  1. By: Chang, C-L.; McAleer, M.J.; Wong, W.-K.
    Abstract: This paper provides a review of some connecting literature in Decision Sciences, Economics, Finance, Business, Computing, and Big Data. We then discuss some research that is related to the six cognate disciplines. Academics could develop theoretical models and subsequent econometric and statistical models to estimate the parameters in the associated models. Moreover, they could then conduct simulations to examine whether the estimators or statistics in the new theories on estimation and hypothesis have small size and high power. Thereafter, academics and practitioners could then apply their theories to analyze interesting problems and issues in the six disciplines and other cognate areas.
    Keywords: Decision sciences, economics, finance, business, computing, and big data, theoretical models, econometric and statistical models, applications

    Abstract: The purpose of the paper is to present arguments for and against the use of the Impact Factor (IF) in a rapidly changing digital world. The paper discusses the calculation of IF, as well as the pros and cons of IF. Editorial policies that affect IF are examined, and the merits of open access online publishing are presented. Scientific quality and the IF dilemma are analysed, and alternative measures of impact and quality are evaluated. The San Francisco declaration on research assessment is also discussed.

    Abstract: We investigate whether the returns to mobile information and communication technology (ICT) in the workplace are contingent on granting employees autonomy over the structure of their workday through trust-based work time arrangements (TBW). Our regression analysis is based on a production function framework and exploits fine-grained firm survey data on ICT use and organisational practices for 1,045 service firms in Germany. We find empirical support for the argument that the returns to mobile ICT are higher when TBW allows for discretion over when, where and how to perform work-related tasks. The finding holds when we account for more limited forms of workplace flexibility, suggesting that the high degree of formal employee autonomy under TBW drives the complementarity between mobile ICT and organisational practices.

    Abstract: This paper provides evidence on the impact of fast Internet on firm performance in developing and transition economies. Over the last three decades, international connectivity has been boosted by the laying of more than 300 submarine telecommunications cables (SMC). Almost all coastal developing and transition countries are plugged into the global Internet, so the remaining structural impediments to the Internet economy’s growth are twofold: first, the digital isolation induced by the distance of Internet users from key telecommunications infrastructures; and second, the country’s exposure to SMC outages. We therefore adopt an instrumental variable (IV) approach reflecting these two sources of digital vulnerability. Exploiting the hierarchical structure of the World Bank Enterprise Survey dataset, multilevel IV estimations are conducted on a large sample of firms from more than 2,600 locations in some 60 developing and transition countries. They stress the large local impacts of an increase in the local incidence of email use by firms, induced by a lesser digital vulnerability, on a firm’s average annual sales and sales per worker, and, to a lesser extent, on temporary employment. Estimated relationships are robust across a range of alternative sampling and specifications.
