This paper examines the welfare-maximizing degree of patent protection in a growth model where the engines of economic growth are R&D and public services. We find that an increase in public services enhances the positive and negative effects of strengthening patent protection on R&D and the...

The growth effects of intellectual property right (IPR) protection are examined in a quality-ladder model of endogenous growth. Stronger IPR protection, which reduces the probability of imitation, raises the reward for innovation. However, stronger protection reduces the number of competitive...

This paper examines the growth effects of intellectual property right (IPR) protection in a quality-ladder model of endogenous growth. Stronger IPR protection, which reduces the imitation probability, increases the reward for innovation. However, stronger protection also gradually reduces the...

This paper investigates the sustainability and welfare effects of government budget deficits by using a simple endogenous growth model with overlapping generations. It is shown that, if the initial volume of government debt and the ratio of primary budget deficits to GDP are not large, then...
