New technology and restructuring in the UK energy industry: the case of renewable energy

Among the justijcations for the UK government's electricity privatization programme was the suggestion that it would stimulate the development of a range of new supply options, including the UK's extensive renewable energy resource. This paper assesses the prospects for renewable energy technologies i n the UK after privatization. It finds that there is enthusiasm for renewables, but that the market alone will not stimulate renewables effectively or develop them appropriately, and that state support and regulation will be necessary.     

The political economics of investment Utopia: public–private partnerships for urban infrastructure finance

This article explores the policy disconnect between the pursuit of private investment return and the public desire for enhanced social value from public–private partnership (P3) investments in urban infrastructure. Investors view infrastructure finance as an opportunity for relatively safe, high-return investing. But infrastructure-financing architecture to achieve high private returns frequently clashes with financing models that sustain long-term social benefits. The full implications of relational tensions in the structuring of P3s are analyzed. The principal policy conclusion is that, because of these tensions, the use of P3s for this purpose should be restricted.     

Incorporating choice dynamics in models of consumer behavior

This paper presents a framework for organizing and discussing factors influencing consumer choice dynamics, how these factors may be incorporated into models of buyer behavior and problems that may arise in estimating such models. The paper identifies research issues and delineates possible approaches. Proceedings of Session on Choice Dynamics at the Banff Symposium on Consumer Decision-Making and Choice Behavior.

Variability in overseas travel by Americans, 1820–2000

There were substantial fluctuations in the number of American overseas travelers, especially before World War Two. These fluctuations in travel around the long-term upward trend are the focus of this paper. We first identify those fluctuations in the data and then try to explain the patterns. We show that, despite the impact of a myriad of episodic events, fluctuations in travel can be explained to a large extent by changes in the direct price of travel, changes in per capita GDP and wealth in the United States, and by periods of armed conflict.     

Numerical evaluation of the critical price and American options

An approximate solution to the American put value is proposed and implemented numerically. Relaxation techniques enable the critical price to be determined with high accuracy. The method uses a modification of the quadratic approximation of MacMillan and Barone-Adesi and Whaley which gives an expression for the critical price. Numerical experimentation and iterative methods quickly provide highly accurate solutions.
