Increased health care spending has been argued to be largely due to technological change. Cost-effectiveness analysis is the main tool used by private and public third-party payers to prioritize adoption of the new technologies responsible for this growth. However, such analysis by payers...

The world-wide and ongoing rise in obesity has generated enormous popular interest and policy concern in developing countries, where it is rapidly becoming the major public health problem facing such nations. As a consequence, there has been a rapidly growing field of economic analysis of the...

Medical care at the end of life, which is often is estimated to contribute up to a quarter of US health care spending, often encounters skepticism from payers and policy makers who question its high cost and often minimal health benefits. It seems generally agreed upon that medical resources are...

The classic theory of moral hazard concerns the insurance of a single good and predicts that co-insurance is larger when the elasticity of demand is higher and when small risks are insured. We extend this analysis to the insurance of multiple goods; for example, the simultaneous insurance of...

Patent protection spurs innovation by raising the rewards for research, but it usually results in less desirable allocations after the innovation has been discovered. In effect, patents reward inventors with inefficient monopoly power. However, previous analysis of intellectual property has...

Traditional economic analysis has proposed well known remedies to deal with consumption externalities and inefficient technological change in isolation, but lacks a general framework for addressing them jointly. We argue that the joint determination of R&D and consumption externalities is...

This paper provides a theoretical and empirical examination of the long-run growth in weight over time. We argue that technological change has induced weight growth by making home- and market-production more sedentary and by lowering food prices through agricultural innovation. We analyze how...

This paper analyzes how markets for old-age care respond to the aging of populations. We consider how the biological forces, which govern the stocks of frail and healthy persons in a population, interact with economic forces, which govern the demand for and supply of care. We argue that aging...

This paper analyzes how markets for old-age care respond to the aging of populations. We consider how the biological forces, which govern the stocks of frail and healthy persons in a population, interacct with economic forces, which govern the demand and suppoly for labor-intensive care. Many...

Industries in which private nonprofit production is present and significant, such as health care and education, account for more than one-fifth of US economic activity. This paper argues that previous analysis of nonprofits has not separated profit-deviating preferences from the state-defined...
