A small proportion of the network has access to a private signal about the component, which can be clean (information) or distorted (misinformation). Other agents are uninformed and can receive information only from their peers. All agents are Bayesian, adjusting their beliefs according to the confidence they have in the source of information. We examine, by means of simulations, how information diffuses in the network and provide a framework to account for delayed absorption of shocks, that are not immediately priced as predicted by classical financial models. We investigate the effect of the network topology on the resulting asset price and evaluate under which condition misinformation diffusion can make the market more inefficient.</div></div>","PeriodicalId":48409,"journal":{"name":"Journal of Economic Behavior & Organization","volume":"238 ","pages":"Article 107211"},"PeriodicalIF":2.3,"publicationDate":"2025-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144903693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a spatial modelling framework where patients choose provider based on travelling distance and waiting times, we show that the effect is theoretically ambiguous. In the presence of cost synergies, the scope for lower waiting times as a result of the merger is larger if the hospitals are more profit-oriented. This result is arguably confirmed by our empirical analysis, which is based on difference-in-differences estimations using a long panel of data on hospital merger in the English National Health Service (NHS). While we find that hospital mergers lead to higher waiting times on average, we also show that the effects of a merger on waiting times crucially rely on a legal status that can reasonably be linked to the degree of profit-orientation. Whereas hospital mergers involving Foundation Trusts tend to reduce waiting times, the corresponding effect of mergers involving hospitals without this legal status tends to go in the opposite direction.</div></div>","PeriodicalId":48409,"journal":{"name":"Journal of Economic Behavior & Organization","volume":"238 ","pages":"Article 107196"},"PeriodicalIF":2.3,"publicationDate":"2025-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144895998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leveraging recent methodological advances, we estimate a staggered difference-in-difference aiming to eliminate biases arising from reverse causality or unobserved time-invariant unobserved heterogeneity and account for heterogenous treatment effects across cohorts and time. Our results suggest that leaving school before age 18 increases males’ likelihood of experiencing homelessness, being incarcerated, using cannabis daily and illegal street drugs weekly several years after school-leaving. In contrast, for females the difference-in-difference strategy fully eliminates the correlations between their school-leaving age and outcomes suggesting that remaining biases would likely be gender-specific. To minimise concerns that gender-specific time-varying unobserved heterogeneity may be driving our results, we also show that our results are robust to controlling for the lags of all other outcomes. Finally, we find that while the occurrence and the timing of parental separation coincide with early school-leaving, our preferred specification also eliminates this correlation. Taken together, our findings suggest that preventing early school-leaving can help disadvantaged youth break cycles of multi-dimensional disadvantage.</div></div>","PeriodicalId":48409,"journal":{"name":"Journal of Economic Behavior & Organization","volume":"238 ","pages":"Article 107205"},"PeriodicalIF":2.3,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144893207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The posted prize, entry fees, and productive resources promised to potential entrants jointly determine firms’ decisions to enter the competition and their effort supply. We characterize the respective optimal contests for two objectives: (i) maximizing total effort in the contest and (ii) maximizing the expected quality of the winning product. We show that the optimal contest induces the entry of only the two most efficient firms when the sponsor can jointly set entry fees and allocate productive resources. The resource allocation plan in the optimum may favor the initially more competent firm and thus promote a “national champion” instead of leveling the playing field, and the optimum depends on the nature of the R&D task and effort cost profiles of the firms.
