â â â â â â â â â â â â  abstract: â  as a result of recent developments, global economic centre of gravity has slide to asia-pacific region. it is predicted that asia-pacific countries will take place at the first row in global trade and nearly a half of the total trade will intensify in this region at the year 2030. on the other hand, the region covers countries from different levels of devel...

In this letter we work out the secular precession of the spin of a gyroscope in geodesic motion around a central mass in the framework of the Dvali-Gabadadze-Porrati multidimensional gravity model. Such an effect, which depends on the mass of the central body and on the orbit radius of the gyroscope, contrary to the precessions of the orbital elements of the orbit of a test body, is far too sma...

This article has considered the volume and direction of Iran’s trade using the gravity model. The major issue in this analysis is to explore why Iran over or under-traded with the 76 countries relative to the predicted trade flows of the model. The study attempts to explore the reasons from the respect of both the model itself and Iran’s trade structure. This is done by analysing the performanc...

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...

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...

abstract t his paper explains bilateral trade patterns between south korea and thirteen opec member countries over the period 1980-2014 using a gravity model. the estimation results show that the gravity equation fits the data reasonably well. we confirmed the existence of long term relationships between the bilateral trade flows and the main components of gravity model - gdp, income (gdp per c...

one of the most remarkable basis of the gravity data inversion is the recognition of sharp boundaries between an ore body and its host rocks during the interpretation step. therefore, in this work, it is attempted to develop an inversion approach to determine a 3d density distribution that produces a given gravity anomaly. the subsurface model consists of a 3d rectangular prisms of known sizes ...
