Seit einigen Monaten wird in der Fachliteratur und den Medien eine teils heftige Diskussion um die sogenannten Target2-Salden geführt. Vordergründig geht es dabei um ein Verrechnungssystem der Notenbanken der Eurozone. Laut Hans-Werner Sinn, der die Debatte angestoßen hat, haben die in diesem...

The paper evaluates the theoretical literature on public pension schemes. First, the terms pay-as-you-go and capital reserve are made precise. These two systems are then compared, followed by a consideration of their efficiency properties. Thereafter conversion policies are discussed.

Public pension schemes can be designed either as capital reserve systems or as unfunded (or pay-as-you-go) schemes. In the literature it has been alleged that unfunded schemes are intergenerationally efficient in Pareto's sense. Here we show that this holds only if contributions to the system...

In recent contributions, Weizsäcker (2014) and Summers (2014) maintain that mature economies accumulate too much capital. They suggest large and lasting public deficits as a remedy. This paper argues that overaccumulation cannot occur in an economy with land. It presents novel data of aggregate...

While the target federal funds rate represents a policy instrument, the effective federal funds rate is determined in a competitive interbank market. The paper proposes a theory of its determination. This yields a specific term structure of interest rates, an account of why the money multiplier...

This paper examines five possible explanations for the Great Recession of 2008 and 2009, using data for the United States and the eurozone. Of these five hypotheses, four are not supported by the data, while the fifth appears reasonable.

Japan has been in a benign liquidity trap since 1990. In a benign liquidity trap, interest rates approach zero, prices decline, and monetary policy is ineffective but output and employment perform decently. Such a pattern contradicts traditional macro theories. This paper introduces a monetary...
