National Income Analysis: GDP, GNP, and Economic Freedom Study

This assignment analyzes national income using both the expenditure and income approaches. Part 1 focuses on calculating GDP using the expenditure approach, comparing nominal and real GDP, and analyzing the components of GDP such as personal consumption, investment, net exports, and government spending. It also explores the differences between nominal and real GDP and the significance of each component. Part 2 shifts to the income approach, examining GDP, GNP, net national product, national income, and personal income. It explains the relationships between these measures and analyzes their components, with a focus on the categories that constitute national income. Part 3 compares countries based on per capita income, ranking them and discussing the significance of GDP and GDP per capita as indicators of economic performance. Part 4 examines overall economic freedom scores and various economic freedoms by country, providing insights into factors influencing economic performance and comparing economic indicators across different nations. The assignment uses data from the Bureau of Economic Analysis and the Heritage Foundation, providing a comprehensive overview of national income analysis.

Why nominal GDP is greater than real GDP
Heretofore, the nominal GDP of the last quarter of 2018 is $20865.1 billion whereas the
real GDP is 18,765.3. Therefore, the nominal GDP exceeds the real GDP by $2099.8 billion.
According to Mankiw (2015), the real GDP always has a higher value than the real GDP because
it carries the effect of inflation. Given that inflation is positive, the value of the real GDP is
always lower than that of the nominal GDP.
Category by proportion of GDP
Analyzing the tables given above, the personal expenditure category constitutes the
highest proportion of both real and nominal GDP at 69.45% and 68% respectively. The
implication of this result points out that any given nation’s GDP majorly consists of personal
consumption expenditure. The net exports and imports category form the least part of both real
and nominal GDP having contributed deficits of 5.09% and 3.16% in that order.
The Gross Private Domestic Investment
This is an estimate of the proportion of capital that investors put into the purchase of
fresh inventory in the economy. It involves purchase of physical assets and stocks. Krugman and
Wells (2013) note that such investments do not factor in the purchase of financial assets such as
bonds.
Why the net export component is negative
Notably, from the two tables above, the percentage contribution of the net exports is
negative. The negative figure is realized because the amount of imports into the US during the
period of analysis was greater than the exports in both real and nominal terms.

NATIONAL INCOME 6
National defense
From table 3., national defense expenditure contributed $799.6 billion in nominal terms
and 761.2 in real terms to the government consumption expenditure and gross investment. If
converted into percentage, in nominal terms it contributed 799. 6
3,569.4 × 100 %=22.4 % and
761 ..1
3,188.7 ×100 %=2 3.87 % in real terms as a percentage of government consumption expenditure
and gross investment.
From the foregoing analysis, three crucial lessons were learnt. That, the real GDP is
always less than the nominal GDP since its market prices have been adjusted of inflation of
which the nominal GDP is not. Further, the net exports can be sometimes negatively affecting
the GDP. That happens when the imports are greater than exports yielding a negative figure for
net exports. Finally, the computation of GDP using the expenditure approach assumes that the
total money spent on various products within the economy ought to be equal to income from the
goods and services and that the personal consumption expenditure forms the major part of the
GDP.

GDP and GNP
When considered, GDP and GNP are both measures of economic output of a country
with specific periods. However, GNP values the production that takes place within a country’s
borders while GDP takes the value of production by citizens of a given country whether within
or without the country with adjustments for net production by foreigners.
Further analysis of the data provided shows that the GDP apparently fluctuates.
Sometimes it increases whereas it decreases in some other instances. This phenomenon is
explained by the occurrence of the business cycle as explained by Miller (2012). It falls when the
economy is in recession and rises when the economy booms.
Some adjustments on GDP to find GNP

NATIONAL INCOME 8
Gross National Product is obtained by introducing the net-income to and from abroad to
the GDP. That way income earned by foreigners in given country is subtracted while that earned
by citizens of that country who are overseas is added to the aggregate income of the economy.
NI and NDP
National income is obtained by adding all earnings attributed to factors of production. For
accountants to arrive at such a figure, they must subtract business tax, transfer payments and any
firm income corrections that do not increase or decrease that national income. It differs from net
domestic product (NDP) because unlike NI, NDP includes all the net factor income from abroad.
National Income (NI) and GNP
Overall, GNP shows to be lower than the national income because for one to arrive at the
GNP, they must deduct capital consumption and other statistical discrepancies. However, in
practice, they are the same except for the discrepancies for which adjustments have to be made.
Category by composition of National Income
From analysis done in this paper, the category of employee compensation constitutes the
major part of national income. The category includes the payment to workers for their services
during a specified period of production.
Significance and Reflection on data analyzed
In practice, GNP is a better measure of economic performance because it includes all incomes
earned by the citizens of a given country whether in or out of the country. Further, GNP exposes
those citizens who repatriate property and income to countries other than where they produce or
earn their income. GNP, as much as GDP has had criticism reveled against them notwithstanding

NATIONAL INCOME 9
their performance in exposing repatriation leading to economists resorting to Gross National
Income that they deem more accurate than both GDP and GNP. Other measures that have been
used in some other circumstances include the Gross National happiness and Green GDP to factor
in the effects of production activities on the environment. The world bank is one organization
that has consistently used the GNI in ranking countries according to their economic performance
in three tiers- the low, middle- and high-income earning countries. It is also noteworthy that the
newfound measure in GNI, does not give a summary of development statistics to the economists
and therefore its undoing.
Further, it is important to note that aggregating the personal incomes of all individuals in the
economy may essentially add up to the figure of net national income as such method excludes
the transfer payments such as old age pay and social security funds. Finally, during the lessons of
computing national income using the income approach, it was noted that the overall income
earned by each factor of production may be added to give a common figure that is taken as the
national output.

followed by Switzerland and the USA in that order. China has the least GDP per capita while
Mexico is second last with a GDP per capita of $ 8910.

From the two rankings above, it is noticeable that the ranking for all the countries differ.
Some countries rank higher when GDP is used but they fall to lower rankings when the GDP per
capita measure is used. Contrary, others such as Luxembourg rank lowly when they are
compared with the rest on the basis of GDP but they top the list when they are ranked depending
on GDP per capita. The reason for this is the difference in population. Countries with higher
population will record lower GDP per capita unless their GDP is extremely high, In this case,
Luxembourg has a lower population when compared with the rest of the countries hence the
higher GDP per capita.
Significance of data on GDP
The determination of economic performance of an economy is anchored in the
computation of national income statistics. According to a Mankiw (2015), the data is useful in
analyzing the performance of a given country across periods and for comparison against the
performance of other countries from the same or other regions of the world (Romer, 2012).
However, under such circumstances, the GDP of all the countries must be first be expressed in a
common currency. On other occasions, the data is useful in creating development plans for the
concerned countries. Also, it can be reckoned that data on the GDP and GDP per capita can be
