This paper studies properties of stochastic objective functions, that is, objective functions which can be written as the expected value of a payoff function.

The paper provides a general analysis of the types of models with E-Perturbations which have been used recently to discuss the evolution of social conventions. Two new measures of the size and structure of the basins of attraction of dynamic systems, the radius and coradius, are introduced in...

Classically, the concept of efficiency measurement is based on the definition of a frontier that envelops the observed production plans. The efficiency score itself is based on the distance of an observed production plan from this frontier. The frontier along with the required technological...

In this paper we address the issue of the efficient estimation of the cointegrating vector in linear regression models with variables that follow general (higher order and fractionally) integrated processes.
