This paper studies the role of geographic proximity for interaction on R&D, by exploring the special case of university-industry contacts. While numerous studies find that geographic proximity facilitates spillover effects between university and industry by utilising evidence from e.g. patenting and publishing activities, the geographical dimension is largely understudied in studies that report...

We study platform owner’s decision to enter the market complementary to its platform with its own rival complement, and the consequences of such an entry on complementors’ innovation behavior. We ask: if a platform owner like Google releases an app for its Android platform, does it keep app developers from innovating in the future? We investigate two mechanisms that suggest entry to stimulate c...

This study distinguishes multinational firm (MNE) technology-spillover from learning effects. Whenever learning takes time, the model predicts that foreign investors deduct the economic value of learning from wages of inexperienced workers and add it to experienced ones to prevent them from moving to local competitors. Hence, the national wage bill is unaffected by the presence of MNEs. In cont...

This article analyzes direct and indirect effects of foreign ownership on productivity in the Turkish manufacturing plants between 1990 and 1996. First, based on Olley-Pakes production function estimates, foreign affiliates are shown to be more productive than local plants. Using sectoral output shares of foreign affiliates and 1990 input-output matrix to identify linkages across plants, regres...

This paper surveys some recent work which seeks to model persistent income inequality and explain such phenomena as ghetto formation and poverty traps. The paper illustrates how a number of these models possess a common structure in which local spillover effects interact with income-based stratification of neighborhoods to transmit parental economic status from generation to generation. As such...

This paper reports on how a university Introductory Psychology course was restructured after a campuswide information technology program was introduced at a small Canadian university. Our use of the campus Intranet and the Internet resulted in a technologyenhanced lecture environment, greater student exchange of ideas, greater and more efficient communication between the instructor and students...

This paper presents an analysis of a multi-agent system intended to model total task completion rates in collaborating communities. The spillover effect is emergent. We begin to quantify externality of marginal utilities. We are concerned with maximizing the output of the given community through regulation of agent to task ratios. We outline emergent externalities when collaboration occurs, eve...

There is a growing literature on implied volatility indices in developed markets. However, no similar research has been conducted in the context of emerging markets. In this paper, an implied volatility index (GVIX) is constructed for the fast developing Greek derivatives market. Next, the properties of GVIX are explored. In line with earlier results, GVIX can be interpreted as a gauge of the i...

We conducted a field experiment with the American Red Cross to study the effects of economic incentives on volunteer activities. The experiment was designed to assess local and short-term effects, but also spatial and temporal substitution, heterogeneity and spillovers. Subjects offered $5, $10, and $15 gift cards to give blood were more likely to donate, and more so for the higher reward value...

This paper examines R&D tax incentives in oligopolistic markets. It is generally agreed that R&D has some characteristics of a public good. Therefore, the market will fail to provide a sufficient amount of R&D. A tax incentive for R&D can be implemented by the government to fix this market failure. However, the controversy over the effectiveness of R&D tax incentives is still considerable. In t...
