This study analyzed core issues addressed in the tentative agreement of WTO ministerial meetings held to finish WTO/DDA negotiations in Geneva in July 2008. The objectives of this study are to analyze changes in tariff reduction on timber products, and their influence on demand and supply of the items according to the modality of Non-Agricultural Market Access (NAMA) and to provide basic information for strategy formulation of our country for further WTO/DDA negotiations. The results indicate that there will not be significant changes in the tariff on sawnwood and on veneer sheets, however, the tariff on plywood need to be cut by around 50% from the applicable tariff rates of 2008 on condition that our country is in the position of developed countries. Therefore, the item of plywood is expected to be influenced greatly according to the change in tariff reduction. From the analysis of influence of tariff reduction on the demand and supply of timber products including sawnwood and wood based panels, such as plywood, particleboard, and fiberboard, the import quantities of the items are expected to be changed from 0.8% to 13.3% if our country is in the position of developed countries, however, they are expected to decline by 0.8%~44.3%, if our country is in the position of developing countries (22, coefficient for developing members).

Applying Markov Stochastic Process theory, this paper attempts to suggest a tentative model explaining how private information may cause bargaining delay. It is shown that the bargaining delay is critically dependent on the specification of information. It turns out that the delay tends to be longer in bargaining where information is imperfect. This means that bargaining models frequently can have an infinite delay under imperfect information while they have finite delay of bargaining before reaching the agreements if information is perfect. Other interesting result is that bargaining delay may depend on who makes the offer first. And it is also shown that bargaining tends to end earlier if both players (seller and buyer) can make offers in turn than the case where only one side make a offer.

The construction of New Seoul International Airport is under way despite much controversy. Among much discussed, but not well-formulated controversy is the possibility of the airport as a hub in the North Asia Region. This paper specifies the factors which render it possible for an airport to be a regional hub. Then each factor is applied to the new airport to see whether it can function as a hub airport. Also examined is the qualitative cost and benefit calculation related to the hub function. The usual discussion has missed one big point of cost side of hub function in the belief that the hub only produces benefits to the national economy where the airline and airport industry belong; earlier-than-expected congestion and the necessity to expand the airport sufficiently enough to accommodate the increasing air demand. An airport as a hub is determined by several factors; geographical location ; economic status of the country where the airport belongs ; bilateral air service agreements according to which the airlines can exercise the route rights; the airport charges which directly influence the cost structure of the carriers ; international aviation and airport related policies of each country in the region ; airport capacity etc. The tentative implications of this paper are the followings; first, the new airport is able to function as a regional hub in the transpacific routes which connect Asian countries and North America. That is, directional hubbing by the airlines is implicated; second, the main benefits may be accrued to american airlines exercising all the route rights in the Asian region; third, the governmental effort to make the new airport a regional hub must take caution in optimizing the hubbing level (% of transitting passengers and freight) between the benefits and the costs. Further Studies may include optimal level of hubbing for the new airport and, quantification of the impact of the new airport on the national economy depending on the degree of hubbing.
