AFTER MUGABE GOES – THE ECONOMIC AND POLITICAL RECONSTRUCTION OF ZIMBABWE

This Presidential address briefly outlines the developments in Zimbabwe since independence in 1980 leading up to the current political and economic crisis. The Zimbabwean situation is assessed within the conceptual framework of patrimonialism and predatory states. The origins of the Zimbabwean crisis are then analysed in their economic and political context leading to an eventual “fragile” or “failed” state. Evaluation of the crisis suggests that institutional damage has proceeded to the point at which only large scale economic and political reconstruction offers sustainable long term solutions, irrespective of when President Mugabe leaves office. The address concludes with an examination of the regional implications for Southern African Development Community – as well as the role of the global community – and outlines some of the core components of any reconstruction process‐to‐be in Zimbabwe.     

FORECASTING THE SOUTH AFRICAN ECONOMY WITH VARs AND VECMs

The paper develops a Bayesian Vector Error Correction Model (BVECM) of the South African economy for the period 1970:1‐2000:4 and forecasts GDP, consumption, investment, short and long term interest rates, and the CPI. We find that a tight prior produces relatively more accurate forecasts than a loose one. The out‐of‐sample‐forecast accuracy resulting from the BVECM is compared with those generated from the Classical variant of the VAR and VECM and the Bayesian VAR. The BVECM is found to produce the most accurate out of sample forecasts. It also correctly predicts the direction of change in the chosen macroeconomic indicators.     

CYCLICAL UNEMPLOYMENT AND CYCLICAL OUTPUT: AN ESTIMATION OF OKUN'S COEFFICIENT FOR SOUTH AFRICA

Persistently high unemployment in South Africa, especially in the face of improved economic conditions since 1994, begs the question: Does unemployment in South Africa respond to changes in output? Okun's law refers to the inverse relationship that exists between cyclical output and cyclical unemployment. This paper estimates Okun's coefficient for the South African economy, using annual data from 1970‐2005. Output and unemployment are decomposed into their trend and cyclical components, using a variety of detrending methods. The presence of structural breaks in Okun's relationship is also investigated, while cointegration analysis was also considered. Evidence of a statistically significant relationship between cyclical output and cyclical unemployment are found in both symmetric (estimates range from ?0.77 to ?0.16) and asymmetric (estimates range from ?0.77 to ?0.18) specifications of Okun's law, irrespective of the detrending technique. However, cyclical unemployment constitutes only a relatively small fraction of total (observed) unemployment, which implies that a more expansionary macroeconomic policy stance might only have a limited impact on total unemployment in South Africa.     

A BVAR MODEL FOR THE SOUTH AFRICAN ECONOMY

The paper develops a Bayesian vector autoregressive (BVAR) model of the South African economy for the period of 1970:1‐2000:4 and forecasts GDP, consumption, investment, short‐term and long term interest rates, and the CPI. We find that a tight prior produces relatively more accurate forecasts than a loose one. The out‐of‐sample‐forecast accuracy resulting from the BVAR model is compared with the same generated from the univariate and unrestricted VAR models. The BVAR model is found to produce the most accurate out of sample forecasts. The same is also capable of correctly predicting the direction of change in the chosen macroeconomic indicators.     

FORECASTING THE SOUTH AFRICAN ECONOMY WITH GIBBS SAMPLED BVECMs

The paper uses the Gibbs sampling technique to estimate a heteroscedastic Bayesian Vector Error Correction Model (BVECM) of the South African economy for the period 1970:1‐2000:4, and then forecasts GDP, consumption, investment, short and long term interest rates, and the CPI over the period of 2001:1 to 2005:4. We find that a tight prior produces relatively more accurate forecasts than a loose one. The out‐of‐sample‐forecast accuracy resulting from the Gibbs sampled BVECM is compared with those generated from a Classical VECM and a homoscedastic BVECM. The homoscedastic BVECM is found to produce the most accurate out of sample forecasts.     

EQUALITY AND PERSONAL INCOME TAX – THE CLASSICAL ECONOMISTS AND THE KATZ COMMISSION

In reforming South Africa's personal income tax system, the Katz Commission relied heavily on equality and the constitution. It did not, however, explain its understanding of the meaning of equality in general or equality of taxation in particular, being content merely to mechanically remove what it perceived to be discriminatory words in the legislation. The meaning of equality of taxation on the other hand, was thoroughly debated by the classical economists. This article explains the classical economists' meaning of equality of taxation and demonstrates that the classical system of equality and that achieved by implementing the Katz Commission's recommendations are vastly different. In particular lower income groups, single income households and families are considerably worse off.     

THE EQUITY PREMIUM AND RISK-FREE RATE PUZZLES IN A TURBULENT ECONOMY: EVIDENCE FROM 105 YEARS OF DATA FROM SOUTH AFRICA

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 returns six to eight percentage points above bonds and cash, and at the 20-year horizon, an investor would not have experienced a single negative realised equity premium over the entire 105-year period we examine. Yet the maximum equity premium rationalised by the consumption-based model is 0.4%. The canonical macro-financial model closely matches the average risk-free rate, using realistic parameters for the coefficient of risk aversion and a positive rate of time preference.     

A SMALL-SCALE DSGE MODEL FOR FORECASTING THE SOUTH AFRICAN ECONOMY

This paper uses a version of Hansen's (1985) Dynamic Stochastic General Equilibrium (DSGE) model to forecast the South African economy. The calibrated model, based on annual data over the period of 1970‐2000, is used to generate one‐ to eight‐quarters‐ahead out‐of‐sample forecast errors for the period of 2001:1 to 2005:4. The forecast errors are then compared with the unrestricted versions of the Classical and Bayesian VARs. A Bayesian VAR with relatively loose priors outperforms both the classical VAR and the DSGE model.     

FOREIGN TRADE, COMMERCIAL POLICIES AND THE POLITICAL ECONOMY OF THE SONG AND MING DYNASTIES OF CHINA

The paper presents a framework to explore the trade-off between pro-authority and pro-efficiency foreign trade policy. The former is exemplified by the tributary foreign trade system in Imperial China, while the latter by the government-supervised private foreign trade. In the Song Dynasty (960–1276), a strong external enemy compelled the monarchy to choose a pro-efficiency trade policy to finance the army, whereas during the early Ming Dynasty (1368–1644) when China was strong a pro-authority trade policy was favoured. During the late Ming, as the dynasty weakened, accompanied by external threats and internal mismanagement, the imperial government once again chose a pro-efficiency trade policy.     

GROWTH,EMPLOYMENT AND UNEMPLOYMENT IN SOUTH AFRICA

The high rate of unemployment in South Africa stands out in an otherwise vastly improved set of macroeconomic fundamentals compared with the situation in the early 1990s. One might be tempted to argue that by this single indicator alone, the government's macroeconomic policies have been a failure. This paper explains why jumping to such a conclusion would be a mistake. Annual time series data on total formal sector employment is constructed dating back to 1946. The relationship between economic growth and formal sector employment is then measured and changes in the employment coefficient over time are described. The employment coefficient was found to be relatively stable, with a long‐term average value of 0.5. It returned to this value after a short‐lived collapse in the mid‐1990s. It is concluded that the main reason for the persistently high and rising rates of unemployment in South Africa since the mid 1990s was the very large increase in the labour force and not a historically deficient growth or employment performance of the economy.     

Eastern Germany and the conflict between wage adjustment,investment, and employment: A numerical analysis

Eastern Germany and the Conflict between Wage Adjustment, Investment, and Employment: A Numerical Analysis. — In this paper, some light is shed on the dynamics of the adjustment process in eastern Germany by studying the linkages between the dynamics of wage adjustment, investment, and employment. An extended dynamic investment model, which includes adjustment costs for capital and revision costs for investment, is presented. This model is specified according to the east German economy and analyzed numerically by an optimization method based on direct collocation. Results are obtained for the time horizon of adjustment and for the implications of different wage strategies on the path of investment and employment.     

FORMAL–INFORMAL ECONOMY LINKAGES AND UNEMPLOYMENT IN SOUTH AFRICA

South Africa's high unemployment and small informal economy has been attributed to barriers to entry in informal labour markets. We develop a general equilibrium model based on a typology of informal activities that captures formal/informal linkages in product and labour markets. Simulations reveal that trade liberalisation increases formal employment, hurts informal producers, and favours informal traders and may explain the dominance of traders instead of producers. Wage subsidies also raise employment but further heighten competition for informal producers. Cash transfers favour informal employment, albeit with a fiscal burden. Results confirm the role of formal/informal linkages and product markets in explaining policy outcomes.     

THE EUROMARKETS AND THE NEW ZEALAND GOVERNMENT IN THE 1960S

The rapid development of the Euromarkets and the more gradual opening of the West German and other capital markets to external borrowers were significant events in the reglobalisation of financial markets beginning in the 1960s. Finding it increasingly difficult to borrow in the domestic British and US capital markets, the New Zealand government sought to take advantage of the Euromarkets. As well as providing an antipodean perspective on the early Euromarkets, this paper comments on developments in the City of London in the 1960s, and outlines the process by which a relatively inexperienced borrower set about building a communicating infrastructure that enabled relationships to be forged with overseas financial institutions.     

THE CHANGING VOLATILITY OF THE SOUTH AFRICAN ECONOMY

During the last decade economic literature explored the presence of and reasons for what became known as “the great moderation” in the US and other G7 countries. “The great moderation” describes the decrease in economic volatility experienced in many of the G7 countries. This paper finds that in South Africa volatility is also not constant (it even finds that there are autoregressive conditional heteroskedastic effects present) and that volatility also decreased, particularly since 1994. Following the literature, the paper explores several reasons for this decrease and finds that smaller shocks, better monetary policy and improvements in the financial sector that place less liquidity constraints on individuals and allow them to manage their debt better are some of the main reasons for the reduction in the volatility of the South African economy. The literature on the G7 also suggests that better inventory management contributed to the lower volatility. However, this seems not to be true for South Africa.     

AN OPEN ECONOMY NEW KEYNESIAN DSGE MODEL OF THE SOUTH AFRICAN ECONOMY

In this paper an open economy New Keynesian model of the South African economy is presented. The model is constructed to provide for incomplete pass-through of exchange rate changes, external habit formation, partial indexation of domestic prices and wages to past inflation, and staggered price and wage setting. Furthermore, the model is estimated using Bayesian techniques on South African domestic and trade partner data for the period 1990Q1 to 2007Q4. The estimated model is analysed by means of impulse response functions.     

EXCHANGE RATES AND EMPLOYMENT

The analysis of exchange rates and employment has received scant attention in development economics. This is surprising, since there appears to be a number of well-defined transmission channels through which exchange rates impact on employment. In South Africa this is particularly important given the rand's higher volatility relative to other emerging economies. The main focus of this paper is to give an overview of the transmission channels through which exchange rates affect employment and to discuss the standard methodological approach to conceptualising the impact of exchange rates on employment. Given the sector-specific impact of exchange rates which are conditioned by industry characteristics, such as the degree of external orientation, there will always be winners and losers in the face of a currency shock. This means the full impact of exchange rates on employment can only be dealt with in an economy-wide framework. Results from a computable general equilibrium (CGE) model are presented to demonstrate that even in a country with unreliable employment data such as South Africa, one can still analyse exchange rate and employment issues.     

A HISTORICAL PERSPECTIVE ON INDIGENOUS SOCIOECONOMIC OUTCOMES IN AUSTRALIA, 1971–2001

Current debate in Indigenous affairs in Australia often involves the assertion that the last 30 years has been a period of policy failure. This article examines trends across a number of socioeconomic outcomes for Indigenous Australians from the 1967 referendum to the present, using census data. Overall, there has been steady, although not spectacular improvement in outcomes over time. These improvements are especially marked for education, which was coming from an exceptionally low base. This finding is somewhat at odds with the common perception of the 'failure' of Indigenous policy.
