foreign exchange price close to a market-clearing rate; increasing capital-saving, technological change in agriculture; locating new industries in rural areas; and providing more schools, housing, food, sewerage, hospitals, health services, roads, entertainment, and other amenities.

However, such expenditures to reduce urban migration may reach diminishing returns quickly. Unemployment among even a fraction of urban migrants may be preferable to widespread low worker productivity in rural areas. In some instances, the problem of urban migration may be more a political than an economic one.

APPROPRIATE TECHNOLOGY

In general, appropriate technologies in LDCs use more unskilled labor than in DCs. The use of more appropriate technology can be stimulated by (1) intraindustry substitution, (2) interproduct substitution, (3) greater income equality, (4) providing fewer refined products and services, (5) government purchase of labor-intensive goods,

(6)making sounder choices among existing technologies, (7) factor substitution in peripheral or ancillary activities, (8) using less-modern equipment, (9) the local generation of technologies, and (10) the local adaptation of technologies. In addition, policies reducing factor price distortion, as discussed in a subsequent section, encourage the use of more appropriate technology. Let us examine the items in this list more carefully.

1.Encouraging the production of more labor-intensive goods within each industry is possible (for example, manufacturing cotton shirts rather than nylon and sandals instead of fancy leather shoes).

2.A single need may be fulfilled by several goods whose production varies in labor intensity. Housing needs may be more or less fulfilled by the sidewalks of Kolkata, caves, mud huts, multistory apartments, single-family houses, or palaces. In Kolkata bamboo-reinforced mud huts with tin roofs are more labor-intensive (and affordable) than Western-style, single-family dwellings.

3.Macroeconomic studies indicate that goods consumed by the poor are somewhat more labor-intensive than those consumed by the rich. Government policies, including progressive taxes, the subsidized distribution of public goods and essential commodities, and high tariffs or excise taxes on luxury items, may improve income equality. Such policies are likely to increase the demand for labor-intensive goods, such as cotton shirts, sandals, mud huts, and ungraded rice, and reduce the demand for more capital-intensive, luxury goods, particularly imports (Edwards 1974:20; Morawetz 1974:505–506, 512–514).

4.One can remove luxury components from existing goods and services. Poorquality soap produced with labor-intensive techniques can perhaps substitute for Western detergents. Traditional medicine as practiced by barefoot doctors in China may be used instead of the high-income medicine from the West.

5.Government can influence employment by directing official purchases toward labor-intensive goods.

6.Planners or entrepreneurs may choose a more labor-intensive existing technology. However, David Morawetz’s (1974:515–523) survey concludes that the substitution of labor for capital is drastically limited depending on the good specified for production. Labor-intensive methods in textiles, brick-making, road-building, and iron and steel output may be greatly limited if high-quality products are to be produced.

7.Peripheral and ancillary activities, such as materials receiving, handling, packaging, and storage, probably offer more factor substitution than materials processing. It is usually possible to use people instead of forklifts and conveyer belts.

8.Using less modern equipment from DCs (for example, animal-drawn hay rakes or precomputer office equipment) offers some possibilities for more labor-intensive approaches. However, older equipment in good condition is usually not readily available from the industrialized countries.

9.The LDCs can generate technology locally. During the Cultural Revolution from 1966 to 1976, Chinese managers, engineers, and workers were compelled to be inventive, because they were cut off from the outside world. Although Chinese factory workers learned to make their own tools and machines, it was later admitted that this approach was more costly than using available technology.

The LDCs open to outside techniques can generate some technology through industry research or research organizations designed specifically to producing technology appropriate to their needs and resources. However, many government institutes have failed in developing appropriate technology. Industrial research is usually best done in the context of the producing unit by entrepreneurs, managers, engineers, technicians, and marketing specialists familiar with the industry and the work force. But even this work on labor-intensive technology will not be carried out if factor and product prices are distorted (see later).

Perhaps the most successful example of generating appropriate technology is the high-yielding wheat varieties used in the Green Revolution in Mexico, India, and Pakistan. Appropriate technology institutes also have been effective in developing natural resources and infrastructure where there is little incentive for private research.

10.Foreign technology may be scaled down to fit LDC skills and resources. Such adaptations in South and Southeast Asia include a five-horsepower tiller, a lowlift water pump, a McCormick-style thresher, and a jeep-type vehicle (Khan 1974:223–233).

Sometimes adaptation may, however, require costly use of scarce engineers, managers, and other skilled persons. It may be cheaper to transfer the technology outright rather than to spend the resources to modify it.

Nor may appropriate technologies always save capital, as it is not the only scarce factor in LDCs. Skilled entrepreneurs, managers, government administrators, and labor may be scarce as well. Thus, capital-intensive, machine-paced, or processoriented operations, which save on scarce management, may be appropriate in some cases. For example, modern factory methods for making shoes and wooden furniture

328Part Three. Factors of Growth

use more capital per worker than cottage methods but save on skilled labor, as each operative needs a narrower range of skills than the shoemaker or carpenter who makes the whole product. Thus, if skilled labor is a limitation, using the more modern, capital-intensive methods may be suitable (Morawetz 1974:517).

To conclude this section, there is some scope for more appropriate technology to increase the use of labor. Nevertheless, cheaper alternative technologies to those used in DCs are not as widely available as many economists have thought.

POLICIES TO REDUCE FACTOR PRICE DISTORTION

The LDCs can increase employment by decreasing distortions in the prices of labor and capital. These distortions can be reduced through the following policies:

(1)curtailing wages in the organized sector, (2) encouraging small-scale industry, (3) decreasing subsidies to capital investors, (4) revising worker legislation – reviewing termination practices and severance payment requirements, (5) reducing social security programs and payroll taxation, (6) increasing capital utilization, and

(7)setting market-clearing exchange rates.

1.Reducing wages increases employment opportunities when the price elasticity of labor demand (minus the percentage change in the quantity of labor demanded divided by the percentage change in the wage for a unit of labor) is greater than one (or elastic). However, wage cuts are not effective when labor demand is inelastic. Labor demand is more inelastic (1) when product demand is inelastic,

(2)the smaller the fraction labor is of total cost, (3) the less other factors can be substituted for labor, (4) when factor supplies other than labor are inelastic, and

(5)the more inflexible the product’s administered price (Samuelson 1980:525). Moreover, although there may be some labor aristocrats around, they do not comprise the bulk of LDC wage earners. Furthermore, care should be taken not to weaken the ability of trade unions to protect worker rights and income shares against powerful employers.

2.Encouraging the informal sector, especially small-scale industry, usually reduces unit wage costs and has a favorable employment effect. Firms with fewer than 50 workers employ over half the industrial labor force in LDCs, including 71 percent in Colombia, 70 percent in Nigeria, and 40 percent in Malaysia (43 percent in Japan and 34 percent in Switzerland!).

Small firms have a more favorable employment effect than large firms, because they require less capital and more labor per unit of output and because their factor prices are much closer to market prices. Wage legislation often does not apply to, or is not enforced in, small firms; their wages are lower than in large ones. Additionally, the small firm’s less-subsidized capital costs are close to market rates.

Government can encourage small-scale industry through such policies as industrial extension service, technical help, and preferred, official buying. However, subsidized credit and imports for small firms merely encourage the use of more capital-intensive techniques (Morawetz 1974:524–526).

9. Employment, Migration, and Urbanization

3.As just implied, a country can decrease capital-intensive techniques and unemployment by not subsidizing capital and credit.

4.A number of economists contend that worker legislation in many LDCs holds back industrial employment growth as much as high wages. Such legislation makes it difficult to fire an employee and requires large severance pay when termination occurs. These economists reason that employers may not hire extra workers when they see opportunities for sales expansion if they know that they will not be able to release them if the expansion is only temporary. So far, evidence fails to demonstrate that the effect of these worker policies is positive.

5.A reduction in social security payments and payroll taxes will increase the demand for, and supply of, labor at a given wage and thus increase employment. However, the cost of these policies would be a reduction in overall savings and an increase in poverty among the aged, physically impaired, and in families losing a breadwinner.

6.The LDCs can reduce foreign trade and currency restrictions to raise the price of foreign exchange to a market-clearing rate. This rate discourages using foreignmade capital goods by raising their domestic currency price. This increase in the price of capital will stimulate the greater use of labor-intensive techniques. Furthermore, a foreign exchange rate close to equilibrium is probably a more effective policy for promoting exports and import replacements than subsidies, tariffs, quotas, and licenses, all of which distort the efficient allocation of resources.

Additionally, a simple way of increasing employment is to utilize capital stock more intensively by working two or three shifts rather than one. Since LDCs appear to have low capital utilization rates compared to DCs, employment could be substantially increased if there were enough skilled managers and supervisors for extra shifts.

EDUCATIONAL POLICY

The challenge here is to reform the educational system to achieve a balance between LDC educational output and labor needs. Several strategies are suggested.

1.Where politically feasible, educational budgets in many LDCs should grow more slowly and be more oriented toward primary education and scientific and technical learning. The problem of unemployed secondary school graduates and dropouts is usually greatest where secondary education has expanded rapidly in recent years. In addition, many secondary school graduates are trained in the humanities and social sciences but lack the scientific, technical, and vocational skills for work in a modern economy. Even though rapidly expanding primary education may increase unemployment, such a negative effect is somewhat offset by the higher literacy rate achieved and increased income equality. (See also Chapter 10, which indicates that the rate of return to primary education in LDCs is generally higher than to secondary education.)

2.Subsidies for secondary and higher education should be reduced, as they encourage a surplus of educated people, some of whom become unemployed. In addition as indicated in Chapter 10, they redistribute income to the rich. However, in

330 Part Three. Factors of Growth

order to improve income distribution, subsidies might be made for scholarships for the poor.

3.Increase the flexibility of pay scales. Occupational choice should change with shifts in supply and demand. When there is a surplus of engineers or lawyers (as in India in the early 1970s), salaries should fall, so that both graduates and prospective students will shift to another field.

4.Inequalities and discrimination in both education and employment should be minimized. To reduce the burden on the educational system and improve its performance, LDCs should pursue policies that encourage greater reliance on jobrelated learning experiences for advancement; they should use successful work experience as a criterion for educational advancement and reduce discrimination in hiring and promotion. In some instances in which the highly educated are severely underutilized, it is because ethnic, regional, and sex discrimination keeps the most qualified workers from finding appropriate jobs.

5.Job rationing by educational certification must be modified. Frequently, overstated job specifications make overeducation necessary for employment. Requiring a secondary education to sweep the factory floor or a university degree to manage a livestock ranch is counterproductive. Employers should be encouraged to set realistic job qualifications, even though the task of job rationing may be made somewhat more difficult (Edwards and Todaro 1974:29–30; Squire 1981:194–205).

The policies on migration, education, technology, and factor price distortions discussed in the last four sections may not always be politically feasible. Governments sometimes lose the political support they need to function when they revise labor codes, curtail wages, eliminate capital subsidies, adjust foreign exchange rates, reduce secondary and higher education subsidies, or make government pay scales more flexible.

GROWTH-ORIENTED POLICIES

Clearly, South Korea and Taiwan achieved rapid employment growth partly through policies such as those we have discussed and partly through rapid economic growth. Other things being equal, faster rates of growth in production contribute to faster employment growth. But other things are not always equal, as suggested by our discussion on rural–urban migration, appropriate technology, factor prices, and the educated labor market.

Conclusion

1.Production depends on the flow of natural resources, capital, labor, entrepreneurship, and technology per unit of time.

2.The openly unemployed, those without a job who are actively looking for one, are usually urban, 15–24 years old, and among the well educated.

9. Employment, Migration, and Urbanization

331

3.The underemployed, the visibly active but underutilized, the impaired, and the unproductive are all underutilized in LDC labor forces.

4.The labor force grows faster than job opportunities, so unemployment grows. About one-third of the labor force in least-developed Africa is employed outside agriculture. The labor force in these countries is growing at about 2.7 percent per year. If employment in agriculture remains constant, the industrial sector must increase employment by more than 8 percent yearly to absorb this extra labor. Industrial employment rarely grows this fast in these countries.

5.Although many economists believe that there is widespread disguised unemployment, or zero marginal productivity, in LDC agriculture, the available evidence does not support the contention.

6.Rural–urban migration contributes almost as much to the rapid growth of the urban labor force in LDCs as population growth. Lewis argues that an unlimited supply of underutilized farm labor migrates to urban areas for wages only slightly in excess of rural wages. Harris and Todaro indicate, however, that farm workers considering a move to an urban area consider urban–rural differences in unemployment as well as wages.

7.Keynesian unemployment from deficient aggregate demand is not important in LDCs because of the slow response in output to demand increases, ineffective fiscal policy, rural–urban migrants in the labor market, and possible tradeoffs between employment and output from inappropriate technology.

8.Technology designed for the industrialized countries, which have a relative abundance of capital and scarcity of labor, is often not suitable for LDCs, with their abundant labor and scarce capital. This inappropriate technology increases unemployment. However, in some instances, such as in the iron and steel industries, the capital-labor ratios may be invariable. The LDCs must use the same technology as DCs in such a case.

9.Capital may be priced higher and labor priced lower than equilibrium prices in LDCs because of government wage and social legislation, trade union pressures, and a low price for foreign exchange.

10.The LDC unemployment is higher among the educated than the uneducated because the educated may have unrealistic earnings expectations or job preferences and because wages paid to educated workers are often inflexible.

11.Policies to reduce unemployment include programs to reduce fertility; encourage rural development and amenities; substitute labor-intensive production techniques for capital-intensive approaches; substitute products that use labor more intensively; redistribute income to the poor; increase official purchases from small-scale, labor-intensive firms; generate new technology locally; adapt existing technology; curtail wages in the organized sector; decrease subsidies to capital; increase capital utilization; set equilibrium foreign exchange rates; resist pressures for a too rapid expansion of upper-level education and refuse to subsidize this level of education; increase the share of spending for primary schooling; stress scientific and technical education; improve wage flexibility at the higher levels; and reduce job rationing by educational certification.

GUIDE TO READINGS

Reliable data on LDC unemployment are hard to acquire. World Bank (2003h:50– 52) and subsequent World Development Indicators in paper or on CD-ROM have unemployment figures; the problem with these figures in LDCs is that those with a

9. Employment, Migration, and Urbanization

333

large agricultural sector have little open unemployment, thus making comparison difficult.

The International Labour Office’s annual World Employment Report has information on structure and evolution of the labor force, labor force participation, distribution of the labor force by sector, employment growth, real wages by sector, employment of professionals and technicians, public spending on education and vocational education, economically active population, training programs, education and growth, and employment of women; the ILO’s World Labour Report has data on labor market demographics, dependency ratios, aging, fertility, life expectancy, social security expenditure, pensions, health care, unemployment benefits, poverty, and income distribution. The ILO’s Global Employment Trends for Women 2004 has detailed data on the employment of women.

Morawetz (1974:492–526) analyzes the inability of modern industry to provide adequate employment opportunities for the rapidly growing LDC labor force. Kao, Anschel, and Eicher (1964:129–144) have a comprehensive review of the theoretical and empirical literature on disguised unemployment in agriculture. Lewis (1954:139– 191), Harris and Todaro (1970:126–142), Stark (1984:475–486), and Stark and Levhari (1982:191–196) discuss the determinants of migration from rural and urban areas. World Bank (2003i:107–132) discusses “Getting the Best from Cities,” including a section on railway dwellers in Mumbai managing their own resettlement (p. 125). Williamson (1988) analyzes migration and urbanization.

Peattie examines different concepts of the informal sector and why they are so fuzzy. For a critique, see Khundker (1988:1263–1265).

10 Education, Health, and Human Capital

Scope of the Chapter

In the mid-19th century, Abraham Lincoln was esteemed not only for his wit and rhetoric but also for physical prowess in splitting rails and wresting.

Many readers know the ballad of John Henry, born with a “hammer in his hand.” The legend celebrates the raw strength of that “steel-driving man” who, in the late 19th century, raced a steam drill in digging a West Virginia railway tunnel. Man defeated machine, but, alas, John Henry worked so hard that he “keeled over and died.”

Since John Henry, humankind has reduced requirements for manual work as skilled labor and capital have increasingly replaced unskilled labor. As human work has been deskilled, the wage of unskilled relative to skilled work has fallen.

This chapter focuses on education, skilled labor, health, and human capital. Higher income per capita is strongly associated with lower mortality and higher school completion (World Bank 2004i:35).

The Nobel laureate Simon S. Kuznets (1955b:39) argues that the major stock of an economically advanced country is not its physical capital but “the body of knowledge amassed from tested findings and discoveries of empirical science, and the capacity and training of its population to use this knowledge effectively.” The contrast in economic growth between Japan and Germany, on the one hand, and third-world countries, on the other, after World War II illustrates the importance of labor quality. Although much of the physical capital in Germany and Japan was in ruins or depleted, their economies grew rapidly after the war, as the skill, experience, education, training, health, discipline, and motivation of the existing labor force remained intact.

Why is labor productivity higher in DCs such as Japan and Germany than in LDCs? In this chapter, we are not interested in productivity differences attributed to capital and land. Rather, we focus on the effect of variables, such as (1) formal education and training; (2) socialization, child rearing, motivation, and attitudes; and (3) the health and physical condition of the labor force, including a section on HIV infection and the AIDS epidemic.

Investment in Human Capital

Remember the discussion of human capital in Chapter 5. Theodore W. Schultz (1964) argues that

Capital goods are always treated as produced means of production. But in general the concept of capital goods is restricted to material factors, thus excluding the skills and other capabilities of man that are augmented by investment in human capital. The acquired abilities of a people that are useful in their economic endeavor are obviously produced means of production and in this respect forms of capital, the supply of which can be augmented.

Economic Returns to Education

Education helps individuals fulfill and apply their abilities and talents. It increases productivity, improves health and nutrition, and reduces family size. Schooling presents specific knowledge, develops general reasoning skills, causes values to change, increases receptivity to new ideas, and changes attitudes toward work and society. But our major interest is its effect in reducing poverty and increasing income.

The World Bank economists George Psacharopoulos (1985:1325–1343; 1994: 1325–1343) and Maureen Woodhall (Psacharopoulos and Woodhall 1985:21–22, 196–197) indicate that the average return to education (and human capital) is higher than that to physical capital in LDCs but lower in DCs. Among human investments, they argue that primary education is the most effective for overcoming absolute poverty and reducing income inequality. This is especially true in sub-Saharan Africa, where less than three-fourths of the children of primary school age are enrolled in school.

Yet, in the 1960s, planners in developing countries favored secondary and higher education that met the high-level labor requirements of the modern sector rather than establishing literacy and general education as goals for the labor force as a whole. George Psacharopoulos, in a study in 1994 on the social rates of return to educational investment, indicates that the highest average returns are from primary education. A subsequent study (Psacharopoulos and Patrinos 2002) shows similar patterns, with returns to primary education 19 percent per year, secondary education 13 percent, and higher education 11 percent1 (Table 10-1). The higher rates of returns to primary education are consistent with diminishing returns to increased dollars per pupil. Public expenditure per student is more for higher and secondary education than for primary education. Sub-Saharan Africa spends 100 times as much per pupil for higher education as for primary education! (See Table 10-2.) Africa’s higher education costs result partly from an inability to achieve economies of scale. Thus, in the 1970s, in Ghana educating 20,000 students costs $3,500 per student, whereas in India,

1Private returns to investment in education are higher than social returns because of public subsidies to education and most studies’ lack of information on positive social externalities (Psacharopoulos and Patrinos 2002:2).
