Reconciling the New Keynesian Model with Observed Persistence

Kenneth Leong. Reconciling the New Keynesian model with observed persistence

Despite sound theoretical foundations a drawback of the New Keynesian model is its inability to generate adequate persistence in the variables it seeks to explain. A common solution is to modify the model to include lagged variables. However, this is unsatisfactory as many such modifications depart from the microeconomic underpinnings of the original model. This paper presents results from simu...

The New Keynesian Model

Robust Control and Persistence in the New Keynesian Economy

Since Keynes no economist would deny that expectations under uncertain conditions matter for the conduct of monetary policy, but still opinions about their formation are diverse. We build a hybrid New Keynesian Framework to analyze the in‡uence of model uncertainty on optimal interest rates under di¤erent degrees of rational forward-looking behavior, using recently developed robust control tech...

A New Keynesian Model with Heterogeneous Expectations

This paper introduces heterogeneous expectations into a New Keynesian model. Our primary theoretical contribution is to provide an aggregation result for a model with nominal rigidities and heterogeneous bounded rationality. We incorporate bounded rationality at the individual agent level and determine restrictions on expectations operators sufficient to imply aggregate IS and AS relations of t...

A New Keynesian Model with Overtime Labor

This paper extends the standard New Keynesian model by incorporating labor adjustment costs and overtime work. I show that labor frictions help reconcile the frequent price changes found in the microdata with the degree of sluggishness in inflation adjustment to output changes at the macro level. The introduction of labor frictions affects the dynamic behavior of economic variables (particularl...
