This paper illustrates how the use of random set theory can benefit partial identification analysis. We revisit the origins of Manski’s work in partial identification (e.g., Manski (1989, 1990)) focusing our discussion on identification of probability distributions and conditional expectations...

Using data on local exchange carriers (LECs), I estimate the total cost function of LECs operating between 1988 and 1995. First, I show that cost complementarities can be nonparametrically identified in many situations where economies of scope and subadditivity—the focus of previous empirical...

Most of the existing literature on the optimal shape of income tax has a common result - decreasing marginal tax rates. This result stands in sharp contrast with real world income tax systems that are characterized by increasing marginal tax rates. Diamond (1998) made explicit the factors that...
