The productivity paradox suggests that technology investments may not necessarily lead to increased productivity due to inaccurate measures, slow gains, and poor management. After a certain point, heavy investments in technology may not be effective in increasing productivity. Current methods of measuring productivity have limitations and may not take into account certain variables that affect productivity.
The productivity paradox is an economic explanation of how an increase in technology does not necessarily mean that there will be an increase in productivity. The term was first used by Erik Brynjolfsson, professor of management at the MIT Sloan School of Management, when he stated that there is no correlation between IT improvements and productivity. He believed that the causes of the productivity paradox are that current measures of productivity are inaccurate, private gains are at the expense of general gains, time is slow to achieve gains, and technology is poorly managed.
The productivity paradox is important because it reveals that investments in technology may not help a company or society become more productive. Statistical evidence shows that after a certain level of investment, productivity begins to stabilize as new investments are made. This means that, after a certain point, companies should not rely on heavy investments in technology if they are determined to increase productivity. Economists also feel that gross domestic product (GDP) does not necessarily increase as countries become more technological. While it may be true that the productivity paradox exists, some argue that the paradox is due to inefficient means of measuring productivity or other causes not considered in the calculations.
Methods for measuring productivity are limited and have visible weaknesses. Economists usually measure productivity by taking the percentage change in GDP and dividing it by the amount of work per hour. The main weakness of this method is that it only considers technological improvements at the time the statistics were collected. Companies tend to use the total factor productivity (TFP) method, calculated by subtracting productivity improvements from revenue per employee. The weakness of this method is that it assumes that technology investments will increase productivity, even when this is not the case.
Current methods of measuring productivity may not take into account certain variables that affect productivity due to technology, making earnings appear lower. Another potential cause is to look at the net earnings, as if a company makes a gain at the expense of competitors, the net earnings will not show any change. It is also possible that gains appear later than expected, so that they are not taken into account when measured. If management is not utilizing the new technology to its full potential or is having difficulty managing their department, the expected gains will not be realized.
