Tirage court
Le court terme n’est pas défini par un calendrier fixe, mais par la condition dans laquelle au moins un intrant du processus de production reste fixe.…
Le court terme ne fait pas nécessairement référence à une durée spécifique, mais plutôt à une période au cours de laquelle au moins un des intrants est supposé être constant en quantité. En règle générale, le capital, comme les machines, reste constant, tandis que la main-d’œuvre est flexible et peut être ajustée.
À court terme, les entreprises peuvent augmenter ou diminuer leur production en modifiant la quantité de l’intrant variable, qui est la main-d’œuvre. Cela reflète la capacité de l'entreprise à réagir aux conditions du marché dans le cadre de certaines contraintes.
Par exemple, une entreprise de construction automobile peut augmenter sa production en embauchant plus de travailleurs ou la diminuer en utilisant une main-d’œuvre plus petite. Cependant, le fabricant doit maintenir constants les intrants en capital, tels que les machines et la taille de l’usine, car leur modification nécessite beaucoup de temps.
Il est utile de comprendre le court terme, en particulier lorsque les entreprises font des plans pour une période au cours de laquelle une entrée doit rester constante.
Par exemple, lorsque le constructeur automobile planifie la production pour le mois à venir, il peut ajuster la main-d’œuvre, mais doit travailler dans les limites de son capital existant.

Q1: What does the short run mean in economics?
The short run refers to a production period where at least one input remains constant in quantity, not a specific timeframe. Typically, capital like machinery and plant size stay fixed, while labor can be adjusted. This constraint allows firms to respond to market changes by hiring or reducing workers while maintaining existing productive capacity.
Q2: Why is labor considered a variable input in the short run?
Labor is a variable input because its quantity can be readily adjusted to increase or decrease production without significant time or cost. Unlike capital, which requires substantial investment and time to change, firms can quickly hire or lay off workers to respond to demand fluctuations and optimize output within their fixed capacity constraints.
Q3: How does a firm adjust production in the short run?
Firms adjust short-run production by changing the quantity of variable inputs, primarily labor. For example, a car manufacturer can increase output by hiring more workers or decrease it by reducing workforce size. The firm operates within its fixed capital constraints, such as existing machinery and plant size, which cannot be quickly modified.
Q4: What is the difference between fixed and variable inputs?
Fixed inputs, typically capital like machinery and facilities, cannot be easily or quickly changed during the short run. Variable inputs, such as labor, can be readily adjusted to modify production levels. This distinction defines the short run: when at least one input is fixed, the firm operates under capacity constraints that shape its production decisions.
Q5: How does understanding the short run help business planning?
Understanding the short run helps firms plan production when certain inputs must remain constant. For instance, a manufacturer planning monthly production can adjust labor but must work within existing capital constraints. This framework enables realistic forecasting and decision-making about output levels given the firm's immediate capacity limitations and input flexibility.
Q6: What happens when all inputs can be changed in production?
When all inputs can be changed, the timeframe becomes the long run rather than the short run. In the long run, firms can modify both capital and labor, eliminating the capacity constraints that define short-run production. This flexibility allows firms to achieve optimal input combinations and scale operations according to long-term strategic objectives.
Q7: Can you provide an example of fixed and variable inputs?
Consider a lemonade stand: the stand itself is the fixed input representing physical capacity, while the number of workers is the variable input. Production, measured in glasses of lemonade, can be increased by employing more workers or decreased by reducing staff. The stand's size constrains maximum output, but labor adjustments allow production flexibility within that constraint.
