ASSUMPTION: An initial condition or statement that sets the stage for an analysis by abstracting from the real world. Assumptions are important to economic theories and economic analysis. Some assumptions are used to simplify a complex analysis into more easily manageable parts. These establish idealistic benchmarks that can be used to evaluate real world conditions. Other assumptions are used as control conditions that are subsequently changed to evaluate the effect of the change. The use of ceteris paribus assumptions in comparative statics analysis is an excellent example.

Lesson 4: Production Possibilities | Unit 3: The Curve

Page: 9 of 24

We can transform the schedule of production possibility numbers into a graph.- Each bundle can be represented by a point in two dimensional production possibilities space.
- The two dimensions of the space are clock calibrators on the horizontal axis and jogging shoes on the vertical axis.
- The horizontal axis is measured between 0 and 11 calibrators.
- The vertical axis is measured between 0 and 500 jogging shoes.
- The two axis are joined at the origin.
- The plotted bundles form a semi-circle pattern.
- If these were stars in the night sky we might name it the arc of production. But it's not, so we won't.

SAVING-INVESTMENT MODEL A variation of the Keynesian injections-leakages model that includes the two private sectors, the household sector and the business sector. This variation, more formally termed the two-sector injections-leakages model, captures the interaction between induced saving (and indirectly induced consumption expenditures) and autonomous investment expenditures. This model provides an alternative to the two-sector aggregate expenditures (Keynesian cross) analysis of the macroeconomy, including equilibrium, disequilibrium, and the multiplier. Equilibrium is identified as the intersection between the saving line and the investment line. Two related variations are the three-sector injections-leakages model and the four-sector injections-leakages model.

Today, you are likely to spend a great deal of time looking for a downtown retail store wanting to buy either a birthday greeting card for your aunt or a wall poster commemorating the moon landing. Be on the lookout for cardboard boxes.
