This study discusses a DEA approach for environmental assessment. The proposed approach examines a level of simultaneous achievement on economic prosperity and environmental protection, so measuring the level of 'sustainability.' DEA, standing for Data Envelopment Analysis, has been widely...

This study proposes a use of data envelopment analysis (DEA) to assess the performance of energy industries. The DEA is a nonparametric approach that does not assume any functional form for performance assessment. The purpose of this study is to discuss how DEA can examine the current energy...

We introduce managerial delegation into Pal's (1998) model and examine the impact of the introduction of managerial delegation on endogenous timing in a mixed duopolistic model for differentiated goods. We show that a public firm and a private firm choose quantities sequentially in the...

This paper investigates productivity improving merger activities between a public firm and a private firm in mixed oligopoly. We assume that the merged firm has two plants (formerly, firms). We show that both owners of a public firm and a private firm want to merge by coordinating their...

Environmental assessment and pollution protection are important concerns in modern business and policy. Consumers are interested in corporate efforts on not only their products but also environmental protections and pollution preventions. To attain a high level of sustainability (i.e., economic...

The purpose of this research is to evaluate the impact of vertical unbundling on German electric utilities. Our research mainly relies on in-depth interviews with sector-experts from the German utilities. We will discuss both short-term changes and the long-term impact on competition in the...
