This article investigates the role of taxation when public goods are privately provided. Externalities between consumers via the public good are shown to cause kinks in social indifference curves. As a result, a government restricted to income taxation should engineer enough inequality to ensure there are some non-contributors to the public good. Whether commodity taxation changes this conclusion depends on the extent to which consumers "see through" the government budget constraint. If they can, inequality should still be sought. When they cannot, in contrast to the case of an economy with only private goods, commodity taxation can be used in conjunction with income transfers to achieve the first-best. 相似文献
The paper addresses the question of what constitutes an appropriate evaluation strategy for national foresight activities in different situations. The variety of rationales for foresight is explored, ranging from a desire to set priorities through to participation-oriented goals and building new networks around common visions and strategies. A generational model of foresight is used to show the evolution of key evaluation issues. The generic motivations for evaluation of accountability, justification and learning are discussed in the context of foresight. Evaluation grounded in the concept of behavioural additionality and the systems failure rationale is shown to be more suited as a rationale for foresight as public policy.Assessing the effects of foresight requires an understanding that it is only one of several influences on public policy. To be effective it needs to be tuned into the strategic behaviour and cycles of policy and economic actors. Cases are presented of evaluation of foresight programmes in the United Kingdom, Germany and Hungary. It is concluded that there is no “one-size-fits-all” evaluation approach and that the method selected is conditioned by motivation, timing and the level of aggregation. Foresight cannot be fully evaluated independently from its context. Foresight is being strengthened by the emergence of rigorous and systematic knowledge to assist learning and improvement. 相似文献
Problems of intergovernmental policy coordination can take many forms and are becoming increasingly important with continuing economic integration. In this paper we focus on the fiscal competition problem where the non-cooperative choice of taxes and transfers among governments typically leads to a suboptimal outcome. We look at the effect of two widely used corrective policies: revenue sharing and expenditure sharing (or intergovernmental matching grants). Our main result is that these two corrective policies have opposite effects depending on the form of competition between governments, namely whether governments compete in taxes or expenditures. More precisely, for any form of competition, revenue sharing is desirable exactly when expenditure sharing is not and vice versa. The implication is that the choice of the optimal corrective policy requires a complete understanding of the underlying non-cooperative behavior among governments. Our second main result is that neither revenue sharing or expenditure sharing can be sustained as a Nash equilibrium among governments, although all governments would benefit from one of these two corrective policies. Central intervention is therefore inevitable unless governments can pre-commit to the optimal corrective policy before setting their fiscal policies. 相似文献
This paper provides new evidence on the impact of electronic trading on brokerage commissions by investigating a sample period that covers the period of transition from floor to electronic trading on the Sydney Futures Exchange. After controlling for liquidity, volatility and broker identity, the introduction of electronic trading remains to be associated with lower brokerage commissions relative to floor markets. The study also provides new evidence on brokerage commissions in futures markets finding that commission fees charged on futures trades average 0.002% of transaction value. This is up to 120 times smaller than the magnitude of brokerage fees charged in stock markets, and considerably lower than the magnitude of brokerage fees assumed for futures markets in previous research. Consistent with existing studies based on stock markets, commissions charged per contract decrease with order size reflecting economies of scale in the provision of brokerage services in futures markets. Commission rates are positively related to bid-ask spreads and price volatility, which proxy for the probability of execution error costs and execution difficulty, respectively. Finally, the identity of the broker is found to be a significant determinant of commissions reflecting different pricing schedules across brokers. 相似文献
This article provides new evidence on the effect of changes in employment protection on worker absence. We use novel multi‐organization data to examine changes in worker absence as workers move from temporary to permanent employment contracts. We demonstrate a robust positive effect of employment protection on sickness absence. It has also been suggested that the impact of employment protection on absence and effort is due to a fear of dismissal. We also provide evidence that suggests that temporary workers' absence is influenced by incentives to attain jobs with protection that is unrelated to threat of dismissal. This has not been considered in earlier research. This channel of employment protection effects has important policy implications. 相似文献
In this diary study, we examined a theoretical model in which the psychological conditions of meaningfulness, availability, and safety serve as mechanisms through which the work context during discrete situations within the workday influences “state” engagement. We further theorised that a person's “trait” level of engagement would exert cross‐level effects on the state level relationships. Multilevel analyses based on a sample of 124 individuals in six organisations and 1,446 situational observations revealed that meaningfulness and availability (but not safety) mediated the relationships between perceptions of the work context and state engagement. High levels of trait engagement strengthened the within‐person relation between availability and state engagement, yet weakened the within‐person relation between meaningfulness and state engagement, suggesting two different processes may be at play. Overall, the findings advance our understanding of engagement as a multilevel and temporally dynamic psychological phenomenon and promote a contextually based HRM approach to facilitating engagement. 相似文献
Objective:Venous thromboembolism (VTE) (deep vein thrombosis [DVT] and pulmonary embolism [(PE]) represents a substantial economic burden to the healthcare system. Using data from the randomized EINSTEIN DVT and PE trials, this North American sub-group analysis investigated the potential of rivaroxaban to reduce the length of initial hospitalization in patients with acute symptomatic DVT or PE.Methods:A post-hoc analysis of hospitalization and length-of-stay (LOS) data was conducted in the North American sub-set of patients from the randomized, open-label EINSTEIN trial program. Patients received either rivaroxaban (15?mg twice daily for 3 weeks followed by 20?mg once daily; n?=?405) or dose-adjusted subcutaneous enoxaparin overlapping with (guideline-recommended ‘bridging’ therapy) and followed by a vitamin K antagonist (VKA) (international normalized ratio?=?2.0–3.0; n?=?401). The open-label study design allowed for the comparison of LOS between treatment arms under conditions reflecting normal clinical practice. LOS was evaluated using investigator records of dates of admission and discharge. Analyses were carried out in the intention-to-treat population using parametric tests. Costs were applied to the LOS based on weighted mean cost per day for DVT and PE diagnoses obtained from the Healthcare Cost and Utilization Project dataset.Results:Of 382 patients hospitalized, 321 (84%), had acute symptomatic PE; few DVT patients required hospitalization. Similar rates of VTE patients were hospitalized in the rivaroxaban and enoxaparin/VKA treatment groups, 189/405 (47%) and 193/401 (48%), respectively. In hospitalized VTE patients, rivaroxaban treatment produced a 1.6-day mean reduction in LOS (median?=?1 day) compared with enoxaparin/VKA (mean?=?4.5 vs 6.1; median?=?3 vs 4), translating to total costs that were $3419 lower in rivaroxaban-treated patients.Conclusion:In hospitalized North American patients with VTE, treatment with rivaroxaban produced a statistically significant reduction in LOS. When treating DVT and PE patients, clinicians should consider newer anti-coagulants with less complex treatment regimens. 相似文献
This paper critically examines the methods of transportation used by independent tourists and how importantly they value mobility throughout their journeys. While independent tourists are frequently identified as being adventurous and highly mobile, relatively few researchers have critically examined the modes of transport they use or the importance they play in enhancing and fulfilling their desired experiences. Indeed, most literature portrays independent tourists as habitual users of public transport as opposed to modes of personal transport. In this paper, the notion of automobility – a combination of autonomous and self-directed movement – is explored from the perspective of independent tourists in Norway. A multi-method qualitative study was undertaken which analysed the views of 38 independent tourists at eight different locations. The findings revealed that personal modes of transport were intrinsic features of the journeys undertaken and that they offered alternative sensory experiences in contrast to public transport. Moreover, for many independent tourists, autonomous journeys were considerably more important than the destinations they visited. Thus, for many independent tourists in Norway, demands for control, flexibility and adventure could only be satisfied by using particular modes of transport. 相似文献
