From 1942 Robbins worked largely on planning for post-war reconstruction, with Meade. When John Boyd Orr and Frank Lidgett McDougall successfully lobbied to put food security on the agenda of the United Nations, Robbins attended the resulting 1943 conference at Hot Springs, Virginia. He represented the United Kingdom also at the Bretton Woods Conference of 1944, and took part in the negotiation of the 1946 Anglo-American loan. Over this period he became fully reconciled with John Maynard Keynes.
