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...

Infrequent price changes at the firm level are now well documented in the literature. However, a number of issues remain partly unaddressed. This paper contributes to the literature on price stickiness by investigating the lags of price adjustments to different types of shocks. We find that...

Thanks to recent findings based on survey data, it is now well known that firms differ from each other with respect to their price-reviewing strategies. While some firms review their prices at fixed intervals of time, others prefer to perform price revisions in response to changes in economic...

When the zero lower bound on nominal interest rates binds, monetary policy cannot provide appropriate stimulus. We show that in the standard New Keynesian model, tax policy can deliver such stimulus at no cost and in a time-consistent manner. There is no need to use inefficient policies such as...

This paper constructs a number of possible core measures of annual inflation using Singular Spectrum Analysis (SSA). Annual inflation is decomposed into its trend, oscillating and noise components in order to develop an understanding of the trend and cyclicality in South African headline...

In this paper we investigate the role of financial development, or more wide-spread access to finance, in generating economic growth in four Latin American countries between 1980 and 2007. The results, based on panel time-series data and analysis, con.rm the Schumpeterian prediction which...

It is believed that a shock, common to a set of countries with identical fundamentals, has identical outcomes across countries. We show that in general, when specialization in production is such that a common shock creates a missing role for labor mobility across countries, the terms of trade of...

We show how monetary aggregates can be usefully incorporated in forecasts of inflation. This requires fully disregarding the high-frequency fluctuations blurring the money/inflation relation, i.e., the projection of inflation onto monetary aggregates must be restricted to the low frequencies....

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...
