This dissertation studies issues related to the evaluation of the effects and interactions of transport and environmental incentive policy instruments. Essay 1: Green cars sterilize congestion charges: a model analysis of the reduced impact of Stockholm road tolls calibrates a modal-choice model with data from the Stockholm road toll and uses it to study the sensitivity of congestion toll effects to some seemly subtle changes in the toll system design and external circumstances. Essay 2: The impact of consistent internalization of external effects of transport and manufacturing – a CGE analysis of Sweden uses a static, small open-economy Computable General Equilibrium (CGE) model of the Swedish economy to study the impact of the consistent internalization of external effects of transport and manufacturing. We examine and compare the effects and tradeoffs of different policy reforms on domestic emissions reduction, carbon leakage, macroeconomic variables, social welfare, government budget, and transport demand. Essay 3: Estimating the value of transport time savings for freight transport: a simultaneous decision model of the choices of transport mode and shipment size applies a simultaneous decision model of the choices of transport mode and shipment size to study the value of transport time savings (VTTS) of Swedish shippers for four commodity groups: agricultural goods, forest goods, mining goods, and manufactured goods. Essay 4: Estimating the additionality of the Swedish climate subsidy program – Klimp studies an important issue related to the climate subsidy program – additionality. We estimate the probability that a subsidized project would have been implemented in the absence of the subsidy to assess the additionalityof the Klimp program
