Q. What was the name of the world currency that John Maynard Keynes conceptualized in the years 1940-42 and proposed at the Bretton Woods Conference?
Answer: Bancor
Notes: John Maynard Keynes proposed the "Bancor" as a world currency during the Bretton Woods Conference in 1944. The Bancor was intended to facilitate international trade and stabilize exchange rates. Keynes envisioned it as a unit of account to address imbalances in global trade. Although the Bancor was not adopted, the conference led to the establishment of the International Monetary Fund (IMF) and the World Bank, shaping the post-World War II economic order.
