Intermediaries may bargain with several upstream providers on behalf of consumers who do not directly pay for consumption, such as an insurer bargaining with hospitals. We show that the common Nash- in-Nash solution, while useful for estimation, can predict Nash overpricing: prices that exceed...

One of the reasons why regulators are hesitant about permitting price competition in healthcare markets is that it may damage quality when information is poor. Evidence on whether this fear is well-founded is scarce. We provide evidence using a reform that permitted Dutch health insurers and...

We analyze health care option demand markets with vertical restraints divided along two dimensions: naked and conditional exclusion, and vertical integration; applicable to the upstream, the downstream, and both markets. Our unified framework includes forward and backward integration, and joint...

We present a newly designed market experiment to study regulatory issues in markets with advice inspired by the models of Inderst and Ottaviani (2012a) and Inderst (2015). In line with our predictions, our experimental markets create conflicts of interest and unsuitable advice biased toward...

Bargaining is all around us. Bargaining is how prices are set across a range of economic activities such as between licensors and licensees of intellectual property, employees and employers, content providers and distributors, health insurers and hospitals, and in many intermediate product...

We develop a model of gestational surrogacy, in which a childless couple faces heterogeneous prospective surrogates. High-type surrogates add more value but also have higher outside options. Surrogates can make specific investments for the overall well-being (care) of the unborn child. We show...

I assess the extent to which the gender gap in physician earnings may be driven by physicians' preference for referring to specialists of the same gender. Analyzing administrative data on 100 million Medicare patient referrals, I provide robust evidence that doctors refer more to specialists of...

Many service industries, including the medical and legal professions in some countries, display a gated structure. Rather than approaching a final producer directly, a consumer will first seek a referral from an intermediary. In this paper, we provide one possible explanation for such an...

Many service industries, including the medical and legal professions in some countries, display a gated structure. Rather than approaching a final producer directly, a consumer will first seek a referral from an intermediary. Such an industry structure might help to alleviate adverse selection...

While much of the commentary on obstacles to stem cell research focuses on patents, material transfer agreements (MTAs) governed by state contract and property law present equal if not greater challenges to researchers. This Article argues that the life sciences in general, and the stem cell...
