In the article we examine what determines the Polish sovereign Credit Default Swap dynamics. We consider not only measures of changes of the economic situation of the country, but also the impact of the international data. We find that the dynamics of the Polish sCDSs is very vulnerable to the...

We develop an econometric modelling framework to forecast commodity prices taking into account potentially different dynamics and linkages existing at different states of the world and using different performance measures to validate the predictions. We assess the extent to which the quality of...

There is now an impetus to apply dynamic stochastic general equilibrium models to forecasting. But thesemodels typically rely on purpose-built data, for example on tradable and nontradable sector outputs.How then do we know that the model will forecast well, in advance? We develop an early...

Generalized autoregressive conditional heteroscedasticity in-mean model allows accounting for both time-varying variance and risk premium in financial time series data. This paper introduces an extension of this particular model with more flexible parameterization of the way variance enters the...

This paper contains a brief survey of nonlinear models of autoregressive conditional heteroskedasticity. The models in question are parametric nonlinear extensions of the original model by Engle (1982). After presenting the individual models, linearity testing and parameter estimation are...

This paper contains a survey of univariate models of conditional heteroskedasticity. The classical ARCH model is mentioned, and various extensions of the standard GARCH model are highlighted. This includes the Exponential GARCH model. Stochastic volatility models remain outside this review.

This paper models the univariate dynamics of seasonally unadjusted quarterly macroeconomic time series for the Indian economy including industrial production, money supply (broad and narrow measures) and consumer price index. The seasonal integration-cointegration and the periodic models are...
