The most frequently applied test statistics for a unit root are the Dickey-Fuller tests, which are built into many econometric packages along with MacKinnon's empirical response functions. This article provides empirical response functions for some easy to compute alternative test statistics...

This article compares the behaviour of sampling techniques for price indices using a scanner data set as a model population. Indices produced by two purposive deterministic cut-off designs and four probabilistic sampling schemes are compared with each other and with the 'true' population index...

There is an emerging literature in the field of hedonic regressions which successfully applies flexible functional forms. In contrast, numerous authors report hedonic regressions with relatively simple functions, often with little or no attempt to consider interaction terms and higher level...

Scanner data are used to calculate chained, exact (and superlative) hedonic price indexes for television sets. The data source is available for a wide range of goods, the application providing an example of how this method can be more widely applied. The indexes correspond to constant utility,...
