The heterogeneity of inflation expectations, especially the residents’ inflation expectations, has a great influence on controlling the actual inflation rate and the effective implementation of my country’s monetary policy. In the process of monetary policy formulation, the monetary authorities need to pay more attention to the heterogeneous expectations among microeconomic individuals. This paper introduces the genetic algorithm, a new artificial intelligence method, to analyze the demand for the heterogeneity of inflation expectations and explains the basic steps to use it and how to apply it to explain problems in economics. Moreover, this paper uses a genetic algorithm-based generation overlap model to simulate the dynamic evolution of inflation heterogeneity among residents and the equilibrium selection process of price levels in a wide search space. The results of the simulation experiment show that it is of practical significance to use genetic algorithms to simulate the dynamic process of the heterogeneity of residents’ inflation expectations.

Abstract Starting out from classical metaphor theory, I consider two models, the Overlap model and the Tension model — the difference between which may not have been spelled out in that tradition. Although the latter has an Aristotelian pedigree, it may be less generally valid than the Overlap model, at least if the requirement for tension is placed very high. The metaphors distinguished by Lakoff and Johnson, like the catachresis of classical rhetoric, fulfils the Overlap model, but in a petrified form, as is shown by the fact that both may, in the same way, be awakened from their slumber by some modification or addition to the sentence. What Lakoff and Johnson, later on, call primary metaphors, however, does not really correspond to any of these models. They are quite literally extensions of human embodiments. Thus, they are actually diagrams, in the sense in which Peirce opposes them to metaphors. We go on to discuss similarities and differences between verbal and pictorial metaphors, arguing that some metaphorical configurations are more apt to work in pictures and others in language, although there are also some configurations which are common to both.
