Answer Details
The sufficient condition for a firm to be in equilibrium is that the marginal cost curve cuts the marginal revenue curve from below. Let me explain why in a simple and understandable way.
In economics, equilibrium refers to a state where there is no tendency for change or adjustment. For a firm to be in equilibrium, it means that it has achieved a balance between its costs and revenues, and there is no incentive or need for it to make any changes in its production or pricing decisions.
To understand this condition, let's consider the relationship between marginal cost (MC) and marginal revenue (MR). Marginal cost represents the additional cost incurred by the firm to produce one additional unit of output, while marginal revenue represents the additional revenue earned from selling one additional unit of output.
When a firm is in equilibrium, it means that it has found the optimal level of production where its costs and revenues are balanced. At this point, the firm has no incentive to produce more or less because any deviation would result in lower profits.
The condition for equilibrium is that the marginal cost curve cuts the marginal revenue curve from below. In other words, the marginal cost of producing one additional unit is less than or equal to the marginal revenue earned from selling that unit.
If the marginal cost is higher than the marginal revenue, it would mean that the firm is incurring higher costs to produce an additional unit than the revenue generated from selling that unit. In this case, the firm would be better off reducing its production level to avoid losses and move towards equilibrium.
Conversely, if the marginal cost is lower than the marginal revenue, it implies that the firm is generating more revenue from selling an additional unit than the cost of producing it. In this situation, the firm would benefit from increasing its production level to maximize profits and move towards equilibrium.
By having the marginal cost curve cut the marginal revenue curve from below, the firm ensures that it is operating at the optimal level of production where its costs and revenues are balanced. This condition indicates that the firm has reached a state of equilibrium and has no incentive to make any adjustments in its production or pricing decisions.
It is important to note that while profitability is a desirable outcome for a firm, it is not the sole criterion for determining equilibrium. A firm can be profitable but still not in equilibrium if its marginal cost is not in line with the marginal revenue.
In summary, the sufficient condition for a firm to be in equilibrium is that the marginal cost curve cuts the marginal revenue curve from below. This condition ensures a balance between costs and revenues and signifies that the firm has reached an optimal level of production without any incentive for further adjustments.
