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...

Why is private investment so low in Gulf compared to Western countries? We investigate cross-regional differences in trust and reference points for trustworthiness as possible factors. Experiments controlling for cross-regional differences in institutions and beliefs about trustworthiness reveal...

We study the problem of allocating multiple items to two agents whose cardinal preferences are private information. If money is available, Bayesian incentive compatibility and ex-ante Pareto efficiency can be achieved using the Expected Externality Mechanism (EEM). Absent money, under certain...

A single large loss may impact our networked financial system significantly differently than would a same cumulative magnitude sequence of moderate losses. Banks can choose whether to bail out their creditors after each loss in a sequence, or to walk away. Banks make bailout decisions...

Ordeals are burdens placed on individuals that yield no direct benefits to others. They represent a dead-weight loss. Ordeals – the most common being waiting time – play a prominent role in health care. Their goal is to direct scarce resources to recipients receiving greater value from them,...

This paper argues that historical analysis, necessarily written with hindsight, often underestimates the uncertainties of the past. We call this tendency explanation bias. This bias leads individuals – including professional historians – to imply greater certainty in causal analyses than the...

The audit policy of a tax authority can signal its audit effectiveness. We model this process and show that in limited circumstances an ineffective authority can masquerade as being effective. We show that high maximal penalties imply underreporting of income
