Inflation uncertainty has been demonstrated both theoretically and empirically to lower real output. This paper examines the impact of inflation targeting in Canada on inflation uncertainty, as well as persistence. Our results indicate that inflation targeting lowered inflation persistence, but actually increased uncertainty. Such an effect may be due to the failure of the previous formal target, the M1 money supply, to successfully combat inflation.  相似文献

In search of maximizing efficiency, public organizations found solace in the adoption of employee performance management (EPM) systems. While research supports that managing employees’ performance has favourable outcomes, it is still unclear why and under which conditions. Moreover, EPM systems might even create additional pressures and therefore increase turnover intentions and undermine public organization’s quest to maximize efficiency. We argue that when EPM systems are carried out consistently (i.e. internal consistency) and when they link civil servants’ individual goals to the organization’s strategic goals (i.e. vertical alignment), civil servants will be less likely to leave the organization. Hierarchical linear regression analysis shows that internal consistency relates to increased satisfaction with the EPM system and affective commitment to the organization. Vertical alignment relates to lower levels of turnover intentions. This relationship was mediated by EPM system satisfaction and affective commitment. These findings that contribute to our understanding of EPM systems can lead to favourable outcomes.  相似文献

Adaptive co-management brings together collaborative and adaptive approaches in pursuit of sustainable resource use and social-ecological resilience. Enthusiasm for this management approach, however, is countered by recent critiques regarding outcomes. A lack of evidence from consistent evaluation of adaptive co-management further exacerbates this situation. This paper revisits the issue of evaluation in natural resource management and recasts it in light of complex adaptive systems thinking. An evaluative framework for adaptive co-management is developed which directs attention toward three broad components: ecosystem conditions, livelihood outcomes and process and institutional conditions. Scale-specific parameters are offered for each component to facilitate systematic learning from experience and encourage cross-site comparisons. Conclusions highlight the importance of systematically incorporating evaluation into the adaptive co-management process and recognize the challenge for resource agencies and researchers to shift from a conventional to a complex adaptive system perspective.  相似文献

Both the Information Theoretic Economics and Austrian Economics investigate the impact on market activity of problems of information and knowledge. The conceptions of information and knowledge they employ, however, as well as their respective views on and treatment of economic agency, are quite different. The purpose of this paper is to examine these differences, not primarily from an abstract philosophical point of view, but by looking at substantive examples of the economics offered by the two approaches. An attempt is made to explain the Austrian preference for non-formalist approaches to economic analysis.  相似文献

We develop an iterative and efficient information-theoretic estimator for forecasting interval-valued data, and use our estimator to forecast the SP500 returns up to five days ahead using moving windows. Our forecasts are based on 13 years of data. We show that our estimator is superior to its competitors under all of the common criteria that are used to evaluate forecasts of interval data. Our approach differs from other methods that are used to forecast interval data in two major ways. First, rather than applying the more traditional methods that use only certain moments of the intervals in the estimation process, our estimator uses the complete sample information. Second, our method simultaneously selects the model (or models) and infers the model’s parameters. It is an iterative approach that imposes minimal structure and statistical assumptions.  相似文献

To what extent have hospitals developed their skilled clinicians to perform the administrative and human resources (HR) manager role of the ward manager? We consider this research question through an analysis of an acute hospital called ‘The Hospital’ where the executive team is aiming to adopt a form of high-performance work system (HPWS). We focus primarily on explanations in terms of conditions, rather than the personalities of individual managers, which are most powerful in shaping their behaviour. There has long been a failure of hospitals (and other employing organisations) to develop fully the skills required by employees before they become line managers. Line managers are a critical link in the high-performance chain and this study illustrates that, despite their rhetoric, hospitals may still have much potential for implementing schemes to develop nurses further to prepare them for line-manager positions and to support them after they move into such roles. We infer from this study that such hospitals may not yet have completed the journey to having HPWS. Hence, there is still much scope for such hospitals to progress and enjoy the benefits that proponents claim for HPWS.  相似文献

When selling multiple products with asymmetric uncertainty, should the seller disclose product information so that customers do not have to incur any cost to resolve their uncertainties; if so, which product should the seller choose? To address these questions, we consider a monopolist selling two substitutable products to a group of consumers. Each consumer has asymmetric uncertainty regarding the two products. A total of four different information provision structures are considered based on whether the seller discloses information about each product with the aim of determining which strategy provides the seller with the greatest revenue. We derive several interesting results. First, the optimal information provision strategy depends on the magnitude of uncertainty in relation to the product with lower uncertainty. Specifically, if the uncertainty regarding the product with lower uncertainty is sufficiently small, it is optimal for the seller to provide information about the product with higher uncertainty, otherwise, the seller should provide information about both products. Second, when only one product's information should be revealed, it is optimal for the seller to choose the product with higher uncertainty and charge a higher price. Third, withholding information on both products is never optimal for the seller. Finally, our main model is extended by examining the Mean-Preserving Spread setting, and the robustness of our main results is confirmed. Furthermore, we examine the situation in which a monopolist sells a single product with two main attributes. We find that each of the four information provision strategies can be optimal under various scenarios.  相似文献
