The impact of VIX on China’s financial market: A new perspective based on high-dimensional and time-varying methods

Based on the new perspective of high-dimensional and time-varying methods, this paper analyzes the contagion effects of US financial market volatility on China’s nine financial sub-markets. The results show evidence of non-linear Granger causality from the US financial volatility (VIX) to the China’s financial markets. Increased US financial volatility has a negative next-day impact on the stock, bond, fund, interest rate, foreign exchange, industrial product and agricultural product markets, and a positive next-day impact on the gold and real estate markets. US financial volatility has the greatest impact on industrial product market, following by stock, agricultural product, fund, real estate, bond, gold, foreign exchange, and interest rates. Major risk events such as the global financial crisis can cause an enhanced contagion effect of US financial volatility to China's financial markets. This paper supports the achievements of China's actions to prevent and resolve major financial risks in the period of the COVID-19 epidemic.     

Financial crises and economic growth

This paper constructs a simple yet robust model of financial crises and economic growth where financial markets affect real economic activity. Financial markets increase real output by facilitating investment through the borrowing/lending of capital. However, the borrowing of capital is risky due to randomness in the firms’ production. Financial crises occur when output and liquid capital are insufficient to meet required loan payments and systemic defaults occur. In this model, a financial crisis caused by systemic defaults can shift the economy from an equilibrium with positive borrowing/lending to an equilibrium with no borrowing/lending. In this no-lending equilibrium, neither traditional fiscal or monetary policy tools are effective in increasing output. Fiscal and monetary policy can only increase the likelihood of the equilibrium evolving to a borrowing/lending equilibrium.     

The impact of ADR activity on stock market liquidity: Evidence from Latin America

This paper examines the impact of ADR activity on liquidity of four major Latin American stock markets. We construct a measure of ADR activity in U.S. markets for a sample of ADRs trading during January 2003–December 2010, which is subsequent to the financial liberalization episodes and currency crises that shocked emerging markets in the 1990s. The sample lists 164 depositary receipt programs (Levels I, II, and III): 16 from Argentina, 81 from Brazil, 19 from Chile, and 48 from Mexico. Using System GMM methods to handle the potential effects from stock market development on economic growth and ADR issuance, we find that higher ADR turnover in U.S. markets has positive effects on domestic market turnover, particularly for issuance of exchange-listed (Levels II and III) ADRs. This positive relationship is not a statistical artifact created by the global financial crisis of 2008.     

Stock market linkages and financial contagion: A cobreaking analysis

Financial crises have shown that dramatic movements in one financial market can have a powerful impact on other markets. This paper proposes to use cobreaking to model comovements between stock markets during crises and to test for contagion. We find evidence of cobreaking between developed stock markets. In emerging stock markets, the evidence of cobreaking is mainly due to the non-financial event of the World Trade Center terrorist attacks in 2001. We find evidence of short-term linkages during times of crisis but not contagion. These short-term linkages have important implications for investors, risk managers and regulators.

Financial contagion vulnerability and resistance: A comparison of European stock markets

This paper investigates contagion to European stock markets associated with seven big financial shocks between 1997 and 2002. We apply methods using heteroscedasticity-adjusted correlation coefficients to discriminate between contagion, interdependence and breaks in stock markets relationships. The analysis focuses on a comparison between developed Western European markets and emerging stock markets in Central and Eastern Europe. We find modest evidence of significant instabilities in cross-market linkages after the crises. The Central and Eastern European stock markets are not more vulnerable to contagion than Western European markets.     

Financialization of Housing in Brazil: New Frontiers

The financialization of housing has been increasingly identified as an important driver of social and economic change in contemporary capitalism. Focusing on the Brazilian context, this article considers the extent to which recent changes in housing regulations, policies and markets confirm or challenge narratives about the financialization of housing in the international academic debate. I argue that while many of the trends stressed in the literature are apparent, more extreme processes of financialization within the Brazilian housing sector remain limited––not only because of institutional and regulatory constraints, path dependence or political resistance, but also because of fundamental structural conditions of Brazil's position as a peripheral economy. Three different but mutually reinforcing processes are scrutinized in order to evaluate the financialization of housing and its limits in Brazil: the re‐regulation of the real estate financial sector initiated in the 1990s; the changing funding patterns among real estate companies since the mid‐2000s; and the increasing commodification of housing induced by a large‐scale and heavily subsidized housing program launched in 2009.     

Modelling contagion of financial crises

Inspired by the empirical findings, we include international traders to capture linkage between markets and propose a two-market heterogeneous agents model to simulate financial crisis with contagion effect. This paper manages to calibrate sudden crash behavior of US and UK stock markets during “Black Monday” of 1987 besides smooth crisis and disturbing crisis categorized in literature. It is implied that financial crisis and its contagion could be endogenous, which supports a scenario of over-valuation causing a financial crisis. In addition, the model shows that financial system could be fragile in which small shock(s) hitting individual market’s fundamental could cause financial crisis spreading to the other market. This also supports a scenario of external shock triggering a financial crisis. Lastly, to demonstrate the relevance of our model to financial markets, we manage to match typical stylized facts, especially cross-correlation which is exclusive to a multiple-market case.     

Network analysis of exchange data: interdependence drives crisis contagion

In this paper, we examine linear and nonlinear co-movements that appear in the real exchange rates of a group of 28 developed and developing countries. The matrix of Pearson correlation and Phase Synchronous coefficients have been used in order to construct a topology and hierarchy of countries by using the Minimum Spanning Tree (MST). In addition, the MST cost and global correlation coefficients have been calculated to observe the co-movements’ dynamics throughout the time sample. By comparing Pearson and Phase Synchronous information, a new methodology is emphasized; one that can uncover meaningful information pertaining to the contagion economic issue and, more generally, the debate surrounding interdependence and/or contagion in financial time series. Our results suggest some evidence of contagion in the Asian currency crises; however, this contagion is driven by previous and stable interdependence.     

The default contagion of contingent convertible bonds in financial network

This paper investigates the impact of contingent convertible (CoCo) bonds on systemic risk using Eisenberg-Noe’s financial network method, in which the network is linked by debt relationships. As an efficient method for addressing the problem of “too big to fail,” CoCo bonds have received widespread attention, particularly because the trigger for CoCo bonds is a systemic risk event. Thus, the impact of CoCo bonds on systemic risk needs to be addressed. To solve this problem, we adopt default contagion and loss amplification due to network linkage to measure systemic risk, from which we can ascertain the potential impact on it of CoCo bonds. The results show that CoCo bonds enhance the spillover effect of the issuer’s default; meanwhile, sufficient CoCo bonds partly offset the impact of default contagion from other banks. Furthermore, CoCo bonds enhance the amplification effect of loss due to network linkage, but the amplification effect diminishes after the bankruptcy cost is considered. Finally, the numerical test provides some insight into how the issuance of writedown (WD) bonds influences commercial banks in China. Our study not only offers suggestions to the regulators of CoCo bonds but also contributes to related studies.     

European Periphery Crises,International Financial Markets,and Democracy

This article analyzes the origin and causes of the recent economic and financial crises, mainly for the countries located in the periphery of the European Union (EU), as well as their evolution and transformation into social, political, and institutional crises. After explaining the differential impact of the crises on EU economies, we analyze how the economic policies developed thus far not only are unable to resolve the current crisis pattern but also actually entail a risk to the present democratic models by transferring the legitimate control over governments from citizens and democratic parliaments to unelected, nonrepresentative international financial markets.     

A retrospective on the subprime crisis and its aftermath ten years after Lehman’s collapse

This paper reviews the interactions between policymaking, the financial system and the U.S. economy before, during and after the subprime crisis, with particular attention to current controversies about the policy decisions that led to Lehman’s downfall and their lessons for the future. The first part of the paper documents and analyzes the interactions between policy, financial markets and the economy during the acute and subsequent moderate phases of the crisis as well as during the later gradual exit from the zero lower bound and the extremely slow reduction in high powered money and bank reserves. The remaining parts develop alternative aspects of the thesis that mutual uncertainties inflicted by financial institutions on policymakers and by the latter on financial markets were at the root of the non-negligible surprises that the crisis inflicted on everybody. In particular, it discusses the political economy of bailout operations, reviews and evaluates recent controversies about the reasons for not rescuing Lehman Brothers, and informally presents the structure and policy lessons from a general equilibrium model of the financial sector highlighting the consequences of policy actions that have raised (Knightian) bailout uncertainty. The last section takes a brief look ahead and discusses some longer term consequences of the crisis.     

Contagion in global equity markets in 1998: The effects of the Russian and LTCM crises

The Russian and LTCM financial crises in 1998 originated in bond markets, but rapidly transmitted through international equity markets. A multi-factor model of financial markets with multiple regimes is used to estimate the transmission effects in equity markets due to global, regional and contagious transmission mechanisms during the crises. Using a panel of 10 emerging and industrial financial markets, the empirical results show that contagion is significant and widespread in international equity markets during the LTCM crisis, but is more selective during the Russian crisis. Contagion effects in equities differ to those previously noted in bond markets for this period.     

Stock market co-movements: Islamic versus conventional equity indices with multi-timescales analysis

This study examines market co-movements in Islamic and mainstream equity markets across different regions in order to discover contagion during 9 major crises and to measure integration between markets. Using wavelet decomposition to unveil the multi-horizon nature of co-movement, we find that the shocks were transmitted via excessive linkages, while the recent subprime crisis reveals fundamentals-based contagion. While Islamic markets show traces of reduced exposure to the recent crisis owing to low leverage effect, their less diversified portfolio nature increases vulnerability to other crises. We generally find incomplete market integration, with relatively higher fundamental integration for Islamic markets which may be attributable to their real sector allocation nature.     

STOCK‐FLOW INTERACTIONS,DISEQUILIBRIUM MACROECONOMICS AND THE ROLE OF ECONOMIC POLICY

This paper presents the ‘KMGT’ (Keynes–Metzler–Goodwin–Tobin) portfolio model and studies its stability properties. The approach to macrodynamic modelling taken here extends the KMG model of Chiarella and Flaschel (2000) , focusing in particular on the incorporation of financial markets and policy issues. The original KMG model considered three asset markets (equities, bonds and money) but depicted them in a rudimentary way so that they had little influence on the real side of the model. The only financial market influencing the real side of the economy was the money market (via an LM curve theory of interest). Here Tobin's portfolio choice theory models the demand for each asset in such a way that the total amount of assets that households want to hold equals their net wealth, which is a stock constraint attached to portfolio choice. There is also a flow constraint, that the net amount of assets accumulated (liabilities issued) by one sector must equal its net savings (expenditures). The Tobinian macroeconomic portfolio approach characterizes the potential for financial market instability, focusing on the interconnectedness of all three markets. The paper goes on to study the potential for labour market and fiscal policies to stabilize unstable macroeconomies.     

Multiscale financial risk contagion between international stock markets: Evidence from EMD-Copula-CoVaR analysis

Considering the frequency domain and nonlinear characteristics of financial risks, we measure the multiscale financial risk contagion by constructing EMD-Copula-CoVaR models. Using a sample composed of nine international stock markets from January 4, 1999, to May 13, 2021, the empirical study reveals that: (1) EMD-Copula-CoVaR models can effectively measure the multiscale financial risk contagion, and the financial risk contagion is significant at all time scales; (2) The high-frequency component is the major contributor of financial risk contagion; meanwhile, the low-frequency component is the smallest among all time scale components; (3) The risk export of the US financial market to other markets, except the UK under the original and medium-frequency component, is higher than that it receives; and (4) Even though the magnitude of overall financial risk contagion is similar for the COVID-19 pandemic, Subprime Crises, 9/11 terrorist attack and other crises, the relative importance of different frequency components is heterogeneous. Therefore, the countermeasures of risk contagion should be designed according to its multiscale characteristics.     

Interactions between financial constraints and economic growth

The financial economy and the real economy are interconnected through various, complex, and evolving transmission mechanisms, whose literary coverage is far from comprehensive. In this context, we wish to contribute to the literature on the interactions between financial constraints and economic growth. We introduce financial dynamics in the R&D-based growth literature, by bringing Bernanke, Gertler and Gilchrist’s (1999) informational asymmetries into Romer’s (1990) growth model. With the developed framework, our main goal is to examine if and how such asymmetries impact economic growth. We find that the overall impact of this form of financial constraints on long-term growth is negative.     

A Primer on Financial Contagion

Abstract.  This paper presents a theoretical framework to highlight possible channels for the international transmission of financial shocks. We first review the different definitions and measures of contagion adopted by the literature. We then use a simple multi-country asset pricing model to classify the main elements of the current debate on contagion and provide a stylized account of how a crisis in one country can spread to the world economy. In particular, the model shows how crises can be transmitted across countries, without assuming ad hoc portfolio management rules or market imperfections. Finally, tracking our classification, we survey the results of the empirical literature on contagion.     

Asset allocation with contagion and explicit bankruptcy procedures

In this paper, we consider the asset allocation problem of an investor allocating his funds between several corporate bonds and a money market account. In particular, we provide a realistic model of financial distress: firstly, we model Chapter 7 and Chapter 11 bankruptcies as different possible outcomes of financial distress. Secondly, we take into consideration that, in practice, “default” is not the end, but the beginning of financial distress, eventually leading to a reorganization or a liquidation of a distressed firm. Thirdly and most importantly, we are able to analyze the impact of contagion on an investor’s demand for corporate bonds. Contagion is an important phenomenon, as it reduces the investor’s ability to diversify his portfolio, and we show that the bond demand can change by more than 50%.
