This chapter defines the terms methods and models. A method is a family or class of models. A model is a piece of theory, a theoretical construction, which is intended to be applied to a certain range of facts. Models may thus be classified according the facts to which they are intended to refer; so there are models of international trade, of labour relations, of the money market, and so on. But a class of models, when the grouping was of this character, would not at all conveniently be called a method. The definition of ‘economic dynamics’ must follow from the definition of ‘economic statics’: when we have defined one, we have defined the other. A static condition is one in which certain key variables (the quantities of commodities that are produced and consumed, and the prices at which they are exchanged) are unchanging. A dynamic condition is then, by inevitable opposition, one in which they are changing; and dynamic theory is the analysis of the processes by which they change.

Keywords: economic theory; economic dynamics; economic statics; methods; models
