e develop a model of regime-switching risk premia as well as regimedependent factor risk premia to price real options. The model incorporates the observation that the underlying risky income streams of real options are subject to discrete shifts over time as well as random changes. The presence...

We extend a target zone model to allow for occasional changes in the policy regime which change the stochastic process driving fundamentals. A scenario we have in mind is that macroeconomic policy alternates between relatively tight and loose regimes. A key implication of our analysis is that...

We examine several discrete-time term-structure models, in which the short rate is subject to discrete shifts. Our empirical analysis suggests that inquiring which parameters of the short-term interest rate equation are allowed to switch is crucial. Failing to do so may result in switching...

This paper proposes a contemporaneous-threshold smooth transition GARCH (or CSTGARCH) model for dynamic conditional heteroskedasticity. The C-STGARCH model is a generalization to second conditional moments of the contemporaneous smooth transition threshold autoregressive model of Dueker et al....

The empirical relationship between money and output is one of the most studied issues in macroeconomics, and a large literature has examined the causal links between monetary variables and output. One puzzle from this literature is that the results of causality tests appear to be sensitive with...

This paper tests the properties of the zloty-dollar exchange rate for the possible presence of unknown non-linearities. It concludes that there is strong evidence for the presence of an underlying non-linear process which is possibly chaotic. A non-linear model which allows for discrete...

This paper demonstrates, by means of Monte Carlo experimentation, that tests of the expectations hypothesis of the term structure based on instrumental variables regressions of the change in the short rate on the relevant lagged yield spread are prone to severe over-rejection when the term...

We develop and apply a method of testing for speculative bubbles. The method is designed to overcome two well-known problems in the identification of bubble phenomena--the problem of distinguishing any type of bubble from an expected future change in market fundamentals and the problem of...
