The study shows that consumers are willing to pay a significant premium for spreadsheets that are compatible with the Lotus platform and for spreadsheets that offer(More)
Open source software (OSS) is an economic paradox. Development of open source software is often done by unpaid volunteers and the " source code " is typically freely available.

In particular, we model three decisions of the firm: (I) an upfront investment in the quality of the software to reduce potential vulnerabilities, (II) a policy decision whether to announce vulnerabilities, (III) and a price for the(More)
Knowledge spillovers are a central part of knowledge accumulation. The paper focuses on spillovers that occur through the interaction between different researchers or developers that collaborate in different research projects. The paper distinguishes between project spillovers and contributors' spillovers and between direct and indirect spillovers. The(More)
