系统性金融风险再认识：演化、测量与检验*

本文提供了系统性金融风险的演化机制,提出了优化后的系统性金融风险测量体系,并实证检验了测量体系的功能,旨在从理论和操作上为准确、全面地测量系统性金融风险提供新的认识。研究结果表明：在系统性金融风险演化过程中,资产价格与商品价格作为演化载体可以实时监测风险的大小,而国民经济各部门的杠杆率作为演化载体可以先行预测风险的大小。因而,从价格与杠杆率两个维度提出的测量体系,能够反映系统性金融风险的变化。在对测量体系实证检验后,监测指标识别出了金融系统压力较大的时期,预测指标识别出了国民经济杠杆率较高的时期,印证了价格型变量的监测功能与杠杆率型变量的预测功能。     

Liberalization,Regulatory Delays and Vulnerability to Systemic Banking Crisis

This work aims at contributing to the improvement of the early warning systems of banking crises using a new approach accounting for model uncertainty. We show that a multinomial logit model based on Bayesian model averaging (BMA) is a good strategy to predict banking crisis. To do this, we argue that differences in vulnerability to banking crisis can be largely explained by an asymmetry between financial market evolution and regulation update on a sample of 49 developed and developing countries between 1980 and 2010. When markets are liberalized, competition pushes bankers to take more risks and take advantage of regulatory delays thus increasing crises probabilities. Our empirical evidence supports that crisis probability is higher in country liberalizing their banking system when regulation is not updated. We developed an early warning system for systemic banking crises based on the multinomial logit model. Its main difference to existing prediction models and its contribution to the literature is that it is intended to identify and resolve what is called by Bussiere and Fratzscher [(2006). Towards a new early warning system of financial crises. Journal of International Money and Finance, 25(6), 953–973] as post-crisis bias in binomial models and to develop a new methodology of leading indicators selection based on BMA. Overall, our model predicts all banking crises during our sample period.     

The role of global financial conditions for credit supply in EMU periphery countries

The article analyses the role of global financial conditions for credit supply and growth performance in individual member states of the European Monetary Union (EMU). In line with the risk-taking channel of monetary policy, we find that in the short run, the Fed and European Central Bank (ECB) interest rate policy compensate for changes in global risk assessment thereby supporting net private credit flows to the European periphery. However, in later periods, a worsened risk sentiment weighs on credit flows to these countries. In contrast, EMU core countries are generally less affected by global financial shocks. This asymmetric influence of global conditions on EMU member states are smoothed by the uniform access of commercial banks to the Eurosystem’s open market operations in conjunction with the redistribution of liquidity via the TARGET mechanism.     

Momentum crash,credit risk and optionality effects in bear markets and crisis periods: evidence from the US stock market

This study explores whether the credit risk anomaly exhibits option-like behaviour similar to the momentum anomaly. It finds that the inverted credit risk spread indeed displays option-like behaviour in bear market states. Unlike a momentum portfolio, which is effectively a short call option on the market, an inverted credit risk portfolio appears to be a long call option on the market.     

Bank risk proxies and the crisis of 2007/09: a comparison

The global financial crisis has again shown that it is important to understand the emergence and measurement of risks in the banking sector. However, there is no consensus in the literature which risk proxy works best at the level of the individual bank. A commonly used measure in applied work is the Z-score, which might suffer from calculation issues given poor data quality. Motivated by the variety of bank risk proxies, our analysis reveals that nonperforming assets are a well-suited complement to the Z-score in studies of bank risk.     

Putting Culture in its Place? A Critical Engagement with Cultural Political Economy

Ngai-Ling Sum and Bob Jessop present Cultural Political Economy (CPE) as a project that seeks to deepen Critical Political Economy (C*PE) through an engagement with the cultural turn. This article critically assesses their success in such an enterprise. It begins by framing CPE within Jessop and Sum’s previous work on the Regulation Approach, in order to show why the former can only be understood as the result of a critical dialogue with the latter. Next, my reconstruction of the main elements of Sum and Jessop’s CPE is presented. After having carefully examined its main assumptions and concepts, I criticise CPE’s main novel element, an ontological cultural turn, due to the culturalist risks it engenders. In order to substantiate and exemplify that theoretical criticism, I review CPE’s application to the analysis of the North Atlantic Financial Crisis. This article concludes by showing the main difficulties that CPE faces as an alternative for deepening C*PE and proposes the Amsterdam School of Transnational Historical Materialism as a more suitable direction in which that initiative could be advanced.     

Effect of investor fear on Australian financial markets

We examine the relationship between changes in the level of investor fear (proxied by the ASX 200 implied volatility index) and Australian financial market returns. We document a statistically significant relationship, across asset classes, where returns decline as investor fear increases. Returns are more sensitive to changes in the level of investor fear during the financial crisis of 2008–2009, when investor fear spikes sharply. Taken together, the results confirm that Australian financial market returns are closely related to prevailing levels of investor fear.     

Diversification Bias and the Law of One Price: An Experiment on Index Mutual Funds

Individual investors select high-fee index mutual funds despite the fact that the future payouts are nearly identical. The authors offer an explanation for this violation of the law of one price based on investor desire to diversify. While diversification in some settings may be beneficial, in the case of assets with identical payouts, fee minimization is the only rational strategy. The evidence confirms that investors diversify by selecting multiple higher fee funds rather than minimizing fees when investing in index mutual funds.     

Banking System Reform in China: The Challenges to Improving Its Efficiency in Serving the Real Economy

The Chinese banking system reform since the country's accession to the World Trade Organization has yielded remarkable success. The major listed commercial banks have improved their operational performance significantly. However, there are some signs of changes in their financial results recently. The expanding debt of non‐profitable enterprises and local governments raises a question on the achievements of the previous reform. Considering that the competition among banks will become severer with financial liberalization under slower economic growth, the banks and supervisory authorities must continue to make greater efforts towards further reform in order to improve the banks' corporate governance and the risk management system.     

China's New Role in the International Financial Architecture

The rise of China is challenging the international financial architecture in a number of ways. This paper highlights three that are of critical importance: the challenge of absorbing massive Chinese savings; the incorporation of China into a cohesive global financial safety net; and the organisation of China's participation in funding the demand for international investment projects. The global financial architecture needs to be reformed. But what role should China play? The paper defines the options open to China and the opportunities and barriers it will face. We argue that China can work with the established economic powers in reforming the existing architecture. At the same time, China seeks cooperation in building new institutions and organisations that fill gaps in the existing arrangements. But no matter how international financial diplomacy plays out in the near term, deep financial and economic reform at home will alone deliver China a central role in the international financial architecture. Domestic reform could also attend to some of the challenges that currently plague China's impact on the system. The success or failure of these domestic reforms will be at the crux of the strength or fragility of the international financial architecture in the years ahead.
