   Abstract = {Medicare's prospective payment system for long-term
             acute-care hospitals (LTCHs) provides modest reimbursements
             at the beginning of a patient's stay before jumping
             discontinuously to a large lump-sum payment after a
             prespecified number of days. 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.},

   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.},

   Title = {Bailouts and the preservation of competition: The case of
             the federal timber contract payment modification

   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.},

   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.},

   Journal = {The Rand Journal of Economics},
   Volume = {44},
   Number = {4},
   Pages = {712-732},
   Publisher = {WILEY},

   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.},
