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 reasons for the current financial crisis are analysed and a proposal for financing a bad bank is made. In particular, it is proposed to give the banks in trouble government zero bonds rather than cash in exchange for their toxic assets. The term of the zero bonds is determined individually...

This paper discusses the instrument of equalisation claims, which has successfully been used in two previous German debt crises as a method for stabilizing the balance sheets of financial institutions. A modern version of this method would swap temporarily illiquid assets for government bonds...

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...

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 model is developed which explains deep recessions like the recent crisis by a lack of economic confidence, going along with a high liquidity preference of both private households and the private banking system. Thus the paper argues for a new form of Keynesian policy, which rests on monetary...

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...

Walter Eucken was the head of the Freiburg school of economics, a circle of German ordoliberal scholars of the interwar period, whose thoughts were highly influential in the immediate post war period. Being disillusioned by what he called the age of experiments- the failure of both classical...

It has repeatedly been proposed to reduce conventional pay-as-you-go-systems to a base level, leaving advanced retirement provision for private funded systems. However, pay-asyou-go systems are, in a sense, one way roads, with no available Pareto efficient way out. The paper discusses a combined...
