The focus of this paper is on the microeconometric analysis of spatial choice in a cross section. Nested multinomial logit models are used to analyze the determi-nants of individual choice among destinations and vacation activities. Cramer and Ridder's likelihood ratio test for pooled...

This paper estimates trade-demand functions for Germany from monthly data covering the period 1959-1988. It is assumed that these trade-demand functions have the form of the Linear Expenditure System, generated by a shifted Cobb-Douglas trade-utility function in which the shift parameter is...

Der Vortrag beschreibt die Entwicklungen der letzten zehn Jahre bezüglich des Zugangs zu amtlichen Mikrodaten, insbesondere Unternehmens- und Betriebsdaten. Dabei werde ich vor allem auf Ergebnisse aus drei Projekten eingehen, an denen ich selbst mitgewirkt habe: (a) Anonymisierung von...

Use of microdata is severely hampered in many areas of research. This is in particular true for data from statistical offices. One way to circumvent this problem is to anonymize the data such that both confidentiality is guaranteed and informational content of the data is not too much distorted...

Empirical research using micro data via remote access has been advocated in recent time by statistical offices since confidentiality is easier warranted for this approach. However, disclosure of single values and units cannot be completely avoided. Binary regressors (dummy vari- ables) bear a...

Remote access as well as remote analysis solve many problems arising from granting researchers access to sensitive data. Both allow to run analyses without actually seeing the data. Therefore none of them demand either substantively altering the data or strictly restricting the access to it....
