Additional Empirical Evidence on Real Convergence: A Fractionally Integrated Approach

We examine the real convergence hypothesis for 14 OECD countries looking at the fractional order of integration of the differences of real GDP per capita in these countries with respect to the United States. Using parametric procedures, the results vary depending on how we specify the I(0) disturbances. If they are white noise, convergence is achieved for Canada and Australia, and with autocorrelated disturbances, this hypothesis is satisfied for France and the Netherlands. However, allowing for a break at World War II, evidence of convergence is obtained for all countries. JEL no. C32, O41     

Effect of Stress on Later-Life Health: Evidence from the Vietnam War Draft

This article contributes to the literature examining how stress during the early stages of life impacts later-life health using a novel proxy for stress: risk of military induction during the Vietnam War. The article estimates that an increase in induction risk in young adulthood is associated with higher rates of obesity, endocrine disease, and hypertension later in life. These findings do not appear to be cohort effects; these associations exist only for men who did not serve in the war, not for same-aged women. These results suggest stress experienced during early adulthood can have adverse health consequences later in life.
