Sponsored Search: How Platforms Exacerbate Product Market Concentration

How does online advertising affect consumer behaviour, product pricing and competition? To analyse this, I develop a theory of digital markets where an intermediary provides a platform for firms to advertise their product and where consumers need to engage in costly search if they want to learn about the product characteristics.

Companies Contribute Significantly to the Integration of Refugees in Germany

Following the 2015 refugee influx, recent studies have found that around one in four companies have hired refugees. A survey of 100 companies that hired refugees shows that hiring refugees can increase employee satisfaction, improve reputations, and positively affect corporate developments.

Testing the Superstar Firm Hypothesis

Firms with superior productivity, labeled superstar firms, are argued to be the link between rising concentration and the fall of the aggregate labor share in the US.
