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. First, I show that when prices are observable...

We provide a description of ownership patterns in the top 25 European banks for the period 2003–2015, where we especially focus on the global financial crisis. Investment managers, such as Blackrock, are dominant in terms of number of blockholdings in different banks, maintaining fairly stable “common ownership” networks throughout our sample. However, the financial crisis led to capital injections ...
