Abstract:
Market concentration among buyers of recycled materials is a phenomenon discussed since the 1980 s by the anti-trust literature. Yet, there is still a lack of studies on simultaneous market concentration on both the supply and demand sides. This is particularly relevant when Extended Producer Responsibility (EPR) policies produce two-sided waste generation and valorisation markets. Thus, the purpose of this study is to explore the link between market concentration on the generation side and market share on the valorisation side. Specifically, this research addresses the case of valorisation of commercial and industrial non-hazardous waste in Chile. The analysis covers 261 companies that valorised industrial and commercial non-hazardous waste between 2015 and 2019. Being part of the top 10 % of generator companies in Chile is significantly correlated to higher valorisation market share, in a context in which mean market share per company decreased, total tons valorised stagnated, and the country-level valorisation rate diminished.
摘要:
自1980年代以来,反托拉斯文献就讨论了再生材料购买者之间的市场集中现象。然而,仍然缺乏对供需双方同时集中市场的研究。当扩大生产者责任(EPR)政策产生双边废物产生和价值化市场时,这一点尤其重要。因此,这项研究的目的是探讨发电侧的市场集中度与估值侧的市场份额之间的联系。具体来说,这项研究针对智利商业和工业非危险废物价值化的案例。该分析涵盖了2015年至2019年期间对工业和商业非危险废物进行评估的261家公司。作为智利前10%发电机公司的一部分,与更高的价值市场份额显着相关,在每家公司平均市场份额下降的情况下,价值的总吨位停滞不前,国家一级的价格率下降。
