Unless I’ve unfairly overlooked someone, it looks like no recalculationist answered
my original question – namely, “By what percentage do real GDP and
employment fall if nominal GDP unexpectedly declines by 5%?”  Arnold comes the closest.

In this example, I would have to say that a standard monetarist-Keynesian synthesis gives the correct answer.

Yes, the standard monetarist-Keynesian synthesis might have a standard range of responses.  However, I’m asking recalculationists to answer my question with the specific number they believe to be true.  Who will indulge me?
