In talking with an old friend, we came up with a pretty cool economic equation.

He was going over some econ homework, and asking me for help.  He didn’t know what MPM stood for, and while it was marginal propensity to import, my mind was in the gutter.  Marginal propensity to masturbate.  

A new econ equation = change of frequency of masturbation depends on the change in price of porn.

MPM = d(M)/d(p)

I like it.

Yess I know I haven’t posted in a while…goodness!  So preoccupied with work and with this class at Harvard.  Can someone tell me how linear algebra applies to the study of economics?  I don’t think I’ll ever explain supply and demand through an orthonormal matrix.  

So here’s an update – I’d like you to navigate to discuss.roguelynn.com, maybe share some ideas and whatnot.  You’ll have to sign up but it’s cool.  

Also – the new book for the b-con book club is Paul Krugman’s “Return of Depression Economics and the Crisis of 2008.”  So far the first 30 pages or so are an easy read.  Right now I’m reading about the Latin American currency crises, specifically Mexico.  It’s kind of interesting how he reflects about the restrictions for foreign investors, how they discourage it.  I remember a few weeks ago there was an issue with Citibank’s presence in Mexico, and how the increase in government shares would be against Mexican foreign investment policies, having a foreign government hold more than 5% (?) of a company.  Clearly Citi broke that – I wonder how the bank and the government went about approaching the matter.  …I need to remember to look that up.

Hmm what ideas could I write about?  Any help out there?
