Housing market volatility connectedness among G7 countries

This study investigates international linkages among housing markets in the G7 countries, using the connectedness methodology developed in Diebold and Yilmaz (2012, 2015). We find that volatility connectedness varies over the business cycle, with a surge during the global financial crisis. We also show that the United States and Italy were major net transmitters of housing market volatility shocks to other countries during the global financial crisis and the European debt crisis, respectively.     

Markets contagion during financial crisis: A regime-switching approach

Within a Markov regime-switching VAR framework, we investigate the contagion effects among the stock market, real estate market, credit default market, and energy market covering the most recent financial crisis period when markets experience regime shifts. The results demonstrate that the watershed of regimes occurs around the start of the subprime crisis in 2007, after which the “risky” regime dominates the evolution of market chaos. During the financial crisis, excluding their own shocks, stock market shock and oil price shock are the main driving forces behind the credit default market and stock market variations, respectively. The energy market also appears to be more responsive to the stock market movements than the shocks originating from housing and credit markets. However, the impacts from the credit default market on the real estate market are not significant as expected.     

Global imbalances,cross-market linkages,and the financial crisis: A multivariate Markov-switching analysis

Based on multivariate Markov-switching models, this paper presents new results on the interactions between global imbalances, credit spreads, housing markets, macroeconomic variables, commodities and equities during Q1-1987/Q1-2011. We show that rising global imbalances and the uncontrolled development of the US mortgage and housing markets have been deeply destabilizing the economy, with various shocks impacting subsequently equity markets and macroeconomic variables. But we also uncover, surprisingly, that the cross-market linkages with the commodity markets are strong. Finally, we identify that the US housing market lies at the epicenter of the crisis through its multiple and highly significant interactions with the other variables in the system (including the global imbalances). Sub-samples and alternative time series estimates are provided to check the statistical congruency of the various models.     

House price,mortgage premium,and business fluctuations

This paper investigates the transmission mechanism of mortgage premium to characterize the relationship between the housing market and business cycle for the U.S. We find that mortgage premium is crucial for the amplification and propagation of the model to match the main properties of U.S. housing market and business cycles. The counterfactual analysis suggests that had the Federal Reserve raised the interest rate in 2003Q1, it would have curbed the housing market boom before the crisis, yet failed to alleviate the precipitous decline in housing market activity after the crisis. Moreover, the pre-emptive monetary policy aimed to contain the housing market boom can effectively lower volatilities of major economic aggregates; however, it also exerts a significantly negative effect on the levels of these economic aggregates. Thus, using monetary policy to stabilize asset price inflation involves a trade-off between the volatility and the level of economic activity.     

The eurozone financial crisis: debt,credit ratings and monetary and fiscal policy

This paper discusses the eurozone financial crisis. It argues that it was largely the result of a common monetary policy not being suitable for individual countries which led to excessive private and public borrowing and a debt crisis. Neither borrowing rates nor credit ratings anticipated the crisis. Fundamental changes to eurozone governance are being proposed. The paper examines whether instead there might be a market solution if financial markets priced risk better. Accordingly, a more timely way of obtaining credit ratings is shown.     

信用货币、金融危机与国际金融合作

全球金融危机对传统的以美联储为主导的金融调控方式及美元在世界经济中所扮演的角色提出了严峻的挑战。导致全球金融危机的根源是美国经济的畸形发展与国际金融体制的固有缺陷。化解本次金融危机的出路在于,各国之间要加强政策协调和进行国际货币体制改革,各国央行要采取协调合作的干预措施,共同制订新的国际金融条例,建立广泛的国际金融合作体系。本文首先分析了信用货币的发展及其监管困境,接着对全球金融危机的深层根源进行研究,最后提出了通过加强国际金融合作和改革国际货币体系来应对全球金融危机的建议。     

Do stress tests matter? A study on the impact of the disclosure of stress test results on European financial stocks and CDS markets

During the recent sovereign debt crisis, the European Banking Authority conducted two stress tests on European banks in order to gauge their capital needs, core Tier-1 ratios and ratios of resilience to adverse shocks. We assess the informational content of the disclosure of the stress test outcomes. We conclude that the stress tests conveyed new information and that the outcomes were not anticipated by the stock market but were partially anticipated by the credit default swap (CDS) market. However, while the stock market reacted to the disclosure of the stress test outcomes, in the CDS market there is some evidence of a ‘reverse’ reaction. Moreover, the publication of the outcomes of the stress tests had a stronger impact on the stock prices of riskier financial institutions. A similar pattern is evident in the CDS market, albeit narrowed to one of the stress tests and amid the financial institutions with higher perceived credit risk.

The interbank market during a crisis

The autumn of 1998 provides a setting in which to test the performance of the interbank market during a potential financial crisis. This period witnessed Russia's effective default on its sovereign bonds and the near collapse of the hedge fund Long-Term Capital Management. Despite these negative shocks to bank capital and increased uncertainty in financial markets, the federal funds market still effectively channeled liquidity to those institutions in need at rates consistent with Federal Reserve intentions. Further, risk premiums on overnight lending were largely unaffected and lending volumes increased, suggesting that the federal funds market performed well during this period.

Wealth effects on the housing markets: Do market liquidity and market states matter?

This paper analyzes the effect of household wealth (including housing and financial wealth) on housing sales and probes their long-run and short-run dynamic relationships. We further examine the short-run effect of financial wealth on housing sales by employing quantile regressions, restricted upon different liquidity (quantile) levels and up-down housing markets, from which the differences between the early and late stages of an uptrend/downtrend can be respectively exhibited. We find that housing wealth, income, and mortgage rates have long-run influences on housing sales. Looking at the short run, we find that housing sales only respond to housing wealth and mortgage rates. When we distinguish the effects of financial wealth on housing sales in up-down housing markets, we note a positive influence of financial wealth on housing sales in down markets, but not in up markets. Particularly, our results show an impact of housing liquidity on the short-run relationships.     

HOUSING MARKETS AND THE GLOBAL FINANCIAL CRISIS: THE COMPLEX DYNAMICS OF A CREDIT SHOCK

We analyze the multiple channels of influence that global financial crisis‐induced credit restrictions had on New Zealand's subnational housing markets. The dynamics caused by the credit shock are compared to those caused by a migration shock, a more common form of housing shock in New Zealand. We focus on the impacts on two outcome variables, house prices and housing supply, within a structural time series model of regional housing markets. Both shocks cause substantial and prolonged cyclical adjustments in each variable. Similar cyclical dynamics could complicate the conduct of macroprudential policies designed to affect bank credit allocation. (JEL E32, E44, R21)     

Feedback effects between credit ratings and financial markets

Credit rating agencies often make sharp adjustments in their pronouncements during times of stress in financial markets. These adjustments typically happen with a delay relative to shocks in market prices. Since prices convey information about what market participants are doing and thinking, it is likely that rating agencies take into account market prices when issuing their pronouncements.In order to understand the relationship between credit ratings and financial prices, we develop a model of debt roll-over in which rating agencies incorporate information publicly available in financial markets. We find that (1) rating agencies respond to market prices, i.e. nonfundamental price volatility can shift financing conditions from a low risk spread and high credit rating equilibrium to an equilibrium with high spread and low rating, and (2) rating agencies can anchor expectations about the equilibrium in financial markets, thus serving as an antidote to nonfundamental price volatility.     

THE ROLE OF HOUSE PRICES IN THE MONETARY TRANSMISSION MECHANISM ACROSS EUROPEAN COUNTRIES

This paper provides a discussion of the ‘housing market’ channels of the monetary transmission mechanism and offers some evidence of institutional differences in the European housing and mortgage markets. Using a number of Vector Autoregressive models, estimated individually for nine European countries over the pre‐EMU period, we find that house prices are significantly affected by interest rate shocks. The relative role of these interest‐rate‐induced fluctuations in house prices for private consumption is then investigated. We show that house prices may enhance the effects of interest rate shocks on consumer spending in those economies where housing and mortgage markets are relatively more developed and competitive.     

Do the GSEs expand the supply of mortgage credit? New evidence of crowd out in the secondary mortgage market

The dramatic government takeover of Fannie Mae and Freddie Mac in September, 2008 was motivated in part by a desire to ensure a continued flow of credit to the mortgage market. This study examines a closely related issue: the extent to which GSE activity crowds out mortgage purchases by private secondary market intermediaries. Evidence of substantial crowd out suggests that government support for the GSEs may be less warranted, whereas the absence of crowd out implies that GSE loan purchases enhance liquidity.Using 1994–2008 HMDA data for conventional, conforming sized loans, three distinct periods with regard to GSE crowd out are apparent. From 1994 to 2003, the share of loans sold to the secondary market increased from 60 to over 90%, private sector and GSE market shares of loan purchases were roughly similar for most market segments, and IV estimates indicate relatively little GSE crowd out of private secondary market purchases. From 2004 to 2006, private loan purchases boomed and dominated those of the GSEs, while IV estimates indicate crowd out jumped to 50% at the peak of the boom. This is especially true in the market for home purchase as opposed to refinance loans. With the crash in housing and mortgage markets in 2007, private sector intermediaries pulled back, the GSEs regained market share, and evidence of GSE crowd out disappeared in both the home purchase loan and refinance markets. These patterns suggest that the degree of GSE crowd out varies with market conditions and that the federal takeover of Fannie Mae and Freddie Mac likely served to enhance liquidity to the mortgage market during the 2007–2009 financial crisis.     

The Relationship Between Saving and Credit from a Schumpeterian Perspective

After 1995, the United States experienced housing and mortgage booms, fuelled by increased lending from less regulated institutions, such as hedge funds. At the micro level, the housing boom may have left families with more wealth, but the mortgage boom may have increased their financial vulnerability. Using the Federal Reserve’s Survey of Consumer Finances, we consider both wealth creation and a select number of financial vulnerability measures of homeowners. The data indicate that the housing boom was not only associated with larger house values, but also moderated wealth gains and substantially greater financial vulnerability of homeowners. Both trends were more pronounced among middleincome and Hispanic families, who saw larger wealth gains, but also greater increases in financial vulnerability than their counterparts. Given the breadth of the spread in homeowners’ financial vulnerability alongside sharply higher house prices, our results support the link between more deregulated financial markets and rising financial instability.     

基于风险转移模型的次贷危机传导研究

The effects of financial crisis on fiscal positions

The recent financial crisis was characterized by the sizeable fiscal cost of banking sector bail out operations and the significant automatic and discretionary fiscal policy response to shrinking output, which have put increased pressure on public finances in many industrialized countries. This paper tries to evaluate the impact of financial crisis episodes on debt developments. The findings indicate that severe financial crisis episodes increase the stock of debt by 2.7%–4.0% of GDP, on average in the 20 OECD countries examined. Ιn countries with big financial sectors it ranges from 4.2%–5.3% of GDP and in countries with smaller financial sectors it is about 1.4%–1.7% of GDP. The primary balance and the cyclically adjusted fiscal policy stance ease by about 2.6% of GDP and 1.6% of potential GDP, respectively, in the event of a severe financial market crash. Expansionary fiscal interventions are more pronounced in countries with sizable financial sectors. I find significant evidence that a financial market collapse paves the way for a subsequent deterioration in debt ratios.
