Cointegration and Causal Relationship between Taxes and Spending for Kenya,Nigeria and South Africa

Causal relationships between taxes and spending are examined for three African countries using the GDP as a control variable, and dummy variables to address structural changes in Nigeria and South Africa. There is one cointegration equation between nominal fiscal variables in all three countries, one cointegration equation for Kenya and two cointegration equations for Nigeria and South Africa for the real fiscal variables and their respective dummy variables. Short-term results of the nominal variables show fiscal independence for all three countries. In real terms, taxes cause spending for Kenya and Nigeria and a weak fiscal synchronization for South Africa. There is long run fiscal synchronization in nominal terms for all three countries, and in real terms for both Nigeria and South Africa, while real taxes cause spending in Kenya. Long-run estimates show a unit increase in nominal (real) taxes translating into a less than proportionate increase in nominal (real) spending for Kenya and South Africa, and a more than proportionate increase in nominal (real) spending for Nigeria. Fiscal imbalance is not a threat in the budgetary process in Kenya and South Africa, but an issue of concern in Nigeria, where oil revenues are a major source of support for budget short falls.     

中美贸易失衡与人民币汇率“操纵”——基于汇率与贸易收支关系的实证研究

基于2002年1月至2011年12月的月度数据,运用自回归分布滞后(ARDL)模型,分别从总体和分行业的角度,探讨人民币兑美元实际汇率、汇率波动率与中美贸易收支之间的关系。研究结果表明,无论长期还是短期,人民币汇率水平和汇率波动率对中美两国之间总体和分行业贸易收支差额均不会产生显著影响。该结论意味着无论长期还是短期,中国政府都无法通过汇率操纵来达到扩大中美贸易收支顺差的目的。     

Banking sector development and interest rate volatility in emerging economies

Over the last decades, macroeconomic stability is said to be one of the major concerns of emerging economies. Financial sector as a core of macroeconomic stability has been under close consideration of policy makers. The relationship between interest rate uncertainty and banking sector development as one of the most important indicators of financial sector development, especially for emerging economies, has not received enough attention in the literature. Perhaps this article is the most comprehensive study that investigates the relationship between interest rate uncertainty and banking sector development for a large group of emerging economies. To do this, the short-run and long-run models using a bounds testing approach to cointegration for 12 emerging economies over the period 1980–2011 have been developed. Estimated results from all models indicate that interest rate uncertainty has significant effect on banking sector development in both short-run and long-run phenomena in the majority of countries. The findings indicate that the link between interest rate uncertainty and banking sector development in each country depends on each country’s specific structure.     

Is there J-Curve effect in Africa?

The J-Curve is a term used to describe the post-devaluation behavior of the trade balance, i.e., initial deterioration followed by an improvement. Previous research has tested the phenomenon for many developed and developing countries. However, African nations have not received any attention on this regard. In this paper, we test the hypothesis for nine African countries of Burundi, Egypt, Kenya, Mauritius, Morocco, Nigeria, Sierra Leone, South Africa, and Tanzania for which quarterly trade data were available. After using the bounds testing approach to cointegration and error-correction modeling, we were unable to find any support for the J-Curve.     

存贷款利差定价分析

存贷款利差合理水平取决于违约率、损失率、流动性风险、资本缓冲与信贷类资产的比率,以及无风险基准利率。银行业内部管理水平不足和存贷款市场的总体失衡会导致利差水平扩大和提高。我国当前的存贷款利差水平相对于其合理水平而言过低,不仅不利于银行业长期健康发展,而且也对整个金融体系累积了巨大的体系性风险。     

The bilateral J‐curve: Canada versus her 20 trading partners

There is a common belief that currency depreciation worsens the trade balance in the short run and improves it in the long run resulting in the so called J‐curve phenomenon. Early studies employed aggregate data and provided mixed results. Recent studies, however, have employed disaggregated data to remove any aggregation bias from their analysis. In this article we consider the Canadian experience and test the phenomenon between Canada and her 20 major trading partners. Using quarterly data and the bounds testing approach to cointegration, and error‐correction modelling we were able to provide support for the J‐curve in 11 out of 20 cases.     

Monetary dynamics: a market approach

The behaviour of the short-run responses implied by the identification of a long-run money demand relationship is examined. These responses have recently been interpreted as representing the policy stance of the monetary authority. However, as movements in the monetary aggregate reflect both demand and supply adjustments, estimating the short-run dynamics solely within the money demand relationship may produce biased results. In order to address this issue, the paper explicitly acknowledges the importance of the supply of money function by including the function alongside the demand for money function. While the interaction of the two equations continues to produce the long-run quantity theory result, the additional detail provides more accurate estimates of the individual short-run adjustments within the two equations.

本文将利率、贷款抵押成本作为信用成本变量纳入一个分析框架,建立了一个竞争市场条件下综合信贷配给模型,重点研究涉农经济组织在不同信贷市场下的信贷配给.研究表明,涉农经济组织由于信用风险高而被排除在配给范围之外.这个结论可以很好地解释涉农经济组织融资困难这一经济现象.     

论利率市场化下的利率互换功能与风险

随着一系列利率改革措施的颁布实施，我国利率市场化进程正在加速。我国已初步建立市场利率形成机制和市场利率体系。利率市场化催生利率互换，利率互换有利于规避利率风险、降低融资成本、资产负债管理和完善利率定价机制。但是，利率互换存在法律和政策风险、基础协议的效力风险、履约风险以及利率本身的风险。     

Educational attainment,growth and poverty reduction within the MDG framework: simulations and costing for the Peruvian case

Using quarterly data, 1999:Q2–2009:Q3, we empirically examine the key macro determinants of housing prices for China’s residential market. Employing Granger causality and Vector Auto-Regression (VAR) models, we find that there exists strong bivariate causality between house price increases and its determinants. The variance decomposition suggests that speculative factors reflected by past increases in real house price contribute a relatively larger proportion to house price rises relative to fundamental factors.     

Interest rate reforms,financial deepening and economic growth in Tanzania: a dynamic linkage

In this paper we examine the dynamic relationship between interest rate reforms and economic growth in Tanzania using two tests. In the first test, we examine the impact of interest rate reforms on financial deepening using a financial deepening model. In the second test, we examine whether the financial deepening, which results from interest rate reforms, Granger‐causes economic growth – using a trivariate model. The empirical findings of our results reveal that there is a significant positive relationship between interest rate reforms and economic growth in Tanzania. However, the results fail to find any support for finance‐led growth.     

On the impact of financial development on income distribution: time-series evidence

Financial market development is said to have equalizing or unequalizing effects on income distribution. Previous research used cross-sectional and panel data and provided mixed results. Suspecting that they suffer from aggregation bias, we adhere to time-series data and error-correction modeling technique and address the issue one more time in each of the 17 countries for which we have time-series data. In 10 counties, short-run effects of financial market development on income distribution were found to be equalizing. In five countries, the effects were unequalizing. However, the equalizing effects lasted into the long run only in three countries of Denmark, Kenya and Turkey.     

Interest rate reforms,financial deepening and economic growth in Cameroon: an empirical investigation

The impact of interest rate reforms on financial deepening and growth in Cameroon is examined. We employ five proxies of financial deepening against deposit rate, a proxy for interest rate reforms. The impact of interest rate reforms on financial deepening is sensitive to the proxy used for financial deepening. The impact is almost negative and significant for all the indicators, except for the ratio of broad money to Gross Domestic Product, where it is positive and significant in the first lag. This means that financial repression helps improve broad money and hinders the development of the other indicators of financial development in Cameroon.     

人民币实际汇率与中国经济增长的关系研究——基于边限检验法的巴拉萨-萨缪尔森效应检验

以Faria和Leon—Ledesma简化的巴拉萨-萨缪尔森模型为基础,运用Pesaran、Shin和Smith的边限检验法实证分析了1980—2007年期间人民币实际汇率与中国经济增长之间是否存在长期稳定关系。研究发现：改革开放以来,中国经济增长并没有伴随着人民币实际汇率的升值,巴拉萨-萨缪尔森效应在中国不成立。产生这一结果的原因在于：对高估的汇率进行贬值是中国经济高速增长的前奏,非市场化的劳动力市场阻断了BS效应中价格传递机制的发生。但是,如果中国经济保持较高的增长率,人民币实际汇率在长期中将经历一个升值过程。

The government expenditure–economic growth relation in Japan: an analysis by using the ADL test for threshold cointegration

Based on annual data from Japan for the period 1960 to 2010, we investigate the government expenditure–economic growth relation in Japan by using the autoregressive distributed lag test for threshold cointegration developed by Li and Lee (2010). In particular, we evaluate the validity of Wagner’s view and the Keynesian view in the case of Japan. The empirical results presented herein indicate that of these two classical economics perspectives, only Wagner’s view holds for Japan. The findings also demonstrate that the adjustment process towards its long-run equilibrium is asymmetric.     

Financial market development and trade openness: evidence from emerging economies

International trade is said to be the engine of economic growth. Despite an enormous effort to explain this phenomenon, the relationship between financial market development and trade openness and integration into the world economy is still an enigma. This article investigates the relationship between financial market development and trade openness. To do this, we develop a long-run and short-run model (a bounds testing approach to cointegration) for 18 emerging economies over the period 1980 to 2011. Estimates from all models show that financial market development, including both the stock market and the banking sector, has significant effect on trade openness in both short-run and long-run phenomena in the majority of countries. Despite many similarities among emerging economies, additional evidence suggests that the link between either stock market development or banking sector development with trade openness works via each country’s specific structure.     

Does money have a role in the inflation process? Evidence from Australia

Inflation, defined as a sustained increase in the price level, is considered a monetary phenomenon, as it can be explained within the framework of money‐demand and money‐supply relationships. In the extant literature, money growth is shown to remain causally related to inflation across countries and over time, irrespective of the exchange rate regime and stability of the money‐demand function. Nevertheless, emerging literature suggests a diminishing role of money in the conduct of monetary policy for price stability, especially under inflation targeting. Monetary policy in Australia under inflation targeting since 1993 is an example of policy that denies a relationship between money growth and inflation. The proposition that money does not matter insofar as inflation is concerned seems odd in both theory and the best‐practice monetary policy for price stability. This paper uses annual data for the period 1970–2017 and quarterly data for the period 1970Q1–2015Q1. It deploys both the Johansen cointegration approach and the autoregressive distributed lag (ARDL) cointegration approach to investigate for Australia whether money, real output, prices and the exchange rate (non‐stationary variables) maintain the long‐run price‐level relationship that the classical monetary theory suggests in the presence of such stationary variables as the domestic and foreign interest rates. As expected, the empirical findings for Australia are consistent with the classical long‐run price‐level relationship between money, real output, prices and the exchange rate. The error‐correction model of inflation confirms the presence of a cointegral relationship among these variables; it also provides strong evidence of a short‐run causal relationship between money supply growth and inflation. On the basis of a priori theoretical predictions and empirical findings, the paper draws the conclusion that the monetary aggregate and its growth rate matter insofar as inflation is concerned, irrespective of the strategy of monetary policy for price stability.
