Using a unique dataset spanning the period 1996-2011, we find that the welfare impact of the GE innovation is significant. In the last five years of the period analyzed, our preferred counterfactual indicates that total surplus due to GE traits was $5.18 billion per year, with seed manufacturers appropriating 56% of this surplus. The seed industry obtained more surplus from GE corn, whereas farmers received more surplus from GE soybeans.","PeriodicalId":51342,"journal":{"name":"Rand Journal of Economics","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2019-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/1756-2171.12290","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44437926","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}

Oligopoly competition in successive industries is shown to give rise to a vertical externality and a horizontal externality. If a collusive price of intermediate goods better balances the two externalities, the collusion will raise the joint profit of all firms in the two industries and is therefore profitable for the upstream after compensation of downstream firms.","PeriodicalId":51342,"journal":{"name":"Rand Journal of Economics","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/1756-2171.12271","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49025689","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 establish necessary and sufficient conditions on demand properties—cross/own elasticities and curvature—for differential pricing by symmetric firms to raise aggregate consumer surplus, profit, and total welfare. The analysis reveals intuitively why differential pricing is generally beneficial though not always—including why profit can fall, unlike for monopoly—and why it is more beneficial than oligopoly third-degree price discrimination. When firms have asymmetric costs, however, differential pricing can reduce profit or consumer surplus even with ‘simple’ demands such as linear.","PeriodicalId":51342,"journal":{"name":"Rand Journal of Economics","volume":"1 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2019-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/1756-2171.12363","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41381089","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}

Focusing on hospital mergers across distinct geographic markets, we show that such combinations can reduce competition among merging hospitals for inclusion in insurers' networks, leading to higher prices (or lower‐quality care). Using data on hospital mergers from 1996–2012, we find support that this mechanism operates within state boundaries: cross‐market, within‐state hospital mergers yield price increases of 7%–9 % for acquiring hospitals, whereas out‐of‐state acquisitions do not yield significant increases.","PeriodicalId":51342,"journal":{"name":"Rand Journal of Economics","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2019-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/1756-2171.12270","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42164692","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 parties will settle immediately upon the arrival of information. However, they may also agree to settle prior to an arrival. We derive the settlement dynamics prior to an arrival: negotiations result in either immediate agreement, a weak deadline effect—settling at a particular date before the deadline, a strong deadline effect—settling at the deadline, or impasse, depending on the level of optimism.

Whereas previous studies focused on manufacturers active in independent markets, we analyze pools licensing to competing manufacturers, allowing for multiple licensors and nonlinear tariffs. We find that the impact of pools on welfare depends on the industry structure: whereas they are procompetitive when no manufacturer is integrated with a licensor, the presence of vertically integrated manufacturers triggers a novel trade‐off between horizontal and vertical price coordination. Specifically, pools are anticompetitive if the share of integrated firms is large, procompetitive otherwise. We then formulate information‐free policies to screen anticompetitive pools.","PeriodicalId":51342,"journal":{"name":"Rand Journal of Economics","volume":" ","pages":""},"PeriodicalIF":2.3,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1111/1756-2171.12266","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44460530","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}
