Common negative extreme variations in returns are prevalent in international equity markets. This has been widely documented with statistical tools such as exceedance correlation, extreme value theory, and Gaussian bivariate GARCH or regime-switching models. We point to limits of these tools to...

This paper proposes a new simulation-based approach for optimal portfolio allocation in realistic environments with complex dynamics for the state variables and large numbers of factors and assets. A first illustration involves a choice between equity and cash with nonlinear interest rate and...

The Markov Switching Model, introduced by Hamilton (1988, 1989), has been used in various economic and financial applications where changes in regime play potentially an important role. While estimation methods for these models are by now well established, such is not the case for the...

Incorporating prior knowledge of a particular task into the architecture of a learning algorithm can greatly improve generalization performance. We study here a case where we know that the function to be learned is non-decreasing in its two arguments and convex in one of them. For this purpose...

In this paper, we match both the first and the second moments of the equity premium and the risk-free rate by endowing the agents in the economy with disappointment aversion preferences and by making the joint process of consumption and dividends follow a Hamilton's (1989) Markov switching...

This paper assesses the empirical performance of an intertemporal option pricing model with latent variables which generalizes the Hull-White stochastic volatility formula. Using this generalized formula in an ad-hoc fashion to extract two implicit parameters and forecast next day S&P 500 option...

Latent variable models in finance originate both from asset pricing theory and time series analysis. These two strands of literature appeal to two different concepts of latent structures, which are both useful to reduce the dimension of a statistical model specified for a multivariate time...

The authors develop and estimate an equilibrium-based model of the Canadian term structure of interest rates. The proposed model incorporates a vector-autoregression description of key macroeconomic dynamics and links them to those of the term structure, where identifying restrictions are based...

This paper focuses on whether monetary policy has asymmetric effects. By building on the Markov switching model introduced by Hamilton (1989), we examine questions like: Does monetary policy have the same effect regardless of the current phase of economic fluctuations? Given that the economy is...
