[2] [3] The Ramsey–Cass–Koopmans model differs from the Solow–Swan model in that the choice of consumption is explicitly microfounded at a point in time and so endogenizes the savings rate. As a result, unlike in the Solow–Swan model, the saving rate may not be constant along the transition to the long run steady state.
In macroeconomics, investment "consists of the additions to the nation's capital stock of buildings, equipment, software, and inventories during a year" [1] or, alternatively, investment spending — "spending on productive physical capital such as machinery and construction of buildings, and on changes to inventories — as part of total spending" on goods and services per year.
where Y represents national income or GDP, C is consumption, I is investment, G is government spending and X–M stands for net exports. This represents GDP because all the production in an economy (the left hand side of the equation) is used as consumption ( C ), investment ( I ), government spending ( G ), and goods that are exported in ...

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 gross national income (GNI), previously known as gross national product (GNP), is the total amount of factor incomes earned by the residents of a country. It is equal to gross domestic product (GDP), plus factor incomes received from non-resident by residents, minus factor income paid by residents to non-resident. [2]: 44
[2] In the Solow growth model, a steady state savings rate of 100% implies that all income is going to investment capital for future production, implying a steady state consumption level of zero. A savings rate of 0% implies that no new investment capital is being created, so that the capital stock depreciates without replacement.
The General Theory of Employment, Interest and Money is a book by English economist John Maynard Keynes published in February 1936. It caused a profound shift in economic thought, [1] giving macroeconomics a central place in economic theory and contributing much of its terminology [2] – the "Keynesian Revolution".
