I have earned a research-based PhD in Economics from an accredited
Indian university and I have four years
of academic and administrative experience at university level. Could
you please advise me on acquiring a second PhD from accredited
American and British universities, on part-time or short residency
basis, where my education and experience are
credited towards the fulfillment of the award of the degree?

Dear Sir,

I'm afraid that the knowledge required to adequately answer this
question is just too uncommon. I wish you the greatest success in your
career.

I don't think that the knowledge is "too uncommon" but that I find it
hard to believe that any department would accept a PhD candidate that
already has a PhD in the field. PhD is a terminal degree, and
afterwards a person is supposed to try to find a postdoctoral teaching
or research position.
