Inflation Risk?

Intereconomics - Inflation is on the rise again in the industrialised world. This has led to fears of a sustained surge in inflation. This article argues that while such fears may make sense in the...     

Entrepreneurial orientation and innovation in family SMEs: Unveiling the (actual) impact of the Board of Directors

Drawing on stewardship and resource dependence theories, we examine how the board of directors (BoD) influences the link between entrepreneurial orientation (EO) and ambidextrous innovation in small and medium sized family firms (family SMEs). Our analysis of 230 Spanish family SMEs shows that family involvement in the BoD has a negative effect on their ability to turn EO into innovation. Moreover, we show that the BoD's strategic involvement in service and control tasks and the provision of knowledge and skills have positive effects, whereas the intensity of BoD activity has a surprisingly negative effect. These findings underscore that the effects of the BoD on the entrepreneurship-innovation link are more complex than previously thought, pointing to the important role of both BoD composition and BoD functioning for enabling innovation in family SMEs.     

服务型领导对辱虐管理的作用机制——基于道德许可理论的视角

以利他、服务和谦卑为特征的服务型领导受到学界的广泛关注,但服务型领导在"暖心"行为后从事的偏差行为却较少得到重视.基于道德许可理论,采用多时点配对数据进行统计分析,结果表明,服务型领导通过心理权利的中介作用对辱虐管理产生正向影响,领导行为一致性是服务型领导催生辱虐管理的"门阀":当领导行为一致性较高时,服务型领导会滋生更多的心理权利,产生更多的辱虐管理;当领导行为一致性较低时,服务型领导通过心理权利产生的辱虐管理相对减弱.研究结论对于全面认识服务型领导理论和预防服务型领导的负面效应具有重要的参考价值.     

目的国服务贸易限制政策是否阻碍了中国企业出口规模扩张?

根据经合组织统计的各国服务贸易限制政策条款,先对具体政策条款赋值,接下来加权得到衡量服务贸易限制的STRI指标,最终检验目的 国服务贸易限制对中国企业出口规模的影响.研究发现:在控制引力模型的其他变量以及企业-产品层面的特征变量后,目的 国服务贸易限制政策显著阻碍了中国企业出口规模扩张,且阻碍作用对一般贸易企业、大中型企业更明显.对影响机制而言,服务贸易限制政策造成的固定成本阻碍了企业出口的扩展边际,而引起的可变成本阻碍了企业出口的集约边际,其中,对集约边际的阻碍作用更大;进一步对集约边际分解发现,目的 国服务贸易限制政策降低了企业出口产品数量,但提高了企业出口产品价格.另外,拓展研究发现,目的 国数字化服务贸易开放能够缓解服务贸易限制政策对企业出口的阻碍作用.     

An Empirical Analysis of Entrant and Incumbent Bidding in Road Construction Auctions

This paper explores differences in the bidding patterns of entrants and incumbents in road construction auctions. We find that entrants bid more aggressively and win auctions with significantly lower bids than incumbents. The differences in their bidding patterns are consistent with a model of auctions in which the distribution of an entrant's costs exhibits greater dispersion than that of an incumbent's and relations of stochastic dominance in the distributions do not persist for the entire range of estimated costs. We also find that more efficient firms bid, on average, more aggressively and firms with greater backlogs bid less aggressively.

Intraday Lead-Lag Relationships Between the Futures-, Options and Stock Market

In rational, efficiently functioning and complete markets, returns on derivative and underlying securities should be perfectly contemporaneously correlated. Due to market imperfections, one of these markets may reflect information faster. The use of high-frequency data and the choice for a small unit time interval to measure these lead-lag relations comes at the cost of some or many missing observations, causing traditional estimators to either under- or overestimate covariances and correlations. We use a new estimator to estimate lead-lag relationships between the cash AEX index, options and futures. We find that futures returns lead both options and cash index returns by approximately 10 minutes. The relationship between options and the cash market is not completely unidirectional.     

Information styles of marketing and R&D personnel during technological product innovation projects

Abstract The research question in the present article can be phrased in the following way: what are the elements which influence the perception of the utility of information received from another function? A field study research has been conducted in 40 Belgian companies. In each company, we have studied two on-going innovation projects (one planning project, one development project). Crossfunctional communication behaviours at the R&D/marketing interface have been measured by means of mailed structured questionnaires. Three-hundred and eighty-six questionnaires have been returned. The data analyses show that there are four underlying information dimensions, i.e. the perceived relevance, the perceived comprehensibility, the perceived novelty and the perceived credibility of information. We also discuss some contingency variables (function of the message receiver, stage in the innovation process) that might moderate the impact of these dimensions. It will be shown that the interaction between source and receiver has a significant impact on the perceived credibility, the perceived comprehensibility and the perceived novelty of the received information.
