This paper examines the effects of changes in uncertainty of household income on the macroeconomy. Households face substantial idiosyncratic income risk that is up to two orders of magnitude larger than total factor productivity uncertainty, very persistent and varies substantially over the...

In this paper I study the relation between real wage rigidity (RWR) and nominal price and wage rigidity. I show that in a standard DSGE model RWR is mainly affected by the interaction of the two nominal rigidities and not by other structural parameters. The degree of RWR is, however,...

We study the implications of increased price flexibility on aggregate output volatility in a dynamic stochastic general equilibrium (DSGE) model. First, using a simplified version of the model, we show analytically that the results depend on the shocks driving the economy and the systematic...

This paper shows that an analytical determinacy analysis of the baseline New Keynesian model with both staggered wages and prices developed by Erceg, Henderson and Levin (2000) is possible despite the high dimensional nature of this model. It is possible if the formulation of the model is...

In this paper, we ask whether a small structural model with sticky prices and wages, embedding various modeling devices designed to increase the degree of strategic complementarity between price-setters, can fit postwar US data. To answer this question, we resort to a two-step empirical...

This paper documents how the frequency of price changes differs across sectors in Korea and what implications such heterogeneity may have for monetary policy. We find that under heterogeneity: i) monetary policy has larger and more persistent real effects; ii) it is welfare improving to...

We develop a parsimonious New Keynesian macro-finance model with downward nominal rigidities to understand secular and cyclical movements in Treasury bond premia. Downward nominal rigidities create state-dependence in output and inflation dynamics: a higher level of inflation makes prices more...

We formulate an optimizing-agent model in which both labor and product markets exhibit monopolistic competition and staggered nominal contracts. The unconditional expectation of average household utility can be expressed in terms of the unconditional variances of the output gap, price inflation,...
