| Abstract: | In this study, a theoretical model is developed in which the sophistication of technologies improves over time due to research and development (R&D) undertaken by software developers in two sectors. In the commercial sector (here as: cmm-s.), R&D intensity (as: int-y.) is driven by economic incentives, whereas in the sector using the General Public License (GPL), R&D int-y. is driven by the preference-based labour supply of individuals. A higher amount of GPL labour allocation generates equilibrium effects affecting adversely commercial software development. When the degree of imitation in the GPL sector is relatively higher than in the cmm-s., ... the R&D int-y. in the cmm-s. would decline by more than any increases in R&D int-y. in the GPL sector. Hence, in the long run the aggregate R&D int-y. would be reduced. Based on numerical simulation, this outcome is indicated to pertain under realistic parameter ranges. |
