The authors examine whether volatility risk is a priced risk factor in securities returns. Zero‐beta at‐the‐money straddle returns of the S&P 500 index are used to measure volatility risk. It is demonstrated that volatility risk captures time variation in the stochastic discount factor....

We analyze the problem of pricing and hedging contingent claims in the multi-period, discrete time, discrete state case using the concept of a "[lambda] gain-loss ratio opportunity". Pricing results somewhat different from, but reminiscent of, the arbitrage pricing theorems of mathematical...

This study examines the impact of foreign currency market interventions of the Central Bank of Turkey (CBT) in a multivariate GARCH framework. CBT has switched to the floating exchange rate regime since 2001 crisis and announced that the interventions in the foreign exchange markets are aimed at...

This paper examines the impact of macroeconomic announcements on the high-frequency behavior of the observed implied volatility skew of S&P 500 index options and VIX. We document that macroeconomic announcements affect VIX significantly and slope at a lesser extent. We also find evidence that...

In this paper we present a method for solving the multifirm stochastic growth model of Brock (1979). After obtaining a solution to the growth model, we derive a solution to the asset pricing model of brock (1982) using the duality between the two models.

In this study, we address whether the degree of financial liberalization affects the aggregated total volatility of stock returns by considering the time-varying nature of financial liberalization. We also explore channels through which the degree of financial liberalization impacts aggregated...
