    Abstract: To improve patients' welfare, governments can regulate the availability of the low‐price drugs (LPDs) through lower wholesale purchasing or retail selling of the LPD. This paper characterizes two common constrained policies from the practices of pharmaceutical markets. The first (policy P) controls the ratios of the LPD's purchasing quantity and fee. The second (policy S) controls the ratios of the LPD's selling quantity and revenue. Considering a pharmaceutical supply chain consisting of two independent manufacturers and a hospital, we investigate the impacts of two policies on the LPD's availability and the whole industry gains. Our results show that policy P dominates policy S in two aspects: (a) policy P provides a higher product availability of the LPD and (b) policy P reduces less profits for the pharmaceutical supply chain. Specifically, policy P could incur a win‐win outcome for the patient and the supply chain. We further show that the demand allocation of the LPD, the substitution degree, and the profit margins' difference can significantly affect the performances of the policies.

    Abstract: In order to increase the structural performance of rotary tillage knife, a badger claw toe was selected as the bionic prototype of the rotary tillage knife, and the bionic optimization design of the rotary tillage knife was carried out. The structural similarity between the badger’s claw toe and the rotary tiller is 0.7073 by the fuzzy algorithm, and the shape goodness of fit between the final mole’s claw toe and the digging shovel is 0.9556 by MATLAB. Using 3D modeling software NX10.0, we established a three-dimensional model of the rotary tillage knife. Furthermore, we use Workbench to carry out static analysis on the three rotary tillage knives and obtain their stress and deformation. Similarly, we also obtain their vibration frequency through modal analysis, summarize, and compare the experimental data. The outcomes indicate that compared with the ordinary rotary tillage knife, the strain and stress of the bionic rotary tillage knife with sawtooth tangent blade arrangement are reduced by 5.20% and 2.84%, respectively. Moreover, the specific strength and specific stiffness are increased by 3.99% and 6.49%, respectively. The structural efficiency is improved by 11.36%. However, the stress of the bionic rotary tiller with full serration is reduced by 7.38%. We also observed that the specific strength and specific stiffness were improved by 11.97% and 2.37%, correspondingly. Overall, structural efficiency has increased by 14.64%. The rotary tiller has also attained noble optimization outcomes in terms of stability, strength, and stiffness.

    Switching to profitable outside options under supplier encroachment

    Abstract: In practice, manufacturers may encroach on retail markets through a variety of methods, one being through the use of an online channel direct to the consumers, called encroachment. Current research typically assumes that downstream retailers retain procurement from the encroaching supplier. In reality, however, retailers may have the option of switching suppliers after encroachment. By considering a supply chain consisting of one manufacturer and one retailer with outside options, this paper analyzes the effects of the option of switching suppliers on the supply chain players' strategic interactions under the threat of supplier encroachment. We consider that the manufacturer makes encroachment decision preceding the retailer's switch decision. We capture various outcomes of the encroachment and switch decisions by using a classic encroachment model with quantity decisions (Cournot model). Specifically, we identify two effects of the outside option on the strategic encroachment decision. The first, the deterrence effect, means that the manufacturer's encroachment is deterred by the threat of switching supplies altogether; while the second, the permissive effect, indicates that the retailer intends to switch to the alternative source after the encroachment. Interestingly, we show that the encroachment could improve the total profit of the incumbent manufacturer and the retailer even when the retailer's switch has occurred. In this case, however, the manufacturer profits while the retailer is hurt by the encroachment and the switch. Finally, we also investigate several extended cases to demonstrate the robustness of our findings.

    Abstract: Two-stage network data envelopment analysis (DEA) is widely used to evaluate efficiency of different organizations with multiple operations processes or hierarchical structures. Although existing two-stage network DEA assumes two-stage systems resolve the inherent conflicts between two stages, the coordination effect between the two stages is usually ignored. Recently, the relation of two-stage network DEA to traditional “black box” DEA has been studied from the perspective of system coordination. A coordination efficiency was defined and measured by a DEA-based approach based on simple two-stage network systems. In this paper, we propose an extended DEA-based approach for measuring the coordination efficiency for general two-stage network systems. The paper shows that the coordination efficiency based on the multiplier DEA and envelopment DEA approaches is equivalent to each other under both constant returns to scale (CRS) and variable returns to scale (VRS) assumptions. The proposed approach is verified via two numerical examples finally.

    Abstract: More recently, the Chinese Government had been making appreciable efforts to stimulate and encourage entrepreneurial emission reductions. These efforts could be boosted by availability of dual asymmetric information about the adopted technology for efficient reduction and enterprises’ investment strategies, possibly leading to adverse selection and moral hazard. This paper incorporates Stackelberg game model and incentive mechanism theory to find a feasible solution to dual asymmetric information problem. Hence firstly, through application of linear function of the total emission, an emission reduction contract would be formulated for regulating incentive payments from government to supervisory authorities followed by derivation of a two stage principal-agent monitoring model based on the enterprise’s private information and action respectively. Some findings have been obtained through analysis of the monitoring models along with their comparison with the results of no monitoring scenario which confirm the effectiveness of hiring the supervisory authorities for monitoring of enterprises’ emission reduction, which, ultimately, would facilitate increasing payoff and efficient emission reduction. In this perspective, the action-based monitoring mechanism depicts overall government dominance. Several, managerial insights have also been provided for various scenarios and propositions and all the findings are illustrated numerically. It could prove highly beneficial and significant to the government in encouraging entrepreneurial emission reductions.
