METROPOLITAN HOUSE PRICES IN SOUTH AFRICA: DO THEY CONVERGE?

The question this paper investigates is whether or not different metropolitan areas each constitute a separate housing market or whether or not there is a single South African housing market. Theory on the Law of One Price suggests that if products or geographic areas belong in the same market, their absolute prices must converge, so that their relative prices are stationary. By using cross-sectional time series data of five metropolitan areas, the paper tests for the Law of One Price by applying the Im, Pesaran and Shin panel unit root test. The paper finds strong evidence of convergence in large middle-segment house prices and weaker support for convergence in medium middle-segment house prices. In addition, the paper finds no evidence for convergence in small middle-segment house prices. This suggests the existence of a national market for large and possibly middle-segment houses in metropolitan areas, but separate metropolitan markets for small middle-segment houses. In addition, the paper estimates the speed of convergence and finds that large middle-segment house prices converge within two to seven quarters, while the speed of convergence for medium middle-segment house prices in three of the five areas is five to eight quarters.     

SHOULD SOUTH AFRICA HAVE A FISCAL RULE?

Over the past three decades many countries have struggled to find solutions to their persistent public sector deficits. For some the solution to this problem seemingly became the adoption of fiscal rules. This paper considers the applicability of one such rule, namely the output‐sensitive deficit rule of Taylor, and in particular its applicability to South Africa. The paper shows that its applicability in developing countries such as South Africa might be limited due to higher output volatility that may cause output‐sensitive deficit rules such as the Taylor rule to become more volatile. Such volatility in the deficit/GDP ratio may cause fears that government may not be able to maintain the stability of the debt/GDP ratio, thereby again introducing fiscal unsustainability. To address this problem the paper augments the Taylor rule to reduce the volatility in the public debt/GDP ratio and demonstrates how these rules would have performed in South Africa. It concludes that the augmented fiscal rule might contribute to both fiscal sustainability and economic stability in South Africa.
