This paper develops and examines the distinctions between the process of leadership, the person of the leader, and the job of leading. I argue that leadership is a delicate combination of the process, the techniques of leadership, the person, the specific talents and traits of a/the leader, and the general requirements of the job itself. The concept of leadership can and must be distinguishable and definable separately from our understanding of what and who leaders are, although the phenomenon of leadership can only be known and measured in the particular instantiation of a leader doing a job.  相似文献

Summary. The traditional model of sequential decision making, for instance, in extensive form games, is a tree. Most texts define a tree as a connected directed graph without loops and a distinguished node, called the root. But an abstract graph is not a domain for decision theory. Decision theory perceives of acts as functions from states to consequences. Sequential decisions, accordingly, get conceptualized by mappings from sets of states to sets of consequences. Thus, the question arises whether a natural definition of a tree can be given, where nodes are sets of states. We show that, indeed, trees can be defined as specific collections of sets. Without loss of generality the elements of these sets can be interpreted as representing plays. Therefore, the elements can serve as states and consequences at the same time.Received: 23 January 2003, Revised: 2 November 2003, JEL Classification Numbers: C72, D70.

The aim of this study is to research the adoption of International Financial Reporting Standards (IFRS) in Jordan, which was one of the first Middle Eastern emerging economies to adopt IFRS. The paper investigates the related factors that pressure and prevent such adoption over time, and illustrates the developmental aspects of such adoption. An interpretive methodology is employed, and perceptions of the study's participants are analysed regarding the adoption of IFRS in Jordan, which is an area that is under researched. Semi‐structured interviews were undertaken to collect Jordanian experts’ perceptions. Based on the empirical data analysis and prior theoretical and empirical literature, an adoption model was developed, which can serve future studies as well. The model illustrates the paradox of accounting changes in emerging economies, in which the actual conditions that pressure IFRS adoption are also the conditions that prevent full adoption. The model also provides an explanation of the implementation process of IFRS in emerging economies at both country and corporation levels. It combines practical features and related theories in an integrative model seeking to explain the phenomenon of IFRS as a new accounting regulation change.  相似文献

To increase the sparse knowledge about what drives organic food consumers in developing markets, Lebanese consumers' reasons and motives for buying organic food are studied in the framework of means‐end chain theory. A sample of N = 180 Lebanese consumers was interviewed in several retail outlets using a hard laddering questionnaire. The data were subjected to frequency analysis, cluster analysis, and structural equation modelling. Hierarchal value maps constructed from the laddering interviews revealed that “quality of life,” “pleasure,” and “peace of mind” are the main values driving organic food consumption in Lebanon. Frequent organic consumers displayed higher concern for their family's health and for the environment, whereas occasional organic consumers cared more about their own pleasure and were more likely to perceive organic food as a traditional and nostalgic product. Structural equation modelling revealed that “care for nature” and “care for children's health” significantly affect consumers' (self‐reported) purchasing behaviour. The found means‐end chains are a useful basis for marketing campaigns for organic food products in the Lebanese market. One focus of marketing campaigns should be raising consumers' awareness on the environmental benefits of organic production and the fact that it does not allow the use of harmful chemical products.  相似文献

Bangladesh, a labour-abundant country, is finally learning to reap gains from her labour abundance. The historical under-optimized capital–labour ratio of Bangladesh is slowly moving towards its optimum as the migration of its labour force and consequent inflow of remittance strategically converts its abundant labour into capital. Though the fear that remittance as an alternative source of earning may result in Dutch disease for existing family members; annual data for 1982–2013 and through applying standard testing methodologies, our empirical findings suggest that such a fear is not valid since remittance flow significantly improves domestic labour productivity in Bangladesh in the long run.  相似文献

We use regular vine (r-vine), canonical vine (c-vine) and drawable vine (d-vine) copulas to examine the dependence risk characteristics of three 20-stock portfolios from the retail, manufacturing and gold-mining equity sectors of the Australian market in periods before, during and after the 2008–2009 global financial crisis (GFC). Our results indicate that the retail portfolio is less risky than the manufacturing counterpart in the crisis period, while the gold-mining portfolio is less risky than both the retail and manufacturing sector portfolios. Both the retail and gold stocks display a higher propensity to yield positively skewed returns in the crisis periods, contrary to the manufacturing stocks. The r-vine is found to best capture the multivariate dependence structure of the stocks in the retail and gold-mining portfolios, while the d-vine does it for the manufacturing stock portfolio. These findings could be used to develop dependence risk- and investment risk-adjusted strategies for investment, rebalancing and hedging which more adequately account for the downside risk in various market conditions.  相似文献

We investigate the possible differences in the information content of stock dividends between firms that distribute stock dividends frequently (frequent distributors) and firms that distribute stock dividends infrequently (infrequent distributors) using a unique data set from Oman where the market microstructure frictions are either absent or limited. We find that infrequent stock dividend distributors have higher postdistribution operating performance relative to frequent distributors. We also find that the illiquidity measure is significantly related to the announcement effect only for frequent stock dividend distributors, whereas short‐term performance is significantly related to the announcement effect only for infrequent distributors. Our findings indicate that infrequent stock dividends are used mainly to convey favorable private information about the firms’ future prospects, and frequent stock dividends are used to reduce stock price to an optimal trading range in order to improve trading liquidity.

The research theorizes that environmental vulnerability can be minimized through mindfulness‐based strategies, and redesigning organizing processes, so that richer thinking is activated more quickly among greater number of people all of whom try to update their knowledge regardless of the knowledge source. It empirically evaluates the effects of organizational mindfulness and mindful organizing on resources and environmental sustainability. The model was tested in a very appropriate setting—Saudi Arabia, where increasing demand for and supply of energy culminates in unsustainable resources utilization and rise in greenhouse gas emissions and other environmental vulnerabilities. Data were collected from Saudi firms operating in the oil and gas sector and analyzed using SmartPLS software. The measurement and structural models were evaluated. The measurement model exhibits adequate model fit. The tests for the structural models show that four (of five) dimensions of organizational mindfulness (viz., commitment to resilience, deference to expertise, preoccupation with failure, and reluctance to simplify interpretations) and mindful organizing are significantly related at 5% significance level. Sensitivity to operations has no significant relationship with mindful organizing. Mindful organizing is significantly related to environmental and resources sustainability. Moreover, mindful organizing fully or partially mediates in the relationship between some of the dimensions of organizational mindfulness and environmental and resources sustainability. The study is one of the first to integrate mindfulness‐based approaches to sustainability and environmental research.  相似文献

For years, countries in the Middle East and North Africa (MENA) region have been trying to increase entrepreneurship rates and attract foreign investment, however, their bankruptcy statutes remained antiquated and punitive in nature. Potential start‐ups and foreign investors have been deterred from these markets due to a lack of alternative solutions to liquidation and a fear of punishment for business failure. At least seven countries in the region have now taken steps to modernize their bankruptcy laws to provide restructuring mechanisms and other measures designed to incentivize risk‐taking rather than to deter it. With this year's crash in oil prices, an unprecedented global pandemic and an imminent recession, an effective bankruptcy system has become even more critical to avoid catastrophic results for the employment rates and economic value of the companies in the region. However, despite these recent reforms, significant improvements are still needed to maximize the value and benefits of bankruptcy procedures in the face of these growing economic threats.  相似文献

This study examines the association between market risk disclosures (MRDs) and the investment efficiency of financial firms from six emerging markets in the Gulf Cooperation Council (GCC) region. Based on a sample of 553 firm‐year observations over the 2007–2011 period, we find that MRDs are significantly and negatively associated with both under‐investment and over‐investment and that this association is more pronounced for larger firms. We also find that the association between MRDs and under‐investment is moderated during periods of economic distress such as the Global Financial Crisis of 2008 and that the association between MRDs and over‐investment is magnified during periods of reduced financial distress. Our results are consistent with the idea that MRDs reduce information asymmetry, which ultimately improves investment efficiency. We contribute to the literature in an emerging market context by providing empirical evidence on the association between MRDs and investment efficiency across six emerging GCC capital markets. This study also fills a gap in the literature by providing evidence on the factors affecting the investment efficiency of financial firms.  相似文献
