ESTIMATION OF PRODUCTION FUNCTION The principles of production theory discussed in Unit 7 are fundamental in understanding economics and provide an important conceptual framework for analysing managerial problems. In economics, a cost curve is a graph of the costs of production as a function of total quantity produced. Your teacher and professor will focus on the per-unit cost curves. A firm's short-run total cost (SRTC), average total cost (ATC), and marginal cost (MC) curves when total costs are a cubic and a quadratic function of output are shown respectively in panels (a) and (b) of Figure 1. In the short run, at least one input, such as capital, remains fixed, leading to the presence of fixed and variable costs. It helps businesses analyze and understand the cost structure, make informed decisions regarding resource allocation, pricing strategies, and profitability.
