Talk:Gravity model of trade

message: I added a sentence on other uses of the model, but really think that the whole article should be about the (economic) gravity model in general and not just the gravity model of trade. Nowadays the model is so frequently used for all kinds of bilateral data that the field of trade should not claim it as its own. And I don't see how trade has such a special way of using it that it justifies an extra wiki. Could we maybe make a special subsection for how trade GMs are different from others (i.e. probably talking about MRT)? Asdir (talk) 09:17, 15 September 2015 (UTC)
thread_title:  Other uses of the gravity model 

message: The article nowhere states what the \beta_k are. Are they universal constants that are the same for all trade systems? Are they fit constants to be estimated for each situation individually? Or are they specific to the situation, but can be calculated? Also, what are the (typical) values of those? About 1? About 2? About a million? --93.134.52.31 (talk) 07:44, 8 September 2015 (UTC)

replies: text: The above link is broken, but now see . It does not appear to be suitable as the starting text for a Wikipedia article, but perhaps some of the concepts covered would be helpful for editors here. -- Beland (talk) 23:25, 17 March 2023 (UTC)

message: It would be better to do more showing and less telling, or at least some showing of 1.) what kinds of metrics are typically used, and 2.) how empirical measurements compare to theoretical predictions. -- Beland (talk) 23:26, 17 March 2023 (UTC)
