Bør Børson jr. is a satirical novel from the boom period during World War I, written by Norwegian writer Johan Falkberget.

Sea transport was a risky business that cost the lives of 2,000 Norwegian seamen, but a volatile stock market could multiply investments over short periods of time.

[citation needed] When Falkberget wrote a sequel called Den nye Bør Børson jr. for the magazine Arbeidermagasinet in 1927, he set the condition that the story should not be issued in book form.

[1] The story was adapted for theatre by Toralf Sandø, who also played the title character with the touring ensemble Falkbergets Teater from 1929.

[4] A musical by Harald Tusberg and Egil Monn-Iversen was staged at Det Norske Teatret in 1972, with Rolv Wesenlund as Bør and Britt Langlie as Josefine.
