چکیده انگلیسی

This paper employs the intervention indices measured from the modified Weymark (1997) model and modified trade models to evaluate the role of China's intervention behavior in the trade balances with its four major trade partners. In our constructed trade models, the intervention effects comprise direct and interactive phases, and their overall effects are diverse. Empirical results show that intervention actions actually create the largest trade advantage for China in the China–Japan case followed by the China–US case creating the next largest trade advantage for China. However, the trade balance is worsened in the China-European Unit case and in the China–Taiwan case. Considering the J-curve effect and the negative interactive effect in the China-European Unit case, the rate of the Chinese renminbi against the euro is not an appropriate intervention object for China.

مقدمه انگلیسی

China has played an important role in promoting world economic growth in recent years. According to the Chinese National Bureau of Statistics report, China's GDP leapfrogged over Germany's allowing China to become the world's third-largest economy in 2007, and China has replaced Japan as the world's second-largest economy since the second quarter of 2010. Rapid economic growth has allowed China to accumulate a huge trade surplus and attract a great amount of foreign capital inflow. Regretfully, this enormous balance of payment surplus also brought about the appreciation pressure of Chinese currency, the renminbi (RMB). Until 2005, the RMB had been artificially pegged to the US dollar within a narrow band. However, this policy has recently come under attack. The Chinese government is now forced to appreciate the RMB in order to reduce the US trade deficit. Sun and Ma (2007) employed a sticky-price monetary model to simulate the anticipated appreciation pressure of the RMB. They indicated that market-oriented interest rates can alleviate part of the appreciation pressure automatically. However, if government abandons the intervention in the foreign exchange market, the pegged regime will eventually collapse due to the persistent appreciation pressure. Considering the flexibility of intervention operations, China eventually made a reform from pegging to the US dollar to a basket of major trading partner currencies in July 2005. Many prior studies argued that China's huge trade surplus mainly comes from the undervaluation of the RMB, which is highly correlated with China's heavy intervention in the foreign exchange market. Therefore, researchers attempted to estimate the RMB equilibrium exchange rate and investigate the extent of the RMB deviation from its equilibrium level. Early studies used the purchasing power parity theory to estimate the RMB equilibrium exchange rate (Yang and Dou, 2004 and Yu, 2000). More recently, however, researchers adopted the economic fundamentals approach (Coudert and Couharde, 2007 and Goh and Kim, 2006). Coudert and Couharde (2007) agreed that the RMB was undervalued, especially with respect to the US dollar during the period 2002–2005. In contrast, Wang, Hui, and Abdol (2007) argued that the RMB fluctuates closely around its long run equilibrium level. While many researchers continuously engage in estimating the RMB equilibrium exchange rate, there is still no consistent conclusion about the misalignment of the RMB. Therefore, it is not appropriate to assert that the RMB is intentionally undervalued to benefit China's trade advantages. Whether the misalignment of the RMB is the result of the central bank's intervention in the foreign exchange market and whether the intervention action can benefit China's international trade have not been well investigated in previous studies. To verify these topics, this paper will first measure the intervention degree of the central bank and then evaluate its effect on China's trade balance.1 Unfortunately, due to the consideration of policy effectiveness, only a few countries have made this intervention information public until recently.2 To overcome this problem, researchers attempted to employ an open economy model to measure the exchange market pressure (EMP) and the central bank's intervention action3 (Fischer, 2006, Frenkel et al., 2005, Humpage, 2003, Ito, 2007, Jun, 2008, Neely, 2005, Pontines and Siregar, 2008 and Sarno and Taylor, 2001). Weymark (1997) proposed an open economy model to quantify the intervention degree by employing observable data. From 1997 on, extensive studies applied the Weymark model to measure the degree of intervention and policy effectiveness (Hsiao et al., 2010, Jeisman, 2005 and Wu and Hsiao, 2004). The main advantage of the Weymark model is that it can be applied to all kinds of managed floating exchange rate regimes and can measure multi-intervention activity. Therefore, this paper first modifies the Weymark model to evaluate China's exchange market pressure (EMP) and intervention index, which is valuable for providing insight into the RMB misalignment problem. To analyze the effect of an intervention policy on a country's international trade, we further modify the trade model commonly used in previous studies (Han, 2000, Kumar and Dhawan, 1991, Mckenzine and Brooks, 1997, Nikolas, 2010 and Peree and Steinherr, 1989). Previous studies specified trade flows as the function of income, relative price, exchange rate and exchange rate volatility, and they neglected the role of intervention actions on trade balance. For example, Mckenzie (1999) showed that the impact of exchange rate volatility on trade flows is ambiguous in both theoretical and empirical studies. Feng and Alon (2007) reported that currency depreciation creates a larger impact on a firm's price adjustment than currency appreciation. Voon and Ran (2006) indicated that both the volatility and misalignment of the real exchange rate have a negative impact on Chinese exporters; therefore, the abatement in the RMB misalignment can stimulate export trade. Moreover, Sun and Ma (2007) stated that if there is no government intervention in the foreign exchange market, the appreciation pressure will cause an excess in foreign reserves accumulation and cause the exchange rate regime to become unstable. This implies that monetary authority can promote trade growth by reducing exchange rate volatility, especially in a developing economy. In other words, the central bank's intervention plays an important role in influencing the exchange rate volatility and trade flows. Overall, the purpose of this paper is twofold: first, to measure China's central bank's intervention behavior by employing the Weymark model; second, to re-examine the relationship between trade and exchange rate volatility by considering the impact of intervention activities. These two issues are virtually neglected in previous studies. The remainder of this paper is organized as follows: Section 2 briefly introduces the specification of empirical models, including Weymark's (1997) modified open economy model and modified trade model. Based on Weymark's modified open economy model, we can establish China's EMPs and intervention indices. Moreover, we add the measured intervention index term and the cross terms relating that index to the level and the volatility of the exchange rate into the traditional trade model to form our modified trade models, from which we can investigate the effect of intervention on trade. Section 3 briefly describes the data sources and methodology. We take China's four major trade countries as examples to evaluate China's bilateral intervention indices and their effects on trade balances. Section 4 shows the empirical results. Finally, the paper ends with our conclusions and policy implications.

نتیجه گیری انگلیسی

Monetary authority sometimes employs an intervention policy to influence the change and the volatility of the exchange rate for promoting export expansion and trade balance accumulation. This is particularly obvious in China. Whether China creates a trade advantage by intervening in the exchange rate of the RMB against a specific currency is a complicated problem. To verify the problem, the previous trade models expressed trade balance as a function of relative income as well as the change and the volatility of the real exchange rate. They neglected the proxy variable of the central bank's intervention actions. This paper highlights the role of intervention behavior of the PBOC in influencing China's trade balances, including direct and interactive effects. Our empirical results show that the direct effect can improve China's trade balance with the US and Japan, indicating that part of China's trade advantages come from the PBOC's intervention actions. Engaging in intervention actions is the major reason why China struggles to keep the RMB/USD and the RMB/JPY rates stable. However, for European Union and Taiwan, the direct effect is insignificant. Regarding the interactive effects, their results are divergent. High intervention can increase China's trade balance with Japan through increasing the slope of the change and the volatility of the real exchange rate. However, the slope of the change of the real exchange rate in the China–EU case and the slope of the volatility of the real exchange rate in the China–Taiwan case will decrease. Overall, based on the positive direct and interactive intervention effects, China's intervention behavior will lead to the largest trade advantage in the China–Japan trade. Although the overall intervention effect in the China–US trade is less than the China–Japan case, China can still seize a specific trade advantage via direct intervention. However, constrained to the J-curve effect and the negative interactive effect of intervention action in the China–EU trade, China fails to employ an intervention policy to obtain a trade advantage, especially in the initial period of adopting a depreciation policy. Therefore, if the trade structure remains unchanged, the RMB/JPY rate is the primary reason for China to intervene in the foreign exchange market; the RMB/USD rate is the secondary reason for such intervention. Our empirical results provide three important policy implications. First, China apparently violates the IMF and the WTO relative agreements for bilateral trade with Japan and the US, but not with Taiwan or Europe; therefore, the trade agreements between China and Japan and China and the US are necessary. Reducing the frequency and the extent of intervention actions in the RMB/USD and the RMB/JPY, and changing bilateral trade structures in China–Japan and China–US cases are viable methods for China to mitigate bilateral trade friction with Japan and the US. Second, China's overall trade benefit from intervening in the RMB exchange rates is not as large as expected because there exists a reverse effect in the China–EU and China–Taiwan cases, which partially offsets the positive effect in China–Japan and China–US cases. There exists significant evidence for China to persuade the IMF that the intervention of the PBOC in the foreign exchange market is not just for overall trade balances. Third, although reducing the intervention of the RMB exchange rates will reduce China's trade balances with the US and Japan, it can synchronously improve China's trade balances with the EU countries and Taiwan. Thus, the steady appreciation of the RMB not only can reduce trade friction but can accelerate overseas investments of China's enterprises, which will further increase China's economic growth.
