Each new issue of our journal contains articles that have been sent to the editorial board and, following the reviewing procedure, accepted for publication. As we do not invite the authors to choose a specific subject, these articles in some sense provide an answer to the question: what topics in financial sciences were in the past few months recognized as the most interesting for the scientific community? When we look at the contents of this volume, it seems that in public and corporate finance an important problem is the appropriate measurement of the effects resulting from public expenditure (the first three articles). Concerning the financial markets, the instrumental approach dominates, where scientists (the authors of the next four articles) seek to present some new, useful tools to operate in these markets. We hope that the contents of this volume will give both information and inspiration to lectu¬rers.
