Changing product quality poses a challenge for the computation of price indexes, in particular in technologically advanced industries. We assess the differences between traditional and quality-corrected indexes by computing hedonic and matched-model price indexes for personal computer database...

In diesem Beitrag wird ein Oligopolmodell der Innovationsaktivität entwickelt und mit Daten aus dem Mannheimer Innovationspanel geschätzt. Das Modell erlaubt es, bei der empirischen Umsetzung auf die Verwendung von Marktanteilsdaten und Nachfrageelastizitäten zu verzichten, die typischerweise...

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....

We explore the tail of patented invention value distributions by using value estimates obtained directly from patent holders. The paper focuses on those full-term German patents of the application year 1977 which were held by West German and U.S. residents. The most valuable patents in our data...

We evaluate the impact of a major European state aid program for broadband deployment applied to rural areas in the German State of Bavaria in the years 2010 and 2011. Using difference-in-differences estimation strategies, we find that aided municipalities have – depending on broadband quality...

Patent renewal studies reveal a highly rightward-skewed distribution of patent values. Our approach elicits valuations approximating those of the patented invention. This paper focuses on the full-term patents of the application year 1977 held by West German and U.S. residents. The tail of...

We exploit Germany’s reunification to identify how school-age education affects entrepreneurial intentions. We look at university students in reunified Germany who were born before the Iron Curtain fell. During school age, all students in the West German control group received formal and...
