What Factors Affect the Establishment of Voluntary Fisheries Management? The Case of Pooling Systems in the Management of Sakhalin Surf Clams by Japanese Fishery Cooperatives
発表者：東田 啓作氏（関西学院大学）
【概要】
Focusing on ‘pooling systems’ in the management of Sakhalin surf clams, this paper examines what factors influence the enforcement of voluntary resource management. We interviewed more than 50 cooperatives from August 2006 through October 2010, and collected data that cannot be obtained by using Fisheries Census. Using the bivariate probit analysis to the choice problem of pooling systems, we find that the number of fishers who engage in surf clams fishing, the length of the coast of the area for a cooperative, and the fishing efficiency significantly affect the introduction of pooling systems. Interestingly, a non-linear relationship between the dependent variable and the number of fishers is clearly observed: small-size and large-size cooperatives are likely to have pooling systems, whereas medium-size cooperatives tend not to have those systems.

Relationship Specificity, Market Thickness and International Trade
発表者：荒 知宏氏（福島大学）
【概要】
How does a firm distribution affect gains from trade? To address this question, we develop a dynamic industry model in which relationship specificity endogenously determines the thickness of markets. In a closed economy, a sector with higher relationship specificity becomes a thicker market and attains a higher ratio of matched firms to unmatched firms. When the economy is allowed to trade, the thickness of markets varies in response to matching possibilities among firms in a global economy, indicating that resource allocations induced by trade liberalization cannot be fully understood without an endogenous distribution of firms.

On the Stability of Intra-industry Trade
発表者：大久保 敏弘氏（慶應義塾大学）
【概要】
This paper studies the over-time stability of two-way trade (i.e. intra-industry trade) in product-country pairs in OECD countries. We find that product-country pairs are fairly difficult to sustain intra-industry trade over time and many products frequently switch among two-way, one-way and zero trade over time. Two-way trade is rather unstable. Our estimation results suggest that two-way trade with different market size and long distance is likely to be unstable. In addition primary products are more unstable than manufacturing products.

原産地規則の適合費用と国際複占競争の均衡
発表者：溝口 佳宏氏（帝京大学）
【概要】
本稿では，自由貿易協定における原産地規則が寡占競争的な市場の均衡に与える影響を３国モデルで分析する．域内と域外に１社ずつ立地する企業が域内国市場でクールノー競争を行い，原産地規則を満たして域内国市場へ非関税で供給するためにかかる適合費用が域内企業よりも域外企業のほうが高いとき，適合費用と域内輸入国が課す域外関税の相対的な水準により，２社とも原産地規則を満たすか，域内企業のみが原産地規則を満たすか，または２社とも原産地規則を満たさない，という３つの均衡が存在する．そのうち，２社とも原産地規則を満たす場合に，適合費用の差が２社間で十分大きいとき，原産地規則の厳格化が域内企業の利潤を増加させうることを示す．

Why Do We Need the Movement of Natural Persons Agreement?: A Possible Conclusion of FTAs Fueled by MNP
発表者：小森谷 徳純氏（中央大学）
【概要】
Using an international oligopoly model, we explore the effects of reductions of trade cost (non-tariff barrier) and travel cost on the home and foreign economies in the presence of endogenous choice of FDI production level. In the case where the home firm produces in both countries, while the consumers always gain from the cost reductions, the effects on the producers are very complex. Using the findings, we discuss the importance of agreement on movement of natural persons (MNP) and show possibilities of FTA conclusion supported by MNP agreement.

Effects of emissions taxes under imperfectly competitive markets: A case of integrated market
発表者：黒田 知宏氏（名古屋学院大学）
【概要】
This paper investigates emissions taxes from the viewpoint of emission reduction in imperfectly competitive integrated markets. Using a simple monopoly model, we show that the effectiveness of emissions taxes is restricted by source of the emissions (production or consumption), market integration and the spillover effects. We rst show that emissions taxes are not very effective to protect environment when emis-sions are generated by consumption because of the spillover effects stemming from the shape of the demand functions. Other policies such as production taxes and consumption taxes are compared with emissions taxes. Production taxes are more effective than emissions taxes. Shape of the cost function does not play a key role in the integrated markets because the spillover effects mainly stem from the shape of the demand functions under the integrated markets.

How to Commit to a Future Price
発表者：服部 圭介氏（大阪経済大学）
【概要】
A monopolist selling durable goods and also consumables that require use of the durable goods faces a commitment problem: each consumer expects the firm to charge a monopoly price for consumables, leading a consumer to have a low willingness to pay for the durable good. The paper considers three credible mechanisms which would induce the firm to charge a low price for the consumables: paying a financial firm to subsidize production of consumables, allowing entry into the consumable market, and selling the durable good to consumers who little value the consumables.
