If the marginal propensity to consume in a municipality is 0.8, what is the value of the simple multiplier? If a new stadium that adds $30 million in new consumption expenditures is built, what is the impact on the economy based on this multiplier? Suppose the Marginal Propensity to Import is 0.2, what happens to the multiplier and to the impact on the economy?

Total marketing effort is a term used to describe the critical decision factors that affect demand: price, advertising, distribution, and product quality. define the variable x to represent total marketing effort. a typical model that is used to predict demand as a function of total marketing effort is based on the power function: d = axb suppose that a is a positive number. different model forms result from varying the constant b. sketch the graphs of this model for b = 0, b = 1, 0< b< 1, b< 0, and b> 1. (we encourage you to use excel to do this.) what does each model tell you about the relationship between demand and marketing effort? what assumptions are implied? are they reasonable? how would you go about selecting the appropriate model?
