欧洲主权债务危机的发展与应对之策

受近期希腊债务违约风险上升、欧债危机向核心国蔓延、欧洲银行业融资缺口扩大等负面因素冲击,欧洲金融市场遭遇大幅动荡。文章指出,在短期内,防止希腊债务违约是遏制欧债危机进一步蔓延、防范债务危机与银行危机并发的关键;长期而言,欧元及欧盟运作机制的改革将不可避免,完善退出机制将是欧元区长期稳定运作的基石。     

Price effects of sovereign debt auctions in the euro-zone: The role of the crisis

We show that new public debt issues cause an auction cycle for Italian secondary-market debt, but not for German debt. The cycle is mainly observed for the crisis period since mid-2007 and is larger when the crisis, as measured by yield volatility and CDS spreads of primary dealers, is more intense. Volatility seems to be the main driving factor. The cycle is also present in secondary-market series with maturities close to the auctioned series. Our findings are consistent with the theory of primary dealers’ limited risk-bearing capacity. There is also weak evidence of spill-overs from foreign auctions to domestic markets.     

Realized volatility spillovers between US spot and futures during ECB news: Evidence from the European sovereign debt crisis

We study the simultaneity impact of the European Central Bank news on the daily realized volatility transmission mechanism (spillovers) among various US spot and futures markets. To this end, we apply a bias-corrected vector autoregressive model via Wild bootstrap simulation. We use minute-by-minute intraday data to construct daily realized volatility. We consider 429 news form the ECB as important events employing two major classifications, namely, a country classification with the highest total number of days related ECB news and a type of ECB news classification. We find that investors in futures markets react more vigorously and mainly for the ECB news that is associated with the group of EMU member states applied structural reforms. Yet, more importantly, we show that the US stock markets response heterogeneously to the ECB news, as we find key disagreements in the reactions both across the US markets and the types of ECB news studied. Such evidence is consistent with the explanation of the differential interpretation of information among market participants. From a practical point of view, we suggest that investors in the US spot market can effectively use two or more futures contracts to minimize their exposure to volatility risk associated with that news.     

Do institutions prevent contagion in financial markets? Evidence from the European debt crisis

ABSTRACT

The recent European Sovereign Debt Crisis brought in attention a number of structural problems in the European Union. Part of the effort to correct these problems in the countries that were mostly affected by the crisis were a number of policy responses from the European Union, the European Central Bank, the International Monetary Fund and the Local Governments. In this study, we attempt to assess the success of these responses to constrain the contagion of the crisis from the banking sector to the real economy sectors of the Eurozone countries. Our results show that policy announcements from the EU/ECB/IMF affect the transmission of shocks generated in the banking sector to the market. Moreover, policy responses of the national governments also seem to play a role in the contagion of the crisis.     

An asymmetric dynamic conditional correlation analysis of linkages of European financial institutions during the Greek sovereign debt crisis

This article employs the asymmetric dynamic conditional correlation (DCC) model to assess impacts of the recent sovereign debt crisis on the time-varying correlations of five European financial institutions holding large amounts of Greek sovereign bonds (National Bank of Greece, BNP Paribas, Dexia, Generali, and Commerzbank). Contrary to the results of preceding studies, we find significant increases in the correlations between several combinations of the financial institutions’ stock returns after the inception of the sovereign debt crisis, indicating contagion effects. Moreover, our findings show that the parameter of the standardized negative residuals is statistically significant in the case of DCC estimates between two specific institutions. This suggests that the conditional correlation of stock returns between the two institutions is more significantly influenced by negative shocks than by positive innovations to return.     

The systemic risk of European banks during the financial and sovereign debt crises

European banks became a source of risk to global financial markets during the financial crisis and attention to the European banking sector increased during the sovereign debt crisis. To measure the systemic risk of European banks, we calculate a distress insurance premium (DIP), which integrates the characteristics of bank size, probability of default, and correlation. Based on this measure, the systemic risk of European banks reached its height in late 2011 around €500 billion. We find that this was largely due to sovereign default risk. The DIP methodology is also used to measure the systemic contribution of individual banks. This approach identifies the large systemically important European banks, but Italian and Spanish banks as a group notably increased in systemic importance during the sample period. Bank-specific fundamentals like capital-asset ratios predict the one-year-ahead systemic risk contributions.     

Determinants of Capital Structure in Emerging European Economies: Evidence from Slovenian Firms

Although empirical research has shown that some capital structure differences can be explained by modern capital structure theory in mature market economies, the forces behind capital structure decisions in emerging European economies remain a puzzle. We assume that, in these countries, the change in economic system, and therefore corporate governance, has been only gradual; other forces must be at work when firms decide on their capital structures compared to those of mature market economies. After identifying possible relevant factors in Slovenian firms, we show that throughout the period from 1999 to 2006, these factors explained the greatest part of capital structure differences. However, the explanatory power of the proposed factors is changing, which implies changing corporate governance and financial behavior of Slovenian firms during transition.     

Corporate cash holdings: Evidence from Switzerland

This paper investigates the determinants of cash holdings for a comprehensive sample of Swiss non-financial firms between 1995 and 2004. The median Swiss firm holds almost twice as much cash and cash equivalents as the median US or UK firm. Our results indicate that asset tangibility and firm size are both negatively related to corporate cash holdings, and that there is a non-linear relationship between the leverage ratio and liquidity. Dividend payments and operating cash flows are positively related to cash reserves, but we cannot detect a significant relationship between growth opportunities and cash holdings. Most of these empirical findings, but not all of them, can be explained by the transaction costs motive and/or the precautionary motive. Analyzing the corporate governance structures of Swiss firms, we document a non-linear relationship between managerial ownership and cash holdings, indicating an incentive alignment effect and an opposing effect related to increasing risk aversion. Finally, our results suggest that firms in which the CEO simultaneously serves as the COB hold significantly more cash.

Political costs and corporate tax avoidance: Evidence from sin firms

The products and services of firms operating in sin industries (alcohol, tobacco, gambling, and firearms) run contrary to social norms and can produce significant negative externalities for society. As such, we expect that sin firms are at greater risk of incurring political costs in the form of additional regulation, higher excise taxes, or capital market intervention if they come under scrutiny for their income tax avoidance practices. Because of the nature of their products, regulators and policymakers are likely to face less pushback on new regulations or taxes on these firms. Sin firms start with a lower ability to influence the political process than firms in non-sin industries. Consequently, we hypothesize and find that sin firms exhibit less tax avoidance than non-sin firms, particularly through uncertain and more risky tax avoidance strategies. The negative relationship between the status of sin firms and tax avoidance is less pronounced in firms that accumulate political capital via intensive lobbying activities. Exploiting changes in partisan control of the Congress and White House, difference-in-differences tests show that firearm firms engage in less (more) tax avoidance when the Democrats (Republican) control both the Congress and White House. Overall, we conclude that political costs play an important role in corporate tax avoidance decisions.     

The extreme risk connectedness of the new financial system: European evidence

The paper empirically analyses the tail risk connectedness between FinTech and the banking sector in the European context over 2015–2022. For this purpose, we use the Tail-Event driven NETworks (TENET) risk model, i.e., we can capture the behaviour of extreme (negative and positive) risk spillover within the financial system. The results highlight how most tail risk spillovers are from banks to FinTech firms. Also, the findings suggest that the spillovers of cross-sector tail risk are more significant in downside (bearish) risk conditions than in upside (bullish) one. We find evidence of an asymmetric effect of extreme risk spillover to the real economy. Finally, we evaluate the monetary policy’s impact on extreme risk. Our findings highlight the importance of closer monitoring risk spillover between FinTech institutions and the European banking system to maintain financial stability.     

European foreign exchange market efficiency: Evidence based on crisis and noncrisis periods

This study investigates the impact on foreign exchange market efficiency of the 1992 European financial market crisis by studying precrisis, crisis, and postcrisis periods. Long-term relationships among European currency values are identified during the three periods, although the relationships are not stable during the precrisis and the postcrisis periods. These results may be due to one or more of the following: (1) market inefficiency, (2) a risk premium, or (3) common policy guidelines for European monetary system (EMS) members. Evidence of market inefficiency is strong. Forecasting results demonstrate better performance by an error correction model (ECM) than by a random walk model (RWM) for the British pound and German mark, while results for the French franc and Italian lira are mixed. Dominance tests using Granger causality indicate only weak German mark dominance both in the short and long run.     

Securitization and distressed loan renegotiation: Evidence from the subprime mortgage crisis

We examine whether securitization impacts renegotiation decisions of loan servicers, focusing on their decision to foreclose a delinquent loan. Conditional on a loan becoming seriously delinquent, we find a significantly lower foreclosure rate associated with bank-held loans when compared to similar securitized loans: across various specifications and origination vintages, the foreclosure rate of delinquent bank-held loans is 3% to 7% lower in absolute terms (13% to 32% in relative terms). There is a substantial heterogeneity in these effects with large effects among borrowers with better credit quality and small effects among lower quality borrowers. A quasi-experiment that exploits a plausibly exogenous variation in securitization status of a delinquent loan confirms these results.     

Political uncertainty and a firm's credit risk: Evidence from the international CDS market

Using a large sample of firms with single-name credit default swap (CDS) contracts in 30 countries, we document the evidence that political uncertainty, proxied by national election dummy, is positively related to firm-level credit risk. Specifically, this positive relation is more pronounced for the firms that have no political connection or poor international diversification, and in the countries with higher political uncertainty and lower investor protections. Further, by using a difference-in-differences approach, we find evidence to support idiosyncratic volatility and debt rollover channels through which political uncertainty affects the credit risk of individual firm.     

National culture and bank performance: Evidence from the recent financial crisis

We examine whether the prevailing national culture has been material in determining bank performance during the recent financial crisis. In this paper, we focus on three particular national culture dimensions: uncertainty avoidance, individualism/collectivism, and power distance. We expect banks from high uncertainty avoidance and power distance societies to perform relatively better during the recent financial crisis. On the other hand, banks in individualistic (collectivist) societies are likely to perform worse (better) during the crisis. Using an international sample of 3438 banks from 48 countries, we find support for our main conjectures. Specifically, we establish that uncertainty avoidance, collectivism, and power distance have a first order impact on bank performance during the crisis. Our results are robust to a battery of additional checks, including additional variables, alternative samples, and correcting for potential endogeneity.     

Dynamic debt runs and financial fragility: Evidence from the 2007 ABCP crisis

We use the 2007 asset-backed commercial paper (ABCP) crisis as a laboratory to study the determinants of debt runs. Our model features dilution risk: maturing short-term lenders demand higher yields in compensation for being diluted by future lenders, making runs more likely. The model explains the observed tenfold increase in yield spreads leading to runs and the positive relation between yield spreads and future runs. Results from structural estimation show that runs are very sensitive to leverage, asset values, and asset liquidity, but less sensitive to the degree of maturity mismatch, the strength of guarantees, and asset volatility.     

Multinational Diversification and Corporate Performance: Evidence from European Firms

We investigate the empirical relationship between accounting based measures of performance and the degree of multinational diversification for a set of European chemical industry firms. We find that for these firms, the degree of multinational diversification is strongly related to superior financial performance. The results hold for each of the three sample years. The findings suggest that multinational firms outperform purely domestic and exporting firms. The results provide strong support for gains from multinational diversification. The results indicate that while greater European unification may have eroded potential benefits of exploiting international capital and product market imperfections, the benefits of firm specific economies of scope and scale as well as managerial and financial synergies are still realised through exports.     

Financial stress,sovereign debt and economic activity in industrialized countries: Evidence from dynamic threshold regressions

We analyze how the impact of a change in the sovereign debt-to-GDP ratio on economic growth depends on the level of debt, the stress level on the financial market and the membership in a monetary union. A dynamic growth model is put forward demonstrating that debt affects macroeconomic activity in a non-linear manner due to amplifications from the financial sector. Employing dynamic country-specific and dynamic panel threshold regression methods, we study the non-linear relation between the growth rate and the debt-to-GDP ratio using quarterly data for sixteen industrialized countries for the period 1981Q1-2013Q2. We find that the debt-to-GDP ratio has impaired economic growth primarily during times of high financial stress and only for countries of the European Monetary Union and not for the stand-alone countries in our sample. A high debt-to-GDP ratio by itself does not seem to necessarily negatively affect growth if financial markets are calm.     

Bank performance and convergence during the financial crisis: Evidence from the ‘old’ European Union and Eurozone

This paper investigates the process of banking integration in the EU15 countries and the Eurozone by testing for convergence in bank efficiency among commercial banks. We use a two-step approach: First we estimate efficiency by applying an innovative methodological approach that treats banks’ non-performing loans as an undesirable output. Second, we apply the Phillips and Sul (2007) panel convergence methodology to assess the convergence process in European banking. Our results indicate an overall decline in efficiency and no evidence of group convergence following the financial crisis. However, we find the presence of club formation with typically weak convergence. The heterogeneity displayed by the transition parameters for the individual countries and the notable decrease in competition levels post 2008 highlight the impact of the financial crisis on the integration process.     

PCAOB international inspection access and debt contracting: Evidence from American Depositary Receipt firms

We examine whether the Public Company Accounting Oversight Board’s (PCAOB’s) international inspection access affects the usage of accounting-based debt covenants in bank loan contracts of American Depositary Receipt (ADR) borrowers. We show that there is an increase in the use of financial covenants in debt contracts after the auditor of an ADR borrower becomes subject to PCAOB inspections. We also document that lenders increase the usage of financial covenants only in loans to ADR borrowers domiciled in countries with weak home country intuitions, and the increase is more pronounced for ADR borrowers from countries without a local auditor regulatory oversight body. These findings suggest that PCAOB regulatory oversight enhances the perceived credibility of accounting numbers for debt contracting and serves as a substitute for the weak monitoring of auditors for ADR borrowers domiciled in countries with weak country institutions.     

Threat of entry and debt maturity: Evidence from airlines

I explore the effect of the threat posed by low-cost competitors on debt structure in the airline industry. I use the route network expansion of low-cost airlines to identify routes where the probability of future entry increases dramatically. I find that when a large portion of their market is threatened, incumbents significantly increase debt maturity before entry occurs. Overall, the main findings suggest that airlines respond to entry threats trading off the benefits of short-term financing for lower rollover risk. The results are consistent with models in which firms set their optimal debt structure in the presence of costly rollover failure.
