There is growing interest in understanding the links between land reforms, land markets, and poverty reduction in Africa. The study uses four‐wave panel data from the northern highlands of Ethiopia to assess the dynamics of rural poverty taking into account the status of participation of rural households in the land rental market. Applying both nonparametric (Kaplan–Meier estimator) and semi‐parametric survival models that control for duration dependence of poverty transition, results show participation and degree of participation on the supply side of the tenancy market (landlords) have highly significant and positive effect on the chances of escaping poverty while the same cannot be said about the demand side of the tenancy market (tenants). The empirical evidence also confirms that households headed by older and literate people have relatively larger exit rates from poverty as compared with households headed by younger and illiterate ones. Though transacting farmers may engage themselves in win–win rental arrangements by the time they join the tenancy market, results indicate that gains are unequal as those tenants who enter the markets from low economic leverage (were poor) are liable to face a lower margin of net gains, which may limit their ability to move out of poverty. 相似文献

What are the long-term effects of universal preschool programs on child outcomes? We review 26 studies using natural experiments to estimate the effects of universal preschool programs for children aged 0–6 years on child outcomes measured from third grade to adulthood. Studies comparing universal preschool with a mix of parental, family, and private modes of care show mixed effects on test scores and on measures related to health, well-being, and behavior. All estimates for outcomes related to adequate primary and secondary school progression, years of schooling, highest degree completed, employment, and earnings indicate beneficial average effects of universal preschool programs. Three of the included studies calculate benefits-to-costs ratios and find ratios clearly above one. Universal preschool tends to be more beneficial for children with low socioeconomic status and there are not consistently different effects for boys or girls. Only three studies compare two alternative types of universal preschool programs in terms of long-term outcomes. 相似文献

Drought tolerant (DT) maize varieties have received massive support in sub‐Saharan Africa because of their potential to protect smallholder farmers against drought‐related maize yield losses. Using four waves of household farm panel data from six districts in Malawi, we examine the impact heterogeneity of this technology on maize productivity using a continuous treatment approach. We find strong evidence of positive correlation between maize yield and adoption of DT maize varieties. On average, an increase by one hectare in the area allocated to DT varieties increases maize yield by 547 Kg/ha representing a 44% increase from the average maize yield of 1,254 Kg/ha for our sample. Our findings give evidence that DT maize technology has potential to protect smallholder farmers against drought‐related production losses. Policies that promote increased allocation of maize area to DT maize hold potential to enhance food security. Smallholder farmers especially in drought‐prone areas should be encouraged to allocate at least one‐third of the maize plot to DT varieties while breeders continue with the efforts of breeding a DT variety that is not only drought tolerant but also adapted to all weather conditions. More importantly, the government should ensure provision of timely ex ante weather information to guide farmers on decision‐making with respect to maize varietal choices. 相似文献

We develop a model that clarifies the respective advantages and disadvantages of academic and private‐sector research. Rather than relying on lack of appropriability or spillovers to generate a rationale for academic research, we emphasize control‐rights considerations, and argue that the fundamental tradeoff between academia and the private sector is one of creative control versus focus. By serving as a precommitment mechanism that allows scientists to freely pursue their own interests, academia can be indispensable for early‐stage research. At the same time, the private sector's ability to direct scientists toward higher‐payoff activities makes it more attractive for later‐stage research. 相似文献

This paper presents a short narrative example intended for use in teaching the Austrian Business Cycle Theory, meant to complement theoretical presentations by presenting an idealized account of an individual entrepreneur operating over time and responding to various possible evolutions of the interest rate. In particular, the similarity from the point of view of the entrepreneur between a reduction in the interest rate due to an increase in consumer saving and a similar reduction due to monetary policy is emphasized. Along with the narrative itself, we discuss the motivating version of the Austrian Business Cycle behind the narrative, as well as offer commentary as explanation for the particular choices made in its construction. 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

Die Finanz- und Wirtschaftskrise hat sich seit 2008 entfaltet. Seitdem gibt es verschiedene Versuche, ihre Folgen durch Rettungsschirme,
Konjunkturprogramme und gesetzliche Regelungen in den Griff zu bekommen. Immer dringender stellt sich auch angesichts des
jüngst vorgestellten Sparprogramms der Bundesregierung die Frage, wer tats?chlich von diesen Ma?nahmen profi tiert, wer sie
bezahlen muss und ob die Verursacher der Krise angemessen an den Kosten der Schadensregulierung beteiligt werden. 相似文献

Food-for-work (FFW) is the most widely used type of public works program in Ethiopia through which a high share of the food aid is distributed. This paper assesses the impacts of FFW in Tigray, a chronically food insecure region in Ethiopia, in terms of relieving liquidity constraints and thereby improving input use in agriculture. A Heckman selection model on the adoption and intensity of fertilizer use demonstrated that FFW positively influenced the decision to adopt fertilizer and there was no evidence of disincentive effect. 相似文献
