The time cost is usually unknown ex ante and its presence and duration must be inferred as the search progresses. We disentangle the effect of time cost on search behavior from people’s (in)ability to perceive time delay between offers. We find that people are able to infer the existence of the time cost, but their inference is imperfect. We also compare the effect of time cost with the effect of monetary cost and find that the time cost reduces the amount of exerted search, but not as much as the monetary cost does. Discriminating between the effects is critical for increasing the empirical validity of search models and designing mechanisms capable of improving the quality of decisions, especially in unfamiliar or infrequently encountered situations.","PeriodicalId":153208,"journal":{"name":"ERN: Search","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125939296","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}

Investors have heterogeneous beliefs about the worst case return of a risky asset and take leverage to buy it. When the worst case becomes more likely, forced liquidations result in price crashes, which investors mistake for negative information about worst case returns. They therefore revise cash flow expectations downwards, henceforth requiring larger returns. The model predicts that crashes lead to persistent changes in future average returns and that larger crashes are followed by larger changes. To link the model to historical crashes, I consider two strategies associated with the Black Monday crash in 1987 and the Lehman Brothers bankruptcy in 2008. Hedged put options selling suffered severe losses around Black Monday, while arbitraging the difference in implied credit risk between the corporate bond and CDS markets was similarly negatively affected after the Lehman bankruptcy. The losses on these strategies in those crisis episodes were likely exacerbated by deleveraging, but the increased returns after the crashes have been remarkably persistent, consistent with the implications of my model.","PeriodicalId":153208,"journal":{"name":"ERN: Search","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115750341","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 develop a theory of matching markets under floor constraints. We introduce a stability notion, which we call floor respecting stability, for markets in which (hard) floor constraints must be respected. A matching is floor respecting stable if there is no coalition of doctors and hospitals that can propose an alternative matching that is feasible and an improvement for its members. Our stability notion imposes the additional condition that a coalition cannot reassign a doctor outside the coalition to another hospital (although she can be fired). This condition is necessary to guarantee the existence of stable matchings. We provide a mechanism that is strategy‐proof for doctors and implements a floor respecting stable matching.","PeriodicalId":153208,"journal":{"name":"ERN: Search","volume":"164 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123281562","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}

Net capital flows that arise due to idiosyncratic firm upgrades and downgrades cause significant price movements for the other bonds in the effected rating bucket. A one-standard-deviation flow into a rating bucket generates a 5 bp bond price reduction, equivalent to 4.1% of the monthly price variation driven by macro variables. This effect is highly persistent, with an approximate half-life of five months. Guided by the model, we also document a significant decaying spillover pattern to bond prices in adjacent buckets.","PeriodicalId":153208,"journal":{"name":"ERN: Search","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133863900","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}

But some actions may be detrimental to some members, thus jeopardizing the organization's sustainability. This tradeoff caps organization size and limits the resulting welfare improvement. Organizations can exist only if coordination motives dominate the diversity of the population, up to a size limit.
