This paper discusses how optimal monetary policy is affected by differences in the combination of shocks an economy experiences and the rigidities it exhibits. Without both nominal rigidities and economic shocks, monetary policy would be irrelevant. Recognizing this, policymakers increasingly...

We examine the impact of wage stickiness when employment has an effort as well as hours dimension. Despite wages being predetermined, the labor market clears through the effort margin. We compare this model quantitatively to models with flexible and sticky wages, but no effort margin. Allowing...

Using the Panel Study of Income Dynamics, we find that true wage changes have many fewer nominal cuts and more nominal freezes than reported nominal wage changes. The data overwhelmingly rejects a model of flexible wage changes and provides some evidence against a model of perfect downward...

Sectoral contracts in many European countries set wage floors for different occupation groups. In addition, employers often pay a wage premium (or wage cushion) to individual workers. We use administrative data from Portugal, linked to collective bargaining agreements, to study the interactions...

I propose a financial channel of wage rigidity. In recessions, rather than propping up marginal (new hires') costs of labor, rigid average wages squeeze cash flows, forcing firms to cut hiring due to financial constraints. Indeed, empirical cash flows and profits would turn acyclical if wages...

We consider a New Keynesian model with downward nominal wage rigidity (DNWR) and show that government spending is much more effective in stimulating output in a low-inflation recession relative to a high-inflation recession. The government spending multiplier is large when DNWR binds, but the...

We adapt the wage contracting structure in Chari (1983) to a dynamic, balanced-growth setting with re-contracting à la Calvo (1983). The resulting wage-rigidity framework delivers a model very similar to that in Jaimovich and Rebelo (2009), with their habit parameter replaced by our probability...

This paper rehabilitates the old wage price spiral. It shows that, after an increase in aggregate demand, the process of adjustment of nominal prices and nominal wages results from attempts by workers to maintain or increase their real wage and by firms to maintain or increase their markups of...

This paper considers two sets of theories attempting to explain wage rigidities and unemployment: implicit contract theory and the efficiency wage theory. The basic thesis of the paper is that the former set of theories do not provide a convincing explanation of the kind of wage rigidity which...
