Structural vs Atheoretical Econometrics

Forthcoming in the Journal of Econometrics, by Michael Keane:
In this paper I attempt to lay out the sources of conflict between the so-called “structural” and “experimentalist” camps in econometrics. Critics of the structural approach often assert that it produces results that rely on too many assumptions to be credible, and that the experimentalist approach provides an alternative that relies on fewer assumptions. Here, I argue that this is a false dichotomy. All econometric work relies heavily on a priori assumptions. The main difference between structural and experimental (or “atheoretic”) approaches is not in the number of assumptions but the extent to which they are made explicit.
If I can return to this after finals week, I will try and add some comments regarding the content. For now, I just suggest that it is worth a read and some thought.

am i allowed to take a automobile insurance business to small claims court? The insurance supplier rejected my claim, (I would go ahead and take responsible driver to small claims nevertheless I've got no address to serve them or send a demand letter). And the second driver was at fault however his insurance provider states there may be a difference in this claims so that they have to take the word of their insured vs. my word. I do think they acted in undesirable belief and did not perform a proper investigation would this be a valid claim in small claims court? I must take the at fault drivers insurance provider (not my own) to small claims for the damages to my car.
