This paper presents a review of recent developments that have taken place in the area of dynamic optimal control models in advertising subsequent to the comprehensive survey of the literature by Sethi in 1977. The basic problem underlying these models is that of determining optimal advertising...

The two reports and two articles (as well as a Commentary) that follow are the finalists from the 2004 ISMS Practice Prize Competition, representing the best examples of rigor plus relevance that our profession produces.

In this paper our previous work on monopoly and oligopoly new product models is extended by the addition of pricing as well as advertising control variables. These models contain Bass's demand growth model, and the Vidale-Wolfe and Ozga advertising models, as well as the production learning...

Recent studies of innovation diffusion have investigated cross-country heterogeneity, but implicitly assumed within-country homogeneity. As such, these studies potentially overlook within-country variations in diffusion patterns, which may be even more important to marketing managers and...

We present a survey design that generalizes static conjoint experiments to elicit inter-temporal adoption decisions for durable goods. We show that consumers’ utility and discount functions in a dynamic discrete choice model are jointly identified using data generated by this specific design....

Natural gas is a finite resource that may be estimated directly, through geophysical methodologies, or indirectly, through historical production data. The rapid growth in consumption of this limited natural resource, strictly connected to the oil economy, may lead to its imminent depletion and a...

We show how pre-averaging can be applied to the problem of measuring the ex-post covariance of financial asset returns under microstructure noise and non-synchronous trading. A pre-averaged realised covariance is proposed, and we present an asymptotic theory for this new estimator, which can be...

In this work we analyse the evolution of organic agriculture in Europe from the point of view of Innovations Diffusion Theory in order to understand the characteristics of the process, and the factors that have determined its course in the past. From the corresponding diffusion models for data...
