In der Arbeit wird Fuzzy-Regression als mögliche ökonometrische Analysemethode bei fehlerbehafteten Daten modelliert und erprobt. Dazu ist die interpretatorische Lücke zu schließen, die einerseits zwischen den Datenproblemen in empirischen Datensätzen und ihrer Modellierung als Fuzzy-Daten...

We propose a new specification test for assessing the validity of fuzzy regression discontinuity designs (FRD-validity). We derive a new set of testable implications, characterized by a set of inequality restrictions on the joint distribution of observed outcomes and treatment status at the...

A new bandwidth selection method for the fuzzy regression discontinuity estimator is proposed. The method chooses two bandwidths simultaneously, one for each side of the cut-off point by using a criterion based on the estimated asymptotic mean square error taking into account a second-order bias...
