Since Kydland and Prescott published their famous article on rules versus discretion in 1977, the literature on the time-inconsistency problem of economic policy expanded rapidly. While much of the literature is highly technical and can seem esoteric, there is generally an underlying...

This paper reviews selectively the literature on exchange rate target zones and corresponding methodologies and examines whether they can be used to analyse the inflation-control problem. Given the close correspondence between the exchange rate and inflation-targeting problems, the target-zone...

This paper proposes a variant of a threshold stochastic conditional duration (TSCD) model for financial data at the transaction level. It assumes that the innovations of the duration process follow a threshold distribution with a positive support. In addition, it also assumes that the latent...

This paper studies multiscale stochastic volatility models of financial asset returns. It specifies two components in the log-volatility process and allows for leverage/asymmetric effects from both components while return innovation terms follow a heavy/fat tailed Student t distribution. The two...

This paper considers Value at Risk measures constructed under a discrete mixture of normal distribution on the innovations with time-varying volatility, or MN-GARCH, model. We adopt an approach based on the continuous empirical characteristic function to estimate the param eters of the model...

This paper extends the stochastic conditional duration model by imposing mixtures of bivariate normal distributions on the innovations of the observation and latent equations of the duration process. This extension allows the model not only to capture the asymmetric behavior of the expected...
