Explain the concept of the long-run in economics and how it differs from the short-run.
The long-run in economics is a theoretical concept where all markets are in equilibrium, and all prices and quantities have fully adjusted. It contrasts with the short-run, where there are constraints and markets are not fully in equilibrium. In microeconomics, the long-run has no fixed factors of production and allows for adjustment of output level by changing the capital stock or by entering or leaving an industry. In macroeconomics, the long-run is the period when the general price level, contractual wage rates, and expectations fully adjust to the state of the economy, in contrast to the short-run when these variables may not fully adjust.
What did Alfred Marshall's work Principles of Economics contribute to the differentiation between long-run and short-run economic models?
What did Alfred Marshall's work Principles of Economics contribute to the differentiation between long-run and short-run economic models?
Alfred Marshall's work Principles of Economics, published in 1890, introduced the differentiation between long-run and short-run economic models. His introduction of long-run and short-run economics reflected the ‘long-period method’ that was a common analysis used by classical political economists.
How did the differentiation between long-run and short-run economic models come into practice in economics?

Study Notes
The Concept of Long-Run and Short-Run in Economics
- In economics, the long-run and short-run are two distinct timeframes used to analyze economic phenomena.
- The long-run refers to a period of time in which all factors of production can be varied, and all inputs can be adjusted to optimal levels.
- In contrast, the short-run is a period of time in which at least one factor of production is fixed, and only some inputs can be adjusted.
Alfred Marshall's Contribution
- Alfred Marshall's work, Principles of Economics, contributed significantly to the differentiation between long-run and short-run economic models.
- Marshall's work introduced the concept of the long-run and short-run as a way to distinguish between the two different timeframes of economic analysis.
Development of Long-Run and Short-Run Models
- The differentiation between long-run and short-run economic models emerged in the late 19th and early 20th centuries as economists sought to understand the dynamics of economic systems.
- The development of these models allowed economists to analyze and understand the behavior of economic systems over different time periods.
Characteristics of the Long-Run in Microeconomics
- In microeconomics, the long-run is characterized by perfect competition, where firms have no market power, and there are no barriers to entry or exit.
- In the long-run, firms can adjust their production levels and input mixes to minimize costs and maximize profits.
- The long-run is often used to analyze the behavior of firms and industries in the absence of external shocks or changes.
Definition of Long-Run and Short-Run in Economics

- The short-run is a period of time in which at least one factor of production is fixed, and only some inputs can be adjusted.

Description
Test your knowledge of the theoretical concept of the long-run in economics, where all markets are in equilibrium, and compare it to the short-run with some constraints and markets not fully in equilibrium. Explore the absence of fixed factors of production in the long-run and the freedom to adjust output levels.
