An alternative condition, called reduction invariance, is given to derive Prelec's (1998) form for the weighting function in separable utility theory. The condition, which is a variant on the reduction of compound gambles, is appreciably simpler and more empirically testable than Prelec's...

The purpose of this paper is to define the concept of expected minimum cost function and to present the methodology for a non parametric estimation of it. Generally, in cost enonometric analysis, inference is made on the cost function, namely the conditional expectation of cost given some level...

This survey presents cutting planes that are useful or potentially useful in solving mixed integer programs. Valid inequalities for i) general integer programs, ii) problems with local structure such as knapsack constraints, and iii) problems with 0-1 coefficient matrices, such as set packing,...

A new model for the analysis of durations, the stochastic conditional dusration (SCD) model is introduced. This model is based on the assumption that the durations are generated by a latent stochastic factor that follows a first order autoregressive process. The lattent factor is perturbed...

We find a condition for the normalized sequence of independent and identically distriubted random nuclear operators to satisfy the Central Limit Theorem.
