Lars Olsson disputerade 2007 på avhandlingen: Effects of certainty on decision making under uncertainty : using subsidies to reduce production of environmental harmful products
The Kyoto Agreement resulted in the global goal of reducing carbon dioxide emissions. In order to meet this goal, among other things governments need to implement and evaluate strategies to reduce the increasing trends in production and consumption. The aim of this Ph.D. project is to investigate whether and how governments can subsidize for instance oil producers in a free market so that they reduce their production.
The main focus of this project is price settings in a free market where producers compete with each other. Without influencing this competition, it would be possible for governments to subsidize the oil producers for what they do not sell (produce), thus creating incentives for them to not reduce prices below a certain level. It is however an empirical question to be addressed in the project how decision makers will react to different levels of governmental subsidies as well as uncertainties about this level over time, and uncertainties about how competitors will act. Also, any possible effects on competition will be investigated.
Experimental methods for studying simulated markets developed in psychology and experimental economics will be used.
The results show that the investigated subsidy system lead to the expected effects of reduced sales (and thereby production) by increased price setting. Uncertainty of the size of the subsidy did not change the results. Also, and importantly, the competitive behaviour of the decision makers were not influenced by the subsidy, still it inhibited the start of price wars as was the case without the subsidy.
The proposed subsidy system may be used as a complement to the European Emission Trading Scheme in markets not covered by the scheme (i.e. fuels for private cars), reducing emissions levels toward the goals of the Kyoto Protocol. It may also be used as a tool to reduce the overuse of scarce resources (i.e. cod).
