Bitcoin

A bitcoin's value derives solely from the belief that others will want to use it for trade, which implies that its purchasing power is likely to fluctuate over time to a degree that will limit its usefulness.

Bitcoin usefulness is limited mainly by other factors. Currencies can be useful for trade in large part because they are accepted for trade.

10 New Economic Experts join the IGM Panel


For the past two years, our expert panelists have been informing the public about the extent to which economists agree or disagree on important public policy issues. This week, we are delighted to announce that we are expanding the IGM Economic Experts Panel to add ten new distinguished economists. Like our other experts, these new panelists have impeccable qualifications to speak on public policy matters, and their names will be familiar to other economists and the media.

To give the public a broad sense of their views on policy issues, each new expert has responded to a selection of 16 statements that our panel had previously addressed. We chose these 16 statements, which cover a wide range of important policy areas, because the original panelists' responses to them were analyzed in a paper comparing the views of our economic experts with those of the American public. You can find that paper, by Paola Sapienza and Luigi Zingales, here. The paper, along with other analyses of the experts' views, was discussed during the American Economic Association annual meetings, and the video can be found here.

The new panelists' responses to these statements can be seen on their individual voting history pages. Our ten new economic experts are:

Abhijit Banerjee (MIT)
Markus K. Brunnermeier (Princeton)
Liran Einav (Stanford)
Amy Finkelstein (MIT)
Oliver Hart (Harvard)
Hilary Hoynes (Berkeley)
Steven N. Kaplan (Chicago)
Larry Samuelson (Yale)
Carl Shapiro (Berkeley)
Robert Shimer (Chicago)


Please note that, for the 16 previous topics on which these new panelists have voted, we left the charts showing the distribution of responses unchanged. Those charts reflect the responses that our original panelists gave at the time, and we have not altered them to reflect the views of the new experts.

We have also taken this opportunity to ask our original panelists whether they would vote differently on any of the statements we have asked about in the past. Several experts chose to highlight statements to which they would currently respond differently. In such cases, you will see this "revote" below the panelist's original vote. We think you will enjoy seeing examples of statements on which some experts have reconsidered.

As with the 16 previous statements voted on by new panelists, these "revote" responses are not reflected in the chart that we display showing the distribution of views for that topic: all the charts for previous questions reflect the distribution of views that the experts expressed when the statement was originally posed.

About the IGM Economic Experts Panel

This panel explores the extent to which economists agree or disagree on major public policy issues. To assess such beliefs we assembled this panel of expert economists. Statistics teaches that a sample of (say) 40 opinions will be adequate to reflect a broader population if the sample is representative of that population.

To that end, our panel was chosen to include distinguished experts with a keen interest in public policy from the major areas of economics, to be geographically diverse, and to include Democrats, Republicans and Independents as well as older and younger scholars. The panel members are all senior faculty at the most elite research universities in the United States. The panel includes Nobel Laureates, John Bates Clark Medalists, fellows of the Econometric society, past Presidents of both the American Economics Association and American Finance Association, past Democratic and Republican members of the President's Council of Economics, and past and current editors of the leading journals in the profession. This selection process has the advantage of not only providing a set of panelists whose names will be familiar to other economists and the media, but also delivers a group with impeccable qualifications to speak on public policy matters.

Finally, it is important to explain one aspect of our voting process. In some instances a panelist may neither agree nor disagree with a statement, and there can be two very different reasons for this. One case occurs when an economist is an expert on a topic and yet sees the evidence on the exact claim at hand as ambiguous. In such cases our panelists vote "uncertain". A second case relates to statements on topics so far removed from the economist's expertise that he or she feels unqualified to vote. In this case, our panelists vote "no opinion".

The Economic Experts Panel questions are emailed individually to the members of the panel, and each responds electronically at his or her convenience. Panelists may consult whatever resources they like before answering.

Members of the public are free to suggest questions (see link below), and the panelists suggest many themselves. Members of the IGM faculty are responsible for deciding the final version of each week’s question. We usually send a draft of the question to the panel in advance, and invite them to point out problems with the wording if they see any. In response, we typically receive a handful of suggested clarifications from individual experts. This process helps us to spot inconsistencies, and to reduce vagueness or problems of interpretation.

The panel data are copyrighted by the Initiative on Global Markets and are being analyzed for an article to appear in a leading peer-reviewed journal.
