Background
The concept of the short run is integral in economic analysis because it helps to understand the temporal limitations faced by firms and other economic agents. During the short run, the flexibility with which firms can adjust their inputs is constrained, affecting decisions and outcomes.
Historical Context
The distinction between short run and long run was popularized by classical and neoclassical economists who were interested in the impact of different timescales on economic behavior. This modeled more realistic scenarios in which immediate and future production capacities could be distinctly analyzed. Key figures like Alfred Marshall helped introduce these concepts to widespread economic study.
Definitions and Concepts
- Short Run: In microeconomics, the short run is a period during which at least one factor of production remains fixed, imposing constraints on the ability of the firm to change its level of output. Examples often include fixed capital such as machinery and buildings, which cannot be altered immediately.
- Long Run and Medium Run: The short run contrasts with the medium and long run, periods in which more or all factors can be altered to optimize production.
Major Analytical Frameworks
Classical Economics
In classical economics, the short run helps differentiate between immediate phenomena and long-term outcomes. It often assumes that wages and prices do not adjust instantaneously, causing short-term divergences from long-term equilibrium.
Neoclassical Economics
Neoclassical models use the short run to examine situations where some inputs are fixed, facilitating the analysis of marginal costs and profit maximization under immediate constraints.
Keynesian Economics
Keynesians explore short-run economic fluctuations primarily in terms of demand-side factors. They emphasize short-run rigidities and discuss policies like fiscal stimulus as remedies for short-run economic problems.
Marxian Economics
Marxian approaches might observe the short run in the context of production cycles and the labor market. They may also correlate it with economic exploitation and capitalist dynamics that cause short-term economic changes.
Institutional Economics
Institutional economists consider short-run economic behavior influenced by ingrained norms and institutional limitations which could rigidify resource allocation and economic dynamics.
Behavioral Economics
Behavioral economists explore how decision-making in the short run may diverge from rational models due to biases and heuristics, providing insights into short-term planning errors or irrational choices.
Post-Keynesian Economics
In post-Keynesian economics, short-run constraints often emphasize financial and borrowing constraints and how these interact with production capabilities.
Austrian Economics
Austrian economists typically focus on entrepreneurial adaptation within the short run, analyzing how these adjustments set the stage for longer-term changes.
Development Economics
Development economists may study how short-run barriers affect long-term growth, highlighting constraints in resources like human capital and infrastructure that impede quicker developmental strides.
Monetarism
Monetarists consider the short-run impacts of changes in the money supply, looking at delays in the effect on prices and employment.
Comparative Analysis
Acknowledging the characteristics of the short run across different schools of thought helps in understanding diverse economic phenomena and policy implications. Comparing and contrasting these views offer a holistic understanding of economic behaviors and outcomes.

Related Terms with Definitions
- Long Run: A period in which all factors of production and costs are variable.
- Medium Run: An intermediate time horizon where some adjustments have been made but not all long-term changes are possible.
- Fixed Costs: Costs that do not vary with the level of output in the short run.
- Variable Costs: Costs that vary directly with the level of production.
