This paper presents a new graphical analysis of how a profit-maximizing firm will respond when required to control pollution. The focus is on graphical presentations which attempt to integrate the two pollution reduction responses open to the firm: output reduction and use of abatement...

This paper addresses the link between the degree of unreliability of bus services and the level of optimal bus subsidy. With unreliability influencing user cost, and user cost being a key determinant of optimal bus subsidy, it follows that there is a link between service unreliability and...

We show that optimal public transport subsidy is sensitive to the use of alternative user cost models, and that a model based on cost minimisation principles may lead to an improvement in subsidy estimates. For the case of homogeneous consumers and non-peaked demand, the cost minimisation user...

Conventional analysis of pollution control policy under uncertainty does not properly account for the potential cost effectiveness difference between standards and charges, thus drawing misleading conclusions for the case of inefficient standards. Correcting for this anomaly, the following...
