I am interested in macroeconomics, in particular in business cycles, in the role of information, expectations and learning, and in the role of heterogeneity in determining aggregate outcomes. Such models often pose specific computational challenges and require the development of new tools.

  • Firm-level Entry and Exit over the Danish Business Cycle (older Danmarks Nationalbank WP version)
    (with Svend Greniman Andersen)
    We use micro level registry data to study firm dynamics in Denmark. Similar to findings for the US, young firms are more likely to exit and to grow faster over time but Danish firms also take longer to reach maturity. We do not observe any signs of a slowdown in the entry rate or long-run scarring effects on firms entering in recessions. However, fluctuations in the entry rate have persistent effects on the long-run aggregate volume of value added.
    
    
  • WORKER FLOWS AND REALLOCATION IN COVID-19 EXPOSED SECTORS IN THE DANISH ECONOMY (June 2020)
    Past worker flows show that among the sectors hit hard by the COVID-19 epidemic, workers in "Transportation" accumulate relatively more human capital. In the event of large worker reallocation, this sector's productivity would be hit harder and need longer to recover due to the loss of firm and sector-specific knowledge and skills of the departing workers.
    
    
  • THE IMPACT OF DIGITALISATION ON DANISH COMPANIES AND WORKERS (February 2022)
    (with Saman Darougheh)
    This memo explores the impact of digitalisation on Danish workers and companies. For this, we first build two complementary measures of digitalisation that leverage Danish administrative data. We then document a positive association between the level of digitalisation and sales of large companies. In the final part, we study the workers in the IT sector - the producers of the digital tools. We find that the workforce in the IT sector is more specialised than the rest of the Danish workforce, and that this specialisation has increased during the past decade.
    
    
  • NEW: Pressure on the labour market during the pandemic (March 2022)
    (with Mikel Bess, Simon Hvid Juul and Erik Grenestan)
    The Danish labour market has tightened substantially during the recovery of the Danish economy. Pandemic-related labour demand can account for some of the employment growth. The majority of the movements on the labour market have occurred among marginal jobs, and cross-sectoral movements have been slightly higher than usual.
