We examine the high-frequency response of the rand-dollar nominal rate within ten-minute intervals around five minutes before, five minutes after) official inflation announcements, and show that the rand appreciates (respectively, depreciates) on impact when inflation is higher (respectively,...

Short-term interest rate processes determine the term-structure of interest rates in an arbitrage-free market, and are central to the valuation of interest-rate derivatives. We obtain parameter estimates and compare the empirical fit of alternative one-factor continuous-time processes for the...

This paper revisits the currency crises model of Aghion, Bacchetta and Banerjeee (2000, 2001, 2004), who show that if there exist nominal price rigidities and private sector credit constraints, and the credit multiplier depends on real interest rates, then the optimal monetary policy response to...

We analyze the returns to targeting the Australian, New Zealand, and South African currencies, through Japanese yen-funded speculation - with a particular focus on the South African rand, for which the carry trade is often seen as a source of exchange rate volatility. Targeting the rand through...

A nominal income target may provide credibility to a commitment to keep real interest rates exceptionally low, until a target output level is reached -–even if expected inflation rises in the interim–- in economies where nominal interest rates are effectively at the zero lower bound,...

This paper presents a overview and discussion of facts and research findings on South African equity, currency, bond and derivatives markets. It is not a comprehensive literature review, but rather an assessment of where we stand - how the markets have developed, how the main markets compare...

Microstructure aspects of nominal exchange rate determination are less relevant in countries with embryonic financial markets. In less-developed economies, trade in goods and services is a more significant driver of currency demand than financial market speculation or hedging; and central banks...

At what level does a currency’s volatility become ‘excessive’, in a concrete sense? Any claim that an exchange rate is excessively volatile needs a benchmark for ‘normal’variability. We compute variance bounds implied by exchange rate models as the norm, for a set of...

We implement a recursive out-of-sample method to examine anomalies-based ex-ante predictability in the cross-section of stock returns. We obtain a series of simulated out-of-sample returns, consistent with investors using only prior information when choosing predictor variables. We find that, by...

This paper presents a detailed empirical examination of the South African equity premium; and a quantitative theoretic exercise to test the canonical inter-temporal consumption-based asset-pricing model under power utility. Over the long run, the South African stock market produced average...
