Explain the term labor productivity, or productivity for short.

The term labor productivity, or productivity for short, is used to refer either to output per worker or, in some cases, to output per hour. For the economy as a whole, productivity – output per worker – is simply real GDP divided by the number of people working.

What is the aggregate production function?

Licencing: Not defined

The aggregate production function (or GDP per worker) shows how productivity depends on the quantities of physical capital per worker, human capital per worker and the state of technology. It allows economists to disentangle the effects of these three factors on overall productivity.

Explain the term diminishin returns to physical capital

Diminishing returns to physical capital is an “other things equal” phenomenon: additional amounts of physical capital are less productive when the amount of human capital per worker and the technology are held fixed! Diminishing returns may disappear if we increase the amount of human capital per worker, or improve the technology, or both at the same time the amount of physical capital per worker is increased.

That is, when the amount of human capital per worker and the state of technology are held fixed, each successive increase in the amount of physical capital per worker leads a smaller increase in productivity.

Economies with rapid growth tend to be economies that add physical capital, increase their human capital, or experience rapid technological progress. Evidence also points to the importance of __________, __________, and __________ in fostering the sources of growth.
