Economics Course

I am now accepting bids to complete the following assignments for my Economics course:

 

8 quizes, 8 problem sets, 1 midterm, and 
1 final exam

 

Please reply or e-mail me with bids.  The amount that I listed is a starting point for negotiations.  This course has already begun and we are now entering the second week.  This course runs from now until the first week of September with one quiz and one set of problems due each week.

1. XYZ Corporation is a manufacturer of widgets. Over the past several months, it has been selling its widgets for $100 each and unit sales have averaged 5,000 units per month. This month its competitor, ABC, Inc. raised the price of its widgets from $100 to $110. XYZ noted that its unit sales increased by 200 units.

a. What is the cross price elasticity of demand between XYZ’s and AB C’s widgets?

b. If XYZ knows that the price elasticity of demand for its widgets is -2.0, what price would XYZ be able to charge and still sell 5,000 widgets, assuming ABC keeps its price at $110?

2. The demand function for bicycles in Mapleville is estimated to be

Qd = 2,500 + 10Y – 6 P

Where Y denotes income in thousands, Qd is the quantity demanded in units, and P is the price of bicycles. When P = $120, Y = 12,

a. What is the price elasticity of demand?

b. What is the income elasticity of demand?

3. A local realtor estimated the long-term income elasticity of demand for rental properties to be 0.9 and the long-run income elasticity for owner-occupied housing to be 1.10. Recent estimates indicate that income is forecast to rise at 5% per year over the next 2 years. What is the expected effect on the quantity demanded for rental housing and owner-occupied housing (assuming rental rates and the price of housing remain constant). If housing prices rise during the same period, how would the quantity demanded of each type of housing be affected?

4. Your market research group estimated the following demand curve for gadgets, the product your company produces and sells.

Qd = 4,000 – 40P

If this relationship between quantity demanded and prices continues to hold true in the future,

a. How many gadgets will be demanded at $10, $20, and $30?

b. What is the arc price elasticity between $10 and $20; between $20 and $30?

c. What is the point price elasticity at each of the three prices?

d. If your company sold 3,000 gadgets last year, what is the price it charged?

You have estimated the price elasticity of demand for an umbrella and found it to be inelastic. You can conclude that

a) if more umbrellas are sold as the result of a price decrease, total expenditures by consumers on umbrellas will decrease

b) changes in price do not affect the number of umbrellas demanded

c) the percentage change in price (in absolute value) is less than the percentage change in quantity demanded (in absolute value)

Which of the following reasons explains why the quantity demanded of a product decreases as the price of that product increases

a) as the price rises, the real income of the consumer decreases

a) quantity demanded of A will decrease

b) quantity supplied of A will decrease

c) demand for A will increase

d) demand for A will decrease

b) less than zero

c) equal to zero

d) equal to minus one

Consumers will be in equilibrium (maximize utility subject to income constraints) with respect to the consumption of two goods, A and B, if

a) the combination of A and B consumed is at a point on the consumer’s indifference curve that is tangent to the consumer’s budget constraint

b) the combination of A and B consumed is at a point on the consumer’s indifference curve where the slope of the indifference curve is greater than the slope of the budget constraint.

c) the combination of A and B consumed is at a point on the consumer’s indifference curve where the slope of the indifference curve is less than the slope of the budget constraint.

d) the marginal utility of both products is identical, regardless of the price
