Taxation, bubbles and endogenous growth

We study the interplay between taxation, bubble formation and economic growth. A rational bubble may be beneficial when growth is fueled by public investment (or R&D externalities) and the government levies taxes on bubble returns to finance this investment. Our main result challenges the conventional view about the negative effect of bubbles in endogenous growth (Grossman and Yanagawa, 1993).
