Figure 1. — Categorization of economic agents: flow polarity and flow share. (a,b) Distributions of flow polarity and flow share in the cattle and swine markets. Flow polarity and flow share of an economic agent quantify its position along the supply chain and market leadership, respectively. Qualitatively, flow polarity (2.1) can be used to define suppliers, wholesalers and demanders, categories of agents corresponding to values that are negative, symmetrically distributed about zero, and positive, respectively. Similarly, flow share (2.2) can be used to define nichers (low values), followers (mid values) and leaders (high values). (c,d) Distributions of flow polarity and flow share per group of agents in the cattle and swine markets. Groups are either sets of French farms or trading agents, or a single entity aggregating all agents located outside of France, namely the rest of the world. Flow polarity and flow share are calculated over year 2009 for cattle and throughout year 2010 for swine.
