Data quality in the Penn World Tables varies systematically across countries that have different growth rates and at different stages of economic development, thus introducing measurement error correlated with variables of economic interest. We explore the seriousness of this problem with three...

This article considers risk measures constructed under a discrete mixture-of-normal distribution on the innovations of a GARCH model with time-varying volatility. The authors use an approach based on a continuous empirical characteristic function to estimate the parameters of the model using...

This paper extends the multiscale stochastic volatility (MSSV) models to allow for heavy tails of the marginal distribution of the asset returns and correlation between the innovation of the mean equation and the innovations of the latent factor processes. Novel algorithms of Markov Chain Monte...
