Using Trading Streams of 80 Countries for estimation of Bilateral Export and Import functions Via the Gravity Model and the explanation variables of the Exporter and Importer

Gravity model

The results showed that population growth increases the ability to produce more for domestic consumption, and as a result, imports were reduced; besides gap variable is an important barrier for trade.

Investigating the AFTA agreement formation based on bilateral trade flows between members

Gravity model

The results of this estimate indicate that integration has increased the AFTA trade

Effects of Uruguay-Argentina and Uruguay-Brazil Bilateral

Trade Agreements using Gravity Model

Gravity model

The results of this estimate indicate that the trade potential estimated by the model for Uruguay trade with Argentina and Brazil is significantly different from reality. And this is due to the similar manufacturing structure of these countries. In fact, these three countries cannot cover exchange needs of each other, and as a result, other countries have more business-oriented relationships than their own trade relationship.

The estimates show Bangladesh trade is not independent of the behavior of business partners (such as the exchange rates determination and the tariffs)

A Study of the Factors Affecting Iran’s Export

Gravity model

The results of the estimated models showed that Iran’s export could be explained by the significant portion of factors included in the gravity model. Furthermore, the results are different with respect to geography and their level of development of business partners
