The paper suggests two encompassing tests for evaluating multi-step system forecasts invariant to linear transformations. An invariant measure for forecast accuracy is necessary as the conclusions otherwise can depend on how the forecasts are reported (e.g., as in level or growth rates)....

We investigate the question of whether macroeconomic variables contain information about future stock volatility beyond that contained in past volatility. We show that forecasts of GDP growth from the Federal Reserve's Survey of Professional Forecasters predict volatility in a cross-section of...

The economic upswing in Germany continues, although the expansion loses some steam. Compared to our summer forecast, we reduced our expectations for GDP growth by 0.1 and 0.3 percentage points in the current and next year, respectively, to 1.9 percent (2018) and 2.0 percent (2019). So for now,...

We develop a vector autoregressive model with time variation in the mean and the variance. The unobserved time-varying mean is assumed to follow a random walk and we also link it to long-term Consensus forecasts, similar in spirit to so called democratic priors. The changes in variance are...

Es liegt in der Verantwortung von ökonomischen Entscheidungsträgern, Entscheidungen unter Unsicherheit zu treffen. Finanzmarktunsicherheit kann ökonomische Aktivität negativ beeinflussen. In diesem Sinn können Prognosen theoretisch einen ökonomischen Mehrwert liefern. Diese kumulative...

I regress real GDP growth rates on the IMF's growth forecasts and find that IMF forecasts behave similarly to those generated by overfitted models, placing too much weight on observable predictors and underestimating the forces of mean reversion. I identify several such variables that explain...
