This article presents a bibliographic review of the gravitational model in international trade from the time it was first associated with Newton's law of universal gravitation. Firstly, I will introduce the concept of gravity in commerce as originally intended by Isard (1954) in relation to...

Within the framework of location theories in economics, we propose a theoretical development of Walter Isard’s Gravity model of trade (1954). Through our extension of the model, we provide a better understanding of its main tenets, as commercial attraction, center of gravity in markets,...

This article is a theoretical development of the gravitational model through logical and mathematical method. Once again, I will try to see how this tool developed in physics may give new insights into the field of international trade. Therefore, this paper attempts to answer to the following...

Notwithstanding its importance in light of current migration patterns, the link between immigration and innovation is largely understudied and confined to investigations relying predominantly on US data. Thus, the present work will focus on this relation by considering the factors which...

This monography presents a bibliographic review of the gravitational model in sociophysics since its origins in Newton’s conception. Furthermore, a theoretical development of the gravitational model through the logical and mathematical method is illustrated. How this tool has developed in...

This article is a theoretical development of the gravitational model through an econophysical approach and physical tools. Once again, I will try to see how this model developed in physics may give new insights into the field of international trade. Therefore, this paper attempts to answer the...

This article presents a bibliographic review of the gravitational model in sociophysics since its origins in Newton’s conception. Considering the crucial role played by physics in expanding our understanding about social sciences, I will preserve such an approach throughout the article....
