Okay, so perhaps we don't like to repost to some of the bigger, traditional purveyors of economics, but here is a podcast on alternative local currency coming at you from Bloomberg...
The episode focuses on BerkShares, which is currency started in the Berkshires, MA. If you're familiar with E.F. Schumacher (Small is Beautiful) you may also know that his thinking inspired some very cool projects that continue to this day. One such initiative is the local BerkShare, one of the longest running and successful alternative currencies in the US.
So, back to Bloomberg - here is one of the largest US media publications ,that focuses on the economy (re: free market), taking the time to look at local currency. Hey, that's pretty good news and it's also a very informative and interesting podcast!
Give it a listen here.
