发展中国家的家庭经常受到严重特质和协变量冲击的袭击，导致消耗量高。因此，一个家庭目前观察到的贫困状况可能不是家庭普遍遭受贫困的良好指标。近年来，关于脆弱性的概念和经验分析，已经有了新兴的文献。但是，由于对发展中国家的脆弱性分析和面板的可用性有限的可用性有限的数据要求，静态贫困分析仍然占主导地位的经验脆弱性研究。在本文中，我们提出了一种简单的方法，可以从经验上评估特质和协变量冲击对家庭脆弱性的影响，这可以在广泛的环境中应用，因为它依赖于更常见的横截面或短面板数据。我们从经验上说明了马达加斯加的方法。我们表明，协变量冲击对农村家庭的影响相对较高，而特质冲击对城市家庭脆弱性的影响相对较高。 （c）2008 Elsevier Ltd.保留所有权利。
Households in developing countries are frequently hit by severe idiosyncratic and covariate shocks leading to high consumption volatility. A household's currently observed poverty status might therefore not be a good indicator of the household's general vulnerability to poverty. In the recent years, there has been an emerging literature on the concept and empirical analysis of vulnerability. But because of strong data requirements for vulnerability analysis and limited availability of panel and shock data for developing countries, static poverty analysis still dominates empirical vulnerability studies. In this paper, we propose a simple method to empirically assess the impact of idiosyncratic and covariate shocks on households' vulnerability, which can be applied in a wide context as it relies on more commonly available cross-sectional or short panel data. We empirically illustrate our approach for Madagascar. We show that covariate shocks have a relatively higher impact on rural households, whereas idiosyncratic shocks have a relatively higher impact on urban households' vulnerability.
