Suppose that you observed several key characteristics of a random sample of firms in your industry. You know that the semi-partial correlation of firm Productivity (Y) with R&D (Z) investment holding amount of Labor (X) fixed is positive. Furthermore, suppose you know that the covariance of R&D investment and amount of labor is positive. How will the coefficient on Labor when you run the regression of Productivity on Labor and R&D investment relate to the coefficient on Labor when you run a regression of Productivity on just Labor?
