When estimating wage equations we expect that young, inexperienced workers will have relatively low wages and that with additional experience their wages will rise, but then begin to decline after middle age, as the worker nears retirement. This life-cycle pattern of wages can be captured by introducing experience and experience squared to explain the level of wages. If we also include years of education and a dummy variable for the sex (0 if male, 1 if female) we have the following equation:
W AGE = β1 + β2 EDUC + β3 EXPER + β4 EXPER^2 + β5 SEX + e
a. What is the marginal effect of experience on wages?
b. What signs do you expect for each of the coefficients β2, β3, β4 and β5 Why?
c. After how many years of experience do wages start to decline (Since you are not provided with OLS estimates of the regression coefficients, cast your answer in terms of the theoretical coefficients β).

Peppy roaney believes that pizza is a much more versatile dish than most people realize. as the national marketing manager for pizza guys, he observed how consumers were delighted with barbecue pizza, hawaiian pizza, mexican pizza and other unique combinations. his suggestions for other unusual pizzas, however, were met with a negative response by his superiors. even some of his colleagues laughed at his ideas. peppy's confidence in his ability to understand the market has led him to focus on planning a business of his own. peppy realizes that he will take a risk when he leaves his job with pizza guys and embarks upon a new venture: peppy's pizzazzeria. peppy is excited about the potential of profitably catering to the unmet desires of pizza consumers. peppy is confident that peppy's pizzazzeria will be a success, but only if he has enough money to do things right. since peppy has very little personal wealth, he knows he must obtain financial assistance. in order to prepare for meetings with bankers and p
