The concept of production efficiency has been studied since the 1960s, but consumption activity as well may be inefficient for various reasons, such as product complexity, lack of information, the bounded rationality of the consumer and imperfect markets, to name a few. This study proposes a...

Amidst the overall trend of convergence in information technology, device convergence is noteworthy. This study looks at the possible direction of device convergence based on consumer preferences for the main attributes of the mobile terminal of the future. Conjoint analysis and a mixed logit...

Shadow price is one of the most important pieces of information in environmental decision making. Two different approaches—namely, economic and engineering—have been applied to obtain the shadow price of undesirable outputs, while using different methodological backgrounds and perspectives....

This paper investigates interindustry knowledge spillovers using input-output (IO) data and patent information, since spillovers can arise from different types of sources and linkages. Economic transactions of intermediate goods are used to track embodied knowledge flows with the data derived...

In this study we propose a mathematical definition of the consumption efficiency of multi-attribute products in the price–quality space. A new model, the discrete Range Adjusted Measure (RAM) model, is suggested as an empirical tool to measure the level of consumption efficiency. We further...

This paper examines the development pattern of the DEA (Data Envelopment Analysis) research field using Social Network Analysis. Nine stylized facts are verified: it is shown that the distribution of research performance is highly skewed, satisfying a power law, and that collaborative research...
