The generation of economists that followed Keynes, the neo-Keynesians, created the "neoclassical synthesis" by combining Keynes's macroeconomics with neoclassical microeconomics. [38] Neo-Keynesians dealt with two microeconomic issues: first, providing foundations for aspects of Keynesian theory such as consumption and investment, and, second ...
The 'neoclassical microeconomics' in mention is the Marshallian partial-equilibrium approach, which emerged from the Walrasian general equilibrium theory.

[2] Within the macroeconomic mainstream in the United States, distinctions can be made between saltwater economists [a] and the more laissez-faire ideas of freshwater economists.
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.
