Die EEG-Umlage, die Stromverbraucher für die Förderung von Strom aus erneuerbaren Energien zahlen müssen, wird im Jahr 2013 stark steigen. Dadurch erhöht sich der Anteil der Ausgaben für Strom an den Konsumausgaben privater Haushalte von durchschnittlich rund 2,3 Prozent im Jahr 2011 und...

Die Zukunft der deutschen Braunkohle in einer zunehmend von erneuerbaren Energieträgern geprägten Stromwirtschaft wird derzeit kontrovers diskutiert. An allen drei Braunkohlestandorten (Rheinisches, Mitteldeutsches und Lausitzer Revier) gibt es Pläne zum Bau neuer Braunkohlekraftwerke sowie...

Using the maximum likelihood method, in order to estimate Half-Normal stochastic frontier production models, entails several practical di±culties that, perhaps, have not been su±ciently emphasised. In employing FRONTIER software, we analyse the case in which the estimation obtained suggests...

Grey system theory can powerfully deal with incomplete and uncertain information. In this paper, we introduced an improved grey GM(1,1) model that integrates residual modification with Markov chain model. By this model, we improved the forecast accuracy of original grey forecast model and...

The paper intends to measure the daily Value-at-Risk (VaR) for Rial-Euro exchange rate fluctuations risk. Since in this case we deal with a single risk factor, so we will not use the Monte Carlo simulation method to measure the VaR and we will only use the parametric and historical simulation...

Insurance companies have to estimate reserves and provisions to cover the payment of either unreported claims or unsettled claims. In this paper, we apply the Chain-Ladder method to obtain a point estimate of reserves, and then we use the bootstrap technique to estimate the margin of error and...

In some circumstances a decision maker, expert, in a group decision making problem cannot express his/her preferences with a unique linguistic fuzzy preference because he/she is dubious into some preferences. In this paper, we present a consensus model for group decision making problems with...
