Online information may improve health outcomes if it reduces information frictions and helps patients choose higher quality providers or causes providers to improve quality. We examine how health outcomes for common procedures in Medicare changed after broadband internet rolled out across ZIP Codes from 1999 to 2008. Estimates imply that broadband expansion improved health outcomes by 5%. Broadband access primarily helped patients choose higher-quality providers; we also find some evidence that broadband improved provider quality. We use a structural model to decompose the improvements in patient outcomes over time. Counterfactual simulations imply that broadband roll-out was responsible for 16% of the improvement in outcomes by the end of the period.</p></div>","PeriodicalId":48127,"journal":{"name":"International Journal of Industrial Organization","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140905359","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}

We find that a ban of either price component of the two-part tariff makes it more difficult to sustain collusion at profit-maximizing prices.

Under some zonal market designs, where profit-maximizing participants face a uniform regional price, achieving lowest-cost system-wide production can be impossible. Further, zonal designs can incentivize siting of intermittent renewables in inefficient locations behind network constraints, of concern for jurisdictions undergoing a clean energy transition. We develop measures of mispricing that compare the zonal prices generators receive to locational marginal prices that value congestion externalities from generator output. We apply these measures to show wind and solar generators are increasingly siting in constrained areas of the Australian network, and highlight sources of potential efficiency gains from adopting a nodal market design with locational marginal pricing.</p></div>","PeriodicalId":48127,"journal":{"name":"International Journal of Industrial Organization","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0167718724000249/pdfft?md5=dc0c2c439c0ae754a97e94e2c56eef34&pid=1-s2.0-S0167718724000249-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140605357","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}

We model programming decisions as the outcome of a discrete game played by rival stations competing for advertising revenue (which depends on viewing) by choosing lineups of local news and entertainment broadcasts. Using program-level data on television viewing and advertising prices, we find modest under-provision of local news relative to the level that maximizes television viewing. Counterfactual simulations indicate an average deficit of 7.4 broadcasts per market, or 12.8% of local station broadcasts during the evening news hours. Most of this shortfall is in the 7:30 timeslot leading into prime time. We distinguish two sources of inefficiency: losses due to advertiser valuation of local news and entertainment viewers, and losses from classic business stealing. Losses from competition represent about one third of the estimated shortfall, suggesting gains to cooperation among competing stations.</p></div>","PeriodicalId":48127,"journal":{"name":"International Journal of Industrial Organization","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140551792","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}

An important question for the management of a firm's R&amp;D and for public innovation policies is: What is more beneficial for the generation of firm innovations, external knowledge created by PROs or by universities? In this paper, we assess the impact of external knowledge from PROs versus universities on firm innovativeness. We use information on R&amp;D acquisitions from a panel dataset of more than 10,000 Spanish firms from 2005 to 2014. We show that external knowledge from PROs and universities increases firm innovativeness. Our results suggest that knowledge generated by PROs is more sensitive to the absorptive capacity of the firm than knowledge generated by universities. This has implications for research policy, R&amp;D management, and organizational strategies of firms’ knowledge activities. Firms with low absorptive capacities benefit relatively more from knowledge generated by universities than from knowledge generated by PROs. Moreover, R&amp;D managers should plan both their external and internal R&amp;D if they acquire external R&amp;D from PROs.</p></div>","PeriodicalId":48127,"journal":{"name":"International Journal of Industrial Organization","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2024-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139743486","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}
