This study explains about a phenomenon where the structure of the compensation plan for a single salesperson may vary as he/she gains experience. Unlike past studies that implicitly assume the limited effect on salesperson's experience, our result predicts that a salesperson will make an effort at every period early in his/her career without any commissions in order to gain experience. However, if one cannot expect any marginal returns of accumulated efforts, the sales manager must provide commissions on the high volume of sales at each period, to facilitate a high effort of a salesforce at earlier periods. Our paper provides important implications about dynamics in the compensation plan, which has not been addressed in the past studies but has frequently been witnessed in practice.

This paper deals with system thinking in the resilience of the SES (Social-Ecological Systems) around Mt. Gariwang, located in Jeongseon County, Gangwon Province, in particular with the disturbance that a new ski slope is planned to be built for the PyeongChang 2018 Winter Olympic. It first performs a literature survey and newspaper article search to summarize the controversy with regards to credible environmental and socio-economical impacts of the plan, and then elaborates a series of CLDs (Causal Loop Diagrams) to infer the dynamics of the impacts. The results imply that the natural restoration seems to be hard because the development activities can cause a great deal of damage to the ecosystem mainly due to soil degradation and the mitigation of icy valley effects with water exploitation for making artificial snow and so on. Moreover most of the households near the planned site seem to leave with land compensation, thus more policy efforts are needed to enhance the resilience of the ecosystem and the nearby society based on ecotourism.
