Purpose This research specifies the factors impacting on the success of supply chain management (SCM) systems in the organizations. This paper aims to assess the effect of knowledge sharing, the vehicular ad hoc network (VANET), radio frequency identification technology (RFID) and near field communications (NFC) and the social capabilities of information technology (IT) and information and communication technology (ICT)on the success of the SCM systems and the simplification of the SCM challenges and other factors affecting its success. Design/methodology/approach A questionnaire is designed for measuring the elements of the proposed model. The questionnaires are revised by experts with experiences in SCM. For statistical analysis, SPSS 24.0 and SMART- PLS (partial least squares) 3.2.6 software package are used. The structural equation modeling (SEM) analysis procedure is conducted in two stages. The reliability analysis and confirmatory factor for analyzing the dimensions and items are included in the first stage. The second stage involves evaluating the assumptions through the SEM. Findings The results have depicted that four variables (knowledge sharing, VANET, RFID and NFC, and the social capabilities of using IT) affect the success of SCM systems. Originality/value This research specifies the factors impacting on the success of SCM in the organizations. These technologies aid companies in improving their performance in the SCM and facilitating coherence and collaboration.

Purpose The purpose of the present paper is to examine the trade-off relationship between managerial ownership and corporate debts and whether this relationship is moderated by ownership structure and corporate tax rates, particularly in a transition and emerging market whose unique institutional characteristics considerably differ from those prevailing both in the West and East markets. Design/methodology/approach This research is semi-empirical in terms of method and practical in terms of purpose. The authors test their hypotheses by using simultaneous equations system methodology with two- and three-stages least squares regression (2SLS and 3SLS) and panel data technics on a sample of 952 listed companies on the Tehran Stock Exchange during 2011-2018. Findings The findings indicate that, contrary to the current line of research, there is no trade-off relationship between managerial ownership and debt concerning the reduction of agency costs. Likewise, the study finds no convincing evidence that either the controlling shareholder or the corporate tax rate could influence or moderate this interrelationship. The conjecture lies in the fact that the fundamental environmental variations between the Tehran Stock Exchange and the institutional assumptions underpinning the Western models have led to the formation of such unexpected results. Research limitations/implications The implications drawn from this study are constrained by two primary limitations. First, the present study is conducted in an Iranian setting; therefore, the data used for the study only contain companies listed on the Tehran Stock Exchange. The utilization of listed companies on the Tehran Stock Exchange is likely to affect the generalizability of the study in an international context. Second, in this study, we were unable to extend the sample time period because of some major deficiencies in the Tehran Stock Exchange library and its supplementary software. The usage of an extended time period could have provided more generalizable results. However, extended time period, per se, may impair the validity of the results as well. Originality/value Because the fundamental institutional assumptions underpinning the Western and even East Asia capital structure models are not valid in the institutional environment of Iran, the findings of this study could provide substantial implications for the understanding of agency costs and capital structure literature. These significant institutional and ownership differences are the factors affecting firms’ leverage and capital choice decisions. Indeed, this study has laid some groundwork upon which a more detailed evaluation of the Iranian firms’ capital structure could be based. In addition, the examination of such relations may provide the ground for sound decision-making by various interested users of financial and accounting information.

PurposeIn recent years, rapid changes in the economic situation and high levels of competition have increased the need for innovation in order to gain success. In such circumstances, organizational strategists are considered as critical in determining the success or failure of organizations. Using innovation in various aspects of organizational operations is the most important factor to achieve sustainable competitive advantages in industry. As a result, analyzing the effective factors involved in promoting the efficiency of innovative activities in the organization and ways of achieving it are of utmost importance. Thus, this paper examines the relationship between communication and innovation performance with respect to the intermediary role of strategic decision-making process speed.Design/methodology/approachThe present study has used quantitative methodology and questionnaire to collect data from 450 managers and members who are involved in the decision-making process in 150 companies operating in the food-industry sector. Data analysis was done by using structural equation modeling and AMOS software.FindingsThe results of the data analysis suggest that communication and strategic decision-making speed possess a significant positive impact on innovation performance. Also, strategic decision-making speed has sufficiently played the intermediary role between communication and innovation performance.Originality/valueThis survey specifies the effects of communication on the success of making fast strategic decision and innovation performance which aid Iranian food companies to tackle one of the managerial challenges: postponing strategic decisions due to lack of efficient communication to get information. In addition, to the best of the authors' knowledge, this essay is a first in Iran.

Purpose The purpose of this paper is to investigate the relationship between earnings management and chief executive officers’ (CEOs) compensation. Owing to the fact that earnings management does not have only opportunistic effects, but signaling effects, this study focuses on accruals quality to examine earnings management incentives. Thus, accruals quality is described against future cash flow. The empirical evidences suggest that a positive relationship between discretionary accruals and future cash flow provides predictive elements for earnings management, whereas a negative relationship between discretionary accruals and future cash implies to opportunistic elements for earnings management. Should there is no significant relationship between discretionary accruals and future cash flow, there will be no earnings management, and such a result suggests that incentives and managers’ performance in these firms differ. Design/methodology/approach The statistical population of this research consists of all listed companies on the Tehran Stock Exchange during 2009–2016. Panel data method is applied in order to estimate the research model. Findings Findings of the study show that there is no significant relationship between discretionary accruals and future cash flow in pharmaceutical and food industries, thus they have neither predictive nor opportunist earnings management, while the results evidence a negative significant relationship between discretionary accruals and future cash flow in machineries, automobile, mineral and chemical industries. Furthermore, it can be alleged that there is no significant difference between CEOs’ compensation in firms with opportunistic earnings management (OEM) and other types of earnings management. It shows that firms do not have appropriate plans for CEOs’ compensation. Moreover, the relationship between earnings management and stock return has been investigated in this study. We document that stock return is influenced by accruals quality and its components. In other words, stock return significantly differs in firms with OEM and firms without any kind of earnings management. Research limitations/implications The authors’ findings provide contributions; for managers, it is noticeable that stock markets have sufficient comprehension about financial statements and the undertaken procedures on them, resulting in a higher return base on fair information. For investors and regulators, using the findings, may have deeper understanding to distinguish between industries that are recognized as opportunistic and non-opportunistic, which, in turn, results in better decision and regulation. Originality/value Previous studies have been mostly investigated OEM, while the current study examines both signaling and opportunistic aspects of earnings management.
