The Cost Effectiveness of Environmental Policy Instruments in the Presence of Imperfect Compliance
No full textWe aim to integrate information, monitoring and enforcement costs into the choice of environmental policy instruments. We use a static partial equilibrium framework to study different combinations of regulatory instruments (taxes, standards…) and enforcement instruments (criminal fine, administrative fine…). The firms’ compliance decisions depend on the instrument combination selected by the government. The model is used to compare the welfare effects of different instrument combinations for the textile industry in Flanders. We find that administrative, implementation, enforcement and monitoring costs are important to decide on the necessity of an environmental policy. Moreover, we show that emission taxes are not necessarily the most cost-effective instrument. This result holds even if we include industry heterogeneity. The decision of whether to pursue an environmental policy or not depends crucially on the formulation of an appropriate monitoring and enforcement policy.K32 Environmental Law, K42 Illegal behaviour and enforcement of law, Q28 Government policy

No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The Relative Efficiency of Market-based Environmental Policy Instruments with Imperfect Compliance
No full textThis paper examines to what extent incomplete compliance of environmental regulation mitigates the distortions caused by pre-existing labour taxes. We study the relative cost efficiency of three market-based instruments: emission taxes, tradable permits and output taxes. In a first-best setting and given that monitoring and enforcement is costless, we find that the same utility levels can be reached with and without incomplete compliance. However, allowing for violations makes the policy instruments less effective. The nominal tax rate needs to be higher or the number of permits issued smaller, in order to obtain the required emission reduction. Including monitoring and enforcement aspects, and more specifically fines, into the model in a second-best setting, provides us with a new means of collecting tax revenues and of lessening existing tax distortions. We show that the relative position of grandfathered tradable permits vis-à-vis emission taxes improves considerably when allowing for incomplete compliance in a second-best settingEnvironmental policy, instrument choice, monitoring and enforcement
Trip chaining: who wins who loses?
No full textIn this paper we study how trip chaining affects the pricing and equilibrium number of firms. We use a monopolistic competition model where firms offer differentiated products as well as differentiated jobs to households who are all located at some distance from the firms. Trip chaining means that shopping and commuting can be combined in one trip. The symmetric equilibriums with and without the option of trip chaining are compared. We show analytically that introducing the trip chaining option can, in the short run, only decrease the profit margin of the firms and will increase welfare. The welfare gains are however smaller than the transport cost savings. In the long run, with free entry, the number of firms decreases but welfare with trip chaining possible is still higher than when it is excluded. A numerical illustration gives orders of magnitude of the different effects.trip chaining, discrete choice model, general equilibrium model, imperfect competition, wage competition.
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
