Based on data for almost 300 households this paper explores associations among income diversification, household perceptions of livelihood risks, and changes in consumption outcomes across two points in time in post-famine Ethiopia. Four key questions are addressed: i) To what extent did households emerging from the famine period with relatively higher income and calorie consumption levels also have a more diversified income base?; ii) Was higher income diversification in 1989 associated with higher income and consumption levels by 1994?; iii) Which households increased their share of income from non-cropping activities most during the inter-survey years?; and iv) Did household heads perceive a lack of non-farm income activities to be an important risk factor in famine vulnerability? We find that wealthier households tended to have more diversified income streams; those initially more diversified subsequently experienced a relatively greater increase in both income and calorie intake; households with a greater concentration of assets were more likely to fall in their relative outcome ranking (as were female-headed households); and, initially less diversified households subsequently realized greater gains in income diversification. We also find suggestive evidence that personal perceptions of risk factors guided subsequent diversification decisions.  相似文献

This study draws on purposive survey data of approximately 600 households in peri-urban Tanzania to describe the degree and nature of non-farm diversification in these settings. With the exception of relatively dynamic cities such as Dar es Salaam and Arusha, overall non-farm incomes shares are not unambiguously higher than in rural areas as a whole. Non-farm income shares rise sharply and monotonically with quintiles defined in terms of per capita food consumption. In that sense the sector appears to offer an important route out of poverty. The evidence suggests that education, and access to infrastructure, are important determinants of non-farm incomes in peri-urban areas. Women appear to be poorly placed vis à vis the non-farm sector, even after controlling for education, age and other characteristics. Kinship and tribal affinities, and time devoted to communal activities, appear to deter entrepreneurial activity and non-farm employment, but trust in officials and public servants and strong heterogeneous village associations, are important in stimulating non-farm activity.  相似文献

This paper presents evidence on the effects of two different sorts of policy shocks on observed income diversification patterns in rural Africa. In Côte d’Ivoire, households with poor endowments were less able to respond to attractive emerging on-farm and non-farm opportunities. Due to entry barriers to superior livelihood strategies, the benefits of exchange rate reform accrued disproportionately to households that were richer prior to devaluation. By contrast, food-for-work transfers to households in Kenya significantly reduced liquidity constraints, enabling project participants to pursue more lucrative livelihood strategies in non-farm activities and higher-return agricultural production patterns. Jointly, these two shocks underscore the importance of liquidity, market access and skill constraints to skilled non-farm income sources to dynamic poverty traps in rural Africa.  相似文献

This paper examines how the distribution of earnings in rural Ghana and Uganda differs by income type and by gender. We find that non-farm earnings contribute to rising inequality, but that lower income groups also benefit due to strong overall growth in non-farm earnings. The inequality-inducing effect is driven by self-employment income; wage income, on the other hand, reduces inequality. The tendency of non-farm income to contribute to inequality is greater among female-headed households for whom self-employment is important and non-farm opportunities more constrained. Determinants of non-farm income are estimated and appear to be strongly related to location, education, age, and distance to market. Estimates of the linkages to agriculture in Ghana are weaker than expected, showing the non-farm sector to be functioning more as an alternative activity to agriculture than as a complement.  相似文献

Farm households diversify their income sources into off-farm wage employment motivated by low farm income and availability of surplus family labor, whereas they enter into off-farm self employment to earn an attractive return. Farm households have upward-sloping, although inelastic, off-farm labor supply curves. Therefore, increasing the availability of off-farm activities and improving the wage rate received by farm households can expand the economic activity of the Tigray Regional State. Due to entry barriers, relatively wealthy farm households may dominate the most lucrative rural non-farm activities such as masonry, carpentry and petty trade. Hence the underlying factors that hinder participation in non-farm activities such as credit constraints and lack of skill may have to be addressed through the provision of credit and technical training for the poor.  相似文献

This paper examines the impact of non-farm work on household income and food security among farm households in the Northern Region of Ghana. We analyze the impact by employing propensity score matching method that accounts for self-selection bias. The matching results show that participation in non-farm work exerts a positive and statistically significant effect on household income and food security status, supporting the widely held view that income from non-farm work is crucial to food security and poverty alleviation in rural areas of developing countries.  相似文献

This paper provides a micro-level foundation for discussions of land allocation and its relation to income poverty within the smallholder sectors of Eastern and Southern Africa. Results are drawn from nationally-representative household surveys between 1990 and 2000 in five countries: Ethiopia, Kenya, Rwanda, Mozambique, and Zambia. The paper shows that farm sizes are declining over time; that roughly a quarter of the agricultural households in each country are virtually landless, controlling less than 0.10 hectares per capita, including rented land; that non-farm income shares are below 40% even for the households in the bottom land quartile; and that because of this, there is a strong relationship between access to land and household income, particularly for farm sizes below 1.0 hectares per capita. Land distribution within these small-farm sectors appears to be becoming more concentrated over time, and their Gini coefficients are comparable to those of many Asian countries at the time of their green revolutions. Lastly, the largest part of the variation in per capita farm sizes within the small-farm sectors is, in every country, predominantly within-village rather than between-village. Realistic discussions of poverty alleviation strategies in Africa need to be grounded in the context of these land distribution patterns and trends.  相似文献

This is a study of tenure choice, housing demand and mobility in the submarkets of the Helsinki metropolitan area. The empirical analysis is based on data on households, type of tenure, housing characteristics and mobility for a sample of Helsinki residents at the end of 1980s. According to our results the probability of owning is affected not only by user costs of alternative tenure forms but also by permanent income and demographic variables. Results from the tenure specific housing demand models indicate that there are non-neutralities in the housing markets. Permanent income elasticities of housing demand are clearly positive in owner-occupied sector and systematically higher than in the rented sector. The demand for owner-occupied housing depends very strongly on the age of the household head. User cost per housing unit affects housing demand negatively in both tenure forms. Effective demand is greater in private housing sector. The results suggest that owner-occupied living is preferred with heavily subsidized households the least likely to move. In the rental sector, where the probability of moving is higher, it is also true that the most heavily subsidized households are the least likely to move.  相似文献

This paper presents panel data evidence on the impact of expansion of global value chains and large-scale export-oriented farms in developing countries over almost a decade. We estimate the income effects of wage employment on large-scale farms in the horticultural export sector in Senegal, using data from two survey rounds covering a seven-years period of rapid expansion of the sector. We estimate average income effects as well as heterogeneous income effects, using fixed effects and quantile fixed effects regressions. We find that poverty and inequality reduced much faster in the research area than elsewhere in Senegal. Employment in the horticultural export sector is associated with higher household income and the income effect is strongest for the poorest households. Expansion of the horticultural export sector in Senegal has been particularly pro-poor through creating employment that is accessible and creates substantial income gains for the poorest half of the rural population. These pro-poor employment effects contrast with insights in the literature on increased inequality from rural wage employment.  相似文献

This paper uses new survey data to investigate the covariates of self-reported switching costs and switching behavior by deposit account holders. Factors affecting geographic mobility appear to be most important in explaining the duration of deposit relationships. Both younger and older respondents are more likely than others to be at their first bank ever, suggesting a cohort effect in deposit relationships. Households reporting switching costs, net of the benefits from switching, are less likely than others to have stayed with a bank for prices or customer service, suggesting that switching costs may decrease price sensitivity. Switching costs appear more severe for households with high income or education and for households with very low income or minority ethnicity. These findings imply that banking markets characterized by such households may present greater entry costs for new firms.  相似文献

Drawing insights from the literature on transformation of rural non-farm employment, pathways from agriculture to nutrition, and linkages between migration and nutritional status of household, we seek to understand differences in dietary diversity across three mutually exclusive types of rural Indian households: where all members work in rural areas, at least one member commutes to urban areas, at least one member has no fixed place of work. Our analysis is based on a nationally representative data set from India for the year 2009–10 and we use propensity score matching methods. We find that as compared to households with no commuters, households with rural–urban commuters have higher dietary diversity; whereas households with no fixed place workers have lower dietary diversity. We also find differences in dietary diversity across households which differ by their primary source of income.  相似文献

A variety of reverse mortgage loan programs have been available to elderly households for over a decade. The number of unrestricted reverse mortgage loans issued by the private sector has been quite small. About 12,000 loans have been issued through mid-1992. Some researchers take this to mean that the size of the potential market for reverse mortgages is also quite small. Other researchers claim that current low levels of activity reflect supply and demand problems, but that the potential market is in fact quite large. This paper uses American Housing Survey (AHS) data to estimate the potential size of the market for unrestricted reverse mortgages. The 1989 national AHS shows that there are over twelve million elderly homeowners (age 62 and over) who own their homes free and clear. Depending on their income, age and the level of home equity, the group of households most likely to benefit from reverse annuity mortgages is considerably smaller. As one approach to defining a lower bound of the estimate of potential beneficiaries from reverse mortgages, we count the number of homeowners in a prime group consisting of the older elderly, aged 70 or above, with an annual income of $30,000 or less, with home equity between $100,000 and $200,000, who have lived in their homes for over ten years. We estimate that there are about 800,000 elderly households in this prime group. For such households, reverse mortgage payments could represent a substantial percentage increase in income; other definitions of target groups can also be explored using the tables provided. The paper uses the 1985 through 1988 AHS Standard Metropolitan Statistical Area (SMSA) surveys to identify areas that have a large number of elderly homeowners in the prime target group, and in which these homeowners represent a large fraction of the elderly homeowner population. These locations are likely targets for introduction of reverse mortgage products because any campaign can be targeted towards a high concentration of likely eligible beneficiaries.  相似文献

Food systems in developing countries are changing rapidly with a growing role of modern supermarkets. Supermarkets influence supply chains and the way agricultural products are sourced from farmers. Especially for the procurement of fresh fruits and vegetables, supermarkets often contract farmers directly to ensure consistent and high-quality supply. One important question, which is addressed here, is whether smallholder farmers benefit from supermarket contracts. Previous studies address this question, but mostly focus on income effects without exploring implications for other dimensions of household welfare, such as nutrition, health, or housing conditions. Moreover, most existing studies rely on cross-section data. We add to the literature by analyzing effects of supermarket contracts on income and multidimensional poverty using three rounds of panel data collected from smallholder vegetable farmers in Kenya and econometric models with household fixed effects. On average, supermarket contracts increase household income by over 40%. We also find significant reductions in income poverty and multidimensional poverty. Quantile regressions show that farmers in all income groups benefit, but richer households benefit more than poorer ones in absolute terms. However, supermarket contracts cause the strongest reductions in multidimensional deprivations among the poorest households.  相似文献

The telecommunication sector in Mexico was highly concentrated until 2013. The sector was mostly composed by a dominant player, a rationed market (low density of services), a poor institutional design, high tariffs, and weak regulation agents. The Herfindahl-Hirschman (HHI) index was 5333 for mobile telephone and 7,029 for fixed telephone services—among the highest scores in the world. In order to promote competition in the sector, Congress approved a reform in 2013 to establish a new regulator empowered to impose asymmetrical rules in the case of the predominance of a single firm. A declaration of preponderance of the dominant player was issued, promoting free interconnection rates and the mandatory sharing of its passive and active infrastructure with the rest of the firms in the industry. The new institutional design led to increased competition in the sector, decreasing the mobile and fixed telephone prices while increasing the coverage and penetration of these services. In this article, an applied general equilibrium model for the Mexican economy is employed to assess the impact of the Telecommunication Reform in Mexico in the telephone sector, consumer welfare, and income distribution. The model is static, encompassing 10 types of consumers (rural and urban and the five income quintiles) and 40 sectors (of which four are disaggregate telecommunications industries). It assumes fixed wages and capital rental prices as well as idle resources. The main results indicate that the effects of the reform are not minor; the drop in telephone prices would reduce the general consumer price index by almost 2%, and the value added would increase by more than 3%, benefiting mainly households in the highest income quantiles.  相似文献

In American metropolitan areas, households are highly mixed by income with higher average incomes at greater distances from downtown. Also, suburbs attract families with children, while poor households and small households with young heads select sites close to the commercial core. These empirical observations and others are predicted by this standard model of a monocentric city with three major modifications. Time at work is controlled by employers, not employees. Households with more members at home consume in the same house more housing services. Finally, lot prices need not be proportional to area. In the resulting equilibrium, households are mixed by income and separated by family size. This contrasts with classic urban models where households are separated only by their workers' wage rates.  相似文献

Because food insecurity is primarily a problem of low household incomes and poverty, and not just inadequate food production, projects and programs for food insecure African farmers which aim at increasing production of subsistence crops may be ineffective. Instead, government should look for ways to improve returns to farmers' resources in a broader context, which may include expanded opportunities for non-farm microenterprises and agricultural labor. This has been the conventional wisdom since the writings of Amartya Sen. Still unclear, however, are the implications of his thinking for the roles of African women farmers who are traditionally the food-crop producers in Africa and are often food insecure. Immediate expansion of income-earning activities such as cash cropping and non-farm microenterprises may not be possible for women in male headed households in many African societies where cash income is seen as part of the male domain. In addition, women farmers may need a long adjustment period to diversify their income sources fully because most African countries are at the early stages of structural transformation. Different developmental interventions, both in policy and in technology, are therefore needed to address food security and economic transformations in Africa in the short and long term.  相似文献

Since the seminal works of Malthus and Boserup, scientists have long debated the impact of population growth and land constraints on the wellbeing of rural people. Today these concerns are particularly relevant to Africa, with its rapid population growth, very small farms, and chronic food insecurity. In this paper we examine adaptation to falling land-labor ratios using a comprehensive theoretical framework in which households faced with binding land constraints can respond in three ways: intensifying agricultural production, diversifying out of agriculture, and reducing fertility rates. Using cross-country data and drawing upon the existing literature, we reach three conclusions. First, population density is associated with reduced fallows and more intensive use of land but not fertilizer use or irrigation, indicating major challenges in achieving sustainable intensification or agricultural productivity growth. Second, there is little evidence of successful non-farm diversification in response to land pressures in Africa from domestic or international income sources. Third, rural Africans in land constrained countries desire smaller families, but have thus far benefited little from family planning policies. These findings underscore the need for a coordinated multi-sectoral approach to sustainably reduce poverty in the region.  相似文献

This paper provides a model-based assessment of local and global climate change impacts for the case of Yemen, focusing on agricultural production, household incomes and food security. Global climate change is mainly transmitted through rising world food prices. Our simulation results suggest that climate change induced price increases for food will raise agricultural GDP while decreasing real household incomes and food security. Rural non-farm households are hit hardest as they tend to be net food consumers with high food budget shares, but farm households also experience real income losses given that many of them are net buyers of food. The impacts of local climate change are less clear given the ambiguous predictions of global climate models (GCMs) with respect to future rainfall patterns in Yemen. Local climate change impacts manifest itself in long term yield changes, which differ between two alternative climate scenarios considered. Under the MIR scenario, agricultural GDP is somewhat higher than with perfect mitigation and rural incomes rise due to higher yields and lower prices for sorghum and millet. Under the CSI scenario, positive and negative yield changes cancel each other out. As a result, agricultural GDP and household incomes hardly change compared to perfect mitigation.  相似文献

Many African countries have recently experienced rapid growth in the numbers of medium- and large-scale farms. These developments have generated considerable speculation about the impacts of farmland concentration and inequality on smallholder households and communities. This study exploits inter-district variation in farm landholding patterns in Tanzania to determine how differences in localized farmland structure affect rural household incomes using nationally representative household panel survey data. Because farm structure is a multifaceted concept, five alternative indicators of farmland structure are defined for 142 districts in Tanzania: (i) the Gini coefficient; (ii) skewness; (iii) coefficient of variation; (iv) share of controlled farmland under medium-scale farms; and (v) share of controlled farmland under large farms. These alternative farm structure variables are included in models of rural household income to test their effects after controlling for available household and community covariates. The study highlights four main findings. First, most indicators of farmland concentration are positively associated with rural household incomes. Second, household incomes from farm and non-farm sources are positively and significantly associated with the share of land in the district controlled by farms in the 5–10 and 5–20 ha category. Third, these positive spillover benefits are smaller and less statistically significant in districts with a relatively high share of farmland controlled by farms over 20 ha in size. Fourth, poor rural households are least able to capture the positive spillovers generated by medium-scale farms and by concentrated farmland patterns.  相似文献
