Promoting Research and Development: The Government’s Role

I am pleased to speak at this conference on new building blocks for jobs and economic growth. The conference organizers have gathered an outstanding group of participants and have set an ambitious agenda. The topics you will address today and tomorrow, bearing on innovation and intangible capital, are central to understanding how we can best promote robust economic growth in the long run.

I won’t have to spend much time convincing this audience of the importance of long-run economic growth. The Nobel Prize-winning economist Robert E. Lucas, Jr., wrote that once one starts thinking about long-run growth and economic development, “it is hard to think about anything else.”1 Although I don’t think I would go quite that far, it is certainly true that relatively small differences in rates of economic growth, maintained over a sustained period, can have enormous implications for material living standards. A growth rate of output per person of 2-1/2 percent per year doubles average living standards in 28 years–about one generation–whereas output per person growing at what seems a modestly slower rate of 1-1/2 percent a year leads to a doubling in average living standards in about 47 years–roughly two generations. Compound interest is powerful! Of course, factors other than aggregate economic growth contribute to changes in living standards for different segments of the population, including shifts in relative wages and in rates of labor market participation. Nonetheless, if output per person increases more rapidly, the prospects for greater and more broad-based prosperity are significantly enhanced.

Over long spans of time, economic growth and the associated improvements in living standards reflect a number of determinants, including increases in workers’ skills, rates of saving and capital accumulation, and institutional factors ranging from the flexibility of markets to the quality of the legal and regulatory frameworks. However, innovation and technological change are undoubtedly central to the growth process; over the past 200 years or so, innovation, technical advances, and investment in capital goods embodying new technologies have transformed economies around the world. In recent decades, as this audience well knows, advances in semiconductor technology have radically changed many aspects of our lives, from communication to health care. Technological developments further in the past, such as electrification or the internal combustion engine, were equally revolutionary, if not more so. In addition, recent research has highlighted the important role played by intangible capital, such as the knowledge embodied in the workforce, business plans and practices, and brand names. This research suggests that technological progress and the accumulation of intangible capital have together accounted for well over half of the increase in output per hour in the United States during the past several decades.2

Innovation has not only led to new products and more-efficient production methods, but it has also induced dramatic changes in how businesses are organized and managed, highlighting the connections between new ideas and methods and the organizational structure needed to implement them. For example, in the 19th century, the development of the railroad and telegraph, along with a host of other technologies, were associated with the rise of large businesses with national reach. And, as transportation and communication technologies developed further in the 20th century, multinational corporations became more feasible and prevalent.

Economic policy affects innovation and long-run economic growth in many ways. A stable macroeconomic environment; sound public finances; and well-functioning financial, labor, and product markets all support innovation, entrepreneurship, and growth, as do effective tax, trade, and regulatory policies. Policies directed at objectives such as the protection of intellectual property rights and the promotion of research and development, or R&D, promote innovation and technological change more directly.

In the remainder of my remarks, I will focus on one important component of innovation policy–namely, government support for R&D. As I have already suggested, the effective commercial application of new ideas involves much more than just pure research. Many other factors are relevant, including the extent of market competition, the intellectual property regime, and the availability of financing for innovative enterprises. That said, the tendency of the market to supply too little of certain types of R&D provides a rationale for government intervention; and no matter how good the policy environment, ultimately, big new ideas are often rooted in well-executed R&D.
