Replication in Economics

Posted: 10 May 2014 08:37 AM PDT

Thomas Kneib sent me the details of this project in early April after a discussion about it with one of his Ph.D. students (Jan Höffler) at the INET conference, and I've been meaning to post something on it but have been negligent. So I'm glad that Dave Giles picked up the slack:

Replication in Economics: I was pleased to receive an email today, alerting me to the "Replication in Economics" wiki at the University of Göttingen:

"My name is Jan H. Höffler, I have been working on a replication project funded by the Institute for New Economic Thinking during the last two years and found your blog that I find very interesting. I like very much that you link to data and code related to what you write about. I thought you might be interested in the following:

We developed a wiki website that serves as a database of empirical studies, the availability of replication material for them and of replication studies: http://replication.uni-goettingen.de

It can help for research as well as for teaching replication to students. We taught seminars at several faculties internationally - also in Canada, at UofT - for which the information of this database was used. In the starting phase the focus was on some leading journals in economics, and we now cover more than 1800 empirical studies and 142 replications. Replication results can be published as replication working papers of the University of Göttingen's Center for Statistics.

Teaching and providing access to information will raise awareness for the need for replications, provide a basis for research about the reasons why replications so often fail and how this can be changed, and educate future generations of economists about how to make research replicable.

I would be very grateful if you could take a look at our website, give us feedback, register and vote which studies should be replicated – votes are anonymous. If you could also help us to spread the message about this project, this would be most appreciated."

I'm more than happy to spread the word, Jan. I've requested an account, and I'll definitely be getting involved with your project. This look like a great venture!

'Wrong Debates'

Posted: 10 May 2014 08:33 AM PDT

Gloomy European Economist Francesco Saraceno:

Wrong Debates: Paul Krugman has a short post on the Eurozone, today (I'd like him to write more about us; he has been too America-centered lately), pointing out that the myth of fiscal profligacy is, well, just a myth. in fact, he argues, the only fiscally irresponsible country, in the years 2000 was Greece. It is maybe worth reposting here a figure that from an old piece of this blog, that since then made it into all my classes on the Euro crisis: 

Fig1postmarch161

The figure shows the situation of public finances in 2007, against the Maastricht benchmark (3% deficit and 60% debt) before the crisis hit. As Krugman says, only one country of the so-called PIIGS  (the red dots) is clearly out of line, Greece. Portugal is virtually like France, and Spain and Ireland way better than most countries, including Germany. Italy has a stock of old debt, but its deficit in 2007 is under control.
So Krugman is right in reminding us that fiscal policy per se was not a problem before the crisis; And yet, what he calls fiscal myths, have shaped policies in the EMU, with a disproportionate emphasis on austerity. And even today,... continued fiscal consolidation is taken for granted. I will write more on this in the next days, but it is striking how we aim at the wrong target.
