Theory and literature review
Theory
Education and income are interrelated to each other and it can be observed that income is
heavily affected by education level that individual have. Education determine qualification and
by considering same salary is given to the individuals (The connection between education,
income inequality and unemployment, 2017). Some times busienss firms also consider location
because in some locations there are large number of educational institutions which deliever high
quality of education. Hence, employers have special attention towards candidates that take
education from location or city that is known for well named colleges and also pay high salary to
them.
Literature review
According to Noble and et.al., (2015) there are number of factors that determine income
level of individual and education is one of them. Usually, it is observed that if one have high
level of education then employers think that it is well qualified person and offer high amount of
salary to it. On this basis it can be said that education factor play vital role in determining income
level of an individual. Apart from this, country of education is the another factor that have heavy
influence on the determination of income level. Country of education basically means nation
from which one take education or states of the nation from which education is taken by an
individual. It is observed that state of the nation from which education is taken is widely
considered by the employers while giving salary to individuals. This is because there are specific
locations or states where ther are number of highly technical education institutes and due to this
reason employers think that individual coming from that areas are well qualified and good
amount of salary is offered to them. On this basis, it can be said that education and location from
which education taken both have impact on income level of individuals. Thus, one must with
due care must select education institute for taking education so that good amount of earning can
be made at job.
Contrary to this Hiza and et.al., (2013) state that income level and country of education
does not have any relationship. Business firms usually give importance to the knowledge level
that individual have in respect to its domain. College from which an individual do study does not
have any sort of relationship with its income level. If an individual completed its study from well
known college then it does not mean that it also possess good knowledge. It is possible that

individual completed its study from college that is now so prestigious but it may have good
knowledge or vice verse. Due to this reason firms does not make any difference among
candidates in terms of salary on basis of education from specific area. Thus, it is the knowledge
level which is respected by employers and accoridingly salary is given to employees.
According to Chevalier and et.al., (2013) gender is the factor that is considered by most
of employees while deciding salary of employees. It is observed that low amount of salary is
given to women then men. This gender descrimination is observed across all sorts of firms and
more commonly in European nations. Woemes salary is significently lower then same of male
and it can be said that this is wrong thing that is happeneing across globe.
Contrary to this RodrÃguez-Pose and Tselios, (2010) state that usually it is observed that
womens are not involved in highly technical work and this is the reason due to which low salary
is given to them irrespective of geographic location from which they start their study and type of
qualification they have in respect to performance of the job. Thus, on this ground salary
descrimination can not be considered completely wrong.

analysis is another method that is used to analyze relationship between dependent and
independent variables. It can be said that by using relevant statistics analysis will be done in
proper manner.
Analytical strategy and model specification
As part of analytical strategy first of all for specific variables descriptive statistics will be
run. Apart from this, regression analysis will be run and under this model will be developed
under which there will be one independent and other will be dependent variable. As part of
model specification it is clear that for first objective independent variable will be country of
education and dependent variable will be income level. On other hand, for second objective there
will be same dependent variable and two independent variable which are country of education
and gender.
