This paper compares the fitting of the normal, generalized hyperbolic, normal inverse Gaussian and Student t distributions to the daily returns of the Portuguese Stock Index PSI-20 over the period 1992-2013. We find that the distribution of the actual returns of the PSI-20 exhibits much higher...

The future evolution of energy supply technologies strongly depends on (and affects) the economic and environmental systems, due to the high dependency of this sector on the availability and cost of fossil fuels, especially on the small regional scale. This paper aims at presenting the modeling...

Nowadays, many countries adopt an active agenda to mitigate the impact of greenhouse gas emissions by moving towards less polluting energy generation technologies. The environmental costs, directly or indirectly generated to achieve such a challenging objective, remain however largely...

This paper analysis the welfare changes arising from a road project, undertaken as a public-private partnership, measured as the variation in utility, using a sequentially dynamic general equilibrium model. To circumvent the budget restriction imposed by the central government, the Azorean...
