    Description: An interesting puzzle in business practices is that although many researchers emphasize the benefits of a revenuesharing contract, a wholesale contract has remained to be the most common contractual form. By introducing the concept of unobservable efforts, we examine the contractual efficiency of a wholesale contract and a revenue-sharing contract. The multi-task agency model and experimental design approach are used to analyze the relationship between the contractual efficiency and parameters. A major finding of our study is that a wholesale contract coordinates unobservable efforts, while it fails to coordinate the order quantity decision. Because unobservable efforts have mixed effects on the contractual efficiency, the superiority of contract type depends on parameters. This finding implies that a wholesale contract can be a competitive contract, especially when unobservable efforts are heavily involved. Our conclusion is that the current popularity of a wholesale contract...

    Description: Firms need to find a proper fit between their own information technology (IT) capabilities and IT systems in order to enhance performance. Thus, the purpose of this paper is to examine the moderating effect of certain e-procurement system types on the relationship between IT capabilities and firm performance. Moderated regression analysis is used to test for interaction effects of IT capabilities, including collaboration capability and dynamic capability, and e-procurement system types including, E-market and Extranet. Data of 142 Korean manufacturing firms are collected and used in the analysis. There is a stronger effect when relationships between IT capability and firm performance are considered with the involvement of other resource such as e-procurement system type. When e-procurement has a minimum-information sharing function and a high market-making function, collaboration capability had a greater contribution on financial performance. On the other hand, when an e-procurement...

    Description: Though sustainability exists as major objective of pursuing innovation, the effect of it on innovation performance is still unanswered. While the outcome of innovation should consider both input and output, moreover, studies on sustainable innovation are yet to consider the overall efficiency, but rather the performance itself. To fill the gap between the effect of sustainability as the objective of innovation and its innovation performance, and to bridge the hole between the outcome of sustainable innovation and its efficiency, we analyze the relationship between sustainability as innovation objective and innovation efficiency. We use 441 manufacturing companies in Korea from 2016 KIS data, and perform the data envelopment analysis (DEA) method to calculate efficiency score of each firm and tobit regression analysis to investigate the effect of sustainability as an objective of innovation on innovation efficiency. The results show that the objective of 'environmental improvement'...

    Description: This study investigates the impact of three institutional pressures, namely government, customer, and competitor pressures, on the environmental and operational performance of firms. These three institutional pressures are examined by implementing green supply chain management, considering the role of top management and studying social capital between buyers and suppliers in the supply chain. Data were collected through an electronic mail survey from buyer firms in the manufacturing industry in Korea. With 241 complete and usable responses, we used structural equation modeling to test our hypotheses. Our findings revealed that the majority of our hypotheses were supported, which is in line with the existing literature. However, the impact of coercive pressure on top management support and the impact of structural social capital on performance were found to be insignificant. The major contribution of our study is that it broadens the framework of green supply chain management (GSCM) by integrating major and recent constructs in the GSCM theory, while also providing instructive managerial implications through empirical evidence.

The efficiency of different methods is verified through simulation for 27 cases. Analysis of the results reveals that the efficiency of row classification of an airplane increases as the number of airplane seats increases in the case of identical numbers of passengers and travel time of baggage. When a passenger arrives before his or her baggage, classifying the baggage into business class and economy class has the highest efficiency increase. Finally, the method of classifying the baggage into each row has the highest efficiency increase when baggage arrives before its owner.

    Description: Byline: Jae Yong Shin,Jeong-Hoon Hyun, Seungbin Oh, Hongsuk Yang Keywords: Corporate Governance; Chaebol; Korea; Politically Connected Outside Directors (PCODs) Abstract Manuscript Type Empirical Research Question/Issue While most prior studies on the value of political connections focus on the political connections of controlling shareholders and top management, we examine the performance impact of appointing politically connected outside directors (PCODs) in Korean chaebol firms. Research Findings/Insights Using a manually collected sample of PCODs in Korean chaebol firms, we find that larger, high-performing, less volatile firms with a larger board and higher divergence between voting rights and cash flow rights are more likely to appoint PCODs in the next year. We also report that firms with a high number of PCODs exhibit better operating performance and enjoy lower risk. On the other hand, we find evidence of weak monitoring ability by PCODs. Overall, we suggest that the number of PCODs correlates positively with firm performance, and that the value effect of PCODs increases with the importance of internal trade among group affiliates, the existence of inside directorship by controlling shareholders, and potential settlements from pending litigation. We further differentiate between PCODs and find that former government officials as PCODs drive our findings. Theoretical/Academic Implications This study contributes to corporate governance knowledge by revealing the relationship between PCODs and firm performance via an empirical inquiry into the role of PCODs on the board. As the controlling shareholders of Korean chaebol firms obtain greater private benefits of control, and such firms may face active government involvement in curbing controlling shareholders' rent extraction, we examine the role and effects of PCODs in these situations and find evidence of the PCOD's value-enhancing effect. We also complement and extend prior studies by providing more direct mechanisms through which PCODs can add value above and beyond firms' ownership structure. Additionally, we expand the concept of political connection by analyzing outside directors' human and social capital from the resource dependence theory perspective. Our attempt complements prior research's exclusive focus on connections of large shareholders or top executives to political parties and is more comprehensive in illustrating the firm's dynamic business environment. Practitioner/Policy Implications The results of our study are potentially useful to regulators, who will benefit from an understanding of how the presence of PCODs on boards affects firm performance. In particular, our results suggest that in countries where recent reforms aim to improve minority investor protection and market confidence, regulators should consider the composition of outside directors as well as explicit board independence. The results of our study may also be useful to investors, financial analysts, and auditors, as they highlight the importance of considering specific features of board composition when assessing firms' future operating performance and risk mechanisms.

    Description: Information and communication technology (ICT) has emerged as a significant basis for improving the supply chain. Reports are, however, often conflicting about its effects on firm performance. In order to better assess the contribution of ICT on firm performance from the supply chain management perspective, we propose a research model to investigate the interaction effects of ICT and supply chain capabilities on firm performance. We test the research model with regression analysis on field survey data. The results indicate significant moderating effects of ICT characteristics on the relationship between supply chain capabilities and firms' market performance, but observed are only weak moderating effects on the relationship between supply chain capabilities and firms' financial performance.

    Description: "Reduction of material and energy consumption,, (RMEC) exists as a major objective of innovation and it is proved to affect positively to innovation performance from previous literature. Though innovation should be measured in efficiency rather than performance itself, however, the relationship between material and energy reduction on innovation efficiency is still unanswered. In this paper, we analyzed the effect of RMEC on innovation efficiency considering both innovation inputs and outputs. We utilized data of 388 manufacturing enterprises in Korea, and performed data envelopment analysis (DEA) and tobit regression analysis. According to the result, firms show difference by industry type in terms of innovation efficiency and RMEC. Moreover, the effect of RMEC on innovation efficiency turned out to be negative. The result indicates a possibility that input used for innovation might overweigh the output yielded when firms pursue innovation for the RMEC.
