We investigate whether the daily betas of individual stocks vary with the release of firm-specific news in an emerging market. Using intraday prices of all stocks traded on the Borsa Istanbul, Turkey over the period 2005-2013, we find evidence that average market betas increase significantly...

Using novel data from executive deferred compensation, this paper presents new evidence on the relationship between CEO risk preference and firm risk (the volatility of firm performance measures such as stock return, earnings and operating cash flows). My results show a negative association...

In this paper we investigate how privatization affects stock return volatility. We show that privatization is related to volatility via political risk. In particular, a privatization program that is maintained over time signals credibility, which reduces political risk and in turn volatility. We...

Within the structural approach for credit risk models we discuss the optimal exercise of the callable and convertible bonds. The Vasiček-model is applied to incorporate interest rate risk into the firm’s value process which follows a geometric Brownian motion. Finally, we derive pricing...

Within a default intensity approach we discuss the optimal exercise of the callable and convertible bonds. Pricing bounds for convertible bonds are derived in an uncertain volatility model, i.e. when the volatility of the stock price process lies between two extreme values.

In this paper, we show that in a model where investors have heterogeneous preferences, the expected return of risky assets depends on the idiosyncratic coskewness beta, which measures the co-movement of the individual stock variance and the market return. We find that there is a negative...

We develop a model of investment, payout, and financing policies in which firms face uncertainty regarding their ability to raise funds and have to search for investors when in need of capital. We show that capital supply uncertainty leads firms to value financial slack and to adjust their...
