The Long-Run Performance Of U.S. Firms Pursuing Ipos In Foreign Markets, Robert N. Killins, Peter V. Egly

School of Economics and Finance Faculty Publications

Purpose

The purpose of this paper is to investigate the long-run performance of a unique set of US domiciled firms that have bypassed the US capital markets in pursuit of their initial public offering (IPO) overseas. Additionally, this paper then tests the popular underwriter prestige impact and the window of opportunity hypothesis on this unique subset of IPOs.

Design/methodology/approach

Using a sample of foreign and purely domestic IPOs made by US firms from 2000 to 2011, this study investigates the long-term performance, one-, two- and three-year by using two measures (buy-and-hold return and cumulative abnormal returns) to test the long-run …

Inference In Continuous Systems With Mildly Explosive Regressors, Ye Chen, Peter C. B. Phillips, Jun Yu

Research Collection School Of Economics

New limit theory is developed for co-moving systems with explosive processes, connecting continuous and discrete time formulations. The theory uses double asymptotics with infill (as the sampling interval tends to zero) and large time span asymptotics. The limit theory explicitly involves initial conditions, allows for drift in the system, is provided for single and multiple explosive regressors, and is feasible to implement in practice. Simulations show that double asymptotics deliver a good approximation to the finite sample distribution, with both finite sample and asymptotic distributions showing sensitivity to initial conditions. The methods are implemented in the US real estate market …

Identifying Latent Group Structures In Nonlinear Panels, Wuyi Wang, Liangjun Su

Research Collection School Of Economics

We propose a procedure to identify latent group structures in nonlinear panel data models where some regression coefficients are heterogeneous across groups but homogeneous within a group and the group number and membership are unknown. To identify the group structures, we consider the order statistics for the preliminary unconstrained consistent estimators of the regression coefficients and translate the problem of classification into the problem of break detection. Then we extend the sequential binary segmentation algorithm of Bai (1997) for break detection from the time series setup to the panel data framework. We demonstrate that our method is able to identify …

Business Time Sampling Scheme With Applications To Testing Semi-Martingale Hypothesis And Estimating Integrated Volatility, Yingjie Dong, Yiu Kuen Tse

Research Collection School Of Economics

We propose a new method to implement the Business Time Sampling (BTS) scheme for high-frequency financial data. We compute a time-transformation (TT) function using the intraday integrated volatility estimated by a jump-robust method. The BTS transactions are obtained using the inverse of the TT function. Using our sampled BTS transactions, we test the semi-martingale hypothesis of the stock log-price process and estimate the daily realized volatility. Our method improves the normality approximation of the standardized business-time return distribution. Our Monte Carlo results show that the integrated volatility estimates using our proposed sampling strategy provide smaller root mean-squared error.

Cultural Preferences In International Trade: Evidence From The Globalization Of Korean Pop Culture, Pao-Li Chang, Iona Hyojung Lee

Research Collection School Of Economics

The Korean pop culture (TVdramas and K-pop music) has grown immensely popular across the globe over thepast two decades. This paper analyzes its impacts on international trade. We compilea cross-country panel dataset of South Korea's TV show exports to over 150countries for the period of 1998{2014. These variations in exposure to Koreanpop cultures are used to identify changes in consumer preferences for Koreanmerchandise across time, countries, and products (at the HS 4-digit level).First, we find that more Korean TV show exports significantly increase Koreanexports of goods for women, while the effects are much smaller on men'smerchandise. This strongly supports the …

Bayesian Analysis Of Bubbles In Asset Prices, Andras Fulop, Jun Yu

Research Collection School Of Economics

We develop a new asset price model where the dynamic structure of the asset price, after the fundamental value is removed, is subject to two different regimes. One regime reflects the normal period where the asset price divided by the dividend is assumed to follow a mean-reverting process around a stochastic long run mean. This latter is allowed to account for possible smooth structural change. The second regime reflects the bubble period with explosive behavior. Stochastic switches between two regimes and non-constant probabilities of exit from the bubble regime are both allowed. A Bayesian learning approach is employed to jointly …

Distinction Between Primary And Secondary Mitochondrial Disease, Niyazov D. M

Manipal Journal of Medical Sciences

Mitochondrial disease refers to a large spectrum of disorders involving defective cellular energy production. Primary mitochondrial disease (PMD) is diagnosed clinically and by genetic testing of mitochondrial and nuclear DNA. However, many disorders have the ‘mitochondrial’ phenotype without an identifiable genetic defect. Even muscle biopsy can be markedly abnormal either due to a PMD or a non-mitochondrial disorder (NMD) affecting mitochondria and giving rise to secondary mitochondrial dysfunction (SMD). Many patients can have clinical signs of mitochondrial dysfunction based on their phenotype, biomarkers, imaging, and muscle biopsy. In these cases, it is often tempting to assign a patient’s phenotype to …

Sleeve Resection – Carcinoma External Auditory Canal, Gangwar Navneeta, Vyas Pratibha, Joshi Narayani

Manipal Journal of Medical Sciences

Malignancies of external auditory canal (EAC) are uncommon. One per million is the annual incidence. Most common is squamous cell carcinoma, followed by adenoid cystic, basal cell carcinoma and melanoma. Consensus on treatment modality may vary due to the rarity of the tumour. We present a case of squamous cell carcinoma of EAC limited to the cartilaginous part l, presenting with intermittent ear discharge for many months. A sleeve resection with safety margin was done and a split-thickness skin grafting was done for reconstruction. There was no immediate complication and no evidence of any recurrence even after one and a …

Comparing Two Alternate Assessments: Dynamic Learning Maps And Multi-State Alternate Assessment, Dana N. Sir

Seton Hall University Dissertations and Theses (ETDs)

In 2001 under No Child Left Behind, states were required to create an alternate assessment for students with significant cognitive disabilities using alternate achievement standards. In 2003, all states had created an alternate assessment. All fifty states independently developed, implemented, and revised their alternate assessments. By 2014, Dynamic Learning Map (DLM) and Multi-State Alternate Assessments (MSAA) (formerly National Center and State Collaborative)––two alternate assessments developed through consortiums consisting of state departments, universities, and organizations using federal funding––were created. At the time of this study, the DLM and MSAA were used by approximately 49% of states for their alternate assessment. This …

Effects Of Direction Time Constraints And Walking Speed On Turn Strategies And Gait Adaptations In Healthy Older And Young Adults, Dennis Torre

Seton Hall University Dissertations and Theses (ETDs)

Hip fractures can be life-threatening, debilitating, and costly. The odds for hip fracture increases from impact of sideways falls. While turning has been strongly associated with hip fracture & sideways falls, the distinction between the risks for walking-turns as opposed to low-velocity in-place turning is not clear. The present study sought to fill a gap as previous research had not compared walking-turn performance in young & healthy older adults at low-fall risk within the same study and response-conditions of speed interacting with direction-cue time constraints. Spatial-temporal variables representative of AP braking/propulsion (i.e. stride-length & speed) & ML stability (left/right H-H …

Padres Activos, Ninos Creativos/Active Parents, Creative Children 2017, Judith Aguilera

Capstone Projects and Master's Theses

There is a high percentages of monolingual Spanish speaking parents who do not know how to navigate the school systems, especially in the East Salinas. Therefore, it is very difficult for parents to collaborate with schools without having the basic information that each parent must have in order to navigate the school systems. I did my capstone project at Building Healthy Communities in Salinas, CA. In 2009 Building Healthy Communities became one of The California Endowment’s 14 initiatives. BHC is a ten-year initiative with four focus campaigns where it collaborates directly with different non-profit organizations. BHC is committed to improve …

Pbis: Moving Beyond A Focus On Behavior To Relationships, Flor Gomez

Capstone Projects and Master's Theses

School-Wide Positive Behavioral Intervention and Supports (SW-PBIS or PBIS) is a classroom management system that has become increasingly popular in our K-12 educational systems. PBIS was originally created for special needs students and it is now being enforced in schools with a large number of minority student populations. This classroom management method relies on a token rewards system that focuses on reinforcing positive behavior in the classroom. Issues with this classroom management system encompass it being a form of exclusionary discipline, a student conditioning system, and not a culturally grounded and/or responsive system. For this Capstone Project, teachers and students …

Esl And Ell Program Effectiveness: Providing Academic Success For Students, Maria Gonzalez-Herrera

Capstone Projects and Master's Theses

The aim of this study was to examine the effectiveness of English as a Second Language and English Language Learners—ESL and ELL respectively—programs in helping students whose native language is not English achieve academic success in school. The general issue with these programs is that more often than not, students whose native language is not English are placed in separate classrooms from their peers, which leads to an academic disadvantage because the focus is on language acquisition. This does not provide other forms of long-term knowledge that will help the students. In other words, ESL and ELL programs are efficient …

Slipping Through The Cracks: A Look Into Special Education Referrals, Courtney Musselman

Capstone Projects and Master's Theses

Special Education is offered in many schools today and more and more students are being referred to this type of education. For this capstone project three local special education teachers were interviewed about the referral process and what could be done to improve it. This is an important issue because many students are slipping through the cracks when it comes to be identified and others are being overly identified. The referral process is important because it provides students with an equal opportunity for education. Findings from the interviews and information from a relevant literature review were used to develop an …
