1.4 Marginal Analysis and Decision-Making Models

Multiple Choice

Which of the following best describes the concept of marginal analysis in economics?

• Making decisions based on total costs and benefits

• Making decisions based on additional (incremental) costs and benefits

• Making decisions without considering costs

• Making decisions based on past experiences

Multiple Select

Which of the following are key economic assumptions?

• Society has unlimited wants and limited resources

• Everyone makes decisions by comparing marginal benefits and marginal costs

• Every choice has no cost

• Real-life situations can be explained through simplified models and graphs

Open Ended

Describe a situation where the marginal cost is greater than the marginal benefit. What decision should be made in this scenario?

Multiple Choice

What does the downward-sloping Marginal Benefit (MB) curve in the first graph represent in terms of pizza consumption?

• Each slice of pizza gives more and more additional benefit

• Each slice of pizza gives less and less additional benefit

• The cost of each slice of pizza increases

• The total benefit of all pizza slices increases

Multiple Choice

How does the Marginal Cost (MC) curve in the second graph differ from the Marginal Benefit (MB) curve in the first graph?

• MC decreases while MB increases

• MC increases while MB decreases

• Both MC and MB increase

• Both MC and MB decrease

Why is 5 slices the optimal amount?

Multiple Choice

Which of the following scenarios represents 'Not Enough' pizza according to the graphs?

• When MB < MC

• When MB = MC

• When MB > MC

• When MC = 0

Multiple Choice

What happens when the quantity of pizza consumed is greater than the optimal amount, according to the graphs?

• Marginal benefit exceeds marginal cost

• Marginal cost exceeds marginal benefit

• Total benefit is maximized

• No additional cost is incurred

Multiple Choice

At what point is the optimal quantity of pizza produced according to the graph?

• Where MB > MC

• Where MB < MC

• Where MB = MC

• Where MC = 0

Multiple Choice

What is the definition of marginal utility?

• The total satisfaction from consuming all units of a good or service.

• The additional satisfaction or benefit a consumer gets from consuming one more unit of a good or service.

• The cost of producing one more unit of a good or service.

• The decrease in satisfaction from consuming additional units of a good or service.
