8. What is meant by the

Gross National Product(GNP) of a country? Describe the methods and difficul- ties of measuring it.

Gross National Product is defined as the total value of goods and services produced annually in the nation.. It is a measurem ment of the economic worth of nroduction tq society. Usually, it is the sum of the market values of the final goods produced by the mation's resources during. the year in question. Notice that GNP is a flow; it is an amount of product

It ion per unit of time. refers to those outputs which are: created in the

but not those which year, have long existed in the country before the year in questione

Methods of measuring Gross National Product

There are at least two ways of measuring. GNP.

First, we can sum un the value of all woods and services produced annually in the nation. The value of each category of goods is given by quantity multi- folied by its market price. TAIL outnut in the nation

flows to one of the follow- ing four uses: consumption, investment, government nur- chases, and net exnorts. Their sun is therefore, lequal to GMP

of the incomes earned in the production of GMP: rent wapes, profits, interest, etc. The aum 1a-ca14ed Gross National Income (G1). Since the flow of, product- ion generates the flow of.

, gross national

product is always matched.

by gross national income.

By this method, we can indirectly obtain the value of GNP.

Difficulties of measuring Gross National Product

(1)GNP and changes in prices:

GNP is usually measur- ed in terms of current dollar prices. When prices change, the values assigned to the various goods and services in GNP also :chenge Thus, in an inflation the value of GNP increases

(4)Foreign payments:

Income may come from

abroad, or payments may be made to foreign countries for some reasons. To some extent payments and receipt will offset one another.

·The net value should be included in the domestic national nroduct.

(5)To avoid double countingal transfer payments made by government to the bublic should be carefully counted

Exercise:

outout, we 'must ad dist for the effect of changes in prices, so that any increa. se in GNP reflects a real rise in outnut, not the

rise in prices. For exam- ple, both 1956 and 1976 outputs can be compared if both of them are expressed in terms of constant price dollars: both 1956 and 1976 outputs are multiplied by prices of a single year--- which may be 1956, 1976, or some other. In nractice, it is difficult to estimate the changes in prices with- in a period of years.

(2)The Measurement of GND does not include the value of services that are not exchanged in formal markets For example, the cooking services of a wife are not measured as part of nation al product, yet the same services bought in a restaurant are.

(3)The definition of "final goode" is not per- fect. For example, should the gasoline be regarded as a final product or as an intermediate good. Problem arises in drawing a distin- ct line between final goods and intermediate foods.

As

a result, national prodcut tends to include some items it should not and exclude others it should include.

BIOLOGY (8)

Unit THREE, Water and organisms

Water is an essential component of every cell. It is the medium in which various substances are dissolved and all physiot Logical reactions occur. It also takes a role in the body heat distribution and regulation.

Any excessive gain or losa, of water will disturb the normal metabolism of organ- isma. Terrestrial organisms have to face the problem of water loss while aquatic animals have to prevent the osmotic inflow of excess water.

We should have a clear concept on the following termat

1.Osmosis: The passage of solvent molecules from the lesser to the greater con- centration of solute when two solutions are separated by a membrane which select- ively prevent the passage of solute molecules but is

permeable to the solvent."

In living systems, the

solvent molecules are water. Cell membrane is the select- ive membrane.

2.Turgor pressure: An in- ternal pressure generated as water enters a plant cell by osmosis and the cytoplasm is pressed again- at the cell wall. It pre- vents the entrance of any additional water.
