Among the major categories of international transactions, perhaps none
is usually farther from the limelight than unilateral, or unrequited,
transfers. This obscurity is puzzling, because countries' net receipt
s or payments of unrequited transfers often exceed their international
balances on both trade and current account and sometimes amount to si
zable fractions of their national incomes, and maintaining equilibrium
in international payments in the face of sizable transfers is a chall
enging issue. This article discusses the singular nature of unrequited
transfers, recalls an historic, and still relevant, controversy over
their economic impact, and recounts an effort by the United States to
neutralize their balance-of-payments consequences. The size of these t
ransfers in recent years, and some plausible explanations for them, ar
e then evaluated, with most attention given to those of the United Sta
tes.
