RECENT RESEARCH:

DEEP DYNAMICS (with Glenn Mickelsson and Karolina Stadin)

Combining micro and macro data, we construct demand-side shocks, which we take to be exogenous for individual firms. We estimate a reduced-form model to describe how firms adjust their production, employment, capital stock, and inventories in response to such shocks . Then, we chose the structural parameters of a theoretical model so that the theoretical model can match the impulse-response functions from the estimated reduced-form model. Firms’ reactions to demand-side shocks are well explained by a model where firms have modest market power, face convex adjustment costs and where they can vary utilization flexibly. The stock-out motive helps to explain inventory dynamics.

The Matching Process: Search or Mismatch? (with Karolina Stadin) currently under revision

We examine the matching process using monthly panel data for local labour markets in Sweden. We find that an increase in the number of vacancies has a very weak effect on the number of unemployed workers being hired: unemployed workers appear to be unable to compete for many available jobs. Vacancies are filled quickly and there is no (or only weak) evidence that high unemployment makes it easier to fill vacancies; hiring appears to be determined by labour demand while frictions and labour supply play small roles. These results indicate persistent mismatch in the Swedish labour market.

Product Market Imperfections and Employment Dynamics (with Mikael Carlsson and Stefan Eriksson)

How important is imperfect competition in the product market for employment dynamics? To investigate this, we formulate a model of employment adjustment with search frictions, vacancy costs, hiring costs, and imperfect competition in the product market. From this model, we derive a structural equation for employment that we estimate on firm-level data. We find that product market demand shocks have significant and quantitatively large effects on employment. This supports a model with imperfect competition in the product market. We find no evidence that the level of unemployment in the local labour market has a direct effect on job creation in existing firms. In some specifications, we find evidence of congestion effects, i.e., that hiring is slowed down if there are many vacancies in the local labour market.
