欧债危机的现状评估、政策选择与演进前景

文章首先评估了欧债危机的发展现状,包括欧洲危机的演进历程、潜在冲击以及对欧洲银行业造成的挑战;其次剖析了当前应对欧债危机的各种政策选择,包括利用EFSF/ESM机制、IMF的参与、发行欧洲债券以及由ECB担任最后贷款人,并分析了各种政策选择面临的制约因素;最后展望了欧债危机的三种可能前景:财政一体化、欧元区解体以及维持现状,并指出财政一体化前景的概率最高。     

Inflation and the fiscal limit

We use a rational expectations framework to assess the implications of rising debt in an environment with a “fiscal limit”. The fiscal limit is defined as the point where the government no longer has the ability to finance higher debt levels by increasing taxes, so either an adjustment to fiscal spending or monetary policy must occur to stabilize debt. We give households a joint probability distribution over the various policy adjustments that may occur, as well as over the timing of when the fiscal limit is hit. One policy option that stabilizes debt is a passive monetary policy, which generates a burst of inflation that devalues the existing nominal debt stock. The probability of this outcome places upward pressure on inflation expectations and poses a substantial challenge to a central bank pursuing an inflation target. The distribution of outcomes for the path of future inflation has a fat right tail, revealing that only a small set of outcomes imply dire inflationary scenarios. Avoiding these scenarios, however, requires the fiscal authority to renege on some share of future promised transfers.     

When do more selfish politicians manipulate less,not more?

We model the political manipulation of deficits in a political budget cycle model. Assuming that a share of voters suffers from debt illusion the incumbent can increase her re-election chances by expanding government spending. However, the optimal manipulation may exceed the amount necessary to maximize re-election chances (over-manipulation) if the deficit is not very costly (low repayment obligation). Then, more selfish politicians (higher ego rents and, therefore, increased re-election motivation) reduce the over-manipulation. Conversely, “excessive” spending may wrongly be interpreted as opportunistic government manipulation. Theoretical results are supported empirically, with very robust evidence in a sample of 87 democracies.     

国债与宏观经济的动态分析

本文在总结国内外有关文献的基础上,构建了国债与利率、通货膨胀的动态稳定性分析理论框架,并利用月度VAR模型检验我国国债余额与短期利率、通货膨胀的关系,发现国债虽对实际利率和通货膨胀有一定作用,但影响小得可以忽略不计,说明改革开放以来的中国财政总体是稳定的,最后是简短的结论和政策建议。     

Fiscal policy in the US: Sustainable after all?

The sustainability of US public debt has been widely discussed since the Great Recession. Using annual data since 1940, we estimate and compare different specifications of fiscal rules. Estimates of constant-parameter fiscal rules show no evidence of sustainability. This may be due to the instability of government's behaviour over time. Thus, we estimate a Markov-switching fiscal rule in order to identify periods of unsustainable and sustainable fiscal policies. First, we show that the government stabilizes public debt only periodically. Second, during these periods, the government's reaction is sufficiently tight to stabilize public debt over the entire horizon. We conclude that a relatively short-lived but tight fiscal contraction can be sufficient to ensure long-run US debt sustainability.     

关于“双顺差”背景下实现中国内外均衡的思考

内外均衡目标是指充分就业、物价稳定、经济增长及国际收支均衡。目前，中国正面临通货紧缩的压力和国际收支双顺差的格局，因此需通过扩张性的财政及货币政策进行协调，同时辅以汇率及利率政策。只有内外兼顾统一才能使经济实现稳定发展。     

Do Government Purchases Affect Unemployment?

We estimate the effect of government purchases on unemployment in 20 OECD countries, for the period 1980–2007. An increase in government purchases, equal to 1 percent of GDP, is found to reduce unemployment by about 0.3 percentage points in the same year. The effect is greater and more persistent under less “employment‐friendly” labour‐market institutions, and it is greater and more persistent under a fixed exchange rate regime than under a floating regime. The effect is also greater in downturns than in booms. The effect on unemployment reflects a corresponding positive effect of increased government purchases on the employment‐to‐population rate.     

The global dimension to fiscal sustainability

This paper provides a new perspective of fiscal sustainability and financial globalization in emerging and industrial countries. We highlight the importance of global capital market shocks for fiscal sustainability, a relationship which has hitherto been ignored in the empirical literature. Using a factor model we demonstrate that the relationship between deficit and debt is conditional upon a global factor and we suggest that this global factor is related to world-wide liquidity. We also demonstrate that this acts as a constraint on emerging market economies’ fiscal policy.     

Budget balances in OECD countries: what makes them change?

Fiscal balances have deteriorated quickly in recent years, bringing back to the foreground the question what factors explain such sharp changes. This paper takes a broad perspective at the issue regarding countries included, the range of potential explanatory variables, and the time-span covered. The empirical analysis shows that changes in budget balances are affected by debt growth, macroeconomic developments and political factors. In particular, we find that the run-up to EMU induced additional consolidation in Europe and that budget balances deteriorate markedly in election years. Asset prices also affect budgets, but the impact remains limited in normal times.      

财政分权视角下的地方政府债务研究:一个综述

本文通过在财政分权的框架下对地方政府债务的成因、影响、管控的相关理论分析和经验研究的梳理,总结了较为成熟的财政联邦经济体在地方债务管理实践中的经验教训,同时,也对正处于分权化改革当中的转型国家的地方政府债务问题进行了总结,并最终落脚到中国的地方政府债务问题上来。中国的地方政府债务问题因与分税制度不完善、地方官员激励扭曲、地方融资平台不规范、宏观调控和财政政策需要等问题联系在一起而更加错综复杂,需要在借鉴已有研究的基础上结合中国的现实制度特征做进一步深入研究。     

Differences in measures of the fiscal multiplier and the reduced-form vector autoregression

The literature has recently asked whether the effects of fiscal policy vary with the state of the economy (Christiano, Eichenbaum, and Rebelo 2011; Rendahl 2014; Auerbach and Gorodnichenko 2012). We study this question in the context of vector autoregression (VAR) estimation. We show formally that, if (asymptotically) the parameters of the reduced-form VAR differ, then the dynamic effects of fiscal policy differ as well, generically and for any set of identification assumptions. Thus, in theory, the econometrician can detect these differences (either across time or space) generically just by relying on reduced-form VAR estimation.     

Tax-spending policies and economic growth: Theoretical predictions and evidence from the OECD

We present an endogenous growth model to study the growth effects of the composition of government expenditure and the associated tax burden. When we use data from a set of 23 OECD countries during 1970–2000, our econometric results support the predictions of the theory. The share of productive government expenditure is associated with higher growth, and this result is more robust when we use effective average tax rates and statutory tax rates as measures of the tax burden. With respect to the tax burden, different tax rates have different growth effects.
