Performance and behavioural properties of markets in patents are studied using a contract with a two-part tariff (fixed fee and royalty) on patented technology with limited validity and random values, in an economic experiment. Performance doubles when demand side bidding is introduced for both tariffs, resulting in gains from trade, compared with supply side take-it-or-leave-it offers. This departs from the hierarchical view of (Arrow, 1962), where the invention and innovation takes place in the same firm, eliminating any gains from trade in the analysis. An informal theory is proposed, based on insurance of market access, and tested. The sustained prices support the hypothesis that fixed fee = blocking value, thus supports rational expectations according to Muth under conditions of demand-side bidding in both tariffs. Understanding nature then drives demand for science (North, 1981). What made productivity grow in Europe may therefore have been the patent system by increasing growth in economically useful technology through a producer market.

Ratio Working Paper No. 351: Knowledge Spillovers in the Solar energy sector
Working paperPublikation
Grafström, J.


Publicerat i



The purpose of this paper is to provide an analysis of the existence and possible direction of international knowledge spillovers in the solar energy sector. Specifically, the paper investigates how the accumulation of solar energy patents and public R&D spending affected the output of domestic granted solar energy patents. The econometric analysis relies on a data set consisting of most of the OECD countries plus China and analyzes two time periods; from 1990 to 2014 and the years 2000 to 2014. To analyze the data material, a Poisson fixed-effects estimator based on the Hausman, Hall and Griliches (1984) method was used. The empirical findings suggest that the domestic accumulation of patents and R&D is important for the potential development of new ones. Indeed, early investment in specific technology can be an indicator of future leadership in that field.

Digitally intermediated peer-to-peer exchanges have accelerated in occurrence, and as a consequence, they have introduced an increased pluralism of connotations. Accordingly, this paper aims to assess user perceptions of the interplay between the sharing, access, platform, and community-based economies.

The sharing, access, platform, and community-based economies have been systematically tracked in the social media landscape using Social Media Analytics (SMA). In doing so, a total material of 62,855 publicly posted user-generated content concerning the four respective economies were collected and analyzed.

Even though the sharing economy has been conceptually argued to be interlinked with the access, platform, and community-based economies, the empirical results of the study do not validate this interlinkage. Instead, the results regarding user perceptions in social media show that the sharing, access, platform, and community-based economies manifest as clearly separated.

This paper contributes to existing literature by offering an empirical validation, as well as an in-depth understanding, of the sharing economy’s interlinkage to other economies, along with the extent to which the overlaps between these economies manifest in social media.
