This paper presents an overview of recent development in the new economic geography (NEG), and discusses possible directions of its future development. Since there already exist several surveys on this topic, we focus on the selected features of the NEG which are important yet have attracted...

Since the inauguration of the Greater Mekong Sub-region (GMS) Economic Cooperation Program in 1992, road infrastructure projects have played a very important role. Their economic significance, especially, has become a focal point after the introduction of the concept of the three economic...

With regression formulas replaced by equilibrium conditions, a spatial CGE model can substantially reduce data requirements. Detailed regional analyses are thus possible in countries where only limited regional statistics are available. While regional price differentials play important roles in...

By analyzing a comprehensive dataset on transport transactions in Japan, we describe a directional imbalance in freight rates by transport mode and examine its potential sources, such as economies of density and directionally imbalanced transport flow. There are certain numbers of observed links...

This paper presents a framework for an SCGE model that is compatible with the Armington assumption and explicitly considers transport activities. In the model, the trade coefficient takes the form of a potential function,and the equilibrium market price becomes similar to the price index of...

This paper examines the conventional assumption that bilateral transport costs are symmetric. We develop an economic geography model with transport sector in which asymmetric freight rates can occur as a result of density economies. Comparing this to models without density economies, we show...

This paper investigates Japanese trade by mode of transport, i.e., air transport versus maritime shipping. Some facts about Japanese machinery exports by mode of transport in the 1990s are examined first. Then it will be shown that products of the machinery sector where international...
