Krugman on productive silliness, economic models

[koganbot]

Always meaning to post more, and also need to comment on a shitload of things (three Mark Sinker threads need more input from me — Inuit tech, Oasis, hallway-classroom [UPDATE: Sinker links added] — not to mention what I owe Mark behind the scenes). In the meantime, here are links to four five blogposts from Paul Krugman on the use of models. Krugman's saying that to understand anything about economies you have to make simplifying assumptions, simpler often being better as long as (1) the models still tell you something useful and (2) you know when life is telling you to turn 'em off or rethink 'em. Subtheme is that, according to Krugman, many conservatives do this absolutely backwards, that is, refuse to turn off the microeconomics model as the supposed source from which all macroeconomics must derive, while at the same time decrying macroeconomic models that could save billions of people suffering and millions of lives if policy makers would act on them.

Dare To Be Silly

Too Much Faith In Models, Capital Taxation Division

Economic Realism (Wonkish)

Jean Tirole and the Triumph of Calculated Silliness

The State of Macro, Six Years Later [UPDATE: Added this link here (it's the "Subtheme" link above) because Krugman states his concerns more emphatically than he had in his previous post]

The New Economic Geography, Now Middle-Aged [UPDATE: Added this link here, and here's where I originally discussed it]

Also, there was this, from me:

Neither rational nor irrational

The discussion with Mark, if I ever have time for it, would include my own justification for my simplifying assumptions (hallway-classroom, for instance; also, the Rolling Stones and call-and-response, also jocks-burnouts-and-sometimes-freaks) and where he and I need to create more of them.

I've no idea how the smorgasbord of cultural appropriation plays out in Bulgaria, but it seems that those who pay attention to the cultural politics of Bulgarian pop think that chalga is trash anyway.

The sax riff quotes this cod-Japanese synthpop song, hence the florescent colours, mock-Oriental font and cute Asian girl styling. But, this being sexy Bulgarian pop-folk, cute little Ani doesn't forget to show some thigh and flash her panties -- not for lolicon appeal but to reassure Bulgarian men that she's really all woman.

Turning back to real Asian pop, the strawberries remind me to mention Crayon Pop's first subunit, Strawberry Milk.

No prizes for guessing who the members are.

First I've heard the term "chalga." I'm amused (or bemused) by the word "folk" being so prominent in its definition. I'm sure precommercial music is in its ancestry just as precommercial Anglo-Afro-American music is in Britney Spears' ancestry (and precommercial Anglo-Afro-American music is likely in chalga's ancestry too, though these elements probably register as "pop" and "dance" to listeners and commentators). But am I right in presuming that in chalga there's also a thing of "We are sounding like Eastern Europe"?

Strawberry Milk reinforce my conception of Crayon Pop methodology as "What color shall we paint our house this week?"

Favorite track on the mini-alb is "Feel So Good," which hops aboard the Austral-Romanian Choo-Choo at its Australian end.

Was going to post something there about how impressed I was by the track's being rigorously built around a repeating four-bar chord pattern, with but an occasional one-bar rock chord thrown in for emphasis, and a four-bar switch for the prechorus. (Assuming I'm correctly figuring out what's the chorus and what's the prechorus.)
