THE ROLE OF PRIVATE CAPITAL INFLOWS AND THE EXCHANGE MARKET PRESSURE ON REAL EXCHANGE RATE APPRECIATION: THE CASE OF TURKEY

The aim of this paper is to investigate the role of different private capital inflows and the exchange market pressure (EMP) on the real effective exchange rate (REER) appreciation of the currency in Turkey. To that end, the paper first investigates the long‐run equilibrium relationship and then employs Granger causality analysis. Results of the bounds test for cointegration within the autoregressive distributed lag (ARDL) modelling approach of Pesaran et al. (2001 ) reveal level relationship between the diverse private capital inflows, EMP and REER. Granger causality analysis suggests that there is a unidirectional causality running from all the concerned private capital inflows and EMP to REER. The ARDL model shows first that the impact of bank liabilities and portfolio investment liabilities are almost equal, high and positive. Second, foreign direct investment and workers' remittances have a negative but statistically insignificant effect. Third, EMP mitigates REER appreciation of the currency in Turkey. The empirical results suggest that speculative portfolio investment liabilities but particularly bank liabilities with short maturities should be better managed; more flexibility should be introduced to the floating exchange rate regime to avoid loss of competitiveness related with capital inflows; whereas foreign direct investments and remittances should be encouraged.     

COPING WITH INFLATION AND EXCHANGE RATE SHOCKS IN THE SOUTH AFRICAN ECONOMY

Over the past ten years South Africa has moved to an increasingly open economy, characterised by a (relatively) low inflation and large and unpredictable movements in the prices of financial assets. One of these asset prices is the value of the South African currency. This volatility in the exchange rate has a direct impact on inflation. Using the interest rate as operational target, a central bank might ignore or underestimate the exchange rate transmission mechanism through which the economy is influenced. This paper proposes a Monetary Conditions Index for South Africa that can be used as a policy rule or simply as an important information variable in conducting monetary policy under an inflation‐targeting regime with a volatile exchange rate.     

HIGH AND VARIABLE INFLATION: FURTHER EVIDENCE ON THE FRIEDMAN HYPOTHESIS

This note, employing a GARCH model, finds a positive and significant relationship between the level and variability of inflation in South Africa in the period 1957:1‐2005:9. This provides evidence in support of Friedman's hypothesis that high inflation leads to more variable inflation.     

IMPLICATIONS OF REAL EXCHANGE RATE MISALIGNMENT IN DEVELOPING COUNTRIES: THEORY,EMPIRICAL EVIDENCE AND APPLICATION TO GROWTH PERFORMANCE IN ZIMBABWE

The influence of exchange rate signals in an economy is very powerful and often pervasive. Moreover, sustained real exchange rate overvaluation will, by distorting resource allocation away from productive activities, eventually lead to drastic adjustments of relative prices and reduction of aggregate economic growth. However, the direct theoretical and empirical link between exchange rate misalignment and macroeconomic indicators still remains to be fully understood. Nonetheless, empirical studies continue to make attempts to understand this relationship by exploring relationships that incorporate different measures of exchange rate misalignment in traditional growth regression models. Based on a behavioural equilibrium exchange rate derived measure exchange rate misalignment, this paper presents an empirical analysis of the relationship between real gross domestic product growth and real exchange rate misalignment for Zimbabwe. After controlling for other structural and policy variables, the main findings demonstrate that exchange rate misalignment exerts a negative and highly statistically significant impact on growth. Overall, the results lend support to the hypothesis that chronic real exchange rate overvaluation was a key fundamental behind the post‐2000 economic growth contraction in Zimbabwe.     

ON MEASURING THE EFFECT OF INFLATION UNCERTAINTY ON REAL GNP GROWTH

In this paper we re-examine the relationship between inflationuncertainty and total output. To properly specify an estimatingequation, we investigate the time series properties of two frequentlyused measures of inflation uncertainty. We fail to reject thehypothysis that each series has a unit root. However, the uncertaintymeasures are not cointegrated with output and relative oil prices.This means that the proper specification is in terms of differences.With this specification we find that an increase in inflationuncertainty growth reduces real GNP growth but, unlike earlierwork, we find that this effect is temporary. It is also unlikelythat an inflation uncertainty shock on its own could producea recession.     

ON THE RAND: DETERMINANTS OF THE SOUTH AFRICAN EXCHANGE RATE

This paper is an econometric investigation of the determinants of the real value of the South African rand over the period 1984‐2007. The results show a relatively good fit. As always with exchange rate equations, there is substantial weight on the lagged exchange rate, which can be attributed to a momentum component. Nevertheless, economic fundamentals are significant and important. This is especially true of an index of the real prices of South African mineral commodities, which even drives out real income as a significant determinant. An implication is that the 2003‐2006 real appreciation of the rand can be attributed to the Dutch Disease. In other respects, the rand behaves like currencies of industrialised countries with well‐developed financial markets. In particular, high South African interest rates raise international demand for the rand and lead to real appreciation, controlling also for a forward‐looking measure of expected inflation and a measure of default risk or country risk.     

SHORT‐RUN AND LONG‐RUN DETERMINANTS OF THE REAL EXCHANGE RATE IN MEXICO

This paper explores the real exchange rate behavior in Mexico from 1960 until 2005. Since the empirical analysis reveals that the real exchange rate is not mean reverting, we propose that economic fundamental variables affect its evolution in the long run. Therefore, based on equilibrium exchange rate paradigms, we propose a simple model of real exchange rate determination, which includes the relative GDP per capita, the real interest rates, and the net foreign assets over a long period of time. Our analysis also considers the dynamic adjustment in response to shocks through impulse response functions derived from the multivariate vector autoregressive (VAR) model.     

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.     

REAL AND DISTRIBUTIVE EFFECTS OF PETROLEUM PRICE LIBERALIZATION: THE CASE OF INDONESIA

The effect of higher petroleum prices on the aggregate price level, real growth, and income distribution is appraised within a multisector computable general equilibrium (CGE) model. A reduction in the government subsidy raises petroleum prices and production costs throughout the economy. Consumer demand, production, and income decline as output prices increase and consumer purchasing power decreases. The model is applied to and calibrated for Indonesia. The simulated results predict a slight increase in the price level and a slight decrease in output. An important result is that urban household groups will be the most significantly affected by the subsidy reduction.     

TRADE PATTERNS AND EXCHANGE RATE REGIMES: TESTING THE ASIAN CURRENCY BASKET USING AN INTERNATIONAL INPUT‐OUTPUT SYSTEM

This paper aims at analyzing exchange rates and trade patterns of Indonesia, Malaysia, the Philippines, Thailand, China, Korea, Singapore, and Taiwan in relation to Japan and the United States, with reference to the Asian currency crises in 1997. In order to analyze these issues, we constructed an international input‐output model linked with macroeconometric models of the ten countries/regions. Analyses on the Asian exchange rates with a currency basket peg framework show that the Asian exchange rate policy was the de‐facto dollar peg policy. As for trade patterns in relation to the yen‐dollar rate; when a country/region's industrial structure is similar to that of Japan's and the yen is weak, the appropriate change of the yen's weight proves to hold its competitiveness. By contrast, the weak yen shows a decrease of its imports, regarding complementary structure. In either case, however, effects are limited.     

DEVELOPING EMPLOYMENT EFFECTS OF INNOVATIONS: MICROECONOMETRIC EVIDENCE FROM TAIWAN

This paper aims to identify the effects of innovation on employment and labor composition in Taiwan. Using a new and detailed firm‐level data set, the empirical results determine that innovations, measured by R&D investments or patent counts, have a positive impact on employment. Both of the estimated employment effects of product and process innovations are overall significantly positive. Although the effects of process innovations differ between high and low R&D‐intensive industries, the process innovation tends to expand the firms’ output and then increase employment for high R&D‐intensive industries. However, it frequently results in laborsavings in terms of production work and reduces jobs in low R&D‐intensive industries. Moreover, technological innovations are found to be non‐neutral, leading to a shift in labor composition in favor of skilled and more educated workers.
