亚洲新兴经济体国际资本流动驱动因素研究——基于GMM模型的实证分析

理解资本流入的驱动因素,对于设计一个有效的资本流动管理政策框架至关重要。本文研究了1998年至2018年间45个新兴经济体面临的各类资本流动的驱动因素,重点分析了资本流向亚洲地区的驱动因素与其他地区的共性和异质性。使用广义矩估计方法(GMM)对面板数据集的实证结果表明,对新兴经济体而言,制度质量和国内因素对吸引资本流入具有重要影响;对亚洲地区来说,人均收入增长和贸易开放是吸引资本流入的重要驱动因素,国内外利差水平和实际有效汇率变动对吸引组合投资和其他投资具有显著影响,VIX指数和影子利率对亚洲新兴经济体资本流动规模的影响也具有重要影响。这表明,在设计管理资本流入的政策框架时,全球经济金融合作和政策协调应被考虑在内。     

Elections and Capital Flows

This paper investigates the extent to which elections affect capital flows. I find little evidence of political capital flow cycles in advanced economies. In emerging and developing countries, however, presidential elections significantly lower preelection foreign direct investment (FDI) inflows but have no effect on other types of capital flows. Furthermore, I find evidence that these cycles are not caused by economic crises related to elections or preelection manipulation of policy variables. These results suggest that uncertainty about future government policies, which should have greater impact on more irreversible forms of capital flows like FDI, may be an important factor in generating this cycle.     

Monetary policy and stock prices – Cross-country evidence from cointegrated VAR models

This study applies the Cointegrated Vector-Autoregressive (CVAR) model to analyze the long-run relationships and short-run dynamics between stock markets and monetary policy across five developed and three emerging economies. Our main aim is to check whether monetary policy plays an important role for stock market developments. As an innovation, monetary policy enters the analysis from three angles: in the form of a broad monetary aggregate, short-term interest rates and net capital flows. Based on this framework, we analyze whether central banks are able to influence stock market developments. Our findings suggest different patterns and causalities for emerging and industrial economies with the stock markets of the former economies more frequently related to monetary aggregates and capital flows. A direct long-run impact from short-term interest rates on stock prices is only observed for 3 out of 8 economies.     

Current Accounts and Global Adjustment: The Long and Short of It

Global rebalancing is underway, but still quite a distance from being done. Current account imbalances have been a persistent feature of the global economy for over 100 years, especially during the two eras of globalization—the period 1870 to 1914 and the present. Such imbalances have reflected underlying imbalances between savings and investment as well as the prevailing international monetary regime. One important lesson from the past 150 years is that capital flows play an important role in funding global investment opportunities—a role that would be harmed if policy makers responded to the perceived threat of global imbalances by imposing any sort of cap. During those periods when capital flows have been relatively unhindered, investment opportunities around the world have been financed by capital flows. Such flows have financed the growth of many erstwhile “emerging market” economies, including the U.S. in the early part of this century. And global capital flows are doing much the same for many emerging markets today, even though purchases of reserves by some countries have been offsetting inbound private capital flows in the aggregate. The other main lesson of history is that imbalances do not last forever, and tend to lead to adjustments and reversals. Experience shows that such adjustments are much easier for surplus countries than for deficit countries.

Monetary policy spillovers and the trilemma in the new normal: Periphery country sensitivity to core country conditions

We investigate why and how the financial conditions of developing and emerging market countries (peripheral countries) can be affected by the movements in the center economies – the U.S., Japan, the Eurozone, and China. We apply a two-step approach. First, we estimate the sensitivity of countries' financial variables to the center economies [policy interest rate, stock market prices, and the real effective exchange rates (REER)] while controlling for global and domestic factors. Next, we examine the association of the estimated sensitivity coefficients with the macroeconomic conditions, policies, real and financial linkages with the center economies, and the level of institutional development. In the last two decades, for most financial variables, the strength of the links with the center economies have been the dominant factor while the movements of policy interest rate also appear sensitive to global financial shocks around the emerging market crises of the late 1990s and since the global financial crisis of 2008. While certain macroeconomic and institutional variables are important, the arrangement of open macropolicies such as the exchange rate regime and financial openness are also found to have direct influence on the sensitivity to the center economies. An economy that pursues greater exchange rate stability and financial openness faces a stronger link with the center economies through policy interest rates and real effective exchange rate (REER) movements. We also find that exchange market pressure (EMP) in peripheral economies is sensitive to the movements of the center economies' REER and EMP during and after the global financial crisis. Open macro policy arrangements, especially exchange rate regimes, also have indirect effects on the strength of financial linkages, interacting with other macroeconomic conditions. Thus, trilemma policy arrangements, including exchange rate flexibility, continue to affect the sensitivity of developing countries to policy changes and shocks in the center economies.     

Effect of Capital Flight on Investment: Evidence from Emerging Markets

Much of the discussion on international capital movements is directed toward studying the effects of foreign capital flows, whereas the implications of resident capital outflows (capital flight) from developing countries remain largely unanalyzed. Using a dynamic panel methodology for twenty-two emerging market economies between 1975 and 2000, this paper investigates the effect of capital flight on investment and how this effect changes with financial liberalization policies. The empirical findings indicate that capital flight reduces private investment dramatically but does not have any effect on public investment. However, no statistically significant impact of financial liberalization on the marginal effect of capital flight on investment is found.     

Spillovers of U.S. unconventional monetary policy to emerging markets: The role of capital flows

We employ a structural global VAR model to analyze whether U.S. unconventional monetary policy shocks, identified through changes in the central bank’s balance sheet, have an impact on financial and economic conditions in emerging market economies (EMEs). Moreover, we study whether international capital flows are an important channel of shock transmission. We find that an expansionary policy shock significantly increases portfolio flows from the U.S. to EMEs for almost two quarters, accompanied by a persistent movement in real and financial variables in recipient countries. Moreover, EMEs on average respond to the shock with an easing of their own monetary policy stance. The findings appear to be independent of heterogeneous country characteristics like the underlying exchange rate arrangement, the quality of institutions, or the degree of financial openness.     

Joining the club? Procyclicality of private capital inflows in lower income developing economies

Using a newly developed dataset this paper examines the cyclicality of private capital inflows to low-income developing countries (LIDCs). The empirical analysis shows that capital inflows to LIDCs are procyclical, yet considerably less procyclical than flows to more advanced economies. The analysis also suggests that flows to LIDCs are more persistent than flows to emerging markets (EMs). There is also evidence that changes in risk aversion are a significant correlate of private capital inflows with the expected sign, but LIDCs seem to be less sensitive to changes in global risk aversion than EMs. A host of robustness checks to alternative estimation methods and control variables confirm the baseline results. In terms of policy implications, these findings suggest that private capital inflows are likely to become more procyclical as LIDCs move along the development path, which could render the conduct of countercyclical monetary and fiscal policies more challenging in these economies.     

Business cycles in emerging economies: the role of interest rates

We find that in a sample of emerging economies business cycles are more volatile than in developed ones, real interest rates are countercyclical and lead the cycle, consumption is more volatile than output and net exports are strongly countercyclical. We present a model of a small open economy, where the real interest rate is decomposed in an international rate and a country risk component. Country risk is affected by fundamental shocks but, through the presence of working capital, also amplifies the effects of those shocks. The model generates business cycles consistent with Argentine data. Eliminating country risk lowers Argentine output volatility by 27% while stabilizing international rates lowers it by less than 3%.     

美联储政策变化、国际资本流动与宏观经济波动

本文构建包含国际投资者、外资企业和银行流动性冲击的DSGE模型来探究美联储货币政策变动和政策不确定性对我国宏观经济的影响和作用机制。研究发现:(1) 美联储加息会导致我国产出、投资和通货膨胀的下降、汇率贬值、国际资本外流和银行系统流动性紧张。随着金融摩擦程度的增加和银行杠杆率的上升,美联储加息对我国产出、投资和资产价格的负面影响会进一步增强。(2) 美联储货币政策不确定性的增加会直接导致外资企业的投资、劳动需求和产出的下降,并对我国总产出、总投资和资产价格产生明显的负向外溢效应,进一步加剧我国宏观经济的波动。(3)为应对美联储的利率变动,适当限制国际资本流动能有效稳定我国经济波动和改善社会福利,而实施固定汇率和央行盯住美国利率的政策会加大宏观经济的波动,并导致社会福利下降。     

Following the leader? The relevance of the Fed funds rate for inflation targeting countries

In a New-Keynesian model for a small open economy, we derive a CPI inflation-based Taylor rule that implements the flexible price allocation. We conclude that, in this rule, the natural rate of interest should be linked to the foreign interest rate and to domestic productivity shocks. This rule ensures that the CPI real rate moves in order to induce movements in consumption that are coherent with the flexible price allocation. The empirical evidence shows that inflation-targeting central banks respond to movements in the Fed funds rate, besides reacting to expected CPI inflation and to the domestic output gap. This is true for developed and emerging economies. Furthermore, we find that in emerging countries the response to foreign variables is not different from zero, as suggested by theory, when domestic inflation, rather than CPI inflation, is introduced in the policy rule.     

量化宽松对世界新兴经济体影响及中国对策

在对主要发达国家实行的量化宽松货币政策措施基础上,通过分析量化宽松货币政策传导机制,得出量化宽松政策将会降低新兴经济体债券收益率、促使新兴经济体货币升值、加大新兴经济体流动性过剩压力、加大新兴经济体通货膨胀压力等结论,认为这些不利影响必然会影响到中国经济稳定。因此,我国应提高人民币存贷款利率、完善人民币汇率形成机制、加强对国际资本流动的监管、调整存款准备金率,以应对中国可能面临的危机。     

Measuring and explaining the volatility of capital flows to emerging countries

This paper analyzes the determinants of the volatility of the various types of capital inflows into emerging countries. After calculating a proxy of the volatility of FDI, portfolio and bank inflows, we use a panel data model to study their relationship with a broad set of explanatory variables. Our results highlight the difficulties policy-makers face in stabilizing capital flows. Thus, we show that since 2000 global factors beyond the control of emerging economies have become increasingly significant relative to country-specific drivers. However, we identify some domestic macroeconomic and financial factors that appear to reduce the volatility of certain capital flows without increasing that of others.     

A SIMPLER CONSUMPTION-BASED ALTERNATIVE TO THE INCOME TAX FOR SOCIALIST ECONOMIES IN TRANSITION

The tax systems of socialist economies in transition will distortresource allocation, create inequities, and cause administrativeheadaches if not reformed. These countries have weak tax administrations,lack experience with mass taxes based on voluntary compliance,and need to encourage domestic saving and foreign investment.This article suggests an alternative to the conventional incometax that is more suited to these conditions. Attempting to tax real economic income raises complicated timingissues (when to recognize income and allow deductions) and mayrequire complex adjustments for inflation. The simplified alternativetax (SAT) avoids these complications and provides a generalincentive for saving and investment less subject to abuse ordistortions than tax holidays and other tax gimmicks in voguein countries emerging from socialism. The key elements of the SAT are separate taxes on income fromlabor and capital, immediate deduction for all business expenditures,no deduction for interest, and no taxation of interest or dividends.(Interest could be treated as under an income tax, at some cost.)Although the marginal effective tax rate is zero, the governmentshares in extraordinary returns to investment. The article discussespotential problems (including distributional implications, taxlosses, and foreign tax credits) as well as advantages of theSAT.

The risk adjusted uncovered equity parity

This paper explores the risk adjusted uncovered equity parity model to investigate a degree of market integration for four Asian emerging markets relative to the U.S., Japan and the U.K. from January 1994 to July 2008. The uncovered equity parity is revised to take into account of market risk in a framework of a portfolio rebalancing model. Evidence was found to strongly support our hypotheses; Market risk is significant in international capital flows between the Asian emerging markets and the developed economies, and it can help explain the failure of a traditional uncovered equity (or interest) parity model. The relationship between returns and an appreciation of the exchange rate are divided between the Asian emerging markets and the developed economies, depending on the direction of capital flows.     

内外部金融周期差异如何影响中国跨境资本流动?

本文揭示了内外部金融周期差异影响跨境资本流动的机制,并以美国为外部经济代表,基于1998年第一季度至2018年第一季度数据进行了实证检验。研究发现:(1)中国跨境资本流动波动主要来自短期资本流动波动;分类看,其他投资波动较大;方向上看,流入波动要大于流出波动。(2)利差、汇差、资产价差(股指变动差异和房价变动差异)是影响跨境资本流动的重要因素,汇差和资产价差对短期资本流动影响尤甚。(3)内外部金融周期差异变动对资本流入的影响比对资本流出的影响更明显。(4)近年来,利差对跨境资本流动影响减弱,汇差和资产价差对跨境资本流动影响增强。结果说明,防范跨境资本流动风险要关注其他投资资本流动大幅波动风险,同时注意防范汇率和资产价格波动共振对跨境资本流动的冲击。     

Capital flows to emerging market economies: A brave new world?

We examine the determinants of net private capital inflows to emerging market economies (EMEs) since 2002. Our main findings are: First, growth and interest rate differentials between EMEs and advanced economies and global risk appetite are statistically and economically important determinants of net private capital inflows. Second, there have been significant changes in the behavior of net inflows from the period before the recent global financial crisis to the post-crisis period, especially for portfolio inflows, partly explained by the greater sensitivity of such flows to interest rate differentials since the crisis. Third, capital controls introduced in recent years do appear to have discouraged both total and portfolio net inflows. Finally, we find positive effects of unconventional U.S. monetary policy on EME inflows, especially portfolio inflows. Even so, U.S. unconventional policy is one among several important factors influencing flows.     

An Information-Based Model of Foreign Direct Investment: The Gains from Trade Revisited

Foreign direct investment (FDI) is observed to be a predominant form of capital flows to emerging economies, especially when they are liquidity-constrained internationally during a global financial crisis. The financial aspects of FDI are the focus of this paper. We analyze the problem of channelling domestic savings into productive investment in the presence of asymmetric information between the managing owners of firms and other portfolio stakeholders. We explore the role played by FDI in reviving equity-financed capital investment for economies plagued by such information problems. In the presence of information asymmetry, the paper identifies, however, how FDI gives rise to foreign overinvestment as well as domestic undersaving. The gains from trade argument (applied to intertemporal trade) is re-examined in this case of informational-asymmetry-driven FDI. We show that the gains could be sizable when the domestic credit market is either under-developed or failing as a result of a financial crisis. But with a well-functioning domestic credit market, the gains turn into losses. Surprisingly, capital may flow into the country even when the autarkic marginal productivity of capital in the domestic economy falls short of the world rate of interest. In such a situation, capital should have efficiently flown out rather than in, and FDI is a social loss-generating phenomenon.
