Based on economic methodology we model an ecosystem with two species in predator–prey relationship: mice feed on grain and grain feeds on a resource. With optimizing behavior of individual organisms a short-run ecosystem equilibrium is defined and characterized that depends on the farmer's use of fertilizer and pesticide and on the mice population which, in turn, is affected by 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 mice population which is thus derived rather than assumed. In each period the farmer harvests all grain in excess of some given amount of seed. If she maximizes her present-value profits, optimal farming is characterized by either using no pesticide or a moderate amount of pesticide or by applying a chattering control. Pest eradication is never optimal. On the other hand, if the farmer takes into account steady-state mice populations only, it may be optimal to eradicate mice or to use no or a moderate amount of pesticide depending on prices as well as on the shape of the grain production function which is determined by microparameters of grain reproduction. 相似文献

This paper is based on the samples of listed manufacturing companies of China, taking the financial performance as criterion, and then does research on the firm performance with different internal auditing modes, using Cross-sectional data to analyze the distribution of internal auditing modes and the characteristics of the firm performance. The conclusion is that setting up internal auditing is good for the development of companies, but the function of internal auditing has not been widelv fulfilled. 相似文献

Abstract In this paper we propose distribution-free treatments versus control tests for the one- and two-way classifications. The null distribution properties are shown to be equivalent to those of well-known statistics for which critical values have been extensively tabled. Asymptotic relative efficiencies with respect to corresponding normal theory competitors are derived and optimal designs for the allocation of experimental units to the treatments and control are obtained. 相似文献

This article first examines how bad housing conditions are in Japan based on international comparisons. The next question is whether the extremely high land prices in Japan can be explained by economic logic. We then turn to more specific housing policy questions that are peculiar to or important in Japan, such as the tax advantages of owning land that have caused under-utilization of land and the reasons why the average size of Japanese rental housing is so small. 相似文献
