Another approach for estimating RTS in dynamic DEA

Soleimani-damaneh, M. - In: Journal of Productivity Analysis 39 (2013) 1, pp. 75-81

Recently, in some papers in the field of operations research the performance analysis of decision making units, in the presence of time factor, has been dealt with by an analytical framework of DEA: dynamic DEA. This paper provides a new approach, utilizing the envelopment models, for estimating...

Benefit-of-the-doubt aggregation and the diet problem

Färe, Rolf; Karagiannis, Giannis - In: Omega 47 (2014) C, pp. 33-35

In this note we show that the diet problem and the benefit-of-the-doubt (BoD) aggregation are linear programming duals. That is, the primal (dual) formulation of the diet problem is equivalent to the dual (primal) formulation of the BoD model as long as food prices are set equal to one. In...

Benson type algorithms for linear vector optimization and applications

Hamel, Andreas; Löhne, Andreas; Rudloff, Birgit - In: Journal of Global Optimization 59 (2014) 4, pp. 811-836

New versions and extensions of Benson’s outer approximation algorithm for solving linear vector optimization problems are presented. Primal and dual variants are provided in which only one scalar linear program has to be solved in each iteration rather than two or three as in previous...

Competitive equilibrium with search frictions: Arrow-Debreu meets Diamond-Mortensen-Pisarides

Jerez, Belén - Departamento de Economía, Universidad Carlos III de Madrid - 2010

When the trading process is characterized by search frictions, traders may be rationed so markets need not clear. We argue that rationing can be part of general equilibrium, even if it is outside its normal interpretation. We build a general equilibrium model where the uncertainty arising from...
