Home, sweet home equity

10 Oct 2007 12:16 pm

In the comments to my previous thread on home equity and mortgages, Cactus defends the notion that, once again, electing any president who is a Democrat has special, magical effects on desireable economic variables such as the amount of equity people have in their homes. The problem with this, as with most of Cactus' other demonstrations of amazing Democratic presidential economic power, is that it gives us an Underpants Gnome theory of economic good:

1) Elect anyone who is a Democrat to the office of president

2) ???

3) Awesome economy!

In the case of housing, however, this is particularly useless, since we already know what variables drive home equity:

1) How much you can affordably borrow against your house.

2) How much inflation is eroding the value of the money you have already borrowed against your house.

3) The value of your house

We also know, to a first approximation, what has driven these changes over the last fifty years:

1) More sophisticated credit rating systems

2) Increased global capital flows

3) The shift towards house financing via long-term amortizing mortgages following World War II

4) The growing trend towards securitization of mortgages

5) Changes in federal reserve policy that caused inflation to accelerate in the mid-to-late 1960's, then decline post-1981 as the Volcker Fed finally cracked down

6) The market reaction to above, which resulted in slow secular decline in interest rates from the 1980s to today.

7) Changes in the relative tax preference for housing-secured debt in 1986, which caused homeowners to prefer mortgage debt over other forms of consumer borrowing.

8) A slight rise in homeownership, particularly in recent years; first time buyers tend to be unusually debt-heavy.

Some of these things are affected by presidential policy, but most aren't, and moreover, those that are will almost never show significant variance within the term of the president who enacted the policy. That's because home equity is a stock, not a flow; except for inflation, any significant change in the amount, or terms, of new debt will take years to show up in the home equity figures.

For example, Lyndon Johnson's privatization of Fanny Mae, and Carter/Reagan era bank reforms undoubtedly enhanced the securitization trend, but mostly decades after they left office. Likewise, the breakdown of Bretton Woods ultimately gave us the global capital flows that so boosted the mortgage market in the 2000's, but made little difference during his own time. The one presidential policy that can reasonably be said to have enhanced home equity while those presidents were in office was the great inflation of 1966-1981. But since the side effect of this laudable boost in home equity was the slow-motion implosion of our economy, I'd hardly rush to take credit for that.

cactus seems hell bent on a program to destroy the credibility of the UCLA econ Phd program, all by himself.

Jane,

PRS - that's why everyone argued for him not to link Angry Bear with his consulting business homepage.

"Elect anyone who is a Democrat to the office of president"... "Awesome economy!"

Where did I ever write something like that? I've noted that on most big economic series, since Ike, Dem Presidents have done better than Rep Presidents, on average. (We can, of course, get into "why not go back to FDR" again, but I don't think that needs rehashing.)

But that hasn't been true of every series. And not necessarily true of every Dem President and every Rep President. (Carter often doesn't rank in the top 3, and sometimes neither does JFK/LBJ. On a few series, all of the Dems look bad.) I've merely put the data out there. I do try to comment - sometimes the commentary is better, sometimes its worse.

But I've noticed... the criticisms I used to get in the beginning were that the results were due entirely to selectively picking series. As I've continued adding series (pretty much everything I can find, from abortion rates to the economy), the accusation has shifted to one that I've got some sort of a pro-Dem bias.

I'm not exactly a raving dem... as I've noted before, time and again, I think the best thing that can be said about the dems right now is that they're marginally less offensive than the reps. If that's bias, so be it. But Stephen Colbert is right, the fact have a liberal bias. Not all of the facts, but the data shows what the data shows.

Wouldn't "what the data shows" tend to be largely dependent on what you assume about time lags?

Cactus, come on. You've repeatedly stated that you think there's a causal link . . . and repeatedly declined to identify any causal link that's vaguely plausible, other than some variant of "Democrats care" or "Democrats are responsible" that are both highly debatable, and distinctly non-testable propositions.


My criticism is that you're not testing a mechanism; you're testing a highly irregular sample with an N of 10, with variables that aren't independent, indeterminate lags, highly plausible reverse causation, and no real consistency, other than the name, between presidents bearing the labels "democrat" and "republican". That remains my criticism. Your answer to which has so far been "But look at all the pretty correlations!"

Megan,

Aren't you missing at least a couple of variables with respect to home prices? For example immigration (and population growth more generally) and, in certain metro areas (e.g. New York City), foreign buying, driven partly by the declining dollar?

Fred: I imagine those would fall under "the value of your house".

"My criticism is that you're not testing a mechanism; you're testing a highly irregular sample with an N of 10, with variables that aren't independent, indeterminate lags, highly plausible reverse causation, and no real consistency, other than the name, between presidents bearing the labels "democrat" and "republican"."

OK. But that implies I've run a test or claim to be running a test. And I have done that in some posts in this series where the President's actions have a more direct consequence to series' outcome. And in a few instances, I've tested factors that been important (e.g., real MS) But where is the test in this post you reference? What part of the post could be interpreted as a test of Dems v. Reps?

Okay, so you're retracting any and all claims that there might be a causal relationship between who holds the presidency and the state of the economy?

Wow. Megan McArdle makes all sorts of claims. Serious criticisms are and have been made about the evolving series by good conservatives who visit the blog over time. Too bad you are not serious.

Wow. That straw man totally got his ass kicked!

Whoa, are we talking about home equity here, or global warming?

Wait, you have a sample set of 10 instead of 1, I guess home equity then.

The series cactus offers answers the question are we better off with Democrats in office or with Republicans in office. The answer, which interestingly enough conforms with most peoples preconceptions, is that we are, by most measures, better off with Democrats.

Megan is asking why this is so, a question that cactus does not address.

Perhaps it is just because reality does indeed have a liberal bias.

How about adding a comparison of who has a majority in the House and Senate to your series? It might be interesting to see if there is a correlation with that and/or with whether or not the President and Congress were held by the same party.

Oh, and ken, speak for yourself, please.

From my point of view, so as not to speak for cactus, is that the series is strung out over many many posts, and has been re-worked and criticized by many persuasions and angles. It is not put together as a final word.

When a new addition is added it goes through a process, which Mary could aid or mock. The Ownership post is somewhat new.

The diffuculty with the blog format is that it calls for quick judgements, and is not conducive to longer projects of cooperative effort.

Quick hit points seem to count more than analysis in order to stand out from the crowd. We are all guilty of that.

Earnest Iconoclast,

How about adding a comparison of who has a majority in the House and Senate to your series?

I had a post on that, looking at real GDP per capita... as I recall, if you go from the year a party takes a majority to the year it loses the majority, Dem majorities do better at real GDP per capita, by quite a bit, than Rep majorities or mixed congresses. This is true whether the Pres is a Dem or Rep. If you look at from the year before a Congress takes over to the last year in office, if I recall correctly, results are the same regardless of which party in power. (Dems up by 1/10th of a percent or something like that.) My recollection may be off... perhaps its time to revisit.

Megan,

"Okay, so you're retracting any and all claims that there might be a causal relationship between who holds the presidency and the state of the economy?"

As I noted upthread...

"And I have done that in some posts in this series where the President's actions have a more direct consequence to series' outcome. And in a few instances, I've tested factors that been important (e.g., real MS)"

Since some of those tests (e.g., real GDP per capita, debt, etc.) had significant ts, why would I retract any and all such claims?

I am not going to defend Catus, he is an adult.

However, I am going to defend to the death the overwhelming results of his work that the Republican economic policies of trickle down economics do not work. What he has demonstrated beyond a shadow of a doubt is that the economic policies the libertarians and/or republicans advocate are a complete failure.

I challenge you to present any evidence that disproves this.
