4. When talking about economics profits in a perfectly competitive market, the difference between the long run and the short run is that: in the short run firms can earn positive or negative economic profits, but in the long run firms have zero economic profits. 5. Assuming a firm’s costs are split between variable costs and fixed costs, once variable costs are covered,

if the price is equal to $6.
7. As a firm attempts to expand production, it must _____________ the wage it pays to attract additional help. This leads to ________ costs, making the long-run supply curve slope ___________.
increase; higher; upward.
8. The entry and exit of firms ensure that the ________________ is much more ________ in the long run than in the short run.
