This is a little tricky! Actually, "economy" is the not the subject of the verb "have been thought." The subject of "have been thought" would actually be the "empty it" here. See this post:

But yes, it should be "has been," such as in:

"It has been previously thought by some analysts that the economy is weak."

Hi Mike,

As explained by you about the choice C that "have been previously" is a passive and rarely used in GMAT.

However,i see another reason for it.The word "Economy" is a singular subject which would require a singular verb "has"(in this case).

In that case "claims suggest that economy might not be as weak as has been previously.......

Please review my explanation so that i could note it down for reference.

Thanks
