The Law of Supply states that, other factors remaining constant, there is a direct relationship between the price of a commodity and its quantity supplied. As the price of a good increases, the quantity supplied by producers increases, and as the price decreases, the quantity supplied decreases. This positive correlation exists because higher prices offer greater profit potential, incentivizing producers to increase output.

The law operates under the following assumptions:

• The prices of factors of production (land, labor, capital) remain constant.
• The state of technology remains unchanged.
• The goals of the firm (e.g., profit maximization) do not change.
• There are no changes in government policies like taxes or subsidies.
• The prices of related goods remain constant.
• Producers expect no future changes in the price of the commodity.

Demand forecasting methods are essential for production planning and inventory management. Two prominent methods are:

• Test Marketing Method: In this approach, a firm selects a sample market or a specific geographic area to launch a product on a trial basis. By observing actual consumer behavior, purchase patterns, and feedback in this controlled environment, the firm estimates the potential demand for the product on a larger scale. It is highly reliable as it relies on actual market data rather than hypothetical responses.
• Expert Opinion Method: This is a qualitative technique where the firm consults industry experts, sales representatives, or consultants who possess deep knowledge of market trends and consumer behavior. These experts provide subjective estimates based on their experience and intuition. A popular variation is the Delphi Method, which involves multiple rounds of anonymous surveys to reach a consensus among experts, helping to mitigate individual biases.
