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.
Notably this is the case in Olivier Blanchard's widely-used [13] intermediate-level textbook "Macroeconomics" since its 7th edition in 2017. [ 14 ] In this case, the LM curve becomes horizontal at the interest rate level chosen by the central bank, allowing a simpler kind of dynamics.

[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".
Ray Fair maintains a macroeconomic model, data, software and forecasts on his home page and that are also available for free downloading for use on a personal computer. The Fair Model macroeconomic model forecasts for the United States and 38 other countries. His model predicted a Trump victory in 2016. [2] Fair lives in New Haven, Connecticut.
Another example of a model in ecological economics is the doughnut model from economist Kate Raworth. This macroeconomic model includes planetary boundaries, like climate change into its model. These macroeconomic models from ecological economics, although more popular, are not fully accepted by mainstream economic thinking.
