DIW Wochenbericht 11 / 2020
Weltweit steigt die Anzahl überschuldeter Privathaushalte. Die möglichen Gründe für diesen Anstieg sind nicht hinreichend erforscht. Der vorliegende Bericht verdeutlicht, dass überhöhte Einkommenserwartungen, die durch unsichere Einkommensverhältnisse befördert werden, zu überoptimistischen Konsumentscheidungen und verstärkter Kreditaufnahme führen können. In einer Umgebung ohne starke Regulierung, ...

Entrepreneurs tend to be risk tolerant but is more risk tolerance always better? In a sample of about 2,100 small businesses, we find an inverted U-shaped relation between risk tolerance and profitability. This relationship holds in a simple bilateral regression and also when we control for a large set of individual and business characteristics. Apparently, one major transmission goes from risk tolerance ...

Diskussionspapiere 1996 / 2022
A number of studies show that there is a link between social comparison and high levels of household debt. However, the exact mechanisms behind this link are not yet well understood. In this paper, we disentangle two mechanisms by performing a lab experiment designed to study the effects of social image concerns and peer information on consumption choices financed through debt taking. We find that ...

This study tests the prediction that perceived corruption reduces ethical behavior. Integrating a standard “cheating” experiment into a broad household survey in rural Thailand, we find clear support for this prediction: respondents who perceive corruption in state affairs are more likely to cheat and, thus, to fortify the negative consequences of corruption. Interestingly, there is a small group of ...

This study tests the prediction that a corrupt government reduces ethical behavior among its citizens. We integrate a standard "cheating" experiment into a broad household survey and find clear support for this prediction: respondents who perceive corruption in state affairs are more likely to cheat. Interestingly, there is a small group of non-conformers. The main relation is robust to consideration ...

DIW Roundup 130 / 2019
Although households in developing and emerging countries are relatively poor, there is potential to save. For example, one study estimates that up to 8.1% of a poor household’s budget in such countries is spent on so-called temptation goods, like alcohol, tobacco, and festivals (Banerjee and Duflo, 2007). At the same time, many households are aware of the fact that they do not save enough. They name ...

This study tests the prediction that perceived corruption reduces ethical behavior. Integrating a standard “cheating” experiment into a broad household survey in rural Thailand, we find tentative support for this prediction: respondents who perceive corruption in state affairs are more likely to cheat and, thus, to fortify the negative consequences of corruption. Interestingly, there is a small group ...

We develop and implement a new measure for inequality aversion: two peers are endowed with identical binary lotteries and the only choice they make is whether they want to play out the lotteries independently or with perfect positive correlation (coupling). Coupling has the core reason to prevent outcome inequality. We implement the method in a survey in rural Thailand as well as in a supplemental ...

Household indebtedness is rising worldwide. This study investigates one possible driver of this increase that is rooted in the theory of permanent income: high income expectations. We collect data from an emerging country, Thailand, as (over-) indebtedness in markets with incomplete financial infrastructure and social security can be devastating. Furthermore, our sample of rural households is exposed ...
