“…Clearly, as the number of their agency encounters increases, the impact a patient has on the BMIX index increases quadratically. We are not aware of this measure having been previously developed in the network literature (although it is related to market overlap measures, as in Aryal et al, 2020); the presence of the indicator function in for the = 1 case makes the weights and function as a whole a mixture of patients that do ( > 1) and do not ( = 1) contribute to the network, thus making BMIX a mixture of two forms of information.…”

Multimarket Contact in the Hospital Industry

“…Between 2000 and 2010, an average of around 60 general acute care hospital merger and acquisition (M&A) deals occurred each year, 1 with the pace quickening to nearly 100 deals per year between 2011 and 2014. 2 When competing hospitals merge, the combined entity may have greater bargaining leverage in negotiations with insurers, thereby leading to higher prices. Structural merger simulation models often predict substantial price increases resulting from the merger of competing hospitals (e.g., Capps, Dranove, andSatterthwaite 2003 andGowrisankaran, Nevo, andTown 2015), and reduced form studies have found price increases as high as 40 percent (Dafny 2009).…”
