DYNAMIC COMPLEXITY OF A THREE SPECIES COMPETITIVE FOOD CHAIN MODEL WITH INTER AND INTRA SPECIFIC COMPETITIONS

The present article deals with the inter specific competition and intra-specific competition among predator populations of a prey-dependent three component food chain model consisting of two competitive predator sharing one prey species as their food. The behaviour of the system near the biologically feasible equilibria is thoroughly analyzed. Boundedness and dissipativeness of the system are e...

Learning Competitive Equilibrium in Laboratory Exchange Economies

Crockett, Spear and Sunder [2005b] propose an algorithm whereby boundedly rational agents with standard neoclassical preferences learn competitive equilibrium in a repeated static exchange economy. In this paper a laboratory market is instituted to examine the hypothesis that people are at least as sophisticated as these agents. The adopted market institution strongly restricts the space of age...

A General Equilibrium Model of the Three - Sector Competitive Economy

The presence of externality, indivisibility, and uncertainty destroys the market's ability to coordinate production. Entrepreneurs rise to organize production by assuming a part of the allocative role traditionally reserved exclusively to the market. Assume that there are three classes of entrepreneurs: profit-oriented, nonprofit oriented and public entrepreneurs. These entrepreneurs cooperate ...

Competitive exclusion of heterologous Campylobacter spp. in chicks.

Chicken and human isolates of Campylobacter jejuni were used to provide oral challenge of day-old broiler chicks. The isolation ratio of the competing challenge strains was monitored and varied, depending upon the isolates used. A PCR-restriction fragment length polymorphism assay of the flagellin gene (flaA) was used to discriminate between the chick-colonizing isolates. Our observations indic...
