MARGINAL REVENUE PRODUCT AND FACTOR DEMAND: A perfectly competitive firm's factor demand curve is that negatively-sloped portion of its marginal revenue product curve. A perfectly competitive firm maximizes profit by hiring the quantity of input that equates factor price and marginal revenue product. As such, the firm moves along its negatively-sloped marginal revenue product curve in response to changing factor prices.

Now with bundle I (270 jogging shoes and 8 calibrators).- Producing 8 calibrators has added even more to the economy's capital.
- The cost of these 8 calibrators is 180 pairs of shoes compared to A, and the extra 4 calibrators compared to bundle E is 140 pairs of shoes.
- These 8 calibrators have increased the quantity of resources even more than bundle E, leading to an even greater shift of production possibilities curve.
- Tomorrow's production possibilities curve is even farther out than today's curve. There is more growth and a bigger shift in the curve.

INJECTIONS-LEAKAGES MODEL A macroeconomic model that balances non-consumption expenditures on production (injections) and non-consumption uses of income (leakages) that is used to identify the equilibrium level of, and analyze disruptions to, aggregate production and income. The injections-leakages model is based on the principles of Keynesian economics and provides an alternative to the standard aggregate expenditures (Keynesian cross) analysis. The three injections included in the model are investment expenditures, government purchases, and exports. The three leakages included in the model are saving, taxes, and imports. Three variations are the two-sector injections-leakages model (or saving-investment model), three-sector injections-leakages model, and four-sector injections-leakages model.
