An economic system, or economic order, [1] is a system of production, resource allocation and distribution of goods and services within a society. It includes the combination of the various institutions , agencies, entities, decision-making processes, and patterns of consumption that comprise the economic structure of a given community.
The overlapping generations (OLG) model is one of the dominating frameworks of analysis in the study of macroeconomic dynamics and economic growth.In contrast to the Ramsey–Cass–Koopmans neoclassical growth model in which individuals are infinitely-lived, in the OLG model individuals live a finite length of time, long enough to overlap with at least one period of another agent's life.
More generally, complexity economics models are often used to study how non-intuitive results at the macro-level of a system can emerge from simple interactions at the micro level. This avoids assumptions of the representative agent method, which attributes outcomes in collective systems as the simple sum of the rational actions of the individuals.
The earlier term for the discipline was "political economy", but since the late 19th century, it has commonly been called "economics". [22] The term is ultimately derived from Ancient Greek οἰκονομία (oikonomia) which is a term for the "way (nomos) to run a household (oikos)", or in other words the know-how of an οἰκονομικός (oikonomikos), or "household or homestead manager".
The Anglo-Saxon model (so called because it is practiced in Anglosphere countries such as the United Kingdom, the United States, Canada, New Zealand, Australia [1] and Ireland [2]) is a regulated market-based economic model that emerged in the 1970s based on the Chicago school of economics, spearheaded in the 1980s in the United States by the economics of then President Ronald Reagan (dubbed ...

Ethics, politics and culture play important roles in determining the performance of systems. Common cultures may prohibit or restrict individual's satisfaction, ultimately changing the rule of the economic game while on the other hand, competitive societies may abuse of the economic system and overstimulate self-seeking.
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.
