The Norwegian productivity puzzle is rooted in three seemingly contradictory “facts”: First, Norway is one of the most productive OECD countries. Second, Norway has experienced high growth in productivity. Third, Norway has a relatively low level of R&D intensity. In this article, I show...

The empirical literature studying the sector bias of technical change has only focused on skill-biased technical change. In this paper, I analyse the sector bias of both factor-neutral and factor-biased technical change. In Norwegian data from 1972 to 2007 the empirical evidence is not clear on...

We bridge mathematical number theory with that of optimal control and show that a generalised Fibonacci sequence enters the control function of finite horizon dynamic optimisation problems with one state and one control variable. In particular, we show that the recursive expression describing...

The standard cost-of-living index hinges on the assumption that there is free trade. Applying it to situations where trade barriers are present yields biased results with respect to a true cost-of-living index. Import price indices are particularly vulnerable to this bias since many of the goods...
