TitelPoverty dynamics and sustainable development: A long term panel project in Thailand and Vietnam
Thailand Vietnam Socio Economic Panel (TVSEP)
ForschungszieleThe objective of this project is to extend the panel household surveys in Thailand and Vietnam for another 9 years (6 waves of rural household and two waves for migrant surveys) to generate a much deeper understanding of income and poverty dynamics in rural areas of rapidly changing emerging economies. This will be achieved by providing high-quality data and making them accessible to an international community of researchers, and by pursuing aspects of this research agenda as part of this project. By facilitating data access and providing advice the project will promote significant advances in research in development and agricultural economics by high-profile research groups worldwide.
MethodologieContinued panel surveys of village and household level, in addition: migrant tracking surveys;
National Research Data Collection Centers will be set up in the two countries, in Thailand and Vietnam;
A central database of the project will be created.

TitelIndividual risk attitudes in rural Thailand and Vietnam
ForschungszieleThis project aims for generating a better understanding of the role of individual risk attitude in explaining economic behaviour of poor households as a pre-requisite for empirical research to build up a considerable database serving the specific needs of research.
The project has four objectives, namely: (1) to validate various measures of individual risk attitude in the cross-section, (2) to generate understanding about the determinants of risk attitude in the time-series, (3) to analyze the influence of financial literacy, and (4) to analyze the role of risk attitude of agricultural decision makers together with their past experience and their level of knowledge on management decisions in agriculture.
MethodologieA representative household survey in rural areas of Thailand and Vietnam will be conducted.
The resulting database provides comprehensive information about characteristics of these households, including about all kinds of shocks and risks and the respondent individual risk attitudes.

TitelLong-term effects of risk and time preferences on households’ welfare in emerging market economies
Forschungsziele

Economic theory suggests that risk aversion and time discounting should decline in wealth. As a conclusion, poorer households, especially in developing countries, are considered to be more risk averse and more impatient than wealthier households, which in turn lead the poorer to take management decisions that could perpetuate their lives in poverty. However, our understanding of the complex and dynamic interactions between risk and time preferences, risk management and poverty, especially in different dimensions of well-being, is still quite limited, because of data limitations and highly compartmentalized research methods.

This research project applies a holistic approach, where the dynamic interrelations between risk and time preferences, risk management and the multiple dimensions of poverty will be disentangled in order to derive longer-term prospects for sustainable development of rural households in transition economies.

The emerging market economy of Thailand, which has seen a considerable decline in poverty but remains strongly vulnerable to adverse risks, is a suitable stage to effectively investigate the dynamic interactions between preferences, risk management and poverty.

The research project investigates these interactions by differentiating between two levels of risk management strategies, i.e. (i) risk management at the individual level such as diversifying income sources, and (ii) risk management at the group level such as sharing risks with other households in social networks. Drivers and impacts of risk management strategies at both levels are the objects of investigation. The investigation of drivers of risk management decisions will go beyond standard economic theory and incorporate alternative theories such as prospect theory and quasi-hyperbolic discounting. Among the impacts of risk management strategies, both monetary indicators and non-monetary indicators of well-being will be taken into account.

MethodologieThe empirical foundations for the research are built upon the existing long-term panel data set of approximately 2000 households from rural Thailand over 5 waves from 2007 to 2013 collected within the scope of the DFG-FOR 756 project. In the proposed research the existing data base will be complemented by economic field experiments to elicit risk and time preferences and by collecting information on households’ social networks. With the extended long-term panel database our understanding of the dynamic interlinkages between risk and time preferences, risk management and multidimensional poverty can be significantly improved.

TitelInsurance and Private Transfers – Experimental Evidence
ForschungszieleMost people in developing countries are currently not insured; they therefore depend on private transfers from relatives and friends when hit by a shock. However, the provision of insurance is steadily increasing. An important question is to what extent the possibility to purchase insurance affects the willingness to help others. Previous research shows contradicting effects: some studies find a decrease in private transfers, others an increase. The underlying drivers remain unclear. Guided by the literature on other-regarding preferences, the proposed project investigates potential mechanisms that may help explain changes in helping behavior.
MethodologieWe analyze these mechanisms in a framed field experiment combined with a household survey on transfer behavior within social networks. We conduct the project in several villages in Cambodia.

TitelCost-benefit analysis of sustainability standards in small holder oil palm farming in Sumatra, Indonesia
ForschungszieleThis research aims to assess the acceptance and economic consequences of standards for sustainable oil palm farming among small holders in the province of Jambi, Sumatra, Indonesia.
This study will draw from an existing panel data set of some 291 small holder oil palm farmers from 2010 and 2012 in two districts of Jambi.
Three hypotheses will be tested:
(1) smallholder oil palm farmers are aware of the environmental standards promoted by the Government in oil palm plantations;
(2) the benefits of sustainable oil palm management practices are uncertain;
(3) woman can play a major role in implementing sustainable oil palm management practices.
Fieldwork to test the first hypotheses has already been conducted during July - August 2012.
For 2013, additional data collection is proposed with the objective to test the second and the third hypotheses. Individual interviews, focus group discussions with village groups and a stakeholder workshop will be conducted to establish the empirical base for developing and applying cost benefit analysis.
