I use my "Viking Village" macroeconomic model for examining the economic meaning of the so-called Target-balances in the EMU. While some authors like H.W. Sinn and Thomas Mayer interpret them as liabilities that must be redeemed and paid interest on, others like Marcel Fratzscher, Martin Hellwig...

A simple OLG model is used to show that the natural interest rate is superior to the golden rule. This remains valid with public goods, provided these are financed in an appropriate way. In order to preserve the natural interest rate, the so-called helicopter money appears to be more appropriate...

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...

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...

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...

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...

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 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...
