Indeed.  I meant no disrespect to the economists!  I'm likewise forced
to make decisions with insufficient data in my line of work, and many of
my colleagues routinely consider 3 replicates to be a sufficient sample
because "Its enough to calculate a standard deviation with".

Perhaps I should have underlined that 
economists do this ... with the aid 
of a so-called indicator series 
at the higher frequency. Thus any 
inferences, or implications, that this is "making it up" 
are going too far. Like many statistical 
procedures, it is a matter of doing the 
best you can with the data you have.
