Thinking Local With Original Data In Ai And Machine Learning Research, David G. Taylor, Robert Mccloud

WCBT Working Papers

Sacred Heart University spent significant funds to establish an AI lab. Initially there is no ongoing research and no real plan for a research agenda. This paper details how the Jack Welch College of Business and Technology created and implemented an active meaningful research plan. It involves two key elements: thinking local and using business connections to foster active, impactful research. Surrounding communities, business connections, area environment, and other Sacred Heart University departments all played a part. The research plan also identifies a specific issue in working with local and business contact sources: the AI researcher almost never gets data …

The Price Of Independence In An Echo Chamber With Dependence Ambiguity, Lorán Chollete, Michael Klass, Victor De La Peña

WCBT Working Papers

How much should we pay to remove the interdependence of biased information sources? This question is relevant in both statistics and political economy. When there are many information sources or variables, their dependence may be unknown, which creates multivariate ambiguity. One approach to answer our leading question involves use of decoupling inequalities from probability theory. We present a new inequality, designed to cope with this question, which holds for any type of dependence across information sources. We apply our method to a simple formalization of a political echo chamber. For a given set of marginal information, this bound is the …

Tracking Errors Of Exchange Traded Funds And Index Funds, Rupendra Paliwal

WCBT Working Papers

Exchange traded funds (ETF) are one of the recent financial innovations widely viewed as significantly better investments than mutual funds given their lower fee structure and tax efficiency. Individual investors are increasingly using ETFs tracking most popular stock indices to achieve their investment goals. In some cases, investors are using these ETFs to replace index mutual funds in their long-term portfolios. Thus, it is important to compare the performance of widely held ETFs and index funds in terms of their ability to consistently track the underlying index. Another interesting research question is whether tracking errors of these two investment vehicles …

How Does Bad And Good Volatility Spill Over Across Petroleum Markets?, Jozef Barunık, Evžen Kočenda, Lukas Vacha

WCBT Working Papers

We detect and quantify asymmetries in volatility spillovers using the realized semivariances of petroleum commodities: crude oil, gasoline, and heating oil. During the 1987–2014 period we document increasing spillovers from volatility among petroleum commodities that substantially change after the 2008 financial crisis. The increase in volatility spillovers correlates with the progressive financialization of the commodities. In terms of asymmetries in spillovers we show that periods of increasing crude oil prices strongly correlate with dominating spillovers due to bad volatility. Overall, bad volatility due to negative returns spills over among petroleum commodities to a much larger extent than good volatility due …

Teaching The Catholic Intellectual Tradition Through An Experiential Learning Program, Susan T. Dinnocenti, Maria Lizano-Dimare, Khawaja Mamun, Rupendra Paliwal

WCBT Working Papers

A Catholic University has a specific mission of preserving, transmitting and developing the Catholic Intellectual Tradition. This paper proposes an experiential learning program to support this mission of the catholic universities. This program aims to provide integrated and practical learning of fundamental moral values of catholic intellectual tradition and issues related to social justice while developing the critical and analytical thinking through exposure to real world problems, their possible solutions and a personal reflection. In this paper, we use a microfinance program in an underdeveloped country as the premise for the experiential learning program specifically for business students. Moreover, the …

Sovereign Default Risk In The Euro-Periphery And The Euro-Candidate Countries, Hubert Gabrisch, Lucjan T. Orlowski, Toralf Pusch

WCBT Working Papers

This study examines the key drivers of sovereign default risk in five euro area periphery countries and three euro-candidates that are currently pursuing independent monetary policies. We argue that the recent proliferation of sovereign risk premiums stems from both domestic and international sources. We focus on contagion effects of external financial crisis on sovereign risk premiums in these countries, arguing that the countries with weak fundamentals and fragile financial institutions are particularly vulnerable to such effects. The domestic fiscal vulnerabilities include: economic recession, less efficient government spending and a rising public debt. External ‘push’ factors entail increasing liquidity- and counter-party …

Forecasting And Stress-Testing The Risk-Based Capital Requirements For Revolving Retail Exposures, Kwamie Dunbar

WCBT Working Papers

This paper presents a tractable and empirically sound technique for generating stressed probabilities of default (PDs) which are then used to derive loss rates for the provisioning of a bank’s risk-based capital. This work is in response to the recent regulatory findings attributed to the Supervisory Capital Assessment Program (SCAP) stress tests of 2009 which revealed weaknesses in the existing regulatory and economic capital approaches. The SCAP projected losses of approximately $82.4 Billion in banks’ credit card portfolios for 2010, highlighting the need for better forecasting and stress testing of revolving retail exposures.

This study proposes a timely model that …

Invisible Discrimination: Employers & Social Media Sites, Richard L. Pate

WCBT Working Papers

With the advent and popularity of social networks sites, the boundaries of the relationship between the employer-employee/prospective employee have stretched well beyond the work-place and work-hours. Predictably, this relationship expansion has led to unchartered adversarial scenarios between the respective parties. Unfortunately, in this new, vibrant cyber world, traditional employment law considerations are struggling for deference and rumination. Notwithstanding this ostensible indifference, each phase of the relationship is heavily impacted by social network media. Applicant recruitment, information gathering and applicant selection stand to be impacted by the social network communications made by employees or prospective employees. This article examines whether present …

Transformational Teams And Their Impact On Customer Satisfaction At One Firm, Timothy J. Crader D.B.A., Stephen M. Brown Ed, D.

WCBT Working Papers

This study examined the relationships between core selling teams (CSTs) and customer satisfaction within the mission critical power design industry. The literature indicates that CSTs, which are considered a state of the art sales model, deserved further research. The SERVQUAL survey was used to measure customer satisfaction with Company X’s most strategic customers. The difference in customer satisfaction for customers serviced by CSTs and traditional sales personnel were compared. The investigation found support indicating that a CST approach had a positive relationship to increased customer satisfaction levels. Based on the results of the study, it is recommended that sales leaders …

The Status Of Recognition And Enforcement Of Judgments In The European Union, Michael D. Larobina, Richard L. Pate

WCBT Working Papers

International trade and the free movement of people are inevitably followed by legal disputes. Such litigants require an efficient and predictable dispute resolution mechanism capable of handling cases between diverse nationals. An essential part of such mechanism is a clearly defined process of judgment enforcement across national boundaries. In the past several decades, the European Union (“EU”) has necessarily addressed judgment enforcement across the boundaries of its member nations (“Member States”). Citizens of the EU need to prosecute and defend their legal rights in their home and in other EU member states. Presently, the EU is, again, considering such issues …

Cross Cultural Variables: Evaluating Employee Attitudes Across Four Regions Of Asia, Europe, North And Latin America, Martin Brockerhoff, Jeanine K. Andreassi Ph.D.

WCBT Working Papers

There has been an explosion of businesses moving operations overseas, setting up international joint ventures and establishing multinational enterprises. This trend has led organizational researchers as well as corporations to explore the implications of cultural differences in managing a workforce. Can the same Western management practices be used as effectively with employees in Asia as in North America? Does the application of Western management principles in multinationals affect aspects of job satisfaction in non-Western countries? This poster reports the findings from two exploratory analyses on the relationship between job attitudes and the geographic/cultural setting of business organizations. The first analysis …

Effectively Hedging The Interest Rate Risk Of Wide Floating Rate Coupon Spreads, Thomas Schröder, Kwamie Dunbar

WCBT Working Papers

Bond issuers frequently immunize/hedge their interest rate exposure by means of interest rate swaps (IRS). The receiving leg matches all bond cash-flows, while the pay leg requires floating rate coupon payments of form LIBOR + a spread. The goal of hedging against interest rate risk is only achieved in full if the present value of this spread is zero. Using market data we show that under a traditional IRS hedging strategy an investor could still experience significant cash flow losses given a 1% shift in the underlying benchmark yield curve.

We consider the instantaneous interest-rate risk of a bond portfolio …

Single And Multiple Interruptions Increase Task Performance Time, But Don't Affect Stress, Pressure Or Flow, Maureen A. Conard, Robert F. Marsh

WCBT Working Papers

We compared task performance time and psychological reactions for uninterrupted, single interrupted, and multiple interrupted conditions. For 110 undergraduates, those who were uninterrupted while completing a jigsaw puzzle were 26% faster than the single interruption, and 30% faster than the multiple interruption conditions. Single and multiple interruption conditions were not significantly different. Participants in the multiple interruption condition felt more stress than those in the uninterrupted condition, although stress levels were low in both conditions. Perceptions of time pressure and flow were not different across conditions. Performance on the interrupting task (a word search puzzle) was not significantly different across …

The Extreme Risk Problem For Monetary Policies Of The Euro-Candidates Countries, Hubert Gabrisch, Lucjan T. Orlowski

WCBT Working Papers

We argue that monetary policies in euro-candidate countries should also aim at mitigating excessive instability of the key target and instrument variables of monetary policy during turbulent market periods. Our empirical tests show a significant degree of leptokurtosis, thus prevalence of tail-risks, in the conditional volatility series of such variables in the euro-candidate countries. Their central banks will be well-advised to use both standard and unorthodox (discretionary) tools of monetary policy to mitigate such extreme risks while steering their economies out of the crisis and through the euroconvergence process. Such policies provide flexibility that is not embedded in the Taylor-type …

Interest Rate Convergence In The Euro-Candidate Countries: Volatility Dynamics Of Sovereign Bond Yields, Hubert Gabrisch, Lucjan Orlowski

WCBT Working Papers

We advocate a dynamic approach to monetary convergence to a common currency that is based on the analysis of financial system stability. Accordingly, we test empirically volatility dynamics of the ten-year sovereign bond yields of the 2004 EU accession countries in relation to the eurozone yields during the January 2, 2001- January 22, 2009 sample period. Our results show a varied degree of bond yield co-movements, the most pronounced for the Czech Republic, Slovenia and Poland, and weaker for Hungary and Slovakia. However, since the EU accession, we find some divergence of relative bond yields. We argue that a ‘static’ …

Tobacco Politics And Electoral Accountability In The United States, Per G. Fredriksson, Khawaja Mamun

WCBT Working Papers

This paper investigates whether reputation-building strategies guide U.S. governors’ state cigarette tax choices, and whether the federal cigarette tax influences such behavior. Using 1975-2000 data, we find evidence that governors in states with relatively important agricultural tobacco production and tobacco manufacturing, and which are densely populated by smokers, appear prone to reputation-building. Moreover, lame ducks are more prone to raise the state cigarette tax the lower the federal tax.

Gubernatorial Reputation And Vertical Tax Externalities: All Smoke, No Fire?, Per G. Fredriksson, Khawaja Mamun

WCBT Working Papers

This paper investigates whether reputation-building strategies guide U.S. governors’ responses to changes in federal cigarette taxes (i.e. vertical tax interactions). Using 1975-2000 state cigarette tax data, we find that reputation-building strategies affect the nature of vertical tax externalities. Lame duck governors exhibit a more negative response to changes in the federal cigarette tax. Thus, by reducing the state tax base and by causing a decline in the state tax, an increase in the federal tax rate reduces state tax revenues in states headed by lame ducks.

An Investigation Into The Relationship Between Gender Perception Of Computing, Computer Self-Efficacy, And Computer Anxiety: A Comparison Study Between Chinese Females And American Females, Kittipong Laosethakul

WCBT Working Papers

It is believed that the perception that computing is a male domain has discouraged American women to participate in computing fields. Like the U.S., computing is also dominated by men in China. However, unlike the U.S., information technology is ranked the highest compared with other industries in term of career choices for Chinese female university graduates. This study investigates how computer anxiety and computer self-efficacy influence gender perception toward computing of Chinese female in comparison to American female. One of the findings indicated computer anxiety directly impacts gender perception toward computing of females in both cultures.
