An analysis of the effect of software intellectual property rights on the performance of software firms in South Korea

This paper explores the effect of software intellectual property rights (IPRs) on the performance of software firms in South Korea using the statistics of software copyright registrations and patent applications along with the financial statements of firms. According to our empirical results, R&D and software R&D input has a strong positive effect on the production of software copyrights and patents, and large firms exploit software IPRs better than small firms. We also found that there are quite different trends in the selection of the legal means of protection; firms in the software industry prefer to copyrighting, whereas firms in the manufacturing industry prefer to patenting. In addition, software copyrighting has a positive effect on software revenue and total revenue of firms, but software patenting fails to show a positive effect on software revenue. Consequently, in contrast to the prevailing consensus indicating a high preference for patenting, it is obvious in our analysis that software copyrighting is more beneficial for software firms.

Post-merger performance in the software industry: The impact of characteristics of the software product portfolio

This article studies the impact of the characteristics of software product portfolios on the performance of firms involved in a merger of software companies. The short-term financial results reveal that markets generally seem to neglect the characteristics of software product portfolios when the merger is announced. Nevertheless, such portfolios appear to have a positive impact on the price/book value ratio of merged software firms. The empirical evidence presented in this paper suggests that, in the long term, the performance of business combinations in the software industry is related to certain factors that are attributable to virtual network effects.

Modeling the unethical intention of software piracy: a qualitative integration of network externalities and information cascades

Information cascades and network externalities have been increasingly influential in explaining the many market outcomes of information technology (IT), but their application to ethical issues of IT has been limited. This study proposes a conceptual model of unethical intention of software piracy by integrating information cascades and network externalities in terms of a theoretical perspective from the literature of economics. In the conceptual model, unethical intention of software piracy is proposed to be influenced by the network benefits of using pirated software, while the network benefits are proposed to be affected by the overall adopter base of pirated software directly and indirectly through the availability of pirated complementary software. Accordingly, whereas the perception of others’ piracy is proposed to be influenced by the overall adopter base of pirated software, the unethical intention of software piracy is proposed to be influenced indirectly by the perception of others’ piracy through the perceived signal that piracy seems a good idea. Finally, this study also provides the conclusion and limitation.     

The equivalence of supporting software delegation and sales delegation

This paper considers a duopoly market with horizontally differentiated system goods to examine system owners' behaviors under supporting software delegation, in which owners of system firms use varieties of supporting software, coupled with profit, to evaluate their managers' performance. Supporting software delegation seems to induce managers to act more aggressively in price competition than sales delegation does; however, we prove that if two systems are compatible and the varieties of supporting software are determined by hardware owners' overall expenditure amount on software, then supporting software delegation is equivalent to sales delegation. Owners of system firms induce their managers to act less aggressively in hardware price competition by offering contracts with a negative weight on varieties of supporting software under supporting software delegation. We find that stronger network externalities do not reverse system owners' contracting behaviors under supporting software delegation. Finally, it is worth mentioning that hardware technologies are static in this paper. In other words, dynamic changes such as hardware evolution are not considered in our analysis.
