Understanding Costs in the Short Run

The video tutorial explains the concepts of average, marginal, and total costs in the short run. It describes the shapes of total fixed cost, total variable cost, and total cost curves, emphasizing the influence of the law of diminishing marginal returns. The total fixed cost curve is constant, while the total variable cost curve initially shows increasing returns due to productivity gains, followed by diminishing returns. The total cost curve combines fixed and variable costs, mirroring the shape of the variable cost curve but at a higher level.

What are the three types of cost curves discussed in the short run?

• Total fixed cost, total variable cost, and total cost

• Average cost, marginal cost, and total cost

• Fixed cost, variable cost, and marginal cost

• Total cost, average cost, and marginal cost

How do total fixed costs behave over a range of output?

• They decrease with output

• They increase with output

• They remain constant

• They fluctuate randomly

What influences the shape of the total variable cost curve?

• Law of increasing returns

• Law of diminishing marginal returns

• Law of constant returns

• Law of decreasing returns

What happens to productivity when more workers are added initially?

• Productivity fluctuates

• Productivity remains constant

• Productivity decreases

• Productivity increases

What is the result of over-utilization of capital in production?

• Decreased costs

• Diminishing returns

• Constant productivity

• Increased productivity

How is the total cost curve related to the total variable cost curve?

• It is higher than the total variable cost curve

• It is unrelated to the total variable cost curve

• It is lower than the total variable cost curve

• It is identical to the total variable cost curve

Where does the total cost curve start on the graph?

• At the average cost point

• At zero output

• At the total fixed cost point

• At the total variable cost point

What does the vertical distance between the total cost and total variable cost curves represent?

• Total cost

• Total variable cost

• Marginal cost

• Total fixed cost

What is the equation for total cost?

• Total cost = Total fixed cost + Total variable cost

• Total cost = Average cost + Marginal cost

• Total cost = Total cost + Marginal cost

• Total cost = Fixed cost + Variable cost

Why does the total cost curve follow the shape of the total variable cost curve?

• Because total fixed cost is variable

• Because total cost is independent

• Because total fixed cost is constant

• Because total variable cost is constant
