Theoretical Justification.
The gravity equation has long been an institutionalized topic of research in economics and there has been
a great deal of studies on the gravity model itself.
▸ The properties of econometric estimations and methodologies make the gravity theory an interesting
topic of research and inquiry.
▸ The developments of the gravity model can be discussed systematically in several developmental phases:
