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...)
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).

Do we do threads🧵on #EconSky? I recently gave a talk on competition policy and startup acquisitions. Here are the main points:
1/ Since ~2001, acquisitions have overtaken IPOs as the primary "exit" for VC-backed startups. This shift impacts how competition plays out.
