"We were conscious of a great sense of excitement about the plan. Marshall himself was a great, great man — funny, odd but great — Olympian in his moral quality. We'd stay up all night, night after night. The first work ever done that I know about in economics on computers used the Pentagon's computers at night for the Marshall Plan. I had a tremendous sense of gratification from working so hard on it."

“The monetary history of the last four hundred years has been replete with financial crises. The pattern was that investor optimism increased as economies expanded, the rate of growth of credit increased and economic growth accelerated, and an increasing number of individuals began to invest for short-term capital gains rather than for the returns associated with the productivity of the assets they were acquiring.

Free riders are perhaps more noticeable in this area than in the economy, where a number of rules in trade, capital movements, payments and the like have been evolved and accepted as legitimate. Free ridership means that disproportionate costs must be borne by responsible nations, which must on occasion take care of the international or system interest at some expense in falling short of immediate goals. This is a departure from the hard­ nosed school of international relations in political science, represented especially perhaps by Hans Morgenthau and Henry Kissinger, who believe that national interest and the balance of power constitute a stable system.
