Cross-impact analysis: Extended KSIM

The authors present an extension of Kane's cross-impact simulation model (ksim) that allows the inclusion of events and trends, and discuss the basic issues of forecasting and compatibility of forecasts.     

Order of entry,trial diffusion,and elasticity dynamics: An empirical case

This paper considers the diffusion process of new brands in order to estimate marketing mix elasticities and order-of-entry effects. Using an empirical case, we test hypotheses regarding the role of order of entry on brand trial processes within a new category. Consistent with research hypotheses, the results demonstrate that the diffusion rate of a brand's trials and its pricing and advertising elasticities vary systematically as a function of competitive entry. Competitive influences (which are negative) increase as order of entry is delayed. Short-term price elasticities are found to be an inverted U relationship with the order of entry, whereby early followers have the highest elasticities, as compared to the pioneer and to later followers. Advertising elasticities decline as the number of competitors increases.     

Academic foundations for hospitality and tourism research: A reexamination of citations

A 1999 study looking at the research relationships within and between the disciplines of hospitality and tourism is revisited. When compared to the 1999 study, the current study reveals that there is more within-discipline citing, suggesting that both the hospitality and tourism academic areas are maturing, and not relying as heavily on other disciplines. Further analysis of the citations outside hospitality is done to elicit a more in-depth picture of where hospitality and tourism citations are coming from. Implications are discussed.     

Minimal belief change, Pareto-optimality and logical consequence

Summary. A rational agent changes her beliefs in response to new information; a widely held idea is that such belief changes should be minimal. This paper is an overview of the theory of minimal belief revision. I employ a decision-theoretic framework to compare various principles for minimal belief revision. The main topics covered include the AGM postulates for belief revision, belief contraction, Grove's representation theorem, axioms for conditionals, and the connections between minimal belief change and questions in formal logic. I characterize under what conditions belief revision functions are consistent with the Levi Identity, and under what conditions belief contraction functions are consistent with the Harper Identity.

Takeover bids, unconditional offer price and investor protection

In this paper, we develop a contingent claim analysis on shareholders' right to sell unconditionally their shares at the acquisition bid price during a takeover bid procedure. Compared with a situation without any guarantee, this regulation brings about wealth transfer towards outside shareholders. Why, in an apparently irrational way, do outside shareholders, who may benefit from a price guarantee, not systematically sell their shares? That question emphasizes the outside shareholders' behavior. Using a real option valuation model to evaluate the price guarantee opportunity, we show that an equal treatment rule between controlling and outside shareholders may lead outside shareholders to sell their shares.     

The role of coworker support in the relationship between moral efficacy and voice behavior: The case of hospitality students in Ecuador

ABSTRACT

This article explores the relationships among employee moral efficacy, coworker emotional support, coworker instrumental support, and employee voice behavior regarding abusive supervision in the hospitality industry in Ecuador: a high power distance culture. The results indicate that employees’ moral efficacy predicted their voice behavior with regards to abusive supervision and that coworker emotional support strengthened this relation. However, an interaction effect between moral efficacy and coworker instrumental support on voice behavior was not found. This study provides a theoretical extension of the voice literature by introducing the roles of moral efficacy and coworker support, and has practical implications for the hospitality workplace.     

Do Investments in Specialized Knowledge Lead to Composite Good Industries?

We try to understand why firms producing goods by means of complementary components do not merge, especially in industries in which investments in component-based knowledge matters. As Audretsch, we state that these activities are developed by “individuals” who do their best to appropriate the return from their knowledge and whose effort is non-contractible. The organization of the industry into firms is identified to a partition of the set of individuals. In this context, we prove that an organization in which each individual hold his own firms is both stable with respect to unilateral deviation and optimal in the line of the property right approach. If the returns are high enough, this structure is even the only one which shares both properties.
