The U.S. economy appears to have experienced a pronounced shift toward higher productivity over the last five years or so. We wish to understand the implications of such shifts for the structure of optimal monetary policy rules in simple dynamic economies. Accordingly, we begin with a standard...

We study how determinacy and learnability of global rational expectations equilibrium may be affected by monetary policy in a simple, two country New Keynesian framework. We seek to understand how monetary policy choices may interact across borders to help or hinder the creation of a unique REE...

We study how determinacy and learnability of worldwide rational expectations equilibrium may be affected by monetary policy in a simple, two-country, New Keynesian framework under both fixed and flexible exchange rates. We find that open economy considerations may alter conditions for...

We wish to understand the implications of recent shifts in US productivity for the structure of optimal monetary policy rules. Accordingly, we augment a standard inflation targeting model in which a forward-looking version of the Taylor rule constitutes the optimal monetary policy with regime...

We study how determinacy and learnability of global rational expectations equilibrium may be affected by monetary policy in a simple, two country, New Keynesian framework. The two blocks may be viewed as the U.S. and Europe, or as regions within the euro zone. We seek to understand how monetary...

This study assesses the behaviour of credit extension over the economic cycle to determine its usefulness as a reference guide for implementing the countercyclical capital buffers for financial institutions in South Africa. The study finds that the common reference guide for implementing the...

This paper develops an estimable hybrid model that combines the micro-founded DSGE model with the flexibility of the theoretical VAR model. The model is estimated via the maximum likelihood technique based on quarterly data on real Gross National Product (GNP), consumption, investment and hours...

This paper examines the relationship between in‡ation and in‡ation expectations of analysts, business, and trade unions in South Africa during the inflation targeting (IT) regime. We consider inflation expectations based on the Bureau of Economic Research (BER) quarterly survey observed...

Central bankers generally prefer to reduce inflation gradually. We show that a central bank may try to convince the private sector of its commitment to price stability by choosing to reduce inflation quickly. We call this "teaching by doing". We find that allowing for teaching by doing effects...

n this paper we incorporate the term structure of interest rates in a standard inflation forecast targeting framework. We find that under flexible inflation targeting and uncertainty in the degree of persistence in the economy, allowing for active learning possibilities has effects on the...
