In this paper we examine how the timing of investment affects the levels of quality chosen by firms. We show that in a model with vertical quality differentiation a game with sequential quality choice induces both firms to make smaller quality investments than they would in a game with...

This paper examines the consequences of the differences in the timing of information disclosure between the U.S. and Japanese patent systems. Under the Japanese system it is possible for a firm to apply for a patent knowing the exact specifications of a rival's patent application. In contrast,...

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...
