You’ve heard about bitcoin and other cryptocurrencies, but how are they different from a digital dollar? On this Whaddya Wanna Know Wednesday, we’ll discuss the benefits and drawbacks of a digital dollar as the Federal Reserve ponders making its own digital currency. Plus, we’ll explain the economics behind robocalls and vaccine mandates. And we get an email from a listener and her cats who want to know what’s up with pet food shortages.

Here’s everything we talked about today: 

• “What exactly is a digital dollar, and how would it work?” from Popular Science 

• “China’s digital yuan is a warning to the world” from Wired

• “Tired of robocalls? The FCC is stillllll trying to stop them” from “Marketplace Tech”

• “THE ANNOYANCE ENGINE: Spam robocalls became profitable scams by exploiting the phone system, but you can stop them” from Business Insider 

• “Fact check: Workers fired for refusing a vaccine are unlikely to qualify for unemployment” from USA Today 

• “Half of unvaccinated workers say they’d rather quit than get a shot – but real-world data suggest few are following through” from The Conversation 

• The Pet Food Institute on the pet food supply challenges
