The new classical perspective takes root in three diagnostic sources of fluctuations in growth: the productivity wedge, the capital wedge, and the labor wedge. Through the neoclassical perspective and business cycle accounting one can look at the diagnostics and find the main ‘culprits’ for fluctuations in the real economy.
The Ramsey–Cass–Koopmans model, or Ramsey growth model, is a neoclassical model of economic growth based primarily on the work of Frank P. Ramsey in 1928, [1] with significant extensions by David Cass and Tjalling Koopmans in 1965.
The Harrod–Domar model dominated growth theory until Robert Solow [c] and Trevor Swan [d] independently developed neoclassical growth models in 1956. [55] Solow and Swan produced a more empirically appealing model with "balanced growth" based on the substitution of labor and capital in production. [59]
RBC theory builds on the neoclassical growth model, under the assumption of flexible prices, to study how real shocks to the economy might cause business cycle fluctuations. [ 7 ] The "representative consumer" assumption can either be taken literally or reflect a Gorman aggregation of heterogenous consumers who are facing idiosyncratic income ...
However, the neoclassical theory also asks what exactly is causing the supply and demand behaviors of buyers and sellers, and how exactly the preferences and productive abilities of people determine the market prices. Therefore, the neoclassical theory of value is a theory of these forces: the preferences and productive abilities of humans.
The Harrod–Domar model was the precursor to the exogenous growth model. [4] Neoclassical economists claimed shortcomings in the Harrod–Domar model—in particular the instability of its solution [5] —and, by the late 1950s, started an academic dialogue that led to the development of the Solow–Swan model. [6] [7]
He is perhaps best known for his article “Optimum Growth in an Aggregative Model of Capital Accumulation”, [2] which was a part of his dissertation. In this paper he proves a necessary and sufficient condition for efficiency in the neoclassical growth model first introduced by Frank Ramsey. A major difference to the standard Ramsey growth ...
The overlapping generations (OLG) model is one of the dominating frameworks of analysis in the study of macroeconomic dynamics and economic growth.In contrast to the Ramsey–Cass–Koopmans neoclassical growth model in which individuals are infinitely-lived, in the OLG model individuals live a finite length of time, long enough to overlap with at least one period of another agent's life.
