CORE DEFINITION

Analyzes the impact of changes in factor endowments on output. It states that, with constant commodity prices, an increase in the endowment of a factor will lead to an increase in the output of the good that intensively uses that factor, and a decrease in the output of the other good.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Predicting the impact of factor changes. It provides an analytical tool for understanding how changes in factor endowments affect the industrial structure. In analyses of demographic changes or capital accumulation, it helps predict which industries will expand and which will contract.

Anchor fast decisions

With relative commodity prices fixed, an increase in the supply of a factor leads to an increase in the output of the good that uses that factor intensively and a decrease in the output of the other good.

Sherlocking

Sherlocking refers to the phenomenon where a platform owner copies the features of a third-party developer's app and integrates them into the platform, thereby rendering the third-party app obsolete. The term originates from Apple's Sherlock search tool, which was introduced in Mac OS 8.5 and later incorporated features similar to those of third-party search utilities like Watson, leading to the coining of the term.

Beat Frequency

The term "beat note" or "beat frequency" originates from acoustics, referring to the interference of two sound waves with similar but different frequencies. The resulting interference signal has a frequency equal to the absolute difference between the two original frequencies, hence the name. This concept is also applied in optics and electronics, where combining two signals of different frequencies yields a new signal with a frequency equal to their difference. For example, consider two sine waves with equal amplitude, no phase difference, but slightly different frequencies.
