The New Keynesian Synthesis - CORE

New Keynesian economics was developed in response to the New Classical school and attempts to provide micro foundations for Keynesian economics. New Keynesians assume that agents have rational expectations but also that there exits many market failures, such as imperfect competition, which cause price and wage rigidities. In New Keynesian models, these rigidities, or stickiness, lead to failures in the market adjustment mechanism and prevent the economy from reaching full employment. This school of thought recommends the government use fiscal and monetary policy to stabilise the economy.

(More precisely,optimal rules usually react to changes in the , rather than changes in outputper se.) In some simple New Keynesian DSGE models, itturns out that stabilizing inflation suffices, because maintainingperfectly stable inflation also stabilizes output and employment tothe maximum degree desirable. Blanchard and Galí have called thisproperty the 'divine coincidence'.However, they also show that in models with more than one marketimperfection (for example, frictions in adjusting the employmentlevel, as well as sticky prices), there is no longer a 'divinecoincidence', and instead there is a tradeoff between stabilizinginflation and stabilizing employment.

Besides sticky prices, another market imperfection built intomost New Keynesian models is the assumption that firms are . Infact, without some monopoly power it would make no sense to assumesticky prices, because under , any firm witha price slightly higher than the others would be unable to sellanything, and any firm with a price slightly lower than the otherswould be obliged to sell much more than they can profitablyproduce. Therefore, New Keynesian models assume instead that firmsuse their to maintain their prices above , so that even if they failto set prices optimally they will remain profitable. Manymacroeconomic studies have estimated typical firms' degree ofmarket power, so this information can be used in parameterizing NewKeynesian models.
