This paper provides an outline of the historical development of Keynesian macroeconomics. It first argues that the business-cycle model of J.M. Keynes's General Theory featured analytical ingredients that were present in earlier writings and attained its theoretical precision only in...

Broadly defined, macroeconomic forecasting is alive and well. Nonstructural forecasting which is based largely on reduced-form correlations, has always been well and continues toquot; improve. Structural forecasting, which aligns itself with economic theory and hence rises andquot; falls with...

We investigate the role of macroprudential policies in mitigating liquidity traps driven by deleveraging, using a simple Keynesian model. When constrained agents engage in deleveraging, the interest rate needs to fall to induce unconstrained agents to pick up the decline in aggregate demand....

An otherwise conventional Keynesian macro model is modified to include inventories of final goods by (1) drawing a distinction between production and final sales, and (2) allowing for a negative effect of the level of inventories on production. Two models are presented: one in which the labor...

An aggregate demand - aggregate supply framework is used to analyze the effects of Japanese monetary policy, 1973:1-1990:8. It is found that money supply shocks contribute relatively little to output variability over the sample as a whole. Nor do these shocks seem to be particularly marked...

This paper discusses the reemergence of Keynesian economics during the past decade. It highlights the substantial differences between new Keynesian economics and the convictions of early Keynesians. In particular, it points out that new Keynesians have adopted many views that were once...

This paper studies a New-Keynesian model in which monetary policy may switch between regimes. We derive sufficient conditions for indeterminacy that are easy to implement and we show that the necessary and sufficient condition for determinacy, provided by Davig and Leeper, is necessary but not...

We study supply and demand shocks in a general disaggregated model with multiple sectors, multiple factors, input-output linkages, downward nominal wage rigidities, credit-constraints, and a zero lower bound. We use the model to understand how the Covid-19 crisis, an omnibus of supply and demand...

We demonstrate the importance of intertemporal marginal propensities to consume (iMPCs) in disciplining general equilibrium models with heterogeneous agents and nominal rigidities. In a benchmark case, the dynamic response of output to a change in the path of government spending or taxes is...

In the late 1960s the stable negatively sloped Phillips Curve (PC) was overturned by the Friedman-Phelps natural rate model. Their PC was vertical in the long run at the natural unemployment rate, and their short-run curve shifted up whenever unemployment was pushed below the natural rate. This...
