We develop a framework to examine how a standard evolves when a standard consortium or firm (incumbent) innovates either to improve the standard or to strengthen the installed base, which increases switching costs. Both investments make it more difficult for another firm (entrant) to introduce a...

We present a framework to examine how a standard evolves when a standard consortium or a firm (incumbent) innovates either to improve the standard or to strengthen installed base which increases switching cost. Both investments make it more difficult for another firm (entrant) to introduce a...

In this paper, we propose nonlinear elliptical models for correlated data with heteroscedastic and/or autoregressive structures. Our aim is to extend the models proposed by Russo <italic>et al.</italic> 22 by considering a more sophisticated scale structure to deal with variations in data dispersion and/or a...

The issue of assessing variance components is essential in deciding on the inclusion of random effects in the context of mixed models. In this work we discuss this problem by supposing nonlinear elliptical models for correlated data by using the score-type test proposed in Silvapulle and...

We consider patent pool formation by owners of essential patents for differentiated standards that may be complements or substitutes in use. Pooling improves coordination in terms of royalty setting within a standard but provokes a strategic response from licensors in the competing standard. We...

We present results from a survey conducted in December 2011, in order to see if introduction of Demeny voting system will have the desired have effect of addressing gerentocracy. We have identified several facts from the survey that provides a positive answer to this question. We found that...

We look at cumulative innovations and the protection of basic research which does not carry stand-alone commercial values in an international setting. Due to the complementarity of the innovations, we ・d that for some parameter range, technology leading countries do not always prefer the...

With uncertain scope of patent protection and imperfect enforcement, the effective strength of patent protection is determined by the legal system. We analyze how the legal system affects the incentives of firms to innovate, taking into account possibilities of strategic licensing and litigation...
