Though economists assume that intertemporal preferences are time-consistent, evidence suggests that a person's relative preference for well-being at an earlier moment over a later moment increases as the earlier moment gets closer. We explore the beh avioral and welfare implications of such...

In active investment climates where firms sequentially improve each other's products, a patent can terminate either because it expires or because a noninfringing innovation displaces it in the market. The patent breadth and patent life together determine which of these occurs first. We...
