Assessing Budget Support with Statistical Impact Evaluation: a Methodological Proposal

Elbers, Chris; Gunning, Jan Willem; de Hoop, Kobus - 2007

Donor agencies and recipient governments want to assess the effectiveness of aid-supported sector policies. Unfortunately, existing methods for impact evaluation are designed for the evaluation of homogeneous interventions (‘projects’) where those with and without ‘treatment’ can be...

Train Commuters' Scheduling Preferences: Evidence from a Large-Scale Peak Avoidance Experiment

Peer, Stefanie; Knockaert, Jasper; Verhoef, Erik - 2015

collected during large-scale peak avoidance experiment conducted in the Netherlands, in which participants could earn monetary … rewards for traveling outside peak hours. The experiment included ca. 1000 participants and lasted for about 6 months. Holders … of an annual train pass were invited to join the experiment, and a customized smartphone app was used to measure the …

Evaluation of Development Policy: Treatment versus Program Effects

Elbers, Chris; Gunning, Jan Willem - 2009

There is a growing interest, notably in development economics, in extending project evaluation methods to the evaluation of multiple interventions (“programs”). In program evaluations one is interested in the aggregate impact of a program rather than the effect on individual beneficiaries....

Evaluation of Development Programs: Using Regressions to assess the Impact of Complex Interventions

Elbers, Chris; Gunning, Jan Willem - 2012

There is a growing interest in extending project evaluation methods to the evaluation of programs: complex interventions involving multiple activities. In general a program evaluation cannot be based on separate evaluations of its components since interactions between the activities are likely...

Transport Investment Appraisal and the Environment

Nijkamp, Peter; Ubbels, Barry; Verhoef, Erik - 2002

This review considers the role of environmental effects in transport investment appraisal, mainly from the perspective of cost-benefit analysis, the most widely adopted appraisal technique. Although the basic principles of CBA are straightforward, several complications are identified that may...

Time-Varying Tolls in a Dynamic Model of Road Traffic Congestion with Elastic Demand

Verhoef, Erik - 1997

In this paper, a dynamic model of road traffic congestion is presented, with an elastic overall demand for morning peak road usage, and with the congestion technology used being 'flow congestion'. It is demonstrated that in such a case, the optimal time-varying toll should include a 'flat',...

Congestion caused by Speed Differences

Verhoef, Erik; Rouwendal, Jan; Rietveld, Piet - 1997

In this paper, we investigate congestion caused by differences in desired or possible speeds. Especially outside peak hours, speed differences are probably one of the most important reasons for congestion. Although the model setting, with one lane and no overtaking, may seem simple at first...

Time, Speeds, Flows and Densities in Static Models of Road Traffic Congestion and Congestion Pricing

Verhoef, Erik - 1997

This paper studies some of the properties and fundamentals of static models of road traffic congestion that have triggered much debate in the literature. The first part of the paper focuses in particular on the difficulties arising with the backward-bending cost curve in the context of...
