Estimation results in linear regression models are sometimes in contrast with what was expected on the basis of a certain set of hypotheses or theory, in the sense that one or more parameters have the "wrong sign". One could be inclined to think that this is due to collinearity across...

It's time for a fresh look, a new perspective, on investment performance evaluation, because performance evaluation is conducted much the same way today as it was 30 years ago. While peer groups and indexes have painted fuzzy evaluative pictures, a modern-day application of classical statistics...

Nonmetric unfolding is a powerful (nonparametric) analytical tool generating a preference-based joint display of subjects (e.g., customers) and objects (e.g., brands or products). Systematic patterns in customers' preferences can be directly inferred from this display, and may provide valuable...

We examine the situation where hourly data are available to design advertising-response models, whereas managerial decision making can concern hourly, daily or weekly intervals. The key question is how models for hourly data compare to models based on weekly data with respect to forecasting...

We develop a bivariate spectral Granger-causality test that can be applied at eachindividual frequency of the spectrum. The spectral approach to Granger causality hasthe distinct advantage that it allows to disentangle (potentially) di®erent Granger-causality relationships over di®erent time...

Celebrity endorsement is omnipresent. However, despite its prevalence, it is unclear why celebrities are more persuasive than (equally attractive) non-famous endorsers. The present study investigates which processes underlie the effect of fame on product memory and purchase intention by the use...

Interactive decision aids (IDAs) typically use concrete product feature-based approaches to interact with consumers. Recently however, interaction designs that focus on communicating abstract consumer needs have been suggested as a promising alternative. This article investigates how temporal...

Research on the launch of new products in the international realm is scarce. The present paper is the first to document how launch window (difference in months between the first worldwide launch and the subsequent launch in a specific country) and launch price are interrelated and how regulation...

This paper shows how travellers that are faced with a series of risky choices become behaviourally inert due to a combination of risk aversion and learning. Our theoretical analyses complement other studies that conceive inertia as resulting from the wish to save cognitive resources. We first...

It has been twenty-five years since the publication of a comprehensive review of the full spectrum of sales-performance drivers. This study takes stock of the contemporary field and synthesizes empirical evidence from the period 1982–2008. The authors revise the classification scheme for sales...
