Human Capital: Introduction, Economical Evolution, Cost of Human being Upper-case letter
1. Introduction to Human Capital:
Capital embodied in human beings in the course of educational activity and health which make them more productive is called human being capital.
Concrete capital human resources or human majuscule plays a significant role in determining economical evolution. More than pedagogy makes the homo beings more productive through enhancing their skills, abilities, knowledge and better health enables them not only to participate in the production process simply increment their capabilities to produce more than.
Thus educational activity and health tin add to the value of production in the economy and besides to the incomes of the persons who take been educated and fabricated healthy.
The human upper-case letter is embodied in human being beings. Man capital comprises the didactics, knowledge, the skills, better health and the capacities of all people in the society to undertake production.
On the other mitt, the concrete capital letter consists of produced ways of production such as machines that are used in producing other goods. Economical evolution calls for both forms of capital accumulation. And both forms of upper-case letter call for investment.
Investment in human being capital letter has therefore been chosen ‘investment in homo’. Education plays a crucial role in the ability of a country to absorb modern technology and to generate the capacity for self-sustained growth and evolution. Health is besides essential for increase in productivity of labour and, therefore, not simply raises the private incomes only too contributes to the growth of GDP.
Thus, Todaro and Smith write, “Both wellness and pedagogy tin also be seen as vital components of growth and development equally inputs to the amass production office. Their role as both inputs and output gives health and teaching their fundamental importance in economic development.”
Till recently economists accept been considering physical capital every bit the nigh important factor determining economic growth and have been recommending that charge per unit of physical uppercase formation in developing countries must be increased to accelerate the process of economical growth and enhance the living standards of the people. But in the last three decades economical research has revealed the importance of education as a crucial factor in economic evolution. Pedagogy refers to the development of human skills and knowledge of the people or labour force.
Information technology is not simply the quantitative expansion of educational opportunities simply too the qualitative improvement of the type of education which is imparted to the labour forcefulness that holds the central to economic development.
Considering of its significant contribution to economic evolution, education has been chosen every bit human capital and expenditure on education of the people as investment in man or human capital.
Speaking of the importance of education or human capital, Prof. Harbison wrote “Human resources constitute the ultimate basis of production; human beings are the active agents who accumulate capital, exploit natural resource, build social, economical and political organisations, and behave forward national development. Clearly, a country which is unable to develop the skills and noesis of its people and to use them effectively in the national economy volition be unable to develop anything else.”
Human Capital and Economical Development:
Gross domestic product of a state depends on not just the amount of labour (i.e. work-hours) used for producing goods and services but also on its productivity. I of the important factors that determine productivity of worker is human uppercase, that is, education.
Every bit seen above, in the mod economic science the concept of capital is not confined to physical capital letter such as machines, tractors, capital equipment, etc. that raises productivity of labour but too includes what is chosen human capital.
By man uppercase we mean the skills and knowledge that workers acquire through education and preparation. This homo capital, that is, knowledge and skills, are accumulated past human being beings through instruction during the time they spend in primary and secondary schools and upward to graduation and post-graduation in colleges or universities.
Besides, specialised professional teaching such as engineering science, computer training, management pedagogy and others raises greatly the productivity of workers. Therefore, accumulation of human capital is generally chosen investment in people.
Only as a firm considers whether to invest in physical capital, individuals decide whether to invest in their ain human majuscule. When a house purchases machinery or other capital equipment to produce more than output and increases its future profits, individuals invest in educational activity or acquiring skills to raise their productivity and their time to come earnings. Investment in educational activity or acquiring new skills is called investment in human capital.
While usual models of labour supply presume that wage rate of individuals is stock-still, nonetheless through investment in human capital the individuals can raise their wages or earnings as investment in human being capital raises their productivity and it has been establish that in the United States rate of return on investment in secondary educational activity is x to thirteen per cent higher.
According to Prof. Amartya Sen, the improvement in the availability and quality of didactics results in higher level of functionings and capability of labour. He has shown in his works that for a state a depression level of education lowers the growth of Gross domestic product due to shortages of labour with advisable skills.
Besides, the empirical evidence bachelor suggests that countries which take invested more in pedagogy every bit measured by average years of schooling tend to feel, other things remaining constant, higher rate of growth. Furthermore, higher technical education helps to discover new inventions and innovations and thereby promote technological progress.
Human capital letter, though less tangible than physical capital, is like to it in many ways. First, like physical majuscule, accumulation of human being capital increases the ability of a country to produce more goods and services. Secondly, like physical capital, human being capital is a produced cistron of production.
Producing human capital requires investment in inputs such as pupil time, teachers, books and libraries, college buildings. Thirdly, like the concrete capital, the accumulation of human uppercase increases the productivity of workers and therefore causes their wages to rising. Fourthly, like the accumulation of physical capital, the accumulation of homo upper-case letter requires the sacrifice of some present consumption so as to have more consumption in future.
Price of Human Capital or of Acquiring Skills:
Man capital is congenital through acquiring more teaching or skills by spending more than time in schoolhouse, higher or university.
Thus, in spending more fourth dimension in acquiring more than didactics, 1 not but delays one’s entry into labour strength only also sacrifices income or wages which he could have earned by working during the time he spends for acquiring education. This is the opportunity cost of acquiring more education, skills and grades (i.due east., accumulating more human capital).
Just they spend time in acquiring more than human capital with the expectation that they would exist able to earn higher income or wages in the future as more teaching and higher skills heighten the productivity of the workers and therefore their wages.
Thus, the students, similar the people who save, confront a merchandise-off between less consumption today for more consumption in the time to come.
Thus, “spending more on education today (reducing consumption) raises hereafter income but each additional investment in instruction provides a smaller and smaller return”. It follows from above that, like concrete capital letter, expenditure on education also represents investment in upper-case letter which raises productivity in the future.
Too, investment in education is tied to specific homo existence and therefore it is called human upper-case letter. Thus, according to Mankiw, “Like all forms, uppercase education represents an expenditure of resource at i signal in fourth dimension to raise productivity in the futurity.
But unlike an investment in other forms of uppercase, investment in education is tied to a specific person and this linkage is what makes it human capital.” It is of import to note that workers endowed with higher education (i.e., more than human being capital) earn more income or wages than those having less education.
The differences in wages between those with more pedagogy and those with less teaching are quite big and have been increasing. For case “College graduates in the United States earn well-nigh twice every bit much as those workers who end their education with a loftier school diploma “.
Information technology may exist noted that this divergence in earnings between workers with more homo majuscule and those with less human being upper-case letter on an average tends to be even larger in developing countries where educated workers are in deficient supply.
That investment in education or human being capital has a cost can be easily illustrated. Economists are generally concerned with the opportunity cost of time spent in acquiring didactics or homo capital. If you are attending a grade acquiring teaching you cannot exist working simultaneously at a job yielding you some income.
Therefore, past attending computer classes you lot forgo some wages or earnings and hence some consumption which represents the cost of acquiring human capital.
How decision regarding more investment in education (human being capital letter) involves trade-off between consumption in the period of youth and consumption in subsequently working years is depicted in Fig. 9.1 through product possibility curve PP’. On the horizontal axis consumption in youth is measured, while consumption in afterwards working years (i.e., the period of machismo) is measured forth the vertical centrality.
Illustration of importance of investment in teaching and acquiring of human majuscule will bring out the importance of investment in human capital for raising earnings or living standards of the people. To keep things simple assume that just pick before our private is to invest in human being capital letter, that is, acquiring teaching and that he has no access at all to financial capital market place. Allow us assume that in the absence of any investment in human capital the individual is at bespeak A of the production possibility curve PP’.
In this situation a individual’s consumption is C
in the youth and C1
in the adulthood menstruum. Thus the situation at bespeak A represents what is called the endowment bespeak. At present suppose individual has the opportunities to attend classes of computer programming which is in fact a decision to brand investment in human being capital. Past attending the computer programming classes the individual would take to forgo some present consumption as he would not be working to earn income during that flow.
However, by acquiring the knowledge of computer programming he would be enhancing his productivity and earning capacity in the machismo menstruation. In fact, more than time he spends in attention conquering of estimator teaching, the higher will be his earnings in the adulthood menstruation.
However, this process of spending more than fourth dimension in getting education of reckoner programming is subject area to diminishing marginal returns. Each extra hour of estimator course raises his earning ability by successively smaller marginal corporeality. With these assumptions, the opportunities of the individual are reflected in product possibility curve PP’ in Fig. 9.i.
It volition be seen that this product possibility bend PP’ is concave to the origin and its curvature implies that each rupee reduction in consumption in the present period (that is, in youth) increases the future earnings in terms of consumption past successively smaller increments.
The product possibility curve PP’ drawn in Fig. 9.i is therefore often referred to as human being capital production function. Information technology shows how consumption in the present flow is forgone and transformed into human capital investment and higher earnings in the adult period.
To make up one’s mind how much time an private will spend on obtaining reckoner education or skill formation, that is, homo capital investment depends on his preference between present consumption and future consumption. In fact, human capital investment conclusion (i.east., investment in pedagogy or skill formation), requires trade-off betwixt lower consumption level in the nowadays in return for college earnings in the futurity.
To determine what level of homo capital investment the individual will choose, nosotros need to introduce indifference curves regarding individual’s preference between present consumption and time to come consumption. For this nosotros superimpose indifference curves upon his product possibility curve PP’ given in Fig. nine.i.
It will be seen from Fig. 9.1 that individual will choose signal E at which he volition exist consuming C’
in the present period of youth and C’ane
in the adulthood period. This means that his sacrifice of consumption in the menstruum of youth equal to C’– C
has led to a much larger increase in his consumption C’1-Ci
in the adulthood as a result of higher earnings fabricated possible by investment in human capital.
Render on Investment in Didactics:
The studies conducted past the World Bank show that economic returns on investment in education appears to exist higher than in alternative kinds of investment, especially in physical capital.
Further it has been found that rate of render to educational activity of all the three levels in developing countries is higher than in developed countries.
An important study based on bachelor statistical data of both developing and developed countries was made by George Psacharopoulos found that in the early 1990s private returns on master, secondary and higher education were college in developing countries of Sub-Saharan Africa, Asia and Latin America than the adult countries (Table nine.1).
For instance, private return to primary pedagogy was 41% in Sub-Saharan Africa, 39% in Asia, 26% in Latin America equally compared to 22% in adult OECD countries.
Another fact worthwhile to note is that private return to education tends to fall equally level of development (measured by the level of per capita income) increases.
Besides, in that location are social returns to investment in education which take into account the externalities which do non enter into the calculations of private individuals in their assessment of private return on education.
Pedagogy and Sources of Economical Growth:
The supply of human capital plays a crucial role in promoting economic growth. In an important report, Edward F. Denison has measured the relative importance of diverse sources of economic growth in the United States for the l years period, 1929-69.
Rate of economical growth in the US economy was on an boilerplate iii.3 percent during the flow 1929-69 of the written report. It will be seen from Table 9.ii that the most important source of economic growth (31.1 to 34 per cent) was advances in noesis (which includes comeback in technological knowledge) that takes place as a result of increase in education and in research and development activity. The side by side important source of economic growth was increase in the quantity of labour force (i.east., more work done) as measured past increase in hours worked by labour which contributed virtually 28.7 per cent during the menstruum of study.
Contrary to expectations of economists, accumulation of concrete capital contributed only xv.8 per cent during the entire period (1929-69) and 21.6 per cent during 1948-69 to the growth in GDP in the United States. For the entire period of study (1929-69) increase in education (i.e., number of years spent in schools, colleges and universities) contributed near the same as aggregating of physical upper-case letter (fourteen.1 per cent as confronting 15.8 per cent of physical capital. However, if we order the contribution of increased pedagogy and advances in cognition, their contribution is as high as about 45 per cent to growth.
Other sources include the efficient use of available resource, economies of scale, a shift of labour strength from depression-productivity agricultural sector to higher productivity industrial sector which contributed about 10 per cent to growth in GDP. It may however exist noted that Denison could not measure directly the contribution of advances in noesis. He measured the contributions of other 4 sources of growth, namely, more labour work, accumulation of concrete capital, increased education, and others, and assumed that all economic growth that could not be explained by other sources was the contribution of advances in knowledge.
As it pays to the individual to invest in human being uppercase (pedagogy or skill formation), similarly, the community as a whole can raise its consumption or living standards by investing in human capital.
4. Measuring Contribution of Education to Economic Growth:
Several empirical studies made in developed countries, especially the U.S.A., regarding the sources of growth or, in other words, contributions made by various factors such every bit physical capital, human being-hours, (i.eastward., physical labour), education etc. have shown that education or the development of human capital is a pregnant source of economic growth.
It may be pointed out that economists generally hold that while some investments in education are ‘economic’ in the sense that they promote growth directly, other expenditures on teaching and development of the human resources are basically of the course of ‘social investment’ which, therefore, should exist determined residually. It is not possible to separate out the consumption and investment parts of the expenditure on didactics so that it is very difficult to estimate the rate of financial return on education in the aforementioned manner as in the case of a manufactory or a dam. At all-time, i can only recognize the probable importance of the expenditure on instruction in the procedure of economic growth.
The interpretation of return on investments in teaching or human capital is beset with many difficulties. The fact is that human resource development encompasses a broad field. It cannot be solely examined in economic terms. For instance, it is not very realistic to approximate the return on education purely in terms of the increases in private incomes or the income of the economy taken as a whole. Also, the increases in productivity practise not past themselves constitute the effectiveness of human capital. Even so these considerations, economists have attempted to measure the contribution of education to economic growth solely on the ground of economic criteria.
In broad outline, the basis on which return and therefore, part of investment in human resources, specially teaching, has been sought to be incorporated in the mainstream of economical analysis.
The following are the main approaches that have been developed to guess the productivity of investment in didactics:
1. The Balance Approach or Product Part Arroyo:
In that location have been some attempts to estimate the proportion of the measured increase in gross national product owing to didactics. This is sought to be washed by first determining the increase in gross national product on account of the measurable inputs of labour and capital letter. So this figure is subtracted from the figure of GNP, to get a ‘residue’ which represents the increment in Gdp due to the improvements in the quality of labour as a upshot of educational activity.
Professor Solow who was one of the offset economists to measure the contribution of human capital to economical growth, estimated that for United States between 1909 and 1949, 57.5per cent of the growth in output per man-hour could be attributed to the residual factor which represents the effect of the technological alter and of the improvement in the quality of labour mainly as a consequence of education. He estimated this residual factor determining the increase in the total output on business relationship of the measurable inputs of upper-case letter and labour (man hours). He then subtracted this effigy from the total output to get the contribution of remainder factor which represented the effect of instruction and technological change, the physically immeasurable factors.
As explained above, Denison, another American economist, made further refinement in estimating the contribution to economic growth of various factors. Denison tried to separate and measure the contributions of various elements of ‘residual factor’. According to the estimates of Denison, over the flow 1929-82 in the USA during which total national output grew at the rate of ii.9 per cent per annum, increase in labour input accounted for 32 per cent, the remaining 68 per cent was due to the increase in productivity per worker. He and so measured the contributions of education of per worker, majuscule formation, technological change and economies of scale.
Denison found that 28 per cent of contribution to growth in output due to growth in labour productivity was due to technological change, 19 per cent to capital formation and 14 per cent due to education per worker and nine per cent points due to economies of scale. It is thus clear that educational activity and technological progress together fabricated 42 per cent (14 + 28) contribution to growth in national product.
Nevertheless, the above estimates are non fully reliable. The bones reason for this is that the methods used in calculating the contribution of education, are non free from flaws. Moreover, the data which have been used in the calculations applies merely to formal education. Information technology completely ignores on-the-job grooming. Also, only private return on instruction is measured. But education makes a considerable social contribution likewise in the form of increased mobility, adaptability and the growth of practical applied science. In this sense, these calculations make underestimation of the contribution of education.
There being interrelation betwixt capital letter formation, technology and growth of knowledge, the component in the residual ascribed to increased cognition may, in fact, include some upper-case letter avails. But, in these methods no distinction has been made between formal and informal education. Again, the differences in the quality or content of education have been ignored.
Notwithstanding these limitations, these estimates highlight the significance of the improvements in the quality of human being resources through education, in the process of economic growth.
2. Rate of Render Arroyo– Further Elaboration:
The contribution of teaching to economic growth has also been measured through the rate of render approach. In this approach charge per unit of render is calculated from expenditure made past individuals on education and the measurement of the flow of an individual’south future earnings expected to consequence from didactics. The nowadays value of these is and so calculated by using appropriate disbelieve rate. For calculating the nowadays value of future earnings with educational activity the appropriate nowadays value formula is used. This method has been used past Gary S. Backer who measured income differential arising from the cost or expenditure incurred on acquiring a higher educational activity in the United States. His estimates show that the rates of render on education in the The statesA. for urban white population were 12.5 per cent in 1940 and 10 per cent in 1950.’
Another written report on similar lines was made by E.F. Reneshaw. He used Schultz’southward before estimates, for USA of total earnings forgone and the toll of education in high schools, colleges and university. Doing this, he found that the boilerplate return on education ranged between 5 and 10 per cent for the period 1900 to 1950.
It is worth noting that estimates of rate of return on investment in education are based upon private rates of returns to individuals receiving teaching. However, by assuming that differences in earnings in a market economy reflect differences in productivity, the charge per unit of return on investment in education is taken to exist the effect of education on the output of the state.
However, these estimates of the return on education are valid only to the extent to which the underlying assumptions are valid. The expenditure on education has 2 components- the futurity earnings and the future consumption. While the educational investment results in increment in the future earnings, information technology likewise entails the consumption element in the sense of the direct satisfaction derived from education so obtained.
The latter, i.e., the consumption component of investment in education wherein resides the source of future utilities, nowhere enters into the measured national income. To the extent these estimates ignore the hereafter utilities and other external economies of acquiring knowledge; they underestimate the returns on education.
Moreover, the earning capacity of individuals with varying educational levels is not entirely the part of formal education. Other factors such as on-the-task training, experience, family unit income, social status and natural abilities also influence the earning chapters. But the estimates of return on education take no business relationship of these other factors.
Furthermore, these estimates concentrate only on the measurement of the private rates of return on educational investment. At best, they have into account merely the indirect furnishings of teaching on the output of the land on the assumption that the earnings differentials in a market place economy reflect the differentials in productivity. But the various groups such as engineers, doctors, teachers and manual workers through collective efforts or trade unionism may distort the relative earnings in the economic system. What is more, it is difficult to even estimate the individual returns on didactics where the costs of running an educational institution are negligible. For case, in Republic of india there are a large number of unmarried instructor schools where no fee is charged from the pupils.
Once more, as has been argued past Eckaus, the cost (or price) of educated labour which is used in evaluating the charge per unit of return ought to reflect the relative scarcities of the factors involved. However, when the primary brunt of educational investment is borne by the regime, the prices of educated labour fail to reflect the scarcities of factor inputs that are so used.
Also, these estimates of rate of return on education undervalue the importance of education as a stepping stone to further teaching. The fact is that one level of teaching leads to another. As such, a comparison of individuals with primary instruction with those who lack it would merely underestimate the significance of primary didactics as the bones prerequisite to larn farther education. Further, these estimates of return on teaching provide no information as to the quantity and quality of didactics most conducive to economic development.
3. Schultz Approach – Comparing Expenditure on Education with Income Earned:
Another approach to measure the contribution of education is based upon the assay of the human relationship between expenditure on didactics and income. Using this approach Schultz studied the relationship between expenditure on education and consumer’s income and besides the relationship between expenditure on education and concrete capital formation for the United States during the period 1900 to 1956.
He found that when measured in constant dollars, “the resources allocated to education rose nigh three and a half times (a) relative to consumer income in dollars, (b) relative to the gross formation of physical capital in dollars”. This implies that the “income elasticity” of the demand for didactics was virtually 3.5 times over the period or in other words, education considered as an investment could be regarded every bit iii.five times more than attractive than investment in physical capital. It may all the same be noted that these estimates of Schultz merely indirectly reflect the contribution of education to economical growth.
In the above analysis it is explained that educational activity is regarded every bit investment and like investment in physical capital, it raises productivity of the labour and thus contributes to growth of national income. The increased earnings or higher wages made by more educated workers accept been considered as benefits not only to the private individuals, but likewise to the club as a whole. This is considering higher earnings presumably reverberate college productivity, increased output in real besides as budgetary terms.
Consumption Benefits of Instruction:
We have explained above the investment benefits of pedagogy and therefore its effects on productivity and national output. But investment benefits are the merely benefits flowing from teaching. Education also yields consumption benefits for the individual as he may “enjoy” more than education; derive increased satisfaction from his present and future personal life. If the welfare of society depends on the welfare of its private members, then the lodge equally a whole also gains in welfare as a result of the increased consumption benefits of individuals from more education. Economical theory also helps united states in quantifying the consumption benefits derived from pedagogy. In economic theory, to measure the marginal value of a product or service to a consumer we consider how much he has paid for information technology.
An private would non have purchased a product or service if information technology were not worth its price to him. Besides, an individual would have bought more units of a product if he idea that the marginal utility he was getting was more than the price he was paying. Thus relative prices of various products reflect the marginal values of different products and the amount consumed of diverse products multiplied by their prices would, therefore, betoken the consumption benefits derived by the individuals.
It may, however, be pointed out that the prices in a costless economic system are influenced past a given income distribution and the presence of monopolies and imperfections in the market structure and therefore they exercise not reflect the true marginal social values of different goods. However, an objective measure out of consumption benefits of education is hard and has however to exist constitute out. Information technology may likewise be noted that, according to the new view, economic development is not merely concerned with the growth of output but too with the increase in consumption and well-existence of the order.
Thus Prof. Amartya Sen writes, “Education tin can add to the value of product in economy and also to the income of the person who has been educated. Just even with the same level of income, a person may benefit from education in reading, communicating, arguing, in being able to choose in a more informed fashion, in being taken more seriously by others and so on”. Therefore, consumption benefits of teaching may also be regarded every bit developmental benefits.
External Benefits of Education:
Nosotros have explained above the investment benefits and consumption benefits flowing from more education both for the private and the social club. The analysis of benefits has been based on the supposition that private interests of individuals are consistent with the social good. Nonetheless, individual and social benefits do not e’er coincide; for instance, social benefits may exceed private benefits.
This is the case with the education of an individual which not simply benefits individual privately but also others. First, instruction makes people better neighbours and citizens and makes social and political life more healthy and meaningful. Secondly, the, almost of import external benefit of more than education is its effect on technological change in the economy. More than educational activity, particularly higher education, stimulates enquiry and thereby raises productivity which undoubtedly benefits the lodge.
The individual inventor may not receive earnings equal to his contribution to the research. Denison’s report of contribution of teaching to growth, whose main findings have been explained, clearly shows the external benefits of instruction. After estimating the contribution of labour (including educated labour) and concrete capital to economical growth he obtained an average residual of about 32 percentages to almanac growth of two.9 per cent in the U.S. during the period 1929-sixty. Denison attributed this to the increment in knowledge which is the direct result of research and indirectly of higher didactics.
This is in addition to fourteen per cent contribution to the annual growth made direct by increase in education. Therefore, Harris and James concludes – “If the entire residuum indeed stemmed ultimately from instruction, as some human capital enthusiasts have unsaid, this would mean that instruction, directly or indirectly, contributed over twoscore per cent of total output growth and eighty per cent of increased productivity from 1929 to 1957.” If Denison’s remainder is regarded as mainly due to research stimulated by additional educational activity, then this is indeed a major external benefit of education.
