In this paper we introduce a discrete time pricing model for a European call option when the log-return of the underlying stock (asset) is subject to discontinuous market regime type of shifts in its mean or volatility whose risk can be priced in the market. The paper shows how to estimate this...

This paper presents a new stochastic volatility model which allows for persistent shifts in volatility of stock market returns, referred to as structural breaks. These shifts are endogenously driven by large return shocks (innovations), reflecting large pieces of market news. These shocks are...

This paper provides clear cut evidence that the slope and curvature factors of the yield curve contain more information about future changes in economic activity than the term spread alone, often used in practice as an indicator of future economic conditions. These two factors constitute...

This paper suggests term spread regression based tests allowing for time-varying term premium effects, with the aim of explaining the empirical failures of the term spread to forecast future movements in interest rates. To capture the e¤ects of a time-varying term premium on the term spread,...

This paper suggests an affine term structure model of real interest rates to predict changes in real consumption growth. The model is estimated, jointly, by real interest rates and consumption data, and it is found to be consistent with the consumption smoothing hypothesis. The paper shows that...

This paper employes a parametric model of structural breaks in the mean of stock returns which allows them to be endogenously driven by large positive or negative stock market return shocks. These shocks can be taken to reflect important market announcements, monetary policy regime shifts and/or...
