国际金融系统风险的放大与传导:对冲基金在金融风暴中的作用

作为国际热钱的代表,对冲基金在2007～2008年金融风暴中究竟起了怎样的作用?本文首先分析了对冲基金在危机中去杠杆化操作的原因及后果;通过构造1171家美国上市银行加权平均投资组合,以其月度收益率作为美国银行业代理变量,采用1994～2008年对冲基金月度数据进行经验论证。研究发现:第一,对冲基金去杠杆化放大了系统风险;第二,对冲基金全行业具有杠杆效应的一致性;第三,对冲基金的收益水平与美国银行业紧密相关,因此,对冲基金的行动是资本市场剧烈波动的影响因素,向美国银行业传导了系统风险,推动了金融风暴的形成。最后,本文提出加强对冲基金监管的思路。     

The ins and outs of mortgage debt during the housing boom and bust

From 1999 to 2013, U.S. mortgage debt doubled before contracting sharply. I estimate mortgage inflows and outflows that shed light on the sources of volatility. During the boom, inflows from real estate investors tripled, far outpacing other segments such as first-time homebuyers. During the bust, a collapse in inflows keyed the debt decline, while an expansion of outflows due to defaults played a more minor role. Inflow declines partly reflect a dramatic falloff in first-time homebuying, especially for low credit score individuals. Further analysis helps support the notion that the differential decline by credit score reflects markedly tightened credit supply.     

WEALTH EFFECTS AND MACROECONOMIC DYNAMICS

The effect of wealth on consumption is an issue of long‐standing interest to economists. Conventional wisdom suggests that fluctuations in household wealth have driven major swings in economic activity both in the United States and abroad. This paper considers the so‐called consumption wealth effects. There is an extensive existing literature on wealth effects that has yielded some insights. For example, research has documented the relationship between aggregate household wealth and aggregate consumption over time, and a large number of household‐level studies suggest that wealth effects are larger for households facing credit constraints. However, there are also many unresolved issues regarding the influence of household wealth on consumption. We review the most important of these issues and argue that there is a need for much more research in these areas as well as better data sources for conducting such analysis.     

Essential concepts necessary to consider when evaluating the efficacy of quantitative easing

The economic impact from quantitative easing (QE) may be much less than assumed by the Federal Reserve. One focus is on the effectiveness of QE to stabilize a failing banking system, and the judgment here is largely positive. A second focus, especially in the US, is on evaluating subsequent rounds of QE that were implemented after the economy had resumed growth and after the banking sector had recapitalized and returned to profitability. For these subsequent rounds of QE, the reviews are decidedly mixed and heavily dependent on the assumptions embedded in the economic models used by the researchers. Researchers willing to assume that the US is a closed domestic economy tend to find a large impact on long-term interest rates from QE. If the US is part of a highly integrated global economy, a smaller effect is presumed. Then there is the more important and controversial evaluation of whether there is any impact on real GDP growth and job creation from QE once the economy is growing again, even if unemployment rates remain historically elevated. What one chooses to ignore or assume does not exist can be more important to the conclusions of QE evaluations than may meet the eye. Inappropriate assumptions can lead to poor decisions.     

The role of on- and off-balance-sheet leverage of banks in the late 2000s crisis

Extensive regulatory changes and technological advances have transformed banking systems to a great extent. Banks have reacted to the challenges posed by the new operating environment by creating new products and expanding their activities to some uncharted business areas. In this paper, we study how modern banking which gave birth to the off-balance-sheet leverage activities affected the risk profile of U.S. banks as well as the level of systemic risk before and after the onset of the late 2000s financial crisis. Towards this, we separate on- from off-balance-sheet leverage and capture the latter with different, yet complementary, measures which do not exist in the current literature. Special attention is paid on the deleveraging process that occurred in the banking market after the crisis erupted, which is an additional innovative feature of this study. Our findings reveal that leverage, both explicit and hidden off-the-balance-sheet, increases the individual risk of banking firms making them vulnerable to financial shocks. Reverse leverage, on the other hand, is beneficial for individual banks’ health, but is found to be harmful for financial stability. We also demonstrate that the banks which concentrate on traditional lines of business typically carry less risk compared to those involved with modern financial instruments.     

Deleveraging,deflation and depreciation in the euro area

During the post-crisis period, economic performance has been highly heterogenous across the euro area. While some economies rebounded quickly after the 2009 output collapse, others are undergoing a protracted further decline as part of an extensive deleveraging process. At the same time, inflation has been subdued throughout the whole of the euro area and intra-euro-area exchange rates have hardly moved. We interpret these facts through the lens of a two-country model of a currency union. We find that deleveraging in one country generates deflationary spillovers which cannot be contained by monetary policy, as it becomes constrained by the zero lower bound. As a result, the real exchange rate response becomes muted, and the output collapse—concentrated in the deleveraging economies.     

金融杠杆、经济增长与金融稳定

本文基于91个国家1983~2012年的面板数据,采用系统GMM估计方法和二元面板离散选择模型对金融杠杆、经济增长与金融稳定之间的关系进行了实证分析。实证结果表明:(1)去杠杆化对经济增长具有显著的负效应,同时,伴随着去杠杆化进程,金融危机的发生概率会明显增加;(2)金融杠杆波动与经济增长和金融稳定均显著负相关,表明金融杠杆波动程度的加大不仅会危害经济增长,同时还会对金融体系的稳定性产生负面影响。上述结论对一国的经济增长与金融稳定具有比较确切的政策启示。首先,应考虑从防患未然的角度,前瞻性地加强金融杠杆的宏观管理,避免整个金融体系出现过度杠杆化的倾向。其次,在危机后“被动去杠杆化”的过程中,应尽可能地采取循序渐近的策略,充分考虑政策实施过程中应有的平滑操作,最大限度地避免金融杠杆急速下降所导致的经济衰退和金融不稳定。
