We examine the impact of an optimal emissions tax on research and development of emission reducing green technology (E-R&D) in the presence of R&D spillovers. We show that the size and eectiveness of the optimal emissions tax depends on the type of the R&D spillover: input or output spillover....

This paper performs a comparison of two well known approaches for modelling R&D spillovers associated with investment in green technology, namely D?Aspremont-Jacquemin and Kamien-Muller-Zang. We show that there is little qualitative difference between the models in terms of total surplus...

Using a data set spanning the period 1899-2000, we construct a network of RJVs and track the pattern of growth of this network over time. The resulting R&D network is emergent in the sense that RJVs are contained within it, connected to other RJVs by the existence firms sharing membership with...

This paper builds an econometric model of retail gas competition to explain the pricing decisions of retail outlets in terms of vertical management structures, input costs and the characteristics of the local market they operate within. The model is estimated using price data from retail outlets...

The worldwide scare over the 'Y2K bug result in the expenditure of hundreds of billions of dollars on Y2K compliance and conversion policies. Most of this can be seen, in retrospect, to have been unproductive or, at least, misdirected. In this paper, the technological and institutional factors...

The rise of New Media associated with the Internet has radically changed many aspects of daily life, and enabled us to do things that would have seemed unimaginable even a few decades ago. The speed and volume of communications has increased by a factor of a million or more since the Internet...

Chambers and Quiggin, claim that the state-contingent approach provides the best way to think about all problems in the economics of un- certainty, including problems of consumer choice, the theory of the firm, and principal?agent relationships. The purpose of this paper is to restate this...
