An agent-based approach is a numerical (computer-intensive) method to explore the complex characteristics and dynamics of microeconomics. Using the agent-based approach, this study investigates the learning speed of traders and their strategic collaboration in a dynamic market change of...

This study examines how consumers select ecologically efficient water heaters in Japan. Energy conservation in household water heating is increasingly important for reducing an amount of CO2 emission, because the share of water heating in household energy consumption is approximately 30%....

This study discusses a new DEA (Data Envelopment Analysis) approach to measure the unified (operational and environmental) efficiency of energy firms. It is widely known that they produce not only desirable (good) outputs (e.g., electricity) but also undesirable (bad) outputs (e.g., CO2) as a...

This study examines the performance of MAIS (Multi-Agent Intelligent Simulator) equipped with various learning capabilities. In addition to the learning capabilities, the proposed MAIS incorporates collaboration among agents. The proposed MAIS is applied to estimate a dynamic change of wholesale...

Environmental assessment recently becomes a very large-scale policy issue among corporate leaders, environmental researchers and individuals who are interested in environmental protection in the world. This study discusses how to apply Data Environment Analysis (DEA) for environmental...

This study investigates a linkage among environmental, operational and financial performance in Japanese manufacturing industry. All manufacturing firms examined in this study are listed in Tokyo stock exchange market. We use DEA (Data Envelopment Analysis) as an evaluation methodology. This...

Environmental assessment is increasingly important in preventing various types of pollutions. Data Envelopment Analysis (DEA) has been long used as an operational performance measure, but we have insufficiently explored the use of DEA for environmental assessment. This study explores a new use...

Over a career extending back to the late 1930s Professor William W. Cooper has published books and articles in the field of accounting, mathematics, operations research, management science, engineering, economics, public policy and the behavioural sciences, reflecting wide interdisciplinary...

This study examines whether agglomeration economies, market access and public fiscal transfer have a positive or negative influence on the productive efficiency of Japanese regional industries. To attain the research objective, stochastic frontier analysis is applied to a Japanese data set at a...

This study examines the cost structure of Japanese electric power industry to investigate whether a structural reform on the industry really enhances a cost-saving benefit to consumers. A composite cost function model, using a panel data set, is used for this study. The data set consists of nine...
