Exercise 4.
Mary is investigating the determinants of house prices in 90 cities. She gathers information on house
value in log (Inhseval), the size of the house (sizehse), and income per capita in log (Inincome). She
also gathers information on the property tax rate, specifically if cities have the low property tax rate
(less than 2.5%), or the high property tax rate (2.5% or more). She runs the following regression:
Ln(hseval;)= a + B₁(sizehse;) + B2 (income)+ &;
And then she separates the regression by low and high property tax rate.
The results of her regression analysis are given in the tables below.

Given what you have learned about 1) demand (and its determinants) and quantity demanded and 2) supply (and its determinants) and quantity supplied. Analyze the following hypothetical situation. All postings should be made individually.
Peanut crops have been destroyed by a fungus. Consumers are substituting almond butter for peanut butter because they perceive it to be a healthier option. The prices of both peanut butter and almond butter are rising. Why?
The following regression model investigates the determinants of years of schooling.
educ = Bo + B₁ * motheduc + B₂ fatheduc + ß* income +84 * ability + u
where motheduc is mother's education, fatheduc is father's education, sibs is number of siblings, and ability is a person's ability.
Write the reparameterized model and explain how you would use it to test the hypothesis that mother's education and father's education have the same effect on years of schooling.

This time the merchant has on hand 30 kilograms of Colombian beans, 15 kilograms of Kenyan beans, and 15 kilograms of French roast beans. Suppose one bag of the house blend produces a profit of $0.50, one bag of the special blend produces a profit of $1.50, and one bag of the gourmet blend produces a profit of $2.00.

If the population of mice is kept below a certain level no person will get sick (because the mice will live in the forest) but if it goes above a level then people will get ill.

- The equation for a straight line (deterministic model) is y=β0+β1x. If the line passes through the point (−10,10), then x = −10, y = 10 must satisfy the equation; that is, 10=β0+β1(−10). Similarly, if the line passes through the point (3,12), then x = 3, y = 12 must satisfy the equation; that is, 12=β0+β1(3). Use these two equations to solve for β0 and β1; then find the equation of the line that passes through the points (−10,10) and (3,12). A. Find β0 and β1. β1 = β0 = (Simplify your answers.
