This paper re-considers the importance of trade openness for equilibrium determinacy when monetary policy is characterized by interest-rate rules. We develop a two-country, sticky-price model where money enters the utility function in a non-separable manner. Forward- and current-looking policy...

This paper investigates the conditions under which interest-rate rules induce real equilibrium indeterminacy in a two-country, sticky-price, monetary model. Using a discrete-time framework, we employ the two most commonly used timing assumptions on which money balances enter into the utility...

This paper presents a two-country sticky-price model that allows for capital and investment spending. It analyzes the conditions for equilibrium determinacy under alternative interest-rate rules that react to either domestic or consumer price inflation. It is shown that in the presence of...

In this paper we test for the presence of periodically partially collapsing, positive and negative, speculative bubbles in the S&P 500 Composite Index for the period 1888-2001. We extend existing regime-switching models of speculative behaviour by including abnormal volume as an indicator of the...

This study tests for the presence of periodically, partially collapsing speculative bubbles in the sector indices of the S&P 500 using a regime-switching approach. We also employ an augmented model that includes trading volume as a technical indicator to improve the ability of the model to time...

This paper explores the properties of a European spread option valuation method for correlated assets when the marginal distribution each asset return is assumed to be a mixture of normal distributions. In this ‘bivariate normal mixture’ (BNM) approach no-arbitrage option values are just...

In this paper we examine whether a three-regime model that allows for dormant, explosive and collapsing speculative behaviour can explain the dynamics of the S&P 500 Composite Index for the period 1888-2001. We extend existing two-regime models of speculative behaviour by including a third...

historical forward rates are used to calibrate the lognormal forward rate model - as advocated by Hull and White (1999, 2000), Longstaff, Santa Clara and Schwartz (1999), Rebonato (1999a,b,c), Rebonato and Joshi (2001) and many others - a Libor yield curve needs to be fit to the available data...

Recent research has discussed the possible role of unsystematic risk in explaining equity returns. Simultaneously, but somehow independently, numerous other studies have documented the failure of the static and conditional capital asset pricing models to explain the differences in returns...
