Suppose that the market for candy canes operates under conditions of perfect competition, that it is initially in long-run equilibrium, and that the price of each candy cane is $0.20. Now suppose that the price of sugar falls, decreasing the marginal and average total costs of producing candy canes by $0.15. Based on the information given, we can conclude that in the short run a typical producer of candy canes will be making:

negative economic profits.
positive economic profit.
The answer is impossible to determine based on the information given.
