1. The Influence of Corporate Internal Governance on the Wealth Effect of R&D Expenditure Increases Shao-Chi Chang National Cheng Kung University, Taiwan Sheng-Syan Chen National Taiwan University, Taiwan Wen-Chun Lin National Cheng Kung University, Taiwan

2. Motivation Investments in R&D are major sources of inputs for growth and competitive power The evidences for the wealth effect of R&D investments are mixed –Positive (Chan, Martin, and Kensinger, 1990) –Insignificant (Sundaram, John, and John, 1996)

3. Difficulties in R&D Valuation Information asymmetry –Not required to disclose information of R&D projects To value R&D projects is difficult –The benefits of R&D last long-run period To require R&D to be expensed is unsuitable

4. Motives for R&D Expenditure Increases Tool of earnings management –To change the timing of R&D spending Agency costs –To invest in unprofitable projects

5. The Benefits of Internal Governance To reduce information risks –To disclose credible information –To control the level of earnings manipulation To reduce agency costs –To cut down the inefficiency investments

7. Sample Design Sample period: 1988-2001 Announcement collected from Dow Jones News Database: CRSP, Compustat, Compact D, SEC proxy statement Final sample size: 243 announcements

11. Measures of Internal Governance Board Characteristics –Fraction of outside directors –Board size Ownership Structure –Blockholder ownership –Insider ownership Leadership Structure –Duality

12. Board Characteristics Outside director on the board –Serve a useful monitoring function. (Weisbach, 1988) Board size –Larger board is valuable for the breadth of its services. –Smaller board is manageable and plays a controlling function. (Jensen, 1993) –Optimal board size should be neutral to firm performance. (Lehn, Patro, and Zhao, 2004)

13. Ownership Structure Blockholder ownership (Allen and Phillips, 2000) –more incentive to monitor management –more ability to take the cost to monitor Insider ownership (Cho, 1998) –optimally diversify risk

14. Leadership Structure Duality : chairman of the board and CEO is same person Disadvantage of duality –To impair the monitoring function of a board (Lehn and Zhao, 2006) –To increase the agency problems (Fama and Jensen, 1983)

25. Conclusions and Contributions Internal governance has a impact on the valuation of R&D investments. Internal governance and growth opportunity jointly decide the value creation of R&D investments Internal governance explains the puzzle on the wealth effect of R&D expenditure increases
