In this article, we look at a model with (independent) system operator who faces stochastic but growing transmission demand and a penalty if frequency is not balanced. In this set up, we derive an optimal grid expansion investment strategy and analyze its value and risk implications. It turns out that the firm value is strictly concave in the level of transmission demand. Firm value, however, increases with optimal investment for any level of demand. Moreover, firm risk is decreasing in the level of demand and higher when the firm has an investment option. The risk increase corresponds to the exercise of the call option and is stronger, the closer the firm approaches its exercise trigger.

The growing dissatisfaction with perceived distributional inequality and budgetary constraints gave rise to a discussion on the (re-)introduction of wealth taxes. Wealth taxes are typically levied on private wealth, in some countries also on corporate wealth. To avoid misleading statements concerning possible distributional consequences of wealth taxes, preceding analyses of the economic and particularly investment effects are necessary. As investments drive job creation, tax-induced changes in investment timing may significantly affect the income and wealth distribution. We analyze the impact of wealth taxes on investment timing under uncertainty and irreversibility and the propensity to carry out risky projects. Using a Dixit/Pindyck type real options model we find that wealth taxes have real effects. This means that higher wealth tax rates can either stimulate or depress the propensity to invest in risky projects. We find that apparently paradoxical wealth tax effects (accelerated investment due to higher wealth tax rates) are more likely for low interest rates and for high-risk investments. Using either historical cost or fair value accounting may affect investment timing ambiguously. Thus, the design of wealth taxes is crucial for the resulting delay or acceleration of investment. Although our model takes an individual perspective, our findings are also relevant for the current tax policy discussion on the introduction of wealth taxes. Our results indicate that wealth taxes are particularly harmful for specific classes of investments, for example low-risk investments.

In recent years, technological innovations have resulted in manifold applications using rare earth elements (REEs), leading to a dramatic increase in demand for them. Because of their unique physicochemical properties, REEs are considered indispensable in modern industry. They are extensively used in new materials, energy conservation, environmental protection and IT devices as well as in military weapon systems. They have also significantly contributed to the miniaturisation of electronic components, such as, for example, cell phones and laptop computers. REEs are essential for green technologies such as wind turbines. They are widely applied in the automotive industry for catalysts, hybrid vehicle batteries, motors and generators, etc. (Hurst, 2010). Due to the similarity of the chemical characteristics of each individual REE, the production processes for REEs with high purity are very complex: the processing and separation can be technically challenging. Furthermore, the chemical extraction processes involved have generated severe environmental problems. Currently, the supply of REEs is concentrated in China. To reduce the dependence on China, many countries have started to search for alternative REE sources, which can be classified into “primary sources” and “secondary sources”. Many REE exploration projects outside China and REE recycling projects have been launched. However, the success of the development of these projects is impacted by various risks, such as political risks, technical risks, environmental risks and social risks. The main research aim of this thesis is to establish a model for the evaluation of REE projects and to provide a basis for investment decision making. In order to complete this task, an analysis of REE deposits and the supply chain for REEs is provided. As results, a data base of potential REEs project is compiled, while an overview of the supply chain for REEs and an analysis of risks across the supply chain are presented. In order to assess potential REE production projects, a new real options valuation (ROV) model using a multi-dimensional binomial lattice approach is developed. For the application of the new real options model, a range of risk parameters and the expected production output of REE products are estimated using the Monte Carlo simulation method. The application of the new real options model is presented for the evaluation of the Bayan Obo mine in China, the Kvanefjeld REE project in Greenland, and a REE recycling project from magnetic scrap.

The objective of the International Financial Reporting Standards (IFRS) is to provide useful information to the users of financial statements to assist in making economic decisions. To be useful, information has to be relevant and reliable, but the reliability of information suffers when the guidelines for the reporting of specific issues are not clear and managerial discretion arises. Write-offs are one of those accounting issues that are regularly related to earnings management. By now it is seen as common knowledge that write-offs, especially those on goodwill, do not reflect declines in asset value; rather, they are used as a device to manipulate financial reports. However, there is a striking lack of grounded theoretical research that can confirm this assessment. The aim of this dissertation is to provide valuable analytical and empirical insights on fixed asset write-offs under IFRS. In a first step, the practical implementation of IAS 36 in Europe has to be analyzed, which is best done empirically. Based on the findings from these empirical surveys, the most substantial questions remaining are subject to an in-depth analytical discussion. Since IAS 36 entails different measurement issues that have their origins in finance theory, this dissertation also aims to introduce some basic techniques from theoretical finance to accounting research. Lastly, as the analyses presented in this dissertation do not cover all open questions on fixed asset write-offs, the author hopes to encourage further research on this important topic.
