A positive relationship between socio-economic status (SES) and health, the so-called "health-wealth gradient", is repeatedly found in most industrialized countries with similar levels of health care technology and economic welfare. This study analyzes causality from health to wealth (health...

We study the labor supply dynamics of elderly couples by means of a structural collective model. The model allows for general externalities with respect to spouses' leisure. Preferences and the intrahousehold bargaining process are identified by using panel data with couples and individuals who...

The public economic burden of shifting trends in population health remains uncertain. Sustained increases in obesity, diabetes, and other diseases could reduce life expectancy - with a concomitant decrease in the public-sector's annuity burden - but these savings may be offset by worsening...

We use a calibrated stochastic life-cycle model of endogenous health spending, asset accumulation and retirement to investigate the causes behind the increase in health spending and life expectancy over the period 1965-2005. We estimate that technological change along with the increase in the...

The standard model of intertemporal choice assumes risk neutrality toward the length of life: due to additivity, agents are not sensitive to a mean preserving spread in the length of life. Using a survey fielded in the RAND American Life Panel (ALP), this paper provides empirical evidence on...

We look at the effect of the 2000 repeal of the earnings test above the normal retirement age (NRA) on retirement expectations of male workers in the Health and Retirement Study (HRS). Using administrative records on Social Security benefit entitlements linked to the HRS survey data, we can...

We study the effects of liquidity constraints and start-up costs on the relationship between wealth and the fraction of entrepreneurs in an economy. We develop a dynamic occupational choice model with endogenous wealth and entry into entrepreneurship. The model predicts that, with liquidity...

We provide comparable evidence on the patterns and trends in obesity across the Atlantic and analyse whether there are economic rationales for public intervention to control obesity. We take into account equity issues as well as efficiency considerations, which are organized around three...

In 1975, 50 year-old Americans could expect to live slightly longer than their European counterparts. By 2005, American life expectancy at that age has diverged substantially compared to Europe. We find that this growing longevity gap is primarily the symptom of real declines in the health of...
