Despite the significance of economic value indicators in the measurement of firm value, not much attention has been dedicated to how research and development (R&D) influences firms’ economic value. This study examines the relationship between R&D investments and firms’ economic value and considers the moderating role of age in the relationship using a dataset from manufacturing and information and technology firms in China. The results show that R&D investments impact firms’ economic value positively. This suggests that firms that invest in R&D are rewarded with a monopoly, which increases their market shares, thereby increasing economic value. Again, we find that older firms increase their economic value more than younger ones when they both invest in R&D. Thus, younger firms in China suffer from the liability of newness when they invest in R&D. It is recommended that these younger firms should strive to shorten the time to reap the returns from R&D investments.
Real estate indices based on appraisals or sale prices of properties are known for their slow response to market news. These indices can therefore be represented (in logarithm) as the sum of a latent "true" price index and a lagging error. We show that the latent appreciation return and the lagging error can be jointly estimated in a state–space model, which has two key features. First, it employs exogenous variables known to predict asset returns to predict the latent appreciation return. Second, it incorporates known sources of the lagging error, such as the partial adjustment in observed index to the latent appreciation return and the seasonality in reappraisal quality. We find that, after the estimated lagging errors are removed, the appraisal–based National Council of Real Estate Investment Fiduciaries returns become more informative and hence exhibit (i) greater variance, (ii) weaker auto correlation, (iii) higher correlation with the returns of the securitized real estate and (iv) more timely response to market news. 相似文献
