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.     

Liquidity shocks: A new solution to the forward premium puzzle

The frequent empirical failure of uncovered interest rate parity raises a question that has not been definitively answered: why do predictable excess returns on currencies persist in competitive currency markets? Supported by data from nine major currencies for 1978:08–2019:09, I provide a novel resolution to this enduring forward premium puzzle by building on the financial economics literature that explores the economic implications of limited access to capital markets. A liquidity shock, or the urgent demand for liquidity by credit-constrained arbitragers liquidating bond holdings, causes losses from sudden drops in bond prices. Arbitragers require a liquidity premium to compensate for potential losses that vary directly with the interest rate. It is this liquidity premium that explains persistent excess returns on currencies. I argue for policies favoring a low interest rate environment and macroprudential controls that ease liquidity constraints to increase the efficiency of international capital markets by reducing the liquidity premium.     

How the Machinery of International Finance Runs with Sand in its Wheels

The dramatic swings in international capital movements in recent years have renewed interest in restrictions on capital flows. This paper provides a model of international asset flows and domestic equity price formation incorporating three restrictions on capital flows. A transaction tax introduces significant asymmetries in the reaction of asset prices to financial and real shocks but has no long-lived effects. Policies targeted to the level of net foreign debt by imposing a tax or outright controls do influence the steady-state levels of the real exchange rate and relative equity prices.     

Capital Controls,Public Debt and Currency Crises

This paper examines the possibility that, contrary to conventional wisdom, capital controls accelerate currency crises. Theoretical analysis shows that capital controls can constitute an additional burden on government budget and so bring forward the onset of crises. Since perfect capital mobility does not occur, domestic interest rates may deviate from world interest rates. High interest rates under capital controls create an additional cost of servicing outstanding domestic public debt, precipitating crises. Even though the government can delay crises with capital controls, welfare may be less than in a situation with perfect capital mobility.     

Does institutional quality resolve the Lucas Paradox?

The Lucas Paradox observes that capital flows predominantly to relatively rich countries, contradicting the neoclassical prediction that it should flow to poorer capital-scarce countries. In an influential study, Alfaro, Kalemli-Ozcan, and Volosovych (AKV) argue that cross-country variation in institutional quality can fully explain the Paradox, contending that if institutional quality is included in regression models explaining international capital inflows, a country’s level of economic development is no longer statistically significant. We replicate AKV’s results using their cross-sectional IFS capital flow data. Motivated by the importance of conducting inference in statistically adequate models, we focus on misspecification testing of alternative functional forms of their empirical model of capital flows. We show that their resolution of the Paradox relies on inference in a misspecified model. In models that do not fail basic misspecification tests, even though institutional quality is a significant determinant of capital inflows, a country’s level of economic development also remains a significant predictor. The same conclusions are reached using an extended dataset covering more recent IFS international capital flow data, first-differenced capital stock data and additional controls.     

我国国际资本流动性程度和非流动性原因的度量与检验--来自中美日三国消费模式对比的经验证据

加入WTO以后,我国的国际资本流动性开始有所加强,流动方式也有所改变。文章选择中国、美国和日本的消费和收入数据,在国家之间实际利率均衡的假设下,通过国家消费模式的考察和对比,发现我国的经济运行并不满足国际资本完全流动性假说,其原因既出于我国资本市场与国际资本市场之间存在进入限制,也出于我国资本市场与国际资本市场的非完全整合。这些经验发现表明,我国经济中的名义利率、汇率和资本市场仍然处于有限管制过程中,必须通过深化国内金融体制改革和逐步实现资本市场开放等有力措施来增强我国国际资本的流动性,进而保持我国快速经济增长和提高整体资源配置效率。     

OPTIMAL FOREIGN BORROWING REVISITED

Foreign capital has become increasingly important in financing investment and growth in developing countries. Foreign capital flows, however, can be volatile as is evident from the recent financial crises. It has also recently been noted by researchers that there is little systematic empirical evidence that foreign capital contributes to the economic growth of developing countries. In this context, this paper attempts to theoretically reevaluate the borrowing behaviour of a developing economy that relies on foreign borrowing for its capital formation. In particular, this paper investigates the implications of different lending policies of international financial institutions. It is found that no matter whether the borrowing interest rate increases with the level of foreign debt per capita or with the foreign‐capital/total‐capital ratio, the economy always moves toward the stationary state. The result holds even when the representative agent regards the interest rate given as constant. This implies that foreign borrowing does help economic growth, irrespective of lending policies of international financial institutions.     

International Transmission of the People's Bank of China's Balance Sheet Expansion

The People's Bank of China's (PBoC) balance sheet expanded more dramatically than any of its major international counterparts during the past decade. The main contribution to this expansion was the rapid accumulation of the central bank's foreign assets, as a result of foreign exchange market intervention. In this paper, we examine the possible international transmission of this expansion by analyzing monthly data for China and 15 other countries over the period 2000–2012. Impulse response analysis based on vector autoregression modeling suggests that the PBoC's balance sheet expansion has greater impacts on developing than on developed countries. So far the influences appear to be dominated by “trade channels” instead of “financial channels,” possibly due to China's capital account controls. However, the impacts of the PBoC's balance sheet expansion on other countries' interest rates, exchange rates, and stock market prices could strengthen significantly in the coming years as China's economic scale grows and its capital account opens up.     

Currency Regime and Monetary Autonomy. Empirical Evidence Using Recent and Global Data from 1990 to 2007

This paper analyzes the exchange rate regimes from the perspective of monetary independence. To be specific, using recent and global data, we examine the sensitivity of domestic interest rates to the international interest rate, by conducting co-integration tests and by estimating the adjustment speeds through error-correction model, for different de facto currency regimes and for different types of capital markets. Our estimation results basically support the traditional views of ‘impossible trinity’, as far as the cases with open capital markets are concerned. The floating regime shows the less sensitivity of domestic interest rates to the international interest rate than the fixed regime does, which implies some capacity for domestic monetary autonomy under the floating regime. The cases with closed capital markets, on the other hand, include the cases showing high sensitivity of interest rates in some emerging market economies, which might imply the ‘fear of floating’ hypothesis.     

The non-linear impact of monetary policy on international reserves: macroeconomic variables nexus

This paper employs panel smooth transition regression models to investigate the nonlinear effects of two monetary policy proxies (i.e., real exchange rate return and real interest rate differential) on the international reserves—macroeconomic variables nexus. The panel data set includes the fourteen G-20 countries during the period 1991–2012. Empirical results show that the marginal effects of the macroeconomic variables (savings, terms of trade, public debt, capital account liberalization, economic growth, and trade openness) on international reserves are non-linear and vary with time, the proxies and countries, not linear and constant derived from traditional linear model. Currency devaluation policy (against the US dollar) can non-linearly enlarge the positive contribution of trade openness and public debt on international reserves, and non-linearly reduce the negative impact of terms of trade on international reserves, as the Marshall–Lerner condition holds. Expansionary monetary policy (through the decrease in domestic interest rates) can strengthen the positive effects of public debt, trade openness, and economic growth on international reserves. The precautionary and mercantilist views of reserves holdings are partially supported.     

Trade deficits in the Baltic states: How long will the party last?

Since their opening up to international capital markets, the economies of Estonia, Latvia and Lithuania have experienced large and persistent capital inflows and trade deficits. This paper investigates whether a calibrated two-sector neoclassical growth model can explain the magnitudes and the timing of the trade flows in the Baltic states. The model is calibrated for each of the three countries, which we simulate as small closed economies that suddenly open up to international trade and capital flows. The results show that the model can account for the observed magnitudes of the trade deficits in the 1995–2004 period. Introducing a real interest rate risk premium in the model increases its explanatory power. The model indicates that trade balances will turn positive in the Baltic states around 2010.     

Effect of World Fertility Scenarios on International Living Standards

This paper applies a two good, multi-region Ramsey-Solow model of the world economy to determine the impact that alternative world fertility rates would have on international capital markets and living standards. Notable features of the model include: relative consumption demands and relative employment efficiencies that vary by age, traded and non-traded goods, vintage technology, outward-looking reference consumption, a proportion of non-optimising rule-of-thumb consumers and imperfect capital mobility due to asymmetric information. The model suggests that projected demographic change will imply a flow of international capital from the ageing regions to the younger regions; and that the world interest rate will fall. The lower world interest rate will cause a loss in living standards for ageing regions, the lenders, and a gain for the younger regions, who are borrowers.     

The illusive quest: Do international capital controls contribute to currency stability?

We investigate the effectiveness of capital controls in insulating economies from currency crises, focusing in particular on both direct and indirect effects of capital controls and how these relationships may have changed over time in response to global financial liberalization and the greater mobility of international capital. We predict the likelihood of currency crises using standard macroeconomic variables and a probit equation estimation methodology with random effects. We employ a comprehensive panel data set comprised of 69 emerging market and developing economies over 1975–2004. Both standard and duration-adjusted measures of capital control intensity (allowing controls to “depreciate” over time) suggest that capital controls have not effectively insulated economies from currency crises at any time during our sample period. Maintaining real GDP growth and limiting real overvaluation are critical factors preventing currency crises, not capital controls. However, the presence of capital controls greatly increases the sensitivity of currency crises to changes in real GDP growth and real exchange rate overvaluation, making countries more vulnerable to changes in fundamentals. Our model suggests that emerging markets weathered the 2007–2008 crisis relatively well because of strong output growth and exchange rate flexibility that limited overvaluation of their currencies.

Financial frictions,interest rate dynamics,and international business cycle synchronization

A two‐country real business cycle model with national endogenous borrowing constraints and working capital requirements can account for the high level of international co‐movements. The effects of technology shocks are transmitted internationally through the dynamics of the interest rate. Specifically, the borrowing mechanism brings about a wedge between the real interest rate and the expected marginal product of capital, such that interest rates fall following positive technology shocks. A lower interest rate induces more investment by Foreign firms, which in turn contribute to greater synchronization of economic activities across countries. Moreover, terms of trade amplify the effects of technology shocks.     

International capital flows and convergence in the neoclassical growth model

To analyze how capital mobility affects economic growth and convergence, this paper will use the analytical solution to the neoclassical growth model with a constant saving rate, beginning with the closed-economy Solow growth model. An introduction to international capital flows will follow. In an open economy, free capital mobility assures an instantaneous convergence in interest rates that, under a perfect competence situation, implies the instantaneous convergence in income levels among homogeneous countries. Taking into account this question and to reconcile these results with empirical evidence, that is, with the gradual convergence observed, the assumption is introduced that in spite of free capital mobility, there are international credit restrictions. In this case, we will show how the rate of convergence depends on the international capital inflows received.

How trade and capital restrictions affect the probability of a balance of trade disturbance

Free market economists argue that national authorities avoid restrictions on the free movement of goods, services and financial capital between countries. Yet, countries continually choose to restrict the flow of capital both into and out of the country. Why is this done? Is it done to protect the domestic banking system, to control the domestic money supply, to manage the exchange rate, to provide stability for internal markets or to avoid wide swings in the availability of capital? Are these controls effective in precluding wide swings in a country's international trade balance? This article uses panel data in a logit model to analyse policy choice with respect to an international trade and/or investment regime. The goal is to identify choices effective in reducing the likelihood of a severe Balance of Trade Disturbance (BTD) and determine if the appropriate choice is related to per capita income (pci).     

Capital controls and welfare with cross-border bank capital flows

This performance of time-varying capital controls on cross-border bank borrowing is studied in an open-economy, dynamic stochastic general equilibrium model with financial frictions and imperfect capital mobility. The model is parameterized for a middle-income country and replicates the stylized facts associated with a drop in world interest rates—capital inflows, real appreciation, credit boom, asset price pressures, and output expansion. A capital controls rule, which is fundamentally macroprudential in nature, is defined in terms of changes in bank foreign borrowing. The welfare-maximizing rule is established numerically and compared to the Ramsey policy. The analysis is then extended to solve jointly for optimal countercyclical reserve requirements and capital controls rules. The results show that the implementation of a countercyclical credit-based reserve requirement rule induces less reliance on capital controls. Thus, these two instruments are partial substitutes in maximizing welfare.     

Institutional Features of Schooling Systems and Educational Inequality: Cross‐Country Evidence From PIRLS and PISA

Educational opportunities determine the intergenerational mobility of human capital and affect the distribution of earnings on the labour market. This paper aims at explaining cross‐country differences in educational opportunities by features of schooling systems. The theoretical model predicts that a greater differentiation of the schooling system as indicated by streaming and a large share of private schools decreases educational opportunities while more instruction time increases educational opportunities. The empirical results that are based on a difference‐in‐differences estimation approach to control for country‐specific effects support these hypotheses.
