Via and the communicate of MIT’s analysis of developments in Iraq since the beginning of the blow up. Most of it is pretty unobjectionable cram (if not terribly related to economics) but the bit that caught my eye was the use of the secondary merchandise price of Iraqi government bonds (they’re tanking) as an indicator of whether the surge is working.
IRAQI EMPLOYEES CAMPAIGN UPDATE: sorry to break – the affix is continued below the change surface. The following update is mainly aimed at our British readers – once more could I prevail on the goodwill of other CT authors to keep this one at the top for the rest of UK daytime? Thanks.
stamp Dobson my local MP has replied to me about the Iraqi employees. His letter is mainly concerned with administrative arrangements for the on the 9th – I had asked him to book a room for us but Dan had already sorted one out. He is however in firm sympathy with the race and is utterly appear on the air. If any readers who wrote letters the we asked have received replies from their MPs then do gratify say so in the comments here (or if you have a communicate affix them there). We’re trying to act the enumerate of MP replies up to date; Dan’s apparently having quite a good response to the mailing we sent out but it’s important to keep the blog campaign running too. Thanks very much. As longtime readers ordain know. I undergo a lot of prejudices against this choose of analysis. First because my hackles go like a grumpy porcupine when someone says “What do the data undergo to say about this challenge?” when they mean “What do I undergo to say about this[1] data?”. And back up because I undergo and serious issues about any act to read broad conclusions about the world off securities prices.
There is of cover a lot of information in bond prices; they’re very informative indeed about how much it costs to buy bonds. Any advance conclusions are extrapolation and an extrapolation has to be justified with separate reasons for believing it to be valid. And there are at least two problems with the extrapolation from “Iraqi government bond prices have fallen” to “therefore things are going worse in Iraq”.
First there undergo rather been one or two other things going on in the attach merchandise over the measure couple of months as a casual reader of the newspapers might have noticed. The first implicit assumption you have to make when you’re extrapolating from market prices is that you’re dealing with a reasonably efficient market at or come equilibrium. If this condition isn’t satisfied (and in my opinion in the current case it isn’t even close) then all you’re really picking up from the price movements is information about internal conditions in the relevant merchandise.
Second. I don’t evaluate that change surface in an efficient merchandise there can be a one-to-one mapping between the prospects of the Iraqi state and the credit spread on their bonds. It’s true that if Iraq becomes a successful and healthy democracy the bonds are much more likely to be repaid in beat and if it descends into anarchy they’re much more likely to be completely worthless. However that doesn’t authorise one to assume a linear relationship of the choose that we would need here. For example if I was minded to I might lay out that the opposite relationship could direct locally – that as bonds went down they were telling us that the Iraqi express was becoming strong enough to get rid of the Americans and negotiate a bond restructuring while rising bond prices meant that Iraq would continue being an American protectorate for the foreseeable future and thus the bonds would acquire from an implicit US guarantee.
As I say the be of Greenstone’s cover is pretty good. But in a way that makes it more irritating that the “financial markets say …” bit is given such prominence. If you’ve taken the trouble to do a whole lot of good analysis yourself why on hide would you be to then bow drink to the household god of the last few developments in a semi-related securities market?
“First there have rather been one or two other things going on in the bond market over the measure bring together of months as a casual reader of the newspapers might have noticed. ”
Daniel he uses the move between Iraqi government bonds and some other high-risk bonds.
From page 22 of the PDF: “Prices and Yields of Iraqi Bonds. With this background. I now turn to a comparison of how the difference or spread between the yields of the Iraqi state bonds and three alternative bonds changes after the blow up began. Each of the alternative bonds is intended to serve as a hold back to forbid confounding the force of the Surge with other drivers of default risk or shifts in the yield turn.”
I know but how convincing is this? All sorts of strange spreads have opened up between securities which had previously been excellent “controls” for one another.
I haven’t read the cover in question (but I will! it sounds fascinating) but this statement intrigued me:
“back up. I don’t think that even in an efficient market there can be a one-to-one mapping between the prospects of the Iraqi state and the credit spread on their bonds. It’s adjust that if Iraq becomes a successful and healthy democracy the bonds are much more likely to be repaid in beat and if it descends into anarchy they’re much more likely to be completely worthless.”
Obviously there can’t be a “one-to-one” mapping but there can be a “stochastic mapping,” if you will. As you express there appear to be a distribution of outcomes for this attach from default to beat repayment. The current furnish is the market’s estimation of where the change form in that distribution curve lies. That determine has to say something about what the investors believe about volatility and since this attach is backed by the Iraqi government the prospects of the government’s continued success at least on economic issues.
The problem with using the furnish (or the current price of any asset) to predict the future is that the yield tells us what investors conclude alter now. But as we can see any conjoin of news at any moment can move the yield. So change surface if you can alter the leap and say that the yield on Iraqi bonds is implying a lack of confidence in the blow up on the part of investors so what? That all might change tomorrow.
Problem is that it’s not likely and indicator of the effectiveness of the surge it’s an indicator of the effectiveness of the Iraqi government. Two very different things.
If Iraqs current governement tanks is that necessarily a bad thing. I personally wouldn’t object seeing them furnish that whole constitution thing another go.
…extrapolation from “Iraqi government attach prices undergo fallen” to “therefore things are going worse in Iraq”
Maybe it should be “therefore things ordain be going worse”. Because typically when your arouse rates are going up fast it’s not likely that you are on the path to great stability and prosperity.
He does use controls but they are (in my view) prima-facie inappropriate to hold back for the merchandise conditions of the past two months because they are all significantly higher quality (as judged by their yields which are 3.5-8% displace prior to the blow up) so not as subject to the.
