socialist-oriented market economy provide both challenges and opportunities for the people in Vietnam Under Doi Moi Renovations, the opening up of Viet Nam to a competitive global marketplace, with rapid changes in information technologies, capital flows, mass media and culture The transition to a market economy in Viet Nam involved a drastic modification of young men and women's transition from school-to-work Today, many youth enter the labour market resulting in labour is a critical aspect of Vietnam's development strategy in overcoming persistent poverty and enhancing further economic growth as set out in a number of documents, such as the country's ten year national strategy for socio-economic development (200 1-2010) with its second five year socioeconomic development plan (2006-2010) One of main objectives for Vietnam is to further strengthen its economy and prepare the country for further integration into the world community that need numerous skilled employments Meanwhile, education has played an important role in preparing knowledge for an employment prior to joining labour market The linkages between the education and training system and the labour market have to be strengthened to close the gap between the skills in demand and the skills offered on the labour market It is said that a person's successes in seeking a job after quitting school is remarkable affected by the period he have stayed at school As a result, individuals with high levels of education are able to find work more easily, to command higher wages within a given occupation, and also to improve their chances of upward occupational mobility Harmon and Walker (1995) suggest that educational attainment is the main observed determinant of occupational status, which directly influences earnings Vietnam has been viewed as labour endowment but low productivity because of unskilled or semi-skilled employment Consequently, being employment or unemployment is not hirge distance For example, if an employment gets higher education, he enables to adapt easily with changes of technology in a firm, so that he has more opportunities to be hired again Additionally, Hamilton et al (2000) proves that workers who receiving more training will receive higher income because their training costs are lower than others without or less training Adversely, he will become unemployment if his company makes changes in technology By finding contribution of education on employment's wage, we can stress the impact of schooling to individual at initial stages On other hand, children are affected by their family background Father, mother and siblings create an environment that help a member better, otherwise adversely effect by their interactions Meghir (2005) finds that one of factors is parents' education Practically, parent with good education and pay more time for children can be instructor that encourage them to better study and confident in choosing a work If we combine two ideas above, we can find an interesting relationship between wage and family background of a person after quitting school Within this framework, the purpose is to determine the extent to which parents' schooling outcomes feed through into children's schooling The determinants effect on wage of an employee is obtained by running ordinary least squared model I have utilized data of VHLSS 2006 and 2008 for my thesis The next section will introduce previous relevant empirical studies Section III will present about Vietnam labour market Section IV explores the model and introduces the data in Sections V The empirical findings are reported in Section VI with several sensitivity tests are undertaken, and Section VII provides concluding comments 1.1 Research goals and objectives CHAPTER CONCLUSION 7.1 Conclusion This study aims at examining determinants of employee's wage for the Vietnam labour market on the basic of Vietnamese Household Living Standards Survey The estimation results are basically consistent with the findings of empirical studies and expectation The only difference is Duncan index represented for household's head occupation This is explained by lower educational attainment and proportion of manual jobs of parents The improvements of education and occupation have lead to positive effects recent years such as in 2008 Practically, living standards have improved resulting in they themselves take care of children as well as interest in their children' education In term of family background, number of siblings negative affects wages But in some case this variable is insignificant One of findings is worker lives in the South East and urban receiving higher wages The results emphasize the real situation that people have tendency to favor living in city and urban areas Age and ethnicity of workers are significant and positively correlated with wage while married status and ethnicity are recognized insignificant in 2006 The education attainment of worker is positive increase to wage It is the key factor effect on wage The improving each level in five categories confirms wage increasing during investigated period from 2006 to 2008 The regression results of the study shows that the goodness-of-fit of the model is around 20% It means there are 20% of the total variance in wage is explained by all independent variables 7.2 Policy implications Educational attainment of workers is recognized the strongest factor effect wage The finding shows the important of education combination with worker's skills encourage the vocational training for all workers Therefore, some policy implications are suggested below 41 Firstly, to support and push improvement educational attainment of workers Short, medium, or long term training courses would help employee equip necessary knowledge prior to working through encouraging private sectors as well as enterprises set up training center, university create more seats for students Each year, Vietnam's workforce increases 1,484,200 people (from 2000-2009, MOLISA) which young labour accounts for around one third Meanwhile, technical and professional workers have been become competitive advantages instead of cheap unskilled workers Therefore, if the number of workforce getting vocational training increases, labour market will increase more skilled employees that helps improve the advantages of labour force This implication can be deployed as Vietnamese's literacy rate is over 90% and 64.46% workforce graduated High school including 38.64% Lower secondary graduation As a result, labour endowment really proves its advantages in attracting investments On other side, well-equipped knowledge prior to entering labour market will help employees quickly get used to jobs as well as create more chances to find out works after leaving schools In long time, it leads to rising in group of wages and salaries worker, and decreasing in group of vulnerable worker which is considered as a source of widespread poverty Secondly, to encourage the joining of firms in vocational training The gap between knowledge teaching in schools and requested knowledge in working is big problem because training does not meet practical needs Enterprises often claim that they have to re-train for employees after recruitment And it costs both time and funds not only for employers but also for employees If universities associate with employers in construction teaching programs, students will be taught practical awareness that help them easily begin new after leaving schools Therefore, the cooperation will narrow down the gap as removing the barriers which have existed for a long time ago leading to cutting costs Furthermore, more classes are opened for workers and students that give them more chances to successfully seek works And the cooperation will contribute to the socialism policy in education of the J Government by utilizing funds from enterprises 42 - The mentioned suggestions aim to improvement education of employees They are initial help workers inore opportunities to find out works as well as improve the labour endowment advantage Next, they can affect the ratio of wages and salaries group and vulnerable group in employed workers leading to preventing widespread poverty 7.3 Limitations In my thesis, the Adjusted R is over 0.2 Thus, hourly wage is explained approximately 20% by independent variables in the mode That is caused by the restrictions of data set which are mentioned in chapter as well as the restriction of number of variables Next, I have selected between mother's education and father's education, which one is higher as proxy variable for parents' education because there is not full data of both mother and father for each employee because of lack of spouse's information in cases such as widow, widower or divorce Therefore, I cannot independent test effect of education of mother and father on employee's wage Thirdly, occupation of household's head is scored as Duncan (1961) with modification in selection works for each group according to VHLSS's occupation codes That index was originally constructed by the US data, so it would make differences in implication, even though there were adjustments The limitations may be a chance for further research 43 REFERENCES Ashenfelter, Orley and Zimmerman J.David, 1997

which is paid in cash or in kind or by mutual help (2) self-employment to earn income for oneself (3) activities of production, business and service for one's own family and no wage or salary is received (MOLISA) Employed: a person who performed some work for at least one hour during the specified reference period for a wage or salary (paid employment) or for profit or family gain (selfemployment and contributing family work) A person is also considered employed if he/she has a job, but was temporarily not at work during the reference period The employed are all persons aged 15 and over in the labour force and those who are defined as being involved in one or more of the above-mentioned forms of employment in the last seven days Employed youth refer to those aged 15-24 who are involved in employment in the labour force (MOLISA) Job: a paid position of regular employment According to the standard definition, therefore, only wage and salaried workers could have a "job" Common usage, however, has extended the concept to encompass any work-related task, which means that any employed person, whether a paid employee, self-employed or unpaid family worker, could qualify as "with a job" (ILO) Labour force: Labour force or economically-active population includes all people who are of the age of 15 or above and employed, and those who are not employed but able to work and have a demand for a job In this regard, those outside the labour force refer to the economically-inactive population who include all people aged 15 or above but who are excluded from the employed component and unemployed Labour market: the virtual (non-tangible) arena where workers compete for jobs and employers compete for workers Analysts use labour market information, including statistics such as the employment-to-population ratio, the unemployment rate, etc., to make assessments of how well the labour market functions and how and/or why the supply of labour and the demand for labour not meet at perfect equilibrium (ILO) 49 Own-account workers: persons who are self-employed, with no employees working for \ them Unemployed: a person who, during the specified short reference period, was (a) without work, (b) currently available for work, and (c) actively seeking work (that is, using at least one of a number of methods to obtain a job) A person is also considered unemployed if he/she is not currently working, but has made arrangements to take up paid or self-employment at a date subsequent to the reference period (ILO) Unemployment: a measure of the total number of unemployed persons Unpaid family worker (also called contributing family worker): a person working in the family business without pay The business is owned or operated by a family member, who is an own-account worker: (ILO) Vulnerable employment: for purposes of this report, the sum of own-account workers and contributing family workers (unpaid family workers) (ILO) Work: as a verb, a general term meaning to engage in "economic activity" or, equivalently, to supply labour as input in the production of goods and services As a noun "work" has come to be used interchangeably with "job" and "employment" for example, a person who supplies labour might say he/she "has work" or "has a job" or even "has employment" (ILO) Working age people: People at the working age outside the labour force include all people who are of the working age (men aged from 15 to 60 and women from 15 to 55) and excluded from the employed component and unemployed 50 ' Table Al: Construction of Duncan index
