How important is health inequality for lifetime earnings inequality?

Hosseini, Roozbeh; Kopecky, Karen A.; Zhao, Kai - 2021

Using a dynamic panel approach, we provide empirical evidence that negative health shocks reduce earnings. The effect is primarily driven by the participation margin and is concentrated in less educated individuals and those with poor health. We build a dynamic, general equilibrium, life cycle...

The effects of health shocks on family status: do financial incentives encourage marriage?

Ehlert, Andree - In: The European Journal of Health Economics 22 (2021) 9, pp. 1393-1409

This paper asks whether marriage decisions of unmarried mature couples are driven by the prospect of financial advantages for the later widowed after one partner has suffered a serious health shock. We hypothesize that, in contrast to traditional marriage models, such health shocks may induce...

Life Expectancy at Current Rates vs. Current Conditions

Vaupel, James W. - In: Demographic Research 7 (2002) 8, pp. 365-378

Life expectancy is overestimated if mortality is declining and underestimated if mortality is increasing. This is the fundamental claim made by Bongaarts and Feeney (2002) in their article "How Long Do We Live?", where they base their claim on arguments about "tempo effects on mortality". This...

Parametric frailty and shared frailty survival models

Gutierrez, Roberto G. - In: Stata Journal 2 (2002) 1, pp. 22-44

Frailty models are the survival data analog to regression models, which account for heterogeneity and random effects. A … frailty is a latent multiplicative effect on the hazard function and is assumed to have unit mean and variance theta, which is … estimated along with the other model parameters. A frailty model is an heterogeneity model where the frailties are assumed to be …
