What determines IPO underpricing ? Evidence from a frontier market

This paper empirically analyzes the short run performance of Tunisian initial public offerings (IPO). It sheds light on the determinants of IPO’s in a context of a frontier market characterized by high information asymmetry, low information efficiency, thin trading and the presence of “noise” traders. Using a sample of 34 Tunisian IPO’s from the period 1992-2008, we find that the average market adjusted initial return for the first three trading days is about 17.8 percent. The level of underpricing is related to retained capital, underwriter’s price support, oversubscription, listing delay and the offer price. Age of the firm, its size and the size of the offer do not seem to reduce the amount of money left on the table by issuers. It appears also that underpricing is driven by irrational investors (ipoers) seeking for short-run capital gains. These results remain unchanged after controlling for the presence of institutional investors and the existence of liquidity contract.Initial public offerings; Short-run underpricing; Underwriter’s price support.

Auditor selection of negotiation strategies : the effect of motivational factors and bargaining power under a throughput model

Motivational factors and bargaining power have been recognized by scholars and practitioners alike, as important elements for negotiation strategies. However, there has been little effort to date to empirically or theoretically study the effect of these factors in the context of auditor-client negotiation while adopting a decision-making process framework. We present a Throughput Model framework that describes the decision-making process of auditors when they make decisions about negotiation strategies. The model depicts how (a) perception of motivational factors and (b) bargaining power affect the choice of negotiation strategy and identifies different pathways auditors use in their decision about negotiation strategies.In our experiment, we manipulate engagement risk perception, client pressure, corporate mechanisms strength as well as financial information. We. investigate their effects on auditor decision making about the likelihood of accepting client's management alternative and on the negotiation strategies choice. We find that only engagement risk perception influences auditor's propensity to accept aggressive accounting treatments of the client. This in turn influences the use of all the negotiation strategies. On the other hand, client pressure only has effect on compromising strategies while bargaining power influences the concessionary strategy of auditors. Moreover, two dominant decision making pathways are used by auditors, i.e. P→J→D and P→D

Modeling e-Business with eBML

In this paper we demonstrate that modeling e-business strategies is important in a time where the first e-business disillusionment has taken place. The objective of this Paper is twofold. First we propose a theoretical e-business model framework (eBMF) for aligning e-business initiatives and projects. This framework rep-resents an ontology, which will allow firms to develop a sound e-business model, in an environment that is amongst other things characterized by new forms of network organizations. Second we show why the eX-tensible Markup Language (XML) is an adequate technology for describing this theoretical framework in a formal way.xml, e-business models, e-business

Questioni pregiudiziali: una prospettiva epistemologica sui rapporti tra neuroscienze e diritto

In the last few years the problem of the influence of neuroscientific research on the juridical world has enjoyed a huge amount of interest, though the “neuroscience vs law” approach is sometimes unfold without a previous clarification of the conditions and the limits that permit a legitimate comparison between speeches and social practices (those under the general lables “sci-ence” and, respectively, “law”) originated and conducted within theoretical paradigms so dis-tant. In other words, very often the juxtaposition between “neuroscience” and “law”, as well as the speculations built on it, are led leaving unexpressed definitions and theoretical presupposi-tions about the concepts of “law” and “science” employed, trusting on a share of intuitive com-mon places about something which has been considered “essentially contested” instead. Thus, the aim of this paper is twofold: first, I will critically espose some epistemological issues emerged at the turn of the XX century, focusing on some reactions to the relativistic turn based on the (re-)discovery of the importance of the experimental side of every scientific enterprise. In my opinion, those proposals have given important insights that can help the clarification of a le-gitimate “scientific riductionism”; then, on those epistemological grounds, I will try to set the stage for a profitable discussion about the extra-theoretical use of scientific propositions, in par-ticular of those generated within current neuroscience researches to deal with specific juridical problems
