We examine several continuous-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, as failing to do so may result in switching...

We study how entry and exit decisions of a monopolist are affected by business cycle conditions. We model the business cycle as a two-state Markov process, and assume that the demand curve faced by the monopolist evolves differently in the two states of the economy. We explore conditions under...

This paper explores the interactions between cross-sectional aggregation and persistence of volatility shocks. We derive the ARMA-GARCH representation that linear aggregates of ARMA processes with GARCH errors admit, and establish conditions under which persistence in volatility of the aggregate...

We examine several continuous-time term structure models in which the short rate is subject both to continuous changes and to discrete shifts. Several regime-switching term structure models are developed, with regime-dependence in various combinations of their drift and diffusion parameters. We...

This paper considers the problem of estimating Markov regime switching models with endogenous explanatory variables. When the data-generating process for consumption is subject to Markov regime switching, the standard model for the term structure of interest rates based on the Euler equations...

In this paper we examine a model of cointegration where long-run parameters are subject to switching between several different cointegrating regimes. These shifts are allowed to be governed by the outcome of an unobserved Markov chain with unknown transition probabilities. We illustrate this...

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...
