An Analysis of the Structure of Interest Rates in Taiwan: An Application of the Vector ARIMA Model

The structure of interest rates in Taiwan is analysed through the vector ARIMA approach using monthly and quarterly data from 1978 to 1989. These rates are the regulated bank interest rate and unregulated money market interest rates in the formal financial market and the kerb rate in the informal market. The results show that the adjustments in the bank interest rate follow that of the money market interest rate. Furthermore, the time lag has been shortened from one quarter in the early stages of interest rate liberalization in Taiwan to only one month in the later stages. Increases in the money market interest rate might be followed by an increase in the kerb market interest rate because of partial market segmentation. In periods when there is excess supply of funds in the banking sector, an increase in the bank rate might be followed by a decrease of the kerb rate. The interest rates structure of Taiwan is relevant to developing countries which have an informal financial sector.     

Dynamics of Money Market Interest Rates in Ghana: Time-Frequency Analysis of Volatility Spillovers

As the second longest practicing inflation targeting economy in Africa, it is of interest to investigate the degree to which policy interest rate influences other money market rates so as to gauge the overall effectiveness of monetary policy transmission in Ghana. This study evaluates the degree of connectedness among money market rates and also determines the most dominant money market rate(s) in Ghana. The basic finding is that the monetary policy rate has a low-to-moderate influence on volatility dynamics of other money market rates in Ghana across historical time-interval and time-frequency domains. This is a reflection of a generally weak capability of policy interest rate to drive other market rates in Ghana. Both monetary policy rate and Treasury bill rate are net transmitters of shocks, while interbank, lending and saving rates are net receivers of shocks in the money market. However, the Treasury bill emerges as the largest shock transmitter in the money market, across all forecast horizons and analytical domains. The lending rate is the largest shock recipient in the money market, largely from the Treasury bill rate which suggests ample evidence of fiscal dominance in Ghana. The study accentuates the exigency for monetary and fiscal policies to expeditiously address the domestic structural bottlenecks, especially in the financial sector and the fragile fiscal profile, in order to strengthen policy transmission in Ghana.     

Volatility transmission along the money market yield curve

Volatility Transmission along the Money Market Yield Curve. - The authors model the volatility of money market interest rates — and the transmission of volatility - along the money market yield curve in the UK, Germany, France and Spain. They find a significant volatility transmission from overnight to longer-term money market rates in France, Spain and the U.K. They also find that the countries with lower (higher) reserve requirements tend to have higher (lower) interbank interest rate volatility. However, reserve requirements generate a perverse seasonal effect at the end of the maintenance period.     

Saving,investment, growth and the cost of financial repression

This paper presents a quantitative estimate of the cost of financial repression in developing countries. Here, financial repression is interpreted as the technique of holding institutional interest rates (particularly deposit rates of interest) below their market equilibrium levels. For a sample of developing countries, saving is found to be affected positively by the real deposit rate of interest, as is real money demand, where money is defined broadly to include savings and time deposits. Under disequilibrium interest rate conditions, higher saving which raises real money demand increases pari passu the real supply of credit. Credit availability is an important determinant not only of new investment but also of capacity utilization of the entire capital stock. Hence, the growth rate is itself affected positively by the real deposit rate of interest through two channels – first, the volume of saving and investment and, second, capacity utilization of the entire capital stock, i.e. the measured incremental capital/output ratio. Estimates of saving and growth functions lead to the conclusion that the cost of financial repression appears to be around half a percetage point in economic growth foregone for every one percentage point by which the real deposit rate of interest is set below its market equilibrium rate.

Real financial market exchange rate volatility and portfolio flows

This paper studies the relationship between real financial market exchange rate volatility and US cross-border equity flows. We found strong evidence that causality goes from real financial market exchange rate volatility to equity flows. According to our results, real financial market exchange rate volatility negatively influences purchases of foreign equity. This finding is in line with the portfolio optimization theory. The impact of real financial market exchange rate volatility on sales of foreign equity is also negative. This result can be explained by the theory of behavioral finance which states that investors are reluctant to realize losses of their portfolios. This is why investors decrease sales of assets when riskiness of the assets increases. The impact of real financial market exchange rate on net purchases of foreign equity is positive. It follows from these results that sales of foreign equity decrease more strongly than purchases of foreign equity when riskiness of foreign assets increases.

Hot Money and Business Cycle Volatility： Evidence from China

This paper investigates the link between hot money and business cycle volatility in China from January 1997 to December 2009. Using the structural vector error correction model we find a considerable degree of long-run cointegration and bidirectional causality effects between hot money and business cycle volatility. The speculative shocks are found to temporarily promote China＇s economic growth, but also to exacerbate business cycle volatility. The liquidity shock stemming from hot money is shown to be the primary factor responsible for the significantly enhanced fluctuation in business cycles during the most recent global financial crisis period This could be detrimental to the smooth operation of financial markets. Therefore, informing future policies, it is critical for policy-makers to take precautions against the speculative factors.

MACROECONOMIC UNCERTAINTY AND CONDITIONAL STOCK MARKET VOLATILITY IN SOUTH AFRICA*

This paper analyses how systematic risk emanating from the macroeconomy is transmitted into stock market volatility using augmented autoregressive Generalised Autoregressive Conditional Heteroscedastic (AR‐GARCH) and vector autoregression (VAR) models. Also examined is whether the relationship between the two is bidirectional. By imposing dummies for the 1997‐1998 Asian and the 2007‐2009 sub‐prime financial crises, the study further analyses whether financial crises affect the relationship between macroeconomic uncertainty and stock market volatility. The findings show that macroeconomic uncertainty significantly influences stock market volatility. Although volatilities in inflation, the gold price and the oil price seem to play a role, it is found that volatility in short‐term interest rates and exchange rates are the most important, suggesting that South African domestic financial markets are increasingly becoming interdependent. Finally, the results show that financial crises increase volatility in the stock market and in most macroeconomic variables, and, by so doing, strengthen the effects of changes in macroeconomic variables on the stock market.     

The liquidity trap: Japan, 1996–2001 versus the United States, 1933–1940

Keynes’ “liquidity trap” rarely occurs. But when it does, it has a tremendously adverse effect on the economy concerned. Such was the case of the United States in the 1930s and now that of contemporary Japan. In a liquidity trap, monetary policy pushes the money interest rate to the zero level while expanding the money supply (M1) at a faster rate than nominal GDP. Conventional theory explains this phenomenon as the result of money demand that becomes infinitely interest-elastic at the zero rate, rendering ineffective the rapidly expanding money supply established by the monetary authorities.In this paper, we show that the liquidity trap is a multifaceted phenomenon not limited to the money market. It involves the bank loan market, the bank deposit market, and the bond market interacting together. Of these, the most important is the bank loan market and the least important is the bank deposit market, whose deposit supply becomes horizontal at the zero rate. They are met by relatively interest-inelastic bank loan demand and bank deposit demand. Hence, the causality is completely reversed from the conventional understanding.We give empirical evidence in support of our theory based on data from the United States, 1933–1940 and Japan, 1996–2001. Far apart in time and space, the two cases are remarkably alike and, hence, provide strong supporting evidence.     

Financial market integration,exchange rate policy,and the dynamics of business and employment in Korea

We study the consequences of different degrees of international financial market integration and exchange rate policies in a calibrated, medium-scale model of the Korean economy. The model features endogenous producer entry into domestic and export markets and search-and-matching frictions in labor markets. This allows us to highlight the consequences of financial integration and the exchange rate regime for the dynamics of business creation and unemployment. We show that, under flexible exchange rates, access to international financial markets increases the volatility of both business creation and the number of exporting plants, but the effects on employment volatility are more modest. Pegging the exchange rate can have unfavorable consequences for the effects of terms of trade appreciation, but more financial integration is beneficial under a peg if the economy is subject to both productivity and terms of trade shocks. The combination of a floating exchange rate and internationally complete markets would be the best scenario for Korea among those we focus on.     

Financial Market Volatility and International Reserve Holding Behaviour: A Case Study for Korea,Indonesia, the Philippines,and Thailand

Abstract

The effects of financial market volatility on the international reserve holding behaviour of four Asian countries that experienced the financial crisis in 1997—Korea, Indonesia, the Philippines, and Thailand are investigated. The financial market volatility is modelled and the effect on reserve dynamics, reserve accumulation, and reserve volatility is estimated. Estimations are taken for two periods—pre- and post-crisis—and the structural break test is performed to examine the change in the effects on reserve holding behaviour. The empirical results, in general, support the evidence for the structural change in the effects on reserve holding behaviour after the crisis. This would be one of the evidences of the precautionary motive for reserve holdings after the crisis.     

国际油价波动与石油冲击——基于符号约束VAR模型实证分析

本文利用符号约束识别VAR模型,区分国际石油市场中基本面冲击与非基本面冲击,并考察他们对石油价格影响的相对重要性。我们发现,虽然供需基本面冲击解释了石油价格的大部分波动,但非基本面(投机)冲击对国际石油现货价格仍具有不可忽视的影响。尤其在2007～2008年间,投机冲击一定程度上扭曲了石油市场的价格形成机制,导致油价显著偏离供需基本面决定的价格水平。     

资产价格波动差异:由股市与房价观察

我国股票市场和住宅市场的市盈率与货币幻觉代理变量通货膨胀率、名义利率呈现明显的反向关系,即在高通胀时,市场被低估;在低通胀时,市场被高估。通货膨胀通过货币幻觉,影响资产估值高低。股市的市盈率波动幅度远大于住宅市场,股票价格波动主要来自估值倍数变化;而住宅的估值倍数波动小,房价波动更多地受到了估值倍数与租金变化的综合影响。

Macroeconomic Volatility, Trade and Financial Liberalization in Africa

This paper examines the effects of financial and trade liberalization on growth volatility of real output and consumption in Africa. Our results suggest trade liberalization is associated with greater output and consumption growth volatility while financial liberalization increases the efficacy of consumption smoothing and stabilizes income and consumption growth. In addition, we find financial market depth and institutional quality operate jointly with trade and financial openness to reduce volatility in output and consumption growth. There is also evidence that good institutions which foster low inflation levels and volatility promote consumption and output growth stability.     

Global commodity prices and global stock market volatility shocks: Effects across countries

We investigate the time-varying dynamics of global stock market volatility, commodity prices, domestic output and consumer prices. We find (i) stock market volatility and commodity price shocks impact each other and the economy in a gradual and endogenous adjustment process, (ii) impact of commodity price shock on global stock market volatility is significant during global financial crises, (iii) effects of global stock market volatility on the US output are amplified by endogenous commodity price responses, (iv) effects of global stock market volatility shocks on the economy are heterogeneous across nations and relatively larger in twelve developed countries, (v) four developing/small economies are more vulnerable to commodity price shocks.     

物价变动对会计核算和财务管理的影响

在商品经济尤其是市场经济条件下,物价会因为劳动生产率的变化、货币价值本身的变动、商品的市场供求关系的变化、垄断和竞争的作用等诸多因素的影响而发生变动。物价变动会对原始成本会计理论及会计实务产生一定的影响,而且物价变动尤其是价格的持续上涨也就是通货膨胀的发生,对企业财务活动的影响更为严重,分析物价变动对会计核算和财务管理的影响并且采取措施减轻和消除影响有着极其重要的现实意义。     

Business connectedness or market risk? Evidence from financial institutions in China

We utilize the spectral representation of generalized forecast error variance decomposition to investigate the frequency dynamics of volatility connectedness and systemic risk of financial institutions in China from 2011 to 2018. We find that, first, high-frequency components account for the largest part of volatility connectedness (48.33%), followed by low-frequency components, and finally the medium-frequency components. Second, the low-frequency components reflect the business connectedness among financial institutions, while the high-frequency components capture the market risk. Third, the business connectedness among financial institutions will lead to a rise in overall connectedness as well as the accumulation of potential risks. Further, once a crisis breaks out, the potential risks have realized and the business connectedness among institutions declines; while market risk increases rapidly, which helps systemic financial risk stay at a high level. Lastly, among the financial sectors, the banking sector possesses a relatively higher level of business connectedness which plays an important role in the accumulation of potential financial risks; the securities sector features with higher market risk; while the insurance sector has both comparatively lower business connectedness and market risk.
