We know that if an economy increases its labor input, other things being equal, the marginal product of labor (and hence the real wage) decreases. If an economy increases its physical capital stock, meanwhile, then the marginal product of capital (and hence the economy’s competitiveness) decreases.
There is a critical tension between competitiveness and real wages. Suppose for a moment that human capital and technology are unchanging. Then an economy in which real wages are increasing must also be an economy that is becoming less competitive. Conversely, the only way in which an economy can become more competitive is by seeing its real wages decrease.
High real wages make a country less attractive for businesses—after all, firms choose where to locate in an attempt to make as much profit as possible, so, other things being equal, they prefer to be in low-wage economies. Indeed, the WEF and the WCY both use labor costs as one of their indicators of competitiveness. Our article about Compal locating in Vietnam likewise cited low wages as an attraction of the country.
But we must not be misled by this. High real wages signal prosperity in a country. Low real wages, even if they make an economy competitive and help to attract capital, are not in themselves desirable. After all, the point of attracting capital in the first place is to increase economic well-being. As an example, China has been quite successful at attracting capital, in large part because of low real wages. As the country has become more prosperous, real wages have risen. A BusinessWeek article, commenting on the increasing wages in the country, observed the following: “The wage issue has started to affect how companies operate in China. U.S. corporations and their suppliers are starting to rethink where to locate facilities, whether deeper into the interior (where salaries and land values are smaller), or even farther afield, to lower-cost countries such as Vietnam or Indonesia. Already, higher labor costs are beginning to price some manufacturers out of more developed Chinese cities such as Shanghai and Suzhou.” [***“How Rising Wages Are Changing the Game in China,” Bloomberg BusinessWeek, March 27, 2006, accessed June 29, 2011,http://www.businessweek.com/magazine/content/06_13/b3977049.htm.***] In other words, increasing real wages are making China less competitive. But this tells us that China is getting richer, and workers in China are able to enjoy improvements in their standard of living. This is a good thing, not a problem.
What we really want are policies that will increase both competitiveness and real wages at the same time. The only way to do this is by increasing the stocks of human capital, knowledge, and social infrastructure (there is little a country can do to increase its stock of natural resources). There are no easy or quick ways to increase any of these. Still, important policy options include the following:
- Invest in education and training. Overall economic performance depends to a great degree on the education and skills of the workforce. This is one reason why countries throughout the world recognize the need to provide basic education to their citizens. It is worthwhile for countries to build up their stock of human capital just as it is worthwhile for them to build up their stocks of physical capital.
- Invest in research and development (R&D). The overall knowledge in an economy is advanced by new inventions and innovations. The romantic vision of invention is that some brilliant person comes up with a completely new idea. There are celebrated examples of this throughout human history, starting perhaps with the cave dweller who had the idea of cracking a nut with a stone and including the individual insights of scientists like Louis Pasteur, Marie Curie, and Albert Einstein. But the reality of invention in the modern economy is more mundane. Inventions and innovations today almost always originate from teams of researchers—sometimes in universities or think tanks or sometimes in the R&D departments of firms. Governments often judge it worthwhile to subsidize such research to help increase the stock of knowledge. R&D expenditures in the United States and other rich countries are substantial; in the United States they amount to about 2 percent of GDP.
- Encourage technology transfer.Firms in developed countries tend to have access to state-of-the-art knowledge and techniques. To increase their stock of knowledge, such countries must advance the overall knowledge of the world. For poorer countries in the world, however, there is another possibility. Factories in poor countries typically do not use the most advanced production techniques or have the most modern machinery. These countries can improve their stock of knowledge by importing the latest techniques from other countries. In practice, governments often do this by encouraging multinational firms from rich countries to build factories in their countries. Technology transfer within a country is also important. Researchers have found that, even with a country, there can be big differences in the productivity of different factories within an industry. [***See Chang-Tai Hsieh and Peter Klenow, “Misallocation and Manufacturing TFP in China and India,” The Quarterly Journal of Economics CXXIV, no. 4, November 2009, accessed June 28, 2011, http://klenow.com/MMTFP.pdf.***] So countries may be able to increase real GDP by providing incentives for knowledge sharing across plants.
- Invest in social infrastructure. Improvements in social infrastructure are hard to implement. A government, no matter how well intentioned, cannot eliminate corruption overnight. Nor can it instantly establish a reliable legal system that will uphold contracts and protect property rights. (Even if a country could do so, it would still take considerable time for international investors to gain confidence in the system.) Improving social infrastructure is, for most countries, a struggle for the long haul.
We should ask whether government needs to play a role in any of this. After all, individuals have an incentive to invest in their own education. Many people find it worthwhile to pay for undergraduate or graduate degrees because they know they will get better, higher paying jobs afterward. Similarly, firms have a lot of incentive to carry out R&D because a successful invention will allow them to earn higher profits.
There is no doubt that these private incentives play a big role in encouraging the advancement of knowledge. Still, most economists agree that private incentives are not sufficient. Particularly in poor countries, people may not be able to afford to pay for their own education or be able to borrow for that purpose, even if it would eventually pay off for them to do so.
Because knowledge is nonrival and frequently nonexcludable, not all the benefits from R&D flow to the firms that make the investment. For example, suppose a firm comes up with some new software. Other firms may be able to imitate the idea and capture some of the benefits of the invention. (Although the United States and other countries have patent and copyright laws to help ensure that people and firms can enjoy the benefits of their own inventions, such laws are imperfect, and firms sometimes find that their ideas are copied or stolen.) Private markets will do a poor job of providing nonrival and nonexcludable goods, so there is a potential role for the government.
Similar arguments apply to much social infrastructure. The provision of roads is a classic function of government because they are again (most of the time, at least) nonrival and nonexcludable. And the establishment of a reliable legal system is one of the most basic functions of government.
KEY TAKEAWAY
In some leading studies, the items that we have identified as components of social infrastructure and human capital are included as key determinants of competitiveness. Overall, the marginal product of capital is a good indicator of the competitiveness of a country.
Governments take actions to increase their competitiveness and the real wages of their workers by encouraging the accumulation of human capital, knowledge, and the transfer of technology.

How could a policy to increase the inflow of capital lead to a decrease in competitiveness? What does this inflow of capital do to the real wage of workers?
