Northern trade liberalization reduces the rate of innovation, increases Northern unemployment, and reduces both Northern and … Southern per-capita welfare. The effects are reversed in the case of unilateral Southern trade liberalization. Hence, wage …

This paper analyzes the optimal protection strategy for an innovator of a complex innovation who faces the risk of … imitation by a competitor. We suppose that the innovation can be continuously fragmented into sub-innovations. We characterize … the optimal mix of patent and trade secrets when the innovator faces a strict novelty requirement and can only patent a …
