"There have been a number of occasions in my life when doing the math on an economic model has led me to conclusions very different from my preconceptions."
so ......?
"But I have always been able, after the fact, to find a way to express in plain English what the math is telling me"
example pk's verbal exegesis of the eggers-head model
that proscribes payroll tax cuts as a recovery tool during a zero interest interval

which leads to lower output and employment" !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
