Business-to-business (B2B) exchanges are expected to bring about lower prices for buyers through reverse auctions. Analysis of such settings for seller pricing behavior often points to mixed-strategy equilibria. In real life, it is plausible that managers learn this complex ideal behavior over time. We modeled the two-seller game in a synthetic environment,(More)
BACKGROUND The objective of this research is to quantify the association between direct medical costs attributable to type 2 diabetes and level of glycemic control. METHODS A longitudinal analysis using a large health plan administrative database was performed. The index date was defined as the first date of diabetes diagnosis and individuals had to have(More)
Reverse auctions in Business-to-Business (B2B) exchanges provide numerous benefits to participants. Arguably the most notable benefit is that of lowered prices driven by increased competition in such auctions. The competition between sellers in reverse auctions has been analyzed using a game-theoretic framework and equilibria have been established for(More)
In an effort to reduce cost and improve quality, health care payers have enacted a number of incentives to motivate providers to focus their efforts on achieving better clinical outcomes and reducing the prevalence and progression of disease. In response to these incentives, providers are entering into new arrangements such as accountable care organizations(More)
Previous research in reverse auction B2B exchanges found that in an environment where sellers collectively can cater to the total demand, with the final (i.e. the highest-priced bidding) seller catering to a residual, the sellers resort to a mixed strategy equilibrium [2]. While price randomization in industrial bids is an accepted norm, it may be argued(More)
