Suppose, a country is facing deep-rooted economic mismanagement and has billions of dollars of external debts. The prime minister/president tried several local experts, both elected and technocrat, but they failed to deliver as expected.
The PM/president knows a country where a guy (say, Alexei Kudrin of Russia) became famous for single-handedly lifting a country's economy. He wants to put this guy in charge of the economy.
Can the PM/president borrow an expert from another country and put him in charge of a ministry?
