We construct a comprehensive measure for the evolution of the US financial crisis by extracting the common components in the real estate market (S&P Case-Shiller composite-10 housing price index), the equity market (S&P 500 index), and the money market (M2 money multiplier). We then investigate the effects of this crisis on six Asian economies. Using the quarterly data from Q1 1991 to Q1 2010, we find that, surprisingly, the Asian equity markets are not contagious by the crisis; rather, trade contagion is the dominant transmission channel for the crisis to be transmitted to Asia. Finally, our empirical investigations suggest that monetary policy, rather fiscal policy, is a better choice for assisting Asian economies during this crisis.
The first indications of a global financial crisis emerged in the middle of 2007 with rising defaults on sub-prime mortgages in the US. It began as a relatively isolated crisis in low-quality mortgage loans in US but later spiraled out of control due to the chained and mutually dependent institutional design of the loans, under which the global financial system was contaminated by increased risk-taking in search of higher yields and the use of sophisticated mechanisms such as asset-backed securities and structured credit products. Neither the markets nor the regulators were fully aware of the potential danger of these practices to the financial stability of the system or of the fact that the rate of economic and financial globalization over the last decade had been higher than the speed of policy and regulatory adjustment. Thus, when housing prices started to crash and the default rate of mortgages rose, financial institutions were hit rapidly in most developed countries. Following this, those countries experienced unemployment and a loss of confidence that reduced consumption and investment, which began the economic recession that gave the crisis a worldwide dimension. Several channels are commonly understood to have transmitted the crisis from the US to the world economy. First, the most direct channel is the mutually dependent and highly correlated financial systems of the countries. For instance, Banks in Japan invested in bonds that provided high yields but were backed by low-quality mortgages. Thus, when the sub-prime crisis began in the US, these banks automatically lost their investments. Second, the failure of the US banking system may have caused a shortage of liquidity, leading to capital outflows from the rest of the world back to the US. Third, financial contagion may have resulted in sectoral contagion: persistent liquidity shortages are likely to cause a systematic impact on non-financial sectors as well. One possible explanation for this phenomenon is that a fear of “insolvency” makes banks reluctant to ease their line of credit. Meanwhile, the increasing cost of borrowing caused by strict credit lending can further increase the probability of a firm’s insolvency. Finally, unemployment and a loss of confidence may have changed consumers’ expectations and behaviors, leading to a reduction in consumption. As one of the biggest consumers in the world, decreases in demand in the US would reduce exports in many countries across the world. Such a problem in the global production chain would affect sectors in all countries. In particular, countries that depend on external consumption would suffer if most of their exports were intended for partners affected by the crisis. This paper attempts to study the impact of the financial crisis on a set of Asian countries. To study the side by side impact of the crisis on the Asian countries, the first challenge is to measure the crisis’ evolution. Due to the difficulty to find suitable events during the crisis which can be used as the benchmark to separate the effect of the crisis on the target economy before and after, a standard event-study analysis to investigate the economic effects of the financial crisis on the target economy can be contaminated. Many research efforts have been dedicated to measuring financial crises. For instance, Reinhart and Rogoff (2009) documented many features of financial crises that have occurred over the last 200 years. Reinhart and Rogoff (2008) claimed that the 2007 sub-prime crisis shared many similarities with past crises. However, little is known about measuring a crisis’ evolution. Kaminsky and Reinhart (1999) employed a set of indicators (both fundamental and financial) to describe past crises. However, each indicator only measured one aspect of the crisis and they did not construct an index to capture the evolution of the financial crisis as a whole. In this paper, we construct a simple but comprehensive measure of financial crises to measure the common shocks among various economic indicators as documented in Kaminsky and Reinhart, 1999 and Reinhart and Rogoff, 2008. Intuitively, a financial crisis can be thought as a series of random (negative) shocks. We assume that this series of shocks enters into many economic indicators additively, including housing prices, equity prices and others. We also allow each indicator to contain idiosyncratic shocks that capture the specific features of a particular market or an aspect of the economy. Intuitively, when an exogenous negative shock occurs, the shock enters different aspects of the economy at different rates, and each aspect of the economy responds to the common shock differently. Uncorrelated idiosyncratic shocks persist as well. We employ two disentangling methods for identifying the common financial crisis shocks in this paper: principle component approach, and averaging method, which follows Lumsdaine and Prasad (2003). Principle component approach is widely used to identify the unobserved factor in financial markets. For instance, Baker and Wurgler (2006) use principle component approach to construct the index measuring investment sentiment from several series which are believed to be correlated with investment sentiment in the market. The averaging method used in Lumsdaine and Prasad (2003) is a robust method for identifying the common components of multiple time series. This method allows for non-synchronic entry of common shocks, which captures possible delays in the transmission and responses from each market or each aspect of the economy. Using these two measures of the evolution of the financial crisis, we are able to investigate the economic effects of the crisis on the Asian economy. Many papers have focused on the impacts of the sub-prime crisis within the US. For instance, Foote et al. (2008) claimed that the widespread decline in housing prices was the proximate cause of the sub-prime crisis, Longstaff (2010) investigated the contagion effects of the sub-prime crisis to other financial markets in US, and Duchin et al. (2010) investigated the impacts of the sub-prime crisis on firms’ financing behaviors. In our paper, we focus on the international transmission mechanism instead of focusing on transmissions within the US. One related paper is that of Dooley and Hutchison (2009). Dooley and Hutchison (2009) studied the international transmission mechanism of the sub-prime crisis via an event-study method. They found that a range of financial and economic news emanating from the US had statistically and economically large impacts on 14 emerging markets and that several news events moved markets uniformly. Because they used an “event-study methodology,” they were not able to study countries’ continuous responses to the evolution of the sub-prime crisis. They could not incorporate lagged responses into their analysis, and the time span between two events was too small to accurately identify the effects. Our main contributions are as follows: First, we construct a new measure of the evolution of a financial crisis that can be used to measure the crisis’ impact on various economic and financial activities. In so doing, we avoid the problems facing the event-study method, which originate from the timing uncertainty of the occurrence of a financial crisis. Second, using this financial crisis measure and a sample from Q1 1990 to Q1 2010 for a set of Asian countries including Australia, Japan, India, China, Korea, and Thailand, we examine the sub-prime crisis transmission channels to Asian economies. The rest of the paper is organized as follows. Section 2 describes the methodology used in the paper. Section 3 presents the empirical results and discussion. We conclude afterwards.

In this paper, we proposed a new method for measuring financial crisis evolution. This measure can be used to study the impacts of a financial crisis on other economic and financial activities, which cannot be done with traditional event-study analysis due to the timing uncertainty of financial crises. We employed a sample from Q1 1991 to Q1 2010 for a set of Asian countries including Australia, Japan, India, China, Korea, and Thailand. We demonstrated that the universal crisis transmission channel of the US sub-prime crisis was international trade rather than the capital market. Countries were affected differently and responded with different policies. However, one important implication of our study is that fiscal policy was not as useful as monetary expansion policy in supporting the domestic economy during this crisis. However, inflation may become a problem in the future, and stagflation might be a danger if the world economy does not recover.
