題目　　　"Altruism and the Transfer Paradox in an OLF Model (joint with Mitsuyoshi Yanagihara)"

要旨　　　This paper examines the transfer problem between two countries when both a donor and a recipient have the altruistic utility in a one-sector OLG model. We demonstrate that a strong form of the transfer paradox, in which the donor country is enriched and the recipient country is immiserized, never occurs. Any transfer cannot enrich a donor even if the donor is highly altruistic, whilst a transfer may immiserize a recipient if the recipient is highly altruistic. This result suggests that high altruism of the donor cannot explain the motivation to voluntarily make a transfer.

題目　　"The Cost Channel and Exchange Rate Systems"
要旨　　This paper investigates the role of the cost channel in the choice of exchange rate systems with a two-country model with financial intermediary. We compare macroeconomic stability and the properties of the international transmission of business cycles under three exchange rate systems, a flexible (FLEX), monetary union (MU) and a unilateral peg (PEG). When the firms finance limited parts of their operational costs from the commercial bank, or the cost channel is weak, macroeconomic volatility is highest under FLEX. This is because stabilization in the nominal exchange rate helps to stabilize other macro variables under MU and PEG. We assume the central bank in a monetary union follows a Taylor rule with inflation and output in both countries, thus, volatility becomes higher under PEG than MU. On the other hand, when the firms finance all their operational costs from the commercial bank, or the cost channel is strong, FLEX becomes the regime that realizes the lowest volatility. Responses in inflation and other variables to disturbances are amplified through the cost channel. Under FLEX, the central banks in each country controls the policy rates against the fluctuation in their own inflation and output. The choice of exchange rate system significantly depends on the existence of the cost channel.

題目　　　"Does Trade Liberalization Improve Public Firm's Productive Efficiency?"

要旨　　　This paper studies how a tariff reduction influences the productive efficiency of a public firm competing against a private firm, by focusing on the public firm's incentive to make cost-reducing R&D investment. It is shown that if a tariff reduction induces a foreign firm to enter into the domestic market wherein public monopoly prevails, the public firm's productive efficiency deteriorates dramatically. However, subsequent trade liberalization steadily improves the efficiency. Furthermore, it is also shown that efficiency under trade liberalization can be higher than that under public monopoly, depending on the curvature of the public firm's reaction curve and demand curve.

題目　　　"Probit-VARモデルの推定法の提案と為替介入への応用"
要旨　　　本論文ではProbit-VARモデルの推定法の提案を行う。Probit-VARモデルは二項選択(もしくは多項選択)モデルを利用したVARモデルである。既存のVARモデルでは質的変数を被説明変数にすることができなかったが、本論文ではその方法ついて論じている。このモデルの利点は質的データの時系列分析をすることが可能であり、本論文ではこのモデルを応用して為替介入の効果の分析を行っている。

題目　　"Special Economic Zones, Urban Unemployment and Environmental Protection (with and Muneyuki Saito)"
要旨　　We examine environmental and economic influences from the formation of special economic zone (SEZ) and stricter pollution control in the economy with urban unemployment of Harris-Todaro type. We suppose in our model that pollution is discharged from urban manufacturing and SEZ sectors, and the government sets the maximum allowable pollution level. We, then, show that, in contrast to Chaudhuri and Adhikari (1993), the formation of SEZ mitigates unemployment rate even if domestic capital can move between urban and rural sectors, and the price of pollution permits is lower than marginal environmental damage in the situation where the optimal level of pollution allowance is attained. Moreover, we confirm that an establishment of the SEZ may stiffen the optimal level of pollution allowance.

題目　　"International Trade and Optimal Management of Shared Renewable Resource (with Yasuhiro Takarada and Weijia Dong)"
要旨　　本論文では、国際的に共有される再生可能資源の管理と国際貿易について分析をしている。管理費用に見合う実行可能な管理方法として最も望ましいといわれているのは、産出管理である。産出管理とは、再生可能資源の産出量を直接規制するものである。河川の水や地下水などの取水制限、野生動物の捕獲頭数の制限、水産物の総漁獲量制限が代表的な例である。複数国で共有する資源の場合、1国だけでの資源管理は効果がほとんどないため、国際協調が資源管理には不可欠である。回遊性魚類のマグロなどの水産資源は、沿岸の関係国がそれぞれ漁獲可能量の上限を設定して資源を保護・管理している。近年の貿易自由化の進展で、資源の国際貿易は拡大の一途で、中でも資源管理が困難な国際的に共有される再生可能資源の減少が懸念されている。我々は国際貿易が各国の資源管理や資源水準、経済厚生に与える影響を2国2財一般均衡モデルで分析する。主な結果は以下の3点である。第一に、自給自足経済において、ある1国が一方的に資源管理を実施すると、相手国はそれにより利益を得る。また、資源管理がないオープンアクセスの状態から、一方的に僅かに資源管理を実施する場合は、相手国だけでなく資源管理の実施国も得をする。第二に、両国が資源管理を行っている下で貿易を開始すると、資源財の輸出国は定常状態で貿易利益を得るが、資源財の輸入国は定常状態で貿易損失を被る可能性がある。第三に、世界の経済厚生を最大化する最善の資源管理を実施したときの資源水準は、資源の自然回復力が最も高いMSY（最大持続生産量）を達成する資源水準よりも高いことが明らかとなった。

題目　　　"When Do Governments Mislead Home Consumers? (With Keisuke Hattori)"
要旨　　　This paper examines the incentive of the government to mislead home consumers, and investigates the effects of misinformation on the profit of the home producer, the home consumer surplus, and home and world welfare. We find that the government chooses the positive (resp. negative) amount of misinformation on the home (resp. foreign) product, which means that the government induces consumers to perceive the quality of the home (resp. foreign) product higher (resp. lower) than it truly is, although the positive (resp. negative) misinformation decreases (resp. increases) the consumer surplus. We also find that the government is likely to prefer to disparage the foreign product rather than to praise the home product when the consumption amounts are large, and when the difference between the price and the marginal cost is small. Moreover, we demonstrate that, the more liberalized the trade is, the stronger incentive the government has to mislead home consumers particularly by disparaging the foreign product.

題目　　　"International Integration with Heterogenous Immigration Policies (with Nicola Coniglio)"
要旨　　　Increasing economic integration between countries has been accompanied by a process of integration and harmonization of common and uniform rules in many policy areas. Immigration policies have been largely untouched by this process, in fact also in area of the world (such as the European Union) where a high degree of policy centralization and integration has taken place, countries still preserve full autonomy on deciding who, how many and under which conditions third-country individuals might cross their border in order to live and work. The aim of this paper is to investigate some of the welfare consequences associated to the existence of heterogeneous and uncoordinated immigration policy in an interconnected world. We build a simple three country model where two rich countries with different immigration policies form a federation and receive immigrants from a third developing country. We show the existence of strong immigration policy externalities; a more restrictive immigration policy in one country might reduce or increase welfare in the other country. In addition we consider the effects of economic integration within the federation in the form of free mobility of native workers. We show that labor market integration might lead to loose-loose situations in case of large displacement of immigration from the third country.

題目　　　"Wage Inequality and Human Capital Formation"
要旨　　　We investigate the effects of wage inequality between skilled and unskilled workers on human capital formation in a home country and their incentive for emigration when some of the workers in the home country can be accepted in a foreign country. Unlike the previous analyses on brain drain and brain gain, we pay attention to the fact that resources for human capital formation, such as education, are not necessarily supplied elastically and free. To take this fact into account, we include a resource market, i.e. the education market and consider transactions of education explicitly. We show that both skilled and unskilled workers in the home country always attempt to migrate even if they are less likely to be accepted in the foreign country. We also show that brain gain and brain drain take place simultaneously in the home country. In particular, if wage inequality is larger in the foreign country than in the home country, skilled workers in the home country experience brain gain, whereas unskilled workers in the home country experience brain drain. In contrast, if wage inequality is larger in the home country, skilled workers experience brain drain, whereas unskilled workers experience brain gain. Our results suggest that the effects of migration possibilities on human capital formation of different types of workers are affected by differences in wage inequality between the home and foreign countries and that the home country’s future wage inequality might be affected by the host country’s present wage inequality.
