In microeconomics the focus of analysis is often a single market, such as whether changes in supply or demand are to blame for price increases in the oil and automotive sectors. From introductory classes in "principles of economics" through doctoral studies, the macro/micro divide is institutionalized in the field of economics.
Microeconomics also deals with the effects of economic policies (such as changing taxation levels) on microeconomic behavior and thus on the aforementioned aspects of the economy. [6] Particularly in the wake of the Lucas critique , much of modern macroeconomic theories has been built upon microfoundations —i.e., based upon basic assumptions ...
The 'neoclassical microeconomics' in mention is the Marshallian partial-equilibrium approach, which emerged from the Walrasian general equilibrium theory. [5] However, the Walrasian general equilibrium theory presents another trend to the synthesis as it attempts to theorise the economy as a whole and is viewed as an alternative to macroeconomics.
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".

A macroeconomic model is an analytical tool designed to describe the operation of the problems of economy of a country or a region. These models are usually designed to examine the comparative statics and dynamics of aggregate quantities such as the total amount of goods and services produced, total income earned, the level of employment of productive resources, and the level of prices.
The differentiation between long-run and short-run economic models did not come into practice until 1890, with Alfred Marshall's publication of his work Principles of Economics. However, there is no hard and fast definition as to what is classified as "long" or "short" and mostly relies on the economic perspective being taken.
Major topics include measurement of economic performance, national income and price determination, fiscal and monetary policy, and international economics and growth. AP Macroeconomics is frequently taught in conjunction with (and, in some cases, in the same year as) AP Microeconomics as part of a comprehensive AP Economics curriculum, although ...
