Debt Crises and Risk‐Sharing: The Role of Markets versus Sovereigns

Using a variance decomposition of shocks to gross domestic product (GDP), we quantify the role of international factor income, international transfers, and saving in achieving risk‐sharing during the recent European crisis. We focus on the subperiods 1990–2007, 2008–2009, and 2010 and consider separately the European countries hit by the sovereign debt crisis in 2010. We decompose risk‐sharing from saving into contributions from government and private saving, and show that fiscal austerity programs played an important role in hindering risk‐sharing during the sovereign debt crisis.     

Sovereign debt, structural adjustment, and conditionality

The lack of a proper enforcement mechanism for sovereign debt generates a commitment failure. As a result, a sovereign may seek to improve its position in debt renegotiations and thus evade its debt obligations by reducing exports. Conditionality seeks to provide a solution to the incentive problem by addressing the commitment failure. Formalizing this argument, we show that conditionality helps the repayment of sovereign debt. In certain circumstances, it can eliminate debt overhang, especially when it is coupled with concessionary lending of sufficient magnitude. It is, however, unable to restore first best. When it is anticipated by lenders, conditionality may get international financial institutions and sovereign debtors into a trap where the debt overhang persist, debt rescheduling takes place periodically, and conditionality continues indefinitely.

Credit risk and sustainable debt: a model and estimations of why the Euro is stable in the long-run

Sustainable debt has become the key issue in rating of private as well as sovereign debtors. The problem of how to estimate sustainable debt has also been at the center of the debate over the Asian 1997–1998 financial crisis. If the external value of the currency depends on the external debt of a country, it is necessary to estimate the creditworthiness of the country. This paper studies credit risk and sustainable debt in the context of a dynamic model. For a dynamic growth model with an additional equation for the evolution of debt, we demonstrate of how to compute sustainable debt and creditworthiness. The model is estimated by employing time series data for the core countries of the Euro-area. The computations show that the Euro-area has large external assets. Using time series methods, the sustainability of external debt (assets) is estimated for those core countries of the Euro-area. Those estimations show that the Euro will be a stable currency in the long-run.     

Risks of Latin America sovereign debts before and after the financial crisis

We investigate the financial determinants of the return and volatility of sovereign CDS spread from six major Latin American countries before and after the bankruptcy of Lehman Brothers. Other than CBOE VIX index, we also find that global factors including US Baa–Aaa default yield, TED spread and US Treasury rate all contribute to the changes in these sovereign CDS spread. Although global risk aversion (VIX) is a significant determinant of sovereign debt spread, in the years after the crisis, the emphasis has shifted towards short-term refinancing risk (TED). Furthermore, the risk of Greek sovereign debt crisis also transmitted Latin American CDS spreads immediately, but only in the post-Lehman sub-period. These findings provide implications for international bonds and credit derivatives trading strategies.     

On the Term Structure of Sovereign-Debt Contracts*

This paper studies the term structure of a repudiation-proof debt contract encompassing many sequentially scheduled short-term loans in a principal-agent (lender-sovereign borrower) framework. the extension of each loan is conditional on the full repayment of the previous loans in due maturity. Both direct sanctions and loss of access to the international credit market are present as debt-repudiation costs. It is shown that the proposed repudiation-proof composite contract exhibiting decreasing loan sizes and increasing maturities is better for coping with the enforcement problems that characterize sovereign lending.     

中国主权资产负债表及其风险评估(下)

2000——2010年,中国的国民资产负债表呈快速扩张之势。对外资产、基础设施以及房地产资产迅速积累,构成资产扩张的主导因素。这记载了出口导向发展战略之下中国工业化与城镇化加速发展的历史进程。在负债方,各级政府以及国有企业的负债以高于私人部门的增长率扩张。这凸显了政府主导经济活动的体制特征。对主权资产负债表的风险评估表明:(1)总体上,中国主权净值为正,因而,在相当一段时间内,发生主权债务危机的概率极低;(2)近期的风险点主要体现在房地产信贷与地方债务上,而中国的长期风险则更多集中在对外资产负债表、企业债务与社保欠账上。这些风险大都是或有负债风险,且与过去的发展方式密切相关;(3)主权债务动态的模拟进一步揭示出维持经济增长率与利率之差对于化解债务风险的重要性。因此,转变经济发展方式,保持经济可持续增长,是应对主权债务风险的根本途径。     

Sovereign risk and deposit dynamics: evidence from Europe

The unprecedented expansion of sovereign balance sheets since the beginning of the global crisis has given a new meaning to the term sovereign risk. Developments in Europe since early 2010 revealed new challenges for the functioning of private banks in an environment of heightened sovereign risk and may have contributed to deleveraging. The article uses an innovative way of measuring the perception of sovereign risk and its impact. Using an extension of a common market discipline framework, it shows that exposure to sovereign risk may have limited the ability of banks in Europe to collect deposits. Potential identification issues between deposits and bank efficiency are controlled by using data envelopment analysis (DEA). The results are robust to inclusion of conventional measures of bank performance and the sector-wide holdings of foreign sovereign debt.     

Assessing Recent Determinants of Borrowing Costs in Sub‐Saharan Africa

This study explores macroeconomic implications of the sovereign bond rush that has been taking place in sub‐Saharan Africa since 2006. The focus is on the sub‐Saharan sovereign bond yields as proxies for the region's ability to raise new funds on international markets. Despite the subcontinent's tour‐de‐force entrance to the international bond market, this paper reveals that recent (since early 2000s) borrowing in foreign currency is not without macroeconomic risk. Empirically this paper finds that sovereign bond yields are significantly influenced by global volatility, commodity prices and global liquidity—all factors that are out of the control of the sub‐Saharan economies in question. These findings suggest that portfolio repositioning by institutional investors prompted by improved growth prospects and implicit monetary policy tightening in the advanced economies or heightened risk perceptions, are likely to result in increased borrowing costs for the sub‐Saharan bond issuers and affect their ability to raise funds in international markets. Furthermore, a change in borrowing costs might lead to higher debt‐service costs and policy uncertainty, which in turn could lead to suboptimal investment levels and, ultimately, hinder economic development.     

Sovereign Debt Capacity and the Distribution of Domestic Wealth: A Common Agency Model*

This paper proposes a stylized two‐period, two‐country model illustrating the role of distribution of domestic wealth in determining a country's level of access to international lending. We model sovereign debt redemption policy in a common agency framework. Within this framework, policy is the outcome of the interaction between government and local and foreign interest groups with conflicting preferences on debt repayment. Our main result is that in full lobby competition, when all interests are represented, the only equilibrium solution is repudiation and the consequent inability of government to access international capital markets. Conversely, when the ability to lobby depends on wealth, governments can access international credit up to a given maximum external debt capacity, determined by the skew in the distribution of domestic wealth.

Sovereign debt spread and default in a model with self-fulfilling prophecies and asymmetric information

The euro area sovereign debt crisis has renewed interest in government credibility and the risk of default. Recent empirical evidence has shown that the sharp increase in government bond yields cannot be attributed entirely to changes in macroeconomic fundamentals. Contagion effects can occur, and self-fulfilling speculation may arise. In this paper, we develop a theoretical model in the spirit of the second-generation currency crisis models developed by Obstfled (1996). The model describes a strategic game between governments and private investors. Euro area countries face a trade-off as governments may either commit to and implement restrictive fiscal policies or default on debt. The commitment strategy may not be optimal if the fundamentals deteriorate. The policy maker lose part of their credibility, and governments are forced to default. In addition, we introduce uncertainty about the cost of default in the model, which is then able to account for a greater variety of equilibrium. Thus, when the evaluation of the cost of default is asymmetric, prophecies are not always realized and default does not occur. Simulations of the model then show that it offers insights, and can help to account for the situations of Greece and Italy during the sovereign debt crisis.     

Can fiscal rules improve financial market access for developing countries?

A number of countries have introduced fiscal rules to deter fiscal profligacy, enhance the credibility of fiscal policy, and reduce borrowing costs. In this paper, we examine the outcome of fiscal rules in terms of improving financial market access for developing countries. We use entropy balancing and various propensity score matching. We find that the adoption of fiscal rules reduces sovereign bond spreads and increases sovereign debt ratings for a sample of 36 developing countries, which are part of the JP Morgan Emerging Markets Bond Index Global (EMBIG), for the period 1993-2014. We explain this finding by the effect of fiscal rules on the credibility of a country's fiscal policy: more credible governments are rewarded in the international financial markets by low sovereign bond spreads and high sovereign debt ratings. These results are robust to a wide set of alternative specifications. We also show that this favorable effect is sensitive to several country structural characteristics. Our findings confirm that the adoption and sound implementation of fiscal rules is an instrument for policy makers to improve developing countries’ financial market access.     

中国主权资产负债表及其风险评估(上)

本文基于国民资产负债表的理论框架,运用现有数据并通过必要的估算,初步编制了2000—2010年的中国主权资产负债表。结果显示,中国各年主权资产净额均为正值且呈上升趋势。这表明,中国政府拥有足够的主权资产来覆盖其主权负债。因此,在不短的时期内,中国发生主权债务危机的可能性极低。对总债务水平与全社会杠杆率(即总债务/GDP)的分析显示:中国的全社会杠杆率虽高于金砖国家,但远低于所有的发达经济体,总体上处在温和、可控的阶段。但是,近年来该杠杆率的提高速度很快,须引起关注。分部门的分析显示:企业负债率(占GDP比重)很高,构成中国资产负债表的显著特色。2010年,该负债率已逾100%,超过OECD国家90%的阈值,值得高度警惕。     

Domestic versus External Borrowing and Fiscal Policy in Emerging Markets

This paper presents a model of an emerging market sovereign that can selectively default on its domestic or external creditors. The two classes of creditors have different ways of punishing the government in the event of default, which in turn creates a differential in the sovereign's incentives to default on its domestic versus foreign creditors. We explore the extent to which the possibility of differential treatment of creditors affects the composition of debt. We find that a country characterized by volatile output, sovereign risk, and costly tax collection will want to borrow in domestic as well as in international markets.     

The sovereign spread in Asian emerging economies: The significance of external versus internal factors

This paper investigates the dynamic relations between external factors, domestic macroeconomic factors with sovereign spreads, debt to GDP ratio, etc. in Asian emerging countries. First, we develop a theoretical model that determines the equilibrium debt level, probability of default and sovereign spread and draw empirical implications. We then employ a Structural Vector Autoregression (SVAR) model to investigate empirically how the spread of sovereign debt is influenced over time by both external and domestic factors. The empirical results show that variations in sovereign spreads are mainly driven by external shocks, with the term structure of US interest rate and the global risk aversion having the most important role. The findings also indicate that shocks from the US have a direct effect on sovereign spread and an indirect effect via domestic macroeconomic fundamentals. Finally, the evidence produced validates the presence of some response patterns of sovereign spread to the external shocks.     

Business Cycle Synchronization in the Enlarged EU: The Role of Bilateral Trade and FDI

The aim of this paper is to investigate the determinants of business cycle (BC) synchronization across 21 (old and new) countries of the enlarged European Union (EU). It utilizes international data to evaluate the linkages among bilateral trade in goods, bilateral foreign direct investment (FDI) flows and BC co‐movements. The paper contributes to the current literature by examining the relationship using the latest available data (sample range: 1998–2011), and thus taking into account the European sovereign debt crisis period. It also examines the role of FDI, which though increasingly important in the flows of international production factors, is currently neglected by the literature. Preliminary results show that FDI has no direct effect on BC synchronization while international trade helps to synchronize BCs but only before the recent financial crisis (pre‐2008) and only for the traditional EU countries.     

Competitive equilibria with limited enforcement

We show how to decentralize constrained efficient allocations that arise from enforcement constraints between sovereign nations. In a pure exchange economy these allocations can be decentralized with private agents acting competitively and taking as given government default decisions on foreign debt. In an economy with capital these allocations can be decentralized if the government can tax capital income as well as default on foreign debt. The tax on capital income is needed to make private agents internalize a subtle externality. The decisions of the government can arise as an equilibrium of a dynamic game between governments.     

Where states and markets meet: the financialisation of sovereign debt management

Financial markets play an indispensable role in the management of sovereign debt, that is, the mechanics of how and from whom governments borrow. This paper suggests a novel, two-dimensional concept to measure the financialisation of sovereign debt management (SDM): (1) the reliance on financial markets as a governance mechanism and (2) the adoption of a sense-making framework grounded in financial economics. We split this concept into nine indicators and apply it to data from 23 OECD countries between 1980 and 2010. Our analysis illustrates the predominant commonalities across countries, but at the same time, country-specific differences. We interpret them as two sides of the same coin in the light of an overarching trend of increasing alignment to financial markets. This article is not only one of the first cross-national as well as longitudinal studies of the dynamics in SDM; it also reveals that the relationship between finance and governments in the SDM is by no means one-sided.     

Increase in home bias in the Eurozone debt crisis: The role of domestic shocks

One of the most striking consequences of the recent episode of sovereign debt market stress in the Eurozone has been the increase in the share of public debt held by the domestic sector in fragile economies. However, the causes and potential consequences of this increase were only given scarce attention in the literature on the Euro area sovereign debt crisis. In order to fill this gap, we first determine the shocks that impact the variation in the share of sovereign debt held at home in an SVAR model on a sample of Eurozone countries between 2002 and 2014, distinguishing between external and domestic shocks. Thanks to several alternative tests, we show that home bias in sovereign debt responds positively to country-specific fundamentals and expectation shocks but we find no evidence that the increase in home bias is destabilizing per se in the short-run. Second, a stylized theoretical model backed by the empirical results predicts that the consequences for sovereign debt crisis depend on the relative impact of domestic initial destabilizing shocks and increased home bias. The analysis suggests that an increase in home bias in times of sovereign debt stress, despite reflecting deteriorating fiscal conditions, may make default less likely.
