The report reviews current literature dealing with past/present/future mechanisms to assist workers' adjustment to technological change. A basic concern of the study is what level of governmental policy, if any, is needed in this area. Part 1 is a discussion of the conceptual impact of technological change on the labor market. The four chapters of Part 1 are directed to the effect of technological change on employment as related to production function, input prices, demand shifts, and skill sector requirements; worker adjustment to technological change through private/public adjustment mechanisms; other relationships between workers and technological change; and adjustment mechanisms and social well-being. Part 2, a review of current literature from 1965 through 1973, is anticipated to be representative of total work in the area. Chapter 1 of Part 2 summarizes findings on worker displacement, analyzes policy recommendations in the literature, and indicates needed research. Chapter 2 focuses on which types of workers are affected by technological change (skill, age, sex, ethnic groups, occupation, and industry). Chapter 3 reviews the private/public adjustment mechanisms and which workers benefit most and least from these adjustment mechanisms. An extensive bibliography accompanies Part 2. (EA)
