The high-frequency measures tend to be positively correlated. Posted spreads and effective costs are very highly correlated. Price impact measures and other statistics derived from dynamic models, however, are only modestly...

BACKGROUND A new health care technology must be cost-effective in order to be adopted. If evidence regarding cost-effectiveness is uncertain, then the decision maker faces two choices: (1) adopt the technology and run the risk that it is less effective in actual practice, or (2) reject the technology and risk that potential health is forgone.
