Software Development Project Pricing:

Over the past three decades, there has been considerable amount of research done in the area of pricing and the role price plays as a determinant of a purchase decision. Although price is only one aspect that stimulates a purchase decision, it is probably the most important. With the history of pricing filled with failures, ongoing efforts are being made to enhance the processes and techniques used in pricing. The nature of software development projects, taking on the characteristics of a service, and the inherent inaccuracies of software cost estimation methods, adds further considerations on what pricing objectives should be used, how pricing strategies should be formulated, and which pricing method should be adopted. The complexities of pricing are further aggravated by the technical and business context of software development projects. Decision makers and marketers also have to price competitively and yet profitable for software development contracts which are mostly awarded through bidding. Current pricing practices are reviewed, and a pricing framework is presented to aid practitioners and academicians in the pricing of software development projects.

Idiosyncrasies of the Software Development Process and Their Relation to Software Patents: Theoretical Considerations and Empirical Evidence

In Europe, the future patenting of software-related inventions has been the subject of intensive discussions for some time, since there exists a strong dispute between the supporters of the U.S. practice of allowing patents in order to increase Europe's competitiveness and the opponents postulating negative impacts of patents on the software development process. This paper presents empirical results about the idiosyncrasies of the software development process and tests hypotheses on their impact on the likelihood of patents being obstacles for software dvelopment. The paper concludes with the identification of determinants for preferences concerning different possible patent regimes in the future.

Fighting Software Piracy: Some Global Conditional Policy Instruments

This study examines the efficiency of tools for fighting software piracy in the conditional distributions of software piracy. Our paper examines software piracy in 99 countries over the period 1994–2010, using contemporary and non-contemporary quantile regressions. The intuition for modelling distributions contingent on existing levels of software piracy is that the effectiveness of tools against piracy may consistently decrease or increase simultaneously with the increasing levels of software piracy. Hence, blanket policies against software piracy are unlikely to succeed unless they are contingent on initial levels of software piracy and tailored differently across countries with low, medium and high levels of software piracy. Our findings indicate that GDP per capita, research and development expenditure, main intellectual property laws, multilateral treaties, bilateral treaties, World Intellectual Property Organisation treaties, money supply and respect for the rule of law have negative effects on software piracy. Equitably distributed wealth reduces software piracy, and the tendency not to indulge in software piracy because of equitably distributed wealth increases with the increasing software piracy levels. Hence, the negative degree of responsiveness of software piracy to changes in income levels is an increasing function of software piracy. Moreover, the relationships between policy instruments and software piracy display various patterns: U-shape, Kuznets-shape, S-shape and negative thresholds. A negative threshold represents negative estimates with the increasing negative magnitude throughout the conditional distributions of software piracy. We also discuss the policy implications of our study.     

The Impact of National Culture on Software Piracy

This paper examines the impact of the level of economic development, income inequality, and five cultural variables on the rate of software piracy at the country level. The study finds that software piracy is significantly correlated to GNP per capita, income inequality, and individualism. Implications for anti-piracy programs and suggestions for future research are developed.
