The Saskatchewan Wheat Pool went from being the largest grain handler in western Canada in the mid 1990s to undertaking a $405 million debt restructuring in January 2003. Provincial grain handling market share had been over 60 percent for two decades prior to the Pool becoming publicly traded in 1996. With the share conversion, the Pool began a capital expenditure program in an effort to adapt to industry deregulation and to compete with the multinationals that were entering western Canada. This program was not successful. SWPs long-term debt increased five fold over the period 19961999 and consecutive multi-million dollar net losses were incurred followed by the debt restructuring.<p>This thesis uses dominant logic theory and the principal-agent problem to analyze what went wrong at SWP. Theory suggests organizations faced with major industry change may have difficulty revising their dominant logic, which leads to organizational failure. Not only is there a tendency to hold on to established beliefs, but the creation of new beliefs is prone to error because of bounded rationality. The existence of a principal-agent problem can worsen an organizations ability to revise its dominant logic. Information asymmetry and the principals trust of the agent can lead to inaccurate beliefs and ineffective strategies being approved. <p>The results of personal interviews with twenty-one past management and elected Saskatchewan Wheat Pool personnel and grain industry affiliates are presented and analyzed in a case study format. The results suggest that deregulation of the grain handling industry and the anticipated arrival of multinational competitors pressured the Pool to respond quickly to major industry change. The Pool had difficulty revising its dominant logic; it retained outdated beliefs and accepted inaccurate new beliefs. Interviewees described how some investments were built on erroneous beliefs and lacked complete due diligence. Evidence suggests the principal-agent problem was also at play. The need for confidentiality after the share conversion increased information asymmetry, and management took advantage of the boards lack of experience as investments extended beyond the farm gate. The principal-agent problem in conjunction with an inaccurate revised dominant logic is a reasonable explanation for the Pools failure.

The case study was made in the area of Kiru Valley, Tanzania, in order to study the conflicts over the water in the river Dodumera, and also to understand how the villages Mawemairo, Matufa and Mapea have been affected by the construction of the IFAD irrigation scheme. The aim was to connect the conflicts in the area with a general view of how water can create such conflicts. The method used in the case study was semi-structured interviews. The results from the interviews made with farmers and officials in Kiru Valley was analysed through general theories about water conflicts and theories about governing common-pool resources, such as Ostrom’s eight principles and the theory the Tragedy of the Commons. The analysis was also made through the IFAD poverty reduction strategy programme (PRSP). The conclusion made on the basis of this analysis was that the IFAD project, in Kiru Valley, was in correlation with the PRSP and an attempt to reduce poverty in the two villages Mawemairo and Matufa. The project has been very successful and has contributed to an increase of livelihood and development in the villages. However, the scheme has also affected other villages, such as Mapea. The scheme has contributed to a decrease of water availability in the Dodumera River for Mapea. Nowadays they only rely on rain-fed irrigation. The conflicts have been affected by the scheme, not so much in the quantity of the conflicts but more in the target of the conflicts. Before the construction of the scheme the conflicts was directed at the big-scale farmers, now they are directed at the scheme. On the other hand, the scheme has helped reducing the conflicts between the farmers in Mawemairo and Matufa. There are solutions to conflicts and water scarcity, such as more efficient irrigation techniques and Ostrom’s principles on governing the common-pool resources.

The chapters of this dissertation examine efficiency failures in three areas of applied microeconomics: experimental economics, public finance, and game theory. In each case, we look at ways to resolve these failures to promote the public good. The first chapter, “An Experimental Test of the Pigovian Hypothesis,” looks at two different policies designed to reduce congestion in a common-pool resource (CPR). We present an experiment with training and a simplified decision task and find that subject behavior converges to the Nash prediction over a number of periods. A Pigovian subsidy effectively moves subject behavior to the pre-subsidy social optimum. Finally, we find a significant but non-persistent effect of information provision in moving subjects toward the social optimum. The second chapter, “Apples to Apples to Oranges,” looks at efficiency and equity failures across states resulting from public expenditure. This chapter introduces an extension of the Representative Expenditure System that uses regression methods and both state and metropolitan statistical area (MSA) level data, allowing for comparability of input costs, service requirements, and levels of need. The regression-based results are robust across state- and MSA-level formulations, although state-level approaches overestimate need for larger, less populous states. All regression-based results diverge from previous workload-based approaches. The third chapter, “Evading Nash Traps in Two-Player Simultaneous Games,” looks at efficiency failures in two-player simultaneous games. This chapter presents two new concepts: “détente” and “no-initiative,” in which players consider their own strategies and other-best-responses. We discuss their efficiency and descriptive properties across a set of simultaneous games.

Addressing climate change is a major undertaking. Agricultural soil has the potential to assist in decreasing the concentration of GHGs in the atmosphere by storing CO2 in the soil. Carbon offset markets have been suggested as a cost effective means of reducing GHG emissions. Farmers can increase their soil sink potential by applying Beneficial Management Practices (BMPs) that enhance carbon sequestration through improvements to soil, nutrient and livestock management practices (Fulton et. al., 2005). Whether or not a market for carbon offsets will emerge depends on a number of factors which mainly are related to the profitability of the BMPs and the costs of implementing a carbon contract. Provided that a market for carbon offsets emerges, the effectiveness of the market depends, in part, on the degree to which buyers and sellers in the market comply with the terms of the contracts they sign. The resource costs associated with monitoring and verification may result in incomplete monitoring. As long as monitoring is not perfect, non-compliance will be an issue. <p>The analysis that will be performed in this thesis introduces non-compliance in the economic analysis of carbon-offset market. The purpose of this work is to examine the overall cost effectiveness of the carbon-offset market when introducing non-compliance. <p>Firstly the theoretical model investigates the incentives for different farmers to participate in the carbon offsets market as well as incentives for engaging in cheating. The model recognizes farmers heterogeneity with respect to cost differences and examines the economic determinants of farmers non-compliance as well as the consequences of non-compliance on the performance of the carbon-offset market. Results support the standard finding that the extent of producers non-compliance decreases with an increase in the audit probability and/or an increase in the penalty per unit of non-compliance. In addition, the number of producers participating in the carbon offsets market is shown to increase with an increase in the carbon-offset price.<p> The analysis then introduces intermediaries in the market that will take care of trading carbon offsets as well as monitoring producers. The traders role in this study is played by an IOF (investor owned-firm) or a PA (producers association). Within the IOF, the analysis focuses on the monopoly and oligopoly structures. The key role of the traders is to guarantee, based on the amount of monitoring that is undertaken, that the emitters purchase only carbon offsets that actually correspond to sequestered carbon. The analysis then examines three cases for the group that monitors farmers compliance a group owned by for-profit traders, a government-run agency and a group owned by the PA trader. This part of the thesis examines what impact the involvement of the traders in the carbon-offset market has on non-compliance, as well as how the structure of the monitoring group affects non-compliance and the amount of carbon offsets traded in the market. The results of the analysis show that the monitoring groups always undertake sufficient monitoring to ensure that full compliance is achieved thus, while non-compliance is possible, it does not occur in equilibrium. The finding suggests that the formation of a government monitoring agency can potentially increase traded output and lower the price paid by emitters, still these changes are likely to be small, particularly when the trading sector is monopolistic. The overall analysis in this chapter shows that the optimal amount of enforcement, and as a result the cost effectiveness of a carbon-offset market, depends on the nature of the organization that undertakes the enforcement. <p>The next consideration of the thesis is the heterogeneity attributed to the timing of sequestration by different farmers. The analysis focuses on the carbon offsets pooling by considering two structures for the aggregator: a for-profit aggregator and a producers association. Pooling resources enables the farmers to benefit from economies of scale. The pricing schedule used by the aggregator is a two-part tariff. The two-part tariff is used as a way of providing an incentive for the farmers sequestering large amounts of carbon to participate in the pool. The study considers two alternatives for the coefficients that might be used to decide on the amount of carbon offsets to which each farmer will be entitled: default coefficient and custom coefficients. Each situation is modeled in a principal agent framework. <p>The analysis examines how the aggregator will target the monitoring service for different group of farmers. The investigation reveals that, under different scenarios, a PA or a FPA (for-profit aggregator) might lead to the formation of a heterogeneous pool or a homogeneous pool of each type. <p>The last issue investigated in this dissertation is the coexistence of a FPA and a PA in the default coefficient case. The analysis show that both aggregator structures can exist together in the market in the same time if the savings in the monitoring costs made possible by the PA are smaller than the cost of organizing the pool. If this condition is not satisfied the FPA cannot survive in the market and the producers association will dominate. <p>In addition to providing a better understanding of how the carbon-offset market may perform when introducing non-compliance, the results of this study can assist in assessing the cost effectiveness of the carbon-offset market when enforcement is undertaken by different organizations. Furthermore, the last consideration of the pooling option might help in selecting which type of pool a heterogeneous or a homogeneous one might perform better under different alternatives.

Refrigeration systems employing the NH3-H2O absorption cycle provide cooling using a thermal energy input. This cycle relies on the zeotropic nature of the refrigerant - absorbent pair: because of the difference in boiling temperatures between NH3 and H2O, they can be separated through selective boiling in the desorber. Desorbers with counter-current flow of the solution and generated vapor enable efficient heat and mass transfer between the two phases, reducing the absorbent content in the generated vapor. Flow visualization experiments at temperatures, concentrations and pressures representative of operating conditions are necessary to understand the heat and mass transfer processes and flow regime characteristics within the component. In this study, a Flooded Column desorber, which accomplishes desorption of the refrigerant vapor through a combination of falling-film and pool boiling, was fabricated and tested. Refrigerant-rich solution enters the top of the component and fills a column, which is heated by an adjacent heated microchannel array. The vapor generated within the component is removed from the top of the component, while the dilute solution drains from the bottom. Flow visualization experiments showed that the Flooded Column desorber operated most stably in a partially flooded condition, with a pool-boiling region below a falling-film region. It was found that the liquid column level was dependent on operating conditions, and that the pool-boiling region exhibits aggressive mixing between the vapor and solution phases. Heat transfer coefficients were calculated from the data for the pool-boiling region, and were compared with the predictions of several mixture pool-boiling correlations from the literature. The correlations from the literature were in general unable to predict the data from this study adequately. It was found that the Flooded Column desorber yielded higher heat transfer coefficients within the pool-boiling region than those predicted by these correlations. Therefore, modifications to existing mixture boiling correlations are suggested based on the findings of this study. The resulting modified correlation predicts 33 of the 35 data points from this study within ±40%, with an average absolute error of 19%.

The sun is a huge energy source with great potential of providing energy to the heating of homes and other buildings in an environmentally sustainable manner. In order to provide buildings with energy from the sun it is necessary to transfer the energy supply over time to when the demand arises. By storing the heat in a seasonal storage, solar energy from the summer can be used in the winter when the demand for heating is greatest. Today's existing plants are mainly in Europe and particularly in Germany. These facilities are designed to supply heat demands greater than 400 MWh and covers about 40-50 % of this need which consists of energy for space heating and domestic hot water. How much of the heat demand that is covered, the solar fraction, is partly due to losses from the storage which in turn is connected to the surface area of the storage. The bigger a storage, the smaller the losses because of the decreasing relationship between surface area and storage volume. Looking at the size of the seasonal storages that are currently in operation, the question if seasonal storage is also suitable for installations designed for heat demands smaller than 400 MWh arises. Jonas Haglund at the architect office Skanark AB in Karlstad is planning an accommodation of 40 flats and hopes that seasonal stored solar energy can serve as the main energy source for space heating and hot water. In order to make housing more attractive he is considering the idea of adding other features, like a pool and an atrium, that also require heating but with lower temperature requirements. Haglund would like to investigate whether the efficiency of the solar collector increases when the extra energy demands are added and if the energy cost, for those demands, in this way can be reduced. The purpose of this study is to investigate the possibility of covering a large fraction of a small-scale annual heat demand corresponding to about 40 newly built apartments. The study shall present the solar fractions that can be achieved with different storage concepts when storage size and collector area is varied. The study will also answer how the solar fraction will change if a heating demand with lower temperature requirements and varied character is added to the basic domestic heating and if the added energy demand to some extent can be free. These questions are answered by calculations and simulations with the simulation software COMSOL Multiphysics. The results show that it is possible to obtain solar fractions above 80% with sufficient collector area. Suitable storage volume varies depending on the specific storage concept. Simulations of seasonal storage in a tank show that a storage volume of 13 m3/MWh is an appropriate size, while the corresponding figure for duct storage in clay is 20 m3/MWh. An added heating demand of low temperature character increases the efficiency of the solar panels and creates, so called, free energy. / Examensarbete

This thesis is about the work of Nordel, an advisory body set up in 1963 by the largest power companies in Denmark, Finland, Norway and Sweden. The purpose of Nordel was to strengthen and consolidate Nordic cooperation in the production and transmission of electrical power. The analysis has been conducted by using Elinor Ostrom’s framework for studying common-pool resources, which is described in her book Governing the Commons: The Evolution of Institutions for Collective Action (1990). The thesis concludes that Nordel reaffirmed the bilateral practises already established by the individual power companies and was circumscribed by national energy policies. Nordel’s main contribution to the Nordic cooperation was to act as a forum for common technical issues and general aims, and as a knowledge-producing organisation.
