From the Financial Times, a snippet from a guest post by Wang Zhenying, director-general of the research and statistics department at the PBoC’s Shanghai head office and vice chairman of the Shanghai Financial Studies Association, summarising the arguments in his new Chinese-language textbook on economics.
“Trading economics” is one new theory emerging against this backdrop. Mainstream economics deduces the macro whole by extrapolating from the behavior of individual “representative agents”. Trading economics replaces this with a systematic and comprehensive analysis approach. It stresses that in an interconnected world, the interaction between trading subjects is the fundamental driving force behind the operation, development, and evolution of economic systems.
Trading economics first analyses the actions of trading subjects, then builds a dynamic trading network among trading subjects through trading relations, and finally reveals the operational rules of the economic system. The rules could be examined from two perspectives: short-term and long-term. The business cycle and price changes are examined in the short-term perspective. The long-term perspective would focus on the rules of economic evolution as well as changes in technology, knowledge, system, and network.
Throughout the history of economics, trading economics is the first and foremost theory to incorporate all economic phenomena into an all-encompassing logical system. It changes the long-standing scenario in the economics field, that is, the macro was separated from the micro, and the short-term from the long-term. Trading economics is a revolution of mainstream economic theories and is bound to exert a great and profound impact on all areas, including economic theoretical research and practical application.
NB: I thoroughly enjoyed reading this summary and expect to contextualize future research with some of the theoretical frameworks as presented here.
