Introduction
Human capital refers to the knowledge and acquired skills a person has that increase his or her ability to conduct activities with economic valueWorkers add to their stock of human capital throughout their lives, especially via education and job experienceCombination of …. (Fitz-enz, 2000) • traits brought into job • ability to learn• motivation to share

The Schooling Model
A person’s decision maximizes the present value of lifetime earnings
The rate of discount (r) plays a crucial role in determining whether a person chooses to go to school Wage-Schooling Locus : salary for each level of schoolingMarginal Rate of Return to Schooling : How much earnings increase if a person stays in school 1 more yearStopping rule : when it is optimal to quit school and enter job market (MRR=r)

Factors That Lead Different Level of Schooling
Differences in the Rate of Discount Different schooling decisions simply place them at
different points of the common locus
Differences in Ability Higher ability levels shift the MRR to the right, so,
earnings gain resulting from an additional year of schooling outweighs the increase in forgone earning

Signaling
Education does(needs) not increase productivity at all, but signal a worker’s qualifications to potential employers who do not have private information
Education increases earnings not because it increases productivity but because it certifies that the worker is cut out for smart worker
Self selection constraints
1. Level of education of signaling must be such that non-smart workers are unwilling or unable to attain it.
2. Achieving given level of education must be cheaper for the high smart workers than for non-smart worker

On the Job Training
Training increases a worker’s productivity (HC stock) after trainingTraining is an investment with initial costs and expected future returnsThe returns are lost in the event of a separation• Should the firm invest?
Not if the skills are easily portable (worker can leave)• Should the worker invest?
Not if the skills are firm-specific (firm can layoff)

Who Bears Costs of Firm Specific Training?
Since there is no commitment to stay on the part of the worker after training occurred firms will not want to bear the costs of training when skills are generalSince there is no certainty that the job will remain profitable in the future, the employee will not want to bear the costs of training for skills that can be valued only by the current employer (specific)

Predictions of Human Capital
When skills are transferable…
Employees should be bearing the cost• Wages of trainees (compared to non
trainees) should be lower during training • Employer can offer what the market pays
for the new skills acquired after training
Given that training increases skills• Wages of trainees (compared to non trainees)
should be greater after training at a given employer

Predictions of the Human Capital (Cont.)
To reduce transaction costs after firm-specific training • Workers should be paid above the market
value of their transferable skills.• Paying above market should minimize
transaction(search) cost.
But—if contracts can be renegotiated, the firm does not have to raise wages until faced with a potential quit (Beaudry and DiNardo ).

The Mincer equation captures the important empirical regularities
1) increase in earnings with schooling 2) concavity of log earnings in experience 3) parallelism in log earnings experiences profiles for
different education groups
log w = rs + β1t – β2t2 + other variables
Mincer Equation (1994)

Executive Pay (Murphy & Zabojnik, 2004)
Base salary and bonuses of Forbes 800 CEOs increased from $700,000 in 1970 to 2.2 million in 2000
In 1980, CEOs received about 42 times the average of workers. By 2000, they were paid 475 times the average workers (Milkovich & Newman,2002)

Possible Explanations on CEO Compensation
Social Comparison : relationship to othersEconomic Approach : reward to success, depends on company sizeAgency Theory : self-motivated behaviorFat-Cat Theory : rent seekingHuman Capital Theory : increasing investment on human capital, type of required skill

Hiring Sources-Internal or External

Hiring from Outside
Hiring from outside• foregoes valuable specific skills available only through
internal promotions• able to hire from a larger opportunity set of managers • allows better matching of managers and firms
Demougin & Siow (1994)• Outside hires involve hiring and replacement costs which
are assumed to be higher than the costs of training and promoting from within
• Internal labor market with high value for firm-specific skills
![Page 25: Human Capital : Theory And Application](https://reader033.vdocument.in/reader033/viewer/2022061121/546eb0aaaf7959fa188b4614/html5/thumbnails/25.jpg)
Executives as Human Capital
As firm-specific capital becomes relatively less important, the benefit of better matching becomes large relative to the cost of (lost) specific capital• prevalence of outside hires will increase• higher wages for outside hires as the general component of
skills becomes relatively more important than the firm-specific part of skills
Potential reason for increasing pay + increasing outside hire is the change in the composition of managerial skills toward more general (market valued) skills CEOs skills are transferable across firms and industries Greater breadth of knowledge helps management of any
company Any firm-specific information is more easily accessible than
before (computerization)

Discussions
Is education really improving productivity or just signaling?
How can we measure the value of human capital?
What are the implications of human capital theories for HRD specialists?
