Longwave (3): Roy G. Biv


Heck, I dunno. I do graphs with years on the horizontal axis and debt on the vertical.

I wanted to do a graph showing the relation between debt-per-dollar and Shiller's interest rate. Sort of like the Phillips Curve graphs that put inflation on one axis and unemployment on the other. No axis has years. I had to organize the data and create the graph a few times before I got a decent result.

Only decent. I was hoping to get pop-ups that identify the year of each point on the graph. Couldn't get that to work.

I did manage to break up the dots into color-coded chunks by date, as you can see.

Graph #1

Thing of it is, I don't know what to do with that graph. I have more confidence in my years-on-the-x-axis graphs. Like this:

Graph #2

But maybe something will turn up.

    Just so you know. Nick Rowe has been having problems with his comment section. You may have been caught in a spam filter. He actaully did a post on it a couple days ago. You might try again.

    Ill say that Nick has a pretty thick skin and doesnt take comments down very often. Yours probably got lost.

  2. I'd say that both graphs strongy suggest tht there is no relationship between debt/dollar and interest rates.

    That, in itself, might be worth knowing.

  3. I would expect that the relationship would be between the rate of change of debt per dollar and interest rates.
    i.e. something like: "when rates are low, debt is easier to make and so it accumulates faster." So maybe look at that instead?
    I guess that I would do yearly percentage growth in DPD (maybe averaged over some small period of time (3 years? don't know) just to make it less noisy).

  4. Interest rates peak first; DPD peaks later. Twice, that I know for sure.

    So if there is any cause and effect, Interest rates are the driver. But with lags >> a decade, that will be a hard case to make.

The spam filter's been acting up again lately. I'm aware, and checking it often.
Oh, what fun they must have with this at Blogger!
