Question 17One problem with the CPI is the "substitution bias," which refers to consumers buying more of a good that has becomecheaper and less of a good that has become more expensive. Assume that consumers consider Pepsi and Coke to besubstitutes, so that when the price of Coke increases, consumers purchase less Coke and more Pepsi. When the CPI iscalculated following the increase in the price of Coke, the substitution bias causes the CPI toO understate inflation since both the increase in the price of Coke and the increase in the amount of Pepsi purchased enterthe CPI calculationO understate inflation since only the decrease in the price of Pepsi enters the CPI calculationO overstate inflation since both the increase in the price of Coke and the decrease in amount of Coke purchased enter theCPI calculationoverstate inflation since only the increase in the price of Coke enters the CPI calculation

(b) “Like the CPI, the GDP deflator is subject to substitution bias.” True or false? Explain. (c) “Unmeasured quality change generally causes the CPI to overstate the actual increases in the cost of living.” True or false? Explain.

In Felixania, cat food constitutes 45 percent of the typical basket of goods for a typical consumer, dog food constitutes 3 percent, and all other goods constitute the remaining 52 percent. Assume the price of cat food rises by 4 percent, the price of dog food falls by 10 percent, and prices remain constant for all other goods. Based on the information given, we can definitely say CORRECT ANSWER: the consumer price index (CPI) in Felixania is more than in the previous year. Note:- Do not provide handwritten solution. Maintain accuracy and quality in your answer. Take care of plagiarism. Answer completely. You will get up vote for sure.
What is the effect of the sources of bias on the CPI calculation? A. Changes in relative prices lead consumers to change the items they buy, and the CPI reflects this substitution. B. The new goods bias injects a downward bias into the CPI. C. When faced with higher prices, people use discount stores more frequently and convenience stores less frequently, but the CPI doesn't include this outlet substitution. D. When the quality of a good improves over time, the CPI doesn't include the portion of the price rise attributable to the higher quality in its calculation.
Indicate which one of the following events will affect CPI ONLY. Oa Saudi Arabia successfully developing a vaccine for Covid-19 which is used locally as well as exported to other countries. Ob. There is a decrease in the price of meat imported from Australia. Oc.There is an increase in the price of eggs produced in Saudi Arabia Od. People buying more imported goods without any change in prices O Saudi Arabia changes its base year to 2020
Suppose that over time, households used flash sale online retailers at an increasing rate. As a result the CPI is likely to be Select the correct answer below: O underestimated because households would buy products at lower prices than those collected by the U.S. Bureau of Labor Statistics underestimated because households would buy products at higher prices than those collected by the U.S. Bureau of Labor Statistics overestimated because households would buy products at lower prices than those collected by the U.S. Bureau of Labor Statistics overestimated because households would buy products at higher prices than those collected by the U.S. Bureau of Labor Statistics
The table below gives the CPI and the price of gasoline per gallon in the fictitious country "Alpha" between 2010 and 2015. For each year find the percent change in the price of gasoline from the previous year's price, the CPI inflation rate, and the change in the relative price of gasoline. Instructions: Enter your responses rounded to two decimal places for change in gasoline price and inflation, and one decimal place for percent values in the relative price change. If you are entering any negative numbers be sure to include a negative sign (-) in front of those numbers. Year Gasoline price ($/gallon) Percent change in gasoline price CPI Inflation Change in relative price of gasoline 2010 $0.80 — 1.60 — — 2011 $1.00 % 1.80 % % 2012 $1.25 % 2.00 % % 2013 $1.65 % 2.04 % % 2014 $1.70 % 2.21 % % 2015 $1.87 % 2.25 % %
Assume that people in an economy only consume the following goods shown in the table: Rice Meat Juice Year 1 price P2 P4 P1 Year 1 quantity 100 100 200 Year 2 price P2 P6 P2 Year 2 quantity 100 100 200 Calculate the % change in the price of every goods. Using the same method with the CPI, calculate the % change of the overall price level. If you were to learn that juice increased in size from Year 1 to Year 2, should that information affects your calculation of the inflation rate? If so, how? If you were to learn that juice introduced new flavors in Year 2, should that information affect your calculation of the inflation rate? If so, how?
Because consumers can sometimes substitutecheaper goods for those that have risen in price,a. the CPI overstates inflation.b. the CPI understates inflation.c. the GDP deflator overstates inflation.d. the GDP deflator understates inflation.
Based on surveys conducted by the BLS, the CPI basket assigns a weight of approximately 15% to transportation spending. Suppose you walk to your workplace every day and you do not use any other means of transportation. With everything else the same, if the price of transportation services increases by 10%, by how much would the CPI increase? Is the CPI measuring the true change in your cost of living?
The price of a brand-name laptop is $1,000 in 2018 and $1,100 in 2019. How could this price rise inject a bias into the CPI? A. If students buy more generic laptops when brand-name laptops experience a rise in price but the BLS ignores this commodity substitution, then the CPI understates inflation. B. If students buy their laptops online instead of in brick-and-mortar stores but the BLS ignores this outlet substitution, then the CPI understates inflation. C. If the laptop quality has increased but the BLS counts most of the price rise as inflation, then the CPI overstates inflation. D. The CPI has a bias of 1.1 percent a year regardless of price changes.
Many elderly people in the US receive Social Security payments as their sole source of income. Because of this, there have been attempts to adjust these payments so as to keep up with changing prices (inflation). This process is called “indexing”; this question will lead you through the process. Suppose that in the year 2018, a typical Social Security recipient consumed only Food (F) and Housing (H). The price of housing was $150/unit and the price of food was $50/unit. Denote the quantities of food and housing per month by F and H respectively. This consumer received $1500/month and consumed 5 units of housing and 15 units of food. (a) Write out the consumer’s budget constraint and demonstrate that the bundle chosen falls on that budget constraint. (b) Draw the budget constraint on a graph (Housing on the horizontal axis) with the optimal bundle labeled. Draw the indifference curve through that optimal bundle. Assume preferences are well behaved. Suppose that in 2019, the price of…
The CPI index is calculated for consumers with the Cobb-Douglas utility function u(x,y)= xy2 over goods food (x) and clothing (y), where the reference basket is A = (10,20) , that is 10 units of food and 20 units of clothing. The initial prices are px = py = 1 and the final prices are px = 2, py = 16. (a) Calculate the CPI (consumer price index) which is the ratio of the cost of the basket A under the final prices divided by its cost under the initial prices. (b) Naturally, given the prices increase disproportionately, we can expect the consumer not to stick with the basket A but choose another basket B where she achieves the same utility level as in A, but which costs much cheaper, under the final prices. Calculate the basket B which is the cheapest bundle under the final prices to achieve the utility level of A. Calculate the effective CPI, which is the cost of basket B under the final prices divided by the cost of A under the initial prices. This reflects the real increase in…
