The personalities of central bankers moved center stage during the recent financial crisis. Some central bankers even gained "superstar" status. In this paper, we evaluate the pivotal role of superstar central bankers by assessing the difference an outstanding governor makes to economic...

Despite negative experiences with auctioning off subsidies for renewable energy in some countries, tenders are increasingly used today. We develop a reverse auction which accounts for particularities of intermittent renewable energy sources. Determining the quantity, demanded by the regulator,...

We analyze a drastic price increase in the German auction market for reserve power, which did not appear to be driven by increased costs. Studying the market structure and individual bidding strategies, we find evidence for collusive behavior in an environment with repeated auctions, pivotal...

Due to an ongoing energy transition, electricity networks are increasingly challenged by situations where local electrical power demands are high but local generation is low and vice versa. This finally leads to a growing number of technical problems. To solve these problems in the short-term,...

We examine monetary and fiscal interactions in a monetary union model with uncertainty due to imperfect central bank transparency. It is first shown that monetary uncertainty discourages excessive taxation and may thus reduce average inflation and output distortions. However, as countries enter...

We explain changes in the federal funds target rate using macroeconomic variables and Federal Open Market Committee (FOMC) communication indicators. Econometrically, we employ an ordered probit model of a Taylor rule to predict 75 target rate decisions between 1998 and 2006. We find, first, that...

We explain changes in the Canadian target rate using macroeconomic variables and Bank of Canada (BOC) communication indicators. Econometrically, we employ an ordered probit model of a Taylor rule to predict 60 target rate decisions between 1998 and 2006. We find that BOC communication is...

In this paper, we study the influence of central bank transparency and informal central bank communication on the money market adjustment process between two interest rate decisions. The sample covers nine major central banks for the period from January 1999 to July 2007. We find, first, that...

This paper studies whether the observed high correlation between monetary policy in the U.S. and the Euro area can be explained by economic fundamentals, i.e. by macroeconomic interdependence between the two regions. We show that an optimal monetary policy reaction function for the ECB that...

Using a GARCH model, we analyze the influence of U.S. monetary policy action and communication on the price volatility of commodities for the period 1998-2009. We find, first, that U.S. monetary policy events have an economically significant impact on price volatility. Second, expected target...
