This paper uses various Data Envelopment Analysis (SBM-DEA) approaches to study the efficiency of major airlines in Asia-Pacific region. To evaluate the operation efficiency of fourteen major airlines in Asia-Pacific region from 2003-2011, Available Seat Kilometers(ASK), Available Ton Kilometers(ATK), the number of employees are used as input factors, Revenue Passenger Kilometers(RPK), Revenue Ton Kilometers(RTK), the amount of Sales are used as output factors.

The non-radial SBM-DEA (Slacks-based Measure of Efficiency) model was able to provide a more comprehensive efficiency of combining economic performance and regional difference. And it was also able to capture slack values in input excess and output shortage.

The results demonstrate that Korea and Japan airlines are operated efficiently and could be regarded as the benchmarking airlines. On the other hand, most of the China and ASEAN airlines are deemed to be inefficient. Also analyzing slacks may be more suitable way for the evaluation or suggestion of an improvement scheme for the inefficient airlines. The excess of labor is the major cause of the airlines’ inefficiency.

This paper investigates consumer perceptions of brand authenticity (BA), perceived value (PV) and brand trust (BT) into the context of craft beer market. The purpose of this paper is to examine the statistical associations between these constructs as well as the three antecedents of BA: individuality, consistency and continuity.

The survey, delivered in an online format, was completed by 749 respondents from the USA. These respondents were gained through a basic simple random sampling technique. After conducting data analysis techniques such as reliability, correlation and regression, all five research hypotheses were accepted.

All three antecedents of BA were found to have significant influence on the first-order construct. Also, BA was shown to have a substantial effect on both PV and BT. The relationship between brand individuality and BA was the most significant of the five, while the association between BA and PV was found to be the least significant.

Prior research on BA, the majority of which has involved a qualitative approach, has been severely limited. The authors’ work deepens the study of the effects of BA, or its various antecedents, on PV and BT, enhancing the research with an empirical, quantitative analysis. In addition to the shortage of investigation related to these factors, there has been a nearly complete absence of the application of these variables to the craft beer market.
