This paper reviews the empirical literature on rates of return on R&D and interprets the economic significance of these estimates using a semi-endogenous growth model with a calibrated knowledge production sector. We analyse how R&D subsidies, a reduction of entry barriers for start-ups and...

We consider an endogenous growth model with Blanchard-Yaari-type overlapping generations that is built around four sectors: final and intermediate goods production, an R&D sector and a health care sector. Health care serves to lower mortality and morbidity, the latter being related to...

We study the effects of a labor-intensive health care sector within an R&D-driven growth model with overlapping generations. Health care increases longevity and labor participation/productivity. We examine under which conditions expanding health care enhances growth and welfare. Even if the...

This paper takes a fresh look at three issues in the aid effectiveness debate. First, we assess the theoretical case for foreign aid. Using an endogenous growth version of the standard overlapping generations model, we show that aid can be an effective policy tool in spurring growth in poor...

What happens if HIPC debt relief resources are not additional? We seek to answer this question by quantifying the impact of debt service payments and aid flows in cross- country growth and investment regressions . Based on the regressions we assess the likely impact of debt relief with and...

This paper examines the relationship between foreign aid and growth in real GDP per capita as it emerges from simple augmentations of popular cross-country growth specifications. It is shown that aid in all likelihood increases the growth rate, and this result is not conditional on "good"...
