from the perspective of new growth models and new international trade theories, both exports and imports play an important role in a dynamic economy. economically, we cannot merely emphasize on a positive trade balance and we ignore the benefits of imports, and also we cannot advise negative trade balance. but the main concern of policy makers about international trade should be making stabilit...

We explore the consequences of placing the Standard Model gauge fields in the bulk of the recently proposed localized gravity model of Randall and Sundrum. We find that the Kaluza Klein excitations of these fields are necessarily strongly coupled and we demonstrate that current precision electroweak data constrain the lowest states to lie above ' 23 TeV. Taking the weak scale to be ∼ 1 TeV, the...

A new gravity model with the function F (R) = (1/β) arctan (βR− βR) instead of the Ricci scalar in the Einstein–Hilbert action, describing inflation of the Universe, is suggested and analyzed. We obtain constant curvature solutions of the model in the Jordan frame. Performing the conformal transformation of the metric, the potential and the mass of a scalar degree of freedom in the Einstein fra...

Trade among Arab countries has been very weak despite previous efforts to engage into different forms of regional economic integration. Using the flexible framework provided by the Gravity Model, the paper gives an order of magnitude of the main factors often presented in explaining the weakness of inter-Arab Trade. The results of the model together with several indicators about export profiles...

This paper uses a static and dynamic gravity model of trade to investigate the link between German development aid and exports from Germany to the recipient countries. The findings indicate that in the long run German aid is associated with an increase in exports of goods that is larger than the aid flow, with a point estimate of 140 percent of the aid given. In addition, the evolution of the e...
