The Real Effects of Credit Ratings: The Sovereign Ceiling Channel

We show that sovereign debt impairments can have a significant effect on financial markets and real economies through a credit ratings channel. Specifically, we find that firms reduce their investment and reliance on credit markets due to a rising cost of debt capital following a sovereign rating downgrade. We identify these effects by exploiting exogenous variation in corporate ratings due to rating agencies' sovereign ceiling policies, which require that firms' ratings remain at or below the sovereign rating of their country of domicile.     

Fiscal Rules and Government Financing Costs

This paper assesses the effect of fiscal rules on sovereign bond spreads over the short and medium term, for 34 advanced countries and 19 emerging market economies, over the period 1980–2016. Our results, based on impulse response functions, show that the dynamic impact of fiscal rules on sovereign yield spreads is negative and statistically significant, at around 1.2–1.8 percentage points, implying lower government borrowing costs. This result stems essentially from the advanced economies subsample. We also find that more fiscally responsible countries are the ones for which a fiscal rule reduces the government's borrowing costs. Moreover, in times of recession, a fiscal rule leads financial markets to reduce the risk premiums on government bonds. Finally, when it comes to design features of fiscal rules, independent monitoring of compliance to the rule, done outside government, also reduces sovereign spreads.     

Sovereign ceilings “lite”? The impact of sovereign ratings on corporate ratings

Although credit rating agencies have gradually moved away from a policy of never rating a corporation above the sovereign (the ‘sovereign ceiling’), it appears that sovereign credit ratings remain a significant determinant of corporate credit ratings. We examine this link using data for advanced and emerging economies over the period of 1995–2009. Our main result is that a sovereign ceiling continues to affect the rating of corporations. The results also suggest that the influence of a sovereign ceiling on corporate ratings remains particularly significant in countries where capital account restrictions are still in place and with high political risk.     

Sovereign Credit Risk,Banks' Government Support,and Bank Stock Returns around the World

We explore the joint effect of expected government support to banks and changes in sovereign credit ratings on bank stock returns using data for banks in 37 countries between 1995 and 2011. We find that sovereign credit rating downgrades have a large negative effect on bank stock returns for those banks that are expected to receive stronger support from their governments. This result is stronger for banks in advanced economies where governments are better positioned to provide that support. Our results suggest that stock market investors perceive sovereigns and domestic banks as markedly interconnected, partly through government guarantees.

Uncertainty and Fiscal Cliffs

Large pending fiscal policy changes, such as in the United States in 2012 or in Japan with consumption taxes, often generate considerable uncertainty. “Fiscal cliff” episodes have several features: an announced possible future change, a skewed set of possible outcomes, the possibility that implementation may not actually occur, and a known resolution date. This paper develops a model capturing these features and studies their impact. Fiscal cliff uncertainty shocks have immediate impact, with a magnitude that depends on the probability of implementation, which generates economic volatility. The possibility of fiscal cliffs lowers economic activity even in periods of relative certainty.     

Economic policy uncertainty and short-term financing: The case of trade credit

We examine the impact of economic policy uncertainty on trade credit. We document a decline (increase) in accounts payable, receivable, and net credit during periods of high (low) policy uncertainty and that firms react quickly to changes in uncertainty. The relation is long-term and holds after controlling for endogeneity, non-policy economic and political uncertainties, and the Great Recession. Industry competitiveness, proxied by firm market power, moderates the impact of economic policy uncertainty on trade credit. Uncertainty about monetary and fiscal policies, taxes, and regulations are the major drivers of trade credit changes. The reduction in trade credit during periods of increasing uncertainty can be explained by financial distress, constraints, and relation-specific investment channels.     

Sovereign rating actions and the implied volatility of stock index options

This paper examines the interaction between the equity index option market and sovereign credit ratings. S&P and Moody's signals exhibit strong impact on option-implied volatility while Fitch's influence is less significant. Moody's downgrades reduce the market uncertainty over the rated countries' equity markets. Strong causal relationships are found between movements in the option-implied volatility and all credit signals released by S&P and Fitch, but only actual rating changes by Moody's, implying differences in rating agencies' policies. The presence of additional ratings tends to reduce market uncertainty. The findings highlight the importance of rating information in the price discovery process and offer policy implications.     

How effective are macroprudential policies? An empirical investigation

In recent years, policymakers have generally relied on macroprudential policies to address financial stability concerns. However, our understanding of these policies and their efficacy is limited. In this paper, we construct a novel index of macroprudential policies in 57 advanced and emerging economies covering the period from 2000:Q1 to 2013:Q4, with tightenings and easings recorded separately. The effectiveness of these policies in curbing credit growth and house price appreciation is then assessed using a dynamic panel data model. The main findings of the paper are: (1) Macroprudential policies have been used far more actively after the global financial crisis in both advanced and emerging economies. (2) These policies have primarily targeted the housing sector, especially in the advanced economies. (3) Macroprudential policies are usually changed in tandem with bank reserve requirements, capital flow restrictions, and monetary policy. (4) Our analysis suggests that macroprudential tightening is associated with lower bank credit growth, housing credit growth, and house price appreciation. (5) Targeted policies – for example, those specifically intended to limit house price appreciation – seem to be more effective, especially in economies where bank finance is important.

Fiscal and monetary policies and the cost of sudden stops

This article investigates the effects of monetary and fiscal policies on output growth during sudden-stop balance of payments crisis in emerging markets and developing countries. Sudden stops in capital flows, and subsequent deep recessions, are a frequent occurrence in these countries but there is no professional consensus, and little systematic empirical evidence, shedding light on the macroeconomic policy mix most likely to limit output losses during these episodes. To address this issue, we investigate 83 sudden-stop crisis in 66 countries using a baseline empirical model to control for the various determinants of output losses during sudden stops. We measure the marginal effects of policy on output losses, and find strong evidence that monetary tightening (rise in the discount rate or unsterilized rise in international reserves) and discretionary fiscal contraction are significantly correlated with larger output losses following a sudden stop. Fiscal expansion is associated with smaller output losses following a sudden stop, but monetary expansion has no discernable effect. The macroeconomic policy mix associated with the least output loss during a sudden-stop financial crisis is a discretionary fiscal expansion combined with a neutral monetary policy.     

The value of fiscal discipline for oil-exporting countries

The value of fiscal discipline is assessed by analyzing the role of fiscal policy as a transmission mechanism of oil price shocks in oil-exporting small open economies. Fiscal policy is an important propagation channel. Taking policy as given by the data, the model can successfully explain the responses of key macroeconomic variables, but it is unable to explain these responses under counterfactual fiscal frameworks. Interestingly, fiscal policy also seems capable of regulating the size of pass-through. Furthermore, fiscal policies that insulate the economy from oil price shocks seem to be welfare improving over procyclical ones.     

Challenges of Fiscal Policy in Emerging and Developing Economies

This article presents a systematic analysis of the availability and use of fiscal space in emerging and developing economies. We report two major results. First, emerging and developing economies built fiscal space in the run-up to the Great Recession of 2008–2009, which was then used for stimulus. Since then, fiscal space has shrunk and remains narrow as these economies have taken advantage of historically low interest rates. Second, fiscal policy in emerging and developing economies has become countercyclical (or less procyclical), i.e., “graduated,” since the 1980s, as most clearly demonstrated during the Great Recession. The move towards graduation is most pronounced for those economies with greater fiscal space, which suggests that fiscal space matters for a government’s ability to implement countercyclical fiscal policy.     

Strengthening Post‐Crisis Fiscal Credibility: Fiscal Councils on the Rise – A New Dataset

Institutions that aim to constrain policy discretion in order to promote sound fiscal policies are once again at the forefront of the policy debate. Interest in fiscal councils – independent watchdogs active in the public debate – has grown rapidly in recent years. In this paper, we present the first cross‐country dataset summarising key characteristics of fiscal councils among International Monetary Fund members. The data document a surge in the number of fiscal councils since the 2008–09 economic and financial crisis, and also illustrate that well‐designed fiscal councils are associated with stronger fiscal performance and better macro‐economic and budgetary forecasts. Key features of effective fiscal councils include operational independence from politics, the provision or public assessment of budgetary forecasts, a strong presence in the public debate and the monitoring of compliance with fiscal policy rules.     

Fiscal multipliers in the 21st century

Fiscal multipliers appear to vary greatly over time and space. Based on VARs for a large number of countries, we document a strong correlation between wealth inequality and the magnitude of fiscal multipliers. In an attempt to account for this finding, we develop a life-cycle, overlapping-generations economy with uninsurable labor market risk. We calibrate our model to match key characteristics of a number of OECD economies, including the distribution of wages and wealth, social security, taxes, and government debt and study how a fiscal multiplier depends on various country characteristics. We find that the fiscal multiplier is highly sensitive to the fraction of the population who face binding credit constraints and also to the average wealth level in the economy. These findings together help us generate a cross-country pattern of multipliers that is quite similar to that in the data.     

Sustainable development: The impact of political risk,macroeconomic policy uncertainty and ethnic conflict

We examine the impact of political risk, macroeconomic policy uncertainty, and social risk on sustainable development for a panel covering 47 developing economies from 1991 to 2020. We present an augmented green Solow growth model linking policy risk and uncertainty to sustainable development through their interaction with pollution abatement activities. We employ a political risk index to capture the composite impact of risk factors relevant to political rule and regulation, a macroeconomic policy index to evaluate the uncertainty associated with inflation, exchange rate, and fiscal policies and an index of ethnic fractionalization to appreciate social risk. The empirical results confirm that all the risk and uncertainty factors examined exert significant negative short- and long-run impacts on sustainable development. The findings highlight the importance of risk management as a key control policy when designing sustainability policies promoting pollution emissions abatement.     

经济政策不确定性与企业贷款成本

基于大样本微观银行信贷数据,本文研究经济政策不确定性对企业的银行贷款成本的影响。研究发现,经济政策不确定性升高导致企业的银行贷款成本增加,且使得在中小型银行贷款的企业成本增加更多。异质性分析表明,经济政策不确定性升高对受政策因素影响较大的企业如小微企业、私营企业等的银行贷款成本的影响更为明显。进一步,对企业的银行贷款违约风险的研究发现,随着经济政策不确定性升高,企业的银行贷款违约风险反而降低。这表明,经济政策不确定性升高使得银行选择风险评级更低的贷款,符合谨慎性动机。本文研究结论表明,经济政策不确定性升高时,银行“自我保险”动机的增强使得企业的银行贷款成本增加,这在中小型银行中表现得更加明显,同时也更多地转嫁给中小企业。本文为经济政策不确定性对企业投资、宏观经济波动等的研究提供了微观解释机制,并揭示了政府经济政策的一致性、稳定性对维护金融稳定的重要作用。     

中国财政政策乘数效应分析

财政政策是逆周期宏观调控的重要举措,财政政策乘数高低体现了宏观政策的效果,对政府决策具有重要的参考价值.本文基于IS-LM的拓展模型,估计得到2002-2017年间的财政支出乘数在0.58到0.67之间,税收乘数在-0.22到-0.18之间,私人投资乘数在1.16到1.8之间,财政支出乘数较以往研究有较大的下降,沿用传统的刺激需求政策不可持续.通过对财政支出乘数传导机制的进一步研究发现,财政支出对居民消费的拉动作用在一定程度上被政府投资对消费的挤出效应所抵消,政府投资对私人投资的带动效应也受到财政支出挤出效应的抵消,宽松货币政策的配合可以减少财政支出挤出效应.最后基于分析给出相关政策建议.     

Interaction of Government Tiers and Central Banks in a Federation: An Empirical Test

Fiscal rules are necessary to protect monetary policy from the consequences of unsustainable or active fiscal policy for inflation. Monetary unions, such as the Economic and Monetary Union (EMU), require even stronger fiscal rules to avoid free riding by regional fiscal authorities on the common monetary policy. By contrast, in a fiscal federation, the federal government internalises the effect of active regional policies on the overall price level. Federal fiscal policy contributes to price stability either by enforcing fiscal rules or by adjusting its own stance. Following Canzoneri, Cumby and Diba (2001), we test whether federal and regional governments in Germany behave in an active or passive way. We find evidence of a spillover effect of unsustainable policies on other regions. The German federal government offsets the effect on the price level by running passive policies. The Bundesbank's prime objective of price stability is therefore endorsed by fiscal policy. The results have implications for the regulation of fiscal policies in the EMU.
