Difference between consumption and investment

CPI and GDP deflator generally seem to be the same thing but they have difference between consumption and investment few key differences. Both are used to determine price inflation and reflect the current economic state of a particular nation. GDP Deflator takes into account goods that are produced domestically.

It does not bother with imported goods and it reflects the prices of all the commodities, services included. The GDP deflator is calculated quarterly and it weights may change per calculation. GDP is an abbreviation of Gross Domestic Product which is the overall value of all final goods and services made within the borders of a country in specified period. GDP has two types the: Nominal GDP and the Real GDP. The ratio of the two values is the GDP deflator.

Essentially, the GDP deflator compares the price level in the current year to level in the base year. There are so many price indices out there and GDP is unlike some of them that are based on a predetermined basket of goods and services. In the GDP deflator, the so-called basket in a year is weighted by the market value of all the consumption of each good therefore it is allowed to change with people’s investment and expenditure patterns since people do respond to varying prices. CPI, which is short for Consumer Price Index, indicates the prices of a representative basket of commodities procured by the consumers. It uses a fixed basket of goods and services and is a widely used measure of the cost of living faced by consumers of a nation.

Like the GDP deflator, it also compares prices of the current period to a base period. CPI tends to consider insignificant goods, even the outdated ones that are not really purchased by the consumers anymore. Nevertheless, they are still considered for pricing in the fixed basket. As you can see, GDP deflator is not identical with the CPI but provides an alternative to each other as a measure of inflation. Over long periods of time, both provide similar numbers, but they can diverge in shorter periods.

The GDP deflator measures a changing basket of commodities while CPI always indicates the price of a fixed representative basket. GDP deflator frequently changes weights while CPI is revised very infrequently. CPI will consider imported goods because they are still considered as consumer goods while GDP deflator will only contain prices of domestic goods. Difference Between CPI and GDP Deflator. This article would be more helpful if it said who calculates the deflator.

I think that CPI is more appropriate to observe the change in inflation because changing basket could have an influence on the calculations, but I am not sure about it.

You agree that we have no liability for any damages. A seed is defined as an embryonic plant covered in a seed coat, often containing some food. It is formed from the ripened ovule of plants after fertilization. Seed formation completes the reproduction cycle in seed plants, which begins with the growth of flowers and pollination. The embryo grows from the zygote while the seed coat grows from the ovule rind.

A grain is a small edible fruit, usually hard on the outside, harvested from grassy crops. Grains basically grow in a cluster on atop the mature plant and they include wheat, oats, rice and barley. Because grains are generally grown on a large scale, they are considered staple crops and they are the number one energy providers worldwide. Technically speaking, we can refer to a seed as an ovule containing an embryo within, while a grain is a fusion of the seed coat and the fruit.

In some grains like peanut, the shell can be separated from the fruit to reveal the seed. However, in other grains like corn, the seed coat and fruit tissue cannot be separated. A seed typically has three basic parts which are the embryo, seed coat and the endosperm. Obviously, the embryo is the most important part because it is its cells that eventually differentiate and grow into the various tissues that constitute the plant eventually. Grains provide food mainly from the fruit part, for instance, food from wheat grain is derived from the ground fruit, which is a part of the grain. In crops like millet, it is actually the seed that has properties very similar to those of the fruit part of the grains, and that is why it is handled as a grain in culinary terms. These could be ground to get flour which can be very similar to the one taken from typical grains in culinary terms.
