The aim of this seminar from the Essex Centre of Macro and Financial Econometrics is to explore the question does modelling a structural break improve forecast accuracy presented by Andreas Pick.

Seminar abstract

Mean square forecast error loss implies a bias-variance trade off that suggests that structural breaks of small magnitude should be ignored.

In this presentation, we provide a test ti determine whether modelling a break improves forecast accuracy.

The test is near optimal even when the date of a local-to-zero break is not consistently estimable.

The results extend to forecast combinations that weight the post-break sample and the full sample forecasts by our test statistic. In a large number of macroeconomic time series, we find that structural breaks that are relevant for forecasting occur much less frequently than existing test indicate.


This is a free event. Please feel free to join us and bring along your colleagues, classmates and friends.
