M.Comm. / The aim of this dissertation is to undertake an empirical study of the determinants of the Phillips curve for South Africa (SA). The work will be concentrated on the relationship between inflation (or wage inflation) and unemployment in SA from 1980 to 1998 with a particular focus on the behaviour of the Non Accelerating Inflation Rate of Unemployment (NAIRU). Given the importance of the NAIRU in formulating monetary policy, it will be therfore be appropriate to analysed this parameter. The NAIRU tends to perform differently in the face of price and wage inflation and therefore it has been found wise to divide the model into two categories. Price/unemployment model. Wage/unemployment model. The first model will be referred to as the Price-Phillips curve where as the second will usually be referred to as the Wage-Phillips curve. Models of Price-Phillips curve and Wage-Phillips curve are valuable tools for policy makers for a number of different purposes. In its original form the wage (or price) — unemployment relationship presents politicians with a list of different trade — offs to choose between inflation and unemployment. The trade-off seems to suggest that policy makers could choose a specific inflation-unemployment combination by controlling aggregate demand. This clearly points out that the trade-off postulated in the Phillips curve can be an usefull tool for monetary policy.

Thesis (M.Com. (Development Theory and Policy))--University of the Witwatersrand, Faculty of Commerce, Law and Management, School of Economic and Business Sciences, 2015. / Food price inflation has been an important subject of debate internationally since 2008. This sharp increase in food prices experienced during 2008 lead to intense research into the causes, dynamics and responses to this particular instance of food price inflation. The international literature attributed food price inflation to such factors as climate change, increases in energy costs and speculative activity in financial markets for agricultural commodities. This research report undertakes a review of the measurement of food price inflation in South Africa, broadly assessing how it is to be linked to the poor in South Africa. The research report focuses on the work of institutions concerned with the measurement of food price inflation in South Africa. Different methodologies of identifying foods as food staples are looked at. Food prices and trends are analysed using CPI data from January 2008 until October 2008, using selected consumer price index series from Statistics South Africa. The research report finds that the institutions studied show evidence of that higher food price inflation is correlated with demographic markers of poverty, although the traditional measure, the CPI, does not suggests that this is very extensive. This, it is argued, is due to the calculation methodologies used in the published CPI, and the data period. The research report then ends with an overview of the political economy of food in South Africa, thereby makes recommendations as to why the measurement of food price inflation is important for the poor.

A Dissertation submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Master of Science, 2012. / The purpose of this study is to investigate if the International Comparison Program (ICP) methodology could be used to examine the different buying power (worth) of the currency on the same products or goods amongst South African provinces. The method will be tested on the Consumer Price Index (CPI) food data collected from January 2006 to December 2006 from the main cities in the provinces. The food basket is obtained via the Income and Expenditure Survey (IES), which is generally updated every 5 years. South Africa (SA) has disparities and differentials in economic indicators such as the CPI, Gross Domestic Product and employment, amongst the provinces which are caused by among other things geographic set-up, urbanisation, inflation rates, and expenditure patterns. We use the monthly data to do an inter-provincial comparison of food prices by deriving annual purchasing power parities (PPPs) for each of the provinces, using the Country Product Dummy (CPD) method recommended as best practice by the World Bank. The CPI data is validated using the SEMPER software developed by the African Development Bank (AfDB). The validated data is examined for variability over the months and between the provinces using Analysis of Variance. Significant price differences are found for various products over the months and between provinces. The validated data was used to compute PPPs at the group and basic heading level. PPPs were investigated for differences in the provinces on grouped level of food products using Analysis of Variance. The reliability of PPPs between provinces is investigated both at grouped and basic heading level of products using the Cronbach-alpha statistic. The results show that there are no significant variations in PPPs across provinces. This could be due to the similar business opportunities or developments in the provinces or due to the aggregation of prices from the individual product (basic heading) to the main product group level. This implies that the cost of the food basket is the same across provinces.

Thesis submitted in fulfilment of the requirements for the degree of Doctor of Philosophy in the FACULTY OF COMMERCE LAW AND MANAGEMENT SCHOOL OF ECONOMICS AND BUSINESS SCIENCES at the UNIVERSITY OF THE WITWATERSRAND / The design and implementation of the monetary policy in South Africa has been based on the idea of a trade-off between inflation and output growth. However, there is no consensus among empirical investigations on the existence of Phillips curve in the present times. While the South African Reserve Bank (SARB) has instrument independence, it does not have goal independence, which implies that there is coordination between the monetary policy and other macroeconomic policies. Thus, if the SARB objectives are in line with the other policy objectives, there should be a relationship between monetary variables and real variables. This therefore shows that in the long-run, monetary policy cannot single-handedly bring about both sustained economic growth and employment creation (SARB, 2014). Thus this study explored inflation dynamics in South Africa by using the Hybrid new Keynesian Phillips curve (HNKPC) and the augmented Gordon’s models. The study firstly estimated the Hybrid new Keynesian Phillips curve model with a view to determine whether Phillips curve exists and ascertain whether the backward-looking or forward-looking components drive inflation dynamics in South Africa using OLS and GMM estimation techniques. The results show that the Phillips curve does not exist in South Africa using various measures of demand-side variable. These findings are robust across estimation methodologies as well as different measurements of inflation expectations and data frequency. While the findings indicated that economic agents in South Africa are both rational and adaptive in predicting inflation, the results clearly showed the dominance of forward looking component over the backward looking element in driving inflation. Secondly, given the focus of the South African monetary authority in maintaining stable inflation rates and the fact that monetary policy need to go hand-in-hand with other policies in order to ensure stable inflation and economic growth (Gruen, Pagan and Thompson, 1999), this study considered the expanded Gordon’s model with a particular focus on how fiscal policy determines the inflation process in South Africa. The purpose of the Gordon’s chapter is to verify the existence or non-existence of Phillips curve in an expanded model, within the context of an augmented “triangle” model while including the monetarist and fiscal side variables, thereby checking whether the PC relationship of recent studies is robust to model specification. Thus, the augmented Gordon’s model was estimated using a holistic approach of including the fiscalist, monetarist and the structuralist schools of thought, using the Vector autoregressive (VAR), vector error correction model (VECM) and innovation accounting techniques. The results confirm the non-existence of PC whereby output growth maintained a negative relationship with inflation rate, signifying no trade-off despite the expanded specification, while the results from output-gap model are inconclusive. Further results showed that the demand-side, fiscal factors and some of the structural variables contribute more to the inflation dynamics in South Africa. Thus the changes in inflation rate are as a result of changes in output growth, government deficit, electricity price and exchange rate. The results confirmed that the Fiscal Theory of the Price Level (FTPL) applies to the South African economy, whereby not only monetary policies should be considered in controlling inflation, but also fiscal policies. On the other hand, the importance of the determinants of inflation rate is not sufficient in observing the inflation dynamics in South Africa; therefore, this study concluded by investigating the level at which inflation becomes detrimental to output growth. In the context of the low levels of economic growth and high levels of unemployment in South Africa, the study analysed the output growth implications of the inflation targeting monetary policy of the South African Reserve Bank that targets an inflation band between three and six percent. Using the Threshold Autoregressive (TAR) and the Sample Splitting Threshold Regression (SSTR) techniques, this study investigated the nonlinear inflation-growth nexus in South Africa with the purpose of identifying the inflation rate band that optimize output growth. The results showed that South Africa is able to accommodate a higher level of inflation beyond the current inflation target band by increasing the band to between seven and nine percent in order to enhance output growth. Our findings support the argument of studies that indicate that moderately higher inflation rate will not be harmful to the economy. / MT2017

Thesis (M. Com. (Economics)) -- University of Limpopo, 2015 / South Africa is among a number of countries that have adopted inflation targeting as their monetary policy framework since 1990. This policy was adopted in the year 2000 in South Africa, and there have been a growing number of concerns about the effects of inflation targeting on economic growth in South Africa. The main purpose of this study is to determine these effects of inflation targeting on economic growth in South Africa. In this paper, the author used co-integration and error correction model to empirically examine the long-run and short-run dynamics of inflation targeting effects on economic growth. A final conclusion that inflation targeting does not have significant negative effects on economic growth is drawn from two interesting results. Firstly, there is an insignificant negative relationship between inflation targeting and economic growth. Secondly, the influence that inflation targeting has on the relationship between the lag of inflation and economic growth is also insignificant. These findings have important policy implications. Therefore, the critique that the SARB achieves relatively low inflation at the expense of low economic growth is a misconception. This led to the conclusion that the SARB should maintain its monetary policy framework of inflation targeting which has helped it to reduce inflation.

This research was conducted to evaluate the adoption of inflation targeting in South Africa as a strategy to maintain price stability. The research was based on the period prior to inflation targeting and the period of inflation targeting. The comparison was done to determine if the Reserve Bank was on the right track in adopting inflation targeting. The research was conducted to determine if there is any correlation between CPIX inflation and other factors affecting inflation. The factors investigated were: food inflation, transport inflation, housing inflation, exchange rate, Brent crude oil, money supply, and the current account deficit to the GDP. The correlation studies were conducted during the same period and when the factors were lagged up to eight quarters. The correlations were statistically tested at 5% significant level. The results show that the period of inflation targeting has a strong correlation compared to the period prior to inflation targeting, when compared during the same time period and lagged time period. / Thesis (MBA)-University of KwaZulu-Natal, 2006.

The effectiveness of monetary policy in achieving its macroeconomic objectives such as price stability and economic growth depend on the monetary policy tools that are implemented by the Central Bank. Monetary aggregates are one of the tools that have been used as indicators of economic activity and as intermediate targets to achieve these economic objectives. Until recently, monetary aggregates have been questioned and criticised on their usefulness in monetary policy. This has been attributed to the economic, financial and technological developments that have distorted the relationship between monetary aggregates and major macroeconomic variables. This study investigates the relevance of monetary aggregation by comparing the traditional simple sum and Divisia index monetary aggregates which was constructed for the first time for South Africa using the Tornquist-Theil method. The Polynomial Distributed Lag model is employed to compare the performance of these monetary aggregates using their relationship with inflation and manufacturing index. Furthermore, the aggregates are compared in terms of their controllability and information content. Overall, the study found a very strong relationship between inflation and all the monetary aggregates. However, more specifically the results suggested that the Divisia indices are superior to the simple sum in terms of predicting inflation. The evidence further suggests that the Divisia aggregates provide higher information about inflation than the simple sum aggregates. Regarding the controllability of the monetary aggregates, the findings suggest that the monetary authorities can hardly control the monetary aggregates using monetary base. Finally, the relationship between manufacturing index and all the monetary aggregates was very weak.

The study examines exchange rate volatility and inflation in South Africa over the period of 1987- 2012 using annual data. With the use of VAR, ADF unit root testing and Johansen for cointegration the study examines the relationship between exchange rate volatility and inflation in South Africa. The study also examines other variables, which are Money Supply, Trade Openness, Real Interest Rate and Real Gross Domestic Product (RGDP), if they had an impact on inflation and had contributed significantly to inflation during the period under review. All macroeconomic variables were identified to have an impact on inflation in the long-run. Exchange rate volatility was identified as the main variable that had substantial impact on inflation rate. The study recommended the current system used by the authorities was working well, as they can pursue a countercyclical macro policy, but also continue to manage the float by intervening to stabilize the exchange rate. The reason for this recommendation was that because one of the advantages of floating exchange rate is freeing internal policy, with a floating exchange rate, balance of payments disequilibrium would be rectified by a change in the external price of the currency. However, with a fixed rate, curing a deficit could involve a general deflationary policy resulting in unpleasant consequences for the whole economy such as unemployment.
