To understand how the education levels effect on earnings and rates of return to education, Ben Tre province in the Mekong Delta is chosen as a case study in this study. Data of 143 workers, aged from 15 to 60 years and having earnings are draw from Vietnam household living standard survey (VHLSS) 2006. The theory of human capital and Mincer earnings functions (1974) are employed in this research. Estimation results show that among explanatory variables such as schooling years, education levels, working hours, cultivated land size, gender, and sector have significant effects to earnings.
One more schooling year helps to increase earnings of workers by 5. Person, work in public sector, obtain higher education level and earnings than those works in private sector. Similarly, higher education and earnings are found for male workers than those of female workers. The fact that increases in working hours has positive effects to earning are a reasonable result.
Meanwhile, region and experience of workers have no significant effects to earnings. From the results of this research, some policies will be suggested to increase individual income through the improvement of individual education factors. Rates of return to education are not linearly with education levels. Highest rate of return is found for secondary school level.
Findings from this research confirm the benefit of education on earnings of workers, and rates of returns are not the same for levels of education, which are similar to research results of their studies. iii TIEU LUAN MOI download : skknchat@gmail.com -------,---- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - CONTENTS Page CERTIFICATION. ix LIST OF TABLES.

PROBLEM STATEMENT Living standard level is different from everywhere, Knight and Sabot (1990) stated that there was an inequality of income among households. In the rural areas, there is a lot of households which are living in poor condition due to low income. Vietnam is considered as one of the poor countries in the world.
The average income level is just about one dollar per head per day, and 20.0 percent of population living below poverty line (GSO, 2006). Therefore, the improvement of income is very important, especially for poor households to escape from present bad situation. The benefits of formal education have been known for a long time. Mincer (1974) showed that the benefits of formal education on individual earnings.
Lucas (1988) proved that benefits of education within a village known as the side effect. Moreover, education can benefit the entire country at national level. In short, education can benefit people from individual, household, local community, and country level. The positive relationship between education of a worker and his/her earnings and productivity has been witnessed in many countries (Schultz, 1988).
In addition, educational attainment and earnings inequality still prevails between men and women, rural and urban areas, and between the public and private sectors as well. These issues require further understanding and examine the linkage between education and earnings. Ben Tre province, located at the downstream of the Mekong River's basin, is known for agriculture-based society. This is one of the smallest inland area 2,315 squared kilometres among Mekong Delta region, but its population density ranks at the fourth place.
GDP growth rate in 2001-2005 is of 9. The income per capita is of 4.5 million in 2006 and 950 USD in 2010. In terms of education level, the literacy ratio of Ben Tre province's population is of TIEU LUAN MOI download : skknchat@gmail. The labor force accounts for 72.73 percent of the population (BSO, 2006).
However, the quality of this labor force is poor in terms of education and in terms of working skills. In 2006, 60 percent of the labor force is unskilled labor. Only 30 percent of the workers get vocational certificates (BSO, 2006). Although there is high literacy (97.4 percent), the general education level of population is still at low rate (52 percent) household heads under primary school.
In addition, the numbers of poor households accounted for 18 percent of the total households in Ben Tre province and reduce to less than 10 percent in 2010 (BSO, 2006). The opening of Rach Mieu's bridge in 2008, connecting Ben Tre province to other provinces, and socio-economic conditions of human capital, and comparative advantage to reduce the poverty rate and improve income of its people in Ben Tre province. Thus, how to raise people's income is a big concern. While the benefit of education has been generally demonstrated, the benefit of education to income is not clearly explored.
This socio-economic context inspired researcher to conduct a study on the effects of education on earnings in Ben Tre province. OBJECTIVES OF THE THESIS The purpose of this study is to analyze the effects of education on earnings of workers, and to examine the rates of return to education levels. Especially, it also takes into account the differences in returns to education by controlling wage differences, geographical regions, economic sectors, and gender in order to draw out policy implication for education development in Ben Tre province. To fulfill these objectives, rates of return to education are used as an instrument to measure educational effects on earnings.
It is commonly recognized that higher education is tantamount to higher earnings, or in another words earnings positively relate to education.
