This paper explains how the Gibbs sampler can be used to perform Bayesian inference on GARCH models. Although the Gibbs sampler is usually based on the analyti-cal knowledge of the full conditional posterior densities, such knowledge is not available in regression models with GARCH errors. We...

We provide a detailed discussion of the time series modelling of daily tax revenues. The mainfeature of daily tax revenue series is the pattern within calendar months. Standard seasonal timeseries techniques cannot be used since the number of banking days per calendar month varies andbecause...

The paper deals with a summary of findings in the area of tax forecasts. It describes the basic methodology for predicting tax revenues, both in terms of the macroeconomic approach and from a microeconomic perspective. The microeconomic approach used microsimulation methods with methods based on...
