We show that LTCHs respond to the financial incentives of this system by disproportionately discharging patients after they cross the large-payment threshold. We find this occurs more often at for-profit facilities, facilities acquired by leading LTCH chains, and facilities colocated with other hospitals. Using a dynamic structural model, we evaluate counterfactual payment policies that would provide substantial savings for Medicare.}, Doi = {10.1257/aer.20170092}, Key = {fds325455} } @article{fds343587, Author = {Li, Y and Mazur, L and Park, Y and Roberts, JW and Sweeting, A and Zhang, J}, Title = {Endogenous and Selective Service Choices after Airline Mergers}, Year = {2018}, Month = {January}, Key = {fds343587} } @article{fds343588, Author = {Garrett, D and Ordin, A and Roberts, JW and Suárez Serrato, JC}, Title = {Tax Advantages and Imperfect Competition in Auctions for Municipal Bonds}, Year = {2017}, Month = {June}, Key = {fds343588} } @article{fds320614, Author = {Bayer, PJ and Mangum, K and Roberts, JW}, Title = {Speculative Fever: Investor Contagion in the Housing Bubble}, Journal = {Economic Research Initiatives at Duke (Erid) Working Paper}, Number = {211}, Pages = {51 pages}, Year = {2016}, Month = {February}, Abstract = {Historical anecdotes of new investors being drawn into a booming asset market, only to suffer when the market turns, abound. While the role of investor contagion in asset bubbles has been explored extensively in the theoretical literature, causal empirical evidence on the topic is virtually non-existent. This paper studies the recent boom and bust in the U.S. housing market, and establishes that many novice investors entered the market as a direct result of observing investing activity of multiple forms in their own neighborhoods, and that “infected” investors performed poorly relative to other investors along several dimensions.}, Key = {fds320614} } @article{fds323213, Author = {Roberts, JW and Sweeting, A}, Title = {Bailouts and the preservation of competition: The case of the federal timber contract payment modification act}, Journal = {American Economic Journal: Microeconomics}, Volume = {8}, Number = {3}, Pages = {257-288}, Publisher = {American Economic Association}, Year = {2016}, Month = {January}, url = {http://dx.doi.org/10.1257/mic.20150070}, Abstract = {We estimate the value of competition in United States Forest Service (USFS) timber auctions, in the context of the Reagan administration's bailout of firms that faced substantial losses on existing contracts. We use a model with endogenous entry by asymmetric firms, allowing survivors to respond to the exit of bailed-out firms by entering more auctions and for these marginal entrants to have lower values than firms that would choose to enter in any event, a selective entry effect. Observed asymmetries and selective entry contribute to us finding that the bailout may have increased USFS revenues in subsequent auctions quite substantially.}, Doi = {10.1257/mic.20150070}, Key = {fds323213} } @article{fds325777, Author = {Bayer, PJ and Geissler, C and Mangum, K and Roberts, JW}, Title = {Speculators and Middlemen: The Strategy and Performance of Investors in the Housing Market}, Journal = {Economic Research Initiatives at Duke (Erid) Working Paper}, Number = {93}, Year = {2015}, Month = {January}, Key = {fds325777} } @article{fds325934, Author = {Bhattacharya, V and Roberts, JW and Sweeting, A}, Title = {Regulating bidder participation in auctions}, Journal = {The Rand Journal of Economics}, Volume = {45}, Number = {4}, Pages = {675-704}, Publisher = {WILEY}, Year = {2014}, Month = {December}, url = {http://dx.doi.org/10.1111/1756-2171.12067}, Doi = {10.1111/1756-2171.12067}, Key = {fds325934} } @article{fds325935, Author = {Gedge, C and Roberts, JW and Sweeting, A}, Title = {A Model of Dynamic Limit Pricing with an Application to the Airline Industry}, Year = {2014}, Month = {July}, Key = {fds325935} } @article{fds285766, Author = {Mcdevitt, RC and Roberts, JW}, Title = {Market structure and gender disparity in health care: Preferences, competition, and quality of care}, Journal = {The Rand Journal of Economics}, Volume = {45}, Number = {1}, Pages = {116-139}, Publisher = {WILEY}, Year = {2014}, Month = {March}, ISSN = {0741-6261}, url = {http://dx.doi.org/10.1111/1756-2171.12044}, Abstract = {We consider the relationship between market structure and health outcomes in a setting where patients have stark preferences: urology patients disproportionately match with a urologist of the same gender. In the United States, however, fewer than 6% of urologists are women despite women constituting 30% of patients. We explain a portion of this disparity with a model of imperfect competition in which urology groups strategically differentiate themselves by employing female urologists. These strategic effects may influence women's health, as markets without a female urologist have a 7.3% higher death rate for female bladder cancer, all else equal. © 2014, RAND.}, Doi = {10.1111/1756-2171.12044}, Key = {fds285766} } @article{fds285767, Author = {Roberts, JW}, Title = {Unobserved heterogeneity and reserve prices in auctions}, Journal = {The Rand Journal of Economics}, Volume = {44}, Number = {4}, Pages = {712-732}, Publisher = {WILEY}, Year = {2013}, Month = {December}, ISSN = {0741-6261}, url = {http://dx.doi.org/10.1111/1756-2171.12038}, Abstract = {This article shows how reserve prices can be used to control for unobserved object heterogeneity to identify and estimate the distribution of bidder values in auctions. Reserve prices are assumed to be monotonic in the realization of unobserved heterogeneity, but not necessarily set optimally. The model is estimated using transaction prices from a used car auction platform to show that the platform enables sellers to capture a large fraction of the potential value from selling their vehicle. Individual sellers benefit mostly from access to a large set of buyers, but the magnitude depends on accounting for unobserved heterogeneity. © 2014, RAND.}, Doi = {10.1111/1756-2171.12038}, Key = {fds285767} } @article{fds285768, Author = {Roberts, JW and Sweeting, A}, Title = {When Should Sellers Use Auctions?}, Journal = {American Economic Review}, Volume = {103}, Number = {5}, Pages = {1830-1861}, Publisher = {American Economic Association}, Year = {2013}, Month = {August}, ISSN = {0002-8282}, url = {http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000322878200009&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=47d3190e77e5a3a53558812f597b0b92}, Doi = {10.1257/aer.103.5.1830}, Key = {fds285768} } %% Working Papers @article{fds158824, Author = {Ben Handel and Kanishka Misra and James W.
