张五常

张五常 is the economist at the center of 【旧番重听】蜜蜂经济学’s empirical turn. The source describes his investigation of U.S. beekeepers and growers after hearing that farmers used contracts to rent hives for pollination.

In the episode, Zhang’s value is methodological as much as theoretical. He checks a famous James Meade example against industry practice and finds that pollination and honey access can be priced through crop-specific, seasonal, and location-specific agreements. That makes him the source’s main figure for Externality Internalization, Pollination Service Market, and a non-financial extension of Market Efficiency.
