This paper reviews the studies on the returns to R &D investment in the United States. It discusses the analysis level,measurement model and other measurement problems such as obsolescence rate,time lag,double counting and expensing of R &D expenditures. The results of recent empirical researches are compared and summerized in six major effects of R &D:social return,private return,productvity increse,sales increase,profit increase,patent and publication increase. It is observed that the relationships between R &D investment and productivity,sales,profit,patent,publication in the U.S.firms are positive with statistical significance,and that social rate of return is much higher than private rate of return to R &D investment which is also higher than capital investment.The auther concludes that much progress has been made in this field even though yet many unsolved problems remain and suggests that empirical study on the effects or R &d investment in Korea is much needed for optimal R &D resources allocation.
