Understanding the most important economic impacts of vaccines can provide relevant information to stakeholders when selecting vaccine immunization strategies from a broader perspective. This study was therefore designed to first identify economic impacts to vaccinated individuals and, second, assess the relative importance of these economic impacts. A four-step approach was used, including a re...

The models of microeconomics are famously idealized and have a famously spotty predictive record. Yet recent years have seen some tremendous successes in using these models to construct reliable economic institutions. The focus of this chapter is one such institution, namely, spectrum auctions—now used all over Europe and North America to distribute licenses to telecommunications fi rms. This h...
