Conventional explanations for this mutual forbearance depend on centralized firm decision-making, which permits the threat of concerted retaliation across many markets at once. However, in large firms, market-level decisions may be delegated to managers. We show that multi-market contact can still promote tacit collusion in this case, even though each manager cares only about profit in her own market. In our model, the main linkage between markets is informational: in collusive equilibria of a repeated game with noisy monitoring, outcomes in a second market may be evidence about a competitor's incentives in a first market. The model expands the antitrust concerns about multi-market contact to situations in which independent branch-level decision-making appears to be occurring.</p></div>","PeriodicalId":48127,"journal":{"name":"International Journal of Industrial Organization","volume":null,"pages":null},"PeriodicalIF":1.7,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142122417","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}

Additionally, third-party product prices are lower in expected terms under first-party selling, either because the platform reduces the commission fee (with self-preferencing) or downstream competition is fiercer (without self-preferencing).

Next, we empirically investigate price differentials in the U.S. airline industry, employing a new instrumental variables approach to isolate the effects of multimarket contact. We find that multimarket contact results in larger differences in fare levels amongst consumers purchasing higher-priced tickets but smaller fare differences amongst those purchasing lower-priced tickets. Consistent with our theoretical model, multimarket contact more strongly influences fares on less concentrated routes.

We find that industries with high robot exposure are characterized by dis-proportional increases in productivity in those firms that are already most productive to begin with. Those firms are able to increase their markups and overall profits, while less profitable firms within the same industry, country and year tend to see declining markups and profits. We also find that variation in robot exposure across industries is correlated with declining labor income shares, mainly through adjustments within firms that are initially large, productive and have low labor cost-to -sales ratios.
