- We investigate risk and ambiguity attitudes among Ethiopian farmers in one of the poorest regions of the world. Strong risk aversion and ambiguity aversion were found with the Ethiopian farmers. We compared their attitudes to those of a Western university student sample elicited by the same decision task. Ambiguity aversion was similar for farmers and students, but farmers were more risk averse. Our results show that ambiguity aversion is not restricted to Western student populations, and that studies of agricultural decisions may benefit from explicitly considering ambiguity attitudes.

Back To Bentham: Should We? Large‐Scale Comparison of Decision versus Experienced Utility for Income‐Leisure Preferences
- 2015
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Subjective well‐being (SWB) is increasingly used as a way to measure individual well‐being. Interpreted as "experienced utility", it has been compared to "decision utility" using specific experiments (Kahneman et al., 1997) or stated preferences (Benjamin et al. 2012). We suggest here an original large‐scale comparison between ordinal preferences elicited from SWB data and those inferred from actual choices (revealed preferences). Precisely, we focus on income‐leisure preferences, closely associated to redistributive policies. We compare indifference curves consistent with income‐leisure subjective satisfaction with those derived from actual labor supply choices, on the same panel of British households. Results show striking similarities between these measures on average, reflecting that overall, people’s decision are not inconsistent with SWB maximization. Yet, the shape of individual preferences differ across approaches when looking at specific subpopulations. We investigate these differences and test for potential explanatory channels, particularly the roles of constraints and of individual "errors" related to aspirations, expectations or focusing illusion. We draw implications of our results for welfare analysis and policy evaluation.

Cooperation and punishment: The effect of religiosity and religious festival
- 2015
-
Ingår i: Economics Letters. - : Elsevier BV. - 0165-1765. ; 130, s. 43-46
-
Tidskriftsartikel (refereegranskat)abstract
- This paper examines how a religious festival (Ramadan) and the degree of religiosity affect cooperation and costly punishment in a public goods experiment. We find significantly higher cooperation levels outside the festival among less religious people. This behavior is consistent with a substitution effect between religious and non-religious activities. © 2015 Elsevier B.V.

Does relative income matter for the very poor? - Evidence from rural Ethiopia
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- We studied whether relative income has an impact on subjective well-being among extremely poor people. Contrary to the findings in developed countries, we cannot reject the hypothesis that relative income has no impact on subjective well-being in rural areas of northern Ethiopia.
