It is that high school in Korea have been developed so far rather quantitatively than qualitatively. Changes an expression in a differnt way, the number of high school students are increased to have estimated about 1.0% annually from 1975 to 1995, and the tuition & fees of high school education has also increased without any qualitative improvements accompanied. In particularly, the high school tuition & fees are estimated to have increased about 13.0% every year from 1975 to 1995. This means that the high school tuition & fees which has been imposed on the students household fall heavily on the parents of students in Korea. Meanwhile the high school graduates has been increased about 4.6% every year from 1975 to 1995, and on the contrary the jobless high school graduates was estimated to have decreased about 3.0% annually within a given period of the same time. But there is an unemployment problem of the high school graduates because it is ture that an increasing rate of the graduate students has been exceed a decreasing rate of the jobless high school graduates. In this regard, the present study valuates the tuition & fees that was imposed on the households of high school students with a view to seeming if the amount of the high school tuition & fees are reasonable. First, the real tuition & fees of high school correlated with the real wages of the high school graduates in the higher level, the correlate parameter was estimated 0.94 per year from 1978 to 1993. Second, this valuation adops S. Bowles'model and A. Okun'Law. And then, the result of the analysis shows that the efficiency of the high school tuition & fees per month was valuated the average parameter of 0.43 per year from 1978 to 1993. Third, the high school tuition & fees had positively affected about 0.1% per year the economical production from 1978 to 1992 and efficidency of the high school tuition & fees are estimated to have been improvemented about 43.3% per year annually within the same period. But the efficiency of the high school tuition & fees has been negative alt but one year, and so it is quite possible as we have guessed that the high school tuition & fees has negatively effected on the economical production so far.

First, the marginal economic gains as influenced by private scooling expenditure is about 4.04 for farm households and 4.66 for non-farm households. compareing the incoms of farm households with those of non-farm households, we can see that non-farm households incoms were 4.82% lower Second, with respect to the internal rate of returns classified by each family, the difference is seen to be 0.489 between farm households and non-farm households; non-farm households show 104.89% compared with 100% farm households. The burden of private schooling expenditure, if we compare the income of non-farm households with that of farm households, is more toward non-farm households that to farm households by 5.62% Third, with respect to the demand for education according to the farm and non-farm households, when income and private schooling expenditure ar eanalyzed simultaneously, the elasticity of demand for education is show to be 0.1934 fo farm households, 0.1308 for non-farm househods. On the basis of the present analysis, the increase of demand for eucation in the future will be higher in the farm households than non-farm households and private shooling expenditures of farm households will alsoincrease more that of non-farm households.

Specially the real wages of the graduates correlated with the various schoooing levels accompanied with the tuition & fees of schooling in Korea. And so, in Korea human capital which was molding with the tuition & fees had been centerater on the analysis of economic development acording with earnnings. The adoped means of the analysis was the equation of G. S. Becker and their fellow's model to estimate above the economical problem of the tuition & fees from 1975 to 1995 in this study The result of the economical problem was analyzed as the below. First, the under graduates of the middle school contribute to the economic development from 11% to 20% degree and the high school graduates contribute to the economic development from 18% to 20% degree in the same time and conditions. The contribution of the college graduates to the economic development was estimated from 23% to 27% degree and the graduates of the university was estimated from 34% to 43% degree. Second, the economical contribution per year was analyzed about 16% degree in the under graduates of the middle school and the high school graduates was analyzed about 20% degree. Besides, the economical contribution per year each was analyzed about 25% degree on the college graduates, about 40$ degree on the university graduates. Third, a variation of the economic contribution was negative effect in the graduates of the college and university levels. Conversely, it was positive in the graduates of the middle and high school levels. It's was about 2.6% degree, about 0.6% degree respectively. Fourth, and so it is quite possible that we have guessed as the college and university tuition & fees not influenced on the economic development positively but the middle and high school tuition & fees influenced on the economic development positively in Korea.
