The literature on vertical integration in markets with regulated upstream prices suggests that the integrated upstream firm might engage in non-price discrimination. Several studies provide policy recommendations derived either from case study approaches or based on theoretical modeling which...

Contractual and regulatory provisions for access affect incentives to invest in an upgraded network and, in particular, a next-generation access network. Investment decisions are made under uncertainty and have to be made over time. This papers provides a framework for taking uncertainty, risk...

We analyze a dynamic multi-pollutant problem where abatement costs of several pollutants are not separable. The pollutants can be either technological substitutes or complements. Environmental damage is induced by the stock of accumulated pollution. We find that optimal emission paths are...

The traditional argument that shorter product cycles favor trade secret over patenting is reviewed. A game theoretic model provides an argument that shorter product cycles can induce firms to file more patent applications. The firms may be trapped in a prisoners' dilemma where all firms would...

Much of the empirical literature analysing the relation between environmental innovation and competitiveness has focused on the question whether 'it pays to be green'. We differentiate between different types of environmental innovations, which will be disentangled in those aiming at reducing...

This paper examines the linking of price-based and quantity-based provision of a public good by two parties in the example of pollution control under a global quantity constraint, using a stochastic partial-equilibrium model. One country chooses a price-based instrument (tax) and trades with...

Without participation of the United States, the world?s largest emitter of greenhouse gases, mitigation of global climate change seems hardly conceivable. Despite the U.S. rejection of the Kyoto Protocol and the reluctance of the Bush administration to engage in Post-Kyoto negotiations, recent...
