| Abstract: | As the information load grows, it becomes increasingly difficult to follow-up new trends in business and management. However, new developments in technologies and markets pose threats and open up opportunities to firms. Especially the software business changes continuously and profoundly. It is therefore necessary for researchers and practitioners to follow up recent developments and to cope with the information overload. We suggest the application of a data mining technique in order to automatically identify topics: Latent Dirichlet Allocation (LDA). Using a sample of 13,799 publications from ICSOB and major conferences on Information Systems, we identify topics relevant to industry transformation research and review their development on a timescale. As proof of concept, we conduct a short case study using Green IT in order to demonstrate that topic analysis can yield relevant results for literature search beyond the results that can be obtained through a simple keyword search. |

| Abstract: | Policy programs on anti-money laundering and combating the financing of terrorism (AML/CFT) have largely called for preventive measures like keeping record of financial transactions and reporting suspicious ones. In this survey study, we analyze the extent of global money laundering and terrorist financing and discuss the preventive policies and their evaluations. Moreover, we investigate whether more effective tax information exchange would bolster AML/CFT policies in that it reduced tax evasion, thus the volume of transnational financial flows (i.e. to and from offshore financial centres) and thus in turn cover given to money laundering and terrorist financing. We conclude that such a strategy can reduce financial flows, yet due to a "weakest link problem" even a few countries not participating can greatly undo what others have achieved. |

| Abstract: | The asset allocation of university endowments has recently shifted dramatically towards alternative investments. In this paper we examine the role played by strategic competition in motivating this shift. Using a metric capturing competition for undergraduate applications, we test whether endowment performance relative to a school’s nearest competitor is associated with the likelihood of changing investment policy, and conditionally, whether the nature of that change is consistent with the goal of “catching up” to its closest rival. Conditional on indicating a policy change, we find that endowments appear to use marketable alternatives – i.e. hedge funds – to catch up to competitors. More generally, we find evidence that endowments with below median holdings of alternative investments tend to shift policies in that direction. Besides herding behavior we also find trend-chasing behavior. Endowments with recent positive experience with various alternative asset classes tend to increase exposure to them. We consider the long-run implications of this competitive and trending behavior for the ability of endowments to deliver intergenerational equity. |
