The ancient olympics as a signal of city-state strength

Ancient Greece was wealthy enough to invent many of the foundations of Western Civilization. In order to accomplish this, they had to avoid the trap of dissipating wealth through continuous feuding. We contend that the ancient Olympics was one, of several, institutions that helped achieve this by acting as a signal of city-state strength. Although it could not prevent all battles, it provided information to reduce hostilities between competing cities. This hypothesis explains the rise and fall of the Olympics, and the unique and puzzling characteristics of the rules and events.     

‘Thinking Before Acting’ or ‘Acting Before Thinking’: Antecedents of Individual Action Propensity in Work Situations

We introduce the concept of ‘individual action propensity’ to examine the approach of individuals towards solving situations for which they lack knowledge and/or experience about what to do. We focus on a naturally contrasting pair of responses: ‘thinking before acting’ or ‘acting before thinking’, and associate low action propensity with thinking one's way into understanding how to act, and high action propensity with acting one's way into understanding such situations. We build on regulatory mode theory – with its dimensions of locomotion and assessment and the trade‐off between speed and accuracy – to examine individual characteristics as predictors of individual action propensity. We find that individual action propensity is associated with being a woman, having fewer years of formal education, not relying on help‐seeking behaviours, and having a positive attitude towards spontaneity. Our findings shed light on why individuals take action, or not, and provide implications for research on organizational action propensity.     

Understanding the effect of market orientation on circular economy practices: The mediating role of closed-loop orientation in German SMEs

The implementation of circular economy (CE) practices is considered a key driver towards sustainable development of firms. Earlier studies point to the general strategic approach of market orientation as an antecedent to CE practice implementation. Still, insights are limited as the mechanisms underlying this relationship remain unclear. Based on a sample of 121 German small and medium-sized enterprises (SME), we empirically examine how the strategic approach of closed-loop orientation mediates the relationship between market orientation and the implementation of three types of CE practices. Using structural equation modelling, we find that while market orientation is positively related to all three types of CE practices, closed-loop orientation mediates these relationships for only two. Our study extends CE literature by suggesting that market orientation is translated into closed-loop orientation to spur CE practice implementation. We also offer a differentiated understanding of CE practice implementation in the context of German SMEs.     

Citations,journal ranking and multiple authorships reconsidered: evidence from almost one million articles

In this article, we reconsider the investigation by Moosa (2016) using a much larger data set of almost one million articles listed in Research Papers in Economics. This article provides new insights into the effects of co-authorship on citation counts and the correlation between quality of papers and quality of the publishing journal. Our evidence is partially in contrast to the results reported in Moosa (2016). We find a positive correlation between the h-index of a journal and the quality of papers measured in terms of citations. This correlation becomes almost perfect using a nonlinear model. Results from a regression of citation counts on the number of authors show evidence of a positive and significant effect of co-authorship on the quality of a paper when time effects and large sets of top-cited articles are taken into account. The inclusion of time effects and the large data set, that allows to differentiate between top-cited cohorts, adds further insights to the existing literature.     

Purchasing power parity in Brazil: a test for fractional cointegration

The purpose of this paper is to test the validity of the purchasing power parity (PPP) doctrine in Brazil. Historical data for the period 1855–1996 are considered. The period 1855–1990 is also analysed in order to compare the results with those obtained by Zini and Cati (1993) using the conventional cointegration analysis. This article uses fractional cointegration analysis, a flexible methodology which allows for more subtle forms of mean reversion. The tests performed are those of Geweke and Porter-Hudak (1983), and of Hurvich and Ray (1995). The critical values for both tests are generated by simulation because they are non-standard. The empirical results do not support the absolute PPP hypothesis but the relative PPP holds in the long run.     

Reformbedarf bei der steuerlichen Berücksichtigung von Kinderbetreuungskosten

In Germany, parents’ taxable income base is reduced by the costs of childcare. The way this is done at the moment is not suitable: for some parents, the income tax deduction is too high, while for others it is too low. The actual tax regulations concerning childcare costs do not support the ability-to-pay principle. This paper discusses how the costs of children and childcare should be treated for tax purposes and which reforms would improve the fairness of the tax treatment of taxpayers with children compared to the tax treatment of taxpayers without children.     

Two are Better Than One: The Link Between Management Systems and Business Performance

Little is known about the complementary performance benefits associated with facilities’ combined use of both quality management systems (QMSs) and environmental management systems (EMSs), and how these performance benefits might differ from those associated with facilities’ use of only one of these management systems (or neither). We suggest that complementarities arise because each management system fosters the development of internal capabilities that facilitates the adoption and routine operationalization of the other, while maintaining differentiated goals that enhance strategic value. We examine these relationships using a sample of 2619 manufacturing facilities operating within six OECD countries, while controlling for self‐selection issues. Our findings support the idea of complementarity, in that facilities that adopt both QMS and EMS are more associated with positive business performance than facilities that adopt either a QMS or an EMS on its own, or no management system.

The evolution of cognitive radio technology in Europe: Regulatory and standardization aspects

Cognitive radio (CR) is considered a promising technology that could provide important benefits in the telecommunication domain. In Europe, the number of research projects, standardization activities and public consultations by the European Commission and regulatory authorities testify to the growing interest in CR. The introduction of CR in the telecommunication market may require new regulations or changes to the way spectrum is licensed and the conditions under which it can be used. The concepts of CR can be applied to various operational scenarios, which are described in this paper.This paper identifies the main challenges for the deployment of CR technology in Europe, provides an overview of the activities by European regulatory and standardization bodies to address the identified challenges and describes a roadmap with potential actions to support the adoption of CR technology.     

Private Equity Fair Value Measurement: A Critical Perspective on IFRS 13

In this paper, we discuss IFRS 13 Fair Value Measurement with regard to private equity valuation. We raise issues on the fair value definition as an exit price and question the reliability of valuation techniques, which are categorised into Level 2 fair value hierarchy. Our paper questions whether fair value as defined by IFRS 13 is an appropriate measure for private equities and can contribute to enhancing transparency and comparability in financial statements, which is one of the purposes of the International Accounting Standards Board and the European Union Regulation 1606/2002.     

Do Employers Respond to the Costs of Continued Search?*

An analysis of US and Slovenian vacancy data sets reveals that an employer who is searching to fill a job vacancy is more likely to fill the vacancy by hiring an under‐qualified worker when the search costs are higher; when, at the start of the search, the employer has less time to search at low cost; and during the week following an increase in search costs. These are interesting findings not only about the effects of search costs on employers’ hiring decisions, but also because they suggest that search frictions in the two labour markets may be considerable.
