electricity produced from magnetic coilIn the Dictionary of Theories, which contains an enumeration and 2 par explanation of 5000 different theories, I come across the question of how many theories in different fields have applicability to ours. The question makes one think that there are vast areas for formulating hypotheses and that many simple theories in one field are applicable in others. The almost exact relation between electricity and magnetism, and the many dualities in different fields leads one to search for general theories as well.

One of the most suggestive theories I came across in the dictionary was the Correspondence Theory. It says thats what true of the microscopic level is true of the macroscopic. I wish that were true. I studied the bid asked 50 years ago, and found many regularities. I have made a few augmentations at the microscopic level since then, but one wishes that they held up at the macro level.

One notes that when I found that closing prices tended inordinately to cluster at the round numbers in 1962 operation research, my thesis adviser at the flexionic university said I'd have a hard time getting it through the acceptance mill since it was really not economics. But now I note that almost half the articles in AER are of a market microculture level or expectations relating there to level.

Concerning your thesis, this is a good example of how the quantity of new theories and published papers is related to how much work is required and what tools are available. Studying market microstructure is so easy now compared to back in the day.
