The impact of quantity-based cost decline on supplier encroachment

Abstract: We study a supply chain in which a supplier with encroachment capability and quantity-based cost decline sells through a retailer with demand information advantage. By solving a signaling game, we find that cost decline increases the possibility of order distortion. The obtained results also show that without encroachment, both supply chain members are better off from cost decline; with encroachment, cost decline always hurts the retailer and benefits the supplier only if the direct selling cost is not very high. In addition, encroachment benefits the supplier when the direct selling cost or the cost decline efficiency is relatively low, while benefits the retailer when the direct selling cost is sufficiently high. Finally, we discuss on different information structures and obtain some information management insights.

Effect of perceived justice on subcontractor willingness to cooperate: The mediating role of relationship value

Abstract: Cooperation between subcontractor and general contractor provides the foundation for the successful delivery of every construction project. As one of the most important factors influencing subcontractor behavioral intentions, the perceived justice from previous collaborative experience affects the willingness of a subcontractor to cooperate with a general contractor in the future. In this paper, a model is built based on social exchange theory to examine the relationship between justice perception, relationship value and subcontractor willingness to cooperate (WTC). Analysis of data from 122 subcontractors demonstrates that distributive justice and interactional justice positively affect WTC, and relationship value from the general contractor partially mediates such effects. However, procedural justice does not significantly affect WTC. The study provides a new perspective for examining the internal mechanisms between subcontractor justice perception and WTC. The findings will also help general contractors understand how their behaviors affect subcontractor WTC, thus providing practical implications for subcontracting management.

What determines academic entrepreneurship success? A social identity perspective

Abstract: Universities and institutes are increasingly recognized as important sources in national innovation systems. As such, an increasing number of academics are participating in entrepreneurial and other commercial activities, and the topic of academic entrepreneurship has attracted wide attention. This paper aims to explore the effect of entrepreneurial identification on academic entrepreneurship from the social identity theory viewpoint and consider the effects of context (social capital inertia, entrepreneurial narrative). On the basis of 248 academic entrepreneur samples, empirical results indicate that the relationship between entrepreneurial identification and academic entrepreneurship performance is positive. In addition, the abovementioned relationship is negatively moderated by social capital inertia while positively moderated by entrepreneurial narrative. Moreover, entrepreneurial identification is best for academic entrepreneurship performance in the context of low levels of social capital inertia and high levels of entrepreneurial narrative. Theoretical contributions, practical implications, limitation and future research are discussed.

Trading networks, abnormal motifs and stock manipulation

Abstract: We study trade-based manipulation of stock prices from the perspective of complex trading networks constructed by using detailed information of trades. A stock trading network consists of nodes and directed links, where every trader is a node and a link is formed from one trader to the other if the former sells shares to the latter. Specifically, three abnormal network motifs are investigated, which are found to be formed by a few traders, implying potential intention of price manipulation. We further investigate the dynamics of volatility, trading volume, average trade size and turnover around the transactions associated with the abnormal motifs for large, medium and small trades. It is found that these variables peak at the abnormal events and exhibit a power-law accumulation in the pre-event time period and a power-law relaxation in the post-event period. We also find that the cumulative excess returns are significantly positive after buyer-initiated suspicious trades and exhibit a mild price reversal ...
