The gravity equation should also work well at predicting trade within a country, or intra-national trade. Panel B of figure 6.9 graphs the value of exports and the gravity term between any two Canadian provinces. There is a strong positive relationship between the gravity term between two provinces and their trade. The best fit line gives a constant term of When gravity term is 1, the predicted amount of trade is  1.3 billion.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
