Explaining ERM realignments: Insights from optimising models of currency crises

This paper attempts to provide empirical evidence on the determinants of the realignments throughout the European exchange rate mechanism (ERM). Motivated by the implications of optimising currency crisis models, we relate the probability of “crises” to a set of macroeconomic fundamentals. By using a conditional binominal logit model we show that regime switches are strongly influenced by movements in industrial production, foreign interest rates, competitiveness and imports as well as in foreign exchange reserves. These findings are consistent with the general propositions of recent currency crises models.     

Volatility spillovers and determinants of contagion: Exchange rate and equity markets during crises

We study the hourly volatility spillover between the equity markets of New York (DJI), London (FTSE 100) and Tokyo (N225) and their exchange rates (USD, EUR, GBP and JPY) for the period of 2001 through 2013 covering the non-crises period, the global financial crisis and the euro debt crisis. First, we find a general increase in spillover between the equity and exchange rate markets during the crisis periods. Second, pure contagion (attributable to irrational investors’ behavior) and fundamental contagion (measured by macroeconomic fundamentals) explains the increased spillover between the FTSE 100, N225 to the DJI during the global financial crisis and from the exchange rate markets to the DJI during the euro debt crisis.     

The more contagion effect on emerging markets: The evidence of DCC-GARCH model

The paper aims to test the existence of financial contagion between foreign exchange markets of several emerging and developed countries during the U.S. subprime crisis. As a result of DCC-GARCH analysis, we find the evidence of contagion during U.S. subprime crisis for most of the developed and emerging countries. Another finding is that emerging markets seem to be the most influenced by the contagion effects during U.S. subprime crisis. Since financial contagion is important for monetary policy, risk measurement, asset pricing and portfolio allocation, the findings of paper may be interest of policy makers, investors and portfolio managers.

Monetary and fiscal coordination in preventing bank failures and financial contagion

This paper uses a theoretical model to analyze the optimal combination of monetary response (lowering of interest rates) and fiscal bailouts in preventing bank failures and financial contagion. I show that the optimal way of rescuing failing banks is to combine the two. This is because lower interest rates reduce the size of the bailout required to rescue failing banks as they reduce the cost for banks to raise and retain deposits. The main result of the paper is that banks are willing to monitor their investments more closely when they anticipate a monetary response in addition to bailouts in case of a banking crisis. Additionally, capital requirements such as the Basel Accords do not always incentivize banks to monitor their investments if there is a potential contagion from unhealthy to healthy banks.     

Financial crises,exchange rate linkages and uncovered interest parity: Evidence from G7 markets

This paper examines the dynamic linkages among major exchange rates during the Global Financial Crisis and Eurozone Sovereign Debt Crisis. We extend the previous literature on volatility spillover linkages among the currencies by taking into account the uncovered interest-rate parity hypothesis for 2004–2015. The results indicate that the Canadian Dollar and Great British Pound were affected mainly by the US Dollar across the two crises due to strong financial and economic ties among the three economies, while the Japanese Yen shows evidence of a safe-haven currency. We also provide evidence of varying vulnerability of currencies to both crises, implying increased portfolio diversification benefits, since holding a portfolio with diverse currencies is less subject to systematic risk. These results show that the policy makers need to adopt a stricter form of monetary policy coordination among central banks, since the different vulnerability of currencies across turbulent periods reveals possible non-cooperative monetary policies.     

Analysis of contagion from the dynamic conditional correlation model with Markov Regime switching

Over the last decades, the transmissions of international financial events have been the subject of many academic studies focused on multivariate volatility models. This study evaluates the financial contagion between stock market returns. The econometric model employed, regime switching dynamic correlation (RSDC). A modification was made in the original RSDC model, the introduction of the GJR-GARCH-N and also GJR-GARCH-t models, on the equation of conditional univariate variances, thus allowing us to capture the asymmetric effects in volatility and also heavy tails. A database was built using series of indices in the United States (S&P500), the United Kingdom (FTSE100), Brazil (IBOVESPA) and South Korea (KOSPI) from 1 February 2003 to 20 September 2012. Throughout this study the methodology is compared with those frequently found in literature, and the model RSDC with two regimes was defined as the most appropriate for the selected sample with t-Student distribution in the disturbances. The adapted RSDC model used in this article can be used to detect contagion – considering the definition of financial contagion from the World Bank called very restrictive – with the help of the empirical exercise.     

Stability periods between financial crises: The role of macroeconomic fundamentals and crises management policies

This study aims to identify which factors explain why some countries enjoy long durations of stability, while others experience crises in shorter intervals. We analyze the duration of stability periods between currency, debt, and banking crises by employing an innovative econometric strategy, the Finite Mixture Model (FMM). Real and financial variables show high predictive power for stability spells between currency crises. Regarding debt crises, the real interest rate is observed to be the best predictor. The time between systemic financial crises appears to be prolonged through government interventions and through IMF program participation, while bank recapitalization has a negative impact.     

Spatial contagion in the subprime crisis context: Adjusted correlation versus local correlation approaches

This paper investigates the influence of the spatial dimension on financial contagion in the subprime crisis based on adjusted and local correlation measures. Daily series of stock indexes of American and Asian countries are used from January 1, 2003, to December 30, 2011. We consider two groups of countries: the first group includes the United States and countries that are geographically close: Brazil, Argentina, Mexico, and Canada. The second group includes countries that are geographically distant from the United States: Hong Kong, India, Australia, Indonesia, Malaysia, South Korea, China, and Singapore. The results show that simple and adjusted correlations are not enough to explain the spatial effect of contagion. Using local correlations and polynomial regressions, the results show the existence of spatial contagion between the United States and all countries in the American region. As for countries that are geographically distant from the United States, we prove the existence of spatial contagion between only some groups of countries (United States/India, United States/Australia, United States/Indonesia, United States/Malaysia, United States/China). These results have international diversification, and within-industry implications.

Time-varying dependence in European equity markets: A contagion and investor sentiment driven analysis

In the light of the global financial crisis and sovereign debt crisis, this paper investigates the dependence patterns in 24 European equity markets from January 5, 2004 to July 1, 2016. We further examine whether these stressful events trigger contagion. Given that investors tend to behave irrationally in turmoil periods, we add to the literature by studying the effect of investor sentiment on markets correlations. Our results reveal heterogeneity in the time-varying dependence and across markets. Contagion is confirmed in turbulent times, a spillover effect from periphery euro area being detected. We find that similar sentiments increase correlations, especially in crises, suggesting that investors’ perceptions are an important channel of moving markets in the same direction. Furthermore, negative sentiments, such as fear or pessimism, amplify the linkages between markets. Our results offer useful insights to policy makers for reacting timely to financial shocks and for designing a more integrated market.     

Income inequality,consumer debt,and prudential regulation: An agent-based approach to study the emergence of crises and financial instability

The paper presents an agent-based model to study the interaction between income inequality and prudential regulations in a macroeconomic framework characterized by consumer debt. Simulation results show that income inequality is detrimental to both macro and financial stability as it leads to higher credit demands, higher unemployment rates, economic volatility, and financial fragility. Besides the importance of consumers' leveraging, deleveraging externalities are found to be equally important for the emergence of crises and financial fragility because of the liquidity risk they entail. Minsky moments are also observed; they are related to consumers' prudential behavior and their beliefs about the macroeconomic conditions. Concerning the policy relevance of our investigation, simulations allow us to highlight that the effectiveness of prudential regulation depends on the phase of the business cycle and that there is not a “one-size-fits-all” regulation. This study emphasizes that regulatory constraints should take into account the features of the economic agents, such as the distribution of income and their willingness to borrow, in addition to the features of the financial sector.     

Evaluating currency crises: the case of the European monetary system

In this paper we examine the nature of currency crises. We ascertain whether the currency crises of the European Monetary System (EMS) were based either on fundamentals, or on self-fulfilling market expectations driven by extrinsic uncertainty. In particular, we extend previous work of Jeanne and Masson (J Int Econ 50:327–350, 2000) regarding the evaluation of currency crisis. We contribute to the existing literature proposing the use of Markov regime-switching with time-varying transition probability model. Our empirical results suggest that the currency crises of the EMS were not due only to market expectations driven by external uncertainty, or ‘sunspots’, but also to fundamental variables that help to explain the behavior of market expectations. We would like to thank Joseph Byrne, James Mitchell, Martin Weale and two anonymous referees for very useful comments and suggestions.     

Interdependence or contagion: A model switching approach with a focus on Latin America

Empirical research analysing contagion has become increasingly fragmented. Different definitions of contagion have resulted in different methods being deployed to analyse financial transmission channels. This paper devises a novel econometric strategy where the nature of interdependencies, magnitude of interdependencies and transmission channels selected for inclusion can change over time. We thus appeal to multiple definitions of contagion, distinguishing between: interdependence, contagion through interdependence and abrupt contagion through changing linkages. Using our approach we analyse different crisis episodes in Latin America. Results generally indicate interdependence not contagion during the currency crises of the 1990s and Argentine crisis of 1998–2002. During the global financial crisis, results indicate abrupt contagion from the US to Argentina and Brazil. Mexico, however, experiences contagion through existing interdependencies with the US. Results also show that macroeconomic and uncertainty channels play a role during different crises not just financial channels. By establishing whether or not different interdependencies and transmission channels are present during different crises our model switching approach provides new insights.     

Financial illness and political virus: the case of contagious crises in the Eurozone

Abstract

This paper investigates the volatility spillover effects from the southern to northern part of the Eurozone during the sovereign debt crisis. Focusing on different phases of the crises, we propose using the dynamic conditional correlation model and the BEKK model to identify possible linkages during the period of 2005–2015. The findings showed that both models behave satisfactorily and are flexible in presenting spillover effects. However, regarding conditional correlations, the asymmetric dynamic conditional correlation model seems to fit better. Additionally, Spain and Italy can significantly damage all strong northern economies, while Greece’s negative shocks are capable of co-moving the French index. Finally, France is the most correlated country within the southern Eurozone.     

Wealth effects on consumption in financial crises: the case of Norway

A dynamic consumption function, where consumption in the long run is determined by households’ disposable income and wealth, has been superior to the Euler equation in explaining the development of Norwegian aggregate consumption over several decades. This period covers the years of financial deregulation in the mid 1980s, the banking crisis around 1990 following the deregulation and the current international financial crisis. In the current version, long run consumption is homogeneous in income and wealth and there is also a significant effect from after-tax real interest rates. A change in the correlation pattern between real interest rates and wealth, which is related to a change in the monetary policy regime, is the reason why both variables need to be included in the long run relationship in order to explain the development over the period 2005q1–2008q4.     

Banks,relative performance,and sequential contagion

We develop a multi-period general equilibrium model of bank deposit, credit, and interim inter-bank loan markets in which banks initially specialize in their choices of debtors, leading to under-diversification, but nevertheless become entwined via inter-bank markets, leading to the fortunes of one bank affecting the profits and default rates of the other in a sequential manner. Lack of (full) diversification among credit risks arises in our model owing to a relative profit argument in each banker’s utility function, which is otherwise risk- and default-averse. We examine its implications for the welfare of depositors and debtors. An erratum to this article can be found at     

Innis Lecture: Environmental crises: past, present, and future

Abstract .  Environmental crises are distinguished by rapid and largely unexpected changes in environmental quality that are difficult if not impossible to reverse. Examples would be major extinctions and significant degradations of an ecosystem. I argue there are three preconditions for crisis: failures in governance, an ecological system exhibiting a tipping point, and an economy/environment interaction with positive feedbacks. I develop a simple model to illustrate how a crisis may arise, and draw on our knowledge of past and present crises to highlight the mechanisms involved. I then speculate as to whether climate change is indeed a crisis in the making.     

Fiscal crises,decentralization, and indiscipline

How does fiscal decentralization influence fiscal discipline and the probability of a fiscal crisis? Discrete choice analysis used with panel data reveals that crisis probability is associated positively with spending decentralization and negatively with vertical fiscal imbalance. These effects are prevalent in countries with a higher degree of tax revenue decentralization, while a stronger rule of law mitigates such adverse decentralization effects. The findings imply that reduced risk sharing against local shocks under tax revenue decentralization destabilizes the sustainability of a nation's fiscal system. Therefore, policymakers should be cognizant of the undesirable impacts of decentralization on fiscal crisis and indiscipline.
