dc.description.abstractBased on economic methodology we model an ecosystem with two species in predator-preyrelationship: mice feed on grain and grain feeds on a resource. With optimizing behaviour ofindividual organisms a short-run ecosystem equilibrium is defined and characterized thatdepends on the farmer's use of fertilizer and on the mice population which, in turn, is affectedby pesticides. In that way, a microfounded agricultural production function is derived.Linking a sequence of short-run ecosystem equilibria yields the growth function of the micepopulation which is thus derived rather than assumed. In each period the farmer harvests allgrain in excess of some given amount of seed. If she maximizes her present-value profits,optimal farming is shown to depend on the prices of pesticide and grain. It is either optimal touse no pesticide or a moderate amount of pesticide or to apply a chattering control. Pesteradication is never optimal. On the other hand, if the farmer takes into account steady statemice populations only, it may be optimal to eradicate mice or to use no or a moderate amountof pesticide depending on prices as well as on the shape of the grain production functionwhich is determined by micro parameters of grain reproduction.en
