In many areas of Africa, rural livelihoods depend heavily on subsistence farming. Using improved agricultural technologies can increase productivity in smallholder agriculture and thus raise household income and reduce poverty. Data from a nationally representative rural household survey from 2005 is used to assess the impact of four technologies – improved maize seeds, improved granaries, tractor mechanization, and animal traction – on household income in Mozambique. To ensure the robustness of the results, three econometric approaches were used: the doubly-robust estimator, sub-classification and regression, and matching and regression. The results show that, overall, using an improved technology did not have a statistically significant impact on household income. This may be associated with a widespread drought that occurred in 2005. Despite drought, distinguishing between households based on propensity score quintiles revealed that using improved technologies, especially improved maize seeds and tractors, significantly increased the income of those households who had better market access. Thus, to allow households to benefit from the use of improved technologies, policy makers need to reduce structural impediments to market participation by ensuring adequate road infrastructure and enabling access to markets.  相似文献

Access to ICT-based market information is crucial to the adoption of agricultural seed technologies for maize, beans and groundnut and to improve smallholder farmer yields and income. This ICT-based market information is provided by FM radio stations and by market information centers through media such as mobile phones and internet facilities, etc. Factors that positively affect the probability of access to ICT-based market information include access to microfinance loans, membership in a farmer association, government awareness campaigns, and wealth. Distance to the trading centers or district capital negatively affects this access. The likelihood of access to ICT-based market information declines with female-headed households. Access to market information has a positive and significant impact on the intensity of adopting improved seed for all crops. Adoption of improved seed has a positive and significant effect on farm yields and gross farm returns. This research shows that in order to generate meaningful improvements in food security and farm incomes, there must be commensurate efforts to promote ICT-based market information along with yield-augmenting agricultural seed technologies.  相似文献

It is well-established that armed political conflict has a detrimental effect on food security and household welfare: conflict induces food insecurity by reducing own food production, access to food through the market, and various other resources to sustain healthy and productive lives. One way of mitigating these adverse effects is to provide food aid. In this study we evaluate the impact of a World Food Programme intervention on household food security and asset protection among conflict-affected households in Northern Uganda. We employ propensity score matching to estimate the average treatment effect on food expenditure, food consumption and preservation of assets using a sample of 1265 observations from a 2008 survey. Our results reveal that the operation’s system of targeting beneficiaries was effective and in accordance with programme objectives. Food aid considerably reduced food expenditure of households, suggesting that recipients were net buyers of food, and that the food aid received was effectively consumed within the household. A corresponding positive effect on non-food expenditure was not found. Our results also indicate that food aid was effective in increasing meals consumed and in avoiding distress destocking of low value assets, but, surprisingly, only for male headed households.  相似文献

Exploring effective measures to promote rural household consumption is a challenge for developing countries, where rural areas often face severe financial exclusion and undeveloped commercial services. In this research, the influence of mobile payment, a popular payment method emerging in recent years, on rural household consumption is assessed by adopting China Household Finance Survey of 2017. Estimation results under the instrumental variable method suggest that mobile payment has a statistically significant and facilitating effect on rural household consumption in China. This positive effect is attributed to the benefits of mobile payment in improving financial inclusion and the convenience of consumption activities for rural areas, which is verified by performing several disaggregated analyses in our study. This work provides new evidence for the increasing literature on the economic impact of financial technology and several enlightenments for developing countries to improve the quality of public life through information intervention policies.  相似文献

The scope of a wholesale market may, in addition to demand- and supply-side substitution at the wholesale level, also be determined by substitution patterns at the retail level. Considering wholesale broadband access markets, it is argued that each of these forces can be strong enough to render a 5–10% price increase by a hypothetical monopolist at the wholesale level unprofitable and thus may lead to a wider wholesale market definition including, for example, cable networks in addition to DSL. Based on the theory of derived demand elasticities the paper discusses under which circumstances this could be the case. The position of the European Commission and the practice of national regulatory authorities are then reviewed in light of these arguments.  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

This paper reviews the evidence on smallholder market participation, with a focus on staple foodgrains (i.e., cereals) in eastern and southern Africa, in an effort to help better identify what interventions are most likely to break smallholders out of the semi-subsistence poverty trap that appears to ensnare much of rural Africa. The conceptual and empirical evidence suggests that interventions aimed at facilitating smallholder organization, at reducing the costs of intermarket commerce, and, perhaps especially, at improving poorer households’ access to improved technologies and productive assets are central to stimulating smallholder market participation and escape from semi-subsistence poverty traps. Macroeconomic and trade policy tools appear less useful in inducing market participation by poor smallholders in the region.  相似文献

This paper examines the capacities of smallholders in Nicaragua to exploit new linkages to certified coffee markets following the coffee crisis. Data on livelihood assets were collected from 292 households, which were clustered to test how differences in outcomes (asset building) reflect variations in initial asset endowments. The results suggest that most households built particular elements of their asset base and increased their resilience to future shocks. However, households struggled to make effective use of the gains for intensifying their livelihoods. Of the least-endowed households, few made investments in the scale or productivity of coffee, and most continued to depend heavily on subsistence production and seasonal off-farm income for survival. In conclusion, improved market access alone, even under relatively favorable market conditions and with considerable external support, will have uncertain impacts on rural poverty if the underlying constraints on household assets and investments are not addressed concurrently.  相似文献

We analyze a data set (on grocerystore prices for lettuce) with many advantages overthose used previously to explain firm heterogeneity inthe size and frequency of price changes. Despitecommon shocks to their input price, grocers' pricechanges vary widely in size and frequency. We testhypotheses emerging from a theoretical framework. Wefind that product, firm, and market characteristicsassociated with the benefits from and costs ofchanging price explain grocer-to-grocer variation inthe size and frequency of price changes. Moreconcentrated markets, larger firm size, and thinnerproduct markets lead to infrequent and large pricechanges.  相似文献

An understanding of consumer market segments is important for efficient and effective targeting of new technologies, such as biofortified foods. In this paper, we use cluster analysis to identify distinct consumer segments in Rwanda for four biofortified iron bean varieties. Data on consumer liking of various sensory attributes of beans was collected by using a 7-point hedonic scale through the application of home-use and central location tests implemented in two rural and two urban locations. Cluster analysis reveals the existence of several distinct consumer segments in each one of the four study locations. Further analysis is conducted by using multinomial probit and logit models to predict consumer segment membership based on the consumer characteristics. Results reveal that, depending on the location, consumer’s source of income and whether or not they received information about nutritional benefits of the iron bean varieties have a bearing on their preference of these varieties. The paper presents a profile of each one of the consumer market segments identified to assist targeting of various iron bean delivery, marketing and promotion efforts in Rwanda.  相似文献

Research on household food grain sales behavior in developing countries has tended to focus on the roles of market access and prices to explain why many rural households do not sell staple crops, though recent literature suggests that low household asset endowments may also be key constraints. We use econometric analysis of panel data from smallholders in Kenya, Mozambique, and Zambia to inform the design of public investments that will enable smallholders to increase their maize sales. Results show that investments that raise farm-level productivity and land access are an essential complement to investments that improve market access.  相似文献

To clarify the nature of the effect of firm innovativeness on business performance, this study draws on contingency theory and an interactional perspective to develop a conceptual framework to investigate how the interaction between market turbulence and competitive intensity moderates the relationship between firm innovativeness and business performance. This study used survey data from a sample of 154 high-tech manufacturing firms in Taiwan and employed hierarchical moderated regression analysis to test the hypotheses developed. The results reveal that the effect of firm innovativeness on business performance varies across the different configurations of market turbulence and competitive intensity. Specifically, the performance effect of firm innovativeness is most positive under high market turbulence and high competitive intensity; the performance effect is least positive under low market turbulence and low competitive intensity. However, the performance benefits of firm innovativeness fail to materialize under low market turbulence and high competitive intensity. Overall, these findings highlight that market turbulence and competition jointly influence the direction and strength of the performance effect of firm innovativeness. This study advances firm innovativeness research by identifying the configurational market conditions that augment or limit the value of firm innovativeness.  相似文献

Agricultural productivity and farmer welfare in developing countries is constrained by a multitude of market imperfections. Value chain development (VCD) is receiving much attention as a market-based policy instrument that can potentially address multiple of these constraints simultaneously. This paper provides a conceptualization of VCD and discusses how VCD can be used as a policy instrument. As an illustration, the paper describes the VCD project “SAFAL,” which uses an integrated approach to directly intervene in aquaculture, horticulture, and dairy value chains in South-West Bangladesh. The strategy is to first identify a demand downstream in the value chain and then to identify and reduce the constraints experienced by value chain actors upstream to meet this demand. Using a matched difference-in-difference methodology, this paper estimates farm household participation in SAFAL increases farm income and shortens the hungry season.  相似文献

Public–private partnerships are increasingly seen as an important tool to build agri-food supply chains and develop markets for agri-food products in emerging economies. However, many of these initiatives fail when the public component of the program ends. One exception is the USDA Market Assistance Program (MAP) that facilitated the redevelopment of the Armenian dairy sector after privatization. This paper presents a case study of this initiative and hypothesize that the USDA MAP facilitated farmer investment in private enforcement capital. This investment resulted in sustainable market relationships between farmers and dairy processors even after the USDA MAP expired. We find empirical evidence to support this hypothesis using a panel dataset collected from 172 Armenian dairy farmers in 2004 and 2009.  相似文献

Despite rapid population growth, increasing land pressure and urbanization, farmers in Sub-Saharan Africa have not intensified their production in a sustainable manner and farming systems remain predominantly subsistence-oriented. In response, developing country governments increasingly implement programs that promote crop intensification and more commercially-oriented agricultural systems. Rwanda’s Crop Intensification Program (CIP), launched in 2007, is one such example. However, despite its apparent success in raising production of several priority crops, there are legitimate concerns about the food and nutrition security implications for households that are encouraged to consolidate their land, specialize in their production, and increasingly rely on markets for their food needs. Using recent household survey data and a propensity score matching difference-in-differences method, we find that participation in land consolidation activities had ambiguous consumption effects: it positively impacted on consumption of roots and tubers, but had a negative effect on meat, fish and fruits consumption and the potential availability of vitamin B12 in participants’ diets. This calls for a review of CIP implementation practices to enhance the program’s food and nutrition security outcomes, with improvements in market functioning and market access being potential starting points.  相似文献

Net neutrality rules have been implemented in many developed countries, often in response to concerns over network operator market power and potential blocking or throttling of content. However, developing countries typically have significantly lower levels of internet penetration and usage. Market power in respect of internet access looks quite different given that mobile is the predominant means of connection and there are often three or more mobile operators. In South Africa, there is a quasi-monopoly in the paid satellite broadcasting market and broadband providers zero-rating content from third parties (such as Netflix) may bring about more competition. We test the main theories of harm arising in the net neutrality debate, including network operator market power and exclusion among content providers using data on the number of announced prefixes and peers and IP addresses and considering examples of bundling and zero-rating conduct by operators. We find that net neutrality rules are less likely to be required in South Africa and other developing countries and that strict enforcement of such rules could in fact hinder competition in markets for content, telecommunications networks and other related markets.  相似文献

Many countries are faced with the problem of monitoring poverty indicators when different food data collection methodologies have been used in national household surveys over the years. This paper provides a comprehensive analysis of this problem in the case of Niger. The paper assesses the impact of three methods of food data collection on the welfare distribution, and poverty and inequality measures in Niger. The study leverages a food consumption experiment to evaluate the three methods of food data collection implemented in the country’s most recent national household surveys. The first method was 7-day recall, the second was usual month, and the third was 7-day diary. The study finds that there was a large difference in measures of consumption and poverty between the first two methods (which yielded similar results) and the 7-day diary method. Annual per capita consumption from the 7-day recall method was, on average, 28 percent higher than that from the 7-day diary method. This gap exists not only at the mean of the distribution, but at every level. The observed differences in measured annual per capita consumption leads to differences in poverty and inequality measures even when alternate poverty lines are used.  相似文献

The paper applies a quantitative methodology to study poverty and livelihood profiles on the basis of a large set of variables. It takes the context of post-conflict rural Rwanda for a case study. By means of exploratory tools (i.e. principal component and cluster analysis), it combines variables that capture natural, physical, human, financial and social resources together with environmental factors to identify household groups with varying livelihoods. The paper further explores how these clusters differ with regards the incidence of poverty, livelihood strategies and their respective crop preferences. The paper concludes that Rwandan rural policies should adopt distinct and appropriate interventions for impoverished peasant groups, each having their own particular livelihood profiles.  相似文献

This study extends prior research by exploring the effects of managerial representations of market and learning orientation on perceived industrial firm capabilities. Cognitions that managers use to make sense of their environment impact competitive strategy decisions. Extant research has found market and learning orientation concepts to be empirically distinct and to have independent and synergistic effects on organizational performance. The present study generally supports hypotheses relating to independent effects of market and learning orientation viewpoints on perceptions of specific capability domains. Findings hold implications for managing the development of organizational capability portfolios as well as for future research aimed at understanding cognitions related to competitive advantage dynamics.  相似文献
