Empirically, we show that the proportion of stocks exhibiting conditional heteroscedastic residuals, is high. We suggested to use the market model with GARCH(1,1) residuals in order to describe daily stock returns and derived a test statistics for the null hypothesis of no abnormal returns,...

This paper tests the co-terminal swap market model (SMM) pricing and hedging performance onBermudan swaptions. To our knowledge, the drift for SMM is derived explicitly for the first timehere, and the procedures for calibration and simulation using a collection of forward swap rates arealso...

The well-known absence-of-arbitrage condition NFLVR from the fundamentaltheorem of asset pricing splits into two conditions, called NA and NUPBR.We give a literature overview of several equivalent reformulations of NUPBR;these include existence of a growth-optimal portfolio, existence of the...

There is ample evidence that women do not react to competition as mendo and are less willing to enter a competition than men (e.g., Gneezy et al.(2003), Niederle and Vesterlund (2007)). In this paper, we use personalityvariables toto understand the underlying motives of women (and men) toenter a...
