A new model for analyzing differentiated fares and frequencies for urban bus services in...

The purpose of this paper is to develop a model for welfare evaluation of fare and frequency policies for bus services in smaller or medium-sized cities handling both congestion and crowding in public transport. The model with data for the city of...

Household Production and the Elasticity of Marginal Utility of Consumption

The popular approach to estimating the elasticity of marginal utility of consumption (EMUC) (Chetty 2006, "A New Method of Estimating Risk Aversion." American Economic Review 96 (5):1821-1834. doi:10.1257/aer.96.5.1821....

Modellering av slingor inom sjötransporter

The Swedish national freight transport model system Samgods is a freight model that simulates logistics decision at a disaggregated firm-to-firm level. The model calculates total annual transport demand in Sweden for all transport modes based on a...

Cost-Benefit Analysis of climate policy and long term public investments

This compilation dissertation consists of four essays with the common theme of welfare analysis of long-term public investments. The first two essays focus on analysis of climate change mitigation, i.e., the social cost of carbon dioxide. The third...

Does uncertainty make cost-benefit analyses pointless?

Cost-benefit analysis (CBA) is widely used in public decision making on infrastructure investments. However, the demand forecasts, cost estimates, benefit valuations and effect assessments that are conducted as part of CBAs are all subject to...

Household production and the Elasticity of Marginal Utility of Consumption

Chetty (2006) developed a new method of estimating the Elasticity of Marginal Utility of Consumption (EMUC) from observed work time responses to wage changes and derived an upper bound of 2 for this parameter. Here I show that the omission of...

Avoiding path dependence of distributional weights: Lessons from climate change economic...

 In some cost benefit analysis (CBA) applications, such as those used for the valuation of climate change damage, distributional weights are used to account for diminishing utility of marginal income. This is usually done by means of intra-temporal...

Temporal Aspects of the Social Cost of Greenhouse Gases

The purpose of this study is to investigate the temporal aspects of the social cost of greenhouse gases (GHGs). I am particularly interested in the interaction between time of emissions, discounting, and type of GHG (where different GHGs have...
