Question for Economists: Calculating Real Wages

Can someone point me to the state of the art on methods for calculating real wages, especially how changes in technology are accounted for in changes in purchasing power. How, for example, is the availability of a drug or labor-saving appliance or new source of entertainment that was not available 20 years ago included in the estimate of the real wage? I know of several sources of information on this problem, largely in the semi-popular press, but am largely interested in discovering if there is a definitive academic article or book (or several) that deals seriously with this issue, and is recognized as the latest and most definitive word. Thanks.
