Lesson 17 NATIONAL-INCOME ACCOUNTING

aggregate economic activity, particularly national income and its components. The

measurement of aggregate economic activity by national-income accounting serves two basic functions. First, it enables us to identify economic problems. The second function of national-income accounting is to provide an objective basis for evaluating policy.
National-income accounts help us not only to measure the economy but also to understand how it functions-Gross national product (GNP) is the total market value of all final goods and services produced in a given time period.
GNP per capita is total population: average GNP. GNP per capita relates the total value of annual output to the number of people who share that output; it refers to the average GNP per person.
Even when we focus on domestic market activity we encounter problems in calculating GNP. A very basic problem arises from the fact the production of output typically involves a series of distinct stages. Consider the production of bread, for example. For bread to reach the supermarket, the farmer must grow some wheat, the miller must convert it to flour, and the baker must make bread with it.We must focus on the value of final goods and services and exclude intermediate goods from our calculation.
Intermediate goods are goods or services purchased for use as input in the production of final goods or services. Nominal GNP is the value of final output produced in a given period, measured in the prices of that period (current prices).

from increases in their prices, we must construct a measure

of GNP that takes into account price level changes. We do so by distinguishing between real GNP and nominal GNP. Nominal GNP is the value of final output measured in that year's price?, whereas calculating real GNP, we value goods and services at constant prices.
Inflation is an increase in the average level of prices of goods and services.
Production possibilities are the alternative combinations of final goods and services that could be produced in a given time period with all available resources and technology.
Depreciation is the consumption of capital in the production process; the wearing out of plant and equipment. This calculation leaves us with yet another measure of output; nef national product (NNP). This is the amount of output we could consume without reducing our stock of capital.
The distinction between GNP and NNP is thus mirrored in a distinction between gross investment and net investment. Gross investment is positive as long as some new plants and equipment are being produced. But our stock of capital — our total collection of plant and equipment — will not grow unless gross investment exceeds depreciation. That is, the flow of new capital must exceed depreciation, or our stock of capital will decline. Whenever gross investment exceeds depreciation, net investment is positive.
Exports are goods and services sold to foreign buyers.
Imports are goods and services purchased from foreign countries.
International trade is not a one-way street. While we export some of our own output, we also import goods and services from other countries. Whatever their use, imports represent purchases of goods and services that were not produced in their country.
The GNP accounts subtract imports from exports. The difference represents net exports.

вартість — це збільшення ринкової вартості продукції, яке відбувається на кожній стадії виробничого процесу.
Як зміни цін впливатимуть цього року на валовий національний продукт?
Для того щоб обчислити реальний валовий національний продукт, необхідно оці¬нити товари та послуги за постійними цінами.
Для того щоб підтримати наші виробничі можливості, ми повинні повернути капітал, який ми витрачаємо.
Щоразу, коли валові капіталовкладення перевищують амортизацію, чисті інвестиції є позитивними.
Виробничі можливості залежать від кількості землі, праці, капіталу та наших знань, як використати нову технологію.

2. If gross investment is not large enough to replace the capital that depreciates in a particular year, is investment greater or less than zero? What happens to our production possibilities?
