Both unconditional mixed-normal distributions and GARCH models with fat-tailed conditional distributions have been employed for modeling financial return data. We consider a mixed-normal distribution coupled with a GARCH-type structure which allows for conditional variance in each of the...

Financial shocks represent a major driver of fluctuations in tail risk, defined as the 5th percentile of the forecast distributions of output and inflation. Since the variance and the asymmetry of the forecast distributions are largely driven by the left tail, financial shocks turn out to play a...

We develop a parsimonious New Keynesian macro-finance model with downward nominal rigidities to understand secular and cyclical movements in Treasury bond premia. Downward nominal rigidities create state-dependence in output and inflation dynamics: a higher level of inflation makes prices more...

There are several possibilities to introduce skewness into a symmetric distribution. One of these procedures applies … density. Within this work we show that this technique incorporates a well-defined parameter of skewness, i.e. that the … generated distributions are skewed to the right (left) if the parameter of skewness takes values less (greater) than one …

Generalized autoregressive conditional heteroskedasticity (GARCH) processes have become very popular as models for financial return data because they are able to capture volatility clustering as well as leptokurtic unconditional distributions which result from the assumption of conditionally...
