[Excerpt] Hendricks and Kahn's book is a major contribution to the literature on wage indexation. The authors, together with a team of graduate assistants, have painstakingly put together a data file from Bureau of Labor Statistics and Bureau of National Affairs sources that covers over 10,000 individual contract negotiations during the 1967-82 period. A major portion of their book is devoted to econometric analyses of these data; specifically, analyses of the determinants of COLA incidence, the determinants of COLA strength, the effect of COLAs on wage inflation, and the effect of COLAs on strike activity. Earlier versions of some of these analyses have appeared in previous publications by the authors, but there is enough new material here to hold the interest of even the well-read reader.
