Question

In the long run, a. inputs that were fixed in the short run remain fixed. b. variable inputs are rarely used. c. inputs that were fixed in the short run become variable. d. inputs that were variable in the short run become fixed.

Answer 1

Eventually in the long run in a firm, the inputs that were fixed in the short run become variable.

In a firm production, the factor of production including (land, capital entrepreneurship) are fixed in short run whereas, only labor factor is variable in the period.

• But when the firm is in long run, all factors of production and costs are already variable.

Hence, the Option C is correct because in the long run in a firm, the inputs that were fixed in the short run become variable.
