Final answer:
An economist would call a 'good deal' on a product a consumer surplus. In finance, getting a good deal might relate to the present discounted value of an investment if market interest rates change after a bond's issue. The term also encompasses the social benefits of economic transactions, like reduced waste from resale operations.
Step-by-step explanation:
When a buyer acquires inventory at a discounted price, an economist might refer to the scenario as a buyer benefiting from consumer surplus, which is the difference between what a consumer is willing to pay for a good or service and what they actually pay. Similarly, when considering financial transactions, such as the purchase of a bond, the concept of present discounted value applies. This is especially relevant if market interest rates change after the bond is issued, affecting the bond's sale price compared to its face value.
From another perspective, when a company, like Junkbuyers Company, purchases items for resale, not only do the buyer and seller derive private benefits, but there are also social benefits due to reductions in waste and associated disposal costs. This illustrates how transactions can have larger impact beyond the immediate trading parties.
