This article analyses the modified form of ad valorem royalty recently announced by the WA government in relation to gold production, which features a threshold price below which there is no tax liability and compares this royalty with a profit-based royalty. The level at which the threshold price is set plays an important role in determining the performance of the royalty in relation to its impact on production and the expected level and variability of tax revenue. It is argued that the higher this price is set, the stronger the grounds for preferring a profit-based royalty, even taking into account the reliability of each form for generating tax revenue. 相似文献

We construct an industry-equilibrium model in which it is costly for consumers who have previously purchased from one firm to switch to competitors. This gives firms a certain degree of market power over their established customers. The equilibria we identify under these conditions have the following properties: (1) there is a nontrivial size distribution of firms, although firms are intrinsically identical, (2) larger firms make higher profits, (3) larger firms spend more on R&D, (4) larger firms charge (on average) lower prices, and (5) profits are positively correlated over time. These properties match empirical regularities concerning the manufacturing and retail sectors in the U.S. economy. 相似文献

How to Become Central in an Informal Social Network: An Investigation of the Antecedents to Network Centrality in an Environmental SCM Initiative

Environmental supply chain management (SCM) initiatives often evolve as informal, grassroots efforts that are driven by policy entrepreneurs at lower management levels in an organization. These individuals usually are not in positions of power or authority to convince others to support the initiative. They thus rely on central positions in informal networks to gain access to and influence over other employees to be better able to sell these initiatives. This study examines how individuals arrive at positions of centrality within the networks surrounding environmental SCM initiatives. Linking social network theory and social capital theory with findings from the organizational behavior and environmental arena, the study investigates how an individual's proactive personality and commitment profile—affective, normative, and continuance commitment—might affect network centrality through the mediating role of championing behavior. Investigating the implementation of an environmental SCM initiative at a multinational enterprise, the authors identified a 90‐actor social network surrounding the initiative. The results provide evidence that championing behavior fully mediates the relationship between commitment and network centrality and to a lesser extent between proactive personality and network centrality. These findings suggest that championing behavior can enable an actor to become more central in social networks. Further, the results indicate that in an environmental SCM context, engendering the right type of commitment is a much more important driver of championing behavior than the proactive personalities of individual actors. This finding suggests that even employees who do not have proactive personalities can champion environmental initiatives and become central within the informal networks that surround these initiatives, if they strongly desire to support the initiative and believe that the initiative will lead to positive change. 相似文献

Many countries have adopted labeling policies for genetically modified (GM) food, and the regulations vary considerably across countries. We evaluate the importance of political‐economic factors implicit in the choice of GM food labeling regulations. Using an analytical model, we show that production and trade‐related interests play a prominent role in labeling decision‐making. This conclusion is validated by an empirical analysis of GM food labeling policy choices. We find that countries producing GM crops are more likely to have less stringent labeling policies. Food and feed exporters to the European Union (EU) and Japan are more likely to have adopted stricter labeling policies. Labeling regulations in Asia and Europe are similar to those of Japan and the EU. Countries with no labeling policies are less developed, with important rural sectors and are more likely to have ratified the Cartagena Protocol on Biosafety. 相似文献

We examine the mean and variance–covariance structure of log-wages over calendar time and the life cycle of British men, hereby controlling for birth cohort effects. We attribute the strong increase in mean log-wage during the 1980s and 1990s to a rise in mean log-wage with the year of birth. This rise is diminishing with the year of birth, which implies lower wage inequality between cohorts with the year of birth. Wage inequality has increased during the 1980s and early 1990s and remained fairly stable in the second half of the 1990s. The year effects, however, show increasing wage inequality up to 2001, mainly due to a strong rise in transitory wage inequality. Transitory wages are strongly correlated over time and an increase in transitory wage inequality therefore has highly persistent inequality consequences. The stable wage inequality in the second half of the 1990s is attributed to lower within-cohort wage inequality for the younger cohorts. The age effects show that permanent wage inequality increases with age, in particular up to age 30 and over age 50. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

ABSTRACT This paper seeks to respond to two particular aspects of Legge's work, her development of the concept of rhetoric and her commitment to the educative process. Legge has been drawing attention to the concept of rhetoric for a long time (e.g. Gowler and Legge, 1981 , 1996 [originally 1983]; Legge, 1989 , 1995a ). However, despite its popularity as an epithet, the process of rhetoric remains largely unexplored. Locating rhetoric within a poststructuralist view of language, this paper utilizes and explores the contribution of 'The New Rhetoric' to such an understanding, focusing on issues of style and context. This is used to illustrate a characterization of rhetoric which emphasizes its quality as a closed system with an important role in maintaining the status quo of 'managerialism'. Highlighting the key concept within 'The New Rhetoric' of audience , we suggest that to achieve change it is necessary to intervene in the closed cycle of the relationship between producers and consumers of management knowledge. 相似文献

The formation of social capital is hypothesised to enhance collective efforts for soil conservation. The Landcare Program in the southern Philippines promotes simple conservation practices in upland environments by supporting community landcare groups and municipal landcare associations, thus augmenting social capital. A study was conducted in 2002–2003 to evaluate the Landcare Program, using a mix of quantitative and qualitative techniques. In the present paper, the relationship between social capital formation and adoption of soil conservation in the Municipality of Lantapan is investigated. It is concluded that the Landcare Program as a whole created a valuable stock of bridging social capital, rapidly accelerating the adoption of contour farming measures, but that on‐going support is needed to maintain this capital stock. 相似文献

This paper analyses the issue of balancing the gains from trade with the risk of pest and disease transference. Two decision frameworks for determining whether or not to permit trade in a potentially invasive species-carrying good are presented. The first considers only the potential production losses resulting from an invasive species entering through a trade pathway, as is prescribed by WTO compliance. The second is a unilateral welfare-maximising approach which considers the consumer gains from trade, the loss of domestic producers’ market share and expected damage from the invasive species. It is shown that these alternative decision frameworks can be reconciled such that they produce the same outcome regarding whether or not trade is to be permitted. The key parameters which influence these decisions are also highlighted. 相似文献
