Audit opinion and earnings management: Evidence from Greece

This study examines the relationship between audit opinions and earnings management, as measured by discretionary accruals, for listed firms on the Athens Stock Exchange (ASE). We divide the qualified audit opinions into two categories: qualified for the going-concern uncertainty and qualified for other reasons. The results indicate that audit opinions are not related to earnings management. Client financial characteristics, such as profitability and size are determinants of the going-concern audit opinion decision. The decision of auditors to issue qualified opinions for other reasons is explained by the type of audit opinion issued in the previous year.     

The coopetition paradox and tension in coopetition at multiple levels

This article explores the nature of the paradox inherent in coopetition; that is, the simultaneous pursuit of cooperation and competition between firms, and emanating tensions that develop at individual, organizational, and inter-organizational levels. We dissect the anatomy of the coopetition paradox to discover how it materializes by creating an external boundary (i.e., via unifying forces) and internal boundaries (i.e., via divergent forces). After explaining the coopetition paradox, we distinguish tension from paradox and submit that tension comprises both positive and negative emotions simultaneously, also known as emotional ambivalence. Finally, we recognize that emotional ambivalence in coopetition prevails at different levels, and vary in its level of intensity and persistency in relation to different contexts. We employ illustrative cases to ground our propositions empirically. This article provides understanding on concepts, expects to incite fruitful dialogue, and fuels further studies on inter-firm paradoxes.     

How Should Customers Be Integrated for Effective Interorganizational NPD Teams? An Input–Process–Output Perspective

Interorganizational new product development (NPD) teams with business customers are rapidly becoming more prevalent; yet the drivers of such cooperations at the team level remain unclear to practitioners and researchers alike. This study proposes an input–process–output model in which various characteristics of interorganizational teams affect NPD team effectiveness through the mediating construct of NPD team cooperation. Furthermore, various moderators, reflecting the supplier's dependence on the customers (customer power and customer participation) and the supplier's environmental uncertainty (market dynamism and technological turbulence), affect the strength of the underlying relationships. The results show that customer power positively affects the relationship between intrapersonal team characteristics and team cooperation. In addition, a negative moderation occurs in interpersonal characteristics. Customer participation exhibits opposing moderating effects. Regarding the supplier's environmental uncertainty, market dynamism and technological turbulence strengthen the relationships under consideration.     

Price assessments by consumers: influence of purchase context and price structure

Among the numerous factors that influence decisions on prices, consumer behaviour has special significance. This paper reviews and analyses relevant studies conducted during the last few decades. On the basis of our analysis, four categories of factors that determine consumer behaviour have been identified. Additionally, we have developed an experimental research design to analyse the influence that the following factors have on price perception: price structure (i.e. price level, order of presentation and price differences), purchase context (i.e. reason for purchase or product use) and demographic characteristics (i.e. gender). Results reveal a significant influence of these variables on consumer behaviour.     

Private-Law Instruments for Reduction of Risks on International Financial Markets: Results and Limits of Self-Regulation

International financial markets are characterized by self-regulation among private parties and international action in the regulation of such behavior. The Group of Seven plan, the World Trade Organization Agreements, the General Agreement on Trade in Services principles, and European Union Community Law provide a minimum standard of derivative transactions with the aim of reducing the risks related to those products. Codes of best practice are a source of regulation at an international level, but their effectiveness depends on their acceptance by the business firms operating in the markets. The role of self-regulation is very important; it can prevent and manage risk in an optimal way, under the condition of a harmonized international law. Public law has to manage the externalities that arise from private transactions, and private regulation has to make the rest.     

Aufmerksamkeit und Geld, schenken und zahlen

In recent years economic influences seem to have grown stronger in the media system. This general impression, however, is not supported by general systems theory. Analytically it is possible to distinguish a market trading attention from a market trading money. The interplay of both markets shows a different kind of interdependence between the media system and the economic system. The eminent importance of the market of attention and the far-reaching consequences for media economics are revealed. The latter is a promising area which should incorporate traditional mass media as well as new communication technologies such as the internet.     

Volatility behavior of exchange rate future contracts

The increasing globalization of economies and the concurrent increase in the risk of currency exposure has stimulated the development of new instruments to allow both investors and traders to hedge their currency risk. The expansion of these derivatives, however, has raised some concerns. This paper studies the determinants of the dynamics of exchange rate future contracts as a means to identify the sources of such concerns. By using a mean-exponential generalized autoregressive conditional heteroskedasticity (M-EGARCH) model for five different future contract lengths and six developed economies, it is found that an M-EGARCH(1,1) effectively describes the exchange rate futures' daily dynamic. Sign, size, and persistence effects on the volatility of future contracts are all significant, thus providing important information to both policy makers and market participants.
