Using data from all public procurement events in Italy between 2012 and 2019, and exploiting a difference-in-differences model where pacemakers play the role of the control group, we find that the merger led to a 7.6% increase in prices and that this effect is concentrated in the first three years post-merger. Further insights are: (i) a heterogeneous impact among gender and age groups such that most of the burden is on female patients aged 65 and above; (ii) short-term quality does not change, but patenting activity declines; (iii) there is no evidence of the merger triggering ex-post coordinated effects in the form of bidding and entry patterns compatible with firm collusion.</p>\u0000 </div>","PeriodicalId":47963,"journal":{"name":"Journal of Industrial Economics","volume":"73 2","pages":"254-284"},"PeriodicalIF":1.7,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144264353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Social welfare can be higher when a monopoly sells to a monopoly, with double margins, than when a competitive industry sells to a downstream Cournot oligopoly with differing efficiency levels. This requires inverse demand to be sufficiently concave, and cannot hold when demand is convex. When there are no vertical issues conditions are found for elimination of an inefficient firm to raise welfare, building on Lahiri and Ono (1988).

Leading players in the industry (e.g., the Booking Group) hold two types of platforms in their portfolio: revealing platforms that disclose the identity of transaction partners (like Booking.com) and anonymous platforms that do not (like Hotwire.com). Anonymous platforms offer discounts but lead to inefficient matching between consumers and firms. We develop a model in which horizontally differentiated firms sell to heterogeneous consumers both directly and via a platform that enlarges the pool of consumers they can attract. The platform charges firms for transactions it intermediates and can choose to offer an anonymous sales channel in addition to a revealing one. We show that offering both sales channels is profitable not only because it allows the platform to implement price discrimination, as suggested by the literature on opaque selling, but also because it improves rent extraction. The anonymous channel breaks the link between the price on the revealing channel and the firms' outside option; moreover, it can reduce double marginalisation. The welfare impact of the anonymous channel is ambiguous: while it sometimes leads to market expansion, it also causes inefficiently high transport costs.</p>","PeriodicalId":47963,"journal":{"name":"Journal of Industrial Economics","volume":"73 1","pages":"124-166"},"PeriodicalIF":1.7,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/joie.12404","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142222768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But does this variation affect every consumer to the same extent? Previous literature finds price dispersion exists even for homogeneous goods, at least partially as a result of heterogeneity in consumer engagement with the market. We study this question by linking demographic and income heterogeneity across local areas to the impact of changing market concentration on markups. With 15 years of station-level motor fuel price data from Western Australia and information on instances of local market exit and entry, we apply a non-parametric causal forest approach to explore the heterogeneity in the effect of exit/entry. The paper provides evidence of the distributional effect of changing market concentration. Areas with lower income experience a larger increase in petrol stations' price margin as a result of market exit. On the other hand, entry does not benefit the same low-income areas with a larger reduction in the margin than in high-income areas. Policy implications include a need to further focus on increasing engagement by low-income consumers.</p>","PeriodicalId":47963,"journal":{"name":"Journal of Industrial Economics","volume":"73 1","pages":"70-123"},"PeriodicalIF":1.7,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/joie.12403","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142222769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
