Yes in the sense that in the absence of any 
other evidence I would have guessed the reverse. 

But a guess is just a guess. 

Can't you graph the data and think about them directly? If all 
states superimposed looks too much like spaghetti 
you can create a slide slow by something like this. 

Suppose your states are 1 to 50 with value labels. 

forval i = 1/50 { 
	tsline lnq5 lnmin1 lngap if state == `i', sub(`i') 
	more 
}
