My conclusion is that if you find a godfather there is no doubt you can publish this (Godfather will give you status, reference and fit the paper to the general framing in the field).
Of course, the most difficult thing would be to publish it without godfather. This seems difficult: when all the papers and research are fuzzy in a lot of aspects, how is going someone to decide if your results is pure speculation or well-grounded logic? When there is hardly a strong standard for publishing it seems very difficult to know the answer in advance.
I would say that your present status in the university would allow the paper to peer-review it. You would need to choose the journal with the help of someone around and then look for the references. Success will not be guaranteed...
So I will say the best way is to find a godfather to write the article with. It would be the easiest path. Find someone who is known as trustworthy and good person, he does not need to be a crack. Better if he is not....
Of curse, this is you have time and desire... but it was fun to look for it.. I doubt someone used before the thermodynamic instabilities to analize the dislocation int he economy wiht a model as simple as the one you are considered.
By the way I am still surprised that the idea that consumers make rational choices is accepted. Research has shown with literally thousand of studies that there is no such a thing as rational choice... but this is another topic...
A pleasure I therefore claim to show, not how men think in myths, but how myths operate in men's minds without their being aware of the fact. Levi-Strauss, Claude
