Capital mobility and the effectiveness of fiscal policy in open economies

This paper uses a dynamic general equilibrium two-country optimizing ‘new-open economy macroeconomics’ model to analyze the consequences of international capital mobility for the effectiveness of fiscal policy. Conventional wisdom suggests that higher capital mobility diminishes the effectiveness of fiscal policy. The model laid out in this paper provides an example that a higher degree of capital mobility can also increase the effectiveness of fiscal policy. This tends to be the case if the stance of monetary policy can be described by means of a simple monetary policy rule.     

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.     

Capital inflows, fiscal discretion, and exchange rate policy

Many writers have argued for the benefits of a credible fixed exchange rate (a hard peg) as a commitment device in an open economy. But historically, fixed exchange rates have often been associated with large current account deficits and episodes of ‘over-borrowing’. This paper develops a model of capital inflows that are linked to the exchange rate regime because of endogenous fiscal policy. The key message of the paper is that a hard peg is undesirable in the absence of commitment in fiscal policy. In face of a credible fixed exchange rate, the fiscal authority subsidizes capital inflows. The economy will engage in inefficiently high international borrowing, and in welfare terms may end up worse off than under capital market autarky. To eliminate the incentive to subsidize borrowing, the monetary authority must follow a flexible exchange rate rule in which capital inflows lead to exchange rate appreciation. If fiscal policy must be financed by money creation rather than direct taxation, then a fixed exchange rate rule may cause both over-borrowing and a subsequent exchange rate crisis.     

RE-EXAMINING THE EFFECTIVENESS OF STABILISATION POLICY

This paper develops an alternative international macroeconomic model for evaluating the effectiveness of fiscal and monetary policy in stabilising national income under fixed and floating exchange rates. It encompasses national output and income, saving, investment, money and capital flows and linkages between the exchange rate, price levels and real interest rates consistent with international parity conditions. It demonstrates that the nature of government spending is pivotal to the effectiveness of fiscal policy, revealing that, ceteris paribus , higher public consumption expenditure contracts national income and depreciates the exchange rate, whereas higher productive public investment spending has opposite effects. The framework also shows that the effectiveness of fiscal and monetary policy as macroeconomic policy instruments is not ultimately dependent on the exchange rate regime.     

The effects of economic policy uncertainty on China’s economy: evidence from time-varying parameter FAVAR

ABSTRACT

This article explores the effects of China’s economic policy uncertainty (EPU) on its fiscal policy, monetary policy and a wide range of macro-economic variables using a time-varying parameter FAVAR model. Based on monthly data from 07/2003 to 08/2017, the time-varying structure of the model allows us to capture the time-varying characteristics of the macro-economic variables and which channel is relevant. Empirical results reveal that the reaction of monetary and fiscal policies to EPU is highly asymmetric across macro-economic circumstances. Loose monetary and fiscal policies are adopted in response to EPU shocks during the financial crisis, while policies are moderately tightened after the crisis. The China Interbank Offered Rate (Chibor) responds more sensitively and severely than M2 to EPU shocks. Additionally, EPU shocks have a significant and negative impact on economic growth, consumption, exchange rates, bonds and the stock market, but showing a positive impact on credit, real estate and fixed asset investment (which might be due to China’s special economic market environment and the high investment return). The results indicate that EPU shocks significantly affect macroeconomic fundamentals through precautionary savings and financial market channels but lose their effectiveness through a ‘real options’ effect.     

A Case for Managed Exchange Rates*

The incorporation of adaptive expectations by Dornbusch in a Mundell-Fleming model modifies significantly the traditional results of policy effectiveness in a small, open economy. While monetary policy is still able to influence aggregate demand when flexible exchange rates prevail, the effects of this policy on other important variables in the economy during the adjustment process to a new equilibrium may be considered sufficiently ‘disruptive’ so that the authorities will be hesitant to use their only fully-effective policy instrument for income-stabilization purposes. However, by adding a target level for the exchange rate to their list of goal variables and by using an appropriate mix of monetary and fiscal policies, it appears to be possible for the government to avoid these disruptive side effects.     

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.     

Neoliberal growth models,monetary union and the Euro crisis. A post-Keynesian perspective

The paper offers an account of the Euro crisis based on post-Keynesian monetary theory and its typology of demand regimes. Neoliberalism has transformed social and financial relations in Europe but it has not given rise to a sustained profit-led growth process. Instead, growth has relied either on financial bubbles and rising household debt (‘debt-driven growth’) or on net exports (‘export-driven growth’). In Europe the financial crisis has been amplified by an economic policy architecture (the Stability and Growth Pact) that aimed at restricting the role of fiscal policy and monetary policy. This neoliberal economic policy regime in conjunction with the separation of monetary and fiscal spheres has turned the financial crisis of 2007 into a sovereign debt crisis in southern Europe.     

Financial distress and fiscal inflation

Is inflation ‘always and everywhere a monetary phenomenon’ or is it fundamentally a fiscal phenomenon? The answer hinges crucially on the underlying monetary–fiscal policy regime. Scant attention has been directed to the role of credit market frictions in discerning the policy regime, despite its growing importance in empirical macroeconomics. We augment a standard monetary model to incorporate fiscal details and credit market imperfections. These ingredients allow for both interpretations of the inflation process in a financially constrained environment. We find that introducing financial frictions to the model and adding financial variables to the dataset generate important identifying restrictions on the observed pattern between inflation and measures of financial and fiscal stress, to the extent that it overturns existing findings about which monetary–fiscal policy regime produced the U.S. data. To confront policy regime uncertainty, we propose the use of dynamic prediction pools and find strong cyclical patterns in the estimated historical regime weights.     

Unconventional monetary policy and capital flows

This paper examines the connection between the stance of domestic monetary policy and international capital flows. It first provides a simple theoretical framework describing the mechanisms behind the cross-border spillovers of domestic monetary policy. Then, it empirically investigates the impact of U.S. unconventional monetary policies (UMPs), implemented in the aftermath of the recent global financial crisis, on U.S. capital flows to developing economies and non-UMP advanced economies. The results suggest that the use of quantitative easing by the Federal Reserve has been associated with increased net portfolio flows to developing countries and, to a lesser extent, non-UMP advanced economies. An exit from these UMPs is likely to cause capital flow reversals in U.S. capital-importing countries. Countries with greater exchange rate flexibility, stronger fiscal and current account positions, and higher capital mobility are likely to fare well following an exit from UMPs in the U.S.     

汇率制度与宏观经济政策环境——以加拿大为例

加拿大属于典型的资源性经济,加元的汇率变化多受国际商品和石油价格的影响,超出了国内货币政策的控制范围,是独立浮动或是固定汇率？经过两次试验后,加拿大政府坚定地选择了独立浮动汇率制度,并最终实现了汇率政策与货币政策脱离,以此给予了加拿大银行较大的决策空间,使后者专注于维持较低的通货膨胀环境。同时,加拿大政府努力为汇率制度创造有利的宏观经济政策环境,财政政策和货币政策分工明确、相互支持,为汇率制度和经济增长奠定了可持续的坚实基础。本文以加拿大浮动汇率制度为主线,从财政政策、货币政策、政策搭配角度讨论其宏观经济政策框架,分析加元汇率制度的运行环境。在此基础上,本文探讨加拿大汇率政策及浮动汇率制度的作用与功能。本文第五部分对加拿大银行提出的汇率预测模型作出了较深入的分析。     

Economic Growth,Terms of Trade and Welfare in an Open Monetary Economy*

The authors investigate the impact of growth on terms of trade, absolute prices and welfare using a two-country, monetary model. Under flexible exchange rates export-biased growth would lead to a decline in the terms of trade if the two countries are ‘similar’. Under fixed exchange rates a weaker condition than the barter condition of export-biased growth is sufficient, namely, for the import commodity the demand creating effect of growth dominates the supply effect while for the exported commodity the opposite holds. Secondly, substitutability between money and commodities indicates that no necessary relation holds between the terms of trade and the trade balance. Thirdly, the introduction of money creates a real balance effect so that decline in terms of trade is no longer a necessary (or sufficient) condition for immiserization. Finally, the paper concludes by questioning two policy conclusions drawn in earlier models: one, that the declining terms of trade of less developed countries was due to a bias in the growth strategy and, two, that monetary models of trade support the ‘monetarist’ proposition that growth and a deteriorating trade balance can only co-exist if the domestic monetary policy is nonneutral.     

Understanding the dynamics of the macroeconomic trilemma

This paper tests the autonomy of domestic monetary policy in the context of the macroeconomic policy trilemma for a large data-set of developing and developed countries covering three different time periods characterized with different exchange rate regimes and capital controls. The existing literature uses fixed coefficient methodologies to examine monetary policy independence; whereas we show that the coefficients of interest are unstable as countries switch between different exchange rate regimes and/or capital controls over time. The contribution is in using a time-varying parameter model that better captures the effects of the heterogeneity in different exchange rate regimes and capital mobility restrictions on monetary policy independence over time, allowing a more accurate test of the macroeconomic trilemma.     

土地政策参与宏观调控的政策工具研究——基于主体功能区建设的理论探索

自2003年我国明确提出土地政策参与宏观调控以来,国家出台了许多土地政策调节经济。然而与传统的财政政策和货币政策两大宏观调控政策不同的是,土地政策在经典义宏观经济学中却缺少必要理论基础,其参与宏观调控的机制也揭示不足。若要使土地政策成为真正意义上的主流调控手段,则需解决土地的空间性和不可再生性两个难题。因此,可通过技术进步向空间和地下两个方向发展、增强土地的利用率;还可将资本和劳动等要素的自由灵活流动与不可流动的土地要素结合,将土地政策与其他政策相配合,使土地政策成为宏观调控的手段。     

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.     

The transmission of bank capital requirements and monetary policy to bank lending in Germany

We investigate the transmission of changes in bank capital requirements and monetary policy, and their interaction, on German banks’ corporate loan growth and lending rates. Our results show that increases in capital requirements are associated with an immediate decrease in total domestic and cross‐border bank lending. Changes in the euro area's monetary policy stance are positively related to corporate loan interest rates in general. Regarding the interacting effect of national bank capital requirements and euro area monetary policy, we observe that the transmission of accommodative euro area monetary policy to corporate lending rates can be attenuated by contemporaneous increases in bank capital requirements. Moreover, more strongly capitalized banks increase their loan growth in response to accommodative monetary policy whereas, for weaker banks, increasing capital requirements implies a decrease in their corporate loan growth. Our results confirm a tradeoff between higher capital requirements and accommodating monetary policy originating from banks’ capital constraints.     

The Bernanke and Blinder Model in an Open Economy: The Italian Case

Abstract. This paper analyzes the functioning of monetary policy transmission mechanisms in Italy from 1984 to 1998, highlighting the role performed by the credit system. We extend the Bernanke and Blinder model (1988) to the case of an open economy under a quasi‐fixed exchange rate regime, deriving analytically the conditions for the functioning of the three monetary policy channels generally identified in the literature (‘money’, ‘exchange rate’ and ‘credit’). These conditions explain the partial effectiveness of monetary policy in achieving price and income targets, while maintaining external equilibrium. By means of a structural VECM analysis, we evaluate the effectiveness of the transmission of monetary policy through the three channels.     

The role of fiscal policy in the St. Louis model: Nonparametric estimates for a small open economy

This paper reevaluates the efficacy of monetary and fiscal policies and bidirectional causality between income and each of the policy instruments used in the St. Louis model for aggregate demand using nonparametric (or infinite parametric) spectral methods. We proceed by estimating the strength of the correlations (or partial coherences) between income and each of the policy instruments over various frequencies. Then we obtain the corresponding band regression and Hannan's efficient estimates of both the lead and lag coefficients in the St. Louis model. The analysis is carried out with seasonally adjusted quarterly data and is divided into the flexible, fixed, and managed flexible exchange rate regimes. We find that while estimates from parametric regressions yield the standard conclusions for the St. Louis model, results from the nonparametric analysis are quite different. Specifically, the results of our analysis reveal that (i) both monetary and fiscal instruments are strongly correlated with income over cycles of 10 quarters or longer for the most recent period of the managed flexible exchange rate regime, and (ii) bidirectional causality exists between income and the fiscal policy instrument. These results suggest that both monetary and fiscal policy have a long-lasting effect on aggregate demand and that bidirectional causality exists between income and policy instruments. An explanation for the existence of bidirectional causality might be that the Canadian government generally pursued a purposeful discretionary fiscal policy during the post-World War II period. Furthermore, it appears that discretionary policy action may have been anticipated by rational, farsighted, and forward-looking economic agents. Finally, our results for the flexible exchange rate and fixed rate regimes are in agreement with the Mundell-Fleming view of the role of monetary fiscal policy in an open economy.     

Global capital markets,direct taxation and the redistribution of income

Standard fiscal theory suggests that taxation should be heaviest on the least mobile factors of production – for both efficiency and revenue reasons. A shift in tax burdens from capital to labour as economies become globally integrated is thus justified. This theoretical tradition (founded by Ramsay and continued by Mirrlees and Lucas) assumes by construction that profit taxes reduce investment and growth; and while sensitive to inter-generational equity, sidesteps the issue of income distribution within generations. In contrast, starting from Keynes’ critique of these assumptions and building on modern endogenous growth models, it can be shown that profit taxation is not necessarily injurious to productive investment. In practice, moreover, the effect of globalisation has not been to reduce tax rates on capital, but rather to erode the tax base itself (i.e. ‘tax evasion’). Improved information exchange between tax authorities, which is now being driven by fiscal insolvency in developed countries, would allow tax incidence to be shifted so as to improve income distribution within OECD countries. Such cooperation could also permit the replacement of the current discretionary system of fiscal transfers from rich to poor countries (‘development aid’) by equitable sharing of global capital tax revenue.     

The optimal choice of monetary policy instruments in a small open economy

Abstract.  This paper studies how the nature of shocks affects the optimal choice of monetary policy instruments in a small open economy. Three classic rules, fixed exchange rates, monetary targeting, and inflation targeting are studied and ranked by comparing with the optimal monetary policy under commitment. We find that the ranking of the simple rules can be mapped to the terms-of-trade variability that the rule allows relative to what a particular shock optimally calls for. It turns out that inflation targeting dominates the other two rules under productivity or velocity shocks, whereas monetary targeting is the best performer under fiscal shocks.
