Abstract The purpose of this thesis is to analyze if implied volatility and the implied risk neutral density function can predict short term market return of the Swedish OMX-index. To study the relation between information in option prices and short term market return I perform and OLS-regression with the market return as dependent variable. Implied volatility and the various moments of the implie
This paper analyzes production fragmentation in the telecommunications industry, using Hungary as a case study. The driving forces of production fragmentation are partly industry and product characteristics but also conditions in the environment, among which transaction cost are especially important. Because of its characteristics, the telecommunications industry has high fragmentation potential a
This paper conducts an empirical study of the determinants of credit default swap (CDS) prices. By using a new set of CDS quotes and explanatory variables for thirty major corporations, a set of linear panel data regressions are performed. The study confirms earlier research where risk free interest rate, volatility and leverage are found to be highly significant. In addition to this, a new variab
Foreign direct investment (FDI) is widely considered to be one of the main generators of so called spillover effects, where not only direct employment is a positive outcome but the whole economy can benefit in various ways. The recognition of spillovers has resulted in a more active role of host country governments to attract FDI. This thesis analyzes the FDI inflows in Slovenia and the role of pu
The main aim of this thesis is to investigate the implications and dynamics behind consistency between individual resource allocation decisions and corporate strategy concept. The telecom industry, a high-velocity environment going through an extensive deregulation process, is put under the magnifying glass. Japanese telecom giant NTT Group is compared to its German counterpart Deutsche Telekom. P
This thesis examines why working time preferences differ between workers and nations, and explains the effect of working time regulation and working time flexibility on negotiating work-life balance. In five separate sections the following working time issues are examined: the number of hours worked by workers in Europe; factors affecting individual working time preferences; how working time prefe
Convertible preferred shares are, the most frequently used investment instrument in venture capital or private equity investment. The various rights associated with these shares make them more valuable than ordinary shares. A vital feature, at least for the US venture capitalist, is the conversion right that is the right to convert a preferred share into an ordinary share. For the right of convers
The European Union today consists of 25 Member States. The Member States all have different tax systems and different rates of taxation. A few Council Directives have been adopted in order to harmonize direct taxation between the Member States, but none regarding cross-border losses. Losses are negative profits, they do not give rise to the levy of taxes but they may reduce the tax burden that wou
The solidarity clause was drafted a year after the terrorist attack in New York in 2001 and was informally further substantialised after the terrorist attack in Madrid in 2004. It became evident that terrorism is also a real and current threat to the Member States of the EU. The solidarity clause is now a part of the Constitutional Treaty (CT), which at the moment is subject to ratification in the
Climate engineering, or geoengineering, is large-scale technological intervention in the global climate system. How is this understood within our culture, what power relations are implied in the idea, and what are geoengineering's implications for sustainability? This thesis begins to examine this topic through the lens of culture by presenting a media analysis. It combines the quantitative me
The paper identifies the effects of the adoption of EU cohesion policy in Sweden, namely a significant involvement of subnational actors within designing and implementing the policy, a stimulated activity of regional authorities, a relationship between the different administrative levels mainly characterised by cooperation and dialogue and the increasing importance of flexible, inclusive, network-
Scientific abstract: As the increasing attentions drawn to the environment and climate change issue, the profound impact on the earth system made known to nearly every corner of the world. A great variety of global protocols and conventions has been established aiming to reduce global environmental risks and maintain a healthy earth system. In order to monitor, supervise these protocols and conven
We report quasiparticle calculations of the newly observed wurtzite polymorph of InAs and GaAs. The calculations are performed in the GW approximation (based on a model dielectric function) using plane waves and pseudopotentials. For comparison we also report the study of the zinc-blende phase within the same approximations. In the InAs compound the In 4d electrons play a very important role: whet
Objectives: With the introduction of sildenafil citrate (VIAGRA (TM)), the concept of phosphodiesterase (PDE) inhibition has gained tremendous interest in the field of urology. Cyclic nucleotide second messengers cGMP and cAMP have been assumed to be involved in the control of the normal function of the prostate. The aim of the present study was to evaluate by means of immunohistochemistry the exp
Macro- and microphase separation of compatibilizing graft copolymers in melt-mixed polystyrene/polyamide-6 blends was studied by transmission electron microscopy and thermal analysis. Three different graft copolymers with main chains of polystyrene and side chains of poly(ethylene oxide) were used as additives at various concentrations. The polyamide-6 domain sizes decreased with increasing amount
