For the bitcoin/blockchain enthusiasts, this is from Cecchetti & Schoenholtz:
Virtual Frenzies: Bitcoin and the Block Chain: Bitcoin has prompted many people to expect a revolution in the means by which we make and settle everyday payments. Our view is that Bitcoin and other "virtual currency schemes" (VCS) lack critical features of money, so their use is likely to remain very limited.
In contrast, the technology used to record Bitcoin ownership and transactions – the block chain – has potentially broad applications in supporting payments in any currency. The block chain can be thought of as an ever-growing public ledger of transactions that is encrypted and distributed over a network of computers. Even as the Bitcoin frenzy subsides, the block chain has attracted attention from bank and nonbank intermediaries looking for ways to economize on payments costs. Only extensive experimentation will determine whether there are large benefits.
Again, however, we are somewhat skeptical. Today's wholesale payments systems are so efficient that it is hard to see how or why one would make the costly and time-consuming effort to replace them. And the apparently high costs of retail transfers at least partly reflect factors that the block chain technology is unlikely to address. ...
After much discussion of these and other points:
So, what's the bottom line? We share with Bitcoin advocates the desire to protect privacy (see, our post on paper money), but remain skeptical about the potential for any private currency – digital or otherwise – to do the job better than what we currently use. And the evidence so far is that government fiat monies – dollar, euro, yen, or whatever – are far more stable than Bitcoin. Not only that, but if there's to be profit from issuing a currency, then we believe that it is the public that should benefit.
As for the block chain, there's plenty of room for experimentation – with the potentially greatest benefits coming where the current payments system is the least developed. But it remains to be seen whether the public ledger can compete against the big clearinghouses that dominate wholesale payments and settlement, and whether it can ensure payments providers have the ability to reliably filter out illegitimate transactions.
Of course, even a big clearinghouse might find the block chain technology useful (see WSJ-gated story here). Wouldn't it be ironic if it did so, but wished to keep the innovation private?

Michael Bauer and Erin McCarthy of the SF Fed:
Can We Rely on Market-Based Inflation Forecasts?, Michael D. Bauer and Erin McCarthy, Economic Letter, FRBSF: The Federal Reserve's dual mandate requires monetary policy to aim for both maximum employment and price stability. Although employment has recovered since the recession, inflation has consistently remained below the Fed's 2% longer-run objective. Because expectations of future inflation play an important role in determining current inflation, decreases in measures of inflation expectations based on market prices have raised some concerns. For example, between June 2014 and January 2015, one-year inflation swap rates, which measure market-based expectations of inflation in the consumer price index (CPI) one year ahead, dropped over 2.5 percentage points. Large decreases were also observed in breakeven inflation rates, the difference between yields on nominal and inflation-indexed Treasury securities, known as TIPS.
Market-based measures of inflation expectations are calculated from the prices of financial securities. Their advantage is that they are readily available at high frequency and therefore are widely monitored. However, they reflect not only the public's inflation expectations but also other idiosyncratic factors that affect market prices, which are difficult to quantify. For example, they include a risk premium to compensate investors for inflation uncertainty and are affected by changes in liquidity, unusual demand flows, and, more broadly, "animal spirits" that change prices but are unrelated to expectations (see Bauer and Rudebusch 2015). Hence it is unclear how much useful information they provide, and how much one should pay attention to these rates when forecasting inflation.
If market-based inflation expectations provided accurate inflation forecasts, then one surely would want to pay close attention to their evolution. In this Economic Letter, we evaluate their performance in comparison with a variety of alternative forecasts for CPI inflation. ...
Conclusions We find that market-based measures of inflation are poor predictors of future inflation. In particular, they perform much worse than forecasts constructed from survey expectations of future inflation, which incorporate all the information used by professional forecasters. Interestingly, a simple constant inflation rate corresponding to the Federal Reserve's 2% inflation target consistently performs best. While our analysis is based on a short sample that displays a lot of volatility during the Great Recession, our results appear quite robust as they are consistent across two subsamples.
Our results add to the discussion about how much attention policymakers and professional forecasters should pay to market-based inflation forecasts. These measures mostly reflect current and past inflation movements, and do not contain a lot of useful forward-looking information. Idiosyncratic market forces and inflation risk premiums appear to be important drivers of market-based inflation expectations. Overall, it is important to keep this caveat in mind when interpreting market-based inflation expectations.
