all of these

The basic difference between the short run and the long run is that: all costs are fixed in the short run, but all costs are variable in the long run. the law of diminishing returns applies in the long run but not in the short run. at least one resource is fixed in the short run, while all resources are variable in the long run. economies of scale may be present in the short run but not in the long run.

at least one resource is fixed in the short run, while all resources are variable in the long run.

total fixed cost

Economies and diseconomies of scale explain: the profit-maximizing level of production. why the firm's long-run average total cost curve is U-shaped. why the firm's short-run marginal cost curve cuts the short-run average variable cost curve at its minimum point. the distinction between fixed and variable costs.
