Meh. The standard of "support" is pretty low. I spent a lot of time looking through the literature for empirical support for 1/ the Philips curve, and 2/ gravity models of trade. I looked for the first out of personal interest, and for the second because economists often claim that gravity models are well-supported.
Where empirical studies were actually available, they usually had large numbers of parameters, they did not test on diverse datasets (e.g. Philips curves across different economies), and they never considered an alternative hypothesis or simple baseline.
