New short paper alert! 📘
I look at how linear demand systems handle changes in the number of products (n) and variety effects—building on Choné & Linnemer (2020), Spence (1976), and Levitan & Shubik (1980).

Hey, #EconSky, I am excited to share a new working paper with my amazing co-author Shiva Shekhar (check out his previous work here: sites.google.com/site/shivash...)
The Limits of Media See-Saws: Ad-Funded Platform Mergers Can Harm Both Sides Shiva Shekhar Radostina Shopova March 19, 2025 We study the welfare effects of a merger between ad-funded platforms facing elastic consumer demand. We show that advertising fees as well as quality investment levels by the platforms fall post-merger. Interestingly, despite the lower advertising fees, advertisers may be worse off when their value of interacting with consumers is high enough. The intuition for this result is that the decrease in quality investments post-merger reduces overall consumer participation. Thus, studying innovation incentives is important in these ad-funded markets as the well-known surplus see-saw result may not hold making both sides of the markets worse while the merged entity emerges as the sole winner.

After a look at the terms, it seems as if it still might be fine, but I am a little skeptical:

I guess now I cannot opt out anymore and I have to pay so that Facebook does not use my information for targeting ads... Is this in line with GDPR?

This just happened. I guess I missed the announcement of it coming.
