The report discusses options for reconciling the principle of Common but Differentiated Responsibility (CBDR) with IMO’s principle of equal treatment of ships when creating a markedbased measure for curbing CO2 emissions from international shipping. Global application with revenues used for...

Contract-relevant information asymmetries are known to cause inefficien-cies in markets. The information asymmetry is largest in the beginning of the customer-insurer relationship but reduces over time; the longer a poli-cyholder stays with the insurer the more the insurer learns about the...

Earlier theoretical models of unbalanced bidding in unit price contracts (UPC) ofter predict corner solutions, i.e. zero bids for unit prices of expected overextimated quantities. However, anecdotal evidence indicates a lack of zero bids in the actual contracts. We pursue a possible explanation...

The cost of short-sea shipping on the seas surrounding Sweden will increase considerably after 2015 as a result of the introduction of stringent emission limits on NOx and sulphur. This may give trucks and trains an upper hand in market segments where customers can choose between sea transport...

Cost overrun of transport projects is one of the most important problems in transport planning. It also makes the result of the cost-benefit analyses uncertain, thus decreasing their usefulness for decision making. In recent years more emphasis has been put on improving cost calculations and...

Risky driving behavior is regarded as being one of the best predictors of traffic accidents. Traffic violations certainly signal risky driving behvior, but the analysis of the linkage of traffic violations, individual and vehicle characteristics and annual mileage has so far been hampered by the...

The aim of this study is to estimate the price elasticity of demand for domestic air travel in Sweden. Using national aggregated data on passenger quantities and fares, price elasticities of demand are estimated with an unbalanced, in terms of stationarity, yet well performing model. The...

Usually transport systems, and roads in particular, are viewed as public goods. However, this is not always the case. In Sweden a large part of the road system is privately owned. Most of these privately owned roads are rural roads used by farmers and summer cottage owners, or used for forest...

A common approach for procuring large construction projects is through Unit Price Contracts. By the means of a simple model, we study the optimal quantity to procure under uncertainty regarding the actual required quantity given that the procurer strives to minomize expected total costs. The...

This paper studies the incentives for different countries to cooperate concerning pricing in transport systems, and how to handle the profit from such cooperation. Two types of simple networks with congestion are considered; one with parallel links, and one serial network with a number of...
