''A bootstrap test of the time-varying efficiency of German growth forecasts'' |

I use a bootstrap approach to re-examine the time-varying efficiency of growth forecasts for Germany. I argue that, given this small sample of forecasts, the bootstrap approach renders it possible to trace out with more precision than a standard full-sample forecast-efficiency-regression model whether forecasts were efficient at any given point in time. As an empirical application of the bootstrap approach, I present results for six-months-ahead and one-year-ahead growth forecasts published by three German economic research institutes during the sample period 1970$-$2018. The results illustrate that the bootstrap approach, for various configurations of the forecast-efficiency-regression model, yields stronger evidence against forecast efficiency than a conventional full-sample model. |
