This study tests the value relevance of R&D expenses for the Portuguese context. The methodology adopted is based on econometric models, and takes into consideration the kind of information companies display and the adoption of IASB accounting standards in 2005. The empirical evidence suggests...

This study investigates the extent to which three key summary accounting income figures, namely operating income (OPI), net income (NI) and comprehensive income (CI), provide value-relevant information to investors in major EU capital markets. Using a large sample over the pre-IAS-compliance...

This paper develops an empirical approach using econometric techniques for panel data which aims to contribute to the reduction/elimination of the deviation between the book and market value of firms. Based on 20 of the firms with the largest number of patents granted between 1996 and 2006, the...

In an earlier paper (Los, 1998a), the exact and complete return attribution framework of Singer and Karnosky (1995) was extended to include market risk measurements for n countries. Exploiting a selection matrix based on the cash accounting identities, the resulting degenerate portfolio choice...

The business media play an active role in influencing stock prices. Statistically significant excess returns at the time of the publication of stock recommendations have been documented many times. Frequently these abnormal gains begin to accumulate long before the publication date. In most...

A widely held belief in financial economics suggests that stock prices always adequately reflect all available information. Price movements away from fundamentals are assumed to occur only infrequently, if at all. „False“ prices are supposed to be corrected by the counter-actions of...
