Recent research and policy discussions have noted that the potentially increased competition among firms since the 1990s may affect inflation and economic activity. This paper considers the implications of this structural change on short-run inflation dynamics, and for assessing shocks to...

This paper studies the effect of competitive pressures on inflation dynamics. To this end it derives and estimates a New Keynesian Phillips curve in a model with endogenous firm entry. The number of active firms is inversely related to their market power. By taking into account the number of...

We estimate the macroeconomic benefits and international spillovers of an increase in competition using a general-equilibrium simulation model with nominal rigidities and monopolistic competition in product and labor markets. We draw three conclusions after calibrating the model to the euro area...

Using a general-equilibrium simulation model featuring nominal rigidities and monopolistic competition in product and labor markets, this paper estimates the macroeconomic benefits and international spillovers of an increase in competition. After calibrating the model to the euro area vs. the...

This paper studies how competition affects firms' expectations in a new dynamic general equilibrium model with rational inattention and oligopolistic competition where firms acquire information about their competitors' beliefs. In the model, firms with fewer competitors are less attentive to...

We estimate the macroeconomic benefits and international spillovers of an increase in competition using a general-equilibrium simulation model with nominal rigidities and monopolistic competition in product and labor markets. We draw three conclusions after calibrating the model to the euro area...

This paper develops a model where large financial intermediaries subject to systemic runs internalize the effect of their leverage on aggregate risk, returns and asset prices. Near the steady-state, they restrict leverage to avoid the risk of a run which gives rise to an accelerator effect. For...

This paper examines the way in which structural changes in the level of steady-state competitiveness and the trend rate of inflation affect inflation responses to monetary policy shocks, in scenarios chosen to capture broadly the conditions of the UK economy in the early 1990s and more recently....
