We develop a mixed oligopoly model with one public firm and two private firms to explore the licensing strategy considered by the innovated private firm. The major findings of our paper are that: firstly, if the patentee licenses the public firm under some plausible parametric range, the public...

Using the stochastic frontier analysis model, we estimate TFEE (total-factor energy efficiency) scores for 47 regions across Japan during the years 1996–2008. We extend the cross-sectional stochastic frontier model proposed by Zhou et al. (2012) to panel data models and add environmental...

However, their existence also has an economic effect. For instance, we find that the profit of a...</p>

The existing literature shows that a decrease in the degree of substitutability increases a monopoly’s incentive to bundle. This paper in addition takes into account competition in the second product market and then re-examines how intra-brand and inter-brand product differentiations affect...

This paper investigates the non-monotonic and non-linear effect of diversification on mutual fund performance. We apply a frontier-based efficiency measure, the stochastic frontier approach, to estimate fund efficiency and the benefit of diversification. The empirical results indicate that...
