Ramsey model

from Wikipedia, the free encyclopedia

The Ramsey model is a neoclassical model of growth theory . It is based on fundamental work by Frank Plumpton Ramsey (1928). The most important extensions were made by David Cass (1965) and Tjalling Koopmans (1965), which is why this model category is also called the Ramsey – Cass – Koopmans model .

classification

The Ramsey model is now the starting point for modern dynamic macroeconomics.

Ramsey’s fundamental question was how much should a society save if its goal is to maximize the welfare of its members over an indefinite period of time. In contrast to the Solow model, the savings rate results endogenously from the utility maximization problem of an infinitely long household.

One result of the Ramsey model is the so-called Keynes-Ramsey rule , the growth rate of consumption as a result of intertemporal utility maximization.
