An analytical framework for retailer price and advertising decisions for products with temperature-sensitive demand

The demand for weather-sensitive products, such as beverages, ice creams, or chocolate varies with changes in temperature. Yet, retailers lack a framework to adapt the marketing mix elements, such as price and advertising, in line with such changes. We provide a theoretical framework to fill this gap by developing an analytical model to derive the optimal marketing mix when product demand depends on temperature. The model prescribes how price and advertising for different demand characteristics should be set following a temperature change. Integrating the temperature element in the marketing mix offers an original profit-enhancing strategy.     

Price Dynamics and Consumer Learning

This paper studies the price dynamics induced by strategic firm behavior in the presence of consumer learning about the uncertain quality differential of the products offered by a duopoly. It is found that consumers learn slowly and that prices converge also slowly to full-information levels. A consequence is that the incentives affirms to manipulate consumers' beliefs are persistent. Although pricing tends to be aggressive at the early stages, and average prices eventually increase over time, price wars may occur at intermediate stages of the product life cycle.     

Sustainable supply chain management in tourism

Sustainable supply chain management (SSCM) encapsulates the trend to use purchasing policies and practices to facilitate sustainable development at the tourist destination. Most research has focused on environmental aspects of manufacturing, while other aspects of sustainability or the challenges for the service sector are largely ignored. Yet SSCM is particularly important for tour operators, as the product depends on the activities of suppliers, such as accommodation, transport and activities. Therefore, tour operators' contribution to sustainable tourism will be more effective through the definition and implementation of policies that acknowledge responsibility for the impacts of suppliers. Exploratory research of SSCM practices amongst tour operators generated a wide range of examples of good practice across the whole supply chain, and recommendations are made for more widespread engagement.

Exogeneity in structural equation models

The practical relevance of several concepts of exogeneity of treatments for the estimation of causal parameters based on observational data are discussed. We show that the traditional concepts, such as strong ignorability and weak and super-exogeneity, are too restrictive if interest lies in average effects (i.e. not on distributional effects of the treatment). We suggest a new definition of exogeneity, KL-exogeneity. It does not rely on distributional assumptions and is not based on counterfactual random variables. As a consequence it can be empirically tested using a proposed test that is simple to implement and is distribution-free.     

Strategizing industry structure: the case of open systems in a low‐tech industry

Open systems strategy enables a sponsor to diffuse its technology and promotes standardization in an industry. However, this strategy has been studied in high‐tech settings. We hypothesize that, in a non‐high‐tech industry, a sponsor giving access to its technical knowledge may impact industry structure. Based on a survey of the U.S. tabletop role‐playing game (RPG) industry, our results highlight that the introduction of an open system in a sector creates an entry induction phenomenon and that these new entrants adopt more readily the open system than incumbents. Moreover, the average size of the firms in the industry decreases due to vertical specialization. Copyright © 2006 John Wiley & Sons, Ltd.     

Investment in public infrastructure with spillovers and tax competition between contiguous regions

Two contiguous regions compete to attract a population of heterogeneous firms. They choose infrastructure levels in a first stage and compete in taxes in a second stage. We study the properties of Subgame Perfect Nash equilibria in this stage game depending on the extent to which the benefits of infrastructure spill over from one region to the other. First, we show that the presence of inter-regional spillovers allows jurisdictions to control for the intensity of tax competition and therefore affects the optimal levels of infrastructure selected at equilibrium. Second, by comparing the non-cooperative and cooperative outcomes, we show that the extent to which regions overinvest in infrastructures negatively depends on the intensity of the spillovers.     

Is agriculture the engine of growth?

We seek to address formally the question raised by Gardner (2003) in his Elmhirst lecture as to the direction of causality between agricultural value added per worker and Gross Domestic Product (GDP) per capita. Using the Granger causality test in the panel data analyzed by Gardner for 85 countries, we find overwhelming evidence that supports the conclusion that agricultural value added is the causal variable in developing countries, while the direction of causality in developed countries is unclear. We also examine further the use of the Granger causality test in integrated data and provide evidence that the performance of the test can be increased in small samples through the use of the bootstrap.     

Cross-sectional regression analysis of return and beta in Japan

This paper investigates the relationship between return and beta using the cross-sectional regression method. Regression of return on beta without differentiating positive and negative market excess returns produces a flat relationship between return and beta. Taking into account the difference between positive and negative market excess returns yields significant conditional relationships between return and beta. The conditional relationship between return and beta is found to be in general better fit when the market excess return is negative than positive in terms of the goodness of fit measures such as R² and the standard error of the equation.     

Evolution of an international joint venture: The case of a French‐Brazilian joint venture

Considering the situation of low performance of joint ventures, a certain number of studies have concluded that there is a close relationship between the initial conditions of creation of joint ventures and their success or failure. Nevertheless, other explanatory factors can be identified through dynamic analysis of the joint venture. For this purpose, on the basis of the case of the Franco‐Brazilian Algar‐Bull joint venture in the information technology sector, from its creation in 1983 to its dissolution in 1998, the aim of our research is to study the influence of external evolution processes ( partners' adaptive strategies and changes in environmental constraints) on the success or failure of a joint venture. © 2006 Wiley Periodicals, Inc.     

Choice in Interactive Environments

In the early 21st century, firms are thinking seriously and practically about an interactive marketing paradigm—one that integrates mass scale with individual responsiveness. The focus of this paper is on how this interactive environment is changing the customer decision-making process. With the increased amount of information available, the existence of sophisticated decision aids such as intelligent agents, and more latitude in how to interact beyond the basic desktop and laptop computers (e.g., personal digital assistants, cellular phones, tablet computers), customers have more choices than ever about how, when, and how much to interact with companies and each other. In this paper, we attempt to cover a few of the major areas of research on how customers make decisions in these environments.
