Consumerism arises when patients acquire and use medical information from sources other than their physicians. This practice has been hailed as a means of improving quality. This need not be the result. Our theoretical model identifies a channel through which consumerism may reduce quality:...

World food prices have increased dramatically in recent years. We use panel data from 2006 to examine the impact of these increases on the consumption and nutrition of poor households in two Chinese provinces. We find that households in Hunan suffered no nutrition declines. Households in Gansu...

This paper presents a model of strategic interaction in which a third party intervenes on behalf of a government in its conflict with insurgents. It examines whether it is better for the intervenor to adopt an input-based strategy (i.e., specify the total resources it will spend) or an...

Many developing countries use food price subsidies or price controls to improve the nutrition of the poor. However, subsidizing goods on which households spend a high proportion of their budget can create large wealth effects. Consumers may then substitute towards foods with higher...

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...

Humans naturally dispose of objects that disgust them. Is this phenomenon so deeply embedded that even incidental disgust - i.e., where the source of disgust is unrelated to a possessed object - triggers disposal? Two experiments were designed to answer this question. Two film clips served as...

For several decades now a debate has raged about policy-making by litigation. Spurred by the way in which tobacco, environmental, and other litigation has functioned as an alternative form of regulation, the debate asks whether policy-making or regulation by litigation is more or less socially...

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...

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...
