This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).

New Zealand is currently the third largest global producer of kiwifruit and thus plays an important role in the international market. Exports of kiwifruit are also of significant horticultural value for New Zealand and in 2007 the kiwifruit industry accounted for export values of NZ$790 million. The global kiwifruit market has experienced substantial changes in recent years and is likely to change significantly in the near future due to developments in production sources, adjustments to trade policy settings and shifts in consumer preferences. The New Zealand kiwifruit industry needs to consider what the impacts of these changes might be so that future strategies can be constructed effectively. Little quantitative modelling has been done in New Zealand to consider the impacts of changes to the global kiwifruit industry. The major contribution of this research was the development and calibration of a kiwifruit industry-specific partial equilibrium trade model. The model was then used to examine the impacts on New Zealand producers of these trade-related changes in the global kiwifruit market.

The EU has had a special agreement with their former colonies in Africa, the Caribbean and the Pacific Islands, the ACP-countries, for almost 30 years. This has granted the ACPs with preferences on the Europen market, which have been excluded from other countries. The agreement is now beeing re-negotiated to make it more in terms with the rule of the WTO?s most favoured nation-principle. The new agreement will differ from the present one as it will be a mutual free trade agreement where the ACP countries will open their markets to the EU as much as the EU opens up it?s market to them.

At the department of Electronic Warfare Assessments at the Swedish Defence Research Agency in Linköping one of the activities is modelling and simulation of the duel between a robot and a target. The aim with this Master's thesis is to develop a simulation model of an hovering helicopter. First a theoretical description of the forces and moments acting on an helicopter is given. Then the equations of motion are derived. These equations are simplified to be valid only for a hovering helicopter and the result is a mathematical model.

In the light of ever increasing international trade around the globe, affecting men and women in all countries, it is surprising that so little attention is given its gender effects. The effects of trade are said to be gender neutral, but could potentially act reinforcing on the existing gender patterns in a society. The aim of this thesis is to examine whether the implications for men and women in relation to trade liberalization can be found to differ. By stylizing some differences between men and women, this is done by examining the theoretical implications mainly via the Heckscher-Ohlin model and through a Beckerian approach. The implications found are then compared with the findings in existing empirical work.

The aim of this thesis is to analyse the most common economic effects of countries pursuing trade facilitation. Trade flows are constrained by non-tariff barriers and through trade facilitation these barriers can be decreased. We will study the effects of trade facilitation from a theoretical perspective and evaluate a number of empirical studies. Several different trade barriers will be identified as well as those regions and countries that will gain the most from trade facilitation. We draw the conclusion thatlarge gains would prevail for all countries and that the consumers, businesses and the state all benefit from trade facilitation.

 This paper evaluates the effect of exchange rate risk on the sum of bilateral trade. To distinguish the effect between different types of countries, two groups are defined: advanced and developing economies. Economic theory on exchange rate risk and trade proposes ambiguous effects of increased volatility. However, the ex ante hypothesis is that developing economies are more sensitive to volatility. Contrarily to the hypothesis, the empirical results suggest that advanced economies would benefit up to twice as much from a removal of exchange rate risk.

International conventions signifies international trade, which in itself would be ineffective if there were no dispute settlement mechanisms. This essay intends to examine how dispute settlement mechanisms between states have developed over the years and a large emphasis is placed on the World Trade Organizations (WTO) Dispute Settlement Body since it?s had great significance for the efficiency of international law. In order to show the need for dispute settlement mechanisms, a background to the conventions that have called for the development of the DSB is in order. This essay focuses on Intellectual Property Rights (IPR), and the agreement that currently regulate intellectual property rights, Trade Related Aspects of Intellectual Property Rights (TRIPS), but also its connection to the DSB.

This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.

The relationship between free trade and the environment is often considered conflicting and the debates surrounding it are infected. My thesis deal with this conflict and how environmental concerns are integrated in three regional free trade agreements, North American Free Trade Agreement, The common market of the southern cone (MERCOSUR) and Southern African Development Community (SADC). I point out how the organizations differ from each other in this respect and I present a possible explanation to why they differ. The explanation is founded on the theory of the environmental Kuznets curve and that environmental concerns will depend on which level of development the member states in the organizations have. To judge and rank the organizations I have composed a model based on a pre-existing description of the trade and environment conflict.

In this study we examine trade patterns between Turkey and 13 member states of the European Union and how these have developed over the time period of 1983 ? 2006. To represent the industrial and agricultural goods included in the study we look at the United Nations Standard International Trade Classification (SITC). Following, we investigate internal differences in the EU by selecting four countries each to represent the Northern and Southern countries of the EU. Internal differences were studied in relation to the amount of trade occurring between Turkey and the Northern and Southern countries.

The purpose of this thesis is to get a better understanding of consumers? perception and knowledge of Fair Trade and Fair Trade products in Sweden. Literature was reviewed before the empirical research was conducted. A quantitative method, in form of a questionnaire survey, has been used. We have entered different areas related to our topic.

How does the recent wave of preferential trading arrangements affect, the incentives for further trade liberalization of member states, and the possibility of obtaining global free trade? And are there any differences in this aspect between custom unions and other forms of preferential trading arrangements? These questions are well debated and have divided international trade researchers into two camps, one in favour for preferential trading arrangements and the other side against them. I have used well acknowledged researchers in the area of international trade theory to make a literature study of the above mentioned key elements in the debate. When comparing the two sides I have focused mainly on their differences, assumptions and results. I have come to the conclusion that there is nothing to be alarmed by of the wave of regionalism that?s occurring in the world today, but caution should be applied and more research in this area is necessary before any certain conclusions can be drawn.

In May 2004 eight former communist countries (EU-8) with close historical trade ties to Russia joined the European Union. According to integration theory, we expect that Russia ? a so called third country ? in some cases may suffer from trade diversion due to this. This thesis focuses on the possible effects on Russian trade resulting from the 2004 eastern enlargement of the European Union. It aims to find out whether any evidence of trade diversion can be found.
