Inelastic supply: An economic approach to simple interval schedules

Area of Science:

• Behavioral Economics
• Animal Behavior Studies
• Operant Conditioning

Background:

• Economic theory posits an inverse relationship between commodity supply and market price.
• This principle has been explored in various contexts, but less so in animal behavior models.
• Understanding these relationships can offer insights into decision-making and resource allocation.

Purpose of the Study:

• To experimentally test the economic theory's prediction of an inverse relationship between supply and price.
• To investigate if this economic principle applies to behavioral responses in pigeons.
• To analyze the impact of varying reinforcement quantities on behavioral cost.

Main Methods:

• Three experiments were conducted using pigeons responding on variable-interval schedules.
• Quantity of reinforcement was manipulated by varying reinforcement rate and magnitude across experiments.
• Behavioral cost, measured as responses per reinforcer, was recorded.

Main Results:

• A consistent inverse relationship was observed: as the quantity of reinforcement supplied decreased, behavioral cost increased.
• These findings align with predictions from economic theory.
• The response rate-reinforcement rate function was bitonic in most subjects, supporting economic and regulatory theories over traditional reinforcement theories.

Conclusions:

• The study provides empirical support for economic theory in a non-human animal model.
• Behavioral cost in pigeons adjusts inversely to the quantity of reinforcement supplied.
• Results challenge traditional reinforcement theories and support economic and regulatory frameworks for understanding behavior.
