planning. For each of the identified dairy systems, we sketch potential intervention approaches that can feed into more tailored dairy development programmes.     

Estimating the impacts of rising food prices on nutrient intake in urban China

The nutritional impacts of rising food prices on urban households across income classes are assessed using the 2004 NBS urban household survey data for Jiangsu province of China. Empirical results from this study suggest that the across-the-board food price increase is expected to have a substantial adverse impact on nutritional well-being of urban households and in particular, the poor. Moreover, an increase in the price of food grains alone will have the largest adverse impact on calorie and protein intakes, whereas an increase in price of oils and fats only will induce the largest reduction in fat intake.     

Family formation and economic insecurity among youth in South Africa

ABSTRACT

Youth unemployment continues to be a burden and concern for the South African government. Being economically insecure, the situation is dire with the government needing to provide resources to a population who should be economically independent. There is a need to look at the social determinants of economic insecurity among youth in South Africa. Family formations could either promote or inhibit economic well-being. This article aims to assess whether economic security improves as youth enter into unions and/or have children. The South African National Income Dynamics Study is used. Unmarried youth with no children are measured at baseline (2008) and followed up over time to examine whether economic security status changes as union status changes. Results show that while economic security, employment (from 7.61% to 25.67%) and net income per month (from 19.48% to 32.79%) increase over time, youth who marry but have no children have the lowest risk of economic insecurity (relative risk ratio?=?0.02, p < 0.05) compared with those who remain unmarried but have children. Special attention needs to be given to youth who have children and are unmarried and among those who marry and have children soon after.     

Polygynous family system,neighbourhood contexts and under-five mortality in sub-Saharan Africa

ABSTRACT

Based on the competing theories regarding the relationship between family structure and child health outcomes, this article examined the effects of polygynous family system (PFS) on under-five mortality (U5M) across different socio-economic and neighbourhood contexts in selected sub-Saharan African countries. Cox proportional regression analysis was performed on pooled data of children (n?=?54 842) born in the five years before the Demographic and Health Surveys of selected countries. Results indicated differential effects of PFS on U5M across varying contexts, because risks of U5M were significantly higher for children of polygynous mothers in poor communities (hazard ratio: 2.98, 95% confidence interval: 2.23 to 3.95, p?<?0.001) and children of monogamists in poor communities (hazard ratio: 2.24, 95% confidence interval: 1.69 to 2.98, p?<?0.001) compared with the children of monogamists in rich communities. Given the worsening effects of polygyny on childhood survival across different contexts, this study stressed the need for marriage reforms and enforcement of a monogamous family system if significant U5M reduction would be achieved in sub-Saharan African countries during the post-2015 development era.     

Mercantilism and urban inequalities in eighteenth-century Sweden

Abstract

It is sometimes argued that inequality promotes growth. If savings are the key to economic growth and the marginal propensity to save rises with income, a more unequal society will save more and grow faster. Thus, by sacrificing equality and concentrating income and wealth in the hands on the entrepreneurial class, society might enjoy higher economic growth. The economic policies taken by the Swedish state during the eighteenth century had the explicit goal of concentrating trade and opportunities for income formation and capital accumulation in the hands of the merchant class. Both an older tradition as well as recent research have emphasised the positive sides of these policies, as the privileged merchants are depicted as dynamic engines of growth and an important factor in the process of capital accumulation. However, in this paper it is argued that this assertion is not warranted. The mercantilist policies resulted in neither measurable per capita growth nor dynamic transformation but in institutional rigidities and the enrichment of the rich and impoverishment of the poor, leading to increasing urban inequalities.     

Working Women in an Urban Setting: Traders,Vendors and Food Security in Accra

Data collected from a 1997 household survey carried out in Accra, Ghana are used to look at the crucial role that women play as income earners and securing access to food in urban areas. One-third of the households surveyed are headed by women. For all households, women's labor force participation is high with 75% of all households having at least one working woman. The high number of female-headed households and the large percentage of working women in the sample provide a good backdrop for looking at how women earn and spend income differently than men in an urban area. Livelihood strategies for both men and women are predominantly labor based and dependent on social networks. For all households in the sample, food is still the single most important item in the total budget. Yet, important and striking differences between men's and women's livelihoods and expenditure patterns exist. Compared to men, women are less likely to be employed as wage earners, and more likely to work as street food vendors or petty traders. Women earn lower incomes, but tend to allocate more of their budget to basic goods for themselves and their children, while men spend more on entertainment for themselves only. Despite lower incomes and additional demands on their time as housewives and mothers, female-headed households, petty traders and street food vendors have the largest percentage of food-secure households. Women may be achieving household food security, but at what cost? This paper explores differences in income, expenditure and consumption patterns in an effort to answer this question, and suggests ways that urban planners and policy makers can address special concerns to working women in urban areas.     

Rural–urban migration and urbanization in China: Evidence from time-series and cross-section analyses

Since 1978, China has experienced a rapid and unprecedented process of urbanization, created by the history's largest flow of rural–urban migration in the world. This article attempts (a) to assess the role of the cityward migration in China's urbanization in 1978–1999 and (b) to empirically investigate factors behind the migration boom with time-series and cross-section data. We find that (a) rural–urban migration made dominant contributions to Chinese urban population growth; (b) while moving together with the Chinese economy, the causal link runs from economic growth to migration, not vice versa; (c) interprovince migrants were encouraged by the rural–urban income gap and discouraged by their geographic distances to destinations; and (d) the amount of intraprovince migrants is positively related to rural–urban income gap and urban population in that province.     

Wage differentials between urban and rural-urban migrant workers in China

Since the end of the 1980s, the number of migrants working in the urban labor market has increased dramatically. However, migrant workers are treated differently from urban workers. In this paper we examine the labor market discrimination against rural migrants from the point of view of wage differentials using CHIP-2007 data. We apply Jann pooled method to deal with index number problem and use Heckman two step model to correct selection problem when decomposing the wage gap. The decomposition results show that a significant difference in wage gains persists between the two groups as late as 2007. In 2007 migrants only earned 49% of urban workers' income and 17% of the wage gap cannot be explained by observed factors. In detail, differences in educational attainment, work experience and distribution across industry, occupation, and ownership of enterprises account for most of the explained wage gap.     

Individual well-being in urban China: The role of income expectations

Using household survey data, we study the determinants of individual well-being in urban China, emphasizing particularly the role of income expectations. First, we find that individual well-being increases contemporaneously with own income and decreases with community's average income, consistent with findings reported in previous studies. This result holds when we replace income with consumption and when we consider employment and health status of other family members. Second and more important, we find that income expectations have a positive and significant effect on individual well-being. This result is robust to alternative model specifications and to controls for optimistic personality. Instrumental variable estimates and endogeneity tests suggest that the positive relationship between well-being and income expectations is genuine. Our finding has the potential to explain why reported well-being has declined in China despite the spectacular economic growth in the past decades.     

Broiler production in an urban and peri-urban area of Zimbabwe

ABSTRACT

Broiler chicken production is an important livelihood option for urban households in Zimbabwe. A study was carried out to document the technical, demographic and socio-economic parameters characterising the production of broilers in an urban area of Zimbabwe. Findings showed that producers have quite diverse livelihoods and broiler production is not restricted to a survival strategy for the urban poor with no livelihood alternatives, but mostly involved the more privileged. Access to start-up capital and property ownership were pre-requisites for the business. Broiler units were small-scale, informal, backyard businesses dominated by women. Flock sizes averaged 398 (range 25–3500) birds per cycle. However, 79% of the producers kept at most 200 birds per cycle. The mean stocking density was 9.5?birds/m² and reported mortality averaged 7.4%. Respondents have ad hoc marketing arrangements, and face constraints with regard to lack of sectoral support, shortage of capital, prohibitive council by-laws, market access and disease. Poultry production is therefore an important livelihood and business option in the urban and peri-urban area studied.     

Urban Shopping Patterns in Indonesia and Their Implications for Small Farmers

In developing countries, the expansion of supermarkets and other modern food retailers has raised concerns about the potential impact on traditional retailers and fruit and vegetable farmers. Will small farmers, in particular, be squeezed out of this growing, remunerative market by the quality standards imposed by supermarkets? In an attempt to answer this question, we analyse data from a stratified random sample of 1,180 urban households in Indonesia. We find that only a small share of fruits and vegetables are purchased from modern outlets, even among high-income urban households. On the basis of the relation between income and shopping patterns in our data, we project that even after 15 years of income growth, supermarkets will account for less than 40% of urban food spending. The impact of supermarket standards on small farmers may be less dramatic than has been feared.     

Poverty, Place or Race: Causes of the Retail Gap in Smaller U.S. Cities

In this study we explore the possibility that any or all of three dimensions of the U.S. inner city, central location, relatively low income, and a relatively high percentage of minority residents, correlate with a relative lack of neighborhood retail services, the so-called retail gap. Our empirical analysis is based on zip code level data for 39 U.S. cities with populations from 50 to 225 thousand people. After specifying an empirical model based on hypotheses drawn from the urban economics, urban studies, and urban development literature, we test access to retail services using both geographical density and per capita retail measures. While several results from this study are worthy of discussion, our primary empirical finding is that neighborhoods with high percentages of African-Americans are systematically under-served by retail, all else equal, while Latino, low income, or otherwise centrally located neighborhoods are not. We then test a selection of product categories for retail density, finding some differing results by product category but verifying our more general conclusions for most products. Finally, we find that grocery stores have significantly smaller scale in African-American communities, a finding that provides partial support for the urban “food desert” hypothesis. These findings suggest that the inner city retail gap may be more of a racial than geographic issue, and that increased emphasis on racial composition is warranted in the retail development policies applied to smaller U.S. cities.     

Informal employment and its effect on the income distribution in urban China

This paper discusses the issue of informal employment and its effect on the income distribution in China using datasets from the China Urban Labour Surveys of 2005 and 2010. Based on a new definition of informal employment, we estimated the proportion of informal employment relative to total non-agricultural employment in urban China and found it to be 49.7% in 2005 and 40.3% in 2010. Meanwhile, our study illustrated that informal employees' earnings were 67% that of formal employees, and this large earnings gap raised the Gini coefficient to 0.42 in 2005. The Blinder–Oaxaca decomposition result shows that the earnings gap explains more than half of the overall personal income inequality in urban China. These results indicate that informal employment has a significant effect on the income distribution in urban China. Consequently, regulating the labour market, eliminating job discriminations and legislating the informal employment should be considered as alternative means of reducing inequality in China.     

Socio-Economic Impact of Super Typhoon Harurot in San Mariano, Isabela, the Philippines

This paper reports on the socio-economic effects and coping mechanisms of farm households affected by super typhoon Imbudo in San Mariano, Isabela, the Philippines. Estimations of economic losses are given based on 150 interviews among the rural population. The relative loss per crop as part of the annual household income for yellow corn, banana, and rice were 64%, 24%, and 27%, respectively. Unexpectedly, most farm households did not change their agricultural strategies and continued with “business as usual” (78%). The main explanation for this lack of adaptation is found in the cultural and societal structure of farm households and their traders. This paper concludes with a short-term and long-term vulnerability and resilience analysis for the households, the socio-agricultural system, and the ecological system.     

Commute time and subjective well-being in urban China

Using data from the 2010 China Family Panel Studies, this study investigates the association between commute time and subjective well-being in a sample of 16- to 65-year-old employees in urban China. We find evidence that a longer commute time is associated with lower levels of both life satisfaction and happiness, especially when the commute times are extreme (≥ 1 hour per day). A multiple mediation analysis further indicates that the relation between commute time and happiness is partially mediated by the time spent on daily activities, particularly sleep. We also calculate the amount of income necessary to compensate an employee's loss in well-being at approximately 82 yuan per hour of commute time, implying that in urban China the annual loss of well-being amounts to around 10 billion yuan.     

Food Price Crisis,Poverty, and Inequality

This paper simulates how a doubling of food prices affects absolute poverty and the food‐price‐adjusted real income distribution. We assume unsubsidized world food prices in order to derive the cost of poverty deepening and poverty expansion. We also estimate the degree to which inequality increases if no measures are put in place to offset rising food prices. Both measures are vulnerability indicators useful for social policy planning. Our results show that low‐income countries experience dramatic increases in absolute poverty as a result of doubling food prices. Middle‐income countries experience the greatest decrease in absolute income, which contributes most to an increase in world income inequality. The paper estimates that the global dollar value of the absolute poverty gap ($1.25/day) has the potential to increase by 400%, with poverty deepening accounting for two thirds of the increase.     

我国居民收入分配的格局——帕雷托分布方法

本文为确定一个时期内总体收入分配或特定部分的收入分配究竟是否趋向两极分化和比较中间收入等级和高收入等级的分配份额提供了方法。用帕雷托分布拟合我国1988年和1995年两年的居民收入分配。发现1995年和1988年相比：（1）没有明显证据表明农村居民收入存在两极分化．城镇居民在排除了收入最低的10％人口后，有明显的两极分化趋向；（2）中间等级收入份额减少。收入向高收入者集中；（3）高收入者内部收入分配差别扩大；（4）社会成员在不同的收入等级之间的流动更加容易。
