The paper argues that, from a dynamic efficiency perspective, intersections of factor price frontiers are irrelevant to the choice of techniques. Because every change in technique involves a temporary loss or gain in both profit and per capita consumption within the transition period, its...

The aim of this paper is to develop a methodology for measuring the exercise of potential market power in liberalized electricity markets. We therefore investigate producer behavior in the context of electricity pricing with respect to fundamental time-dependent marginal cost (TMC), i.e. CO2-...

An optimal taxation approach is employed to compare a proportional income tax with a death tax within a simple lifetime-cycle-model. The impact of both taxes is discussed concerning consumption, leisure, savings, and inheritance. It is shown that the income tax generally leaves the tax payer...

A general model of intertemporal consumption choice is developed, following Samuelson`s 1958 OLG-approach. The efficiency properties of the model are discussed with and without the introduction of durable goods, of productive capital, and fiat money. It is shown that the criterion of golden rule...

A simple OLG-model is developed, where housing is the only consumption good and saving is either in terms of financial assets or in terms of owner-occupied or rented dwellings. It is shown that, while without taxes optimal consumption plans and maximum utility are the same for both the tenant...

The so-called purchasing power argument of wages (PPA), suggesting that rising wages could increase employment instead of reducing it, is examined within a general theoretical framework. While the demand side is modelled by means of a path-dependent Keynesian model with a Kaldorian saving...
