Long- and short-term interest rates in 19 countries: Tests of cointegration and parameter instability

This paper examines the long-run relationship between short-term and long-term interest rates (both nominal and real) in 19 countries, and explores the possibility that the relationship is statistically stable using Lc, MeanF, and SupF statistics suggested by Hansen [1992]. Empirical results obtained from various cointegration techniques (Johansen, Phillips and Hansen, Stock and Watson, and Park) and quarterly data (1973–1998) show considerable support for the expectations hypothesis in all countries (except the United Kingdom). In a majority of cases, it is also found that a stable relationship exists between the short-term and long-term interest rates.     

The Money-prices Nexus for Malaysia: New Empirical Evidence from the Time-varying Cointegration and Causality Tests

Abstract

The main objective of this study is to empirically re-investigate the money-prices nexus for Malaysia through the Johansen multivariate cointegration and the modified Wald (MWALD) causality techniques. This study covered the monthly dataset from 1971:M1 to 2008:M11. The Johansen cointegration test suggests that the variables under investigation are co-move in the long run. Furthermore, the MWALD causality test shows a bidirectional causal relationship between money supply (M2) and aggregate prices, meaning that both the monetarist's and also the structuralists' views are vindicated in the Malaysian economy. However, the time-varying cointegration and causality tests indicate that the cointegrating and also the causal relationships are not stable over the analysis period. These results suggest that inflation in Malaysia is not purely a monetary phenomenon. Therefore, implementing a tighter monetary policy may not be an effective macro-economic instrument in managing the inflationary behaviour in the Malaysian economy.     

中印石油消费的动态影响因素比较分析

利用中国与印度1970-2009年的实证数据,运用VAR模型,Johansen协整检验和向量误差修正模型等方法,首次对两国的石油价格、经济增长、人口等因素与石油消费的长期关系及短期动态影响进行了比较分析。结果显示:长期中,石油价格与石油消费的弹性关系,印度表现为负,而在中国为正;经济增长对石油消费的影响,中国大于印度;人口对石油消费的影响,印度大于中国。短期中,印度的经济增长和人口对石油消费的影响更显著,石油价格对两国石油消费的影响程度相似。     

我国居民收入与资产价格关系的实证研究

居民收入与资产价格之间到底存在怎样的关系是理论界广泛关注的问题。在中国当前特殊情况下,房地产和股票分别是两大具有代表性的实体资产与虚拟资产。本文基于较大期限跨度的数据,使用Jo-hansen协整检验和Granger因果关系检验方法,对居民收入和资产价格之间的关系进行实证研究。结论表明,居民收入提高不会导致实体资产价格上升,但会对虚拟资产价格产生一定的影响。基于此,现阶段国内要稳步发展房地产市场和股票市场,引导投资者合理投资,在提高居民收入时要注意促使居民扩大消费而不是追加投资。     

The stock market and the ringgit exchange rate: a note

This paper presents and tests an augmented monetary model that includes the effect of stock prices on the bilateral exchange rates. The model is applied to the ringgit/US dollar (RM/US) and ringgit/Japanese yen (RM/JY) exchange rates. The empirical analysis is conducted by the Johansen method of cointegration. Using the data from the recent float that ends with 1996:Q4, the study is motivated, among others, by an interesting preliminary finding that although the augmented monetary model is cointegrated, it is subject to parameter instability and that the parameter time dependency can be attributed at least partly to a particular subset of the variables in the system including stock prices. We find that a restricted VAR model which imposes exogeneity restrictions on I(1) variables, such as stock prices, among others, exhibits both cointegration and parameter stability. In addition, we demonstrate that exchange rate adjusts to clear any disequilibrium in the long-run relationship. The empirical findings tend to suggest that the equity market is significant in affecting the exchange rate and in explaining at least in part the parameter instability evidenced in the cointegrating system. Hence, we conclude that models of equilibrium exchange rate should be extended to include equity markets in addition to bond markets.

Banking Sector Development and Energy Consumption in Nigeria: Exploring the Causal Relationship and its Implications

This study examines the causal relationship between banking sector development and energy consumption in Nigeria over the period 1971–2013 incorporating crude oil price and indicators of economic performance. An autoregressive distributed lag bounds testing approach to cointegration provides evidence of long‐run relationship among the variables. The long‐run and short‐run estimates suggest that a non‐linear inverted U‐shaped relationship exists between banking sector development and energy consumption in Nigeria, indicating that initially, energy consumption increases as the banking sector develops and then declines as the banking sector matures to generate efficiency in energy consumption. In addition, this study explores the direction of causality between the variables using the Toda–Yamamoto Granger causality test procedure. The results suggest that a unidirectional causality runs from crude oil price to banking sector development, from banking sector development to energy consumption and from energy consumption to economic growth. It may therefore be necessary for policy makers in Nigeria to incorporate banking sector development in the energy and sustainable economic policies.     

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.     

Bayesian analysis of a Markov switching temporal cointegration model

This paper introduces a Bayesian approach to a Markov switching cointegration model that allows the cointegration relationships to be switched on and off depending on the regime. Unlike a classical method for nonlinear cointegration model that uses the cointegrating vector based on a linear cointegration model, the proposed Bayesian method allows for estimation of the cointegrating vector within a nonlinear framework conditional on the regime variables through the Gibbs sampling so that it generates more reliable estimation. The Bayes factors are applied to test for Markov switching and model specifications. The purchasing power parity (PPP) relationship between UK and US is investigated using the proposed model for illustration.     

Purchasing Power Parity under Regime Shifts: An Application to Asian Countries*

This paper re‐examines the long‐run purchasing power parity (PPP) relationship for nine Asian countries relative to the USA and Japan during a period containing significant structural breaks. The relevance of considering structural breaks in PPP tests is demonstrated by utilizing the Johansen et al. (2000) procedure that allows for up to two pre‐determined structural breaks. Using conventional tests without considering breaks, one is able to reject the null of no cointegration for only four countries. The Johansen et al. procedure clearly demonstrates the importance of allowing for structural breaks and provides strong support for long‐run PPP for all the countries, regardless of the base country, except in the case of the Philippines vis‐à‐vis Japan. The Hansen–Johansen parameter constancy test indicates stability for all the countries except the Philippines relative to the USA and Malaysia relative to Japan.

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.     

日本的能源风险、技术应用与技术进步机制

分散原油进口的国别结构对于保障一国能源安全具有重要战略意义.本文在“成本驱动型技术进步机制”理论的基础上,提出了短期“成本驱动型技术应用机制”和长期“风险驱动型技术进步机制”假说,并构建了一个包含能源进口的经济增长决定模型.利用日本1988年1月～2010年10月的月度数据,对工业总产值、原油进口的价格与数量以及原油进口地理集中度共4个变量进行了短期和长期Granger因果关系检验.经验性证据表明:日本同时存在着上述两种机制,无论在短期还是在长期内都足以抵消石油价格冲击的负效应,促进经济增长.茈外,日本调整原油进口地理集中度主要是控制原油进口数量的不确定性,而非原油进口价格波动的风险.本研究从一个崭新的视角解释了能源安全与经济效率的关系.     

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.     

人民币实际汇率与中国就业——基于内生劳动力供给模型的实证研究

本文首先在个体跨期最优理论模型中引入内生劳动力供给因素,建立以中国就业为研究对象的理论模型和相应的计量模型,然后运用Johansen协整分析法、Granger因果检验法及VEC模型探讨1985～2007年期间人民币实际汇率对中国就业的影响。结果表明:长期而言,人民币实际汇率贬值将促进中国就业,人民币实际汇率升值则会抑制就业;而世界实际利率与中国就业显著正相关。在短期内,人民币汇率调整对就业影响存在一定的滞后性,甚至会出现与长期关系相反的现象;世界实际利率与中国就业关系与长期相左。根据上述分析结果,本文提出了相关的政策建议。

本文使用索洛模型为基础的变化模型研究我国就业量的影响因素,引入国民生产总值、城市化率、居民消费水平、历年全社会固定资产投资、第三产业增加值为解释变量做实证研究,建立时间序列分析模型,并通过各变量间的JJ协整关系模型与误差修正模型说明各因素对就业的长短期影响,结果表明长期内我国国内生产总值对就业总量有显著地正向拉动作用,城市化率与就业总量有显著地负相关关系,居民消费水平长期内与就业总量成正相关关系,第三产业增加值与就业总量有微弱的负相关关系,短期内我国就业总量受到自身滞后期的正向冲击且需要外力拉动。在此结论基础上本文尝试提出了相关政策建议。     

石油消费与经济增长关系的分析

随着中国经济的迅速崛起,石油消费量不断增加。本文分析了石油消费与经济增长之间的关系,选取1980～2007年的数据并运用协整理论和Granger因果关系检验理论,对中国石油消费与经济增长之间的关系进行了实证分析。结论表明:1953～2004年,中国石油消费量与经济增长之间存在协整关系,石油消费量的增加是经济增长的原因;1978～2004年,中国石油消费量与经济增长之间同样存在协整关系,经济增长与石油消费量之间具有显著的单向因果关系。     

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.     

The monetary exchange rate model in the long run: An empirical investigation

The Monetary Exchange Rate Model in the Long Run: An Empirical Investigation. — This paper uses the Johansen multivariate cointegration method to examine three variants of the monetary approach to the long-run exchange rate model: flexible price, forward-looking and sticky price monetary models. Evidence is provided for four bilateral sterling exchange rates. The sensitivity of the results to the measurement of monetary aggregates is also examined. The cointegration results provide dismal evidence for the flexible price and forward-looking models irrespective of the measurement of money. The findings are more mixed for the sticky price model, particularly when broad money is used.     

The Power of Cointegration Tests Versus Data Frequency and Time Spans

Using Monte Carlo methods, this study illustrates the potential benefits of using high frequency data series to conduct cointegration analysis. The study also provides an account of why the results are different from those reported by Hakkio and Rush (1991). The simulation results show that when the studies are restricted by relatively short time spans of 30 to 50 years, increasing data frequency may yield considerable power gain and less size distortion, especially when the cointegrating residual is not nearly nonstationary, and/or when the models with nonzero lag orders are required for testing cointegration. The study may help clarify some misconceptions and misinterpretations surrounding the role of data frequency and sample size in cointegration analysis.
