We show that a sticky price model featuring firms' heterogeneity in terms of productivity and strategic complementarities in price setting delivers a strictly positive optimal inflation in steady state, differently from standard New Keynesian models. Due to strategic complementarities, more...

We use a general equilibrium model to show that a decrease in workers’ bargaining power amplifies the relative contribution to the output gap of adjustments along the extensive margin of labour utilization. This mechanism reduces the cyclical movements of marginal cost (and inflation) relative...

This paper discusses, theoretically and empirically, the relationship between two indicators: the profit share in value added and markups. While many commentators simply interpret the profit share as a proxy for markup, we show that with a production function with two inputs (i.e. labour and...
