Ag Productivity On the one hand, agricultural productivity has been terrific. It moves along at a 1.67 percent annual rate, which by one estimate accounts for more than a tenth of total U.S. productivity growth for all industries. Ignoring wide swings from year to year, such as 2012's drought, the sector can more than outpace growth on the demand side. However, under Moore's Law, the amount of computing power that money can buy doubles every two years as researchers find ways to double the number of transistors per integrated circuit during that time period. And under Cooper's Law, the efficiency of use of the electromagnetic spectrum doubles every 30 months. Indeed, agricultural productivity could advance more quickly if the demand si...
