When developers monetize their apps by charging users (or through in-app advertising), they must pay commissions to the app platform (or ad platform). Both platform markets are interconnected, as developers choose which market to use for monetization (paid or ad-funded). The model shows that app and ad platforms are substitutes for app developers. Thus, an imbalance between app and ad commissions induces some developers to choose inefficient business models. For example, if the app commission is lower than the ad commission, some ad-friendly developers may choose the paid business model even though they could generate a greater surplus from advertising from a social welfare perspective. This finding highlights the benefits of distinct platforms setting similar commissions. The model is also used to evaluate the impact of a non-price strategy implemented by the app platform to limit the ability of app developers to monetize through advertising. The analysis shows that the app platform can use this non-price strategy to increase its demand at the expense of the ad platform.</div></div>","PeriodicalId":48127,"journal":{"name":"International Journal of Industrial Organization","volume":"97 ","pages":"Article 103117"},"PeriodicalIF":1.7,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142661687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For example, a patient seeking medical treatment is indifferent to the treatment's cost if it is covered by his insurance program. We study bargaining for per-unit prices between suppliers and an intermediary who represents price-insensitive consumers. Under the commonly used simultaneous bargaining framework we show that, if suppliers have sufficiently high bargaining power, the resulting prices will exceed the value of the good (or service) being delivered. This overpricing is solved if simultaneous negotiations are replaced by sequential ones. The theoretical problem with sequential negotiations is that they necessitate treating the suppliers asymmetrically, even if they are symmetric; the empirical problem with sequential negotiations is that the negotiations-order is unobservable. We propose a multi-period model that resolves these issues: overpricing is prevented and all suppliers are treated the same. In this model, the result about sequential negotiations is utilized in order to produce (asymmetric) off-path threats. These threats sustain symmetric on-path play.</div></div>","PeriodicalId":48127,"journal":{"name":"International Journal of Industrial Organization","volume":"97 ","pages":"Article 103107"},"PeriodicalIF":1.7,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142326819","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}

Several U.S. markets employ algorithms to monitor and mitigate market power abuse in real-time. The performance of automated mitigation procedures is contingent on precise estimates of firms' marginal production costs. Currently, marginal cost is inferred from the past offers of a plant. We present new estimation approaches and compare them to the currently applied benchmark method. We test the performance of all approaches on auction data from the Iberian power market. The results show that our novel approaches outperform the benchmark approach significantly, reducing the mean (median) absolute estimation error from 11.53 (6.08) €/MWh in the benchmark to 4.03 (2.64) €/MWh for our preferred approach. This approach also performs best in our subsequent simulation of mitigation procedures. Here we find large welfare transfers from supplier to buyer surplus as well as a robust overall welfare gain, stemming from both productive and allocative efficiency gains. Our research contributes to accurate monitoring of market power and improved automated mitigation.
