Prekyb

Prekyb is a theoretical construct used in studies of market exchange and digital commerce. In this context, it denotes an integrated module that handles procurement, pricing, and distribution within a marketplace.

Origin and terminology: The name derives loosely from the Lithuanian word prekyba meaning commerce; in educational and simulation settings, resorting to 'prekyb' represents a minimal, stylized trade subsystem.

Model components: Participants include buyers, sellers, and platform intermediaries; flows include demand, supply, pricing, and inventory; mechanisms include price discovery, matching, and settlement; features include network effects and transaction costs.

Applications: Used in teaching, simulations, and hypothetical policy analysis to explore how changes in fees, transparency, or information asymmetry affect liquidity and welfare.

Limitations and interpretation: As a simplified model, prekyb abstracts away legal, regulatory, and logistical complexities; results depend on assumptions about agent behavior and market structure.
