Exchange rate exposure: A nonparametric approach

The typical conclusion reached when researchers examine exchange rate exposure is that only a few firms are exposed. This finding is puzzling since institutional knowledge and theory suggests a larger effect. In this paper, we compare results obtained using a linear approach with those from nonlinear and nonparametric models. Among firms that don't have a linear exposure, we find that a considerable proportion of these are exposed when nonlinear or nonparametric models are used. This exposure is most striking when a nonparametric model is used. We also find that firms' hedging activities decrease linear exposure but don't affect nonparametric exposure.
