how to calculate labor productivity
to calculate a country s labor productivity you would divide the total output by the total number of labor hours for example suppose the real gdp of an economy is 10 trillion and the aggregate hours of labor in the country is 300 billion the labor productivity would be 10 trillion divided by 300 billion equaling about 33 per labor hour if the real gdp of the same economy grows to 20 trillion the next year and its labor hours increase to 350 billion the economy s growth in labor productivity would be 72 percent the growth number is derived by dividing the new real gdp of 57 by the previous real gdp of 33 growth in this labor productivity number can sometimes be interpreted as improved standards of living in the country assuming it keeps pace with labor s share of total income the importance of measuring labor productivitylabor productivity is directly linked to improved standards of living in the form of higher consumption as an economy s labor productivity grows it produces more goods and services for the same amount of relative work this increase in output makes it possible to consume more of the goods and services for an increasingly reasonable price growth in labor productivity is directly attributable to fluctuations in physical capital new technology and human capital if labor productivity is growing it can usually be traced back to growth in one of these three areas physical capital is the tools equipment and facilities that workers have available to use to produce goods new technologies are new methods to combine inputs to produce more output such as assembly lines or automation human capital represents the increase in education and specialization of the workforce measuring labor productivity gives an estimate of the combined effects of these underlying trends labor productivity can also indicate short term and cyclical changes in an economy possibly even turnaround if the output is increasing while labor hours remains static it signals that the labor force has become more productive in addition to the three traditional factors outlined above this is also seen during economic recessions as workers increase their labor effort when unemployment rises and the threat of lay offs looms to avoid losing their jobs 1 policies to improve labor productivitythere are a number of ways that governments and companies can improve labor productivity
