Abstract: We use a stylized gas system to study the use of access-to-gas storage in a seasonal model. In a duopoly setting, we find that welfare is higher under vertical integration and open access organization than under separate management of storage and distribution. This raises questions about recent regulatory reforms in the gas sectors in the US and Europe, supporting the separation of storage and merchant activities. In the absence of other justifying reasons such as encouraging competition by creating a level playing field, separating the management and accounting functions of storage activities from those of distribution may be a better option than real divestiture, on the basis of welfare arguments.

Environmental Valuation & Cost Benefit News covers legal, academic, and regulatory developments pertaining to the valuation of environmental amenities and disamenities, such as clean air, trees, parks, congestion, and noise. We apprise the reader about ways in which costs and benefits are measured, and the results of empirical studies. We hope that this information will allow public and private organizations to comprehend the risks and benefits of various actions, help disputants to resolve conflicts equitably and efficiently, and improve the quality of public policies. We will only discuss issues related to the empirical quantification of private and social costs and benefits and damages, and summarize information from daily newspapers, academic journals, legal publications, court decisions, professional newsletters commissioned studies, and on-line services. This newsletter is dedicated to the principal that all policies place values upon life, liberty, and the pursuit of happiness. We believe that more information, explicit specification of assumptions, and rigorous analysis can help our society to better meet these ends. This site will increasingly serve, in conjunction with others, as a valuation database. We will include a wide range of studies, including non-environmental reports, because omission of a factor effectively values it at zero, and biases decisions. Heavy traffic has caused several site crashes. We are attempting to correct these problems. Apologies for any inconvenience.
