摘要：We investigate the evolution of global welfare in two dimensions: income per capita
and life expectancy. First, we estimate the marginal distributions of income and life ex-
pectancy separately. More importantly, in contrast to previous univariate approaches,
we consider income and life expectancy jointly and estimate their bivariate global dis-
tribution for 137 countries during 1970 - 2000. We reach several conclusions: the global
joint distribution has evolved from a bimodal into a unimodal one, the evolution of
the health distribution has preceded that of income, global inequality and poverty has
decreased over time and the evolution of the global distribution has been welfare im-
proving. Our decomposition of overall welfare indicates that global inequality would
be underestimated if within-country inequality is not taken into account. Moreover,
global inequality and poverty would be substantially underestimated if the dependence
between the income and health distributions is ignored.
