In the long run, if inputs are increased by 10 percent and output increases by 20 percent, then are said to exist. a. economies of scale b. constant returns to scale c. diseconomies of scale d. diminishing marginal returns

In the long run, if inputs are increased by 10 percent and output increases by 20 percent, then diseconomies of scale are said to exist. It is because diseconomies of scale is likely to happen in the long run for a business with increasing inputs without decreasing the cost of production. It can happen when the increase in production is dependent on one part that needs to be completed but there is a delay on producing the parts. Another reason is that the cost of shipping may increase base on how far will be the distance and the weight of the product.

Ithink the most approximate answer would be b.i hope it you!
