How large are the gains from trade? Do all trade models have the ‘same old gains’? Arkolakis, Costinot, and Rodriguez-Clare (2012) show that many quantitative trade models that summarize trade responses via a single elasticity have the same welfare implications. I develop a flexible approach to estimating trade responses using a translog expenditure function, and find welfare results that diffe...

Unstable factors such as international relations, geopolitics, and transportation routes make natural gas trade complex changeable. Diversified flexible sources of liquefied (LNG) can guarantee the energy supply security gas-consuming countries. Therefore, it is very important to find potential links help government partners prepare strategically in advance. In this paper, global LNG network ta...

Frank D. Graham (1890–1949) presented an innovative multi-country, multi-commodity trade model that attached great importance to link commodities and quantity adjustments, not perfect specializations price adjustments as emphasized by John Stuart Mill Alfred Marshall. However, due some shortcomings, this was sufficiently understood has been forgotten. This study reconstructs Graham’s theory of ...

We propose a new link metric called normalized advance (NADV) for geographic routing in multihop wireless networks. NADV selects neighbors with the optimal trade-off between proximity and link cost. Coupled with the local next hop decision in geographic routing, NADV enables an adaptive and efficient cost-aware routing strategy. Depending on the objective or message priority, applications can u...

the link between international conflict and economy linkage is one of the focal subjects in international political economy (ipe). the aim of this article is to scrutinise the impact of the economic factor on managing indo-pakistan conflict based on ipe approaches. so, the article organizes as follows: first, it is tried to provide a brief coherent theoretical framework concentrated on conflict...

We design network topologies and routing strategies which optimize several measures simultaneously: low cost, small routing diameter , bounded degree and low congestion. This set of design issues is broader than traditional network design and hence, our work is useful and relevant to a set of traditional and emerging design problems. Surprisingly, a simple idea from the research on small-world ...
