不同的政策不确定性对股市波动影响相同吗?

本文基于多因子混频波动率模型,研究经济政策不确定性对股市行业波动的影响,为预防出现结构性断点,将样本分为经济增长和经济平稳两个时期,分别探讨两个时期内经济政策不确定性对股市波动的影响。研究发现,在全样本时期货币政策不确定性会显著增强行业波动,贸易和外汇政策不确定性会抑制行业波动,而财政政策不确定性的影响存在行业差异性;子样本结果显示,贸易政策不确定性对行业波动的影响存在非对称性,在经济增长期存在助推作用,在经济平稳期存在抑制作用;同时行业波动在经济增长期对贸易政策反应敏感,在经济平稳期对财政政策反应敏感。     

“稳增长”与“防风险”双目标的宏观调控政策抉择

“防风险”和“稳增长”是当前宏观调控的两大政策目标,为此,本文构建一个平衡兼顾双重政策目标的门限理论模型框架,基于反事实方法评估了动态平衡上述两大目标的最优财政货币政策组合。研究表明:(1)2008年以前,财政政策和货币政策都表现出较强的稳增长政策功效,但国际金融危机后,政策取向更倾向于动态平衡“稳增长”与“防风险”目标。(2)财政政策对三部门杠杆的影响呈现显著增强态势,数量型货币政策效果则在经历“增加—下降”周期后趋于稳定,利率政策效果显著而且近年来呈现增强态势,由此表明利率的传导效果正在不断得以强化。(3)从反事实结果看,宏观调控的最优政策搭配抉择取决于政策当局在动态平衡不同目标中的政策取向,特别是,依赖于精准调控“稳增长”与“防风险”目标的偏好强度。     

FISCAL DEFICITS AND MACROECONOMIC PERFORMANCE IN DEVELOPING COUNTRIES

Although fiscal adjustment was urged on developing countriesduring the 1980s to lead them out of economic malaise, considerableuncertainty remains about the relations between fiscal policyand macroeconomic performance. To illustrate how financial markets,private spending, and the external sector react to fiscal policies,the behavior of holdings of money and public debt, private consumptionand investment, the trade balance, and the real exchange rateis modeled for a sample of ten developing countries. The studiesfind strong evidence that over the medium term, money financingof the deficit leads to higher inflation, while debt financingleads to higher real interest rates or increased repressionof financial markets, with the fiscal gains coming at increasinglyunfavorable terms. Consumers respond differently to conventionaltaxes, unconventional taxes (through inflation or interest andcredit controls), and debt financing, in ways that make fiscaladjustment the most effective means of increasing national saving.Private investment—but not private consumption—issensitive to the real interest rate, which rises under domesticborrowing to finance the deficit. Contrary to the popular presumption,in some countries private investment increases when public investmentdecreases. There is strong evidence that fiscal deficits spillover into external deficits, leading to appreciation of thereal exchange rate. Fiscal deficits and growth are self-reinforcing:good fiscal management preserves access to foreign lending andavoids the crowding out of private investment, while growthstabilizes the budget and improves the fiscal position. Thevirtuous circle of growth and good fiscal management is oneof the strongest arguments for a policy of low and stable fiscaldeficits.      

Sovereign risk,public debt,dollarization, and the output effects of fiscal austerity

The goal of this paper is to investigate effects of fiscal policy on output as a response to an external shock at different levels and currency compositions of public debt. Central to our analysis is the mutual relationship between sovereign risk and public debt on the one hand, and the linkage between sovereign risk and private credit spreads on the other. We show that fiscal austerity is conducive to real economic activity when initial government debt is high, its foreign currency share is important, and the link between sovereign and corporate spreads is strong.     

Supersanctions and sovereign debt repayment

What might happen if a third-party entity had the power to implement fiscal reforms and/or punish sovereign debt defaulters? In contrast to recent history, extreme sanctions such as gunboat diplomacy and “fiscal house arrest” were used to punish debt defaulters during the period 1870–1913. We find that, after a “supersanction” was imposed, a country improved its fiscal discipline. As a result, ex ante default probabilities on new issues fell dramatically and the country spent no additional time in default. Our results suggest some type of external fiscal or monetary control may be effective in imposing discipline on serial debt defaulters.     

Fiscal Stimulus in Times of High Debt: Reconsidering Multipliers and Twin Deficits

We investigate the impact of fiscal stimuli at different levels of the government debt‐to‐GDP ratio for a sample of 17 European countries from 1970 to 2010. This is implemented in an interacted panel VAR framework in which all coefficient parameters are allowed to change continuously with the debt‐to‐GDP ratio. We find that responses to government spending shocks exhibit strong nonlinear behavior. While the overall cumulative effect of a spending shock on real GDP is positive and significant at moderate debt‐to‐GDP ratios, this effect turns negative as the ratio increases. The total cumulative effect on the trade balance as a share of GDP is negative at first but switches sign at higher levels of debt. Consequently, depending on the degree of public indebtedness, our results accommodate long‐run fiscal multipliers that are greater and smaller than one or even negative as well as twin deficit and twin divergence behavior within one sample and time period. From a policy perspective, these results lend additional support to increased prudence at high public debt ratios because the effectiveness of fiscal stimuli to boost economic activity or resolve external imbalances may not be guaranteed.     

财政限制下政府债务与通货膨胀研究

随着人口老龄化,许多发达经济体都步入了财政压力时代,政府对养老金的承诺大大高于财政收入,政府为了实现承诺将利用发行新债务进行融资,这将带来未来的高税收预期.随着债务水平和税率水平的上升,人们对税收的容忍度将下降,从而触碰财政限制的可能性增大.在采取固定税率情况下,调整税收不再能稳定债务,必须采取政策转变来应对.在财政限制之前债务增长与政策调节如何相互作用,若采用货币政策的被动调节来满足稳定债务,那么政府债务将影响到通货膨胀,从而使货币政策失去对通货膨胀的控制,进而需要通过财政政策来解决通胀问题.     

宏观经济调控：直行还是转向？

今年以来,受国内外多种因素的影响,国内经济出现放缓迹象,稳增长继而被摆在更加重要的位置,但业界也出现了对当前宏观调控政策取向中是否应有更多刺激经济政策的分歧。文章指出,目前中国经济运行中的困难不同于2008年国际金融危机期间的情形,其主要是中国经济内在结构调整和政府宏观调控的结果,也有欧债危机冲击的因素。应对目前经济困难格局的政策空间较大,手段充裕,我们完全有条件在坚持积极财政政策和稳健货币政策的同时,处理好保增长、促就业和调结构的平衡关系。     

财政分权与经济增长可持续性——基于情势转换与聚类视角的分析

经济增长可持续性不仅取决于增长速度还取决于增长稳定性。本文利用我国245个地级市1978—2014年间面板数据和马尔科夫情势转换聚类面板模型,从情势转换与聚类视角考察了地级市经济增长动态特征,识别出不同的动态增长模式及其可持续性,进而剖析了财政分权的影响。研究表明,地级市经济增长呈现出三种动态增长模式,这三种模式在平均增速、增长状态及其持续期、增长波动性进而在增长可持续性方面存在明显差异。支出分权显著增加了地级市归属为低增长、高波动模式的概率,不利于经济可持续增长,而在1994年分税制改革后则产生了较积极的作用。收入分权总体有利于增强经济增长可持续性,1994年分税制改革后,受地方纵向财政失衡加剧的不利影响,这一积极作用有所减弱。增加地方财政自给度(即增加地方收支分权匹配度、减小地方纵向财政失衡)有利于增强经济增长可持续性,这一作用在1994年分税制改革后表现得更为突出。本文研究结论对优化完善财税体制以有效促进经济可持续增长具有良好启示。     

人口老龄化、养老保险基金缺口弥补与经济增长

本文构建一个包含财政支出和公共债务的世代交叠模型,以养老保险基金缺口弥补为核心内容,考察人口老龄化对经济增长的影响,并探讨采用何种基金缺口弥补方式更有利于促进经济增长。研究发现,若采用财政补贴方式弥补基金缺口,生存概率上升和生育率下降均提高经济增速;若采用发行公债方式或两者兼用方式弥补基金缺口,当人力资本产出弹性较小时相应结论不变,反之则经济增速随生存概率上升呈倒U型变化趋势,随生育率下降而提高。基金缺口弥补方式是影响经济增长的重要制度因素,人力资本产出弹性较小时发行公债方式下的经济增速最高,反之则为财政补贴方式。结合我国现实,本文认为政府应探索包括发行公债在内的多种基金缺口弥补方式以更好地应对人口老龄化,实现经济长期较快增长。     

On the need for fiscal constraints in a monetary union

The desirability of fiscal constraints in monetary unions depends critically on whether the monetary authority can commit to following its policies. If it can commit, then debt constraints can only impose costs. If it cannot commit, then fiscal policy has a free-rider problem, and debt constraints may be desirable. This type of free-rider problem is new and arises only because of a time inconsistency problem.

2011年全球经济与市场回顾和2012年展望

2011年,受欧洲主权债务危机不断蔓延的影响,发达国家经济复苏缓慢并呈现逐步分化趋势,新兴市场国家作为全球经济复苏主引擎的作用仍然突出,但也面临着经济增长趋缓的困扰。2012年,由于欧债危机隐患未除、全球金融系统依然脆弱以及发达国家自身结构性问题远未解决,全球经济方向将面临较大不确定性。未来新兴市场经济体有望继续充当全球经济复苏的主要动力,但增速将趋于放缓。发达经济体将维持宽松的货币政策,并将迫于财政赤字压力采取财政紧缩措施,而新兴经济体预计将实施相对稳健的货币政策与较为宽松的财政政策,以应对通货膨胀和经济增速趋缓的双重压力。     

Fiscal Fan Charts: A Tool for Assessing Member States' (Likely?) Compliance with EU Fiscal Rules

This paper sets out a methodology for constructing fan charts for the government deficit and debt ratios over the medium term. It relies on information contained in Stability/Convergence Programme Updates, a model of the relevant stochastic process (for example, that of real GDP) or processes, and a parameter estimate of the sensitivity of the primary budget balance to the output gap for the member state under consideration. A model of the dynamic deficit–debt relationship allows the impact of random output growth to work its way through the fiscal arithmetic in a consistent and traceable way to produce fan charts over a five‐year forecast horizon. The initial set of fiscal fan charts included here for Ireland use the indicative public finance projections set out in its 2011 Update. The methodology makes the standard assumption of no fiscal policy response to any change in the budgetary position over the period such as could arise from changes in growth rates. Governments will, however, generally be in a position to adjust fiscal policy towards meeting a specific target, such as the 3 per cent Maastricht Treaty deficit target. A second set of fan charts is included that indicates how the probabilistic range of fiscal outcomes could be affected by a tightening of fiscal policy in 2013–15.     

Cross‐Country Spillovers from Fiscal Consolidations

In the aftermath of the global financial crisis, many OECD countries adopted fiscal consolidation strategies to reduce their debt‐to‐GDP ratios. This paper investigates the effects of fiscal consolidation on trading partners’ growth through trade linkages. Using a measure of exogenous fiscal shocks in export markets, fiscal consolidation spillovers are found to slow down domestic growth and decrease employment. To the extent that fiscal consolidations are synchronised, fiscal policies have large spillover effects on output. Spillovers of fiscal consolidations on growth are found to be initially larger between countries belonging to currency unions, though this larger impact vanishes over the medium term. Larger spillovers of fiscal consolidation coincide with lower bilateral exports, higher bilateral imports and relative increases in unit labour costs in currency unions. Spillovers of fiscal consolidation are also found to be more detrimental to domestic growth during economic downturns in export markets.     

Debt, Death and Taxes

Does the level of government debt affect living standards and if so, to what extent? We quantify the impact of the U.S. federal debt using an open economy overlapping generations model in which consumers have long but finite lifetimes. A demographic structure allows fiscal policy changes to have different effects on different agents, and reveals the linkages between public debt, output and international trade. We find that reducing the debt has relatively modest impacts on aggregates, while reducing government spending substantially raises U.S. incomes and welfare. Therefore, this paper contributes to the current debate regarding whether U.S. federal government budget surpluses should be used to retire government debt.     

A Macrofinance View of U.S. Sovereign CDS Premiums

Premiums on U.S. sovereign credit default swaps (CDS) have risen to persistently elevated levels since the financial crisis. We examine whether these premiums reflect the probability of a fiscal default—a state in which a balanced budget can no longer be restored by raising taxes or eroding the real value of debt by increasing inflation. We develop an equilibrium macrofinance model in which the fiscal and monetary policy stances jointly endogenously determine nominal debt, taxes, inflation, and growth. We show that the CDS premiums reflect the endogenous risk-adjusted probabilities of fiscal default. The calibrated model is consistent with elevated levels of CDS premiums but leaves dynamic implications quantitatively unresolved.     

Fiscal hedging with nominal assets

We analyze optimal fiscal and monetary policy in an economy with distortionary labor income taxes, nominal rigidities, nominal debt of various maturities and short-selling constraints. Optimal policy prescribes the almost exclusive use of long term debt. Such debt mitigates the distortions associated with hedging fiscal shocks by allowing the government to allocate them efficiently across states and periods.     

货币、财政和宏观审慎政策的协调搭配研究

本文通过构建包含多部门和多元宏观政策的DSGE模型,对货币政策、财政政策和宏观审慎政策的最优反应规则及其协调组合问题进行了分析。分析结果显示:(1)从社会福利最大化的角度,货币政策可继续盯住通胀和产出的稳定,政府支出和税收政策可分别重点盯住产出稳定和债务稳定,而宏观审慎政策则可重点关注以信贷利差和信贷波动为代表的关键金融变量;(2)货币政策、财政政策和宏观审慎政策,通过合理的搭配和组合使用,能比任何单一政策工具都具有更好的经济金融稳定效应;反之,政策之间的不协调将显著削弱彼此的调控效应,加大经济和金融波动,从而导致显著的社会福利损失;(3)从多种政策协调搭配产生“合力”的内在机制来看,财政政策主要通过增加对产出、通胀、就业和债务等变量的稳定效应,对货币政策产生额外助力,而宏观审慎政策则主要通过稳定金融体系和降低金融风险对货币政策产生助力。上述结论表明,在多种经济金融政策并存的情况下,基于良好设定的政策规则,同时加强政策各部门之间的协调合作,是确保多元政策产生积极合力的重要基础。     

A modern history of fiscal prudence and profligacy

Drawing on a newly collected historical dataset of fiscal stocks and flows, we analyze the determinants of variation, both across countries and over time, in how fiscal policy responds to increases in the government debt-to-GDP ratio. The fiscal data comprise revenues, primary expenditures, interest bill, and government debt for 55 countries for up to two hundred years. The policy response (increase in the primary fiscal balance in response to debt increases) is found to be significantly weaker when sovereign borrowing costs are low, inflation is high, and potential economic growth worsens unexpectedly. These results are robust to political factors.
