1) Note, however, that the OITDA figures for total production do involve some double-counting of components.
2) The rate of growth of the U.S. optoelectronics industry is based on the performance of a representative sample of firms surveyed (DOC 1994, IV-14).
3) On the future growth of the Japanese and U.S. economies, see Saxonhouse 1994.
4) The purchasing power parity index used to make this adjustment is drawn from data from the Organization for Economic Development and Cooperation and appears in Kagaku gijutsu cho 1995).
5) While comparative U.S.-Japan data are available on production, investment, R&D, and firm size, only Japanese data are available on R&D program size.
6) The major optoelectronics project at the National Research Institute for Metals is "The Creation of Materials for High-Functional Optoelectronic Devices with a Liquid-Drop Epitaxy Method" (Kagaku gijutsu cho 1994).
7) While the Ministry of Education provides almost half the Japanese government support for private sector R&D across all fields, its R&D data include teaching salaries (Somucho 1995).
8) Suggestions have been made, such as those by Schaede (1995), that comprehensive, unbiased data for Government of Japan funding of private R&D are not available; however, there are, in fact, a number of sources of this type of data, such as the surveys by Somucho (1995), which make use of a stratified, random sample of firms, with corrections for nonrespondents. These surveys confirm aggregate data provided by the Japanese Government.
