There is a proverb​ "anything worth doing is worth doing​ well."   Do you think an economist would agree with this​ proverb? A. ​No, because doing something well has no next best alternatives with which to compare. B. ​Yes, because the marginal of extra effort is typically as effort increases. C. ​Yes, because doing something to the best of your ability is optimizing behavior. D. ​No, because the marginal cost of extra effort may be greater than the marginal benefit. E. ​, because the total net benefit of extra effort is by definition.

D. ​No, because the marginal cost of extra effort may be greater than the marginal benefit.

Explanation:

Marginal cost can be defined as the additional or extra cost that is being incurred by a company as a result of the production of an additional unit of a product or service.

Generally, marginal cost can be calculated by dividing the change in production costs by the change in level of output or quantity.

Utility can be defined as any satisfaction or benefits a customer derives from the use of a product or service.

This ultimately implies that, any satisfaction or benefits a customer derives from the use of a product or service is generally referred to as a utility.

Furthermore, the marginal utility of goods and services is the additional satisfaction that a consumer derives from consuming or buying an additional unit of a good or service.

Hence, an economist wouldn't agree with the proverb (anything worth doing is worth doing well.) because the marginal cost of extra effort may be greater than the marginal benefit.

This ultimately implies that, the satisfaction that an individual such as an entrepreneur would derive from putting in more efforts into a business would be lesser than the cost incurred. As a result, he would not benefit anything or generate profit from his efforts.
