Krugman and Electricity Yet Again

In this post I argued that Princeton Economics Professor and New York Times columnist Paul Krugman was being misleading on the California energy crisis. I pointed out that the California electricity crisis had a number of factors that lead up to the market melt down starting around August of 2000, and that the problems were known to people in the business prior to the meltdown.

Well, via Brad DeLong we have this PDF which is the Testimony of Frank Wolak before the Senate Committee on Commerce, Science, and Technology.

What is interesting here is that Wolak is one of Krugman's sources, and Krugman points to Wolak when he talks about market manipulation.

We're approaching the first anniversary of the sudden, unexpected end of California's energy crisis. I went way out on a limb, at least by journalistic standards, by saying that market manipulation was a key feature of that crisis. I have since been vindicated: arguments that people called leftist nonsense a year ago are now conventional wisdom.

But of course I wasn't a brilliant investigative reporter; I just knew enough to talk to the right people, and to understand what they were saying. Paul Joskow and Severin Borenstein were very helpful. But my most helpful source of all was Frank Wolak, the Stanford professor who also heads the CAISO market surveillance committee. (CAISO is the "system operator").

In a recent paper (which doesn't seem to be on his web site yet) Wolak offers a very nifty model to explain what was going on. However, as they say in the journalistic trade, he buries his lede: the model is in passing, amid a dense discussion of institutions and their reform. So I thought I would lay it out here, to give you an idea of how I think about the whole thing.--emphasis added (Link)

The problem is that in reading the testimony by Frank Wolak you see that he draws a very clear distinction between a firm using its own unilateral market power and market manipulation.

What is the difference? The difference is that every firm has unilateral market power to varying degrees. If you have lots of small firms each firms unilateral market power is minimal and has little to no effect on the price. Firms in a market where there are only a small number of firms in total will have a much larger degree of unilateral mnarket power. Further, that each firm will use its unitlateral market power to increase its profits (and this is normal and to be expected).

The major cause of the California electricity crisis was the unilateral exercise of market power by suppliers to the California ISO control area. A firm exercises its unilateral market power by withdrawing generating capacity from the market either by bidding extremely high prices for some or all of its capacity or by refusing to make a portion of its capacity available to the market at any price. The goal of both of these strategies is to create an artificial scarcity of energy in order to drive up the market price.

Now to the novice this might look like market manipulation. And in a way it is. Each firm is engaged in a strategy to increase the price of the good it is selling. It is gaming the market, in one sense manipulating the market.

Wolak continues,

It is important to emphasize that it not illegal under US antitrust law for a firm to exercise its unilateral market power. Markets not dominated by a small number of firms face sufficient competition to discipline the unilateral attempts of these firms to raise market prices. Even in a market with a large number of firms, each one will still attempt to exercise all of its available unilateral market power. However, in a workably competitive market, each firm will find it unilaterally profitable to withhold very little supply from the market because the price increase it achieves from withholding very little supply from the market is very close to the price increase it achieves from withholding a significant amount. This logic implies that the firm’s unilateral profit maximizing strategy leads it to exercise very little market power.

In other words, unilateral market power and use of such power is not in and of itself illegal under U.S. Anti-Trust law. In fact, if firms did not do this it could be argued that the upper management and executives should be fired for incompetence in not maximixing shareholder value.

Later Wolak writes,

Now I would like to make the distinction between the unilateral exercise of market power and market manipulation. As discussed above, the unilateral exercise of market power is equivalent to the firm using all legal means to serve its fiduciary responsibility to its shareholders to earn the highest return possible on their investment. Market manipulation does not have a generally agreed upon definition. However, most would agree than market manipulation implies intent to harm competition or market efficiency and certainly implies “bad” behavior on the part of the manipulator. However, it is virtually impossible to infer intent from a firm’s actions. Returning to my earlier example, how do we know if the intent of a power supplier in buying power in the day-ahead market and selling it the real-time market was to harm competitors, and not just attempt to serve its fiduciary responsibility to its shareholders? Unless the market participant tells us their goal is harm competition or market efficiency we cannot tell.

In other words, it is not at all clear that what was going on was necessarily market manipulation, or that every instance where unilateral market power was exercised was market manipulation. The key point is that the the firm that is manipulating the market intends to harm it competitors, whereas with exercising unilateral market power firms could simply be serving the fiduciary responsibility of their shareholders. In fact, if a firm is witholding electricity it could be argued it is helping it competitors if it succeeds in raising the market price. For example, suppose there are two generators, and generator A bids in 500 MW at $20/MW. Generator B witholds and bids in only 300 MW at $500/MW. If that bid is accepted the market clearing price is $500 for both generators. Generator B has not only enriched himself, but Generator A as well. Kind of hard to argue harm when your competitor is making so much money.

Now this does not mean that what the generators did should be condoned. I agree with Wolak that rules need to be put in place to prevent such abuse of unilateral market power. But it does highlight the way in which Krugman is in subtle ways misleading and deceptive.

Update: Some readers are having some difficulty here with this post. Perhaps I can simplify the issue. Exercising unilateral market power is not illegal. Market manipulation and price rigging on the other hand will usually bring in the law enforcement boyos. By his continual use of the words "market manipulation" and "price rigging", Krugman is giving the distinct impression of illegal behavior. While illegal behavior might have occured, Krugman's claims are considerably stronger than the claims by Frank Wolak, and pointing to Frank Wolak as support for his position is dishonest. Both to Krugman's readers, and to Professor Wolak.

The bottom line is that once again, Krugman's "source" doesn't back Krugman's claim. Subtle? Hardly. And quite intentionally misleading.

Posted by: Robin Roberts on October 28, 2003 12:55 PM

Not at all, Robin.

Posted by: Brian on October 28, 2003 01:05 PM

I agree with Brian, I think it is subtly misleading. After all, not many people would go out an look for Wolak's testimony and read it. It is boring for the most part.

As for it being intentional or not, I tend to agree with you there. After all, anybody with a modicum of economics training can see quite plainly that Frank Wolak is making a distinction between market manipulation and unilateral market power. Surely somebody of Krugman's intellectual ability should have seen the difference.

Posted by: Steve on October 28, 2003 01:21 PM

If you go back to the original column and try to read it with an open mind, you will see that he's not doing that.

Posted by: Brian on October 28, 2003 03:13 PM

False, Brian.

Posted by: Robin Roberts on October 28, 2003 03:42 PM

No, I'm right.

Posted by: Brian on October 28, 2003 04:12 PM

No Brian, you are wrong. For example near the end of the article Krugman writes:

When price-rigging is the problem, price controls actually increase supply...

This is true, but with Wolak's model there is no price rigging--i.e., there is not collusion going on. What you have is a situation where even a small amount of witholding can drive the price very high (Wolak himself points out how as little as witholding 5% could drive up prices 50%).

Krugman does write this,

You don't have to imagine Ken Lay and Dick Cheney sitting in a room, trading sneers, and chortling over the havoc they are wreaking (which isn't to say that this might not have happened!). All it takes is individual firms, acting in their individual self-interest.

But the problem is that this is not market manipulation nor price rigging. Market manipulation and/or price rigging would have Ken Lay and Dick Cheney sitting in a smoke filled room chortling. Krugman is mixing up his message by sloppy use of terms.

Krugman would have been perfectly fine to use the term market power. It wouldn't have changed the length of the article all, but it sure would have changed its tone. From one of something illegal was done, to these guys just took advantage of a golden opportunity...a golden opportunity provided to them by those meddlesome bureaucrats. Of course, Krugman can't do that because in an other article he said it wasn't the meddlesome bureaucrats.

For some reason it has never been cool to talk about what was really happening in California. When the crisis was in full swing, most commentators clung to a story line that blamed meddlesome bureaucrats, not profiteering corporations. When the crisis came to an end, it suddenly became old news.

Maybe our national faith in free markets is so strong that people just don't want to talk about a case in which markets went spectacularly bad. But I'm still puzzled by the lack of attention, not just to the disaster, but to hints of a cover-up. After all, this was the most spectacular abuse of market power since the days of the robber barons — and the feds did nothing to stop it.

First, the meddlesome bureaucrats did play a role, a very important role. They created this market very badly. The reason this marekt failed so spectacularly was because it was designed very badly and the profit maximizing companies took advantage of it. That last part should not be suprising as that is what profit maximizing companies do. Take advantage of situations that make profits.

Posted by: Steve on October 28, 2003 04:30 PM

What happened in California is that the wholesale market was deregulated while the retail market was still capped. My question is why did this happen? Was it venal or stupid? My second question is why do economists keep getting off point? Market manipulation is ad hominem - after the fact. The road blocks were removed long before Enron etal entered the picture.

Posted by: Sparky on October 28, 2003 05:51 PM

"Krugman is mixing up his message by sloppy use of terms."

There are two far more likely explainations. One is that, because he's writing for a general audience, he wanted to make this is as accessible as possible. The second is that some editor changed a word or two.

Posted by: Brian on October 28, 2003 06:05 PM

First, I don't believe the editor changed a word or two bit. Second, market power is phrase most (if not all) of his audience would understand.

Second, the point is that market manipulation is illegal, so is price rigging. By using those terms Krugman is suggesting something illegal was done. Wolak on the other hand has not gone anywhere near that far. In fact, he has argued that while illegal actions might have been taken, unilateral market power and the exercising thereof is not illegal. Big difference, IMO.

Try again Brian.

Sparky,

My guess, I wasn't involved in the designing of the market structure--I got into the biz right after that in 1998, was stupidity, or at least a lack of foresight and being too close to the issue. The utilities, for example, seemed very concerned about recovering their stranded costs fully. They probably also expected the ISO and FERC would handle such market power problems, or they'd be fixed before they became too large.

Posted by: Steve on October 28, 2003 09:17 PM

Oy vey. Let's try to take this a few steps at a time.

Are Wolak and the others federal regulators?

Posted by: Brian on October 28, 2003 09:39 PM

Gee Brian, why don't you tell me? It'll be good for you to look that information up.

Posted by: Steve on October 28, 2003 09:41 PM

Well, the impression that I've gotten is that they are state regulators, not federal regulators.

Posted by: Brian on October 28, 2003 09:43 PM

You mean...you don't know!?!?!

I'm shocked!

Posted by: Steve on October 28, 2003 09:45 PM

Oh, please, Steve. Stop being so asinine.

As far as I can tell, none of them are federal regulators. Do you have something that says something different?

Posted by: Brian on October 28, 2003 09:55 PM

Well, did you find out what kind of regulator (if he's a regulator at all) Frank Wolak is? C'mon, a little research should be a snap for you, you're still in college.

Posted by: Steve on October 28, 2003 09:57 PM

He's a state regulator.

Posted by: Brian on October 28, 2003 09:59 PM

Really, what agency?

Posted by: Steve on October 28, 2003 10:00 PM

CAISO or CAISMO, whatever the acronym is.

Posted by: Brian on October 28, 2003 10:02 PM

Really?

Actually, no he is not a regulator. He is the Chairman of the CAISO's Market Surveillance Committee. His position is more of an advisor position vs. a regulatory one. That is he makes suggestions, not regulations like say Commissioner Pat Wood at FERC or Loreta Lynch at the CPUC.

Posted by: Steve on October 28, 2003 10:06 PM

Well then, I was wrong, but I'm not worried.

Would you mind explaining this paragraph?

"Oh, but that's one little instance? Oh no, Krugman new about the problems in 1999 and even the problems in 1998. Don't believe me? Click here


Does this really happen? A recent National Bureau of Economic Research working paper by Severin Borenstein, James Bushnell and Frank Wolak cites evidence that exactly this kind of market manipulation took place in Britain before 1996 and in California during the summers of 1998 and 1999.

Krugman is lying to you...blatantly and openly. See, in 1998 and 1999, the electricity producers were manipulating prices becasue Bush was going to be President.....errr yeah. That's the theory according the Krugman."

Posted by: Brian on October 28, 2003 10:08 PM

In the year 2000 (in December in fact) Krugman new that there was evidence there was a problem prior to the meltdown in August 2000. He referenced an NBER working paper from 2000 that provided this evidence that there was an exercise of marekt power (in 1998 and 1999). So when Krugman is implying that Bush was going to put the fix in for his energy cronies, the implication is that the fix (in terms of the election) was in back in 1999 maybe even 1998.

Does Krugman actually believe this? I don't know. He has become more wild eyed over the months. But it certainly is something he left dangling there for his readers to zero in on. Like I said, Krugman doesn't peddle cheap easy to spot lies. He doesn't say, "Up is down and black is white." Now, he'll dangle something like that out there for his readers to nibble at and maybe bite on. If called on it, he can always weasel his way out by saying, "Hey, I said it was just a conspiracy theory."

Posted by: Steve on October 28, 2003 10:20 PM

Okay, we'll go with that. So the problems in 2000 were as bad as the ones in 1999 and 1998?

Posted by: Brian on October 28, 2003 10:31 PM

Where did I say that?

Posted by: Steve on October 28, 2003 10:32 PM

I don't believe you've mentioned it in this particular part of the site, but answer the question.

Posted by: Brian on October 28, 2003 10:34 PM

Maybe you should make sure I have written it. Have you tried the search engine?

Posted by: Steve on October 28, 2003 10:37 PM

I'm doing a few different things right now. Just answer the question.

Posted by: Brian on October 28, 2003 10:38 PM

Oh you don't like it when I dance around your questions? Hmmmm....gee wonder where I picked that trick up.

How about this Brian, the answer is, no. 1998 and 1999 were not worse. In fact, I implied that when I wrote the market had a meltdown in August 2000.

Its like a car. You are driving along and the engine is getting hotter and hotter. You ignore the temperature gage. Then after several more miles your engine splutters, sputters and dies. The engine is basically ruined as it siezes up.

Not a perfect analogy, but pretty close for our purposes. 1998 and 1999 were when the gage was indicating things were getting to a problem point.

Posted by: Steve on October 28, 2003 10:42 PM

I didn't think you were dancing around the question, but rather, that you were mostly trying to imply that I was lazy for not using the search. Whatever.

So then, Krugman wasn't far off when he said that things exploded after the election in 2000?

Posted by: Brian on October 28, 2003 11:14 PM
So then, Krugman wasn't far off when he said that things exploded after the election in 2000?

Wrong again Brian.

Why don't you go the Frank Wolak's site and actually read some of his writings.

As I have tried hammering through your skull, things got really bad in August. So, are Presidential elections held in July?

Posted by: Steve on October 29, 2003 05:14 AM

Well, I don't remember seeing anything for comparing the situation in August to the situation right after the election. Perhaps, to an outsider, the situation looked like it really started to unwind after the election. But like I said, perhaps.

Now, what part of Wolak's testimony are you referring to in this particular instance?

Posted by: Brian on October 29, 2003 07:15 AM

You know Brian, Wolak has a site...with lots of material on there. You can find it on google.

Now, I could be a nice guy and point you directly to the PDF that has some interesting data, but given your inability to answer direct questions...I think I'll be the dick now.

Posted by: Steve on October 29, 2003 09:02 AM

I looked at that .pdf file that you listed above, but I'm not positive about what you are referring to in particular. That's why I asked.

Posted by: Brian on October 29, 2003 10:51 AM

Sigh....Brain,

I'm not trying to be a jerk here, but damn your own inability to try and learn and improve yourself is very disheartening.

Here is Frank Wolak's website

Here is a specific paper you should read

On that last one, please look at page 7. While the prices were indeed higher in December than in August, note that the market power measure (the right hand most column) is the highest in August of 2000 and the second highest month was June of 2000.

So it depends on what exactly you are looking at. In terms of prices, yes things were really bad in December in 2000, but from a market power stand point they were worse in August and June. Further, there are additional details that could skew these results in favor of December in terms of the price that have nothing to do with the election. But as it is close to lunch I'll leave it to you to ferret these things out.

Posted by: Steve on October 29, 2003 11:19 AM

Do you have something that that describes power shortages, not price, which is what Krugman was talking about?

Posted by: Brian on October 29, 2003 01:37 PM

Sigh. You just don't learn do you Brian?

Yes, the shortages did get worse in the last few months of the year. Do you know why? I do, but let us see if you know the answer.

(By the way, I'm sure Frank Wolak knows too.)

Posted by: Steve on October 29, 2003 01:57 PM

So if Krugman claimed that, why does that make him a lair or a deceiver?

Posted by: Brian on October 29, 2003 03:19 PM
So if Krugman claimed that, why does that make him a lair or a deceiver?

You gonna answer the question I asked?

Nevermind, I know you don't know.

Here is the answer: The reason that there were more blackouts/shortages/emergencies was that the utilities basically stopped paying the generators. A substantial number of these generators are what are called qualifying facilities (in the energy biz they are called, 'QFs'). These are small, usually green power, facilities. When they stopped getting paid, they basically stopped generating. This exacerbated the situation and resulted in the shortages. Now, you might say, so? They are small, how much can they account for in terms of generation capacity in CA? How about 1/4th? Now, does that sound like alot? Does to me.

Now...how do I know this? Well, if you look over on the right of my blog. Yes, there where the links are. Scan down till you come to the Energy links. See it? Good. Now, do you see the one that reads:

C-A-L-I-F-O-R-N-I-A E-N-E-R-G-Y C-O-M-I-S-S-I-O-N?

Well, there you go. Just a few mouse clicks away is knowledge.

Anyhow, getting back to Krugman; we need no conspiracy. No big generators taking even more plants offline. No need to bring in the specter of Dick Cheney.

So how does this make Krugman deceptive? He writes the conspricay theory and then leaves it hanging out there after telling us he knows which experts to call and they confirm his suspicions. It is a carefully crafted bit of bullshit that he can deny any responsibility for. After all is it his fault that his readers are so trusting of him? Is it Krugman's fault if his readers misread what he has actually written? I say it is because that crap was totally unnecessary.

Tell me Brian, do you believe there was a grand conspiracy to rip off the state of California?

Posted by: Steve on October 29, 2003 03:56 PM

"You gonna answer the question I asked?"

You were trying to change focus to a different part of the subject.

You've admitted that things did get worse in the last few months of the year, which is what Krugman claimed. What is the problem?

Posted by: Brian on October 29, 2003 07:25 PM
You've admitted that things did get worse in the last few months of the year, which is what Krugman claimed. What is the problem?

The problem is that Krugman's assertion (one even he probably doesn't believe) was groundless. Further, if he did have a nice long chat with Prof. Wolak, he probably knew this. In other words, he tossed out a bullshit story, one that he quite possibly new was bullshit, and then left it out there. That is irresponsible and deceptive. There was no need to invoke a conspiracy at all...none. Lets run through the time line, okay.

In May of 2002 Krugman describes Wolak's model and notes you don't need a conspiracy.

In September of 2002 once again going back to Wolak, Krugman again discusses market power (calling it market manipulation) and this time casually tosses in the conspiracy theory and then fails to debunk it as he did in May.

You don't see this as deceptive Brian? I do. As you note, Krugman tries to write for the layperson. It is not likely they are going to go find Wolak's work (you didn't) and they are not likely to even try to figure out what a non-cooperative Nash equilibrium is.

By the way, even in non-cooperative games, you can still get collusion. Its called tacit collusion. Trot your butt down the school library and find Jean Tirole's book on industrial organization. Look up tacit collusion and read about it. It is the result of a non-cooperative game. Tacit collusion is illegal. Tacit collusion is a non-cooperative result. So in a technical sense Krugman even blew that.

This is the same problem with the employment data. Its looking like Krugman picked the series he did so he could make his "since Hoover..." claim and for no other reason. Then he portrayed that series as being total civilian employment. Only by looking carefully at what he wrote, reading down into the minutiae of the last BLS Employment Situation Report was I able to figure out what was going on. Do you think the general lay person can do this? You can't even click in a frigging link on my website to better prepare youself to discuss electricity with me, and you are apparently studying economics!

Robin has brought up the issue of the Secretary of the Army and the dubious e-mail. So now we have three instances of Krugman being at the very, very best being deceptive. At worst he is being deliberately dishonest.

Posted by: Steve on October 29, 2003 09:11 PM

At least at one time, Krugman had the academic discipline to work at this level. Its obviously intentional on Krugman's part.

There was no need to invoke a conspiracy at all...none. Lets run through the time line, okay."

You've already admitted that the situation was worse in the final months of 2000, so again, how is Krugman wrong in making such a claim?

"In May of 2002 Krugman describes Wolak's model and notes you don't need a conspiracy."

Where?

"You don't see this as deceptive Brian? I do. As you note, Krugman tries to write for the layperson. It is not likely they are going to go find Wolak's work (you didn't) and they are not likely to even try to figure out what a non-cooperative Nash equilibrium is."

You haven't proven that he's been deceptive.

"In September of 2002 once again going back to Wolak, Krugman again discusses market power (calling it market manipulation) and this time casually tosses in the conspiracy theory and then fails to debunk it as he did in May."

You're not making sense. He merely explored the possibility of wrongdoing, among other things. What did he fail to debunk?

"This is the same problem with the employment data."

"You can't even click in a frigging link on my website to better prepare youself to discuss electricity with me..."

That's inaccurate.

"At worst he is being deliberately dishonest."

No.

No.

How can you make such a comment?

Posted by: Brian on October 29, 2003 09:59 PM

Brain,

It is time you grew up. You are acting like a child. Go read his articles on electricity from May of 2002 and September of 2002. I have links to them in various posts. I have quoted the relevant sections. It is not my fault you have nto read Krugman and/or cannot retain/recall what has been discussed before.

Krugman basically floated this notion of a conspiracy which previously he had indicated was not at all necessary. This is an indisputable fact.

You're not making sense. He merely explored the possibility of wrongdoing, among other things. What did he fail to debunk?

Read what I write. It is quite clear.

May 2002: Krugman describes Wolak's model, notes you don't need a conspiracy. Link

From the article:

The really striking thing, of course, is that there is excess capacity in the system - yet the price goes sky-high. And with a little realistic friction added, you could easily imagine blackouts and brownouts as part of the picture. Let me also stress that this is a non-cooperative equilibrium - it doesn't involve collusion, let alone conspiracy, among the generators. You don't have to imagine Ken Lay and Dick Cheney sitting in a room, trading sneers, and chortling over the havoc they are wreaking (which isn't to say that this might not have happened!). All it takes is individual firms, acting in their individual self-interest.

September 2002: Krugman again returns to Wolak's model and this time tosses out the conspiracy, but instead of debunking it, moves on to another point. Link

From the article:

One answer might be that the apparent malefactors are very big contributors to the Republican Party. Some analysts have suggested that energy companies felt free to manipulate markets because they believed they had bought protection from federal regulation — the conspiracy-minded point out that severe power shortages began just after the 2000 election, and ended when Democrats gained control of the Senate.

As for the employment data the facts of the case point that you are idealogue who has trouble following logical arguments, understanding data, and doing basic research. The only data set for which Krugman can make his claim is the non-farm data set (series). He doesn't tell his readers that, instead he calls it "employment" giving the false impression it is total civilian employment.

I have also posted a note from a highly respected economist who takes Krugman to task for writing while "pissed off" and apparently who failed to research what he was popping off about.

These are all facts Brian. Verifiable facts. Yet you keep playing dumb. In fact, you have done such a good job of it, no I'm begining to think maybe you aren't playing.

I have quoted the relevant sections. It is not my fault you have nto read Krugman and/or cannot retain/recall what has been discussed before."

I thought it was a column, I went and looked in that section and didn't see anything. Now I see that what you were referring to was in another section.

"Krugman basically floated this notion of a conspiracy which previously he had indicated was not at all necessary. This is an indisputable fact."

Well, if you look at that column, it seems he was merely discussing what some believed.

As for the first link, did you not catch the following part? "...(which isn't to say that this might not have happened!)."

And in the second link, I ask you the same question: did you not catch this part? "But only in the last few weeks, with a series of damning reports and judgments, has conventional wisdom grudgingly accepted the obvious."

"As for the employment data the facts of the case point that you are idealogue who has trouble following logical arguments, understanding data, and doing basic research."

No.

"I have also posted a note from a highly respected economist who takes Krugman to task for writing while "pissed off" and apparently who failed to research what he was popping off about."

I don't remember this controversy as well as I would have hoped, but I did go to pkarchive.org and found this: www.pkarchive.org/cranks/Brian.html

It seems like the "pissed off" remark was taken out of context, even to a slight degree.

"These are all facts Brian. Verifiable facts. Yet you keep playing dumb. In fact, you have done such a good job of it, no I'm begining to think maybe you aren't playing."

I do like the fact that you felt it was necessary to insult me.

Brian, that was another entry in your "Pot meet Kettle" contest? After all, you are the one posting "Steve is an idiot".

Well, if you look at that column, it seems he was merely discussing what some believed.

Correct, he is tossing it out there and then leaving there. Even when he knows it is totally un-necessary to obtain the types of results we saw. The truth is probably more messy. There probably was some levels of collusion and most of the behavior was simple rational profit maximizing behavior without collusion.

Let me demonstrate. In a perfectly competitive equilibirum every single firm charges the exact same price. Is this collusion? No, absolutely not. Seeing similar behavior in firms is absolutely not evidence of any collusive behavior. Any undergrad in economics should be able to articulate this idea. A professor of economics at Princeton with a PhD from MIT should also be able to articulate this idea.

"But only in the last few weeks, with a series of damning reports and judgments, has conventional wisdom grudgingly accepted the obvious."

Have you even bothered to read Frank Wolak's stuff? He is the expert not Krugman. Wolak is not saying this, and he sees far more of this information/data than Krugman does. The above is semantical bullshit. Right now FERC is going through that information and trying to figure out what was illegal and what wasn't. Some of it probably was, but not all of it. Further, there didn't need to be a conspiracy with the White House.

Have you heard of the concept of parsimony Brian? It means your model should have no unnecessary variables in it. A similar concept is Ockham's Razor, which holds that unnecessary variables should not be added to a model. Another version of it is, explain alot with a little. The conspiracy angle is an unnecessary variable.

Regardin Arrow:

But Nobel laureates, who have wide responsibilities and much on their mind, are not necessarily on top of what has been going on in research outside their usual field.

Did you read that Brian. If we are to believe Krugman we should conclude he doesn't know what he is talking about when it comes to electricity. Now, if we don't believe this, then the Arrow letter stands on its own. So, I'll let you pick.

I happen to know of one laureate who, circa 1991, was quite unaware that anyone had thought about increasing returns in either growth or trade. Did you try talking to anyone else--say, to one of the economists who are the straight men in the stories you tell? For example, your book starts with the story of Arthur's meeting in 1987 with Al Fishlow at Berkeley, in which Fishlow supposedly said, "We know that increasing returns can't exist"--and Arthur went away in despair over the unwillingness of economists to think the unthinkable. Did you call Fishlow to ask whether he said it, and what he meant? Since by 1987 Paul Romer's 1986 papers on increasing returns and growth had started an avalanche of derivative work, he was certainly joking--what he probably meant was "Oh no, not you too."

Here we have Krugman the asshole mind reader. Christ what an insufferable jerk.

In fact, that page looks like Krugman basically complaining, "Why wasn't an article written about me."

"The above is semantical bullshit."

Oh, really?

"The conspiracy angle is an unnecessary variable."

Maybe, maybe not.

"If we are to believe Krugman we should conclude he doesn't know what he is talking about when it comes to electricity."

I did read that, but you're not applying that quote correctly.

"Here we have Krugman the asshole mind reader. Christ what an insufferable jerk."

Nonsense.

"In fact, that page looks like Krugman basically complaining, 'Why wasn't an article written about me.'"

In some ways, that's a somewhat fair statement.

Oh, good grief.

Hi. I'd like to have an argument with you. I'm sure I'm right, but in order for me to win, I'll have to back my assertions with some fact. Do you mind telling me where the facts are, and while you're at it, help me with my arguments?

If you don't, I'm going to just disagree with you relentlessly until you give in.

Thanks.
