By building and solving numerical models of the parts supply problems (an example of the adverse selection problems), and analyzing various issues of the contract theory, we demonstrate the benefits of the numerical approach. First, this approach facilitates the understanding of the contract...

This is a study to develop and solve numerical models based on Itoh’s (2003, Ch. 1) “Parts Supply Problems” for better understanding the contract theory. In the first part of this paper, by following Itoh (2003) we investigate 2- and 3-agent type cases; in the succeeding part, by using...

We analyze the economic impact on key sectors of a compound disaster in Taiwan. While Taiwan has high-tech export-oriented industries such as semiconductors and electronic products, three out of four nuclear power plants are located in the at-risk areas close to its capital city with industrial...

We investigate a long-run impact of a compound disaster in northern Taiwan by describing a recovery process from the disaster with a dynamic computable general equilibrium model. After simulating losses of capital and labor in combination with a nuclear power shutdown, we conduct policy...

We used 1995-2000-2005 linked input-output (IO) tables for Japan to examine estimation errors of updated IO tables and the resulting prediction errors in computable general equilibrium (CGE) analysis developed with updated IO tables. As we usually have no true IO tables for the target year and...

National food security is one of the main justifications used to oppose agricultural trade liberalization in Japan. Opponents of agricultural trade liberalization argue that because food supply is subject to various uncertainties, importation of cheap foods is too risky a policy. We used a Monte...

The Great East Japan Earthquake and the subsequent tsunami hit and destroyed the Fukushima Daiichi Nuclear Power Station. People lost trust in the safety of nuclear power plants, and the regulatory authority became reluctant to permit power companies to restart their nuclear power plants. To...

After the Great East Japan Earthquake and the subsequent nuclear accident, nuclear power stations cannot be considered safe any longer and, thus, can be hardly allowed to restart in Japan. In this study, we develop a nine-region spatial equilibrium model for the Japanese power market and...

The Fukushima Daiichi Nuclear Power Station held by Tokyo Electric Power Company (TEPCO) had a serious nuclear accident in March of 2011. TEPCO's liability for the losses caused by this accident is speculated to reach several trillion yen. For this compensation, TEPCO is supposed to sell its...
