This study uses a rational ethical decision‐making framework to examine the influence of moral intensity (potential harm and social pressure) on whistleblowing intention and behaviour using organisational commitment as a moderator. A scenario was developed, and an online questionnaire was used to conduct an empirical analysis on the responses of 533 participants. The mean age and years of work experience of the respondents were 31 and 8.2 years, respectively. The results show, first, that while moral intensity is correlated with whistleblowing intention, only the potential harm is positively correlated with such intention. Second, potential harm and social pressure differentially affect whistleblower choice of using an internal or external channel. Third, organisational commitment has a moderated mediation effect among moral intensity, whistleblowing intention and behaviour. Fourth, whistleblowers may be grouped into four conceptual types: indifferent, rebel, mature and spoil. Finally, theoretical and managerial implications of the findings are discussed.  相似文献

This article presents a theory on the endogenous choice of education policy and the two‐way causal relationship between trade and education systems. A country's education system determines its talent distribution and comparative advantage; the possibility of trade by raising the returns to the sector of comparative advantage in turn induces countries to further differentiate their education systems and reinforces the initial pattern of comparative advantage. Specifically, the Nash equilibrium choice of education systems by two countries interacting strategically are necessarily more divergent than their autarky choices, and yet less than what is socially optimal for the world.  相似文献

This article presents methodology for identifying product categories that, if they were made the subjects of a specified state's export promotions, would hold promise for satisfying relevant needs of members of three key “stakeholder” groups regarding the outcomes of the governmentally sponsored export promotions: the World Trade Organization (WTO), managements of non-exporting, small- and- medium-sized (SME) manufacturing concerns, and governmental entities who are responsible for raising funds to support such promotions. Methodology is applied in the context of a state in the United States (North Carolina).

The methodology is then applied in the context of a state in the United States (North Carolina). The presentations of the results of the application of the methodology at each of the 2-, 4- and 6-digit HS-coded product category levels are in each case followed by discussions of implications of the results.  相似文献

Our study investigated the follower perceptions of leader–member exchange (FPLMX) as a mediator between leader political skill (LPS) and follower morale and tested these relationships using data obtained from casino dealers in Korea. Social astuteness, interpersonal influence, networking ability, and apparent sincerity are the indicators of LPS, while follower morale is composed of job satisfaction and affective organizational commitment. The results from structural equation modeling suggest that the research model we have proposed is viable. Broadly speaking, FPLMX is a partial mediator between LPS and follower morale.  相似文献

Textbook authors, in their presentations of aggregate demand–aggregate supply, are admonished to set their houses in order. The writers suggest the continued usefulness of the traditional “Keynesian cross” model as a pedagogical device and present a version that they allege to be superior to the popular AD–AS models found in many contemporary texts.  相似文献

This paper analyses the principal factors responsible for the growth in the value of imports of the UK food sector, during the period 1985-90. On the basis of estimates of translog multilateral price indices it assesses the relative contribution of changes in the quality of imported products and factors other than quality to growth in import values of food products. The main conclusion is that growth in quality appears to be the principal reason for the growth in unit values of imports and the trade deficit incurred by the food manufacturing sector.  相似文献
