Providing a good formulation is an important part of solving a mixed integer program.We suggest to measure the quality of a formulation by whether it is possible tostrengthen the coefficients of the formulation. Sequentially strengthening coefficientscan then be used as a tool for improving...

This paper discusses the theoretical and practical aspects of new methods for solving DEA problems under real-life geometrical uncertainty and probability uncertainty of sample data. The proposed minimax approach to solve problems with geometrical uncertainty of sample data involves an...

We study a model of managerial incentive problems where a manager chooses the first two moments of his firm's profit distribution - mean and volatility - along an efficient frontier. Assuming that managers differ with respect to their marginal cost of effort and their risk aversion we explore...

We propose a novel approach to deal with the problem of indeterminacy in Linear Rational Expectations models. The method consists of augmenting the original model with a set of auxiliary exogenous equations that are used to provide the adequate number of explosive roots in presence of...
