Though aesthetics is generally acknowledged as an important aspect of website design, extant information systems (IS) research on web user experience has rarely studied what affects website aesthetics and how aesthetics influences users’ perceptions of the website and the organization behind the website. In this paper, we synthesize prior literature from different academic domains and propose u...

We study Hotelling’s classic duopoly location model in continuous time with flow payoffs accumulated over time and the price dimension made explicit. In an experimental setting, subjects chose price and location in treatments varying only by the speed of adjustment. We find that the principle of minimum differentiation generally holds, with little distance between subjects’ location decisions. ...

The diffusion of a new product, whose price is expected to fall progressively, is modelled as a sequence of Wars of Attrition. The likely pattern of diffusion is found to be reasonably consistent with the empirically observed S-shape.

In this paper we study the opportunities of commercial exploitation of applications based on sensor networks. Such applications are quite famous nowadays in many different domains of everyday life (e.g., health monitoring, traffic monitoring). We introduce a new business model for sensor based services. Such business model involves entities like the mobile network operator and capitalizes on ex...

In the past fifteen years, an extraordinary development has occurred in economies throughout the world: inflation has fallen dramatically in many industrialised as well as emerging-market countries, to the point where many of them have reached what might arguably be called price stability. Why did this happen and how did policy-makers achieve this feat? This paper examines these questions by fi...

The realized size and value premia reflect earnings-induced price surprises that do not fit the rational pricing story. In addition, they seem to have little to do with systematic risks. This is because the majority of value or small firms with persistently high systematic risks are not rewarded with a premium. The premium happens, as a price adjustment, only to the subset of migrating firms wh...

The Maastricht Treaty contains the following statutory mandate: “The primary objective of the ESCB shall to be to maintain price stability.“ But why attach such importance to price stability and what does “price stability” mean? The latter question contains an historical component, the former is of a theoretical nature. I will therefore deal with the “what” and the “why” of my theme in the foll...

This paper summarizes the major findings from a nonresponse bias analysis of the Early Childhood Longitudinal Study, Kindergarten Class of 1998-99 (ECLS-K) first grade data. The analysis examines the potential for bias in estimates from the ECLS-K due to attrition (nonresponse) between the base year (rounds 1 and 2) and first grade (rounds 3 and 4). This work builds on a base year nonresponse b...

This paper studies infinite-horizon bargaining between a seller and multiple buyers when externalities are present. We extend the analysis in Jehiel & Moldovanu (1995a) by allowing for both pure and mixed equilibria. A characterization of the stationary subgame perfect equilibria in generic games is presented. Equilibria with delay exist only for strong positive externalities. Since each buyer ...
