Effects of national energy policies on carbon dioxide emissions in a European internal electricity market: Results from a simulation model of the European power systems

Hoster, Frank - 1997

This article considers the economic and environmental (in terms of CO2) effects of national energy policies in a European Single Market for electricity. It was found that the combined CO2/Energy-tax proposed by the European Commission would be able to stabilise the current volume of...

A General Equilibrium Analysis of the Evolution of the Canadian Service Productivity

Mohnen, Pierre; Raa, Thijs Ten - Centre Interuniversitaire de Recherche en Analyse des … - 1997

This paper measures factor productivities (and hence total factor productivity growth) directly on the basis of the fundamentals of the economy (endowments, preferences and technology), without recourse to market prices. The factor productivities are the Lagrange multipliers of a linear program...

New variants of finite criss-cross pivot algorithms for linear programming

Zhang, S. - Erasmus University Rotterdam, Econometric Institute - 1997

In this paper we generalize the so-called first-in-last-out pivot rule and the most-often-selected-variable pivot rule for the simplex method, as proposed in Zhang \cite{Z91}, to the criss-cross pivot setting where neither the primal nor the dual feasibility is preserved. The finiteness of the...

Analytic central path, sensitivity analysis and parametric linear programming

Holder, A. G.; Sturm, Jos F.; Zhang, Shuzhong - 1997

parametric linear programming. We first show that if the right-hand sidevector of a standard linear program is perturbed, then …

Alternative Approaches to Estimate Returns to Scale in DEA- Models

Löthgren, Mickael; Tambour, Magnus - Economics Institute for Research (SIR), … - 1996

This paper presents a number of approaches to estimate returns to scale properties of general multiple-input muliple-output technologies. Both qualitative scale efficiency-properties and quantitative scale elasticity-properties are covered. The estimation approaches considered are based on data...
