Do Capital Controls Enhance Monetary Independence?

International monetary policy trilemma—the tradeoff among exchange rate stability, monetary independence, and unrestricted capital mobility—is an important constraint for policy makers in an open economy. This paper investigates an aspect of the hypothesis that has received relatively less attention: whether a decrease in capital mobility through imposition of capital controls, while holding the degree of exchange rate stability constant, will enhance monetary independence. Using a panel dataset covering 88 countries for the 1995–2010 period and the generalized method of moments (GMM) estimation, we find that: (1) capital controls help improve a country's monetary independence; (2) the effectiveness of capital controls depends on the types of assets and the direction of flows that are imposed; and (3) the choice of exchange rate regime has an important impact on the effectiveness of capital controls on monetary independence.     

The political economy of the impossible trinity

This paper reconsiders the policy trilemma in an open economy by incorporating political economy concerns. We argue that the impact of government ideology on monetary independence, exchange rate stability, and capital flow restrictions should be analyzed in the broader context of restrictions imposed by the impossible trinity instead of the usual single-dimensional constraints. Employing a de facto measurement of these restrictions for a sample of 111 countries from 1980 to 2010, we show that the impact of government ideology on a country's position in this trilemma is highly context dependent: we find that its impact on exchange rate stability and monetary independence varies between developed and developing countries. We also show that the impact of government ideology on these two trilemma components is contingent on the stance of the respective economy's business cycle. Left-leaning governments seem to favor exchange rate stability over monetary independence in case of a negative output gap; suggesting a reversal of their commonly assumed partisan preferences in economically tight times.     

Alternate instruments to manage the capital flow conundrum: A study of selected Asian economies

Capital inflows to and outflows from emerging market economies (EME) have increased significantly since 2000. This rapid increase, accompanied by a sharp rise in volatility, has amplified the complexity of macroeconomic management in EME. While foreign capital provides additional financing for productive investment and offers avenues for risk diversification, unbridled flows exacerbate financial and macroeconomic instability. In this paper, we focus on the experience of six emerging Asian economies (EAE) in dealing with capital flows. Using quarterly data, we identify the waves of capital flows experienced by these EAE and the efficacy of the various policy measures taken. The policy choices include negotiating the trilemma (i.e. balancing the need for monetary policy autonomy, exchange rate flexibility and capital account openness), as per the demands of the macroeconomic situation. The paper also analyses the extent to which intervention in the foreign exchange market and imposition of short‐term capital flow management measures have aided countries to negotiate the trilemma. The efficacy of these responses have been varied across countries, implying that a judicious mix of these measures, along with improvement in financial and institutional development, is required to effectively counter the vagaries of capital flows.     

Capital Controls,Global Liquidity Traps,and the International Policy Trilemma*

The zero bound on interest rates introduces a new dimension to the trilemma in international policy. The openness of the international financial market might render monetary policy ineffective, even within a system of fully flexible exchange rates, because shocks that lead to a liquidity trap in one country are propagated through financial markets to other countries. However, the effectiveness of monetary policy can be restored by the imposition of capital controls. We derive the optimal response of monetary policy to a global liquidity trap in the presence of capital controls. We show that, even though capital controls might facilitate effective monetary policy, capital controls are not generally desirable in terms of welfare.     

Capital control reconsidered: financialisation and economic policy

We consider capital controls and their impact on selected countries, providing a critique of IMF policy. We show how the warning signs of the 1970s were ignored and the consequences became apparent during the ensuing period of neoliberal hegemony. We contend that promoting increased capital mobility is counterproductive as it reduces macroeconomic ‘policy space’. We introduce a development of the international policy ‘trilemma’ in the form of a variant of the idea of the ‘quadrilemma’. We suggest that, in most cases, the key policy driving economic growth is fiscal policy but it may be that its unconstrained use (and that of monetary policy) is not possible either under fixed exchange rates or when free capital mobility exists; a nation may face a ‘demi-quadrilemma’. We contend that, in practice, a country can only adopt ‘two from four’; if it chooses to retain free use of monetary and fiscal policy, it must sacrifice both fixed exchange rates and capital mobility. We advocate the rejection of fixed exchange rates and free capital mobility allowing the retention of requisite monetary and fiscal policy space, and that a multinational approach to the capital control policy would effectively contribute to a growth and development strategy.     

中国的“三元悖论”政策目标组合选择及其影响

本文构建了"三元悖论"政策目标指数,并探讨了中国的宏观经济管理策略对经济稳定性的影响。研究发现,中国以汇率高度稳定作为首要目标,并追求适度的货币政策独立性,而谨慎追求金融开放,并积累了巨额外汇储备。这种策略的影响包括:(1)较高的货币政策独立性对降低产出波动率有积极作用,因持有外汇储备的间接影响使得汇率高度稳定政策也显著降低了产出波动率,金融开放同样也起到了降低产出波动率的作用;(2)积累巨额外汇储备与追求汇率高度稳定政策间的交互影响使得汇率稳定成为维持物价稳定的消极因素,货币政策独立性将降低国内通货膨胀波动率而积累过多的外汇储备却恶化这种影响,金融开放将增加物价波动性。文章凸显出过度追求人民币名义汇率稳定的弊端。     

International Capital Movement and Monetary Independence in Asia

In this paper, we investigate the extent of monetary independence in a group of ten Asian countries: China, Malaysia, Japan, India, Indonesia, Philippines, Thailand, Korea, Singapore, and Hong Kong. While the traditional investigation has considered only the bivariate relationship between the home interest rate and the base rate, we employ both single-equation and vector autoregressive representations of the bivariate and the trivariate relationship including the desired (or optimal) interest rate. We find in most countries, that the ranking of monetary independence is relatively consistent across the models and methodologies although model specifications produce important differences for some countries such as Japan, Indonesia, and India. Trilemma suggests that a country cannot accomplish all three policy objectives: monetary independence, exchange rate stability, and free capital mobility. To increase monetary independence a country must choose between greater exchange rate flexibility or a lower degree of capital mobility. The fact that China and Malaysia, the two countries that are known to have imposed the strictest capital controls, consistently rank high in various scenarios while Hong Kong, which has maintained nearly the freest regime in capital markets, is lowest in monetary independence, indicates that perhaps capital controls may play a more important role than does exchange rate flexibility in securing independence in monetary policy making. On the other hand, countries that maintain greater exchange rate stability do not necessarily rank low, unless it is combined with greater capital mobility as in the case of Hong Kong.     

Financial Trilemma in China and a Comparative Analysis with India

A key challenge facing most emerging market economies today is how to simultaneously maintain monetary independence, exchange rate stability and financial integration subject to the constraints imposed by the trilemma, in an era of widespread globalization. In this paper we review and contrast the trilemma policy choices and trade‐offs faced by the two key drivers of global economic growth: China and India. China's trilemma configurations are unique relative to other emerging markets in terms of the predominance of exchange rate stability, and in the failure of the trilemma regression to capture a consistently significant role for financial integration. In contrast, the trilemma configurations of India are in line with choices made by other emerging countries. Over time, India, like other emerging economies, has converged towards a middle ground among the three policy objectives, and has achieved comparable levels of exchange rate stability and financial integration buffered by sizeable international reserves.     

The international policy trilemma in the post-Bretton Woods era

The international macroeconomic policy trilemma suggests that despite the appeal of exchange rate stability, financial account openness and monetary sovereignty, these cannot be achieved simultaneously. Using elements of Euclidean geometry, this paper proposes a new method for testing the trilemma and finds considerable evidence in support of it. Further tests indicate that, on average, policy configurations are not on the trilemma constraint, i.e. there is a degree of ‘trilemma-ineffectiveness’, which is costly for real output growth and price inflation. It is shown that these costs are associated with limited exchange rate stability and financial account openness.     

汇率-资本流动性的制度安排和财政-货币政策的有效性研究

笔者通过拓广的蒙代尔-弗莱明模型,并突破了传统的"三元冲突"汇率制度安排理论的研究路径,考虑引入资本流动性相对强度系数的概念,又在固定汇率制下引入"冲销"干预政策因素,提出了一个在固定和浮动汇率及不同资本流动性制度安排下财政-货币政策有效性指数曲线的新假说,对汇率-资本流动性制度安排对于宏观经济政策(财政-货币政策)综合有效性的影响问题做了一些较为深入的探讨.笔者认为,我国作为一个经济大国应尽可能地拥有宏观经济政策的自主权,考虑到我国当前金融市场体系尚不够完善,货币政策传导机制还存在严重障碍,所以在近期财政政策的权重应大于货币政策,从而在我国汇率制度改革过程中,为保留宏观经济政策的自主权,在加快放宽人民币汇率弹性的同时必须加强相应的资本管制.     

"三元悖论"理论对我国政策搭配的启示

我国长期以来实行的是独立的货币政策、稳定的汇率制度和严格的资本管制。当前在人民币汇率面临升值压力的情况下,这种政策搭配格局是否还合适、是否应该改善已成为一个热点问题。当前我国合理的政策搭配应该是保证货币政策相对独立性的前提下,汇率波动幅度的逐渐增大和资本管制的逐渐放松相结合的模式。     

Monetary transmission in three central European economies: evidence from time-varying coefficient vector autoregressions

We study the transmission of monetary policy to macroeconomic variables with structural time-varying coefficient vector autoregressions in the Czech Republic, Hungary and Poland, in comparison with that in the euro area. These three countries have experienced changes in monetary policy regimes and went through substantial structural changes, which call for the use of a time-varying parameter analysis. Our results indicate that the impact on output of a monetary shock changed over time. At the point of the last observation of our sample, the fourth quarter of 2011, among the three countries, monetary policy was most powerful in Poland and not much less strong than the transmission in the euro area. We discuss various factors that can contribute to differences in monetary transmission, such as financial structure, labour market rigidities, industry composition, exchange rate regime, credibility of monetary policy and trade openness.     

Cyclical fiscal rules for oil-exporting countries

Budget-balance tax-gap rules are preferred to other fiscal policy rules to stabilize the macroeconomic volatility and welfare in oil-exporting countries. The output-inflation trade-off is of particular concern for oil exporters relative to non-oil commodity exporters due to the pass through of oil prices into headline inflation which warrants fiscal reaction to crude oil revenue. This result is robust to several instruments satisfying the rule but with reduced efficiency for those instruments that impact potential output such as government investment and capital taxes. These rules are desirable for fixed exchange rate regimes but are unable to achieve the same degree of stability as when coordinated with inflation-targeting monetary policy. Even under optimal inflation-targeting regimes, the adoption of budget-balance tax-gap rules can produce reductions in macroeconomic volatility and welfare gains.     

The “Impossible Trinity” Hypothesis in an Era of Global Imbalances: Measurement and Testing

We outline new metrics for measuring the trilemma aspects: exchange rate flexibility, monetary independence, and capital account openness, taking into account substantial international reserve accumulation that has taken place since the 2000s. Since 1990, the trilemma variables in emerging markets have converged towards intermediate levels, characterizing by managed flexibility, using sizable international reserves as a buffer while retaining some degree of monetary autonomy. We test the linearity of the trilemma, and find that the weighted sum of the three trilemma variables adds up to a constant. Thus, a rise in one trilemma variable should be traded‐off with a drop of the weighted sum of the other two.     

The Macroeconomic Management of Increased Aid: Policy Lessons from Recent Experience

The authors investigate the macroeconomic challenges created by a surge in aid inflows. They develop an analytical framework for examining possible policy responses to increased aid, in terms of absorption and spending of aid—where the central bank controls absorption, through monetary policy and the sale of foreign exchange, and where the fiscal authority controls spending. Different combinations of absorption and spending lead to different macroeconomic consequences. Evidence from five countries that recently experienced an aid surge (Ethiopia, Ghana, Tanzania, Mozambique, and Uganda) shows no support for aid-related real exchange rate appreciation in these countries, but it does indicate that the fear of Dutch disease played an important part in the policy reaction to aid surges. Fiscal and monetary authorities should coordinate their responses to an aid surge, because an uncoordinated response—typically when the fiscal authority wants to spend aid while the central bank wants to avoid exchange rate appreciation—can have serious negative macroeconomic consequences.     

Evidence on the sectoral monetary transmission process under a fixed exchange rate regime

Traditional macroeconomic models suggest that monetary policy changes are largely ineffective in fixed exchange rate economies. However, Edwards and Végh (1997) present a model that shows this might not be the case, as a tightening in monetary policy raises financial costs faced by firms and therefore lowers real wages and, by extension, consumption. This paper empirically tests this hypothesis using data on a country with one of the longest running fixed exchange rate regimes (1975–present). The results of the study confirm the theoretical predictions of Edwards and Végh, but they also show that the propagation of nominal shocks in fixed exchange rate systems is comparatively slower than in countries with a more flexible exchange rate regime.     

Capital flows in a transitional economy and the sterilization dilemma: The hungarian experience, 1992–97

This paper evaluates Hungary's dilemma with sterilization in the context of the record of countries elsewhere that have experienced similar capital inflow episodes, e.g., Latin America and Asia. The study focuses on the short-run impact of sterilization on monetary policy. The empirical results indicate that sterilized interventions by the National Bank of Hungary (NBH) did not neutralize capital inflows until possibly the middle of 1995, following a change in government and, more significantly, a change in exchange rate regimes. Indeed, it appears that monetary policy was overly restrictive and that, for a time, the NBH overcompensated for the inflows of capital.     

国际资本流动对中国货币政策影响的实证研究

在开放经济的"三元冲突"中,中国选择了固定汇率,较严格的资本管制和较大的货币政策独立性,即用少量货币政策独立性的丧失换取有限度的资本流动.但在这种组合下,随着我国资本流动规模的扩大,货币政策独立性也将进一步丧失.对于中国,货币政策的自主权至关重要,除非有能力继续维持更严格的资本管制,我国必须逐步扩大汇率的浮动区间.     

Oil shocks and monetary policy rules in emerging economies

We examine the effects of shocks in the oil market on key macroeconomic variables in small open economies using a dynamic stochastic general equilibrium model with sticky prices and imperfect competition under different monetary policy rules. The numerical solutions show that the types of exchange rate regimes and monetary policies could partly explain the trends in macroeconomic volatilities considering negative shocks to oil supply (Hamilton, 1983) and positive shocks to oil demand (Kilian, 2009). These findings are confirmed in vector autoregressive responses for Chile and Israel with inflation targeting under flexible exchange regimes and Hong Kong with fixed regime.     

渐进资本开放下中国货币政策的独立性

对中国资本流动程度和中国货币政策独立性的回归检验结果表明:中国的经济实践是符合不可能三角命题的。在1980—2003年间,在事实上钉住美元的固定汇率制度下,中国实行着较为严格的资本管制政策和享有独立的货币政策,但货币政策主要依赖于数量调控工具,汇率和利率的价格调控微乎其微,货币政策的独立性受到极大的挑战。
