This paper investigates the impact of social-network connections to politicians on firm value. We focus on the networks of university classmates and alumni among directors of U.S. public firms and congressmen. Using the Regression Discontinuity Design based on close elections from 2000 to 2008, we identify that a director’s connection to an elected congressman causes a Weighted Average Treatment Effect on Cumulative Abnormal Returns of -2.65% surrounding the election date. The effect is robust and consistent through various specifications, parametric and nonparametric, with different outcome measures and social network definitions, and across many subsamples. We find evidence to support the …
International Capital Flows With Limited Commitment And Incomplete Markets, Jürgen Von Hagen, Haiping Zhang
International Capital Flows With Limited Commitment And Incomplete Markets, Jürgen Von Hagen, Haiping Zhang
Research Collection School Of Economics
Recent literature has proposed two alternative types of financial frictions, i.e., limited commitment and incomplete markets, to explain the patterns of international capital flows between developed and developing countries observed in the past two decades. This paper integrates both types of frictions into a two-country overlapping-generations framework to facilitate a direct comparison of their effects. In our model, limited commitment distorts the investment made by agents with different productivity, which creates a wedge between the interest rates on equity capital vs. credit capital; while incomplete markets distort the investment among projects with different riskiness, which creates a wedge between the …
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 …
Ingredients For Creating And Sustaining Growth For The Long Term, Singapore Management University
Ingredients For Creating And Sustaining Growth For The Long Term, Singapore Management University
Perspectives@SMU
It is easy to explain why organisations need and want to grow. This applies not only to bottom line-oriented companies, but also non-profit entities. Just like the same way business management skills can and should be applied to public sector and not-for-profit set-ups, these organisations do seek growth too. However, while it is easy to engineer short spurts of growth one way or another, what differentiates a successful organisation from one less so, is whether this organisation can sustain growth over the long-term and achieve continuous success.
Money, Bargaining, And Risk Sharing, Nicolas L. Jacquet, Serene Tan
Money, Bargaining, And Risk Sharing, Nicolas L. Jacquet, Serene Tan
Research Collection School Of Economics
We investigate the dual role of money as a self-insurance device and a means of payment when perfect risk sharing is not possible, and when the two roles of money are disentangled. We use a variant of Lagos–Wright (2005) where agents face a risk in the centralized market (CM): in the decentralized market (DM) money’s main role is as a means of payment, while in the CM it is as a self-insurance device. We show that state-contingent inflation rates can improve agents’ ability to self-insure in the CM, thereby improving the terms of trade in the DM. We then characterize …
Testing For Multiple Bubbles, Peter C. B. Phillips, Shu-Ping Shi, Jun Yu
Testing For Multiple Bubbles, Peter C. B. Phillips, Shu-Ping Shi, Jun Yu
Research Collection School Of Economics
Identifying explosive bubbles that are characterized by periodically collapsing behavior over time has been a major concern in the literature and is of great importance for practitioners. The complexity of the nonlinear structure in multiple bubble phenomena diminishes the discriminatory power of existing tests, as evidenced in early simulations conducted by Evans (1991). Multiple collapsing bubble episodes within the same sample period make bubble diagnosis particularly difficult and complicate attempts at econometric dating. The present paper systematically investigates these issues and develops new procedures for practical implementation and surveillance strategies by central banks. We show how the testing procedure and …
Grey Market For Indian Ipos: Investor Sentiment And After-Market Performance, Chandrasekhar Krishnamurti, Tiong Yang Thong, Vishwanath Ramanna
Grey Market For Indian Ipos: Investor Sentiment And After-Market Performance, Chandrasekhar Krishnamurti, Tiong Yang Thong, Vishwanath Ramanna
Research Collection Lee Kong Chian School Of Business
Extant research on developed markets shows that investor sentiment is a prominent feature in IPO grey markets. There is sparse work in the context of emerging markets. We fill this lacuna by studying the working of the Indian IPO market. We consider this work interesting and relevant for the following reasons. First, grey market trading always involves short-selling as securities are not yet available. Since legal and institutional environment is less developed in emerging markets, the functioning of grey markets is of interest to policy makers and financial economists. Second, retail investors participate to a greater extent in IPOs of …
Specification Sensitivities In Right-Tailed Unit Root Testing, Shu-Ping Shi, Peter C. B. Phillips, Jun Yu
Specification Sensitivities In Right-Tailed Unit Root Testing, Shu-Ping Shi, Peter C. B. Phillips, Jun Yu
Research Collection School Of Economics
Right-tailed unit root tests have proved promising for detecting exuberance in economic and financial activities. Like left-tailed tests, the limit theory and test performance are sensitive to the null hypothesis and the model specification used in parameter estimation. This paper aims to provide some empirical guidelines for the practical implementation of right-tailed unit root tests, focusing on the sup ADF test of Phillips, Wu and Yu (2011), which implements a right-tailed ADF test repeatedly on a sequence of forward sample recursions. We analyze and compare the limit theory of the sup ADF test under different hypotheses and model specifications. The …
Recent Developments In European Bank Competition, Juliana Yu Sun
Recent Developments In European Bank Competition, Juliana Yu Sun
Research Collection School Of Economics
This paper investigates the degree of bank competition in the euro area, the U.S. and U.K. before and after the recent financial crisis, and revisits the issue whether the introduction of EMU and the euro have had any impact on bank competition. The results suggest that the level of bank competition converged across euro area countries in the wake of the EMU. The recent global financial crisis led to a fall in competition in several countries and especially where large credit and housing booms had preceded the crisis...
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 Unintended Effects Of The Sarbanes-Oxley Act, Vidhi Chhaochharia, Clemens A. Otto, Vikrant Vig
Research Collection Lee Kong Chian School Of Business
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.
Corrigendum To "A Gaussian Approach For Continuous Time Models Of The Short Term Interest Rate", Peter C. B. Phillips, Jun Yu
Corrigendum To "A Gaussian Approach For Continuous Time Models Of The Short Term Interest Rate", Peter C. B. Phillips, Jun Yu
Research Collection School Of Economics
An error is corrected in Yu and Phillips (2001) (Econometrics Journal, 4, 210-224) where a time transformation was used to induce Gaussian disturbances in the discrete time equivalent model. It is shown that the error process in this model is not a martingale and the Dambis, Dubins-Schwarz (DDS) theorem is not directly applicable. However, a detrended error process is a martingale, the DDS theorem is applicable, and the corresponding stopping time correctly induces Gaussianity. We show that the two stopping time sequences differ by O(a2), where a is the pre-specified normalized timing constant.
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
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. An empirical application to the …
Analysis Of Singapore's Foreign Exchange Market Microstructure, Chee Wai Wan
Analysis Of Singapore's Foreign Exchange Market Microstructure, Chee Wai Wan
Dissertations and Theses Collection (Open Access)
This paper analyses the Singapore foreign exchange market from a microstructure approach. Specifically, by applying and modifying the empirical methodology designed by Bollerslev and Melvin (1994), we examine the relationship between bid-ask spreads and the underlying volatility of the USD/SGD. Our data set comprises high-frequency USD/SGD tick data of three separate years (April-June 1989, April-May 2006, April-May 2009). We found that for the USD/SGD: i) the size of bid-ask spreads are positively related to the underlying exchange rate volatility; ii) the magnitude of the dependence on underlying volatility increases as tick volume increases; and iii) the size of the bid-ask …
Quasi-Option Value Under Strategic Interactions, Tomoki Fujii, Ryuichiro Ishikawa
Quasi-Option Value Under Strategic Interactions, Tomoki Fujii, Ryuichiro Ishikawa
Research Collection School Of Economics
We consider a simple two-period model of irreversible investment under strategic interactions between two players. In this setup, we show that the quasi-option value may cause some conceptual difficulties. In case of asymmetric information, decentralized investment decisions fail to induce first-best allocations. Therefore a regulator may not be able to exercise the option to delay the decision to develop. We also show that information-induced inefficiency may arise in a game situation and that under certain assumptions inefficiency can be eliminated by sending asymmetric information to the players, even when the regulator faces informational constraints. Our model is potentially applicable to …
Monetary Policy In Singapore And The Global Financial Crisis, Hwee Kwan Chow, Peter Wilson
Monetary Policy In Singapore And The Global Financial Crisis, Hwee Kwan Chow, Peter Wilson
Research Collection School Of Economics
Prior to the crisis the consensus amongst central bankers in advanced economies was that price stability, in the form of low and stable price inflation, was a top priority for monetary policy and could best be achieved by targeting interest rates (usually overnight) or monetary aggregates, such as Narrow Money (M1) and Broad Money (M2). Liquidity in the banking system could be flexibly adjusted on a daily basis through open market operations to increase or decrease the monetary base which would be transmitted to the rest of the economy through financial intermediation. Financial markets would then adjust longer-term interest rates …
Impact Of Remittances On Schooling In The Philippines: Does The Relationship To The Household Head Matter?, Tomoki Fujii
Impact Of Remittances On Schooling In The Philippines: Does The Relationship To The Household Head Matter?, Tomoki Fujii
Research Collection School Of Economics
The remittance have emerged as one of the most important sources of international flows. In the Philippines, the amount of remittance receipts has more than doubled over a decade since early 1990s. As a result, the way remittances are used has become extremely important for economic development. Unlike the previous studies, we allow for the potential heterogeneity in the impact of remittances across various relationships to the head of household and take into account the potential negative effects of being guarded by someone other than the parents. We find that the impact of remittances on schooling is generally positive and …
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.
