One of the theories regarding initial public offering (IPO) pricing is that the initial return y (the percentage change from offer to open price) on an IPO depends on the price revision x (the percentage change from pre-offer to offer price). Another factor that may influence the initial return is a high-tech dummy variable that equals 1 for high-tech firms and 0 otherwise. The following table shows a portion of the data on 264 IPO firms from January 2001 through September 2004. Initial Return 36.95 Price Revision High-Tech 7.84 10.51 -32.50 0 2.37 -21.84 1 picture Click here for the Excel Data File a-1. Estimate y = 60 + 6 + 62d + where the dummy variable d equals 1 for firms that are high-tech. (Round your answers to 2 decimal places.) Initial Return Price Revision + High-Tech a-2. Use the estimated model to predict the initial return of a high-tech firm with a 10% price revision. (Round coefficient estimates to at least 4 decimal places and final answer to 2 decimal places.)
