LONG-RUN M3 DEMAND IN SOUTH AFRICA: A COINTEGRATED VAR MODEL

This paper presents a system cointegration analysis of a long‐run demand for money (measured in terms of M3) in South Africa. In particular, the paper estimates a cointegrated vector autoregression model, consisting of real money, income and the opportunity cost of holding money. Using a variety of theory consistent identification schemes, the money demand function is identified along with other two cointegrating relations, namely, an IS‐type relationship and a relationship relating inflation to the spread between long‐ and short‐term interest rates. The model shows that of the variables used, only income and real money are error‐correcting to the money demand relation. The money demand relation is found to be relatively stable over the sample period, when short‐run fluctuations are corrected for. The model further shows that the long‐run link between money and inflation is rather weak.     

Cointegration,error correction,and the demand for money in Mexico

Cointegration, Error Correction and the Demand for Money in Mexico. -Estimates of the long-run demand for narrow and broad definitions of the Mexican money supply over the period 1980Q1–1994Q1 suggest that a single cointegrating relationship exists for real money balances (M1 and M2), a scale variable (real GDP or real consumption expenditure), and the 91-day treasury bill rate. The results from short-run dynamic equations favor M2 as the monetary aggregate to target and suggest that real GDP rather than real private consumption is a more appropriate scale variable in the demand for money function for Mexico.     

U.S. petroleum consumption behavior and oil price uncertainty: Tests of cointegration and parameter instability

This study utilizes cointegration theory to correctly characterize U.S. petroleum consumption behavior. Initial estimates show the absence of any long-run, unique relationship among petroleum consumption, real income, and relative prices. However, the introduction of oil price uncertainty into this relationship shows the presence of a cointegrating relationship. Oil price uncertainty was introduced in two ways, namely, as an exogenous I(1) variable and as a regressand. Estimates of the cointegrating relationship are obtained using a variety of techniques such as the Johansen system, the Phillips-Hansen, the Stock-Watson, the Park canonical cointegrating regression, the Phillips spectral, and the Engle-Granger test procedures. Parameter instability of the cointegrating relationship is tested using methods discussed in Hansen [1992] and Hansen and Johansen [1993]. While previous studies in this literature have yielded mixed results on the issue of cointegration and ignored tests for parameter instability of the cointegrated systems, this study has presented new evidence on an empirically stable petroleum oil demand function.     

Impact of Economic Reforms on Economic Issues: A Study of Ethiopia

Abstract: This paper is an attempt to investigate the impact of economic reforms on the economic issues in Ethiopia. Different economic issues — parameters determining the effectiveness of economic reforms — are separately discussed to measure how far Ethiopia has benefited from the reform policy. A simple and comparative analysis of various economic indicators between the pre‐reform and post‐reform, that is, between 1985/86–1991/92 and 1992/93–2001/02, reveals that those economic reforms have revamped the economy by moving its GDP from its long‐standing poor record to a respectful growing state. Nevertheless, the reforms have failed in attaining other direct economic objectives, such as standard of living, external debt, trade balance deficit and current account deficit. Economic reforms have, no doubt, attracted a significant amount of private investment, but its volume started declining within the reform period and so were privatization proceeds. This study suggests that a full‐fledged and committed reform is indispensable at the earliest to attaining the full benefits of reform policy.     

Productivity change and the effects of policy reform in China's agriculture since 1979

During China's rural reforms, policies were frequently adjusted. Most policies favoured the continuation and deepening of reform; but some were contradictory or even led to regression in the reform process. How have the rural reforms affected China's agricultural production over the past three decades; and what lessons can be learned to aid the future course of reform? To answer these questions, this study estimates productivity change in China's agriculture and evaluates the effects of policy on agricultural output during the reform period. Aggregated provincial‐level data for the 1979–2008 period are used in a translog production frontier model to estimate indices of total factor productivity (TFP) change and its three components—technical change, technical efficiency change, and a scale effect—with a focus on explaining the variation in technical efficiency. The estimation results show that the impressive improvement of TFP change is dominated by the technical change component. However, technical efficiency change and scale effects have worked against the improvement in TFP change in most periods. To improve technical efficiency, social welfare policies designed to eliminate the rural–urban divide, and reform polices focusing on factor market reforms, such as reform of the household registration system (hukou) and reform of land rights, seem to hold some potential.     

Tax and Spend,or Spend and Tax? An Inquiry into the Turkish Budgetary Process

For resolving the budget deficit problem, some economists have advocated spending cuts, while others support either tax increases or tax cuts. This paper investigates the interrelationship between the two fiscal variables for Turkey using bivariate and multivariate cointegrating models. The Engle-Granger and Johansen tests consistently support the existence of one nonzero cointegrating vector representing a stable long-run relationship between government spending and revenues in Turkey. Furthermore, the multivariate error-correction model suggests that taxes unidirectionally Granger-cause negative changes in spending in accordance with the Buchanan-Wagner hypothesis. Thus, from the perspective of policy making and the deficit solution debate, raising taxes in Turkey is perhaps the optimal solution to the current budget deficit predicament.     

Does purchasing power parity survive political shocks in South Africa?

Does Purchasing Power Parity Survive Political Shocks in South Africa? — The objectives of the paper are to examine the Purchasing Power Parity (PPP) hypothesis for the South African economy during the period 1975–1994 using high-frequency data. The analysis is conducted both for the entire period and also for different subperiods in order to take into account possible structural changes. For the rand/ dollar exchange rate, the authors find on the basis of a unique long-run cointegrating relationship that there is significant evidence supporting the PPP hypothesis for the entire period. The use of nonlinear least squares and Johansen-Juselius procedures is made to reach the above conclusion.     

Currency Substitution and the Stability of the Demand for Money in East Asia

Abstract

This paper models and tests the stability of the demand for money in five East Asian countries—Indonesia, Malaysia, Philippines, Singapore, and Thailand—in the context of an open economy. The Johansen multivariate cointegration vector error correction analysis against quarterly data covering the period 1985:1–2001:4 was used. It was found that a stationary long run cointegrating relationship exists between broad money, real income, domestic interest rates, foreign interest rates corrected for exchange rate depreciation, and the expected rate of depreciation of the exchange rate. The results show that US Treasury bills rates and the foreign exchange rate vis-à-vis the US dollar play a significant role in the East Asian countries money demand relationship. This suggests that currency substitution vis-à-vis the US dollar may be an important consideration in the design and implementation of monetary policy in the East Asian countries. Furthermore, the results show that the Asian currency crises impacted the money demand functions negatively in these countries. CUSUM and CUSUMSQ stability tests show no evidence of parameter instability of the money demand functions in three of the five countries throughout the period under investigation.     

Disasters and trade: did Hurricane Katrina affect US imports?

Hurricane Katrina (2005) was the most devastating natural disaster in US history since San Francisco in 1906. A budding literature on disasters and trade suggests that while the impact of natural disasters on small and/or developing countries is significant, the effects on developed countries is not significant. This paper adds to the literature by focusing on a single event for a developed country, the US. In so doing, the aggregation problems of panel studies of many disasters over many countries is avoided. The results suggest that while terrible, Katrina’s effect on US imports was not statistically significant. Estimates of the long-run cointegrating relationship of import demand detected neither the presence of extraordinarily more nor less imports during the period studied (1983:1 to 2008:2). Small, short-run decreases, then increases, can be attributed to the direct effect of a small decline in overall economic activity alone. Recent estimates for income and price elasticities are also obtained and the results compared to other recent shocks, namely, the mild recession of 1990–1991 and the recession and trade collapse in 2008.     

Housing Wealth, Financial Wealth and Consumption in China

The paper investigates the relationship between changes in asset wealth and the trend movements of household consumption in urban China. Using the vector error correction cointegration model we demonstrate that there is a unique long-run cointegrating relationship between household consumption, disposable income, financial wealth and housing wealth in urban China. We find that housing wealth is the only factor that restores the long-run equilibrium relationship when the cointegrated system is disturbed by an external shock. In addition, our permanent-transitory variance decomposition analysis indicates that nearly all variance in the movement of consumption is permanent, supporting the classical random walk hypothesis of consumption behavior. However, a large proportion of variance in the short-run movements of housing wealth is found to be transitory.     

Dynamic forecasting of sticky-price monetary exchange rate model

The Dornbusch-Frankel monetary model is used to estimate the out-of-sample forecasting performance for the U.S. or Canadian dollar exchange rate. By using Johansen's multivariate cointegration, up to three cointegrating vectors were found between the exchange rate and macroeconomic fundamentals. This means that there is a long-run relationship between exchange rate and economic fundamentals. Based on error-correction models, the random-walk model outperforms the Dornbusch-Frankel model at every forecasting horizon. The random-walk model also dominates the Dornbusch-Frankel model with the modified money demand function at every forecasting horizon except one month. However, this paper shows that the share price variable can improve the accuracy of forecasts of exchange rates at short-run horizons.

Business cycle transmission and interdependence between Japan and Australia

This paper investigates business cycle transmission and interdependence between Australia and Japan over the period 1961.1–1994.4. Vector autoregression (VAR) and vector error correction (VEC) models were constructed utilizing GDP/GNPs, producer prices, interest rates and money supplies. The model is tested for cointegration. Two cointegrating vectors are found, and a vector error correction (VEC) model is estimated. The coefficients and the F-tests of the VEC are used to measure the effect of one economy upon the other. Impulse responses from a VAR are examined for evidence of business cycle transmission, and recursive least squares estimates are used to check for structural change in the relationship. Figures are used to graphically demonstrate these relationships and have been collected in an appendix, which can be found at the end of the text.While the two countries engage in a close trading relationship, the two economies are found to be only somewhat interdependent in macroeconometric terms. Japan is found to transmit some of its business cycle fluctuations to Australia, but there is little reverse transmission.     

A Cointegration Model of Age-Specific Fertility and Female Labor Supply in the United States

Cointegration methods suitable for estimation and testing with nonstationary data are applied to U.S. time-series data on age-specific fertility rates, female labor force participation rates, women's wages, unemployment rates and educational attainment, and male relative incomes. Likelihood ratio tests indicate the existence of two cointegrating relations that are identified as a fertility equation and a labor supply equation, respectively. Estimated long-run relations are consistent with economic models of fertility and female labor market behavior, and these results are robust across both age-groups and several alternative model specifications.     

Inflation convergence in the EMS: Some additional evidence. A comment

Conclusions As in Caporale and Pittis, this paper finds significant evidence supporting the hypothesis of long-run equilibrium relationships between inflation rates in countries which participate in the ERM. However, the results differ in several important respects. First, the evidence rejects a dynamic specification in terms of inflation differentials against Germany and in at least one important case, Table 5, it is clear that imposing this restriction may lead to invalid inferences on the role of the ERM as a mechanism to achieve inflation convergence. Second, on the issue of German leadership the results given in Tables 4 and 5 suggest that the German inflation rate cannot be considered weakly exogenous. Rather it shares a long-run relationship with inflation in both ERM and non-ERM economies and responds to deviations from these equilibria. Finally, as these results also hold for a sample period twice the length of that used by Caporale and Pittis they cast considerable doubt on their assertion that cointegrating relationships are unlikely to be detected when “the dynamic process of convergence is still going on”.     

Multi-product firms,product mix changes and upgrading: Evidence from China's state-owned forest areas

Product selection matters for a firm's productivity and long-run growth. Recent theoretical and empirical studies indicate that an important margin of adjustment to policy reforms is the reallocation of output within firms through changes in product mix decisions. This paper examines the frequency, pervasiveness and determinants of product-switching and upgrading activities in firms located in China's state-owned forest areas during a period of gradual institutional and managerial reforms (2004–2008). We find that changes to the product mix are pervasive and characterized by adding or churning products rather than only shedding products. Moreover, changes in firms’ product mix have made a significant contribution to the aggregate output growth during our sample period. We also find that firms with different characteristics, human capital and market conditions differ in their propensity to diversify and upgrade product mix.     

Financial innovation and the long-run demand for money in the United Kingdom and in West-Germany

Financial Innovation and the Long-Run Demand for Money in the United Kingdom and in West Germany. — This paper uses a cointegration model to compare the long-run demand for broad money in the UK and (West) Germany during the period 1963Q1–1990Q2. In the long-run demand function for Germany, real M3 is determined in classical manner by real income and a single opportunity cost variable. By contrast, the UK demand function requires in addition an explicit own rate on money as well as a risk variable. The income elasticity is also very high. These differences reflect the more rapid pace of financial innovation in the UK in the 1970s and 1980s.     

Maximum likelihood cointegration tests of purchasing power parity: Evidence from seventeen OECD countries

Maximum Likelihood Cointegration Tests of Purchasing Power Parity: Evidence from Seventeen OECD Countries. — This paper examines the relevance of long-run purchasing power parity (PPP) during the recent floating exchange rate period, using Johansen’s maximum likelihood method for estimating and testing steady-state relations in multivariate vector autoregressive models. Thirty-two bilateral intercountry relations are considered and it is found that in many cases there exists a long-run relationship between exchange rates and international price differentials, which, however, significantly deviates from PPP in most instances.     

Wage differentials between skilled and unskilled workers

Wage Differentials Between Skilied and Unskilled Workers. — This paper analyzes the change in the ratio of wages paid to skilled and unskilled workers and the effect of these changes on employment by means of a simultaneous-equation pooled time-series cross-section analysis. Hypotheses are derived on the basis of specific theories. The data cover 23 industries over the period 1965–90. The explanatory variables are the cyclical deviations from long-run growth as well as several collective bargaining variables. The wage differential has a strong effect on employment of the two groups under investigation. However, demand has no significant impact on the wage relation.     

Impact of the Global Financial Crisis on China： Empirical Evidence and Policy Implications

This paper applies a structural vector autoregression analysis to quantify the impact of the global financial crisis on China. It is found that the impact is indeed sizeable： a 1-percent decline in economic growth in the USA, the EU and Japan is likely to lead to a0. 73-percent decline in growth in China. The article discusses whether the current measures of fiscal stimulus are adequate to offset the sharp decline in external demand Although there is little doubt that the massive fiscal stimulus will largely offset the significant shortfalls in external demand, the current growth pattern in China will be increasingly unsustainable in the long term. China ＂s reform cycles suggest that external shocks are often opportunities for structural reforms. Therefore, the crisis could also be a catulyst for rebalancing China ＇s economic structure so as to return the economy to a sustainable path.
