INTRODUCTION

English translation pending.

CORE DEFINITION

The Linder hypothesis holds that the more similar two countries' per-capita income levels, the more similar their demand structures, and therefore the larger their trade with each other, chiefly in manufactured goods. Poor and rich countries often cannot do business at all, because their demands are not on the same wavelength. Beyond trade, it advises looking for similarity rather than complementarity in partners and customers: the easiest deals are with people at your own stage, facing your own problems.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Similarity scan: rank prospects by shared stage and shared problems rather than by what they lack. - Channel check: test whether your message actually matches the prospect's level of need. - Complement trap: stop pursuing pairs that look complementary but share no taste.

Anchor fast decisions

Income level shapes the basket of goods people demand, so countries at the same level develop overlapping markets and trade intensively, while distant income levels produce disjoint demand and little to exchange, even where formal comparative advantage exists.

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.
