In a supply-
- The price of taco increases.
- All hamburger sellers raise the price of their French fries.
- Income falls in town. Assume that hamburgers are a normal good for most people.
- Income falls in town. Assume that hamburgers are an inferior good for most people.
- Hot dog stands cut the price of hot dogs.
Concept Introduction:
Normal Goods: Normal goods are those goods which have a direct relationship between the income and quantity demanded. When income increases the quantity demanded also increases and vice versa.
Substitute goods: Substitute goods are otherwise known as alternative goods which are used for the same purpose e.g. Tea and Coffee.
Complementary goods: The complementary goods are those goods are used together. For e.g. pen and ink.
Inferior goods: The inferior goods are those kinds of goods it demanded decreases when the income of the people increases for e.g. Potatoes.

- Problem 2 Endogeneity Suppose you are interested in how social media usage affects students' academic performance. Consider the following model: GPA; = ßo + ß₁Social Media Hours; + ɛ; where GPA, is the grade point average of a student and Social Media Hours; measures how many hours the student spends on social media every week. Each student is denoted by the subscript i. a. What is the dependent variable Y in this setting? What is the independent variable X in this setting? (4 points) b. What does Bo C. What does ẞ1 = 3 mean? (2 points) = 0.2 mean? (3 points) d. What is the condition for the independent variable Social Media Hours; to be endogenous? (5 points) e. Is the independent variable likely to be endogenous? Why or why not? (3 points) f. If yes, describe a scenario where the independent variable is endogenous.

- Round Tree Manor is a hotel that provides two types of rooms with three rental classes: Super Saver, Deluxe, and Business. The profit per night for each type of room and rental class is as follows. Rental Class Super Saver Deluxe Business Room Type I Type II $30 $35 $20 $30 $40 Round Tree's management makes a forecast of the demand by rental class for each night in the future. A linear programming model developed to maximize profit is used to determine how many reservations to accept for each rental class. The demand forecast for a particular night is 140 rentals in the Super Saver class, 50 rentals in the Deluxe class, and 40 rentals in the Business class. Round Tree has 100 Type I rooms and 120 Type II rooms. (a) Formulate and solve a linear program to determine how many reservations to accept in each rental class and how the reservations should be allocated to room types. (Assume S₁ is the number of Super Saver rentals allocated to room type I, S₂ is the number of Super Saver…arrow_forwardDon't used hand raitingarrow_forwardWhat is the impact of population and demographic trends on our society?
