Computer usage was twice as high among employees in the highest wage quartile compared with those in the lowest quartile. This relationship held for all firm sizes and lengths of job tenure. The overall average was 29.6 percent of workers using computers in the lowest wage quartile and 74.2 percent using computers in the highest wage quartile. To the extent that wage is based on the marginal value of worker product, computers are an important influence for higher worker productivity in firms of all sizes. The highest premium for computer users over nonusers was found to be in small firms in industries with the highest growth rate, where a premium of nearly 24.8 percent in wages was observed.
Women use computers at a higher rate than men in firms of all sizes.
