| 内容記述 | There is a large volume of empirical literature on risk coping and consumption smoothing in the context of rural areas of developing countries where people’s livelihood is always threatened by various risks. “Coping” implies the process of recovery from a shock. However, the existing literature does not consider time required for households and/or individuals to recover the level of consumption. Shortcomings of such analyses are that welfare impact of a shock can be underestimated because they cannot separate the shocks (i.e. reduction of consumption) and the recovery (i.e. increase of consumption) if recovery process starts before ex post data collection. In order to improve the existing literature, this paper incorporates time dimension in the process of recovery from a shock. For this purpose, this paper adapts the concept of resilience from ecology and defines it in the context of consumption smoothing. Moreover, unlike most of previous studies on consumption smoothing, this paper utilizes weekly data collected before and after the happening of a covariate shock so as to provide empirical evidence of resilience. This paper firstly provides an empirically-workable definition of “resilience” at household as well as individual levels. At the household level, resilience is based on the measurement of household food consumption per capita and is defined by the speed of the recovery of food consumption from a shock. At individual level, on the other hand, body weight is used for the measurement of resilience and the speed of the recovery of body weight from a shock is the definition of resilience. Then, this paper demonstrates how to measure resilience using our own survey data collected in the Southern Province of Zambia, the most drought-prone zone in the country. Just after we started data collection in the field, unusual heavy rain took place in December 2007. Since the heavy rain damaged crops in the field and destroyed infrastructure such as road and bridge, we considered that it should have caused a shock to households and individuals in the study site. The analyses compare two sites: Site A and Site B. Normally Site A receives fewer rain and more susceptive to drought than Site B. But the heavy rain in December 2007 occurred in both sites almost equally. Nevertheless, only in Site A significant reduction of food consumption per capita and body weight was observed, and it took several months for both indicators to return to the original level. By definition, households and individuals in Site A are less resilient that those in Site B. |
