OPPORTUNITY COST: The highest valued alternative foregone in the pursuit of an activity. This is a hallmark of anything dealing with economics--and life for that matter--because any action that you take prevents you from doing something else. The ultimate source of opportunity cost is the pervasive problem of scarcity (unlimited wants and needs, but limited resources). Whenever limited resources are used to satisfy one want or need, there are an unlimited number of other wants and needs that remain unsatisfied. Herein lies the essence of opportunity cost. Doing one thing prevents doing another.

TWO-SECTOR KEYNESIAN MODEL A Keynesian model of the macroeconomy that includes the two private sectors, the household sector and the business sector. This Keynesian model variation, often termed the basic Keynesian model or the private sector Keynesian model, captures the interaction between induced consumption expenditures and autonomous investment expenditures. This model is commonly used to illustrate the basic workings of Keynesian economics, including equilibrium, disequilibrium, and the multiplier. Equilibrium is identified as the intersection between the C + I line and the 45-degree line. Two related variations are the three-sector Keynesian model and the four-sector Keynesian model.

Taking A Ride On TRANSPORTATION INFRASTRUCTUREOur pedestrian excursion gives us a ground-level view of the economy, but it's certainly slow and time-consuming. If you're like me, you've probably thought once or twice about jumping into an Omni Motors XL GT 9000 sports coupe to speed us along the way. Or perhaps an Omni Airlines 30-day tourist excursion would make our trip faster and less exhausting. That's one nice thing about modern transportation, it's pretty quick and not too expensive. It also helps us get a whole lot closer to solving the unsolvable problem of scarcity. However, for a really good pedestrian view of transportation and how it helps us along, we'd better remain on foot.
