    Aspects of demand-side oriented insurance of volatile food prices in developing and emerging countries
    (2018) Hochscherf, Julian; Schiller, Jörg
    The dissertation is concerned with the relation between formal and informal risk management in developing and emerging countries in the context of rainfall and food price variability. The dissertation contains three research projects. In order to systematize the literature on welfare effects of food price volatility and rainfall risks and the related coping strategies, a systematic review on the quantification of these two risk types has been performed. Many studies in the recent past have been published to quantify poverty effects of materialized risk such as drought events or the consequence of the 2008-09 food price crises in emerging and least developed countries. As agrarian economies in least developed countries heavily depend on the correct onset and amount of rainfall quantities, rainfall failures are likely to have adverse consequences for household income and its volatility. In addition, agrarian households in least developed countries are mostly net food consumers and thus highly dependent on the realization of food prices. The review systematizes the empirical evidence on adverse income effects of drought events and food price increases as well as it summarizes the risk management and coping strategies directly linked to these two shock types. A particular emphasis will be given to the stabilizing power of labor markets and adaptation through consumption responses. The second paper is concerned with informal risk management strategies taken out by agricultural households, in particular with the instrument of labor time allocation. Subsistence farmers in low income countries are confronted with multiple risks. In reaction to them, farm households have developed strategies to cope with yield risks to self-insure against these income shocks. Recent developments in global food markets have increased food price volatility, which, in particular, puts low-income households at risk. When small-scale farmers allocate their labor time over different income generating activities, they face the risk of uncertain purchasing power of income in the presence of food price variability. Thus, the paper analyzes the labor time allocation decision between self-employment and wage labor, taking into account the uncertain purchasing power of wages resulting from food price volatility and the farm production risk induced by rainfall variability. Using a panel structured household data set containing consumer-producer households in rural India, the labor time allocation decision between farming and labor market participation will be analyzed and the effect of production and food price uncertainty on labor time allocation will be estimated. The analysis reveals counterintuitive time allocation effects of risk. The third project is concerned with formal insurance demand by farm households and the interrelatedness between formal and informal risk provision. For this purpose, a data set for a weather index insurance demand product has been analyzed. Index based microinsurance as a tool to insure the income of agriculturally active households has triggered extensive discussions in the literature. Despite the convincing theoretical argumentation, the demand for these products stays behind expectations. Several studies revealed effects impacting the demand for index insurance, such as liquidity constraints, basis risk, lack of understanding and trust in insurers and products alike. This paper takes a different perspective and hypothesizes that low demand is due to heterogeneous risk exposure towards weather variability among potential insured resulting from informal risk management. The paper tests the impact of income heterogeneity as a measure of risk exposure on insurance demand and finds that risk exposure negatively affects insurance demand. In order to increase demand, it is concluded that product design should emphasize more the importance of income risk composition and exposure of potentially insured. The dissertation concludes with a critical discussion of how to reconcile formal and informal risk management practices and gives policy implications of how to innovate existing formal insurance products to increase demand.

    Vulnerability and risk management of rural farm households in Northern Vietnam
    (2010) Fischer, Isabel; Heidhues, Franz
    Despite the achievements of the ?doi moi? reform process, which was launched in 1986, Vietnam is still one of the poorest countries in the world, with 28.9 per cent of the total population (85 million in 2007) living below the national poverty line (UNDP 2007). Especially the mountainous, rural areas of Northern Vietnam are underdeveloped. Poor and near-poor farm households endure manifold risks and income shocks, which threaten their existence. Normally, insurance systems would step in to assist. In developing countries however, where access to formal insurance services is hardly available, rural farm households have developed alternative risk management strategies. The Sustainable Livelihood Framework (SLF) of the Department for International Development (DFID 1999), was applied as an analytical tool to identify and assess risks and risk management strategies of vulnerable rural livelihoods in the Uplands of Northern Vietnam. The role of informal social networks was analyzed with the help of Social Network Analysis (SNA). An Adaptative Conjoint Analysis (ACA) was implemented to examine the potential demand for a formal or semi-formal microinsurance scheme in the area of livestock insurance. Furthermore, additional insights were gained from interdisciplinary research on issues of human, health and livelihood security, as well as from case studies on natural resource use in Southeast Asia. The central hypotheses of this research on livelihood strategies in general and adaptive strategies such as insurance in particular are that they (1) have the potential to reduce livelihood vulnerability and that (2) the differentiated knowledge of livelihood strategies is crucial for a better understanding of the reasoning behind the exploitation of livelihood assets, such as natural resources or physical assets in the form of livestock, despite the negative medium and long-term effects. Research results lead to the following conclusions: First of all, only a very elaborate use of existing capital assets can improve the livelihood situation of vulnerable households in Northern Vietnam. Living in remote mountainous regions with scarce natural resources and limited access to other assets, the preconditions are rather difficult for ethnic minority people, even more for women. Secondly, in order to improve the situation, all stakeholders have to be aware of the existing risk management strategies (e.g. raising livestock and selling it in case of a livelihood emergency is one of the most popular risk coping strategies in the mountainous regions of Northern Vietnam) and learn from both, advantages and disadvantages of currently applied strategies to translate them into effective policies. Concerning the access to financial services, people still face several constraints, as credits are often not available for certain activities or at a certain point in time. In addition, savings and insurance services, when available are not adapted to the needs. Furthermore, emerging expenditures for livelihood risks usually go beyond the scope of the dis-saving (in cash and in kind) ability of rural households. Taking into consideration the above stated situation of changing agricultural activities, including higher input use, and the resulting decline in the number of large ruminants, one should be very careful not to destroy the so far still functioning traditional social networks. Even though these networks are not able to fully buffer all shocks and crises, they are at least one asset (social capital asset) that is initially accessible by everybody and quite often a means to compensate to some degree the lack of other capital assets as depicted in the SLF. Research results point to a number of policy issues that need to be addressed if household?s vulnerability to poverty is to be significantly reduced among ethnic minority households in Northern Vietnam. First of all, poverty reduction strategies and programs need to consider a broader target group, not only the currently poor but also the vulnerable households. The promotion of innovative financial products, such as a combination of credit and insurance, especially for loans that are taken up to purchase livestock, is considered a successful approach to support vulnerable households. Finally, it is assumed that an efficient and accessible health care system would be an important alternative for securing livelihoods. In addition, im¬pro¬ved extension services and knowledge transfer for all people, especially women, could sup¬port a sustainable future development of ethnic minority households and therefore, in the long-run, lead to poverty alleviation.
