This study assesses the factors influencing the movement of people across health plans. We distinguish three types of cost-related transitions: adverse selection, the movement of the less healthy to more generous plans; adverse retention, the tendency for people to stay where they are when they...

Medicare continues to implement payment reforms that shift reimbursement from fee-for-service towards episode-based payment, affecting average and marginal reimbursement. We contrast the effects of two reforms for home health agencies. The Home Health Interim Payment System in 1997 lowered both...

In this survey chapter on pricing and reimbursement in U.S. pharmaceutical markets, we first provide background information on important federal legislation, institutional details regarding distribution channel logistics, definitions of alternative price measures, related historical...

Over 2009-2019 the seemingly inexorable rise in health care’s share of GDP markedly slowed, both in the US and elsewhere. To address whether this slowdown represents a reduced steady-state growth rate or just a temporary pause we specify and estimate a decomposition of health care spending...

The BP Deepwater Horizon oil spill highlighted the glaring weakness in the current liability and regulatory regime for oil spills and for environmental catastrophes more broadly. This article proposes a new liability structure for deep sea oil drilling and for catastrophic risks generally. It...

There is a low but uncertain probability that climate change could trigger “mega-catastrophes,” severe and at least partly irreversible adverse effects across broad regions. This paper first discusses the state of current knowledge and the defining characteristics of potential climate change...

Policymaking for posterity involves current decisions with distant consequences. Contrary to conventional prescriptions, we conclude that the greater wealth of future generations may strengthen the case for preserving environmental amenities; lower discount rates should be applied to the far...
