INTRODUCTION:

GDP (Y) is the measure of the value of all final goods and services bought for their final use in an economy for a given time period.

The model of the circular flow of income makes it apparent that, in a given time period, income equals amount of expenditure which in turn equals the value of output sold in the economy as a whole.

Income = Expenditure = Output (Value Added)

Therefore, there are three methods to measuring GDP. These are the Income, Expenditure and Output methods.

The income method measures GDP by adding together the total of all factor incomes paid to households by firms for the use of resources. Incomes are divided into 5 categories: compensation of employees, interest for capital, rental income, profits for entrepreneurship and proprietor’s income. Seeing as incomes are calculated at factor cost rather than market price, further adjustments must be made to calculate GDP. Indirect business taxes and depreciation incurred must be added and subsidies subtracted.

Y = Income + Depreciation + Indirect Business Taxes
+ Net Income - Subsidies

The expenditure method measures GDP by adding together all expenditures on all final goods and services made by all sectors of the economy. Expenditure is divided into 4 categories: Consumption Expenditure (C), Investment (I), Government Purchases of goods and services (G) and Net Exports (Exports – Imports) (NX).

Y = C + I + G + NX

The output method measures GDP by adding together the total of the value added at each stage of production made by all sectors in the economy.

Value Added = Sales – purchases of working capital? ? ?

Real Gdp vs. Nominal Gdp

...Real GDP vs. Nominal GDP Real GDP is GDP adjusted for changes in the price level and Nominal GDP is GDP expressed at current prices and it is often called money GDP (Gwarthney, pg. 732 & 734). Both the Real GDP and Nominal GDP are from the GDP deflator which is measurements of money and power that are the effects of inflation. The Real GDP is the measurements of significant of price changes and Nominal GDP is the measurements of inflation. We need both Real GDP and Nominal GDP because both plays important roles in the economics system and both are use to keep up with the comparison of years, prices, price index, and real GDP with percentage increases between of the area noted. In my first article, Wall Street Journal, it took place in Japan around the 2000 about the fourth quarter concern because instead of the prices rising they are progressively declining among other nations are excelling. I paid attention in the first 2 quarters real and nominal were the same but on the last two it change the nominal gdp became poorer then the real gdp. In which is bad because the products of goods and services determined the inflation and real growth in which is the numbers economics look for to increase because it’s the profit that counts. I suggest that Japan needed to reevaluate a plan to increase their products and sells so the inflation and real gdp and the nominal which is the money would increase in the world trade sells.

For the CPI, assume that the representative basket of goods is exactly the one produced in the year 2007 Answer: To calculate nominal GDP for 2007 is $20, 000 ∗ 100 + $1.25 ∗ 400, 000 + $2 ∗ 100, 000 = $2, 000, 000 + $500, 000 + $200, 000 = $2, 700, 000 for 2008 $21, 000 ∗ 120 + $1.50 ∗ 380, 000 + $2.1 ∗ 115, 000 = $2, 520, 000 + $570, 000 + $241, 500 = $3, 331, 500 To calculate real GDP for 2007, since 2007 is the base year real GDP 2007 equals $2,700,000 1 for 2008 just use the 2007 prices $20, 000 ∗ 120 + $1.25 ∗ 380, 000 + $2 ∗ 115, 000 = $2, 400, 000 + $475, 000 + $230, 000 = $3, 105, 000 The amount of stuff produced in 2008, at 2007 prices is the real GDP in 2008 To calculate the GDP deflator in both years simply divide Nominal GDP by Real GDP, so for 2007 GDP def lator 2006 = $2.7 million/$2.7 million = 1 and for 2008 GDP def lator 2007 = $3, 331, 500/$3, 105, 000 = 1.073 For the CPI , just calculate it as a Laspeyres price index so that a0 pat + b0 pbt + c0 pct CP It = a0 pa0 + b0 pb0 + c0 pc0 where a stands for autos and b stands for bread.

...How Exports impact GDP Tiffany Cook March 19, 2015 Econ 214 (gwartney, 2015) “Gross domestic import is the market values of all final goods and sales” There are various factors that make up the subcategories of the United States, Gross domestic product. This definition tells us how we ultimately arrive at a calculations of the gross domestic products, but it does not shed light on the economies output and input and the benefits or setbacks each service may have. Some ways that we can look at expenditure approach is to know the wealth of what our goods and services can provide, also how these goods and services can be a come up or a setback dependent upon what we do more of. The expenditure approach allows us to see what our consumers have been benefiting from with the goods and services that have been provided to them by the US. Foreigners make up a portion of the GDP with imports, but in order for us to be on the winning side we would have to provide other countries with more of our products for them to buy or consume. Therefore the greatest impact on GDP is what we export in order to gain a profit from the consumer. If we were the consumer we would be looking to do the same. The economies main goal is to make the money and keep more of it. Exports allow us to do more of that, imports gives us resources to supply the source products for us to export. (Deekay, 2009)States that “export instability stimulates inflation. When inflation rises in a country the products tend...

Analysis on M2 & Cpi of China, 1990-2014

...Analysis on M2 & CPI of China, 1990-2014 The chart below demonstrates the broad money (M2) and Consumer Price Index (CPI) of China during the period of 1990 to 2014. The data is picked from the official website of the National Bureau of Statistics of China. (Data source: National Bureau of Statistics of China) According to the graph, both two figures show an uptrend in last three decades, and they shows a positive correlation. The M2 of 1990 was only about 1,500 billion yuan, and it increased gradually in the next decade. The growth rate of the CPI kept raising every year, and after the year of 2008 it witnessed a remarkable rise, reaching at 122,840 billion yuan in 2014, which is 80 times of the figure of 1990. At the same time, the CPI ascended from 216.4 in 1990 to over 600 in 2014. During 1993 and 1996, the increase was apparently more rapid than other years. However, in 2009 the number decreased slightly, and this is the only year in which it goes down. The increase of paper money accelerates the raising speed of M2, and as a result the CPI goes up as well. During 1993 to 1996 the growth rates of CPI were almost 25%, which is incredibly high. Serious inflation was happened around that period, and it turned better between 2000s. In 2010s, however, the bad circumstance seems back again. The amount of M2 rocketed dramatically during the past few years, and it may cause another serious inflation in the near future if the government do not take effective measures...

Gross Domestic Product

Economists measure growth with changes in real gross domestic gross domestic product (real GDP)---the market value of final goods and services produced in economy stated in the prices of a given year (McGraw-Hill 155). In plain simple terms gross domestic product is the economic report card of the United States. The parts that make up GDP are: Growth where when production and sells are good income is good with a growing economy with total output and total income increasing. Business cycle is the upward or downward movement of the economic activity that occurs around the growth trend (McGraw-Hill 158). The business cycle phases are: The peak, The downturn, The trough, and The upturn Unemployment in where a percentage of people who are fully capable of working but they can’t attain employment. Unemployment is social problem and a government problem. Inflation is a continual rise the price level. The consumer price index (CPI), the producer price index (PPI), and the GDP deflator are all price indexes used faced by producers (McGraw-Hill 158).

Does the Consumer Price Index Overstate Inflation and Changes in the Cost of Living?

...At the end of 1996, a study of the Consumer Price Index was done under the leadership of Michael Boskin in which they declared that the CPI has been overstated and that the index should have been at a rate of 1.8% as opposed to the reported amount of 2.9%. His report also included that the CPI had been overstated similarly of the past twenty years. The finding in his report shows that the government was doing a good job at controlling inflation and that productivity was higher than previously reported. Since our government uses index to adjust stats such as GDP per capita, a reduction in CPI shows our economic performance as improved. We cannot afford to take his report into consideration as there are many flaws and deceptions in his findings. The CPI is made up of many details below are a few key points that will help that will help to reveal the flaws and deceptions regarding Boskin’s determination.

Analysis of the Macroeconomic Environment Within the Health-Care

...This report discusses macroeconomic factors that impact both the automotive and health-care industries. Interest rates, consumer price index (CPI), consumer confidence, Gross Domestic Product (GDP), wage rates, and inventory levels impact the macroeconomic environment to influence these industries in the short run. Consumption as a percentage of the GDP depicted in table 1 indicates a continuous declined in consumer spending from 2005 through 2010 and suggests that consumers are becoming more conservative with disposable income spent on elective health-care products and procedures as-well-as new vehicle purchases. As the nominal interest rates indicate in table 2, the FED attempted to encourage consumer spending by decreasing the interest rates to encourage expansionistic economic activity, which would also be a positive influencing factor for both the health-care and automotive industries. The automobile industry is volatile by nature and heavily influence by macroeconomic factors, while the health-care industry enjoys an inelastic environment. Macroeconomic factors influence the health-care industry, it is unlikely essential health-care demand will decrease in the short term; however, elective health-care products and services will likely suffer as will new vehicle purchases as consumers remain conservative. The future is not as bleak as one might anticipate. The automotive industry is traditionally volatile and dependent upon the macroeconomic environment and currently producing...

...measure of economic well-being – real, per capita GDP. Further, if we want to see how our economic well-being is changing over time, we can calculate how real GDP is changing in percentage terms (for example, real GDP grew 4% last quarter). Now, we turn our attention to another important measure of the economy. We want to measure how the cost of living changes over time. The main intuition here is that, over time, peoples’ incomes and the prices of goods and services increase. 30 years ago an ice cream sundae cost $1 and a typical economics professor earned $35,000.
