Der Ausstieg aus der Kernenergie und die angestrebte Energiewende werden vermutlich zu steigenden Strompreisen führen. Einigen Schätzungen zufolge könnten die Preise für Strom bis zum Jahr 2020 um bis zu 30% angehoben werden. Wer trägt die Hauptlast der hohen Kosten? Kann es gelingen, die...

Along with the oil price, concerns about the security of energy supply have soared once again in recent years. Yet, more than 30 years after the OPEC oil embargo in 1973, energy security still remains a diffuse concept. This paper conceives a statistical indicator that aims at characterizing the...

The security of energy supply has again become a similarly hot topic as it was during the oil crises in the 1970s, not least due to the recent historical oil price peaks. In this paper, we analyze the energy security situation of the G7 countries using a statistical risk indicator and empirical...

This paper presents evidence that the accumulating cost of Germany’s ambitious plan to transform its system of energy provision – the so-called Energiewende – is butting up against consumers’ willingness-to-pay (WTP) for it. Following a descriptive presentation that traces the German...

Interaction effects capture the impact of one explanatory variable x1 on the marginal effect of another explanatory variable x2. To explore interaction effects, so-called interaction terms x1x2 are typically included in estimation specifications. While in linear models the effect of a marginal...
