Basic diagram of the circular flow of income. The functioning of the free-market economic system is represented with firms and households and interaction back and forth. [2] The circular flow of income or circular flow is a model of the economy in which the major exchanges are represented as flows of money, goods and services, etc. between ...
An economic model is a theoretical construct representing economic processes by a set of variables and a set of logical and/or quantitative relationships between them. The economic model is a simplified, often mathematical , framework designed to illustrate complex processes.
A Robinson Crusoe economy is a simple framework used to study some fundamental issues in economics. [1] It assumes an economy with one consumer, one producer and two goods. The title " Robinson Crusoe " is a reference to the 1719 novel of the same name authored by Daniel Defoe .
Phase space graph (or phase diagram) of the Ramsey model. The blue line represents the dynamic adjustment (or saddle) path of the economy in which all the constraints present in the model are satisfied. It is a stable path of the dynamic system. The red lines represent dynamic paths which are ruled out by the transversality condition.

Graphical representation of Keynes's economic model, based on his own diagram at page 180 of the General Theory. The first equation asserts that the reigning rate of interest r̂ is determined from the amount of money in circulation M̂ through the liquidity preference function and the assumption that L(r̂)=M̂.
Since the model cannot be solved explicitly, it is instructive to analyze the trajectory of the economy in terms of a phase diagram. The two lines defining the center of the cycle divide the positive orthant into four regions. The figure below indicates with arrows the movement of the economy in each region.
In a later book, Essays in the theory of Economic Growth, [2] [3] she tried to lower the degree of abstraction. Robinson presented her growth model in verbal terms. A mathematical formalization was later provided by Kenneth K. Kurihara. Assumptions: [4] There is a laissez-faire closed economy. The factors of production are capital and labour only.
