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...

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...
