Question 1

A time series graph can show both the level of a variable and the speed with which the variable changes over time.

Accepted Answer

A time series graph displays changes in the level of a variable over time, as well as the speed of those changes. The slope of the line connecting the data points on the graph represents the rate of change of the variable over time.

Question 2

The chain-weighted output index

Accepted Answer

The chain-weighted output index is a method of calculating real GDP that uses a weighted average of prices from the current year and the previous year. This method is considered more accurate than using only the current year's prices because it takes into account changes in relative prices over time. The option D is incorrect because the chain-weighted output index is widely used by government agencies and economists to measure economic growth.

Question 3

Valuing the quantities of goods produced in consecutive years using prices in both years and then averaging the percentage changes in the value of output is part of the ________ method of calculating real GDP.

Accepted Answer

The chain-weighted output index method of calculating real GDP involves valuing goods produced in consecutive years using prices in both years, and then averaging the percentage changes in the value of output. This method is more accurate than the fixed quantities/variable prices method, as it takes into account changes in relative prices over time. It is also more flexible than the base-year and moving-base-year methods, as it allows for changes in the composition of output over time.

Question 4

The chain-weighted output index method of calculating real GDP compares

Accepted Answer

The chain-weighted output index method involves comparing the quantities of goods produced in consecutive years using prices from both years and then averaging the percentage changes in the value of output. This approach helps to more accurately reflect changes in the economy's output by taking into account changes in both quantities and prices over time.

Question 5

The chain-weighted output index method ________.

Accepted Answer

The chain-weighted output index method uses the prices of two adjacent years to calculate the real GDP growth rate. Choice A is incorrect because nominal GDP is calculated using current prices, not the prices of a base year. Choice B is incorrect because the chain-weighted output index method takes into account price changes over time. Choice C is incorrect because real GDP can decrease in a given year if the output declines or the price level rises faster.

Question 6

What kind of information is conveyed in a time-series graph?

Accepted Answer

The answer of What kind of information is conveyed in...

Question 7

-The figure above shows the price of a DVD player from 2003 to 2007.
a)What type of graph is illustrated above?
b)What is the trend in the price of a DVD player?

Accepted Answer

The answer of 
-The figure above shows the price of...

Question 8

At 2015 prices, the value of production in 2016 was 6 percentage points higher than in 2015. At 2016 prices, the value of production in 2016 was 4 percentage points higher than in 2015. Using the chain-weighted output index, real GDP is ________ in 2016 than in 2015.

Accepted Answer

The chain-weighted output index measures changes in real GDP while accounting for changes in prices from year to year. Since the value of production increased by 6% at 2015 prices and by 4% at 2016 prices, it suggests that prices increased between 2015 and 2016. The chain-weighted output index accounts for these price changes, so we can assume that the increase in value of production translates into an increase in real GDP. Therefore, real GDP in 2016 is 5% greater than in 2015.

Question 9

On a time-series graph with a ratio scale

Accepted Answer

On a time-series graph with a ratio scale, the vertical axis represents the variable being measured, and because it is a ratio scale, the distance along the vertical axis represents different amounts of the variable. Therefore, choice B is correct. The slope of the line can be positive or negative depending on whether the variable is rising or falling over time, so choice A is incorrect. Time is always plotted on the horizontal axis in a time-series graph, so choice C is incorrect. Finally, a trend can be determined by analyzing the slope and direction of the line, so choice D is also incorrect.

Question 10

The chain-weighted output index method of measuring real GDP is based on

Accepted Answer

The chain-weighted output index method calculates real GDP by using the prices of two adjacent years to calculate the growth rate, and adjusts for changes in relative prices between years. This method is considered more accurate than using a fixed base year, as it accounts for changes in the economy's production structure over time. Option A is incorrect as this method does not use current prices, but rather a weighted average of prices across adjacent years. Option B is incorrect as there is no averaging over a specific time period. Option D is incorrect as averaging nominal and real measures of GDP would not necessarily lead to a more accurate figure.

Question 11

You believe that the total amount of goods produced in the United States has generally increased over the years. In a time-series graph illustrating the total amount produced, you expect to find

Accepted Answer

If the belief is that the total amount of goods produced in the United States has generally increased over the years, then the expected pattern on a time-series graph would be an upward trend. This is because an upward trend indicates an increase in the variable being measured (in this case, the total amount of goods produced) over time.

Question 12

Real GDP in 2015 is $10 trillion. Between 2015 and 2016, using 2015 prices, GDP grew 3 percent and using 2016 prices real GDP grew 7 percent. Using the chain-weighted output index method, real GDP in 2016 is ________ trillion.

Accepted Answer

The answer of Real GDP in 2015 is $10 trillion....

Question 13

Which of the following is TRUE regarding the chain-weighted output index method?
I.It is the method used to measure the growth rate of nominal GDP.
II.It uses data from the current year and from the previous year.
III.It is a method of measuring the growth rate of real GDP.

Accepted Answer

The chain-weighted output index method is used to measure the growth rate of real GDP, not nominal GDP. It uses data from the current year and from the previous year to calculate the change in real output. Therefore, statements II and III are true, but statement I is false.

Question 14

A graph shows the wages of factory workers. The slope of the line is positive for periods when the wage rate is

Accepted Answer

The slope of a line represents the rate of change. If the slope is positive, it means that the variable on the y-axis (wage rate) is increasing as the variable on the x-axis (period of time) increases. Therefore, the wage rate is rising during periods when the slope of the line is positive.

Question 15

A trend is a general tendency for a variable to increase or decrease over time.

Accepted Answer

A trend refers to a general pattern or tendency for a variable to increase or decrease over time.
