Q. Describe the classical model of macroeconomics?

'The classical model' was a term coined by Keynes in the 1930s to signify essentially all the ideas of economics as they apply to macro economy starting with Adam Smith in the 1700s all the way up to the writings of Arthur Pigou in the 1930s.

Now we will describe the major characteristics of what we now call the classical model and how macroeconomic variables are determined in this model. We will focus on the cycles and all the components comprised in the GDP (consumption, investment, imports and exports) are variables where trend has been removed.
