Hicks’s thread (out of the equilibrium labyrinth)
揭示希克斯对经济主体的独特视角是其研究路径的基础，也是其市场、流动性、资本和风险理论的共同前提。该理论旨在处理不可测风险（即学习管理）的实际作用，并关注交易成本对学习诱导行为的价格和财富效应。
The work of John Hicks is an unending source of inspiration for many economists and an unsolved dilemma for historians of economic thought. This article highlights the fact that Hicks’s peculiar perspective on the economic agent constitutes the sub-structure underlying his research path, and the common premise to his theories of markets, liquidity, capital, and risk. Hicks’s theory of the agent was intended to address the factual role of non-measurable risk (i.e. learning management) and was primarily concerned with the price and wealth effects that the transaction costs (costs of learning and moving) entail for learning-induced behaviours.
