Simon Wren-Lewis on whether "central bankers need to keep quiet about policy matters that are not within their remit":
Should central bankers stick to talking about monetary policy?: Few disagree that the recent remarks on corporate governance and investment made by Andy Haldane (Chief Economist at the Bank of England) are interesting, and that if they start a debate on short-termism that would be a good thing. As Will Hutton notes, Hillary Clinton has been saying similar things in the US. The problem Tony Yates has (and which Duncan Weldon, the interviewer, alluded to in his follow-up question) is that this is not obviously part of the monetary policy remit.
Haldane gave an answer to that, which Tony correctly points out is somewhat strained. ...
I have in the past said very similar things to Tony...
However I am beginning to have second thoughts about my own and Tony's views on this. First, it all seems a bit British in tone. Tony worked at the Bank, and I have been involved with both the Bank and Treasury on and off, so we are both steeped in a British culture of secrecy. I do not think either of us are suggesting that senior Bank officials should never give advice to politicians, so what are the virtues of keeping this private? In trying to analyse how policy was made in 2010, it is useful to have a pretty good idea of what advice the Bank's governor gave politicians because of what he said in public, rather than having to guess. ...
It is often said that central bankers need to keep quiet about policy matters that are not within their remit as part of an implicit quid pro quo with politicians, so that politicians will refrain from making public their views about monetary policy. Putting aside the fact that the ECB never got this memo, I wonder whether this is just a fiction so that politicians can inhibit central bankers from saying things politicians might find awkward (like fiscal austerity is making our life difficult). In a country like the UK with a well established independent central bank, it is not that clear what the central bank is getting out of this quid pro quo. And if it stops someone with the wide ranging vision of Haldane from raising issues just because they could be deemed political, you have to wonder whether this mutual public inhibition serves the social good.
The danger is that the Fed will become politicized as a result of taking sides on hotly debated political/policy questions. This is from a post in February of 2007:
As I've said before, I agree.
Fiscal policy has a clear connection to monetary policy through the government budget constraint, and there are also times -- e.g. recently -- when monetary policy needs the help of fiscal policy (if the Fed is forced to shoulder the entire burden, it can bring other risks). So I have no problem with the Fed chair raising fiscal policy issues (as Bernanke did, though not forcefully enough perhaps). I have a bit more trouble when the topic is inequality (e.g. Yellen's big speech on this -- and the subsequent reaction from the right). It's harder to see how that is connected to the Fed's policy mandate, and with Republicans already out to take away as much of the Fed's powers as they can, it was a bad time to tick them off.
Maybe this is too cautious. Perhaps Federal Reserve officials should feel free to address whatever topic they'd like. But the Fed's independence was instrumental during the Great Recession -- without it, monetary policy would have been as terrible as fiscal policy and things would have been much worse -- and I'd rather not take any risks.

This is from the NBER (Project Syndicate, are you listening?):
Content Aggregation by Platforms: The Case of the News Media, by Lesley Chiou and Catherine Tucker, NBER Working Paper No. 21404, July 2015: ... In recent years, the digitization of content has led to the prominence of platforms as aggregators of content in many economically important industries, including media and Internet-based industries (Evans and Schmalensee, 2012).
These new platforms consolidate content from multiple sources into one place, thereby lowering the transactions costs of obtaining content and introducing new information to consumers. ... For these reasons, platforms have attracted considerable legal and policy attention. ...
Our results indicate that ... the traffic effect is large, as aggregators may guide users to new content. We do not find evidence of a scanning effect...
Our empirical distinction between a scanning effect where the aggregator substitutes for original content and a traffic effect where the aggregator is complementary, is useful for analyzing the potential policy implications of such business models. The fact we find evidence of a "traffic effect" even with a relatively large amount of content on an aggregator, is perhaps evidence that the "fair use" exemptions often relied on by such sites are less potentially damaging to the original copyright holder than often thought.
On the comment that the benefits outweigh the harm "even with a relatively large amount of content on an aggregator," when I post an entire article, as I did yesterday with this Vox EU piece, a surprisingly high percentage of you still click through to the original.
With video, at least in most cases, there is code available to put the video on your site. You play it and it has ads, branding, etc. I've always thought (or maybe hoped) content providers should do the same thing. Provide an embed button that allows me to duplicate an article -- it would come with ads, links to other content on their site, etc. -- on my site. Reads of the article would go way up (not from just my site, I mean if they allowed everyone to do this), and it would increase the number of people who see ads associated with their content (so they could charge more).

Cecchetti & Schoenholtz:
Are we overestimating inflation (again?): Twenty years ago, a group of experts – the "Boskin Commission" – concluded that the U.S. consumer price index (CPI) systematically overstated inflation by 0.8 to 1.6 percentage points each year. Taking these findings to heart, the Bureau of Labor Statistics (BLS) got to work reducing this bias, so that by the mid-2000s, experts felt it had fallen by as much as half a percentage point.
We bring this up because there is a concern that as a consequence of the way in which we measure information technology (IT), health care, digital content and the like, the degree to which conventional indices overestimate inflation may have risen. ...
When indices like the consumer price index (CPI) or the personal consumption expenditure price index (PCE) persistently overstate inflation, there are important consequences. So long as the upward bias is constant, central bankers can (and do) modify their inflation targets. Yet, these price indexes also are used to adjust entitlement benefits without correcting for any persistent bias. And, they can have an important impact on public discourse. In particular, upward bias means that the median real wage may have risen substantially over past decades, in contrast to reported stagnation.
If the overstatement of inflation has increased during the past decade, this also has profound consequences. For one thing, the reported slowdown in annual productivity growth – from something like 2½% in the decade prior to the crisis to about 1% today – could be more apparent than real. For another, true inflation may be even further below the Federal Reserve's long-run objective of 2% on the PCE than current readings imply.
There is good reason to think that the price mismeasurement problem has gotten worse, but quantifying that deterioration is another thing. The impact on inflation may turn out to be small – perhaps an extra ¼% annually – leaving it well within the range of uncertainty that the Boskin Commission highlighted 20 years ago. ...
After presenting their analysis, they end with:
So, what's the bottom line? We have little doubt that inflation has been overstated for decades. That means that the rise of U.S. real output, real income, productivity, and living standards has been understated materially over the long run. In recent years, IT price mismeasurement probably has worsened this growth and productivity bias significantly. But the potential impact of IT mismeasurement on measures of consumer price inflation – which has been the source of much discussion – is small compared to what a worsening bias in health care prices would imply.
[There is a large controversy surrounding the Boskin report that I am ignoring.]
