This paper considers the problem of forecasting under continuous and discrete structural breaks and proposes weighting … only across regimes. In practice, where information on structural breaks is uncertain, a forecasting procedure based on … experiments and an empirical application to forecasting real GDP using the yield curve across nine industrial economies. …

We propose a Bayesian nonparametric model to estimate rating migration matrices and default probabilities using the reinforced urn processes (RUP) introduced in Muliere et al. (2000). The estimated default probability becomes our prior information in a parametric model for the prediction of the...

We introduce a new class of models that has both stochastic volatility and moving average errors, where the conditional mean has a state space representation. Having a moving average component, however, means that the errors in the measurement equation are no longer serially independent, and...

The ranking of multivariate volatility models is inherently problematic because when the unobservable volatility is substituted by a proxy, the ordering implied by a loss function may be biased with respect to the intended one. We point out that the size of the distortion is strictly tied to the...

AR–GARCH type models. We consider tests for the null hypotheses of no linear and quadratic serial residual … we show that, generally, no size correction is needed in the asymptotic test distribution when applied to AR–GARCH …. Simulations show that our asymptotic approximations work well for a large number of AR–GARCH models and parameter values. We also …

When a model under-specifies the data generation process, model selection can improve over estimating a prior specification, especially if location shifts occur. Impulse-indicator saturation (IIS) can ‘correct’ non-constant intercepts induced by location shifts in omitted variables, which...

Estimating the integrated covariance matrix (ICM) from high frequency financial trading data is crucial to reflect the volatilities and covariations of the underlying trading instruments. Such an objective is difficult due to contaminated data with microstructure noises, asynchronous trading...
