Abstract
An Euler equation model of firm investment behaviour is estimated applying an outlier robust extension of the GMM panel data estimator. Using a panel of German non-financial stock companies, the estimation results from the usual GMM estimator would contradict the economic theory, whereas the empirical results from the outlier robust GMM estimator support it. Allowing for an unknown fraction of outliers in a given time period, we find that the Euler equation model with convex adjustment costs and imperfectly competitive product markets is able to explain the investment behaviour of the bulk of the firms. Adjustment Costs are relatively moderate and investment does respond to changes in fundamentals affecting firm profits.
