Empirical evidence on the role of cattle sharing and rental contracts in agrarian economies is limited. This article is an investigation of different types of cattle sharing and rental contracts producers in rural Ethiopia adopt. It also investigates why households in rural Ethiopia rely on these contracts that are vulnerable and therefore subject to potential moral hazard problems described in earlier literature. We apply random effect probit and control function econometric methods to household panel data collected in 2005 and 2007 from two agro‐ecological zones in Ethiopia. Controlling for the endogeneity of access to livestock credit, we find that contracts are spatially fragmented and better developed where population density is high and credit and insurance markets are poorly developed. We also find that contracts help cash poor and credit constrained households to improve their herd dynamics, to get access to nonlivestock resources (land, labor and cash) and share risks that could have been difficult without the contract. We show that contracts are rational responses of residents in rural communities characterized by imperfect credit and insurance services, since households with better access to credit are less likely to rely on contracts. 相似文献

This article examines factors related to a livestock rental market in western Nepal and assesses whether this market is associated with caste differentiation and land rental market participation. Theoretical models for asset‐rich (i.e., high‐caste) households, rich in land and livestock, and asset‐poor (i.e., low‐caste families) households are presented to provide logical explanations for the existence of a livestock rental market and the synergy between livestock and land rental markets participation. A combination of double hurdle models and bivariate‐ordered probit models were used to test the implications of the models. Consistent with the theoretical models, land‐ and livestock‐rich high‐caste households were more likely to rent out land and/or livestock, whereas land‐ and livestock‐poor and credit constrained low‐caste households were more likely to rent livestock and land from others. Participation in the two markets was positively correlated, indicating a synergistic relationship that may be due to production and transaction costs reducing benefits. Policies that can enhance the allocative efficiency of livestock and land rental markets can improve equity as well as efficiency of land use in Nepal. Provision of livestock credit to land‐poor low‐caste households is also crucially dependent on their access to more long‐term contracts for land. 相似文献

Unanticipated events can cause considerable economic hardship for poor rural households. Some types of negative shocks, for example weather‐related agricultural losses and vector‐borne diseases, are expected to occur more frequently as a result of climate change. In this paper we measure the role of household‐ and location‐specific characteristics in conditioning behavioural responses to a wide range of idiosyncratic and covariate shocks. We use data from 8,000 rural households in 25 developing countries, compiled in the global database of the Poverty Environment Network. We employ a hierarchical multinomial logit model to identify the importance of characteristics observed at different levels of aggregation on a set of strategies aimed at coping with economic shocks. Results indicate that in response to idiosyncratic shocks, households tend to deplete financial and durable assets, whereas covariate and thus often climate‐related shocks predominantly result in reduced consumption. Households in sites characterised by high asset wealth tend to cope with shocks in a more proactive way than those in sites with average or below average asset wealth, but the role of asset types in conditioning shock responses varies across regions. Our findings have implications for rural development and climate change adaptation strategies. 相似文献

Canola has become an important crop in the last decade in the United States. Production of canola is risky and competes with other crops that have varying risk reduction mechanisms. Processors develop and offer contracts with varying specifications that allow growers to reduce risk and attract canola production. In this study, preplant contracting strategies were evaluated in terms of risk and return for growers and processors. Alternative contracts include fixed‐price‐variety‐specific with and without act‐of‐God provisions, and an oil‐premium contract. Grower returns and processor gross margins were simulated and resulting distributions were evaluated using stochastic efficiency with respect to a function. In the dominant growing region, growers would prefer fixed‐price‐variety‐specific contracts versus contracts with oil premiums. The latter would only be preferred by crushers that are highly risk averse. The results vary regionally suggesting that contract types should vary by region to be acceptable to a broader range of growers and processors. 相似文献

Most evaluations of payments for environmental services programs focus on immediate environmental impacts, and do not measure the effects on socioeconomic outcomes or on other land use activities (leakage). Efficient allocation of land use contracts, through auctions for example, may help mitigate concerns about adverse livelihood or leakage effects. This study reports on a field experiment that varied the allocation of afforestation contracts to smallholder farmers in Malawi. Households were randomly assigned to participate in an auction or in a lottery for the contracts, which provided three years of payment based on tree survival outcomes. Households that did not receive a contract as a result of the lottery form a pure comparison group. The results show evidence for within-farm leakage for households that received a contract at random, in the form of additional land clearing. Randomly contracted households are also more likely to report household labor shortages. These effects are mitigated to some degree when contracts are assigned through an auction. Together, the results point to leakage and livelihood impacts from payments for environmental services that are often overlooked in standard evaluations, but which may be reduced through improvements in contract targeting. 相似文献

This paper analyses the role of risk and rate of time preference in the choice of land contracts. The analysis builds on the risk‐sharing and imperfect market explanations of contract choice. Unique data from Ethiopia, which contain land contract information and experimental risk and rate of time preference measures on matched landlord–tenant partners, are employed in the empirical analysis. The results show that landlord and tenant time preferences are significant determinants of contract choice. For landlords (but not tenants), risk preference is also significant, indicating the importance of financial constraints and production risk in the determination of contract choice. The results are of particular relevance to land market policy in Ethiopia, where production is risk‐prone, financial markets are imperfect, and where there is a major need for the development of vibrant land rental markets. 相似文献

In this paper, we assess the long‐term effect of floods on food security (as measured by calorie and micronutrient consumption) by applying an instrumental variable approach to data from the Afghanistan National Risk and Vulnerability Assessment survey. To identify the determinants of this effect, we also estimate how floods affect per capita yearly household income and poverty status. We find that exposure to flooding during a 12‐month period decreased daily calorie consumption by approximately 60 kcal while increasing the probability of iron, vitamin A, and vitamin C deficiency by 11, 12, and 27 percentage points, respectively. Controlling for price shocks and income only marginally reduces this flood effect on food security, suggesting that impaired livelihoods (rather than price hikes) are its primary driver. We further determine that exposure to this natural disaster decreases income by about 3% and makes flood‐affected households about 3 percentage points more likely to be poor. Lastly, we show that experience of floods is strongly and significantly associated with lower diet quality and quantity, and with engaging in consumption smoothing coping strategies, such as buying food on credit and taking loans. These findings underscore the serious direct impact of floods on both diet and effective behavioral responses to such shocks while emphasizing the need for targeted micronutrient supplementation in disaster relief and food aid measures even after the period of natural disaster emergency. 相似文献

Using data from NLSS III, we estimate nutrient‐income elasticities for macronutrients, vitamins, and minerals. We further allow for differential nutrient demand response to income depending on where a household is in the caloric availability distribution. We find that some nutrients are income inelastic indicating that they are necessity goods while others are relatively income elastic. We further test and reject equivalent nutrient‐income elasticities across the caloric availability distribution. Households in the lowest calorie quintile have highly income elastic nutrient demand leaving them vulnerable to income fluctuations. Moreover, as households meet their first‐order caloric needs, they substitute away from cheap calorie‐dense staples toward more expensive nutrient‐dense foods. Finally, for most nutrients, households in the highest calorie quintile exhibit more elastic nutrient demand, similar to households in the lowest quintile. Our results suggest that policies aimed at improving income will likely also improve household nutrient availability, particularly for the most calorie poor households. They further suggest that policies aimed at protecting poor households from negative income shocks will also likely yield nutritional benefits. 相似文献

In emerging markets for high‐value food products in developing countries, processing companies search for efficient ways to source raw material of high quality. One widely embraced approach is contract farming. But relatively little is known about the appropriate design of financial incentives in a small farm context. We use the example of the Vietnamese dairy sector to analyze the effectiveness of existing contracts between a processor and smallholder farmers in terms of incentivizing the production of high quality milk. A framed field experiment is conducted to evaluate the impact of two incentive instruments, a price penalty for low quality and a bonus for consistent high quality milk, on farmers’ investment in quality‐improving inputs. Statistical analysis suggests that the penalty drives farmers into higher input use, resulting in better output quality. The bonus payment generates even higher quality milk. We also find that input choice levels depend on farmers’ socio‐economic characteristics such as wealth, while individual risk preferences seem to be less important. Implications for the design of contracts with smallholders are discussed. 相似文献

Perennial energy crops are a promising source of bioenergy whose production involves production risks, long‐term commitment of land and need for crop‐specific investments without the coverage of crop insurance potentially available for conventional crops. We conduct a choice experiment in five states in the Midwestern and South‐central regions of the U.S. to examine the effect of crop‐contract attributes on the joint discrete‐continuous choice decisions to adopt an energy crop and convert acres to it from a status quo use, while controlling for the effect of various farmers’ risk and time preferences, sociodemographic characteristics, and availability of crop insurance for conventional crops. We find robust evidence that high discount rates, high upfront establishment costs and need for crop‐specific investments create disincentives for adoption and allocation of land to energy crop production. The effects of riskiness of returns and risk aversion are less robust across specifications. The effect of conventional crop insurance on the energy crop adoption decision differs across types of insurance; in particular, farmers with revenue insurance are statistically significantly less likely to adopt an energy crop. Our results have implications for the design of effective contracts and policy incentives to induce the production of energy crops. 相似文献

Sub‐Saharan Africa (SSA) is one of the regions in the world most affected by food price volatility and production variability. Poor small‐scale farmers in this region are particularly vulnerable to this variability. As a result, households may be reluctant to adopt new agricultural water management (AWM) technologies when they involve more risk than what they mitigate. Despite risk's role in AWM investments, there have been few attempts to estimate the magnitude and nature of risk aversion in relation to this type of farm decisions. To partially close this gap, this article uses an experimental approach applied to 137 households in Northern Ghana. We find that more than 70% of households are moderately or slightly risk averse. This contrasts with other studies in SSA, where most household decision‐makers exhibit severe to extreme risk aversion. We also find that households that stand to lose as well as gain something from participation in games are less risk averse than households playing gains‐only games. This result suggests that most farmers’ current wealth put them at risk of falling into a poverty trap. Thus, the losses from the riskiest investments on AWM technologies may fall more heavily on the poor, suggesting that additional efforts be given to the creation of viable insurance mechanisms. 相似文献

This article contributes to a growing body of empirical literature relating credit constraints and incomplete insurance to investment decisions. We use panel data from rural Ethiopia to investigate whether participation in a safety net program enhances fertilizer adoption. Using a difference‐in‐differences estimator and inverse propensity score weighting, we find that participation in Ethiopia's food‐for‐work (FFW) program increased fertilizer adoption in the short run, but not in the long run. Results also indicate that the intensity of fertilizer usage increased with livestock holdings for FFW‐participant households, providing some evidence that the intervention helped asset‐rich farm households more than asset‐poor households. We find no significant effects of free distribution on fertilizer adoption or intensification. Our results are consistent with the hypothesis that safety nets can be viewed as mechanisms that allow households to take on more risk to pursue higher profits. The results highlight the importance of safety net programs, their effectiveness in ensuring farmers that they will be protected against uninsured shocks, and how that assurance can translate into productivity‐enhancing behavior. 相似文献

Lack of access to credit prevents poor households in developing countries from diversifying into income‐generating activities that could safeguard them against unforeseen shocks and seasonality, leaving them susceptible to food deprivation, even when aggregate food supplies are adequate. Microcredit programmes help these households to access financial capital that could help improve their food security situation. We examine how microcredit affects different measures of food security; namely, household calorie availability, dietary diversity indicators and anthropometric status of women of reproductive age (15–49 years) and children under the age of 5 years. We find that microcredit programme participation increases calorie availability both at the intensive and extensive margins, but does not improve dietary diversity and only has mixed effects on the anthropometric measures. We also find that the effect of microcredit participation on food security may be non‐linear in which participation initially has either no effect on food security or may actually worsen it, before improving it in the longer run. Our results help to explain why existing short‐term evaluations of microcredit sometimes do not show any positive effects. 相似文献

Policy instruments for sustainable land management: the case of highland smallholders in Ethiopia 总被引:6,自引:0,他引:6
Degradation of land continues to pose a threat to future food production potential in many developing economies. Various approaches, mainly based on command‐and‐control policies, have been tried (with limited success) in the past to encourage adoption of erosion‐control practices by farm households. High transactions costs and negative distributional impacts on the welfare of the poor limit the usefulness of standards and taxes for soil and water conservation. One innovative approach is the use of interlinked contracts which create positive incentives for land conservation. This study analyses the social efficiency of such policies for erosion‐control in the Ethiopian highlands using a non‐separable farm household model. Incentive contracts linked with conservation seem to be promising approaches for sustainable resource use in poor rural economies. This may suggest that conservation programs should give greater consideration to better fine‐tuning and mix of policies that help achieve both economic and environmental objectives. 相似文献

This paper focuses on the vulnerability of rural households to poverty when a negative crop shock occurs. The analysis is based on the ICRISAT panel survey of households in a semi‐arid region in south India during 1975–84. Using a dynamic panel data model that takes into account effects of crop shocks, an assessment of vulnerability of different groups of households is carried out. What is somewhat surprising is that even sections of relatively affluent households are highly vulnerable to long spells of poverty when severe crop shocks occur. As such crop shocks are frequent in a harsh production environment, there must be a shift of emphasis in anti‐poverty measures from meeting income shortfalls among the poor to enabling the vulnerable to protect themselves better against these shocks. 相似文献

Despite several studies showing the effect of access to markets and weather conditions on crop production, we know quite little on whether and how livestock production systems respond to variation in weather risk and access to markets. In this paper, we study whether and how livestock production responds to (access to) markets and varying weather risk. We also explore whether such responses vary across livelihood zones and livestock production systems. We study these research questions using households’ livestock production, ownership, and marketing decisions of households in Ethiopia. We find that households living close to markets are more likely to engage in market-oriented livestock production and use modern livestock inputs. We also find that households exposed to more unpredictable weather are less likely to engage in livestock production for markets, rather they are more likely to engage in livestock production for precautionary savings and insurance. Furthermore, greater rainfall uncertainty influences livestock portfolio allocation toward those which can be easily liquidated while also discouraging investment in modern livestock inputs. However, these responses and patterns vary across livelihood zones and production systems; most of these stylized responses and impacts are more pronounced and significant in the arid and semi-arid lands of Ethiopia, where livestock herding remains a dominant source of livelihood. Those households relying only on livestock production seem more sensitive and responsive to weather risk and weather shocks. The heterogeneity in responses and impacts of weather risk among farming systems and livelihoods highlights the need for more tailored livestock sector policies and interventions. 相似文献

A complete demand system for Vietnam was estimated using household survey data. Results showed that demand for rice with respect to prices and expenditure is relatively inelastic compared to other foods. Demand for food in general tends to be less elastic at higher levels of income and for urban households. In the short term, a market shock such as a 10% decrease in income or a 30% increase in rice prices forces households to spend a larger portion of their expenditure on rice at the expense of other foods. Low‐income households face a higher risk of undernourishment as their daily calorie intake is more negatively affected by the shocks than high‐income households. The results suggest the importance of policies that provide necessary safety net programs for the poor. 相似文献

This article examines a self-enforcing contract between a risk-neutralprincipal and a risk-averse agent who is able to hold up valuesex post. It shows that risk aversion and variance can only partlyexplain the contract's incentive intensity. Ex post bargainingpower and outside options will also determine contract choice.If the agent's ex post bargaining position is weak, the principalcannot commit to high-powered incentives, whereas if the agent'sex post bargaining position is good, the agent cannot committo low-powered incentives. The model may thus explain some puzzlesin agricultural contracts, in particular why risk-averse agentssometimes accept to be governed by high-powered incentive contractsthat are quite similar to fixed rental contracts, and why risk-neutralagents are sometimes offered share contracts with lower-poweredincentives. 相似文献

In Washington State, small forest landowners (SFLO) play an important role in maintaining forest cover on the landscape as well as associated ecosystem services. This paper examines landowner preferences for the attributes of working forest conservation contracts (WFCC) using a choice experiment. The attributes examined are contract duration (from 10 years to perpetuity), forest management requirements, and the extent of forestland covered under the contract. We find that contract attributes are valued very differently depending on landowner objectives and harvesting behavior. Landowner characteristics and forestland spatial characteristics including distances to development and large public forestlands were found to significantly influence the likelihood of contract acceptance. While a significant portion of preference heterogeneity remains unobserved, we identify several key sources of landowner preference heterogeneity which allows for a better understanding of which landowners are likely to enroll in voluntary forest conservation contracts and may have implications for improved targeting of contracts. 相似文献
