Does size matter? Implications of household size for economic growth and convergence
(2018) Prettner, Klaus; Geloso, Vincent; Kufenko, Vadim
We assess the effects of changes in household size on the long-run evolution of living standards and on cross-country convergence. When the observed changes in average household size across countries are taken into consideration, growth in living standards is slower throughout the 20th century as compared to a measure based on per capita GDP. Furthermore, the speed of divergence between different countries be- fore 1950 is faster and the speed of convergence after 1950 is slower after adjusting for the evolution in household size.
Endogenous life expectancy and R&D-based economic growth
(2021) Tscheuschner, Paul
We propose an overlapping generations framework in which life expectancyis determined endogenously by governmental health investments. As a nov-elty, we are able to examine the feedback effects between life expectancy andR&D-driven economic growth for the transitional dynamics. We find that i)higher survival induces economic growth through higher savings and higherlabor force participation; ii) longevity-induced reductions in fertility hampereconomic development; iii) the positive life expectancy effects of larger savingsand higher labor force participation outweigh the negative effect of a reductionin fertility, and iv) there exists a growth-maximizing size of the health caresector that might lie beyond what is observed in most countries. Altogether,the results support a rather optimistic view on the relationship between lifeexpectancy and economic growth and contribute to the debate surroundingrising health shares and economic development.
Longevity-induced vertical innovation and the tradeoff between life and growth
(2017) Baldanzi, Annarita; Prettner, Klaus; Tscheuschner, Paul
We analyze the economic growth effects of rising longevity in a framework of endogenous growth driven by quality-improving innovations. We show that a rise in longevity raises savings and thereby reduces the market interest rate. Since the monopoly profits generated by a successful innovation are discounted by the endogenous market interest rate, this raises the net present value of innovations, which, in turn, fosters R&D. The associated increase in the employment of scientists leads to faster technological progress and a higher long-run economic growth rate. From a welfare perspective, we show that the direct effect of an increase in life expectancy on lifetime utility is much larger than the indirect effect of the induced higher consumption due to faster economic growth. Consequently, the debate on rising health care expenditures should not predominantly be based on the growth effects of health care.
