This paper explores the usefulness of bagging methods in forecasting economic time series from linear multiple regression models. We focus on the widely studied question of whether the inclusion of indicators of real economic activity lowers the prediction mean-squared error of forecast models...

A common problem in out-of-sample prediction is that there are potentially many relevant predictors that individually have only weak explanatory power. We propose bootstrap aggregation of pre-test predictors (or bagging for short) as a means of constructing forecasts from multiple regression...

A natural conjecture is that impulse … hence potentially more reliable in small samples than VAR-based estimators. We show that - contrary to this conjecture - LP … are typically less accurate and wider on average than suitably constructed VAR-based intervals. Bootstrapping the LP …
