Construct truncation due to suboptimal person and item selection : consequences and potential solutionsMurray, Aja Louise January 2016 (has links)
Construct truncation can be defined as the failure to capture variation along the entire continuum of a construct reliably. It can occur due to suboptimal person selection or due to suboptimal item selection. In this thesis, I used a series of simulation studies coupled with real data examples to characterise the consequences of construct truncation on the inferences made in empirical research. The analyses suggested that construct truncation has the potential to result in significant distortions of substantive conclusions. Based on these analyses I developed recommendations for anticipating the circumstances under which construct truncation is likely to be problematic, identifying it when it occurs, and mitigating its adverse effects on substantive conclusions drawn from affected data.

Price Discrimination on Complementary Goods: Evidence from the Men's Shaving Razor MarketYang, Zheng 01 January 2019 (has links)
This dissertation analyzes the men's razor market to examine whether a monopolist can implement price discrimination for the complementary goods. I estimate a demand system for razors using the random coefficient logit model with market level sales data from the Nielsen Store Scanner dataset and individual demographic data from the March CPS. The estimated parameters are used to construct price-cost markups. By comparing the markups of different products, I find evidence that Gillette uses a two-part tariff strategy. This conclusion can be generalized as that of a monopolist setting the prices of tie-in products consistent with a two-part tariff.

A Study of the Self-Selection Method of Reading in the Sixth-Grade of the Ephraim Elementary SchoolArnoldson, Elliot J. 01 May 1962 (has links)
As educators have searched continuously for the best method to teach reading, numerous techniques have been advanced. Some of these techniques are comprised of basic elements in reading which are proven and used with much success and security on the part of the teacher, Others are tried, used, made popular for a short time and then are cast aside as in adequate teaching methods.

Executive compensation and firm performanceTian, Shu, Banking & Finance, Australian School of Business, UNSW January 2005 (has links)
This study considers the determination of the ex ante pay-performance relationship. A single-period partial equilibrium model is used to show that the executive income can be expressed as a function of the firm's return expressed in dollar terms. The executive income is jointly determined by the opening firm size and current return, which function as a managerial talent proxy and self-selection mechanism respectively. Comparing to Jensen and Murphy (1990) wealth-based Pay-Performance Sensitivity (PPS), this research presents an income-based PPS. The alternative PPS not only overcomes a misleading misspecification in Jensen and Murphy (1990), but also corrects Rosen's (1992) argument for only including return in the pay performance relationship. This research finds empirically that both the opening firm size and stock return play a significant role in determining executive income. This study provides supplementary evidence to Murphy's (1986) Learning Model. However, shareholder income may not be an ideal performance measure in capturing the multi-period pay-performance relationship.

Μέγεθος επιχείρησης και μισθοί στην ΕλλάδαΝούλη, Αγγελική 01 November 2010 (has links)
Στην παρούσα εργασία διερευνήσαμε τον τρόπο με τον οποίο διαμορφώνεται το μισθολογικό πλεονέκτημα μεταξύ των εργαζομένων σε επιχειρήσεις διαφορετικού μεγέθους. Για τους σκοπούς της ανάλυσης χρησιμοποιήθηκαν διαστρωματικά στοιχεία από το ελληνικό τμήμα της European Community Household Panel (ECHP) για το έτος 2001 (κύμα 8) και εφαρμόστηκαν τυπικές συναρτήσεις αμοιβών τύπου Mincer. Σύμφωνα με τα αποτελέσματα επιβεβαιώνεται και στην περίπτωση της ελληνικής αγοράς εργασίας η ύπαρξη μισθολογικού πλεονεκτήματος προς όφελος των εργαζομένων σε επιχειρήσεις μεγάλου μεγέθους. Επιπρόσθετα, εξετάστηκε η υπόθεση της συστηματικής επιλογής από την πλευρά των εργαζομένων ως προς το μέγεθος της επιχείρησης (μη τυχαία κατανομή) και με βάση τα αποτελέσματα η υπόθεση αυτή δεν απορρίφθηκε. Στο πλαίσιο αυτό επανεκτιμήθηκαν οι απλές συναρτήσεις αμοιβών διορθώνοντας για την μη τυχαία κατανομή. Επίσης, εφαρμόστηκαν τεχνικές διαχωρισμού των μισθολογικών διαφορών (Oaxaca) μεταξύ εργαζομένων σε επιχειρήσεις διαφορετικού μεγέθους. Με βάση τα αποτελέσματα βρέθηκε, ότι η διόρθρωση για την επιλογή του μεγέθους της επιχείρησης συμβάλλει στην αύξηση της ικανότητας ερμηνείας της παρατηρούμενης μισθολογικής διαφοράς μεταξύ εργαζομένων σε μικρές και μεγάλες επιχειρήσεις. / --

How Do Dividend Announcements Affect Bondholder and Shareholder Wealth?Turkiela, Jason 17 October 2014 (has links)
Dividend payments to shareholders can create conflicts between debt and equity investors as these payments can expropriate wealth from bondholders to shareholders. However, dividend payments can also serve as a signal regarding firms' future earnings. Utilizing both improved bond event study techniques as well as a conditional event study model to control for self-selection and the presence of confounding earnings announcements, I find that, on net, dividend increases represent a transfer of wealth from debtholders to shareholders. Nevertheless, bondholders react more favorably to larger dividend changes consistent with the presence of a positive signaling effect. The conditional event study approach also provides the ability to test whether managerial hesitancy in cutting dividends may represent an additional source of expropriation. My results indicate that while bondholders are clearly harmed by these implicit dividend increases, evidence in support of shareholders' gains is mixed.

SPECIALTY POULTRY PRODUCTION: IMPACT OF GENOTYPE, FEED STRATEGIES, ALTERNATIVE FEEDSTUFFS, AND DIETARY ENZYMES ON THE GROWTH PERFORMANCE AND CARCASS CHARACTERISTICS OF HERITAGE BREED CHICKENSFisher, Tatijana 01 January 2016 (has links)
There is a growing market for specialty poultry production using alternative genotypes and management systems. However, producers interested in specialty poultry production face several challenges. One challenge is that little published data exists regarding the growth and production parameters for alternative genotypes like slow-growing meat strains and heritage breeds. To address this challenge, research at the University of Kentucky examined the effect of feed strategies, alternative feedstuffs, and dietary enzymes on the growth and performance of heritage breeds of chicken used for either egg- or meat-production. The first trial documented the growth and nutrient intake of pullets from three heritage breeds (Rhode Island Red, Barred Plymouth Rock, and Black Australorp) and three egg-laying strains (Red Star, Black Star, and ISA Brown) on a self-selection feeding program through nineteen weeks of age. The second trial documented the growth and nutrient intake of males from those same three heritage breeds, a slow-growing meat-type strain (Red Ranger), and males and females from a fast-growing meat-type strain (Cornish Cross). Birds used a self-selection feeding program and were grown to a common weight of 2300 grams. Carcass characteristics of these birds were evaluated in the third trial. The fourth trial evaluated the partial replacement of corn and soybean meal with alternative feedstuffs (field peas, buckwheat, and flax seed) and dietary enzymes on the performance of straight-run commercial broilers and two alternative breeds of chickens: males from a Black Sex-Link cross and straight-run Rhode Island Reds. The fifth trial examined the use of sorghum and field peas to completely replace corn and soybean meal in formulated diets for two heritage breeds (Rhode Island Red and Barred Plymouth Rock). Results of these trials showed that heritage breed pullets had similar growth parameters and nutrient intake as commercial egg-laying strains. Heritage breed cockerels grew significantly slower and exhibited poorer feed efficiency than meat-type birds, but seemed to tolerate low nutrient density diets better. Overall, the findings of these studies could help producers interested in raising slow-growing meat-type chickens and heritage breeds create accurate business plans and determine if they can profitably produce meat and/or eggs for niche markets.
