How People Make Economic Decisions

Marginal costs and benefits are important in economics. Determining marginal cost is important in deciding whether or not to adjust the rate of production, where marginal benefits is the benefit gained in changing the rate of production. Without realization producers and consumers everywhere thinks about marginal cost and benefits. We all make decisions that are in our best interest. In another words, when we buy or produce items we ask our selves simple questions. Would it cost cheaper to buy one more item? Or dose it cost more to produce one more item? And what would be the benefit of acquiring one more item? People make decisions depending on there reasoning. Decision-making is also very important in economics; it can be simple yet complex.

The third is “rational people think at the margin”. People think marginally by taking action if and only if the marginal benefits exceed the marginal cost. Forth and last “people respond to incentives.” Responding to incentives mans people choose activities by comparing benefits to costs. Any change in either the benefits or the costs may change there behavior. Marginal cost is descried by investopedia.com as the opportunity cost associated with producing one more additional unit of a good. Let’s use shirts for example, by looking at the marginal cost of printing 13 shirts instead of 12. The cost of printing 12 shirts is $120 and the cost of printing 13 shirts is $126. The marginal cost of printing that extra shirt is $6. We noticed that the total cost always increases as the number of shirts increase. Marginal benefit is described by investopedia.com…
