The theoretical determinants of maximum sustainable government debt are investigated using Diamond's overlapping generations model. A level of debt is defined to be 'sustainable' if a steady state with non-degenerate values of economic variables exists. We show that a maximum sustainable level...

This paper argues that a stable broad money demand for the euro area over the period 1980-2011 can be obtained by modelling cross border international portfolio allocation. As a consequence, model-based excess liquidity measures, namely the difference between actual M3 growth (net of the...

A monetary overlapping generations model with oligopolistic imperfect competition is constructed. In general, output and employment are below their full employment levels. Three alternative expectations hypotheses are used - 'adaptive', 'monetarist' and 'pure rational' - all of which ensure no...

The microeconomic foundations provided by the 'disequilibrium' macro-modelling approach of Barro-Grossman-Malinvaud are used to compare the performance of government spending and taxation as instruments of fiscal demand management in achieving a welfare optimum. Spending is successively treated...

A dynamic, stochastic optimizing macromodel with predetermined money wages and labour market monopoly power is used to examine the effect on current macroeconomic variables of a temporary increase in variability of the future money supply. As a benchmark, we show that under perfect wage-price...

A dynamic stochastic model of a small open monetary economy with infinitely-lived optimizing households is constructed. There are temporary nominal rigidities in the labour market, while in goods and asset markets prices are flexible. Optimizing behaviour in the foreign country is also modelled....
