Through a survey, economic value estimates were obtained on 962 inventions made in the United States and Germany and on which German patent renewal fees were paid to full-term expiration in 1995. A search of subsequent U.S. and German patents yielded a count of citations to those patents....

Forschungsarbeiten der frühen neunziger Jahre betonen stark das Konzept, nach dem institutionelle Unterschiede zwischen einzelnen Ländern entscheidend für den technischen Wandel sind. In der Europäischen Union erfolgte im letzten Jahrzehnt eine umfassende Handelsliberalisierung; es wurde...

In this paper we specify and estimate a structural model which links product market competition and union power. The model has a two-stage setting in which wages are determined through bargaining between management and unions in the first stage, with a price-setting market game to follow in the...

This paper takes an innovative approach to test the relationship between technical efficiency and the market structure hypothesis which states that competitive pressure enhances relative efficiency. DEA and FDH time series of technical efficiency scores, for a panel of 11 US airlines observed...

Using time-series cross-section data from the manufacturing sector of the 11 Bundesländer from 1970 to 1993, we examine the impact of road infrastructure on private production applying three different approaches; i.e., a Cobb-Douglas production function, a translog production function and a...

Diese Arbeit quantifiziert Verzerrungen, die sich bei der Verwendung von Daten aus der IAB-Beschäftigtenstatistik in Analysen von Betriebsgründungen und -schließungen ergeben können. Wir zeigen, daß bisherige Studien von Gründungs- und Schließungsdaten ausgegangen sind, die im Mittel...
