Local Rail Services: A Case Study of a New Service between
Leicester and Burton-on-Trent". Workina Paver 260, Institute for

This paper assesses the potential for a new rail service between
Leicester and Burton-on-rent. In order to do this, three sets of
demand forecasts were produced. These were based on Revealed
Preference (RP) models that had been developed in West Yorkshire,
a Stated Intentions (SI) survey of the Leicester-Burton corridor
and Stated Preference (SP) models developed for the Ashby/
Coalville -and Outer Leicester areas. It was found that these
three approaches gave a wide range of forecasts but it was felt
that the SI survey, adjusted for the findings from the SP models,
were likely to give the most reliable estimates of usage. As a
result, it was concluded that, given patronage growth over time,
total usage of the line would amount to between 3,000 and 4,000
trips on an average day.
The demand forecasts were then used as input to an evaluation
framework which took into account capital costs, operating costs,
revenue and time savings. Even if actual usage reached the upper
level of our forecasts it was shown that, although operating
costs would be covered, only some of the capital costs would be
paid back. Consideration of user time savings strengthens the
case for the scheme but even so a return on capital would still
not be achieved. Therefore, it was concluded that the case for a
rail service between Leicester and Burton is, at best, marginal,
although a number of ways to continue the feasibility study are
suggested
The jointly optimal inflation tax, income tax structure, and transfers
The welfare-maximizing income tax structure, rate of money creation, and amounts of intergenerational transfers are jointly determined for given rates of government consumption. When government consumption is zero, it is found for the parameter values examined that the income tax structure is progressive, the rate of money change is negative, and positive transfers are made to the old. As government consumption increases, the tax structure's progressivity declines and turns increasingly regressive, the rate of money change rises, and transfers decrease. It is found that the bulk of the increase in government consumption is optimally financed by a cut in transfers.Expenditures, Public ; Income tax
Comments on dual-mode nuclear space power and propulsion system concepts
Some form of Dual-Mode Nuclear Space Power & Propulsion System (D-MNSP&PS) will be essential to spacefaring throughout teh solar system and that such systems must evolve as mankind moves into outer space. The initial D-MNPSP&PS Reference System should be based on (1) present (1990), and (2) advanced (1995) technology for use on comparable mission in the 2000 and 2005 time period respectively. D-MNSP&PS can be broken down into a number of subsystems: Nuclear subsystems including the energy source and controls for the release of thermal power at elevated temperatures; power conversion subsystems; waste heat rejection subsystems; and control and safety subsystems. These systems are briefly detailed
