Using a new non-parametric symmetry test we examine Canadian contract and survey data for evidence of nominal wage rigidities. We compare results from the two data sets with the view to examining the accuracy of survey data and consider whether the private/public and union/non-union sector...

We estimate a semiparametric dynamic panel data model by the local linear kernel method and we interpret the slope of the nonparametric component function as a varying slope coefficient. Thus, the slope coefficient is a smooth, but otherwise unknown, function of some of the regressors. A Monte...
