We study the nonparametric identification of distributions of utility functions in a multiple purchase setting with a finite number of consumers. Each utility function takes as arguments subsets or, alternatively, quantities of the multiple goods. We exploit mathematical insights from auction...

Consider an economy in which a fi…xed supply of unskilled labor can be combined with knowledge capital to produce consumption. The technology for accumulating knowledge capital is linear in knowledge capital. This leads to long-term growth if the production function for consumption goods is...

It is proved for two-player normal form games that if a totally mixed Nash equilibrium exists then the entire set of Nash equilibria is (trembling-hand) perfect. More generally, it is proved that if there is a (trembling-hand) perfect equilibrium, then all Nash equilibria whose supports are...

I present an example showing it is sometimes efficient for a bank to commit to a policy that keeps information about its risky assets private. Current practices in banking result in bankers having private information: demand deposits are non-contingent contracts, there are time lags before the...

We describe two-person simultaneous play games. First, we use a zero sum game to illustrate minimax, dominant and best response strategies. We illustrate Nash Equilbria in the Prisoner's Dilemma and the Battle of the Sexes Game, and distinguish three types of Nash Equilibria: a pure strategy, a...

Although employment at individual firms tends to be highly non-stationary, the employment size distribution of all firms in the United States appears to be stationary. It closely resembles a Pareto distribution. There is a lot of entry and exit, mostly of small firms. This paper surveys general...
