This paper examines the small-sample performance of spatial HAC (SHAC) estimators of the standard errors on parameters. We find that, in small to moderately-sized datasets, the use of HAC estimators may be recommended only with a relatively large degree of cross-sectional interdependence.  相似文献

An important assumption in economic studies of climate policy is the social welfare function. This paper shows that applying distinct decision or social welfare criteria can result in different optimal policies of climate control, notably if climate change impacts are uncertain. First, decision criteria in current climate-economic studies are reviewed. Next, the most important alternatives are discussed, including their (mathematical) formalization and incorporation in economy-climate models. Most of these alternative criteria suggest more stringent climate policies to be optimal than the standard discounted utilitarianism approach. However, several important welfare criteria have not or hardly seen any application in the economic analysis of climate policy. We conclude that there is clear need for systematic research on this theme, for which the current review provides a solid basis.  相似文献

This paper tests the Ricardian equivalence hypothesis in the context of the Dominican Republic (DR). The results rejected the Ricardian theorem but a weaker version is shown to have significant implications for the DR. If the government borrows to increase spending, private consumption is crowded out and the economy will suffer in the long run. The outcome is worst if the government borrows to deliver a tax cut. In particular, for every RD$ 1.00 of additional debt incurred to finance government primary spending, private consumption and gross domestic product (GDP) fall by a meaningful RD$ 2.15 and RD$ 1.15 respectively. If the debt is used to finance the tax cut, the fall is RD$ 2.15 in both consumption and output. Interestingly, if the government uses taxes to cover a budget deficit, the effect is neutral and consistent with Ricardian equivalence. The paper argues that fiscal distortions are in part responsible for these multipliers. Distortions are estimated to be 21 % coming from different sources including taxes evasion and fiscal drainage. These findings suggest that the DR could benefit from either reducing the level of fiscal distortions or the size and scope of the Dominican government. If, however, the government continues to pursue an active fiscal role under the current environment, it will generate an unnecessary burden to consumption and economic growth.  相似文献

Studies in the behavioral ethics and moral psychology traditions have begun to reveal the important roles of self-related processes that underlie moral behavior. Unfortunately, this research has resulted in two distinct and opposing streams of findings that are usually referred to as moral consistency and moral compensation. Moral consistency research shows that a salient self-concept as a moral person promotes moral behavior. Conversely, moral compensation research reveals that a salient self-concept as an immoral person promotes moral behavior. This study’s aim was to integrate these two literatures. We argued that compensation forms a reactive, “damage control” response in social situations, whereas consistency derives from a more proactive approach to reputation building and maintenance. Two experiments supported this prediction in showing that cognitive depletion (i.e., resulting in a reactive approach) results in moral compensation whereas consistency results when cognitive resources are available (i.e., resulting in a proactive approach). Experiment 2 revealed that these processes originate from reputational (rather than moral) considerations by showing that they emerge only under conditions of accountability. It can thus be concluded that reputational concerns are important for both moral compensation and moral consistency processes, and that which of these two prevails depends on the perspective that people take: a reactive or a proactive approach.  相似文献

Advertising remains one of the most popular marketing instruments, and many studies have studied its sales effectiveness. However, prior research has either looked at the total spending of a brand/firm, or has focused on the most popular media, especially TV advertising. Even though huge amounts are also spent on “smaller” media such as billboards and cinema, little is known on their effectiveness.  相似文献

Whilst much research has been conducted on decision support for electronic negotiations and some research has been done on communication support in this area, there is a lack of research on the interplay between these two elements of negotiations. The questions whether both are equally important, whether one effects the other, or whether they show counter-effects are important both for negotiation training (i.e. what should be the focus for becoming a good negotiator) and for system research (i.e. which system support elements need to be developed). The current paper presents results of a controlled laboratory experiment with negotiators that were provided with decision support and communication support and negotiators that had only communication support available. The impact of decision support on the communication process and on outcome dimensions as well as the impact of communication behaviour on the negotiation process and the qualitative dimensions of the outcome will be discussed.  相似文献

Financial service providers are facing a major paradigm shift. The understanding of what eventually constitutes customer value is being extended; economic value as the sole core of exchange is a far too limited perspective in contemporary competition. To address this emerging shift, the purpose of this study is to reframe the logic of value creation in financial services. As a result, a tentative framework for value creation logic in financial services is developed and discussed. On the basis of the framework, financial service providers should not limit their attention and resources to the exchange process, but identify innovative value-creating mechanisms through which they could contribute to the customer value actualization process. Our tentative framework (i) offers financial service providers guidance on which innovative value-creating mechanisms would enable them to participate in their customers’ value actualization process; (ii) shows how a product becomes a channel for a service, specifically a solution possessing value in the customer’s routine processes; (iii) illustrates that researchers and service providers should develop their understanding of customers beyond the traditional loan, insurance and/or investment product orientation.  相似文献

Survey evidence shows CFOs to believe that earnings management can enhance investor valuation of their firms. This evidence raises the question of correspondence between the beliefs of CFOs and investors. Surveying financial analysts to gain insight into how earnings management influences investor perception of firm value, we find analysts’ and CFOs’ beliefs to be generally consistent. We find that analysts perceive meeting earnings benchmarks and smoothing earnings to enhance investor perception of firm value and all earnings management actions to reach a benchmark, save share repurchases, to be value destroying. CFOs, however, are reluctant to repurchase shares, preferring to use techniques viewed by analysts as value destroying (e.g., reductions in discretionary spending). Analysts’ inability to unravel such techniques perhaps explains CFOs’ preferences.  相似文献

There are several (mathematical) reasons why Dupire’s formula fails in the non-diffusion setting. And yet, in practice, ad-hoc preconditioning of the option data works reasonably well. In this note, we attempt to explain why. In particular, we propose a regularization procedure of the option data so that Dupire’s local vol diffusion process recreates the correct option prices, even in manifest presence of jumps.  相似文献

This paper analyses the implementation of the ‘dual system’ in Dutch municipalities which was part of a package of New Public Management‐reforms. This system was stimulated by Dutch central government and called for more accountability for performance of municipal managers and the board of mayor and aldermen, as well as for the use of more output and outcome information. Interviews of participants on four different hierarchical levels in 12 municipalities show that the practices of output management at different hierarchical levels are only loosely coupled to each other (‘vertical loose coupling’). We also found some degree of ‘horizontal loose coupling’ at each hierarchical level between result orientation, the development of output indicators and the use of output information for performance evaluation. The paper analyses the reasons why municipalities encounter difficulties in designing a comprehensive and coherent performance management system.  相似文献
