What determines Robinson Crusoe’s standard of living and why?
Because Crusoe gets to consume only what he produces, his living standard is tied to his productivity.
What is productivity?
The quantity of goods and services that a worker can produce for each hour of work.
What is the key determinant in the growth of living standards?
Growth in productivity.
What are the determinants of productivity?
Physical capital
Human capital
Natural resources
Technological knowledge
What is physical capital and why is physical capital per worker a determinant of productivity?
(Physical) capital is the stock of equipment and structures that are used to produce goods and services.
Workers are more productive if they have tools with which to work.
What is an important feature of capital as a factor of production?
It is a produced factor of production. Capital is an input into the production process that in the past was an output from the production process.
What is human capital?
The economist’s term for the knowledge and skills that workers acquire through education, training, and experience.
How is human capital similar to physical capital?
Like physical capital, human capital raises a nation’s ability to produce goods and services.
Also like physical capital, human capital is a produced factor of production.
In terms of productivity, what is an important way to view the development of human capital?
Students can be viewed as “workers” who have the important job of producing the human capital that will be used in future production.
What are natural resources?
Natural resources are inputs into production that are provided by nature, such as land, rivers, and mineral deposits.
What are the two forms of natural resources?
Renewable and Non-renewable.
Describe the role of natural resources in a nation’s standard of living.
Although differences in natural resources are responsible for some of the differences in standards of living around the world, natural resources are not necessary for an economy to be highly productive.
What is technological knowledge?
The understanding of the best ways to produce goods and services.
Describe the difference between human capital and technological knowledge.
Technological knowledge refers to society’s understanding about how the world works. Human capital refers to the resources expended transmitting this understanding to the labor force.
Describe the difference between human capital and technological knowledge in relation to productivity using the textbook metaphor.
Knowledge is the quality of society’s textbooks, whereas human capital is the amount of time that the population has devoted to reading them. Worker’s productivity depends on both the quality of textbooks they have available and the amount of time they have spent studying them.
Briefly explain why saving and investment are important for productivity.
If today the economy produces a large quantity of new capital goods, then tomorrow it will have a larger stock of capital and be able to produce more of all types of goods and services. Thus, one way to raise future productivity is to invest more current resources in the production of capital.
Why is the principle “people face trade-offs” especially important when considering the accumulation of capital?
It requires that society sacrifice consumption in the present in order to enjoy higher consumption in the future. Because resources are scarce, devoting more resources to producing capital requires devoting fewer resources to producing goods and services for current consumption.
What quickly and efficiently brings savings and investment together with minimal risk and in a transparent way, and is also a critical ingredient in the recipe for economic growth?
A well-functioning and carefully regulated financial market.
Suppose that a government pursues policies that raise the nation’s saving rate. What happens?
With the nation saving more, fewer resources are needed to make consumption goods, and more resources are available to make capital goods. As a result, the capital stock increases, leading to rising productivity and more rapid growth in GDP.
What is the property of diminishing returns?
The property whereby the benefits from an extra unit of an input declines as the quantity of the input increases.
Describe how capital accumulation is subject to diminishing returns.
When workers already have a large quantity of capital to use in producing goods and services, giving them an additional unit of capital increases their productivity only slightly.
What is the first important implication of diminishing returns on to capital accumulation.
In the long-run, the higher saving rate leads to higher level of productivity and income, but not to a higher growth in these variables.
What is the second important implication of diminishing returns on to capital accumulation.
The catch-up effect.
What is the catch-up effect?
The property whereby countries that start off poor tend to grow more rapidly than countries that start off rich.
