He passes the "baccalaureat" in the city of Hälsingborg.

Bertil Gotthard Ohlin is born in Klippan, a village in the South of Sweden.

He serves for one year as assistant secretary to the Economic Council.

He becomes a professor of economics at the Stockholm School of Economics, succeeding Eli Heckscher. In 1929 he debates with John Maynard Keynes, contradicting the latter's view on the consequences of the heavy war reparations payments imposed on Germany. Keynes predicts a war caused by the burden of debt, Ohlin thinks that Germany could afford the reparations.

Having read in a newspaper a review of a book about the economic aspects of the world war – written by Eli Heckscher, who is then professor at the Stockholm School of Economics – he takes up studies there. He gains his M.Sc. in 1919.

Bertil Ohlin dies in Vålådalen, Sweden.

Bertil Ohlin shares the 1977 Nobel Prize in Economics with James E. Meade "for their pathbreaking contribution to the theory of international trade and international capital movements". Ohlin has contributed to the Heckscher–Ohlin model and has derived the theorem that nations specialize in industries most able to utilize their mix of national resources efficiently. Today this has been largely disproved, yet it is still a useful framework by which to understand international trade.

In 1938, he becomes a member of the Swedish Riksdag (parliament). As he continues to teach at the Stockholm School of Business in the coming years, he has only little time for scientific work left. He is leader of the People's Party (a social-liberal party which at the time was the largest party in opposition to the governing Social Democratic Party) from 1944 to 1967. He serves briefly as Minister for Trade from 1944 to 1945 in the Swedish coalition government during World War II.

In 1925 he becomes a professor at the University of Copenhagen.

He spends a year at Harvard University, gaining the degree of M.A. in 1923.

He receives his doctor's degree from Stockholm University in 1924. During this time he works for the State Tariff Committee.

He spends a year of military service in the Swedish Navy.

He studies mathematics, statistics and economics at Lund University and receives his fil. kand (equivalent to a B.A.) in 1917.
