Compound Interest • Suppose you put $100 in a savings account for your retirement. How much would you have in 50 years? • You need to know the interest rate. • At 1%, the savings at the end of one year will be: 100 + 100*.01 = 100 (1+.01) = 101. • At the end of two years, the savings will be: 100(1.01) + 100(1.01)(.01) = 100(1.01)(1.01) = 100 (1.01)2
Impact on Living Standards • GDP per capita grew at a rate of 2% per year for US during the last 50 years. • Japanese GDP per capita grew at a rate of 5% during the same period. • Chinese GDP per capita grew about 8% per year the last twenty years.
Real GDP per Capita • Real GDP per capita is found by dividing the Real GDP by the population: Y/POP. • We can rewrite Y/POP as Y/N times N/POP, since the Ns would cancel out when the two terms are multiplied. • Y/N is average labor productivity. • N/POP is employed portion of the population.
Growth Rate of Y/POP • Percentage growth of Y/POP will be equal to percentage growth of Y/N (Average Labor Productivity) PLUS N/POP (Share of population employed). • We can get these numbers for US from government web sites: Bureau of Labor Statistics, Bureau of Economic Analysis, Federal Reserve Bank of St. Louis.
US Experience and Forecast • Why did N/POP increase during the last 30 years? • What is expected for the future of N/POP? • How can US expect to raise average living standards in the future?
Determinants of Average Labor Productivity • Human Capital • Physical Capital • Natural Resources • Technology • Entrepreneurship and Management • Political and Legal Environment
Human Capital • Human capital of workers includes the • Talents • Education • Training • Skills
Physical Capital • Quantity and quality of machines, tools, equipment and buildings affect the productivity of labor. • How productive is a computer programmer without a computer? • Using MB vs. MC principle to allocate machinery. • Diminishing returns reduces the MB for the next machine.
Natural Resources • Abundant land, energy, raw materials will allow inputs to be cheap for producing certain products, giving a country comparative advantage in these products. • Free trade practically frees a country from the yoke of lack of natural resources.
Technology • New technologies that increase the productivity of labor is commonplace in our age. • New ways of organizing, presenting, sequencing, etc. are also considered technological advances. • Technological improvements in one area may have positive spillover effects in another industry.
Entrepreneurship and Management • Entrepreneurs take risks to introduce new products, new processes into the economy. • Societies that provide secure property rights, low and predictable taxation and independent, incorruptible legal system support the flourishing of entrepreneurial activity. (See M. Olson, Power and Prosperity.)
Entrepreneurship and Management • China in the Middle Ages was far superior to the West technologically. However, the social system stifled economic growth: application of technology to production. • Management is every day operation of the establishment. Education is supposed to reduce the incidences of wrong decisions in everyday operations.
Political and Legal Environment • It is the function of the government to provide an environment where individuals and firms are not subjected to arbitrary rules, increasing the uncertainty of efforts. • Enforceable contracts, well-defined property rights, political and social environment conducive to taking risks in production are responsibilities of governments. • Soviet example.
Worldwide Productivity Slowdown • Starting with 1973, industrialized nation experienced a significant productivity slowdown. • Slow growth brings social problems. • Redistribution can exacerbate these problems.
Why Did Productivity Slow Down? • Decline in public education? • Oil price shocks? • Poor measurement of productivity gains in service sector? • The exceptional experience of the 50s and 60s?
Costs of Economic Growth • Resources allocated to capital formation will reduce production of consumer goods. • Unsanitary, unsafe conditions for industrial workers (historical for US, current for many LDCs). • Is the sacrifice today, worth better living conditions tomorrow?
How to Increase Growth Rates? • The factors that determine average labor productivity may be enhanced by public policy.
Policies to Increase Human Capital • Education increases human capital. • Why does the government provide “free” K-12 education? • Positive externalities: Private demand does not capture all the societal benefits. • Who should decide the content of curriculum?
Policies to Promote Saving and Investment • Capital stock in a country increases through investment activities. • Investments require resources diverted from consumption goods to capital goods. • If consumers do not restrict their consumption (if they don’t save) total expenditures will exceed the value of production and inflation will ensue.
Policies to Promote Saving and Investment • High rates of saving allow a country to channel resources into capital formation. • Governments can pass laws to promote saving and laws to promote investment. • Governments also can create capital stock directly (how does it pay?)
Policies to Support R&D • Public good aspect of knowledge reduces private investment in knowledge. • Collective decision-making is required for activities with higher social benefits than individual benefits, e.g. basic research.
Legal and Political Framework • Political stability • Free and open exchange of ideas • Secure property rights • Well functioning legal system • Free markets (except for those with significant externalities)
Limits to Growth? • Will we run out of oil (natural resources)? • Market mechanisms: price incentives • Will we spoil the environment completely? • Change in tastes and preferences • Can we solve the global warming problem? • Limits to collective decision-making.
Commodity Prices FIRST published in 1864, with figures stretching back to 1845, The Economist's commodity-price index is probably the world's oldest regularly published price index. Since October 2001, our dollar-based industrials index has risen by 76%, fuelled by Chinese demand for raw materials and, in part, the weakness of the dollar. Yet in real terms, industrial commodity prices are a mere 30% of their value in 1845 http://www.economist.com/printedition/displayStory.cfm?Story_ID=3651836
