Einführung in die Mathematische Epidemiologie

Schistosomiasis (bilharzia) is a severe tropical disease. It is endemic in most regions where it occurs, that is in parts of Asia, Africa and South America. Estimates of how many people are infected vary from 200 to 400 million (1997). It was described by the ancient Egyptians 3,000 years ago (they mentioned blood in the urine as a symptom) and Napoleon’s troops suffered terribly from this dise...

We present a formal model of symmetric n-firm Cournot oligopoly with a heterogeneous population of profit optimizers and imitators. Imitators mimic the output decision of the most successful firms of the previous round a là Vega-Redondo (1997). Optimizers play myopic best response to the opponents’ previous output. The dynamics of the decision rules induce a Markov chain. As expression of bound...
