The Small Business Capital Market Behavior in Athens Stock Exchange

Financing small and medium enterprises (SMEs), especially business investments and growth, is a composite and particular complicated affair in the Greek entrepreneurial reality. This paper examines the significance of secondary capital markets, as an alternative source of financing small-medium enterprises’ new entrepreneurial plans. Cointegration technique is applied to test the relationship between the secondary capital market and the dominant sectors in Athens Stock Exchange (ASE). Causality tests are also used to provide evidence on the existence of interdependence between the cointegrated series. The results indicate that there is significant uni-directional causality between primary and secondary capital market in Greece, enhancing us to suggest valuable policy implications.      

A conceptual framework of anonymity in Group Support Systems

As the development and use of automated systems for collaborative work grows, the need for a better understanding of these systems becomes more important. Our focus is on one type of system, a Group Support System (GSS) and, in particular, on one important aspect of a GSS—anonymity. A conceptual framework for the study of anonymity in a GSS is presented, which describes the general classes of variables and their relationships. These variables include the factors that influence anonymity in a GSS, types of anonymity, and the effects of anonymity on a message sender, receiver, group process, and outcome. Each of these variables is discussed with working propositions presented for important group process and outcome measures. The objectives of this article are to highlight the importance and complexity of anonymity, to act as a guide for empirical investigations of anonymity, and to influence future GSS development and use.

Analysts' Forecasts and the Broker Relationship

Analysts' ability to forecast earnings per share has been the subject of considerable debate. A concern highlighted in previous research is the agency problem which may arise when analysts have a close working relationship with the firms for which they are providing forecasts. This paper provides evidence that this relationship does not improve the accuracy of the earnings forecasts, but stimulates optimistic forecasts. In addition, the paper examines whether firm size is a factor in forecast accuracy or bias.
