Lucas (1973) [r] proposed a business cycle theory based on rational expectations, imperfect information, and market clearing. While building this model, Lucas attempted to incorporate the empirical fact that there had been a trade-off between inflation and output without ceding that money was non-neutral in the short-run.

It turned out that pure new classical models had low explanatory and predictive power. The models could not simultaneously explain both the duration and magnitude of actual cycles. Additionally, the model's key result that only unexpected changes in money can affect the business cycle and unemployment did not stand empirical tests.
The graphic model shows combinations of interest rates and output that ensure equilibrium in both the goods and money markets under the model's assumptions. [49] The goods market is modeled as giving equality between investment and public and private saving (IS), and the money market is modeled as giving equilibrium between the money supply and ...
The new neoclassical synthesis (NNS), which is occasionally referred as the New Consensus, is the fusion of the major, modern macroeconomic schools of thought – new classical macroeconomics/real business cycle theory and early New Keynesian economics – into a consensus view on the best way to explain short-run fluctuations in the economy.
Real business-cycle theory (RBC theory) is a class of new classical macroeconomics models in which business-cycle fluctuations are accounted for by real, in contrast to nominal, shocks. [1] RBC theory sees business cycle fluctuations as the efficient response to exogenous changes in the real economic environment.
Business cycles are a type of fluctuation found in the aggregate economic activity of nations that organize their work mainly in business enterprises: a cycle consists of expansions occurring at about the same time in many economic activities, followed by similarly general recessions, contractions, and revivals which merge into the expansion ...
Lucas' model was superseded as the standard model of New Classical Macroeconomics by the Real Business Cycle Theory, proposed in 1982 by Finn Kydland (1943–) and Edward C. Prescott (1940–), which seeks to explain observed fluctuations in output and employment in terms of real variables such as changes in technology and tastes. Assuming ...
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.
