We estimate an insurer-specific preference function which rationalizes hospital referrals for privately insured births in California. The function is additively separable in: a hospital price paid by the insurer, the distance traveled, and plan- and severity-specific hospital fixed effects...

This paper exploits a sharp reduction in patient cost sharing at age 70 in Japan, using a regression discontinuity design to examine its effect on utilization, health, and financial risk arising from out-of-pocket expenditures. Due to the national policy, cost sharing is 60–80 percent lower at...

I use data on the hospital networks offered by managed care health insurers to estimate the expected division of profits between insurers and providers. I include a simple profit-maximization framework and an additional effect: hospitals that can secure demand without contracting with all...

To gauge the competitiveness of the group health insurance industry, I investigate whether health insurers charge higher premiums, ceteris paribus, to more profitable firms. Such "direct price discrimination" is feasible only in imperfectly competitive settings. Using a proprietary national...

Expected consumer's surplus rarely represents preferences over price lotteries. Still, I give sufficient conditions for policies which maximize aggregate expected surplus to be interim Pareto Optimal. Besides two standard partial equilibrium conditions, I assume that feasible prices satisfy a...

We analyze firms that compete by means of exclusive contracts and market-share discounts (conditional on the seller's share of customers' total purchases). With incomplete information about demand, firms have a unilateral incentive to use these contractual arrangements to better extract buyers'...

Resale price maintenance (RPM), slotting fees, loyalty rebates, and other related vertical practices can allow an incumbent manufacturer to transfer profits to retailers. If these retailers were to accommodate entry, upstream competition could lead to lower industry profits and the breakdown of...

In their comment, Taylor, Kreisle and Zimmerman use gasoline price data taken from fleet card transactions at selected gasoline stations to re-examine a subset of results presented in Hastings (2004). Bringing new data to re-examine the question is a helpful contribution. Both data sets have...
