The present study constructs a decision support system to determine the best seeding rate out of a group of seeding rates applied in the field. The DSS has been built receives the field data as inputs, and then apply split plot algorithms of (Gomez & Gomez, 1984) to find the results. These...

The present study reviews the determination of the crop yield issues. Data analysis and utilization in the determination is essential for better production and economic performance. We follow the method of Williamson (1988) in discussing those issue and briefly compare them to application in Sudan.

In this paper we generalize the heterogeneous risk adverse agents model of diffusion of new products in a multi-firm, heterogeneous and interacting agents environment. We use a model of choice under uncertainty based on Bayesian theory. We discuss the possibility of product failures, the set of...

This paper analyzes the impact of risk and ambiguity aversion - Knightian uncertainty - on the choice of optimal quality and timing of market entry. Irreversibility of the investment in product development is introduced in a continuous-time stochastic model applying the real option literature....

The book deals with theoretical concepts and ways of practical implementation of information sytems in companies. A successful information system project has to be based on the information strategy of the company. Taking the business strategy into consideration the information system value for...

In their seminal paper, Grossman and Shapiro (1984) assume that it is not profitable for a firm to deviate to the supercompetitive price of Salop (1979). In this paper, it is shown that this assumption is violated if, roughly, each firm reaches less than half of all consumers unless it is a...

This paper examines one of the most important marketing strategies by software producers on the Internet. That is whether to offer free samples and if so, whether to list the samples on shareware repositories. I show that firms with higher value products have a greater incentive to offer free...

We consider a market in which firms can partially observe each consumer's search behavior in the market. In our main model, a firm knows whether a consumer is visiting it for the first time or whether she is returning after a previous visit. Firms have an incentive to offer a lower price on a...

In this paper, we analyze the careers from a sample of more than 1,000 top French chefs over more than twenty years and link it to the success or reputation of the restaurants where they have worked. This allows us to test what are the determinants of success but also to investigate the dynamics...
