In many empirical studies, both spot and futures prices were shown to contain a stochastic trend. Consequently, it is necessary to examine the possible cointegration relationship between the two prices as suggested by the efficient markets hypothesis. The importance of incorporating the cointegratio

Abstract
Utilizing a panel data set of 50 US states, this note investigates nonstationarity and cointegration of health care expenditures and gross state products (GSP). Both the individual stateβbased method and the recent panel data method are applied. Allowing for structural breaks in the test, we find that health care expenditures and GSP are both nonstationary. The evidence also suggests that the two series form a cointegrating relationship. The income elasticities of health spending vary over states and became smaller in the 1990s.

## Abstract The relative income hypothesis, that relative income has a direct effect on individual health, has become an important part of the literature on health inequalities. This paper presents a fourβquadrant diagram, which shows the effect of income, relative income and aggregation bias on in
## Abstract We use the core interviews of the US Health Interview Survey for the years 1987β1994, to study the effects of socioeconomic status (SES) on mortality and selfβreported health. We find, consistent with previous studies, that the relationship between mortality and indicators such as educa
This paper studies the relationship between health care expenditure (HCE) and age, using longitudinal rather than cross-sectional data. The econometric analysis of HCE in the last eight quarters of life of individuals who died during the period 1983-1992 indicates that HCE depends on remaining lifet
