keresletbl

Keresletbl is a hypothetical economic construct used in teaching and speculative modeling to describe a component of demand that remains relatively stable despite short-term price fluctuations. It is intended to capture how necessity, habit, contractual obligations, and long-term expectations can sustain a baseline level of purchases in a market. The term appears to derive from the Hungarian word kereslet, meaning demand, with a suffix that gives it a formal label in model notation. It is not an established concept in mainstream economics but is used in some pedagogical materials to illustrate the separation of non-price determinants from price-responsive demand.

Keresletbl represents a floor value of demand, D_base, that persists under a defined price band. It operates alongside the elastic component of demand, which responds to price changes. Factors that expand kereszletbl include essential goods, default contracts, and informational inertia.

In a simple model, total demand D(p) = kereszletbl + ΔD(p), where kereszletbl ≥ 0. ΔD(p) captures price-elastic response and is typically a decreasing function of price. In dynamic simulations, kereszletbl is estimated from historical data during price shocks or from survey-based measures of necessity.

Recognizing kereszletbl helps explain why some markets show resilient demand despite price spikes, influencing pricing strategy, inventory management, and policy design. Critics note that defining a fixed floor can be sensitive to time horizon and data quality.
