Economics Roundtable

NOTICE 9/30/177

The Economics Roundtable website has been up and running for a couple of days now. Further periods of testing will be necessary. The RSS feed is still not working. The left sidebar links are also probably not updating correctly.

The problems were caused by updates to the programming language php and to the Apache operating system. It is taking time to track down the problems this causes with my system. - Bill Parke

Yeah, it's not just "good for you"

Here's how things stand: the stimulus bill is way too small, it's floundering in the Senate, and we stand possibly on the edge of a deflationary abyss.

Solution: find, say, the 5 most wavering Republican senators and offer ...

If you believe in a NAIRU, or anything remotely like a NAIRU or an accelerationist Phillips curve, the prognosis for prices is looking increasingly ugly. For those who believe confidently in such a Phillips curve and accept historical estimates of the parameters, deflation is now a certainty, and ...

Following up on my last post concerning Nick Rowe's application of rational expectations to public policy: it occurs to me that the way to look for evidence of policy effectiveness is to find cases where policy was, in retrospect, irrational. In other words, look for cases ...

Why is it that so many economists assume that private agents are rational but policymakers are irrational?

Breaking with that rather silly custom, Nick Rowe (hat tip: Mark Thoma) applies the rational expectations concept to policymakers and reaches the conclusion that we will never be able to ...

In a blog post a couple of weeks ago, Paul Krugman presents a scatterplot of the change in the inflation rate (y) as a function of the output gap (x), with the following regression line:

y = 0.5228 x - 0.4739

I'm puzzled as to why he includes ...

Reading Karl Smith’s comment on my previous entry, I started to think about the implications of rational expectations in the context of potential deflation. I’m thinking of a model like “Rational Expectations meets Calvo Pricing meets the Keynesian Multiplier meets the Mundell-Tobin Effect.” It goes something like ...

But then why is it letting me make this post?

UPDATE: OK, it seems to have reappeared. Maybe Google temporarily "deleted" it because I hadn't logged in since they changed their privacy policy? Or maybe they are in the process of deleting it and some things ...

It certainly seems to be functioning as an effective spam collector.

Maybe I should actually try posting something again.

It appears now that the G-20 intend to make their compromise with the devil. That’s pretty much inevitable, since the devil is one of them. When I say the devil, I am of course referring to the nation that invented the automobile (hint, President Obama: not the ...

OK, so I decided to do a substantive post – something I haven’t done in a while because this blog has fallen into the category where, if I have the time and energy to do this, then I also have the time and energy to do something more useful, so ...
