I'm not an economist and it's maybe not directly related to your question but what do you think of the interest rates offered on BitAssets in BitShares?
Currently they're listed on the assets page and only BitUSD really has any CAP.
But a BitUSD is created when a long meets a short at 1-1 or higher. The shorts provide 200% collateral and compete on interest they are willing to pay longs. The result is a fully backed BitAsset that pays interest. The short gets the benefit of a leveraged position in BitShares.
I'm not sure what the average interest rates will be but imagine in the 3.5%+ range which is more than bank accounts. It's also quite amazing that you can earn interest on holdings like BitGold & BitSilver and BitBTC. (BitBTC holds the value of BTC but pays interest.)
They're not even on version 1.0, but with the main marketing push starting at the beginning of next month will be interesting to see if that's what the market is looking for. (I think the main thing the market is looking for is the decentralised advantages of Bitcoin without the volatility, so many use cases for things like BitUSD whereas there are very little for unstable crypto-currencies http://whatisbitusd.com/
