We study competitive interaction between profit-maximizing firms thatsell software and complementary goods or services. In addition totactical price competition, we allow firms to compete through businessmodel reconfigurations. We consider three business models: theproprietary model (where all...

Empirical research on Free/Libre/Open Source Software (FLOSS) has shown that developers tend to cluster around two main roles: "core" contributors differ from "peripheral" developers in terms of a larger number of responsibilities and a higher productivity pattern. A further, cross-cutting...

In this paper we will discuss the organization of work which is found to be present in open source projects, and the implications for the expended effort as well as achieved efficiency. The paper is based on several empirical analyses of open source communities. The main method employed is...

W artykule podjęto próbę określenia, jakimi powodami kierują się użytkownicy podczas wyboru oprogramowania Open Source. Wykorzystano analizę korespondencji, aby zbadać zależność pomiędzy używaniem programów z wybranych grup oprogramowania a deklarowanymi powodami ich wykorzystania...

PySAL is an open source library for spatial analysis written in the object-oriented language Python. It is built upon shared functionality in two exploratory spatial data analysis packages--GeoDA and STARS--and is intended to leverage the shared development of these components. This paper...

Increasing development of information and communications technology, continuously transform how the world transmit, receive and manage information. Knowledge transfer switch from classic source - passive receiver to a more complex model, where each receiver can become a new source that...

El presente artículo es un breve repaso del estado de la cuestión en torno a los recursos disponibles para los creadores contemporáneos. Una reflexión sobre la propiedad intelectual, sus orígenes y alternativas existentes. Con el objetivo de ser lo más claros posible, lo hemos estructurado...

The rivalry between developers of open source and proprietary software encourages open source developers to court users and respond to their needs. If the open source developer wants to promote her own open source standard and solutions, she may choose liberal license terms such as those of the...

In this paper I study how innovation investment in a software duopoly is affected by the fact that one of the firms is, or might become Open Source. Firms can either be proprietary source (PS) or open source (OS), and have different initial technological levels. An OS firm is a for profit...

We present a model of industry equilibrium to study the coexistence of Open Source (OS) and Proprietary (P) firms. Two novel aspects of the model are: (1) participation in OS arises as the optimal decision of profit-maximizing firms, and (2) OS and P firms may (or may not) coexist in...
