In this study, we explore the relationships among group size, the extent of interactions with other groups, and group performance in a stochastic environment. We have developed a modeling framework which allows the connections among the individual members constituting a group and the connections...

Social foraging differs from individual foraging because it alters both resource availability and the forager's behavior. We examined responses of starlings to the presence of conspecifics by manipulating foraging-group density experimentally, while ensuring that each subject's foraging...

Group foraging allows for individuals to exploit the food discoveries of other group members. If searching for food and searching for exploitation opportunities within a group are mutually exclusive alternatives, the decision to use one or the other is modeled as a producer-scrounger game...

This study seeks to provide the Philippines Medical Care Commission with short-run and long-run alternatives aimed at improving the performance of Medicare in terms of efficiency and equity. This bridges the findings of two baseline studies: Administrative Issues of Medicare I and Economic...

A simulation model based on classical population dynamics is developed to estimate the benefit-cost ratio performance of different typologies of housing with the purpose of identifying potential reductions in the total costs and hence resources used to sustain housing. A typical New Zealand...

Many contractors prefer on-site fabrication of rebar while others find that off-site fabrication is more advantageous. The economics of on-site and off-site fabrication of rebar need to be compared on the basis of several factors that include the project environment, wages, labour...

This paper documents the first version of the Land Use in Rural New Zealand Model (LURNZv1). It describes the overall modelling approach, the database underlying the model, and the construction of each module within the model. The model is econometrically estimated from national time series data...

Eine formale Analyse der Firmen- und Branchenentwicklung muß nicht auf so stark vereinfachenden und damit unrealistischen Annahmen zurückgreifen, wie dies in neoklassischen Modellen geschieht. Evolutorische Simulationsmodelle bieten sich hier als eine Alternative an. Sie gestatten eine...
