Without an international climate agreement, extraction of more natural gas could reduce emissions of CO2 as more “clean” natural gas may drive out “dirty” coal and oil. Using a computable equilibrium model for the Western European electricity and natural gas markets, we examine whether...

Using a computable equilibrium model, we examine the short-run effects of a radical liberalisation of the West European natural gas and electricity markets. In each model country, oil, gas, coal and electricity are produced, traded and consumed. There are world markets for oil and coal, and...

The European Union has introduced directives that aim to liberalize and integrate electricity and gas markets in Western Europe. While progress has been made, particularly in electricity markets, there have been setbacks: for example, because of concerns about national interests and security of...

Climate mitigation policy should be imposed over a long period, and spur development of new technologies in order to make stabilization of green house gas concentrations economically feasible. The government may announce current and future policy packages that stimulate current R&D in...

We report evidence from a laboratory experiment comparing contributions in public good games played as individuals to contributions made as group representatives. We find that women alter their behaviour more than men. The change is in an out-group friendly direction: while men's contributions...

Efficiency analyses in the health care sector are often criticised for not incorporating quality variables. The definition of quality of primary health care has many aspects, and it is inevitably also a question of the patients’ perception of the services received. This paper uses variables...

The contributions of the paper are threefold: i) compare with mathematical rigour the Charnes, Cooper, and Rhodes DEA model and the Farrell model exhibiting constant returns to scale, ii) reinterpret the contribution of Farrell and Fieldhouse that extended the analysis to variables returns to...

The performance of local tax offices of Norway is studied over a three year period applying Data Envelopment Efficiency analysis and a Malmquist productivity index. The estimates are biascorrected using a bootstrap approach recently developed for DEA models. The results show that bias correction...

The statistical properties of the efficiency estimators based on Data Envelopment Analysis (DEA) are largely unknown. Recent work by Simar et al. and Banker has shown the consistency of the DEA estimators under specific assumptions, and Banker proposes asymptotic tests of whether two subsamples...

The performance of local tax offices of Norway is studied over a three-year period using Data Envelopment Efficiency analysis and calculating Malmquist productivity indices. One input, labour, is used, and six output categories of the main service activities carried out by tax offices are...
