Econometrics Haiku

Here are some Econometrics Haiku from noted econometrician Keisuke Hirano.

Supply and demand:
without a good instrument,
not identified.

I relate to these especially:

T-stat looks too good.
Use robust standard errors--
significance gone.

and

From negation comes
growth, progress; not unlike a
referee report.

My favorite one is this ...

Testing restrictions:
Wald, Lagrange Multiplier,
Likelihood Ratio.

Here is mine. I hope it is truly original.

Look, binary Y.
Use Logistic Regression.
Goodbye helpful graphs!

to recurse, divine."

Ode to Utility

there is no way to tell, precisely

why thy curves slope down so nicely;

but we can judge, through observation

the marginal rate of substitution.

English Haiku are
stupid; Japanese words have
lots more syllables.

A literal Japanese translation, with the copula dropped (note that nn and tt are syllables):
eigo no haiku ha [6]
bakashii. nihonngo no tanngo ha [13]
motto onnsetu ga ooi. [11]

英語では
俳句何って
ものが無い

Utility,
Marginally diminishing
The stillness of equilibrium

Time,
Irreversibly moving forward
The music of learning

Knowledge,
Marginally piling up
The explosion of growth

Nice one, Kerry!

Prove the fallacy of econometrics.

1. Econometrics is mathematical history.
2. Mathematics is a priori knowledge.
Therefore,
3. Econometrics is a priori history.
4. A priori history is a fallacy.
Therefore,
5. Econometrics is a fallacy.
