Those of you following the literature on the economic effects of R&D may have seen a paper by Van Elk et al. on the economic effects of investment in public R&D. Those who really follow that literature well may have seen both the working paper version, and the officially published one, and have noticed a slight change in authorship between those two versions. More specifically, I was an author (named Al) in the working paper version, but in the journal version, I was just a line in a footnote. Let me explain here how that came about.

The Dutch Ministry of Economic Affairs and Climate just published our evaluation report on the R&D tax credit policy WBSO, for the period 2011-2017. The evaluation was done in a collaboration between Dialogic, APE and UNU-MERIT.

One important topic in my work is the analysis of patent citation networks. These networks are kind of special, because they are a-cyclical and directed (contrary to most other networks that economists analyze, which often contain cycles and are non-directed). This work started with a publication in Advances in Complex Systems, dealing with fuel cells. If you don't have access to this journal, you may download the paper here.

The topic of growth rate differentials between countries has been a main theme in my work from the very beginning. It was the main topic of my PhD thesis of 1992. Chapter 6 of that thesis contains my model of catching up and falling behind (see picture below), which was also published in 1991 in the Elsevier Journal Structural Change and Economic Dynamics. if you do not have access to that journal, you can download the paper here.
