The ‘trilemma’ hypothesis and policy implications for Fiji

This paper examines the trilemma constraint for Fiji; that is, we investigate how trilemma policy variables were used to address policy trade‐offs among the three objectives of exchange rate stability, monetary autonomy, and financial openness. Fiji makes an interesting case because of its policy orientation towards a stable exchange rate and adequate foreign reserves. Our results suggest that the trilemma constraint is binding for Fiji and policy priority is given to exchange rate stability and monetary policy independence, while less emphasis is placed on financial market openness. We also find that the actual policy levels do not deviate substantially from optimal levels, which evidences that Fiji's policy management has been efficient under the trilemma constraint. Finally, we also study the effects of various trilemma policy combinations and foreign reserve holdings on output growth and inflation.     

从“三元悖论”谈我国人民币汇率制度的选择

作为经典的汇率制度选择依据——“三元悖论“，长期以来一直被学术界所信奉，同样在我国，近年来关于人民币汇率制度的选择问题也是一直以此为基石。认为人民币汇率制度的选择主要依据是我国中央银行的货币政策自主。然而本文将利用Mendel-Fleming和Mendel-Fleming-Dombusch两个模型去分析，得出即使在国际资本完全不自由流动下的固定汇率政策以及在国际资本的完全自由流动情况下的浮动汇率政策都无法完全得以实现，从而理清了我国人民币汇率制度选择时依赖于中央银行货币政策自主的模糊认识。

Navigating the trilemma: Capital flows and monetary policy in China

In recent years China has faced an increasing trilemma—how to pursue an independent domestic monetary policy and limit exchange rate flexibility, while at the same time facing large and growing international capital flows. This paper analyzes the impact of the trilemma on China's monetary policy as the country liberalizes its good and financial markets and integrates with the world economy. It shows how China has sought to insulate its reserve money from the effects of balance of payments inflows by sterilizing through the issuance of central bank liabilities. However, we report empirical results indicating that sterilization dropped precipitously in 2006 in the face of the ongoing massive buildup of international reserves, leading to a surge in reserve money growth.We also estimate a vector error correction model linking the surge in China's reserve money to broad money, real GDP, and the price level. We use this model to explore the inflationary implications of different policy scenarios. Under a scenario of continued rapid reserve money growth (consistent with limited sterilization of foreign exchange reserve accumulation) and strong economic growth, the model predicts a rapid increase in inflation. A model simulation using an extension of the framework that incorporates recent increases in bank reserve requirements also implies a rapid rise in inflation. By contrast, model simulations incorporating a sharp slowdown in economic growth such as that seen in late 2008 and 2009 lead to less inflation pressure even with a substantial buildup in international reserves.     

Effectiveness of Capital Controls and Sterilizations in China

Since 2003, China has been facing a trilemma of determining how to maintain independent monetary policy and limit exchange rate flexibility simultaneously, while facing persistent and substantial international capital flows. The present paper is an empirical evaluation of the effectiveness of China＇s sterilizations and capital mobility regulations, measured by sterilization and offset coefficients, respectively, using monthly data between mid-1999 and March 2009. We find that the effectiveness of China＇s sterilizations is almost perfect in terms of the monetary base, but not in terms of M2, and that China＇s capital controls still work but are not quite effective. Recursive estimation reveals that increasing mobility of capital flows and decreasing effectiveness of sterilizations might undercut China＇s ability to maintain monetary autonomy and domestic currency stability simultaneously. To solve the trilemma smoothly, China＇s monetary authority should continue to relax the management of the exchange rate, and take further steps towards deregulation of capital outflows.     

Bank loans and the effects of monetary policy in China: VAR/VECM approach

In this paper, we test the differential effects of monetary policy shock on aspects of banks' balance sheets (deposits, loans, and securities) across bank categories (aggregate banks, state banks, and non-state banks) as well as on macroeconomic variables (output, consumer price index, exports, imports, and foreign exchange reserves). We do so by estimating VAR/VEC Models to uncover the transmission mechanisms of China's monetary policy. Also we identify the cointegrating vectors to establish the long-run relationship between these variables. By using monthly aggregate bank data and disaggregated data on bank and loan types from 1996 to 2006, our study suggests the existence of a bank lending channel, an interest rate channel and an asset price channel. Furthermore, we discuss and explore the distribution and growth effects of China's monetary policy on China's real economy. In addition, we investigate the effects of China's monetary policy on China's international trade. Finally, we identify the cointegrating vectors among these variables and set up VEC Models to uncover the long-run relationships that connect the indicators of monetary policy, bank balance sheet variables and the macroeconomic variables in China.     

Autonomy and Effectiveness of Chinese Monetary Policy under the De Facto Fixed Exchange Rate System

This paper uses monthly data to examine the autonomy and effectiveness of monetary policy in China under the de facto fixed exchange rate arrangement in place from 1998 to 2005. The results obtained from Granger causality tests in a vector autoregression framework indicate that： （i） China actually conducted independent monetary policy during the fixed exchange rate period; and （ii） market-oriented policy measures are impotent in influencing real output and prices. The framework of the investigation into the autonomy of monetary policy adapts to the Chinese economic condition that primary loan and deposit rates are set by the central bank. Based on the empirical results, the present paper provides alternative strategies to improve the effectiveness of monetary policy in China, including developing the financial system and solidifying microeconomic fundamentals instead of forcing the adaptation of a more flexible exchange rate regime.     

On the conduct of monetary policy in Vietnam

Vietnam has the highest inflation rate in Southeast Asia (over 20 per cent year‐on‐year in 2011). This paper examines the extent to which inflation in Vietnam is due to its conduct of monetary policy. It is argued that, had the central bank implemented policy on a more timely basis, inflation would not have been as high as it was, but the more fundamental problem is that the central bank does not have the tools it needs to conduct monetary policy effectively. Monetary policy is further complicated by Vietnam's exchange rate policy. By choosing to peg the currency and maintain fairly free capital mobility, the country has all but given up the ability to pursue an independent monetary policy. As a consequence, the central bank is forced to attempt to sterilise its foreign exchange interventions, which it is ill‐equipped to do. The paper argues that financial sector liberalisation is needed not only to promote growth but also to maintain macroeconomic stability.     

Surfing the waves of globalization: Asia and financial globalization in the context of the trilemma

Using the “trilemma indexes” developed by Aizenman et al. (2010) that measure the extent of achievement in each of the three policy goals in the trilemma—monetary independence, exchange rate stability, and financial openness—we examine how policy configurations affect macroeconomic performances, with focus on the Asian economies. We find that the three policy choices matter for output volatility and the medium-term level of inflation. Greater monetary independence is associated with lower output volatility while greater exchange rate stability implies greater output volatility, which can be mitigated if a country holds international reserves (IR) at a level higher than a threshold (about 20% of GDP). Greater monetary autonomy is associated with a higher level of inflation while greater exchange rate stability and greater financial openness could lower the inflation rate. We find that trilemma policy configurations affect output volatility through the investment or trade channel depending on the openness of the economies. Our results indicate that policy makers in a more open economy would prefer pursuing greater exchange rate stability while holding a massive amount of IR. Asian emerging market economies are found to be equipped with macroeconomic policy configurations that help the economies to dampen the volatility of the real exchange rate. These economies’ sizeable amount of IR holding appears to enhance the stabilizing effect of the trilemma policy choices, and this may help explain the recent phenomenal buildup of IR in the region.     

Policy Choices and Resilience to International Monetary Shocks

Abstract

The well-known trilemma theory states that the nominal exchange rate regime plays a crucial role in a country's ability to pursue monetary policy that is for its domestic objectives independent from other countries' influences. In particular, a flexible exchange rate is required for an independent monetary policy. Capital controls may help a country with a fixed exchange rate to gain some policy space but the effect of capital controls is leaky and often short-lived. We revisit these conventional wisdoms and find no strong evidence supporting them in practice. In particular, a flexible exchange rate does not reliably deliver monetary policy independence, but capital controls do. This is consistent with the view that most (developing) countries dislike either depreciation or appreciation of their currencies, and therefore would choose to follow US monetary policy moves even if they are on a flexible exchange rate regime. In other words, to build resilience to international monetary policy shocks, capital controls are a necessarily component.     

人民币国际化对货币政策有效性的影响

人民币国际化是否影响货币政策有效性?是人民币国际化程度提高之后货币大规模跨境流动而引起的担忧。文章研究发现,在给定其他因素不变的情况下,人民币国际化程度的提高放大了境外汇率变动对国内经济产出和价格的影响。因此,人民币国际化背景下,中央银行应将境外汇率失衡纳入货币政策的反应函数,反应系数取决于境外利率、产出和价格对境外货币需求的决定系数。理论分析还表明,人民币国际化程度不影响货币政策对国内价格的有效性,而是否影响货币政策对国内经济产出的有效性,则取决于经济结构特征。实证结果表明,目前人民币国际化未对国内利率、产出和价格带来明显冲击,且无论是在M0层次,还是在M2层次,人民币国际化均未明显影响国内货币政策有效性。     

The costs and benefits of exchange rate protection in China

From 2002 to 2011, China ran large surpluses in both the current and capital accounts of its balance of payments, which the People's Bank of China (PBOC) purchased and held at official foreign reserves to avoid nominal appreciation of the currency. Concurrently, with its massive purchases of foreign exchange, the PBOC compelled commercial banks to buy PBOC ‘sterilisation bonds’ and raised commercial bank reserve requirement ratios to avoid monetisation of its foreign exchange purchases and concomitant upward pressure on the price level (that is, real appreciation of the currency). Sterilising foreign exchange intervention, as China did for a decade, constitutes a violation of the implicit rules of a fixed exchange rate regime and as such can be seen as a mercantilist policy of manipulating the real exchange rate to gain, or avoid losing, international price competitiveness—what Corden (1981) termed ‘exchange rate protection’. This paper sets out the simple theory of the costs and benefits of exchange rate protection and provides back‐of‐the‐envelope estimates of their magnitude in China in the 2000s. It also explores the ‘other side of the story’, the decline in US manufacturing employment in the 2000s, which recent literature attributes to a ‘China Trade Shock’ that allegedly resulted from the US granting Permanent Normal Trade Relations (PNTR) to China in 2001. Here, it is argued that the so‐called China Trade Shock resulted from China's sterilised intervention policy, not the granting of PNTR. The implications of these competing hypotheses are considered in the conclusions.     

Losing autonomy: the Norwegian central bank during the Second World War

In the mid‐twentieth century a number of central banks around the western world lost their operational autonomy and were placed under government control. The origin of these policy changes can be traced to the intellectual and political developments of the interwar era in addition to the introduction of the Bretton Woods monetary system. The Norwegian central bank offers a particularly stark example of this phenomenon: experiencing a rapid decline from its high level of autonomy in the interwar years, to a clear subordination to the government after 1945. Through an analysis of the correspondence between the main policy makers in the exiled Norwegian government and central bank management, this article contributes to the understanding of central bank autonomy by tracing the decisive factors that led to the Norwegian central bank's loss of agency.     

外汇储备剧增导致的货币政策困境

外汇储备是体现和制约货币政策有效性的重要因素。根据“三元悖论”,中国政府为确保汇率稳定,同时实现资本准自由流动,必定要以牺牲货币政策独立性为代价。外汇储备超常增长、大量外汇占款导致央行货币政策的实施陷入被动和效果趋弱的困境,给宏观调控政策的选择提出更加复杂的难题。基于此现状,本文对该困境形成的原因和不利影响加以分析,尝试寻求解决办法。     

我国央行票据冲销操作的实证研究

随着我国外汇储备的激增,近几年,央行票据已经成为中央银行进行冲销操作、回收基础货币最重要的手段。通过运用VAR模型对央行票据冲销操作进行实证检验,研究表明:央行票据的货币冲销效果在短期内是非中性的,它通过影响基础货币和货币市场利率作用于货币供给量;长期内央行票据冲销操作对货币供给量的影响趋于中性,不具有可持续性。     

Transforming Central Bank Liabilities into Government Debt: The Case of China

Where policy has substantially increased central bank assets, the corresponding liabilities present an opportunity to increase the breadth, depth and liquidity of the government bond market. In China's case, transformed illiquid central bank liabilities could double or triple the stock of government bonds. Central bank liabilities can be transformed into government bonds either through the government's purchase of foreign exchange reserves held by the central bank or by the government overfunding its borrowing requirement and depositing the proceeds in the central bank. The overfunding approach is preferred if, for financial stability reasons, it is judged prudent to leave the central bank with sufficient resources to serve itself as lender of last resort in foreign currency to the banking system. In the case of China, public debt consolidation could also contribute to further liberalizing the Chinese banking system, wider international use of the renminbi and more balanced holdings of key currency government bonds.

中国货币政策的福利损失与政策规则选择——基于新凯恩斯DSGE模型的分析

本文在新凯恩斯主义DSGE模型框架下,运用福利损失函数和脉冲响应方法研究我国最优货币政策规则选择的问题。研究结果表明,货币供应量规则相对于利率规则,使外生冲击对产出和通货膨胀的影响更持久,造成更大的福利损失,因此中央银行的货币政策规则应该逐步从货币供应量规则转向利率规则;在一定条件下,前瞻型利率规则、后顾型利率规则和泰勒规则所造成的福利损失相差不大,从便利的角度出发,中央银行应该选择后顾型利率规则。     

International monetary transmission in East Asia: Floaters,non-floaters,and capital controls

This paper analyzes the impacts of the United States (US) monetary shocks on East Asian countries using structural vector-autoregression (VAR) model. We find that the impacts of the US monetary shocks on East Asian domestic interest rates and exchange rates contradict conventional wisdom. The conventional exchange rate channel is unlikely to play much role in the transmission of the US monetary policy shocks to floaters in East Asian countries, excluding Japan. In these countries, the domestic interest rates respond strongly to the US interest rate changes, by giving up monetary autonomy, probably because of fear of floating. However, the domestic interest rate does not respond much in countries with fixed exchange rate regimes and capital account restrictions, such as China and Malaysia. This may suggest that the countries with fixed exchange rate regimes enjoy a higher degree of monetary autonomy, most likely with the help of capital account restrictions.     

Estimating forward-looking rules for China's Monetary Policy: A regime-switching perspective

This paper introduces a regime-switching forward-looking Taylor rule to describe the monetary policy behavior and considers its estimation using a two-step MLE procedure due to Kim and Nelson (2006), Kim (2009) and Zheng and Wang (2010). By doing an empirical analysis on quarterly data for China over the period 1992–2010, our results show that the actual reactions of China's monetary policy can be well characterized by a two-regime forward-looking Taylor rule. Furthermore, it is also suggested that the interest rate policy in response to inflation and output gap is asymmetric, behaving a significant characteristic of regime-switching nonlinearity. Specifically, in the first regime the People's Bank of China targets inflation, but not focuses on the output gap; while in the second regime the central bank targets the output gap and the policy rule is not a stable framework.
