Based on the seminal paper of Farrell (1957), researchers have developed several methods for measuring efficiency. Nowadays, the most prominent representatives are nonparametric data envelopment analysis (DEA) and parametric stochastic frontier analysis (SFA), both introduced in the late 1970s....

In certain circumstances, both researchers and policy makers are faced with the challenge of determining individual efficiency scores for each decision making unit (DMU) under consideration. In this study, we use a Monte Carlo experimentation to analyze the optimal approach to determining...

Based on a unique data set of 909 defaulted retail and commercial (self-employed and SMEs) credit customers in Germany, whose original loans were made by 123 different banks, our article confirms a significant positive influence of collateral, and of amicable agreements between the debtor and...

In this article we show how different promotion schemes for renewables affect economic welfare. Our starting point is that external benefits of renewable electricity supply besides the abatement of greenhouse gases are not related to actual electricity generation but to producing and installing...

We derive optimal subsidization of renewable energies in electricity markets. The analysis takes into account that capacity investment must be chosen under uncertainty about demand conditions and capacity availability, and that capacity as well as electricity generation may be sources of...

Die seit Jahren niedrigen Zertifikatspreise werden häufig als Begründung dafür angeführt, dass der EU-Emissionshandel reformiert werden muss. Politisch favorisiert wird aktuell die so genannte Marktstabilitätsreserve: ein regelbasierter Mechanismus, nach dem die Menge an...
