We study the process ee → ee at a high energy ee collider including the effect of graviton exchanges in the warped gravity model of Randall and Sundrum. Discovery limits for gravitons are established and the effects of polarization are discussed.

In this paper we calculate explicitly the secular classical precessions of the node Ω and the perigee ω of an Earth artificial satellite induced by the static, even zonal harmonics of the geopotential up to degree l = 20. Subsequently, their systematic errors induced by the mismodelling in the even zonal geopotential coefficients Jl are compared to the general relativistic secular gravitomagnet...

The paper analyzes the network structure of international trade. Adapting a network approach developed in the physical sciences, we propose that international trade functions like a scale-free network. For each commodity group we calculate a characteristic parameter which reflects the structure of its trading network. We then insert this variable into an expanded gravity model to explore the ef...

© A m Abstract: This paper investigates to what extent international migration can be explained by climatic variations. A gravity model of migration augmented with average temperature and precipitation in the country of origin is estimated using a panel data set of 142 sending countries for the period 1995 to 2006. We find two primary results. First, temperature is positively correlated with mi...

The ASEAN Free Trade Agreement (AFTA) was set up in 1993 and has already shown significant effects by 2010. This study empirically investigates the effect of trade creation on intra-ASEAN trade for the period of 1986 to 2010. Using the gravity model, we find that major determinants of bilateral trade in ASEAN are GDP, population, relative endowment, distance and common border. A dummy variable ...

Recently Ciufolini has suggested to use the perigee of the proposed LARES/WEBER-SAT satellite in order to measure the secular precession which would be induced on such Keplerian orbital element by a weak-field modification of gravity occurring in some Brane-World scenarios put forth by Dvali. This precession would amount to 0.04 milliarcseconds per year for LARES. In this paper we show that, ac...

We apply the gravity model to examine the effects of the Andean Community and Mercosur on both intra-regional and intra-industrial trade in the period 1980-1997. After accounting for size and distance effects, the Andean Community preferential trade agreements had a significant effect on both the differentiated and reference products, in particular capital intensive goods. In contrast, Mercosur...

Are trade blocs stumbling blocks or building blocks? This chapter reviews many political economy arguments. First come those that suggest that regionalism undermines support for more generalized liberalization. Then we consider arguments that say that regional initiatives help build political momentum for global liberalization. Arguments as to how the adoption of a regional trading area might p...

In 2010, Norway is still one of the richest countries in the world, with a GDP per capita corresponding to 56,140$ and an open economy able to move a large quantity of goods. After the Schengen agreement, the trade exchange between Norway and the rest of the European countries has largely increased. In this panorama, the Norwegian alcoholic market behaves under particular conditions. As it is w...

intra-industry trade (iit) comprises of instantaneous imports and exports of goods and services which are handled in a same industry. the importance of iit between trading partners refers to those tradable products that provide them with diversity and high technology. to expand its foreign trade relations, iran indeed requires such trade patterns that include diversification of goods and servic...
