Behaviour under imperfect competition on markets for agricultural goods in economically less developed countries, exemplified with the rubber value chain

拟议项目的重点是在需求方不完全竞争的情况下分析市场进程。将从理论上模拟不同规模的经济行为主体的行为，然后以印度尼西亚詹比省和世界的天然橡胶价值链为例进行实证检验。不同的规模包括在宏观一级高度集中的国际贸易（对橡胶国际贸易流动的“按市场定价”分析），印度尼西亚詹比省橡胶加工业在中间一级的动态（分析工厂定价策略的“广义最大熵”方法），在微观层面，小贸易商/中间商与詹比省工厂互动的多样性（以需求方市场力量为特征的价值链多层次博弈理论模型）。

The focus of the proposed project is the analysis of market processes in the context of imperfect competition on the demand side. The behaviour of economic agents at various scales will be modelled theoretically, and then tested empirically using the example of the value chain of natural rubber in the Indonesian province Jambi and the world. The different scales include at the macro level the highly concentrated international trade ('Pricing To Market' analysis of international trade flows of rubber), at the meso level the dynamics within the rubber processing industry in the Indonesian province of Jambi ('generalized maximum entropy' approach for analysing the pricing strategies of factories), and at the micro level the diversity of the interactions of small traders/middlemen with factories in the province of Jambi (game theoretical modelling of multiple levels in value chains characterised by demand side market power).
