In this paper we study Norwegian rights issues with focus on the announcement effects of raising seasoned equity. The abnormal returns at announcement in Norway are around −8% to −10% for rights issues, and this is much higher than what is found in other countries. The average...

Cooper and Nyborg (2008) derive a tax-adjusted discount rate formula under a constant proportion leverage policy, investor taxes and risky debt. However, their analysis assumes zero recovery in default. We extend their framework to allow for positive recovery rates. We also allow for differences...

Bitcoin is an open source peer-to-peer electronic money and payment system. It is traded at several exchanges and high-frequency trade data are publicly available. We study the contributions of Bitcoin exchanges to price discovery. Our results show that Mt.Gox and BTC-e are the market leaders...

In this paper we study implied and realized volatility for the Nordic power forward market. We create an implied volatility index with a fixed time to maturity. This index is compared to a realized volatility time series calculated from high-frequency data. The results show that the implied...

Volatility is not directly observable and must be estimated. Estimator based on daily close data is imprecise. Range-based volatility estimators provide significantly more precision, but still remain noisy volatility estimates, something that is sometimes forgotten when these estimators are used...

However, their analysis assumes zero recovery in default. We extend their framework to allow for positive recovery rates. We also allow for differences...

We study multiunit uniform price auctions where the seller is allowed to decrease the quantity supplied in order to maximize his profit. We show that he never chooses to do so in equilibrium. However, the existence of this option eliminates such equilibria where objects for sale are sold for too...
