Nominal rigidities imply that monetary neutrality is broken, but can they also account for persistent effects of nominal shocks? One possible propagation mechanism may arise from the fact that nominal price and wage decisions are not coordinated in a decentralized economy, but made by numerous...

Does it matter for the propagation mechanism following nominal shocks whether nominal rigidities are specified as sticky wages instead of sticky prices? We analyze the question in a standard dynamic general equilibrium "new open macro-economy" model, which is solved analytically. By comparing...

This chapter reviews the role of temporary price and wage rigidities in explaining of the dynamic relationship between money, real output, and inflation. The key properties to be explained are that monetary shocks have persistent, but not permanent, effects on real output, and that the...

Much recent research has focused on the development and analysis of extensions of the New Keynesian framework that model labor market frictions and unemployment explicitly. This chapter describes some of the essential ingredients and properties of those models, and their implications for...

This paper shows that a model which combines sticky prices and sticky wages with investment in the cash-in-advance constraint generates business cycle dynamics consistent with empirical evidence. The model reproduces the responses of the key macroeconomic variables to technology and money supply...

Recently, Barsky et al. (2007) found that a sticky-price model does not generate sectoral co-movement and that the propagation mechanism is weak in response to monetary shocks if prices in the durable goods sector are significantly flexible, which raises a co-movement problem in sticky-price...

I introduce sticky wages in the model with credit constrained or “rule of thumb” consumers advanced by Galì, Valles and Lopez Salido (2005). I show that wage stickiness i) restores, in contrast with the results in Bilbiie (2005), the Taylor Principle as a necessary condition for equilibrium...

This paper shows that a model which combines sticky price and sticky wages with investment in the cash-in-advance constraint generates business cycle dynamics consistent with empirical evidence. The model reproduces the responses of the key macroeconomic variables to technology and money supply...

This paper analyses the response of labor input to technology shocks in an estimated two-stage production framework with both price and wage stickiness and stage-specific shocks to productivity. Our model features a vertical input-output structure with imperfect mobility of labors across stages....

Standard New Keynesian (NK) models feature an optimal inflation target well below two percent, limited welfare losses from business cycle fluctuations and long-term monetary neutrality. We develop a NK framework with labour market frictions, endogenous productivity and downward wage rigidity...
