We use a unique firm-level data set including 9000 companies from 26 European Union countries covering four different sectors to take a close look at the relationship between online exports and productivity. The online exporter productivity premium is estimated using different techniques (ordinary least squares, quantile regressions and robust estimation). Results consistently indicate that the estimated online exporter productivity premium is statistically different from zero, positive and significant from an economic point of view. European online exporters, according to these results, are approximately 2% more productive than non-online exporters. Productivity differences between firms could be related to variables that are not included in the empirical model. More research would be needed to address this issue in the future.  相似文献

Measuring volatility with the realized range   总被引:1,自引:0,他引:1  
Realized variance, being the summation of squared intra-day returns, has quickly gained popularity as a measure of daily volatility. Following Parkinson [1980. The extreme value method for estimating the variance of the rate of return. Journal of Business 53, 61–65] we replace each squared intra-day return by the high–low range for that period to create a novel and more efficient estimator called the realized range. In addition, we suggest a bias-correction procedure to account for the effects of microstructure frictions based upon scaling the realized range with the average level of the daily range. Simulation experiments demonstrate that for plausible levels of non-trading and bid–ask bounce the realized range has a lower mean-squared error than the realized variance, including variants thereof that are robust to microstructure noise. Empirical analysis of the S&P500 index-futures and the S&P100 constituents confirms the potential of the realized range.  相似文献

在本文中,我们验证了这样一种假设,即:在欧洲全球化水平较高的国家和全球化水平较低的国家当面对经济危机时,同样脆弱。我们用马斯特里赫特全球化指数(MGI)来界定各国的全球化水平,用五个关键的经济指标来衡量经济危机的严重程度。结果表明:一方面,全球化水平的提升增加了国家面对经济危机时的脆弱性;另一方面,较高的全球化水平也增加了解决危机的机会。  相似文献

The growing body of literature on “accessible tourism” lacks a critical scholarly debate around its specific language use and nomenclatures. To fill this gap, this paper provides a first examination of language. Language provides a unique capability to resist, strengthen and reframe identities of individuals and groups, yet can also reinforce, weaken and perpetuate dominant worldviews of disability. A content analysis examined previous accessible tourism literature with results illustrating that diversity exists amongst the varying terminologies adopted by scholars. Terms were employed loosely, inconsistently and interchangeably, euphemistically with erroneous understandings and nuances. The paper concludes with critical discussion about the power of researchers to (re) produce oppression through language that maligns and misrepresents, or to (re) conceptualise and (re) construct the world we live in with liberating language that facilitates positive social change.  相似文献

Democracy seems to be at risk. People elect populists and autocrats, who offer simple solutions to social problems. Often, these problems are not even real ones but are only perceived as such. Economists have measures to determine which problems are fact-based, but they cannot draw a clear distinction between academic analysis and normative demand. If politics pursues a correction of a market outcome, any normative criteria other than efficiency have to be outlined explicitly. Nevertheless, some authors consider inequality one of the central contemporary social and economic challenges. Marcel Fratzscher emphasises that the solution is not found in more redistribution via taxes and transfers, but rather through greater equality of opportunity and social and educational mobility. Bert Rürup thinks that to stabilise the acceptance of the compulsory pension scheme, the dominance of the equivalence principle should be reduced. Further, the existence of different federal subsidy schemes should be replaced by a fixed federal contribution rate in alignment with the pension expenditures. In an international comparison, the fiscal burden for households with small and mid-level earned incomes is exceptionally high in Germany. In order to reduce this burden, Rürup suggests a contribution-free allowance for the social insurance contributions.  相似文献

Although frontline employees' bending of organizational rules and norms for customers is an important phenomenon, marketing scholars to date only broadly describe over-servicing behaviors and provide little distinction among deviant behavioral concepts. Drawing on research on pro-social and pro-customer behaviors and on studies of positive deviance, this paper develops and validates a multi-faceted, multi-dimensional construct term customer-oriented deviance. Results from two samples totaling 616 frontline employees (FLEs) in the retail and hospitality industries demonstrate that customer-oriented deviance is a four-dimensional construct with sound psychometric properties. Evidence from a test of a theoretical model of key antecedents establishes nomological validity with empathy/perspective-taking, risk-taking propensity, role conflict, and job autonomy as key predictors. Results show that the dimensions of customer-oriented deviance are distinct and have significant implications for theory and practice.  相似文献

Prior to 1996, the Australian system of advertising self-regulation was regarded as a world model and many Asia-Pacific systems included components adapted from the Australian system. The recent changes to this system, encouraged by the abolition of the media accreditation system, consumer association pressure, criticism from the national advertisers association and the lack of a strong advertising agency presence, present an interesting framework in which to review the foundation concepts of self-regulation in advertising. This paper compares the new code of ethics with its predecessor and an international standard. It examines the performance of the code in terms of the number of complaints upheld and complaint by medium and product type and the voluntary response of advertisers. The findings suggest a weakening in the standard of advertising self-regulation in Australia, with fewer provisions in the Code of Ethics, a significantly fewer number of complaints upheld and no real power of enforcement. Although the case is Australian, it raises universal questions such as the vested interest of advertisers in controlling the process and roles of the consumer association, the media and the advertising agencies in guaranteeing the privilege of self-regulation.  相似文献

This study revisits current practice that ownership holding at IPO has a homogeneous impact on IPO performance. Using signalling theory, we develop and test a conceptual model explaining the relationships between the aggregated ownership structure and IPO price premium. We argue that aggregated ownership has a direct effect on issue price premium, and offer specific hypotheses on the effect of the shares sold during the offering by each type of owner on IPO performance. We use archival data from a sample of US firms that issued IPOs between 1996 and 2000 and find a significant direct effect of ownership configuration, namely, heterogeneity in effect of each ownership type on IPO performance as well as interaction effects between different ownership types.

Astroturf organizations are fake grassroots organizations usually sponsored by large corporations to support any arguments or claims in their favor, or to challenge and deny those against them. They constitute the corporate version of grassroots social movements. Serious ethical and societal concerns underline this astroturfing practice, especially if corporations are successful in influencing public opinion by undertaking a social movement approach. This study is motivated by this particular issue and examines the effectiveness of astroturf organizations in the global warming context, wherein large corporate polluters have an incentive to set up astroturf organizations to undermine the importance of human activities in climate change. We conduct an experiment to determine whether astroturf organizations have an impact on the level of user certainty about the causes of global warming. Results show that people who used astroturf websites became more uncertain about the causes of global warming and humans’ role in the phenomenon than people who used grassroots websites. Astroturf organizations are hence successful in promoting business interests over environmental protection. In addition to the multiple business ethics issues it raises, astroturfing poses a significant threat to the legitimacy of the grassroots movement.  相似文献
