Targeted Killing: Self-Defense, Preemption, And The War On Terrorism, Thomas Byron Hunter May 2009

Targeted Killing: Self-Defense, Preemption, And The War On Terrorism, Thomas Byron Hunter

Journal of Strategic Security

This paper assesses the parameters and utility of “targeted killing” in combating terrorism and its role within the norm of state self-defense in the international community. The author’s thesis is that, while targeted killing provides states with a method of combating terrorism, and while it is “effective” on a number of levels, it is inherently limited and not a panacea. The adoption and execution of such a program brings with it, among other potential pitfalls, political repercussions. Targeted killing is defined herein as the premeditated, preemptive, and intentional killing of an individual or individuals known or believed to represent a …


Al-Qaeda In The Lands Of The Islamic Maghreb, Gregory A. Smith May 2009

Al-Qaeda In The Lands Of The Islamic Maghreb, Gregory A. Smith

Journal of Strategic Security

This paper is organized into four chapters that focus on the terrorist group Al Qaeda in the Lands of the Islamic Maghreb (AQIM). The four chapters examine different facets of the collective environment that have allowed AQIM to succeed and even thrive at times. The first chapter begins with Algeria’s war of independence with the French. The second chapter focuses on the nomadic Tuareg people. It seeks to show how the Tuaregs were deprived by French occupiers and how European colonization cost the Tuaregs access to vital trade routes used for centuries. The third chapter will very briefly examine Algeria’s …


Fragility: The Next Wave In Critical Infrastructure Protection, Allan Mcdougall May 2009

Fragility: The Next Wave In Critical Infrastructure Protection, Allan Mcdougall

Journal of Strategic Security

In North America today, we are about to embark on a significant effort to repair, or even upgrade, many aspects of our infrastructure. Many of these efforts are linked to economic recovery packages. Others are based on sheer need. The challenge for decision makers and planners involves ensuring that scarce economic resources are put to their best use. Understanding the concept of fragility plays a pivotal part in reaching that understanding.Fragility, like many other systems—particularly Information Technology (IT ) systems—works on the concept of subjects and objects. Subjects are those entities that seek to exploit the services (or capacity) offered …

International Evidence On Analyst Monitoring And Earnings Management: The Roles Of Corporate Disclosure And National Culture, Soongsoo Han, Tony Kang, Gerald Lobo, Yong Keun Yoo Jan 2009

International Evidence On Analyst Monitoring And Earnings Management: The Roles Of Corporate Disclosure And National Culture, Soongsoo Han, Tony Kang, Gerald Lobo, Yong Keun Yoo

Research Collection School Of Accountancy

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 …


Has The Introduction Of Bookbuilding Increased The Efficiency Of China's Ipo Pricing?, Jiehui Fei Jan 2009

Has The Introduction Of Bookbuilding Increased The Efficiency Of China's Ipo Pricing?, Jiehui Fei

Dissertations and Theses Collection (Open Access)

Book-building is commonly adopted in global primary markets and regarded as the most efficient pricing method for accurate IPO pricing by literatures. China has introduced book-building in 2005 to increase IPO pricing accuracy and the capabilities of domestic institutional investors. However, with the current IPO data from China, I find the level of under-pricing has unexpectedly increased after book-building, which is against the empirical studies of a few domestic papers. Secondly, there's some evidence that with better information disclosure from issuer-side through book-building process, the signaling and ex-ante uncertainty effect that previously caused under-pricing has been reduced. But there're unique …


Icworld: An Mmog-Based Approach To Analysis, Kimberly Gill, David Rolston, Wyatt Wong, Robert Pietrusko Nov 2008

Icworld: An Mmog-Based Approach To Analysis, Kimberly Gill, David Rolston, Wyatt Wong, Robert Pietrusko

Journal of Strategic Security

Intelligence analysts routinely work with "wicked" problems—critical,time-sensitive problems where analytical errors can lead to catastrophic consequences for the nation's security. In the analyst's world, important decisions are often made quickly, and are made based on consuming, understanding, and piecing together enormous volumes of data. The data is not only voluminous, but often fragmented, subjective, inaccurate and fluid.Why does multi-player on-line gaming (MMOG) technology matter to the IC? Fundamentally, there are two reasons. The first is technological: stripping away the gamelike content, MMOGs are dynamic systems that represent a physical world, where users are presented with (virtual) life-and-death challenges that can …


Short Takes: Intelligence-Service Psychology: A German Perspective, Sven Max Litzcke, Helmut Müller-Enbergs Nov 2008

Short Takes: Intelligence-Service Psychology: A German Perspective, Sven Max Litzcke, Helmut Müller-Enbergs

Journal of Strategic Security

To date, four German volumes in the series "Intelligence-Service Psychology" (Nachrichtendienstpsychologie) have been published. These volumes generated interest in both the German and non-German speaking communities. It was therefore decided to translate some of the basic articles of the series into English (Litzcke, Müller-Enbergs & Ungerer, 2008), making them accessible to a wider range of readers. This article contains abbreviated versions of the articles in the book.


Research Note: Using The Iterate And Dots Databases, Peter A. Flemming, Edward Mickolus, Todd Sandler Nov 2008

Research Note: Using The Iterate And Dots Databases, Peter A. Flemming, Edward Mickolus, Todd Sandler

Journal of Strategic Security

For more than three decades, Vinyard Software's two ITERATE (International Terrorism: Attributes of Terrorist Events) datasets have set the standard in events research for terrorism researchers. It has recently been supplemented by the DOTS (Data on Terrorist Subjects) biographies project, which covers all terrorists, supporters, and other individuals mentioned in the ITERATE project.

Dividing Up Intelligence Education, Robert Clark, Ph.D Nov 2008

Dividing Up Intelligence Education, Robert Clark, Ph.D

Journal of Strategic Security

At this year's annual conference of the International Association for Intelligence Education (IAFIE) in Monterey, CA, the keynote speaker posed the question, "How much do you need intelligence education outside the beltway?" Which led to a second question discussed during the conference: "What should such education look like?" In short, what should we be teaching in universities? What should we leave to the intelligence community as training? And what could be done in either or both settings? The first question of any educational effort is:What are we preparing students for?


Strategic Security As A New Academic Discipline, Sheldon Greaves, Ph.D Nov 2008

Strategic Security As A New Academic Discipline, Sheldon Greaves, Ph.D

Journal of Strategic Security

The creation of Henley-Putnam University was an effort to create an academic institution for the purpose of offering degree programs in intelligence management, counterterrorism, and personal protection; subjects that arguably did not exist as academic disciplines when the school was conceived. The experience of two of the co-founders of the school, Nirmalya Bhowmick and Dr. Michael Corcoran, indicated that the training of officers tasked with vital security and intelligence work was carried out by partnering young officers with a training officer to help the new officer learn on the job. The effectiveness of this training depended to a great extent …

Behavioral Explanations Of Trading Volume And Short-Horizon Price Patterns: An Investigation Of Seven Asia-Pacific Markets, David K. Ding, Thomas H. Mclnish, Udomsak Wongchoti Jun 2008

Behavioral Explanations Of Trading Volume And Short-Horizon Price Patterns: An Investigation Of Seven Asia-Pacific Markets, David K. Ding, Thomas H. Mclnish, Udomsak Wongchoti

Research Collection Lee Kong Chian School Of Business

We investigate whether behavioral postulations offer any implicit explanation of the country-varying relation between trading volume and price pattern among short-horizon winners/losers in seven Pacific-Basin markets during the period 1990 to 2000. Our findings lend credence to the Lee and Swaminathan [Lee, C. and Swaminathan, B., 2000. Price momentum and trading volume, Journal of Finance 55, 2017-2069.] Momentum Life Cycle explanation that high (low) volume winners (losers) are more likely to experience price reversals, whereas high (low) volume losers (winners), price momentum, in the subsequent period. This observation is especially pronounced in Hong Kong. Other models such as those based …


Liquidity Distribution In The Limit Order Book On The Stock Exchange Of Thailand, Nuttawat Visaltanachoti, Charlie Charoenwong, David K. Ding Mar 2008

Liquidity Distribution In The Limit Order Book On The Stock Exchange Of Thailand, Nuttawat Visaltanachoti, Charlie Charoenwong, David K. Ding

Research Collection Lee Kong Chian School Of Business

The liquidity distribution, or the shape of the limit order book, influences trading behavior and choice of order submission by public liquidity suppliers. The present study seeks to discover whether liquidity providers are concerned about being picked off by informed traders, and whether they are less willing to supply liquidity at the market or demand higher price spreads. The results show that liquidity at the market is a small portion of total liquidity, and that firm size, minimum tick size, volatility, and trading volume play significant roles in determining the liquidity distribution within an order book.


Investment Patterns In Singapore's Central Provident Fund System, Benedict S. K. Koh, Olivia S. Mitchell, Toto Tanuwidjaja, Joelle Fong Mar 2008

Investment Patterns In Singapore's Central Provident Fund System, Benedict S. K. Koh, Olivia S. Mitchell, Toto Tanuwidjaja, Joelle Fong

Research Collection Lee Kong Chian School Of Business

Rising elderly life expectancies imply the need to accumulate sufficient savings for retirement. This paper investigates the role of recent changes in the investment menu of the Singaporean Central Provident Fund (CPF) system. Our research explores the investment patterns of CPF participants and articulates their implications for policymakers. We find that most investors use their money for housing purchase and default the remainder to the CPF investment pool. The bulk of non-housing saving sits in bank accounts paying a low return. A fraction of workers does elect outside investment products, with high-income earners and males taking more risk than low-income …


Offshore Financial Havens: Their Role In International Capital Flows, Zhixiang Sun Jan 2008

Offshore Financial Havens: Their Role In International Capital Flows, Zhixiang Sun

Dissertations and Theses Collection (Open Access)

The purpose of this paper is to study the role of offshore financial havens in international capital flows. We examine the effects of being a tax haven, a money laundering centre or an offshore financial centre (OFC), which often overlap. We want to see whether these places are used as entrepots (which means temporary storage for funds) or as investment places or both. We mainly use two complementary data sets: bilateral cross-border asset holding and financial intermediation. One is a stock variable and the other one is a flow variable. We apply the gravity model to bilateral cross-border asset holding …


Rolling Adf Tests: Detecting Rational Bubbles In Greater China Stock Markets, Peng Huang Jan 2008

Rolling Adf Tests: Detecting Rational Bubbles In Greater China Stock Markets, Peng Huang

Dissertations and Theses Collection (Open Access)

Following Phillips, Wu and Yu (2007), this paper extends their bubble detecting work to several Greater China stock markets. Two alternative bubble detecting methods, the forward recursive ADF tests raised by Phillips et al. (2007) and the modified version, forward rolling ADF tests, are implemented and compared. Monte Carlo simulations are performed to determine the critical values of the ADF statistic under different sample size. Empirical results demonstrate that only rolling ADF tests are successful in detecting rational bubbles by overcoming the problem of periodically collapsing bubble. As we have expected, bubbles in China Mainland stock market are detected. Out …


Stock Markets And Income Inequality: A Cross-Country Study, Elizabeth Mathew Jan 2008

Stock Markets And Income Inequality: A Cross-Country Study, Elizabeth Mathew

Dissertations and Theses Collection (Open Access)

This paper conducts a comprehensive analysis to understand how stock market ratios affect net income inequality. The study of how finance impacts income distribution is relevant as the income distribution of a nation influences savings decisions, resource allocation, innovation incentives and public policy and hence impacts the process of economic development. Using a cross-sectional data set of 68 countries and panel data set of 61 countries from 1975 to 2005, I apply cross-sectional OLS and panel regressions to look at how stock market size, liquidity, and activity impact income inequality. While stock market size is found to strongly impact income …


Flow-Performance Relationship And Tournament Behavior In The Mutual Fund Industry, Baoling Ma Jan 2008

Flow-Performance Relationship And Tournament Behavior In The Mutual Fund Industry, Baoling Ma

Dissertations and Theses Collection (Open Access)

In this paper, we interpret the flow-performance relationship as an incentive scheme implicitly given to mutual fund managers by mutual fund investors. We show that the flow-performance relationship varies not only with economic activity but also across fund attributes. We provide evidence that the degree of convexity of the flow-performance relationship has a positive effect on the magnitude of tournament behavior. Different from the conventional tournament hypothesis, we show that although the convexity of the flow-performance relationship does produce implicit incentives for fund managers to modify risk-taking behavior as a function of their prior performance, whether or not the mid-year …


Test For Infinite Variance In Stock Returns, Xian Ning Yan Jan 2008

Test For Infinite Variance In Stock Returns, Xian Ning Yan

Dissertations and Theses Collection (Open Access)

The existence of second order moment or the finite variance is a commonly used assumption in financial time series analysis. We examine the validation of this condition for main stock index return series by applying the extreme value theory. We compare the performances of the adaptive Hill's estimator and the Smith's estimator for the tail index using Monte Carlo simulations for both i.i.d data and dependent data. The simulation results show that the Hill's estimator with adaptive data-based truncation number performs better in both cases. It has not only smaller bias but also smaller MSE when the true tail index …


The Change In Corporate Transparency Of Korean Firms After The Asian Financial Crisis: An Analysis Using Analysts' Forecast Data, Jinho Chang, Young Jun Cho, Hyun-Han Shin Nov 2007

The Change In Corporate Transparency Of Korean Firms After The Asian Financial Crisis: An Analysis Using Analysts' Forecast Data, Jinho Chang, Young Jun Cho, Hyun-Han Shin

Research Collection School Of Accountancy

Using analysts' forecast error and forecast dispersion of firms covered by the I/B/E/S database, this study examines the change in information asymmetry of Korean firms around the financial crisis of 1997. Results show that the information asymmetry of Korean firms is lower after the financial crisis than before, implying that corporate transparency did, in effect, improve with the change in business environment. In addition, this study finds that chaebol firms have higher information asymmetry than non-chaebol firm, and also that the corporate transparency improvement of chaebol firms is not higher than that of non-chaebol firms in the post-crisis period despite …


Periodically Collapsing Bubbles In The Asian Emerging Stock Markets, Ako Doffou Jan 2007

Periodically Collapsing Bubbles In The Asian Emerging Stock Markets, Ako Doffou

WCBT Faculty Publications

This paper investigates empirically the existence of periodically collapsing bubbles in the Asian emerging stock markets using the Enders-Siklos (2001) momentum threshold autoregressive model. As explained in Bohl (2003), this non-linear time series technique can be used to analyze bubble driven run-ups in stock prices followed by a crash in a non- cointegration framework with asymmetric adjustment. This technique offers a more potent insight in the stock prices behavior than can possibly be obtained using conventional non-cointegration tests. The empirical findings for ten Asian emerging stock markets from 1993 to 2005 refute the bubble hypothesis.


Abnormal Trading Volume, Stock Returns And The Momentum Effects, Ying Zheng Jan 2007

Abnormal Trading Volume, Stock Returns And The Momentum Effects, Ying Zheng

Dissertations and Theses Collection (Open Access)

This paper intends to study the intermediate-term momentum and long-term reversal of stock prices by investigating the informational role of unusual trading volume for winner and loser stocks. I argue that unusual trading volume has different implications for winner and loser stocks. Specifically, high trading volume for losers is driven by purchases made by informed investors; while high trade volume for winners could be driven by either information or representativeness bias or both. The arguments are tested in the paper by showing that in the short run, losers/winners with high abnormal trading volume outperform losers/winners with low abnormal trading volume; …


Information Value Of Credit Ratings In Asia Ex-Japan Markets, Chen Zhou Jan 2006

Information Value Of Credit Ratings In Asia Ex-Japan Markets, Chen Zhou

Dissertations and Theses Collection (Open Access)

This study investigates the information value of credit ratings by exploring the relationship between ratings and security price. Unlike previous studies, we concentrate on the major markets ex-Japan in Asia. We begin with an investigation of rating reclassification as well as credit watch placement events by three leading international rating agencies. We show that markets with differing level of sophistication behave differently. Specifically, South Korea and Hong Kong are found to respond in a similar manner. Indonesia shows possible ign of information leakage. In the cases of Malaysia and Thailand, significant and positive equity price responses exist for upgrades, suggesting …


The Impact Of S&P Depository Receipts On The S&P Cash And Futures Market, Andrew J. Economopoulos May 2005

The Impact Of S&P Depository Receipts On The S&P Cash And Futures Market, Andrew J. Economopoulos

Business and Economics Faculty Publications

The introduction of the S&P Depository Receipt (SPDR) in 1993 was a financial innovation that produced several ripple effects in the financial markets. Not only did it allow the small investor to purchase a piece of the S&P 500 Cash Index, it would allow the large investor to utilize the security for arbitrage opportunities with the S&P 500 futures. A theoretical model of arbitrage opportunities utilizing SPDR is developed. The theoretical model provides two outcomes. First, the adoption of the SPDR as an arbitrage tool depends on transaction and liquidity costs and second, the innovation could potentially reduce the traditional …


Is Exchange Risk Priced Beyond Intertemporal Risk?, Ines Chaieb, Stefano Mazzoto, Oumar Sy Mar 2005

Is Exchange Risk Priced Beyond Intertemporal Risk?, Ines Chaieb, Stefano Mazzoto, Oumar Sy

Faculty Articles

Recent conditional tests show that exchange risk is priced in integrated international markets. However, these results are typically obtained assuming that intertemporal risk does not matter. We test an intertemporal international asset-pricing model where the investment opportunity set is dynamic. Using a conditional orthogonalization approach, we investigate whether the exchange risk is priced once the market and intertemporal risks are fully taken into account. We find that, in addition to the market and intertemporal risks, the exchange risk is an important determinant of risk premium. We also find that the intertemporal risk, which is often overlooked in the literature, is …


Corporate Divestitures And Spinoffs In Singapore, Francis Koh, Winston T. H. Koh, Benedict S. K. Koh Mar 2005

Corporate Divestitures And Spinoffs In Singapore, Francis Koh, Winston T. H. Koh, Benedict S. K. Koh

Research Collection Lee Kong Chian School Of Business

This paper discusses the different forms of corporate divestitures, the motives for this corporate activity, and the empirical findings about their economic outcomes. A sample of corporate divestitures is also used to identify the main motivations in the Singapore context. We conclude that divestitures are carried out to achieve operational efficiency and gain incremental profitability and liquidity. Using share price data around the event-dates, we show that announcements of divestitures generally lead to significant increases in the returns of the parent company. The positive abnormal returns are related to the relative size of the divestitures and the computed accounting gains. …
