What is total factor productivity economics?

Total Factor Productivity (TFP) is the portion of output not explained by the amount of inputs used in production. The following definition describes the measurement and importance of TFP for growth, fluctuations and development as well as likely future directions of research.

How does economics define productivity?

Productivity is commonly defined as a ratio between the output volume and the volume of inputs. In other words, it measures how efficiently production inputs, such as labour and capital, are being used in an economy to produce a given level of output.

What is included in total factor productivity?

Total factor productivity (TFP) is a measure of productivity calculated by dividing economy-wide total production by the weighted average of inputs i.e. labor and capital. It represents growth in real output which is in excess of the growth in inputs such as labor and capital. It equals output divided by input.

What are the three sources of total factor productivity?

This is because the total economic productivity of a country is determined by three factors (Li and Mérette, 2005) contributing to total economic production (as measured by gross domestic product [GDP]): (1) natural resources and capital input, (2) human resources or labor input, and (3) the technological base (total …

What happens when total factor productivity increases?

When a country is able to increase its total factor productivity, it can yield higher output with the same resources, and therefore drive economic growth.

What happens when total factor productivity decreases?

A temporary increase in total factor productivity decreases the real interest rate, increases aggregate output, increases employment, increases the real wage, increases consumption, and increases investment. There are two principle differences between changes in current and future total factor productivity.

How important is productivity in economics?

Productivity increases have enabled the U.S. business sector to produce nine times more goods and services since 1947 with a relatively small increase in hours worked. With growth in productivity, an economy is able to produce—and consume—increasingly more goods and services for the same amount of work.

What is productivity in economics example?

Economic productivity is the value of output obtained with one unit of input. For example, if a worker produces in an hour an output of 2 units, whose price is 10$ each, then his productivity is 20$.

Which are the factor not considered in total factor productivity?

The Solow residual is the portion of an economy’s output growth that cannot be attributed to the accumulation of capital and labor, the factors of production.

Why is total factor productivity important?

Economists have long recognized that total factor productivity is an important factor in the process of economic growth. Total factor productivity growth is estimated as a residual, using index number techniques. It is thus a measure of our ignorance,’ with ample scope for measurement error.

What causes a decrease in total factor productivity?

U.S. total factor productivity growth has slowed since mid-2000s. Some argue that the slowdown in TFP growth reflects the reduced ability of the U.S. economy to benefit from technological advances. Gordon (2012 and 2013) suggests that technological innovation has become marginally less important for growth.

What affects total factor productivity?

The Solow residual is affected by a huge variety of technological, economic, and cultural factors. Innovation, investment in more productive sectors, and economic policies aimed at liberalization and competition all boost total factor productivity.
