Background
The concept of a queue is fundamental in both everyday life and economics. It refers to a line or sequence of people, vehicles, or other entities awaiting their turn to receive a good or service.
Historical Context
The study and formalization of queuing theory date back to the early 20th century with mathematical work initiated by Agner Krarup Erlang, primarily to address telecom traffic management. Over time, queuing theory has been extended to various fields including economics, operations research, and service management.
Definitions and Concepts
- Queue: A number of customers awaiting service.
- Queue Discipline: The rule or method governing the order in which customers in a queue are served. This can vary widely and include principles like first-come, first-served (FCFS), last-in, first-out (LIFO), random order, or some priority-based system.
- Queuing Models: These are theoretical models that simulate the behavior of queues to understand and optimize the process of queue management.
Major Analytical Frameworks
Classical Economics
Classical economic frameworks generally do not emphasize queue theory; however, scarcity, supply, and demand implicitly create situations where queues develop as a rationing mechanism.
Neoclassical Economics
Neoclassical economics also tends to focus on equilibrium and efficiency, with queuing arising in markets where supply cannot instantaneously adjust to demand.
Keynesian Economics
Keynesian models might involve queues in scenarios related to employment and resource allocation in aggregate demand contexts.
Marxian Economics
Queues may be interpreted as manifestations of scarcity and resource allocation under capitalism. Inefficiencies and inequities may be highlighted through the examination of who queues, for what, and for how long.
Institutional Economics
This framework examines the rules and norms governing queue disciplines and how different institutions manage and prioritize service.
Behavioral Economics
Behavioral economists may study how perceived fairness and patience (or impatience) influence how individuals interact with queues.
Post-Keynesian Economics
Queues can be important in this framework too, particularly in describing market constraints and efficiencies in response to aggregate demand.
Austrian Economics
Emphases might be placed on how queues form naturally and how they relate to market signaling and entrepreneurship.
Development Economics
Here queues might illustrate issues related to access to goods and services, particularly in developing economies where resources are limited.
Monetarism
Queques might be explored regarding liquidity and closed systems where resources must be controlled and doled out in an organized manner.
Comparative Analysis
By comparing these frameworks, one can see that, while the fundamental nature of queues remains the same, the interpretation and implications vary: from managing scarce resources to exploring human behavior in economic settings.

- Priority Queueing: A system where customers with higher priority are served ahead of those with lower priority.
- Random Order Queueing: No specific order in which individuals are served, it is entirely random.
- Simulation Models: Tools used in queuing theory to numerically predict and analyze queue behaviors.
