Most discussions of the Greek debt overhang have focussed on the implications for Greece. We show that when additional funds released to the debtor (Greece), via debt restructuring, are used efficiently in pursuit of a practicable business plan, then both debtor and creditor can benefit. We examine a dynamic two country model calibrated to Greek and German economies and support two-steady states, one with endogenous default and one without, depending on creditors’ expectations. In the default steady state, debt forgiveness lowers the volatility of both German and Greek consumption whereas demanding higher recovery rates has the opposite effect. In a second order approximation of the model, conditional welfare analysis shows that a policy of immediate leniency followed by harsher terms as the economy grows is beneficial to both creditors and debtors.

Theories of loan contracting in the presence of asymmetric information highlight the key role of collateral in mitigating against credit rationing. However, theory also allows for the use of collateral by ‘bad’ borrowers in order to receive better loan contract offers. In this study, we explore the extent to which collateral can affect the incidence of absolute loan denial and partial rationing associated with smaller loans than requested being offered. Using data from a large survey of UK small- and-medium enterprises, we find significant evidence on the negative effect of collateral. Our results also reveal important distinction between lines of credit and term loans, where the presence of collateral is associated with 3 % less term loan approved compared to overdraft. We argue that even the request (or offer) of collateral for a term loan indicates that either the bank or the firm believes it is a risky bet.

We find evidence consistent with risk mispricing in the eurozone sovereign credit market for crisis and non-crisis countries alike, using a novel variable of sovereign debt expansion (DE) that we construct. DE predicts increased default probability, but panel regressions from 2002 to 2017 show a negative association with risk premia, even when controlling for risk appetite and the known determinants of sovereign risk premia. As expected, the negative association was only briefly interrupted by the 2010 Deauville Summit, but it resumed by the onset of the 2011 eurozone crisis. The introduction of quantitative easing in 2015 mutes the negative association, raising the concern of what will happen once quantitative easing ends. Our finding is robust to several model specifications.

The recent financial crisis has clearly shown that the relationship between bank internationalization and risk is complex. Multinational banks can benefit from portfolio diversification, reducing their overall riskiness, but this effect can be offset by incentives going in the opposite direction, leading them to take on excessive risks. Since both effects are grounded on solid theoretical arguments, the answer of what is the actual relationship between bank internationalization and risk is left to the empirical analysis. In this paper, we study such relationship in the period leading to the financial crisis of 2007–2008. For a sample of 384 listed banks from 56 countries, we calculate two measures of risk for the period from 2001 to 2007 – the expected default frequency (EDF), a market-based and forward-looking indicator, and the Z-score, a balance-sheet-based and backward-looking measure – and relate them to the degree of banks’ internationalization. We find robust evidence that international diversification increases bank risk.

We derive the default cascade model and the fire-sale spillover model in a unified interdependent framework. The interactions among banks include not only direct cross-holding, but also indirect dependency by holding mutual assets outside the banking system. Using data extracted from the European Banking Authority, we present the interdependency network composed of 48 banks and 21 asset classes. For the robustness, we employ three methods, called Anan, Hała and Maxe, to reconstruct the asset/liability cross-holding network. Then we combine the external portfolio holdings of each bank to compute the interdependency matrix. The interdependency network is much denser than the direct cross-holding network, showing the complex latent interaction among banks. Finally, we perform macroprudential stress tests for the European banking system, using the adverse scenario in EBA stress test as the initial shock. For different reconstructed networks, we illustrate the hierarchical cascades and show that the failure hierarchies are roughly the same except for a few banks, reflecting the overlapping portfolio holding accounts for the majority of defaults. We also calculate systemic vulnerability and individual vulnerability, which provide important information for supervision and relevant management actions.

Previous work suggests that the charter value hypothesis is theoretically grounded and empirically supported, but not universally. Accordingly, this paper aims to perform an analysis of the relations between charter value, risk taking, and supervision, taking into account the relations’ complexity. Specifically, using the CAMELS rating system as a general framework for supervision, we study how charter value relates to risk and supervision by means of classification and regression tree analysis. The sample covers the period 2005–2016 and consists of listed banks in countries that were members of the Eurozone when it came into existence, along with Greece. To evaluate the crisis consequences, we also separately analyze four subperiods and countries that required financial aid from third parties and those that did not so, along with large and small banks. Our results reflect the complexity of the relations between charter value, supervision, and risk. Indeed, supervision and charter value seem aligned regarding only some types of risk.

We examine the influence of both organizational and geographical religiosity, as important ethical parameters moderating a bank’s decision to securitize their assets. The study employs a unique database of banks located within countries marked by high (low) religious adherence. Our results provide evidence that different measures of religiosity affect a bank’s decision to securitize their assets: Banks located in countries with high religious adherence are less likely to engage with securitization compared to banks in countries with lower religiosity, while Islamic banks have a higher likelihood of embarking on a highly monitored model of asset securitization in contrast to conventional banks. When examining the motives underlying a bank’s decision to securitize assets, there is strong evidence that Islamic banks securitize their assets to improve their portfolio diversification, financial performance, and regulatory compliance. This study highlights the importance of considering informal ethical mechanisms, such as religiosity, at both the country and firm levels, when studying bank risk-taking and trading decisions, especially in countries with dual banking systems.
