The Bias of the Gini Coefficient due to Grouping
Ourti, Tom Van; Clarke, Philip - 2008
We propose a first order bias correction term for the Gini index to reduce the bias due to grouping. The first order … reveals an intuitive formula for the remaining second order bias which is useful in empirical analyses. We analyze the … it reduces a considerable share of the bias due to grouping. …

The Implementation of Marginal External Cost Pricing in Road Transport
Verhoef, Erik T. - 1998
This paper discusses a number of issues that will become increasingly important nowthat the concept of marginal external cost pricing becomes more likely to be implementedas a policy strategy in transport in reality. The first part of the paper deals with thelong-run efficiency of marginal...

Daily Exchange Rate Behaviour and Hedging of Currency Risk
Bos, Charles S.; Mahieu, Ronald J.; van Dijk, Herman K. - 1999
Exchange rates typically exhibit time-varying patterns in both means andvariances. The histograms of such series indicate heavy tails. In thispaper we construct models which enable a decision-maker to analyze theimplications of such time series patterns for currency risk management.Our approach...

Second-Best Congestion Pricing in General Static Transportation Networks with Elastic Demand
Verhoef, Erik T. - 1998
This paper studies the second-best problem where not all links of acongested transportation network can be tolled. The second-best taxrule for this problem is derived for general static networks, so thatthe solution presented is valid for any graph of the network, and forany set of tolling...

Traffic Congestion and Congestion Pricing
Lindsey, C. Robin; Verhoef, Erik T. - 2000
For several decades growth of traffic volumes has outstrippedinvestments inroad infrastructure. The result has been a relentless increase intrafficcongestion. This paper reviews the economic principles behindcongestionpricing in static and dynamic settings, which derive from thebenefits...

Aggregation Bias in Elasticities of Substitution and the Minimum Wage Paradox
Teulings, Coen N. - 1998

Second-Best Congestion Pricing in General Networks - Algorithms for Finding Second-Best Optimal Toll Levels and Toll Points
Verhoef, Erik T. - 2000
This paper considers the second-best problem where not all links of a congested transportation networkcan be tolled. The paper builds on earlier work, in which the second-best tax rule for this problem wasderived for general static networks, so that the solution presented is valid for any graph...

The Non-Parametric Identification of Lagged Duration Dependence
Frijters, Paul - 2000
In this paper, I consider the identification of lagged durationdependence in multiple spells without using the assumtion that there are additionalregressors orthogonal to the individual effects. The non-parametricidentification strategy is applied to the multiple non-employment spells of 2066...
