We characterize the dispersion of firm-level productivity and demand shocks over the business cycle using Swedish microdata including prices and analyse the consequences for firms and the aggregate economy. Demand dispersion increases by more than productivity dispersion in recessions....

This paper analyses the impact of financial frictions on markup adjustments at the firm level. We use a rich panel data set that matches information on banking relationships with firm-level data. By relying on insights from recent contributions in the literature, we obtain exogenous credit...

We assess how demand and supply shocks (identified via the Blanchard and Quah (1989) SVAR approach) in 14 OECD countries affect mark-ups. We find that individual responses of markups to demand shocks push down the markup for most countries (confirmed in the panel analysis). On the other hand, a...

This paper examines the implications of segmented assets markets for the real and nominal effects of monetary policy. I develop a model, in which varieties of consumption bundles are purchased sequentially. Newly injected money thus disseminates slowly through the economy via second-round...

We study business cycles with cyclical returns to scale. Contrary to tightly parameterized production functions (Cobb-Douglas and Constant Elasticity of Substitution), we empirically identify strong input complementarity that leads to procyclical returns to scale. We therefore propose a flexible...

This paper uses industry and firm data to look at price cost mark-ups and firm profit margins in U.K. manufacturing and services. In particular it examines how they behave over the business cycle. It has two main findings. First, the estimated average mark-ups and the profit margin results both...

Different methods have been used in the literature to measure and analyze price markup cyclicalbehavior. We use a medium-scale DSGE Model with positive trend inflation, in which neutral technology,the marginal efficiency of investment, and monetary policy shocks drive aggregate fluctuations and...

Firms’ market power, measured by markups, has risen substantially and unequally across sectors. To evaluate the implications of these trends for monetary non-neutrality, we develop a quantitative menu cost model that covers multiple sectors with heterogeneous degrees of market competition. Two...
