Dating The Timeline Of Financial Bubbles During The Subprime Crisis, Peter C. B. Phillips, Jun Yu Nov 2009

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 …


Explosive Behavior In The 1990s Nasdaq: When Did Exuberance Escalate Asset Values?, Peter C. B. Phillips, Yangru Wu, Jun Yu Nov 2009

Explosive Behavior In The 1990s Nasdaq: When Did Exuberance Escalate Asset Values?, Peter C. B. Phillips, Yangru Wu, Jun Yu

Research Collection School Of Economics

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. Some asymptotic properties of the Evans …


Foreign Direct Investment And Foreign Portfolio Investment Under Asymmetric Information, Ruanjai Suwantaradon Oct 2009

Foreign Direct Investment And Foreign Portfolio Investment Under Asymmetric Information, Ruanjai Suwantaradon

Research Collection School Of Economics

This paper develops a model of international capital flows when there is asymmetric information between foreign investors and domestic managers. Direct investors have a direct influence on the management, thus overcoming agency and information problems. This information advantage, however, comes at the cost of having to acquire management expertise. The tradeoff between management costs and the costs of asymmetric information consequently determines the level and composition of a country’s international capital flows. Analyzing how this tradeoff changes with economic conditions in a country, the model can qualitatively capture the experiences of many crisis countries during the 1990s. Specifically, the model …


Monetary Policy And Asset Prices In A Small Open Economy: A Factor-Augmented Var Analysis For Singapore, Hwee Kwan Chow, Keen Meng Choy Oct 2009

Monetary Policy And Asset Prices In A Small Open Economy: A Factor-Augmented Var Analysis For Singapore, Hwee Kwan Chow, Keen Meng Choy

Research Collection School Of Economics

The ongoing global financial turmoil has revived the question of whether central bankers ought to tighten monetary policy preemptively in order to head off asset price misalignments before a sudden crash triggers financial instability. This study explores the issue of the appropriate monetary policy response to asset price swings in the small open economy of Singapore. Empirical analysis of monetary policy based on standard VAR models, unfortunately, is often hindered by the use of sparse information sets. To better reflect the extensive information monitored by Singapore’s central bank, including global economic indicators, we augment a monetary VAR model with common …


Simulation-Based Estimation Of Contingent-Claims Prices, Peter C. B. Phillips, Jun Yu Sep 2009

Simulation-Based Estimation Of Contingent-Claims Prices, Peter C. B. Phillips, Jun Yu

Research Collection School Of Economics

A new methodology is proposed to estimate theoretical prices of financial contingent claims whose values are dependent on some other underlying financial assets. In the literature, the preferred choice of estimator is usually maximum likelihood (ML). ML has strong asymptotic justification but is not necessarily the best method in finite samples. This paper proposes a simulation-based method. When it is used in connection with ML, it can improve the finite-sample performance of the ML estimator while maintaining its good asymptotic properties. The method is implemented and evaluated here in the Black-Scholes option pricing model and in the Vasicek bond and …


Subnational Credit Rating: A Comparative Review, Lili Liu, Kim Song Tan Aug 2009

Subnational Credit Rating: A Comparative Review, Lili Liu, Kim Song Tan

Research Collection School Of Economics

This paper surveys methodological issues in subnational credit ratings and highlights key challenges for developing countries. Subnational borrowing from capital markets has been on the rise owing to fiscal decentralization and demand for infrastructure investments. A prerequisite for accessing capital markets, subnational credit ratings have also emerged as a part of broader reform for fiscal sustainability. They facilitate a more transparent budgetary and financial management system. The global financial crisis makes subnational credit ratings more relevant, as they contribute to fiscal risk evaluations and fiscal adjustment. In addition to subnationals’ own credit strength, the creditworthiness of the sovereign and the …


Asian Currency Baskets: An Answer In Search Of A Question?, Charles Adams, Hwee Kwan Chow Jul 2009

Asian Currency Baskets: An Answer In Search Of A Question?, Charles Adams, Hwee Kwan Chow

Research Collection School Of Economics

This paper considers how a regional currency basket and the associated divergence indicators could be used in official surveillance. Recently, proponents of Asian currency baskets have referred to the role the ECU played in constructing exchange rate divergence indicators in Europe as evidence of the intrinsic usefulness of currency baskets for exchange rate monitoring. We show in this paper a number of problems with the use of regional currency-basket based divergence indicators. First, at a technical level, such indicators involve tracking regional exchange rates against a moving currency basket and can obscure underlying movements in bilateral exchange rates. Second, currency …


Discrete Choice Modeling With Nonstationary Panels Applied To Exchange Rate Regime Choice, Sainan Jin Jun 2009

Discrete Choice Modeling With Nonstationary Panels Applied To Exchange Rate Regime Choice, Sainan Jin

Research Collection School Of Economics

This paper develops a regression limit theory for discrete choice nonstationary panels with large cross section (N) and time series (T) dimensions. Some results emerging from this theory are directly applicable in the wider context of M-estimation. This includes an extension of work by Wooldridge [Wooldridge, J.M., 1994. Estimation and Inference for Dependent Processes. In: Engle, R.F., McFadden, D.L. (Eds.). Handbook of Econometrics, vol. 4, North-Holland, Amsterdam] on the limit theory of local extremum estimators to multi-indexed processes in nonlinear nonstationary panel data models. It is shown that the maximum likelihood (ML) estimator is consistent without an incidental parameters problem …


An Empirical Analysis Of Stock Market Integration: Comparison Study Of Singapore And Malaysia, Zheng Yi, Swee Liang Tan Jun 2009

An Empirical Analysis Of Stock Market Integration: Comparison Study Of Singapore And Malaysia, Zheng Yi, Swee Liang Tan

Research Collection School Of Economics

Using a GARCH (1,1) model, this paper compares the extent to which financial sector liberalization in Singapore and Malaysia each has led to integration of its domestic equity market with external markets. The results show that the level of integration of the domestic markets with the external markets is higher when MSCI regional and global data are used, as compared to when individual country data are used to proxy regional and global markets. Inferences are made about the preferred pace of liberalization in Singapore, as well as, the impact of the Asian financial crisis and capital control measures imposed in …


Hype My Stock: Do Firms Really Want Biased Research?, Roger Loh May 2009

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 May 2009

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 …


Misaligned Incentives And Mortgage Lending In Asia, Richard Green, Roberto S. Mariano, Andrey Pavlov, Susan Wachter Mar 2009

Misaligned Incentives And Mortgage Lending In Asia, Richard Green, Roberto S. Mariano, Andrey Pavlov, Susan Wachter

Research Collection School Of Economics

This paper provides a conceptual basis for the price discovery potential for tradable market instruments and specifically the development of mortgage securitization in Asia and the potential dangers of such markets. Nonetheless we argue for the potential importance of securitization in Asia because of its possible role in increasing transparency of the financial sector of Asian economies. We put forth a model explaining how misaligned incentives can lead to bank generated real estate crashes and macroeconomic instability, with or without securitization under certain circumstances. We examine the banking sector’s performance in Asia compared to securitized real estate returns, to provide …


Can Liquidity Shifts Explain The Lockup Expiration Effect In Stock Returns?, Chandrasekhar Krishnamurti, Avanidhar Subrahmanyam, Tiong Yang Thong Feb 2009

Can Liquidity Shifts Explain The Lockup Expiration Effect In Stock Returns?, Chandrasekhar Krishnamurti, Avanidhar Subrahmanyam, Tiong Yang Thong

Research Collection Lee Kong Chian School Of Business

Several studies on the expiration of IPO lockups document a strong negative reaction even though the unlock event is devoid of any informational content. The empirical finding has remained a conundrum. In this paper, we find that changes in liquidity can account for the observed stock price reaction around lockup expiration. Specifically, firms which show improvement in liquidity subsequent to the unlock day experience positive abnormal returns in the post-expiration period, and vice versa. Another interesting conclusion that emerges from our research is that liquidity changes can predict future abnormal returns. Our results remain robust to the use of alternate …


Analyzing And Forecasting Business Cycles In A Small Open Economy: A Dynamic Factor Model For Singapore, Hwee Kwan Chow, Keen Meng Choy Feb 2009

Analyzing And Forecasting Business Cycles In A Small Open Economy: A Dynamic Factor Model For Singapore, Hwee Kwan Chow, Keen Meng Choy

Research Collection School Of Economics

A dynamic factor model is applied to a large panel dataset of Singapore’s macroeconomic variables and global economic indicators with the initial objective of analyzing business cycles in a small open economy. The empirical results suggest that four common factors are present in the quarterly time series, which can broadly be interpreted as world, regional, electronics and domestic economic cycles. The estimated factor model explains well the observed fluctuations in real economic activity and price inflation, leading us to use it in forecasting Singapore’s business cycles. We find that the forecasts generated by the factors are generally more accurate than …


Markov Switching Var Model Of Speculative Pressure: An Application To The Asian Financial Crisis, Gregorio Iii Alfredo Vargas Jan 2009

Markov Switching Var Model Of Speculative Pressure: An Application To The Asian Financial Crisis, Gregorio Iii Alfredo Vargas

Dissertations and Theses Collection (Open Access)

Markov switching models with time-varying transition probabilities address the limitations of the earlier methods in the early warning system literature on currency crises. Most of the Markov switching models in the literature are largely based on univariate models of exchange rate fluctuations. In this thesis, the components of the index of speculative pressure are modeled using the Markov Switching VAR with time-varying transition probabilities of Martinez Peria (2002). Two approaches, both of which are derived from this model, are taken to determine the probability of a currency crisis: the probability of a turbulent regime and the expected value of the …


Multivariate Garch Models For The Greater China Stock Markets, Xiaojun Song Jan 2009

Multivariate Garch Models For The Greater China Stock Markets, Xiaojun Song

Dissertations and Theses Collection (Open Access)

This paper reviews the commonly used multivariate GARCH models and uses the daily data of the four Greater China region stock markets, namely Hongkong, Shanghai,Shenzhen, and Singapore, and data of Japan as one ex-ogenous variable to investigate the volatility and shocks spillover behavior and to establish the market linkage among the four markets. We find that the volatility spillover between Shanghai and Shenzhen is obvious and correlation contagion is detected. Conditional variance and conditional correlations are time varying and dynamic which conforms to the arguments in most of the literature. Shanghai and Shenzhen present a very high correlation level during …
