Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

This study empirically examines the relation between profitability and liquidity, as measured by current ratio and cash gap (cash conversion cycle) on a sample of joint stock companies in Saudi Arabia. Using correlation and regression analysis the study found significant negative relation between the firm’s profitability and its liquidity level, as measured by current ratio. This relationship is more evident in firms with high current ratios and longer cash conversion cycles. At the industry level, however, the study found that the cash conversion cycle or the cash gap is of more importance as a measure of liquidity than current ratio that affects profitability. The size variable is also found to have significant effect on profitability at the industry level. Finally, the results are stable over the period under study.

The purpose of this study is to investigate the link between informal learning and employees’ in-role performance and whether the mechanism through informal learning mediates the relationships between self-efficacy, job characteristics, trust and in-role performance.

Based on data (n = 294) obtained from the firms with the Work–Learning Dual System in South Korea, a structural equation modeling (SEM) analysis was conducted.

The findings indicated that trust and job characteristics affected informal learning and informal learning mediates the relationships of trust and job characteristics with job performance.

The significant contributions of this study to the extant literature on informal learning are as follows: first, the present study investigates a mechanism and a mediating role of informal learning using SEM, while most previous studies in literature have employed qualitative research in informal learning. Second, this study explores the mediating role of informal learning between personal/job-related determinants of informal learning and in-role performance, which has not yet been examined in existing literature. Finally, this study provides practical implications regarding how organizations can facilitate more informal learning among employees to enhance their performance.

This paper aims to study the effects of perceived organizational support (POS) on employees’ knowledge sharing intention (KSI). More specifically, this study examined whether these effects are moderated by job characteristics (JCs) and are mediated by organizational citizenship behavior (OCB).

Data for 426 employees were collected via an online questionnaire from four IT companies in South Korea. Combined effects in the variable set were analyzed using conditional process analyses (Hayes, 2013).

The results indicate that POS positively affects OCB and KSI, and that JCs moderate the relationship between POS and OCB. Also, the relationship between POS and KSI is mediated by OCB, and the hypothesized moderated mediation model is confirmed.

This study is novel in empirically establishing how employees’ KSI is affected by POS as an integrative construct bringing together JCs and OCB. This paper intends to fill a methodological gap and nurture future research by adopting conditional process analyses assessing whether JCs moderate the relationship between POS and OCB and mediate the effects of OCB on KSI.
