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 …
Bayesian Analysis Of Structural Credit Risk Models With Microstructure Noises, Shirley J. Huang, Jun Yu
Bayesian Analysis Of Structural Credit Risk Models With Microstructure Noises, Shirley J. Huang, Jun Yu
Research Collection School Of Economics
In this paper a Markov chain Monte Carlo (MCMC) technique is developed for the Bayesian analysis of structural credit risk models with microstructure noises. The technique is based on the general Bayesian approach with posterior computations performed by Gibbs sampling. Simulations from the Markov chain, whose stationary distribution converges to the posterior distribution, enable exact ¯nite sample inferences of model parameters. The exact inferences can easily be extended to latent state variables and any nonlinear transformation of state variables and parameters, facilitating practical credit risk applications. In addition, the comparison of alternative models can be based on deviance information criterion …
Hype My Stock: Do Firms Really Want Biased Research?, Roger Loh
Hype My Stock: Do Firms Really Want Biased Research?, Roger Loh
Research Collection Lee Kong Chian School Of Business
Analyst research is alleged to be biased because of conflicts of interest when analysts’ employers underwrite securities for the firms covered. I posit that affiliated analyst optimism should be the strongest for offering firms with a desire to over-inflate stock prices. I hypothesize that a firm’s corporate governance and its CEO incentives are related to the affiliation bias. Using stock recommendations data, I find evidence that the affiliation bias is indeed more pervasive for firms with high CEO wealth sensitivity to stock price (i.e., high CEO delta). The larger affiliation bias for high delta firms remains even after the introduction …
Using High-Frequency Transaction Data To Estimate The Probability Of Informed Trading, Anthony S. Tay, Christopher Ting, Yiu Kuen Tse, Mitchell Warachka
Using High-Frequency Transaction Data To Estimate The Probability Of Informed Trading, Anthony S. Tay, Christopher Ting, Yiu Kuen Tse, Mitchell Warachka
Research Collection School Of Economics
This paper applies the asymmetric autoregressive conditional duration (AACD) model of Bauwens and Giot (2003) to estimate the probability of informed trading (PIN) using irregularly spaced transaction data. We model trade direction (buy versus sell orders) and the duration between trades jointly. Unlike the Easley, Hvidkjaer, and O'Hara (2002) approach, which uses the aggregate numbers of daily buy and sell orders to estimate PIN, our methodology allows for interactions between consecutive buy-sell orders and accounts for the duration between trades and the volume of trade. We extend the Easley–Hvidkjaer–O'Hara framework by allowing the probabilities of good news and bad news …

Exploring A New Financial Paradigm In Social Investment, Arthur R. Wood
Social Space
The business sector can be more involved in financing the work of the social sector. Arthur R. Wood makes his case through the sanitation issue and shares Ashoka’s plans in paving the way for more collaboration between the social and business sectors.

We examine country-level determinants of private information search incentives, and whether analysts’ role in constraining managers’ opportunistic earnings management varies across countries. In a sample of 31,312 firm-year observations originating from 30 countries, we document that: (1) analyst coverage is negatively (positively) related to the level of corporate disclosure (how secretive the national culture is); (2) the negative association between analyst coverage and earnings management is observed in stronger investor protection countries but not in weaker investor protection countries; and (3) analyst monitoring fails to mitigate culturedriven earnings manipulations in countries with more individualistic and uncertainty-tolerant cultures. Taken together, financial …
