Answer to Question 1

Allocative efficiency is an efficiency criterion that describes a situation where the marginal benefit (or marginal valuation) of the last unit purchased is equal to the marginal cost of producing that unit. In other words, allocative efficiency occurs when production reflects consumer preferences. This is a significant concept in that all societies face scarcity which necessitates that societies make choices about what goods and services to produce. To maximize society's wealth, resources must flow to their highest valued use. This value is determined by consumers.

Answer to Question 2

The marginal propensity to consume, the marginal propensity to import, and the income tax rate all influence the magnitude of the multiplier. The multiplier is smaller when the marginal propensity to consume is smaller, when the marginal propensity to import is larger, and when the income tax rate is larger.
