This paper studies models where the correspondences (or functions) under consideration are never increasing (or weakly decreasing) in endogenous variables, and weakly increasing in exogenous parameters. Such models include games of strategic substitutes, and include cases where additionally,...

Nash equilibria are defined using uncorrelated behavioural or mixed joint probability distributions effectively assuming that players of bounded rationality must discard information to locate equilibria. We propose instead that rational players will use all the information available in...

We propose a decomposition method for the solution of a dynamic portfolio optimization problem which fits the formulation of a multistage stochastic programming problem. The method allows to obtain time and nodal decomposition of the problem in its arborescent formulation applying a discrete...

We give the reader a tour of good energy optimization models that explicitly deal with uncertainty. The uncertainty usually stems from unpredictability of demand and/or prices of energy, or from resource availability and prices. Since most energy investments or operations involve irreversible...

The residential UK electricity market was opened for the first time in 1999, introducing choice of supplier, and about 40% of households changed supplier in the first four years. After three years price caps were removed. We review this process and assess the competitiveness of the market by...

Nigeria is going through a difficult political and economic transition after decades of independence.Yet, Nigeria remains a society rich in cultural, linguistic, religious, ethnic and political diversity. Today, the average Nigerian struggles hard to make ends meet; sees himself or herself as...

The paper speaks of the technological evolution using a translog cost function for a western European country – Portugal. It begins by presenting the methodological framework, the estimation process based on the iterative Zellner method to estimate systems of seemingly unrelated regression...

NIGERIA IS GOING THROUGH A DIFFICULT POLITICAL AND ECONOMIC TRANSITION AFTER FORTY YEARS OF INDEPENDENCE. YET, NIGERIA REMAINS A SOCIETY RICH IN CULTURAL, LINGUISTIC, RELIGIOUS, ETHNIC AND POLITICAL DIVERSITY. TODAY, THE AVERAGE NIGERIAN STRUGGLES HARD TO MAKE ENDS MEET; SEES HIMSELF OR HERSELF...
