neokeynesians

Neokeynesianism is a modern economic school of thought that builds upon the principles of Keynesian economics, emphasizing the role of aggregate demand in explaining economic fluctuations and the importance of government intervention in stabilizing the economy. Emerging in the late 20th century, neokeynesian economists sought to refine and expand upon John Maynard Keynes’ theories, incorporating insights from microeconomics, macroeconomic modeling, and empirical research.

A core tenet of neokeynesian theory is the recognition of market imperfections, such as sticky prices and wages, which prevent the economy from automatically achieving full employment. Unlike classical economists, who assume markets self-correct through flexible prices, neokeynesians argue that rigidities in labor and product markets can lead to prolonged periods of unemployment and underutilized resources. This perspective justifies active fiscal and monetary policy to counteract recessions and maintain steady economic growth.

Neokeynesian models often rely on dynamic stochastic general equilibrium (DSGE) frameworks, which combine Keynesian insights with modern macroeconomic techniques. These models help explain business cycles, inflation dynamics, and the effectiveness of policy tools like automatic stabilizers (e.g., unemployment benefits) and discretionary spending. Critics, however, argue that some DSGE models oversimplify real-world complexities, such as financial market behavior or structural inequalities.

Prominent neokeynesian economists include Paul Krugman, Olivier Blanchard, and Lawrence Summers, who have influenced policy debates on issues like fiscal stimulus, wage rigidity, and the Phillips curve. While neokeynesian policies have been widely adopted in advanced economies, debates persist over their long-term sustainability, particularly regarding public debt and inflation risks. The school remains influential in shaping macroeconomic policy, particularly during economic crises, where its emphasis on demand-side management continues to guide government responses.
