The Calvo pricing model that lies at the heart of many New Keynesian business cycle models has been roundly criticized for being inconsistent both with time series data on inflation and with micro-data on the frequency of price changes. In this paper I develop a new pricing model whose structure...

The majority of academic research on central bank communication has analysed a central bank’s audience as a single group. Analyses, especially empirical research have focused almost exclusively on a central bank’s interaction with the financial markets, facilitated by the...

Mankiw and Reis (2002) propose the Sticky Information Phillips Curve as an alternative to the standard New Keynesian Phillips Curve, to address empirical shortcomings in the latter. In this paper, a Sticky Information Phillips curve for South Africa is estimated, which requires data on...

This paper follows work by Choi, Kim and O’Sullivan (2011), but deviates from their analysis by looking at the relative price variability (RPV) of selected components of the consumer price index (CPI) rather than an aggregate measure. The purpose of this work is to analyse which...

I study the implications of learning by doing in production for optimal monetary policy using a basic New Keynesian model. Learning-by-doing is modeled as a stock of skills that accumulates based on past employment. The presence of this learning-by-doing externality breaks the ’divine...

In this paper we investigate the likelihood of a proposed monetary union in the Southern African Development Community (SADC) being successful from the viewpoint of the Generalised Purchasing Power Parity (GPPP) hypothesis and optimum currency area (OCA) theory. We apply Johansen’s...

Measures of core inflation convey critical information about an economy. They have a direct effect on the policy-making process, particularly in inflation-targeting countries, and are utilized in forecasting and modelling exercises. In South a Africa the prices indices on which inflation is...

This paper develops a new index of economic uncertainty for South Africa for the period 1990-2014 and analyses the macroeconomic impact of changes in this measure. The index is constructed from three sources: (1) Disagreement among professional forecasters about macroeconomic conditions using...

In this paper we investigate the role of inflation rates in determining economic growth in fifteen sub-Saharan African countries, which are all members of the Southern African Development Community (SADC), between 1980 and 2009. The results, based on panel time-series data and analysis, suggest...
