Environmental policies in a differentiated oligopoly revisited

Constructing a model of polluting oligopoly with product differentiation, we consider how product differentiation, together with the presence and absence of free entry, affects optimal pollution tax/subsidy policies. The sign of the short- and long-run optimal pollution taxes are highly sensitive to the parameter measuring product differentiation as well as the presence of free entry. How they are affected by a change in product differentiation, which is not addressed in the existing literature, is also made clear.     

Models of regional growth: An empirical evaluation

Cross section data are used to test two types of regional growth models: the demand and the supply based models. While the demand based model explained twice as much of the interregional variations in growth rates as did the supply model, we found that the basic element of the supply model, factor mobility, contributes significantly to the determination of regional growth. A model combining both demand and supply is developed and fitted tothe data. The performance of this model as judged by goodness of fit and dynamic simulations is remarkable. Long-run implications are derived from dynamic simulations.     

Real options analysis on strategic partnerships of biotechnological start-ups

Since there is a mismatch between long-term basic research and short-term financial markets, the dependency of biotechnology (biotech) start-ups on strategic partnerships with pharmaceutical companies is expanding more than on venture capital. The research objectives are to examine the difference between license-fee elements, try to determine the innovation valuation in strategic partnerships, and minimise the risk in partnership formation for both sides. A key concept is that a biotech start-up is defined as a portfolio of real options based on an entrepreneur's ideas about investment opportunity. Methodologies used are compound options and stochastic optimisation for innovative but risky projects. In conclusion, this paper tries to address a wider scope with a deeper theoretical grounding, by using the real options perspective for the valuation of innovation partnership, through a biotech license-fee case study for simulation. Furthermore, the real option valuation can be expected to improve open innovation from matchmaking to innovation partnership.
