Trygve Haavelmo's Birth Card: The 5 of Clubs

In the record

Trygve Magnus Haavelmo (13 December 1911 – 28 July 1999), born in Skedsmo, Norway, was an economist whose research interests centered on econometrics. The birth-card coordinate for December 13 is the 5 of Clubs — a calendar position, not a forecast of the 1989 Economic Sciences prize.

The 5 of Clubs coordinate

Trygve Haavelmo's birthday maps to the 5 of Clubs (The Dynamic Innovator). Card Blueprints treats that as a 365-day coordinate: solar value = 55 − (2 × month + day), and the year is unused. It is not a prediction about a Nobel Prize and not a verdict on Trygve Haavelmo. The card's own language, quoted as system copy rather than biography: You pressure-test an idea in public and let the better one win.

Trygve Haavelmo in the public record

He received the Nobel Memorial Prize in Economic Sciences in 1989. After attending Oslo Cathedral School, Haavelmo received a degree in economics from the University of Oslo in 1930 and eventually joined the Institute of Economics with the recommendation of Ragnar Frisch. Haavelmo was Frisch's assistant for a period of time until he was appointed as head of computations for the institute. In 1936, Haavelmo studied statistics at University College London while he subsequently traveled to Berlin, Geneva, and Oxford for additional studies. Haavelmo assumed a lecturing position at the University of Aarhus in 1938 for one year and then in the subsequent year was offered an academic scholarship to travel abroad and study in the United States. During World War II he worked with Nortraship in the Statistical Department in New York City. He received his PhD in 1946 from Oslo University for his work on The Probability Approach in Econometrics which he had completed while at Harvard in 1941. He was a professor of economics and statistics at the University of Oslo between 1948–79 and was the trade department head of division from 1947 to 1948.

Where the record meets the 5 of Clubs

A card is a calendar coordinate, not a cause. What follows sets one line of the card's own published language beside one sentence of the sourced record, paired by a documented rule. It is a resemblance offered for the reader to weigh — not a claim about Trygve Haavelmo, and not a forecast of a Nobel Prize.

Also on the record

1. In 1989, Haavelmo was awarded the Nobel Prize in Economics "for his clarification of the probability theory foundations of econometrics and his analyses of simultaneous economic structures." Haavelmo resided at Østerås in Bærum.
2. He died on 28 July 1999 in Oslo.
3. Judea Pearl wrote "Haavelmo was the first to recognize the capacity of economic models to guide policies" and "presented a mathematical procedure that takes an arbitrary model and produces quantitative answers to policy questions".
4. According to Pearl, "Haavelmo's paper, 'The Statistical Implications of a System of Simultaneous Equations', marks a pivotal turning point, not in the statistical implications of econometric models, as historians typically presume, but in their causal counterparts." Haavelmo's idea that an economic model depicts a series of hypothetical experiments and that policies can be simulated by modifying equations in the model became the basis of all currently used formalisms of econometric causal inference." (The biostatistics and epidemiology literature on causal inference draws from different sources.) It was first operationalized by Robert H.

FAQ

What is Trygve Haavelmo's birth card?

The 5 of Clubs. December 13 maps to that card through the public Card Blueprints formula. The year of birth is not used.

Does a birth card predict a Nobel Prize?

No. These pages are coordinates, not fortune-telling. A birth card names a calendar day in a 52-card year. It does not forecast prizes, character, or fate.

Where do Trygve Haavelmo's dates come from?

Birth date 1911-12-13 is the Nobel Prize API v2.1 day-precision date, verified against Wikidata P569 (CC0, day precision, Gregorian preferred). The two sources match. Year-only Nobel dates and Nobel↔Wikidata conflicts are dropped, not guessed. Page hooks and evidence come from the Wikipedia REST summary (CC BY-SA 4.0).
