On the exact variance of an unbiased product type estimator and its comparison with the sample mean

We consider the usual product estimator adjusted for its bias, considered by Robson (1957). The exact variance of this estimator has been obtained through a direct method. Its superiority over the sample mean and the product estimator is demonstrated. The research of these authors has been partially supported by their respective NSERC grants A3661 and A3989.     

Green hotel servicescape: attributes and unique experiences

ABSTRACT

The relationship between green hotel service attributes and consumption experiences remains unclear in the extant research, especially in the context of emerging economies such as India. This work uses a multi-method approach that combines in-depth interviews, word association and two-stage empirical validation to propose a three-dimensional framework for measuring a hotel’s green servicescape, composed of atmospherics, motifs and human encounters. Individual effects of each green servicescape sub-dimension on those of green experiential values, namely utilitarian, emotional, social and altruistic values, are examined. The results reveal interesting findings, some counterintuitive, which are expected to create new insights for academicians and practitioners alike.     

Estimation of seemingly unrelated regression equations: A brief survey

This paper presents a brief survey of the developments in the estimation of seemingly unrelated regression equation models covering a period of one and a half decades, including some of the recent results by the authors.     

Role of monetary policy in a New Keynesian economy: a note from a laboratory experiment

This paper discusses an experimental study on the role of monetary policy within a New Keynesian macroeconomic framework. The novelty of this article is that each subject was asked to forecast both the inflation rate and output gap at the same time one period ahead, which is an improvement over the existing literature. We find that if both the expected inflation rate and expected output gap is incorporated in the monetary policy rule then inflation can be anchored and stabilized more efficiently.     

Harsh voices,sound branding: How voiced consonants in a brand's name can alter its perceived attributes

This paper examines the sound-symbolic link between voiced obstruents (speech sounds created by obstructing the airflow) present in a brand name and the perceived product/brand attributes. In three studies (two using self-reported measures and one using an implicit reaction time paradigm), we tested the effect of voiced (b, d, g, z, v) versus voiceless obstruents (p, t, k, s, f) across 25 hypothetical brand names, on the perceived product attributes of harshness (vs. softness). Brand names with voiced (vs. voiceless) obstruents are perceived as harsh (vs. soft/mild). Results are described across two different product categories (e.g., toilet cleaner and skin conditioner), and also within the same product category (e.g., strong vs. light beer and strong vs. mild toilet cleaner). Since sound symbolism is culturally agnostic, brands expanding into international and linguistically different markets can use these insights to create brand names that will have international appeal, and can match the product and/or brand attributes that brands wish to convey to consumers.
