Land, labor, indigenous knowledge and institutional resources of producers in the Central Highlands of Ethiopia are investigated. Frequency distribution and comparative statistical analysis of the two regions with respect to these and other parameters suggest that in a situation where all...

The aim of this paper is to demonstrate that dynamic paths in a model of discrete choice with social interactions, which have been developed by Brock and Durlauf (1999, 2001a, 2001b, 2006), converge some self-consistent equilibrium. To this aim, we propose an asynchronous model of...

In this study, we develop a theoretical model based on social network theory to understand how the collaboration (co-authorship) network of scholars correlates to the research performance of scholars. For this analysis, we use social network analysis (SNA) measures (i.e., normalized closeness...

This paper analyzes optimal retailer pricing in dense transshipment networks. Given the complexities associated with logistic profit functions (Hanson and Martin 1996; Hongmin and Woonghee 2011), a key insight of the paper is that prices become much easier to analyze as the network becomes dense....

We propose a model for the evolution of market share in presence of social influence. We study a simple market in which the individuals arrive sequentially and choose one of the available products. Their decision of which product to choose is a stochastic function of the inherent quality of the...

Exploration is a costly activity that helps a business improve their understanding of a potential mineral deposit. Yet, even with strong exploration results, the business faces uncertainty over the value of the mine. I model this situation as a game of chance. The game starts by giving an agent...

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.

Traditional groups meetings are an inefficient and ineffective method for making forecasts and decisions. We compare two structured alternatives to traditional meetings: the Delphi technique and prediction markets. Delphi is relatively simple and cheap to implement and has been adopted for...
