Swedish Premium Pension Funds: Attributes and Performance

This study investigates the relationship between fund attributes and performance. The focus is on funds available in the Swedish Premium Pension system (PPM-funds). The aim has been to investigate whether administration fees, manager tenure or past performance are of importance for pension savers when they pick their PPM-funds. The results indicate that high fees are a disadvantage to pension savers investing in bond funds but not to those investing in stock funds. Manager tenure has no relationship with performance. There is evidence of performance persistency in most of the investigated fund categories.

Evaluacion del efecto de anabolicos de crecimiento (Zeranol over, Overmax L.A. Premium y Zeranol implante) en novillos de engorde en un periodo de cien dias en la finca El Rastro, El Coral, Chontales

Para el estudio se utilizaron 68 novillos producto del cruce de la raza Pardo Suizo x Brahman con un peso inicial de 230 ± 33 kg, con el objetivo de evaluar el efecto de tres tratamientos anabólicos sobre la ganancia de peso total en pastoreo libre durante un periodo de 100 días, siendo los tratamientos los siguientes: T 1 (Zeranol implante: Zeranol Over®), T2 (Zeranol Over® formulación tixotrópico), T3. (Overmax® LA Premium: Zeranol + ivermectina 3.15%), comparado con el T4 Testigo o Control (Sin implante). A los animales pesados y organizados en tres grupos con características semejantes, se les aplicó los tratamientos y cada grupo estuvo conformado por 17 novillos; de igual manera, fueron desparasitados con Vermectina La Premium 3. 15 %, a razón de 1ml por cada 50 kg de peso vivo (kg p.v), antes de aplicar los agentes anabólicos. Se determinó el incremento en peso a partir del peso final e inicial, y se calculó la Ganancia Media Diaria (GMD) en cada uno de los tratamientos. Para el diseño de dos vías se utilizó el test de Fisher (Análisis de Varianza) y el Test de Friedman, y categorización estadística mediante la Mínima Diferencia Significativa (DMS, P=O.OS). El análisis estadístico determinó efecto altamente significativo (P=O.OOl) en la GMD, en donde la GMD fue de 739, 624, 590 y de 536 gramos para los tratamientos T3 (Overeas® LA Premium: Zeranol + ívermectina), TI (Zeranol implante: Zeranol Over®), T2 (Zeranol Over'l formulación tixotrópica) y el Control, respectivamente. El implante Overmax® LA Premium (Zeranol+ivermectina3.15%) superó en más de 27 % al tratamiento sin implante, siendo este el tratamiento de mayor rentabilidad, con 83.43 dólares en ganancia de peso por animal, y una relación Beneficio/Costo de 1.27 por cada unidad monetaria invertida.

Markov Switching Risk Premium and the term structure of interest rates. Empirical evidence from US post-war interest rates

This paper considers the basic present value model of interest rates under rational expectations with two additional features. First, following McCallum (1994), the model assumes a policy reaction function where changes in the short-term interest rate are determined by the long-short spread. Second, the short-term interest rate and the risk premium processes are characterized by a Markov regime-switching model. Using US post-war interest rate data, this paper finds evidence that a two-regime switching model fits the data better than the basic model. The estimation results also show the presence of two alternative states displaying quite different features.

Understanding luxury in the premium automotive industry

This paper summarises the findings of investigations to date in understanding what luxury and premiumness mean to the high-end automotive consumer. Existing writings on luxury and premiumness are considered. An exploratory study was carried out in two countries using 309 respondents and 18 prestige cars. A "stream of consciousness" approach was used to capture respondent's views on a selection of vehicles. The codified transcripts were used to identify key differences between the top and bottom rated vehicles, in terms of the nature and quantity of emotional responses elicited. This paper describes some of these key product differences that were self-reported to impact upon a luxury response. Finally, suggestions are made as to the next steps required for this research. © 2007 ACM.

Characterisation of friction and lubrication regimes in premium tubular connections

A friction test rig has been developed to carry out repeated sliding friction tests for premium tubular connections. The test rig enables accurate measurement of friction in various contact regimes which are relevant to the threaded connections between tubular components. Higher load tests can simulate the contact in metal-to-metal seals under very high contact pressures by using perpendicular pin-on-pin tests. The contact in the thread loading flank under intermediate pressures can be simulated by using larger radius coupon-on-coupon tests. The measured coefficient of friction is well correlated with a lubrication parameter combining lubricant film thickness and initial surface roughness. © 2012 Elsevier Ltd. All rights reserved.

Trading-up on unmet expectations? Evaluating consumers’ expectations in online premium grocery shopping logistics

Geography and retail store location are inherently bound together; this study links food retail changes to systemic logistics changes in an emerging market. Current logistic practices underplay demand-led models and online market evolution in large metropolises such as Istanbul, Rio de Janeiro, and Delhi. The later include raising income and education, access to a wide range of technologies, traffic and transport difficulties, lagging retail provision, changing family structure and roles, as well as changing food culture and taste. The study incorporates demand for premium products defined by Kapferer and Bastien, (2009b) as comprising a broad variety of higher quality and unique or distinctive products and brands including in grocery organic ranges, healthy options, allergy free selections, and international and gourmet/specialty products through an online grocery model (n=356) that integrates a novel view of home delivery (HD) in Istanbul. More importantly from a logistic perspective our model incorporates any products from any online vendors broadening the range beyond listed items found in any traditional online supermarkets. Data collected via phone survey and analysed via structural equation modelling (SEM) suggest that the offer of online premium products significantly affects consumers’ delivery logistics expectations. We discuss logistics operations and business management implications, identifying the emerging geography of logistic models which respond to consumers’ unmet expectations using multiple sourcing and consolidation points.
