We investigate whether inclusion and permanence in the Domini social index affects corporate performance on a sample of around 1,000 firms in a 13-year interval by controlling for size, industry, business cycle and time invariant firm idiosyncratic characteristics. Our results find partial support to the hypothesis that corporate social responsibility is a move from the shareholders wealth to a multistakeholders welfare target. On the one side, permanence into the Domini index is shown to increase (reduce) significantly total sales per employee (returns on equity but not when large and R&D investing firms are excluded from the sample). On the other side, lower returns on equity for Domini firms seem nonetheless to be accompanied by relatively lower conditional volatility and lower reaction to extreme shocks with respect to the control sample. An explanation for these findings, suggested by the inspection of Domini criteria, is that social responsibility implies, on the one side, decisions leading to higher cost of labour and of intermediate output, but may, on the other side, enhance involvement, motivation and identification of the workforce with company goals with positive effects on productivity.Key words: social responsibility, stakeholders, corporate performance.

A 'two-stage growth' discounted cash flow (DCF) model is built to test whether changes in the underlying market fundamentals help to explain movements in stock prices. Empirical results on two samples of US and EU stocks show that the 'fundamental' earning price ratio (E/P) explains a significant share of cross-sectional variation of the observed E/P, this impact being stronger in the US market. It is also found that: (i) the fundamental component of the E/P has superior explanatory power than simpler measures of expected earnings growth; (ii) 'non-fundamental' components, interpreted as signals reducing asymmetric information (such as firm size, the number of forecasts and the chartist momentum), mitigate the role of the fundamentals; (iii) current deviations from the fundamentals are affected by ex post adjustment of publicly available information in the EU sample. It is argued that differences in regulatory environments and in the composition of investors between the US and EU financial systems may help to explain these comparative findings. Results appear consistent with the 'market integrity hypothesis' postulating that reliance on publicly observable fundamentals is higher when insider trading is lower.DCF fundamental value, price earning ratio, non-fundamental components, asymmetric information, insider trading,

We analyse the effects of information and communication technology (ICT) on levels and growth of per capita GDP in two different ways: (1) by treating ICT as a specific type of physical capital and as a variable that helps to correct for quality existing physical capital measures, and (2) by considering that telephone lines, personal computers and internet hosts are 'bottleneck-reducing' factors that increase the productivity of labour by making easier the diffusion and processing of (non-rivalrous and almost non-excludable) knowledge. We compare the relative significance of the two hypotheses in level and growth estimates and find that, when separately taken, both of them improve upon the classical Mankiw et al. framework. These findings show that our approach captures dimensions of time-varying country-specific technological progress that previous approaches in the literature did not take into account.
