The objective of this paper is to study the market valuation of R&D investments in the Taiwan stock market from July 1988 to June 2002. The motivation stems from Taiwan's recent economic transition from a labor-intensive, then to a capital-intensive, and currently to a technology-based economy. The results support not only the existence but also the persistence of R&D-associated mispricing. More importantly, it has become stronger as the electronics industry gradually dominates the economy. Firstly, R&D-intensive stocks tend to outperform stocks with little or no R&D. Secondly, the R&D-intensity effect cannot fully be attributed to firm size. Thirdly, the R&D-intensity effect is more pronounced for firms in the electronics industry after 1996. (Dev Econ/GIGA)

This paper provides a model for valuing stocks that takes into account the stochastic processes for earnings and interest rates. Our analysis differs from past research of this type in being applicable to stocks that have a positive probability of zero or negative earnings. By avoiding the singularity at the zero point, our earnings‐based pricing model achieves improved pricing performance. The out‐of‐sample pricing performance of the generalized earnings valuation model (GEVM) and the Bakshi and Chen pricing model are compared on four stocks and two indices. The generalized model has smaller pricing errors and greater parameter stability. Furthermore, deviations between market and model prices tend to be mean‐reverting using the GEVM model, suggesting that the model may be able to identify stock market misvaluation.
