Threshold Effects In Volatility Spillovers: The Case Of Equity, Bond And Foreign Exchange Markets, Arun Prasath Narayanasamy
Threshold Effects In Volatility Spillovers: The Case Of Equity, Bond And Foreign Exchange Markets, Arun Prasath Narayanasamy
Finance and Real Estate Dissertations - Archive
Most research on volatility spillovers across countries and various asset class returns model volatility as conditional variance and assume a linear relationship in spillovers. The risk measured as conditional variance is modeled as a function of own past innovations and own past conditional variances and fails to include lagged conditional variances from other assets. In this dissertation, for a bivariate set up, I estimate the conditional variance of the second country either as a GARCH (1, 1) or DCC (1, 1) type process. Using the estimated conditional variances, the non-linear or threshold parameter is computed by maximizing the log likelihood …
Measurement Issues In The Capital Asset Pricing Model & Size Effect And Duration, Yongho Seo
Measurement Issues In The Capital Asset Pricing Model & Size Effect And Duration, Yongho Seo
Finance and Real Estate Dissertations - Archive
It has been observed that the value of an asset's beta varies with the frequency of the data used to generate the value, a phenomenon hereafter referred to as "time scale", or simply "scale". If the scale effect is strong enough, then ignoring this phenomenon calls into question studies that rely on comparing beta values. The most notable of these studies is the classification of stocks as "aggressive" or "defensive". I show that such a categorization varies substantially when comparing betas estimated using monthly data versus annual data. Contrary to other studies, betas do not vary monotonically as data scale …

The Moderating Effect Of Instrumental Job Attributes On The Relationship Between A Firm's Perceived Value Of Diversity And Its Organizational Attractiveness, Jason R. Lambert
The Moderating Effect Of Instrumental Job Attributes On The Relationship Between A Firm's Perceived Value Of Diversity And Its Organizational Attractiveness, Jason R. Lambert
Management Dissertations - Archive
Increasingly more firms are targeting both racial and sexual minorities in recruitment ads to attain a diverse work climate. However, the challenge remains of recruiting job seekers without alienating qualified others. Expectancy theory and social identity theory are used to investigate how employee recruitment statements regarding employment-at-will and pay moderate the effect that diversity-supportive recruitment statements have on job seekers' job pursuit intentions and attraction towards a firm. A model is tested that demonstrates an interaction effect between perceived instrumental job attributes and perceived symbolic attributes on the organizational attractiveness of a firm. Implications from the results are discussed, including …
Understanding The Relationship Of Job Embeddedness With Social And Human Capital: The Importance Of Organizational Identification, Aaron R. Moses
Understanding The Relationship Of Job Embeddedness With Social And Human Capital: The Importance Of Organizational Identification, Aaron R. Moses
Management Dissertations - Archive
This dissertation examines organizational identification as a critical moderator of the outcomes of job embeddedness using a survey sample of employees from a hospital in the Southwestern United States. Results suggest that job embeddedness leads employees to develop different types of human and social capital depending on their organizational identification or disidentification. I conclude that employee outcomes are different depending on how employees view their job-embedded situations and argue that job embeddedness be reconceptualized to account for different reactions to job embeddedness based on organizational identification. Implications for researchers and managers are also discussed.

A Late Holocene Meander-Braid Transition Of The Lower Missouri River Valley, Michele Viola Kashouh
A Late Holocene Meander-Braid Transition Of The Lower Missouri River Valley, Michele Viola Kashouh
Earth & Environmental Sciences Theses - Archive
Historically, the Lower Missouri River is known for being a temperate river that constantly and quickly reworks its floodplain with a braided network of channels; however, the river only recently became braided. Ox-bow lakes and landscape features resembling highly sinuous meandering loops mark the floodplain of the lower Missouri River Valley as scars of what was once a fully meandering Missouri River. The unanswered question then is, when did the lower Missouri River system change from meandering to braided? To answer this question we compared a series of newly created allostratigraphic maps of the lower Missouri River valley floor to …
