Preferences of agents are modeled by a generalized life-cycle utility function allowing for temporal risk aversion. We identify conditions for pricing bounds under which agents subject to temporal risk aversion prefer to invest positive fractions of wealth in both annuities and tontines to full annuitization. In an extended model with differential mortality and wealth, we analyze a utilitarian social planner's retirement product demand, focusing on wealth transfers between the groups.","PeriodicalId":281936,"journal":{"name":"ERN: Other Microeconomics: Decision-Making under Risk & Uncertainty (Topic)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131312654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a menu choice framework, we provide an axiomatic characterization of the model, identify its parameters (a utility function, an increasing transformation, a second-order prior belief, and an information cost function), and behaviorally compare the costs. Our results show that the rational inattention model, which has found various applications in the literature, is a special case of the costly Bayesian learning model. We identify several behavioral conditions each of which can be used to test if the decision maker is rationally inattentive or is of a more general type Bayesian learner including those who exhibit aversion to uncertainty. We argue that our decision makers can have flexible attitudes towards the timing of resolution of uncertainty.","PeriodicalId":281936,"journal":{"name":"ERN: Other Microeconomics: Decision-Making under Risk & Uncertainty (Topic)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128083672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Similarly, account attributes such as account age, account size, and extreme underdiversification (holding a single stock) are associated with particular characteristic preferences. Coheld stocks tend to have higher return covariance, suggestive of the importance of clientele effects in the stock market.","PeriodicalId":281936,"journal":{"name":"ERN: Other Microeconomics: Decision-Making under Risk & Uncertainty (Topic)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127895628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many well documented choice anomalies under risk (e.g., the common consequence and ratio effects) show that even weaker forms of independence can be violated by experimental subjects. We demonstrate that these violations have a close relation when continuity holds, but their connection becomes less pronounced when continuity is dropped. We show that while retaining the independence axiom, replacing continuity with two intuitive conditions, substitution and monotonicity, can characterize the expected utility model. In this case, weakening the independence axiom can still yield an expected utility, but in a weaker sense implying that our axiomatization is tight.","PeriodicalId":281936,"journal":{"name":"ERN: Other Microeconomics: Decision-Making under Risk & Uncertainty (Topic)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121182751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We provide an axiomatic characterization of the model, and show how costs of adaption can be elicited and compared across individuals. In a moral hazard problem we show that adaption of risk assessments can weaken the effect of monetary incentives for effort provision, which have important implications for agency problems. We also provide several examples to illustrate how adaption of risk assessments can rationalize many well-known choice anomalies (e.g., the common consequence, certainty, or magnitude effects). These behavioral implications follow from a key feature of the model that adaption decisions can respond to changes in incentives.","PeriodicalId":281936,"journal":{"name":"ERN: Other Microeconomics: Decision-Making under Risk & Uncertainty (Topic)","volume":"190 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132453619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We build a model in which each spouse has a risk preference and must bargain with each other to make asset decisions for the household. By structurally estimating the model with longitudinal data from Australian households, we show that the average household’s asset allocation reflects the husband’s risk preference 44% more than the wife’s. This gap in bargaining power is partially explained by gender differences in income and employment status, but is also due to gender effects. We provide further evidence that links the distribution of bargaining power to views on gender norms in the cross-section.","PeriodicalId":281936,"journal":{"name":"ERN: Other Microeconomics: Decision-Making under Risk & Uncertainty (Topic)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124660877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We find that a decrease in analyst coverage promotes an increase in insurers’ risk-taking, which is mainly driven by insurers with smaller initial analyst coverage and those operating in an environment of lower product market competition. We also show that the decrease in analyst coverage causes more risky investment behaviors, more risky underwriting, and less conservative reserving practice.","PeriodicalId":281936,"journal":{"name":"ERN: Other Microeconomics: Decision-Making under Risk & Uncertainty (Topic)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122010444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Without completeness, decision making depends on a set of beliefs, and an action is preferred to another if and only if it has larger expected utility for all beliefs in this set. We consider two natural notions of incentive compatibility in this setting: maximal incentive compatibility requires that no strategy has larger expected utility than reporting truthfully for all beliefs, while optimal incentive compatibility requires that reporting truthfully has larger expected utility than all other strategies for all beliefs. In a model with a continuum of types, we show that optimal incentive compatibility is equivalent to ex-post incentive compatibility under fairly general conditions on beliefs. In a model with a discrete type space, we characterize full extraction of rents generated from private information. We show that full extraction is generically possible with maximal incentive compatible mechanisms, but requires sufficient disagreement across types, which neither holds nor fails generically, with optimal incentive compatible mechanisms.","PeriodicalId":281936,"journal":{"name":"ERN: Other Microeconomics: Decision-Making under Risk & Uncertainty (Topic)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122459186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
