Our study employs an overlapping generations model in which the political powers of different generations（the working generation and retired generations with and without children）determine the distribution of fiscal burden among the generations. We investigate the relationship among the extent of intergenerational altruism, political regimes, and intergenerational distribution of fiscal burden. Our numerical simulations show that the more the working generation cares about the utility of the retired generation, the more likely it is for an intergenerational coalition to be established. This coalition can make the working generation better off by lowering their tax rates. We also show that Demeny voting, which allows parents to vote on behalf of their children, requires a higher degree of altruism to decide on intergenerational coalition. However, Demeny voting can make both the working generation and the retired generation with children better off once it establishes the intergenerational coalition.

In this paper, we formulate an econometric model that estimates both fiscal and tourism multipliers simultaneously for each remote island region in Japan, and analyze the results through a meta-analytic approach that allows us to evaluate the impact of this policy on regions with different characteristics. The results show that the null hypothesis that fiscal and tourism multipliers are zero in all remote island regions can be rejected. However, the null hypothesis that tourism multipliers are equal to zero in all remote island regions cannot be rejected for remote island regions with positive and statistically significant fiscal multipliers.

This paper evaluates the forecasting performance of econometric models and time series model in the context of predicting visitors’ inflow to Japan from some selected Western and Asian countries using annual data on visitors’ arrival to Japan from 1960─2009. The models considered include the static OLS, error correction model（ECM）, autoregressive distributed lag model（ADLM）, time varying parameter model（TVPM）and autoregressive integrated moving average model（ARIMA）. The aggregate forecasts for the two regions over all forecasting horizons clearly indicate that the time varying parameter model outperforms the other econometric models and the univariate time series model in the forecast competition. The superiority of the TVP model suggests that by taking into account the possibility of structural changes in model building, forecasts accuracy will significantly improve.

China accelerates banking system reforming as it features amongst the fastest-growing emerging economies in the world. This paper helps to detect the effects of reform by analyzing the cost efficiency of Chinese banks through using an unbalanced panel data of this growth taken from the years 2002 to 2009. We assess the bank cost efficiency of both absolute values and relative values by SFA. The results of SFA show that the cost efficiency ranks of both the bank individuals and the bank categories. The bank individuals with the highest relative cost efficiency are the China Development Bank（CDB）, a policy bank, and the Industrial Bank（IB）, a jointstock bank. The least cost efficient banks are the Agricultural Bank of China（ABC）, the China Bohai Bank （CBB）, and the Bank of China（BOC）, two of which are large state-owned commercial banks. Coinciding with previous research, the category of the state-owned commercial banks has the least cost efficiency across three sample groups. The most efficient category, however, is the policy bank group, which is a result that runs contrary to the bulk of literatures. Factor analysis panel regression results illustrate that total assets expansion, non-performing loans （NPLs）dispatching, and state ownership have significant effects on bank cost efficiency.

品質で差別化された製品に課される従量税と従価税が社会厚生に与える影響を比較分析するため，企業の品質選択行動を組み込んだ垂直的製品差別化モデルを構築し，品質を課税標準とした従量税の性質を分析する．Cremer and Thisse（1994）が分析した従価税との比較を行い，従量税は企業のコスト要因となるため価格競争を弱め品質を過剰にするが，消費者選好の異質性が高いときには従量税が望ましい場合があることを明らかにする．

本論文は，ある著作物（基本財）と，その著作物を利用することによって初めて価値を持つ付属財を想定し，独占的な小売企業のパッケージ割引提供行動を考察する．両財を必ず購入する消費者の率が，価格に応じて両財を購入するか否かを決定する消費者の数との比で，ある値を超える時かつその時のみ，小売業者はパッケージ割引を提供しないことによって利潤が高くなることを示す．また，最適パッケージ価格の比較静学分析も提示する．

本稿は，民間の介護サービス事業者への補助政策の財源として環境税を用い，この政策が経済に及ぼす影響について検討する．長期的にはこの政策の導入によって環境は改善し，資本ストックは減少する．また，それに伴い民間が供給する介護サービスの価格は低下し，そのサービスの質は改善する．さらに，汚染に伴う不効用への関心がある程度高い場合には，環境税導入政策によって，環境と厚生を同時に改善しうることが示される．本稿は，介護と環境分野において生じるいわゆる二重の配当を考察した．

本稿では，わが国の財政データを用いて，国と都道府県における歳入と歳出に関する因果性分析を行った．その結果，国レベルでは，歳入と歳出の間に長期・短期，名目・実質・GDP 比データを問わずinstitutional separation 仮説が支持された．一方，都道府県レベルでは，名目データについては短期的にfiscal synchronization 仮説が支持され，経済成長の影響を考慮したGDP 比データについては短期・長期ともにspend-tax 仮説が支持された．

研究開発や技術標準を促進するために，複数の特許保持者らが特許を持ち寄ることによって形成するパテントプールという特許の一括管理方式が利用される．多くのパテントプールが単一のパッケージライセンスを行う中で複数のパッケージライセンスを提示するパテントプールも観察される．本稿ではパテントプールのライセンス行動に注目し，パテントプールが複数のパッケージライセンスを提示する条件を考察する．
