Using a multidimensional framework of CEO temporal focus (the degree to which CEOs characteristically devote attention to perceptions of the past, present, and future), we propose that a company's rate of new product introduction (NPI) is predicted by a CEO's focus on each of the three distinct time frames in interaction with environmental dynamism. Based on a longitudinal (from 1996 to 2003) analysis of 221 firms in 19 industries, we show that, in stable environments, new products are introduced faster in firms headed by CEOs with high past focus, high present focus, and low future focus. In dynamic environments, new products are introduced faster in firms headed by CEOs with low past focus, high present focus, and high future focus. These findings demonstrate how CEO temporal attentional bias shapes the rate of NPI.
