Document Summary

Submit this book for full credit on your exam. Long questions 3 questions 50 points total. List three reasons that birth rates may suffer from micro-inertia. You do not need to draw a diagram or solve an equation. (i) an increase in the family"s non-wage income. We would expect to see an increase in the demand for children if children are a normal good. The family now has more money to spend on everything. (ii) an increase in the mother"s wage. The opportunity costs of children increase because the mother"s time is worth more, so we should see a decrease in demand. On the other hand, the family"s income also increases, and so demand should increase, as explained in (i). We can"t say whether the total effect is positive or negative. (iii) a decrease in the returns to education. This should increase the family"s demand for kids.

For the record, this is a homework question. A statistics student wishes to understand the relationship between a used car's price and the number of miles that car has been driven. The student goes to a local car lot and writes down the prices and the odometer reading for 100 cars. The student takes this information and completes a regression. The goal is to examine how the miles drove impacts the car's price. The regression output appears at the end of this assignment. Use the output to answer the following questions.

a) (3 points) Dependent variables Independent variable

b) (8 points) Do you expect a positive, negative, or no relationship between miles driven and price? Draw a scatterplot that corresponds to your relationship.

Be sure to include which variable (miles or price) is on the x-axis and which is on the y-axis.

b) (3 points) Write the regression equation (I want the specific estimates for the coefficients)

c) (3 points) What is the interpretation of the slope coefficient of b 1 (in terms of this problem)?

d) (4 points) Is b 1 significant from zero? How do you know?

e) (3 points) Use the regression equation to predict the price for a car that was driven for 30,000 miles. Is this mileage appropriate to make a prediction? Why or why not?

f) (3 points) Use the regression equation to predict the price for a car that was driven for 80,000 miles. Is this mileage appropriate to make a prediction? Why or why not?

g) (3 points) What percentage of price variation is explained by the variation in miles driven?

This week you have read about the effects of strategy switching and what happens when Industrial policy becomes the driver in the development process. The need to search for and promote dynamic comparative advantage is very important at the national level. Appropriate institutions at the national and local levels need to support warranted strategy switches.

As an executive you are asked to produce a PowerPoint presentation where you are:

1) Explaining the effects of the national-level strategy switching on the local level.

2) Develop a short-term strategy addressing the need to look and promote a dynamic comparative advantage (in terms of products, services etc. ) that needs to be supported locally.

3) Suggest how local public or private institutions can support warranted strategy switches at the local level.

In max. 12 sppt. slides present your points. APA style

Note: 1. the book is: Economics of Development, 7th Ed. for Perkins

Note 2: you can write it as a paragraph and I will transform it into PowerPoint

Note 3: you can ready about comparative advantage for David Ricardo through these links
