After presenting the history, the evolution and the content of innovation surveys, we discuss the characteristics of the data they contain and the challenge they pose to the analyst and the econometrician. We document the two uses that have been made of these data: the construction of...

Previous studies on the determinants of the choice of college major have assumed a constant probability of success across majors or a constant earnings stream across majors. Our model disregards these two restrictive assumptions in computing an expected earnings variable to explain the...

From cross-sectional data of 460 firms that responded to both the 1988 and the 1992 Dutch innovation surveys we have reexamined the causality direction between R&D and patents, using data on contemporaneous and four-year lagged patent applications and R&D expenditures. The two equations have...

This paper proposes a framework to account for innovation similar to the usual accounting framework in production analysis and a measure of innovativity comparable to that of total factor productivity. This innovation accounting framework is illustrated using micro-aggregated firm data from the...

In this paper we consider models of this class and examine their potential when it comes … models, and we provide a feasible way to price options in this framework.
