Antitrust analysis conventionally assumes that illegal agreements among competitors raise prices and lower quantities, relative to lawful competition. However, markets for healthcare services have tendencies towards overprovision, which may increase when competition declines. This paper examines...

In calculating damages in healthcare antitrust cases, the difference-in-difference (DID) approach provides a potentially valuable means of controlling for lawful factors that influence prices, such as case-mix and quality of care, as distinct from price differentials due to unlawful behavior....

In considering whether asset-price bubbles should be offset through policy, an important issue is who pays the price when the bubble bursts. A bust that reduces the wealth of well-off households only may have small welfare costs, but costs may be sizable if broad swaths of households are...

After the bursting of the housing-price bubble in 2006 and ensuing financial crisis, there has been much discussion of what economists could have done differently to help avert the crisis and "Great Recession" that followed. One dimension of this concerns information supplied by economists to...
