David Glasner as poet

Romer’s most effective
rhetorical strategy
is to point out that

the core of modern macro posits
unobservable taste and technology shocks
to account for fluctuations in time-series data,

but that these taste and techno shocks
are themselves inferred
from the fluctuations in times-series data,

so that the entire structure of modern macro is
little more than an elaborate, sophisticated exercise
in question-begging.

I looked it up. Begging the question means the argument is circular.
