There is widespread disagreement about the role of housing wealth in explaining consumption.  This paper exploits liquid and illiquid wealth time series from household balance sheet data for South Africa, previously constructed by the authors, to explain fluctuations in the ratios of...

This paper incorporates limited asset markets participation in dynamic general equilibrium and develops a simple analytical framework for monetary policy analysis. Aggregate dynamics and stability properties of an otherwise standard business cycle model depend nonlinearly on the degree of asset...

In countries with credible inflation targeting, it seems plausible to suggest that instead of forming a rational expectation, some firms (inflation-targeters) might simply expect future inflation to always equal its target. This paper analyses the implications of this for optimal monetary policy...

The consumption behaviour of UK, US and Japanese households is examined and compared using a modern Ando-Modigliani style consumption function.  The models incorporate income growth expectations, income uncertainty, housing collateral and other credit effects.  These models therefore capture...

Standard open economy models predict that openness to trade should exert a positive effect on the slope of the output-inflation tradeoff, or Phillips curve, but such a proposition finds very little support in the existing empirical literature. We propose a new test of this hypothesis based on...

A number of thoretical models predict that the slope of the Phillips curve increases with trade openness, but cross-country studies provide little evidence for such a correlation. We highlight two reasons for this finding. Firstly, the strength of the relationship may depend on the extent of...

In this paper we introduce a small Keynesian model of economic growth which is centered around two advanced types of Phillips curves, one for money wages and one for prices, both being augmented by perfect myopic foresight and supplemented by a measure of the medium-term inflationary climate...

We build a 4-equation model of the inflation process in South Africa (which has recently adopted inflation targeting), including the exchange rate, consumer prices, producer price, and import prices. This provides useful information on the speed and extent of exchange rate pass-through, and...

This paper studies the efficient taxation of money and factor income in intertemporal optimizing growth models with infinite horizons, transaction costs technologies and flexible prices.  Second-best optimality calls for a positive inflation tax and a non-zero capital income tax when there are...
