In a Lotto lottery, the probability of winning a prize is known, but the size of the prize is unknown. This paper proposes a theoretical framework to model preferences over Lotto lotteries as compound lotteries. The first stage determines whether a prize is obtained, while the second stage determines the size of the prize. Then the paper empirically analyses human behaviour when uncertainty can be described as a Lotto lottery. There is considerable heterogeneity in the subjects’ aversion to lotteries with unknown payoffs. Further analysis shows that choices of decision makers can be best explained by a combination of risk and ambiguity preferences. These results suggest that subjects treat unknown payoffs similar to known payoffs with ambiguous probabilities.</div></div>","PeriodicalId":51637,"journal":{"name":"Journal of Behavioral and Experimental Economics","volume":"114 ","pages":"Article 102310"},"PeriodicalIF":1.6,"publicationDate":"2024-11-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142746972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, if the gender gap reflects socially constructed norms, it should be smaller among East Germans. Using data of the German Socio-Economic Panel (SOEP), our empirical analysis confirms this prediction. Specifically with respect to career and financial matters, the gender gap in risk tolerance is smaller among East Germans.

By conducting the survey in Norway and Sweden, which adopted very different strategies to handle the COVID-19 pandemic, we analyze potential differences in privacy attitudes due to policy changes. We find that privacy concern is negatively correlated with allowing public use of personal data. Trust in the entity collecting data and collectivist preferences are positively correlated with this type of data usage. Providing more information about the public benefit of sharing personal data makes respondents more positive to the use of their data, while providing additional information about the costs associated with data sharing does not change attitudes. The analysis suggests that stating a clear purpose and benefit for the data collection makes respondents more positive about sharing. Despite very different policy approaches, we do not find any major differences in privacy attitudes between Norway and Sweden.

Our sample demonstrates high levels of inconsistent behavior, with 48 % of the farmers exhibiting some type of inconsistency. Depending on the country, inconsistencies are explained by poverty, gender, and/or the interaction of gender and level of education. We find no significant impact (negative or positive) of education alone in all but one country model. Furthermore, we find session fixed effects to significantly explain inconsistencies in many cases, suggesting that session-specific circumstances, including inconsistencies across enumerators, play a crucial role in the successful implementation of these experiments. Our findings suggest that using risk attitude parameters without accounting for the presence and the potential causes of inconsistency may lead to unreliable results.

Treating the unanticipated start of the war in Ukraine on the 24th of February 2022 as a natural experiment, we find that both short- and long-term inflation expectations increased as an immediate result of the invasion. Long-term inflation expectations increased by around 0.4 percentage points, while the impact on short-term inflation expectations was more than twice as large - around one percentage point. These significant deviations from the central bank’s target, highlight an elevated risk of de-anchoring of inflation expectations early in March 2022. Looking into the possible mechanisms of this increase, we suggest that it can be partially attributed to individuals’ fears of soaring energy prices and increasing pessimism about economic trends in general.

We systematically test the presence of update bias in panel data by comparing teenage religiosity obtained from adults first in 2019 and later in 2022 in the Netherlands. Respondents who become more (less) religious in 2022 than 2019 are likelier to report a higher (lower) teenage religiosity in 2022. Even when we use data with a narrower gap (2019 and 2020 survey waves), we still obtain similar results. Overall, the analysis provides strong evidence for update bias. We suggest that the theory of cognitive dissonance best explains our findings; individuals manipulate their teenage religiosity to minimize dissonance between the past and current religious state and to obtain a higher satisfaction.
