Dating The Timeline Of Financial Bubbles During The Subprime Crisis, Peter C. B. Phillips, Jun Yu
Dating The Timeline Of Financial Bubbles During The Subprime Crisis, Peter C. B. Phillips, Jun Yu
Research Collection School Of Economics
A new recursive regression methodology is introduced to analyze the bubble characteristics of various financial time series during the subprime crisis. The methods modify a technique proposed in Phillips, Wu, and Yu (2011) and provide a technology for identifying bubble behavior with consistent dating of their origination and collapse. The tests serve as an early warning diagnostic of bubble activity and a new procedure is introduced for testing bubble migration across markets. Three relevant financial series are investigated, including a financial asset price (a house price index), a commodity price (the crude oil price), and one bond price (the spread …
The Implications Of Sovereign Wealth Fund Investment On Capital Markets: A Bottom-Up View, David Fernandez
The Implications Of Sovereign Wealth Fund Investment On Capital Markets: A Bottom-Up View, David Fernandez
Research Collection Lee Kong Chian School Of Business
The buzz around sovereign wealth funds has been turned down a notch, but they remain a hot topic. The accusations of sovereign wealth funds having hidden agendas remain, but with the very public losses suffered by some during the recent financial turmoil, such talk has even less credibility. And given that most of those losses were from investments in US, UK, and European financial institutions, hope that sovereign wealth funds would be the saviors of Wall Street has also faded. At its base, four trends continue to keep sovereign wealth funds in focus. First, there is the phenomenal rise of …

The Unintended Effects Of The Sarbanes-Oxley Act, Vidhi Chhaochharia, Clemens A. Otto, Vikrant Vig

The Sarbanes-Oxley Act (SOX) was passed in the wake of several scandals that rocked corporate America in 2001 and 2002. The objective behind SOX was to improve corporate governance by improving accounting disclosures. Compliance with Section 404 is considered by many to be the most costly requirement of SOX and has been argued to be a disproportionate burden for small firms. Consequently, firms with a public float below $75 million were granted several exemptions from compliance. We document an unintended effect of these exemptions: a weakening of corporate governance through a weakening of the market for corporate control.
Explosive Behavior In The 1990s Nasdaq: When Did Exuberance Escalate Asset Values?, Peter C. B. Phillips, Yangru Wu, Jun Yu
Explosive Behavior In The 1990s Nasdaq: When Did Exuberance Escalate Asset Values?, Peter C. B. Phillips, Yangru Wu, Jun Yu

A recursive test procedure is suggested that provides a mechanism for testing explosive behavior, date stamping the origination and collapse of economic exuberance, and providing valid confidence intervals for explosive growth rates. The method involves the recursive implementation of a right-side unit root test and a sup test, both of which are easy to use in practical applications, and some new limit theory for mildly explosive processes. The test procedure is shown to have discriminatory power in detecting periodically collapsing bubbles, thereby overcoming a weakness in earlier applications of unit root tests for economic bubbles. An empirical application to the …
The Impact Of Transaction Duration, Volume And Direction On Price Dynamics And Volatility, Anthony S. Tay, Christopher Ting, Yiu Kuen Tse, Mitchell Warachka
The Impact Of Transaction Duration, Volume And Direction On Price Dynamics And Volatility, Anthony S. Tay, Christopher Ting, Yiu Kuen Tse, Mitchell Warachka
Research Collection School Of Economics
We explore the role of trade volume, trade direction, and the duration between trades in explaining price dynamics and volatility using an Asymmetric Autoregressive Conditional Duration model applied to intraday transactions data. Our results suggest that volume, direction and duration are important determinants of price dynamics, while duration is also an important determinant of volatility. However, the impact of volume and direction on volatility is marginal after controlling for duration, and the impact of volume on volatility appears to be confined to periods of infrequent trading.
