This paper reviews recent approaches to modeling the labour market and assesses their implications for inflation dynamics through both their effect on marginal cost and on price-setting behavior. In a search and matching environment, we consider the following modeling setups: right-to-manage...

This paper proposes two models in which price stickiness arises endogenously even though firms are free to change their prices at zero physical cost. Firms are subject to idiosyncratic and aggregate shocks, and they also face a risk of making errors when they set their prices. In our first...

We study the cyclical dynamics of job creation and destruction when workers' effort is not perfectly observable. The no-shirking constraint may amplify fluctuations in hiring by making firms' surplus share procyclical, and may cause a burst of inefficient firing when a downturn begins. But...
