This paper presents comparative qualitative and quantitative evidence from rural Kenya and Madagascar in an attempt to untangle the causality behind persistent poverty. We find striking differences in welfare dynamics depending on whether one uses total income, including stochastic terms and inevitable measurement error, or the predictable, structural component of income based on a household's asset holdings. Our results suggest the existence of multiple dynamic asset and structural income equilibria, consistent with the poverty traps hypothesis. Furthermore, we find supporting evidence of locally increasing returns to assets and of risk management behaviour consistent with poor households' defence of a critical asset threshold through asset smoothing.  相似文献

The moral and economic imperatives to intervene in poverty traps motivate the identification of poverty traps and their structural causes so as to inform the design of appropriate policy responses. However, empirical identification remains challenging because of poverty traps’ complexity. After reviewing mechanisms that can generate poverty traps, we focus on one – multiple financial market failures – emphasising its heretofore underappreciated testable implications, including specific behaviours that are rational only in the presence of a poverty trap. We therefore recommend tests for these behaviours rather than more econometrically challenged efforts to directly test for poverty traps in estimated asset dynamics.  相似文献

The geography of agricultural marketing has important implications for the stochastic distribution of agricultural commodity prices. This article proposes that objective food price risk differs between rural and urban areas of infrastructure‐poor economies characterised by spatially concentrated patterns of foodgrains storage. This difference implies an urban bias having adverse welfare effects for peasants who seasonally switch between net food seller and net food buyer positions. Empirical analysis of rice price data from Madagascar suggests that price variability and skewness indeed differ between rural and urban areas in ways that adversely influence the relative welfare of rural peasants.  相似文献

Asphyxial suicide by placing a plastic bag over the head, especially in combination with inhalation of gases, is a rarely described method of committing suicide. This article reports a case of suicidal asphyxiation by inhaling the inert gas helium inside a plastic bag. A 64-year-old man probably followed the instructions described in an article about committing suicide written by a medical practitioner from Zürich. This form of suicide is recommended by right-to-die groups and in the internet as a certain, fast, and painless suicide method. Additionally, it leaves only seldom externally visible marks or pathomorphological findings on the body. If the plastic bag and other auxiliary means are removed by another person, the forensic death investigation of cause and manner of death may be very difficult. Therefore, the death scene investigation and the inquiry ordered in the environment of the deceased are very important.  相似文献

Collective bargaining, a core social institution, faces a fundamental transformational challenge. National survey data provide unique insights into the current status of the bargaining process — revealing challenges and opportunities. Awareness and use of interest-based bargaining principles is widespread but complicated by underlying tensions between labor and management. The findings illustrate the value of conducting an institutional-level analysis of a negotiations process.  相似文献
