Microeconomics STC=TC?

The Chinese meaning of each letter abbreviation in microeconomics is as follows: P: price Q: quantity D: demand S: supply E: equilibrium (or expectation). E: Elasticity ed: Demand Price Elasticity es: Supply Price Elasticity exy: Demand Cross Price Elasticity U: Utility TU: Total Utility MU: Marginal Utility CS: Consumer Surplus MRS: Marginal Substitution Rate L: Labor K: Capital TP: Total Output AP: Average Output MP: Marginal Product MRTS: Marginal Substitution Rate C: Cost STC: Short-term Total Cost TFC: Total Variable Cost. This AFC: average will not become this AVC: average variable cost AC: average total cost MC: marginal cost LTC: long-term total cost LAC: long-term average cost SAC: short-term average cost LMC: long-term marginal cost SMC: short-term marginal cost TR: total income AR: average income MR: marginal income PS: producer surplus MP: marginal product VMP: marginal product value W: labor price MRP: marginal income product MFC: marginal factor cost R.

TC stands for total cost and q stands for quantity.

Total cost TC is the sum of total fixed cost (TFC) and total variable cost (TVC). Therefore, the total cost curve is above the total variable cost curve, and the vertical distance between the two curves is equal to the total fixed cost.

The characteristics of the total cost curve depend entirely on the characteristics of the total variable cost curve. Therefore, with the increase of output, the total cost curve first decreases and then increases.

It is found that effective cost analysis is the basic factor for enterprises to succeed in the fierce market competition. Imperfect cost analysis will lead to simple cost reduction, which will make the enterprise lose its vitality.

Establishing a scientific and reasonable cost analysis and control system will enable enterprise managers to clearly grasp the cost structure, profitability and the correct direction of decision-making, become the key support for internal decision-making, and fundamentally improve the cost situation of enterprises.

Platinum Consulting believes that correct cost analysis plays a very important role in whether a company is profitable. Due to the disadvantage of cost analysis, enterprises may make pricing mistakes because they don't allocate the expenses to different products reasonably, thus falling into the strange circle of multi-sales thanks for a long time.
