This article presents the results of a study that analysed whether social responsibility had any bearing on the decision making of institutional investors. Being that institutional investors prefer socially aligned organizations, this study explored to what extent the corporate actions and/or social/environmental investments influenced their decisions. Our results suggest that there are specific variables that affect the perceived value of the organization, leading to decisions to not only invest, but whether to hold or sell the shares, and therefore having a (...) consequential impact on the capital market’s valuation.

In this note we consider register-machines with symbol manipulation capabilities. They can form words over a given alphabet in their registers by appending symbols to the strings already stored. These machines are similar to Post's normal systems and the related machine-models discussed in the literature. But unlike the latter devices they are deterministic and are not allowed to read symbols from the front of the registers. Instead they can compare registers and erase them. At first glance it is surprising that (...) in general these devices are as powerful as the seemingly stronger models. Here we investigate the borderline of universality for these machines. (shrink)
