ECONOMICS: 'To Your Health' Is More Than a Toast to Economists.
Whereas growth accountants use standard monetary measures of return on investment to estimate information technology's impact on productivity, those who study the country's $45 billion annual investment in biomedicine tend to talk instead about "the social rate of return." In health, they argue, the coin of the realm is having a longer, more comfortable life. Two reports released last May conclude that this return is huge-in some cases, more than $20 for every dollar invested.
