'''New Keynesian Economics''' is an economic school of thought that combines the macroeconomic insights of Keynesian Economics with insights from neoclassical economics. It is based on the idea that market participants are forward-looking and that prices and wages are slow to adjust to changes in the economic environment. This means that monetary and fiscal policy can have an effect on economic activity. The New Keynesian approach emphasizes that policy makers should focus on the stability of economic growth and the sustainability of economic welfare. It also stresses the importance of policies that help to ensure that the economy runs at its full potential.
==Example of new keynesian economics==
* The Federal Reserve's monetary policy is an example of New Keynesian Economics in [[action]]. The Fed adjusts its short-term [[interest]] rate (the federal funds rate) to influence the level of economic activity. When the economy is weak and [[inflation]] is low, the Fed will lower the federal funds rate in an effort to stimulate economic activity. Conversely, when the economy is strong and inflation is high, the Fed will raise the federal funds rate to slow economic activity and help keep inflation in check.
* Another example of New Keynesian Economics in action is the use of fiscal policy. The [[government]] can use fiscal policy to increase economic activity by cutting taxes and increasing spending. Conversely, the government can use fiscal policy to slow economic activity by raising taxes and decreasing spending. By adjusting taxes and spending, the government can influence the level of economic activity.  
* Additionally, policymakers can use New Keynesian Economics to improve the functioning of the labour market. For example, the government can use policies such as minimum wages, job protection laws, and [[unemployment]] benefits to encourage workers to stay in their jobs and to discourage employers from laying off workers during recessions. These policies are intended to help ensure that the labour market functions efficiently and that workers have access to job opportunities that match their [[skills and abilities]].

New Keynesian Economics is an economic school of thought that combines the macroeconomic insights of Keynesian Economics with insights from neoclassical economics. It is based on the idea that market participants are forward-looking and that prices and wages are slow to adjust to changes in the economic environment. This means that monetary and fiscal policy can have an effect on economic activity. The New Keynesian approach emphasizes that policy makers should focus on the stability of economic growth and the sustainability of economic welfare. It also stresses the importance of policies that help to ensure that the economy runs at its full potential.

  • The Federal Reserve's monetary policy is an example of New Keynesian Economics in action. The Fed adjusts its short-term interest rate (the federal funds rate) to influence the level of economic activity. When the economy is weak and inflation is low, the Fed will lower the federal funds rate in an effort to stimulate economic activity. Conversely, when the economy is strong and inflation is high, the Fed will raise the federal funds rate to slow economic activity and help keep inflation in check.
