Effects of Foreign Direct Investment inflows on growth in Central and Eastern European transition countries

The aim of this master’s thesis is to analyze the effects of Foreign Direct Investments on growth in selected Central and Eastern European transition countries. The theoretical part of this thesis, introduces growth theories and how FDI is covered in those theories. In addition, the results from previous studies, which have studied FDI’s effect on growth, are presented in this master’s thesis. This work introduces also the economical progress during the transition period in selected countries. In the empirical part’s regression model, it will be searched for the direct effect of FDI on growth with panel data collected from nine transition countries.

Venture capital investment on SME

This thesis studies venture capital investment on small and medium-sized enterprises (SMEs). The specific objective of the study is to test whether venture capitalists have a positive effect on SMEs. In addition effect of several other factors is studied in financial crisis. Used determinants are formulated based on three capital structure theories. The pecking order theory concerns favoring on financing source over another. The agency theory and the tradeoff theory concentrate on the search of optimal capital structure. The data of this study consist of financial statement data and results of corporate questionnaire. Regression analysis was used to find out the effects of several determinants. Regression models were formed based on the presented theories. SMEs with and without venture capitalists were considered separately. It was found that venture capitalists have a positive effect on SMEs. Although some results between SMEs with and without venture capitalists were mixed.

Investment risks in Russia: A Finnish perspective

Purpose of this study is to analyze the effect of Russia's economic environment changes in the total return indexes of Finnish companies. The research data consisted of Finnish publicly listed companies, which have made physical investments to Russia, and operating in the area. The study used six different variables to model the Russian operating environment. The data consists of total return indexes of Finnish companies. From those we calculated the monthly mean interval between timeline of 1 January 2000 to 31 December 2009. Sample period is divided into two different parts. Variables impact on companies' total return indices is tested by regression analysis. By F-test we tested significance of model and squared coefficient correlation told us how much model explains from changes. Goodness of the β-coefficient is tested in the model by t-test. The research results shows that the Russian operating environment, or changes in which the active Finnish companies in total return indices. On partial sample periods results were not so significant.

Management of interdependency in project portfolio

Project management has evolved in recent decades. Project portfolio management, together with multi project management, is an emerging area in the project management field in practice, and correspondingly in academic research and forums. In multi project management, projects cannot be handled isolated from each other, as they often have interdependencies that have to be taken into account. If the interdependencies between projects are evaluated during the selection process, the success rate of the project portfolio is increased. Interdependencies can be human resources, technological, and/or market based. Despite of the fact that interdependency as a phenomenon has roots in the 1960s and is related to famous management theories, it has not been much studied, although in practice most companies use it to great extent. There exists some research on interdependency, but prior publications have not emphasized the phenomenon per se, because a practical orientation practitioner techniques prevails in the literature. This research applies the method triangulation, electronic surveys and multiple case study. The research concentrates on small to large companies in Estonia and Finland, mainly in construction, engineering, ICT, and machinery industries. The literature review reveals that interdependencies are deeply involved in R&D and innovation. Survey analysis shows that companies are aware of interdependency issues in general, but they i have lack of detailed knowledge to use it thoroughly. Empirical evidence also indicates that interdependency techniques influence the success rate and other efficiency aspects to different extents. There are a lot of similarities in interdependency related managerial issues in companies of varying sizes and countries in Northern Europe. Differences found in the study are for instance the fact that smaller companies face more difficulties in implementing and evaluating interdependency procedures. Country differences between Estonia and Finland stem from working solutions to manage interdependencies on a daily basis.historical and cultural reasons, such as the special features of a transition country compared to a mature country. An overview of the dominant problems, best practices, and commonly used techniques associated with interdependency is provided in the study. Empirical findings show that many interdependency techniques are not used in practice. A multiple case study was performed in the study to find out how interdependencies are managed in real life on a daily basis. The results show that interdependencies are mostly managed in an informal manner. A description of managing the interdependencies and implementation procedures is given. Interdependency procedures are hard to implement, especially in smaller companies. Companies have difficulties in implementing interdependency procedures and evaluating them. The study contains detailed results on how companies have implemented working solutions to manage interdependencies on a daily basis

Varallisuudenhoito indeksiosuusrahastoilla

Tässä tutkielmassa käsiteltiin varallisuuden hoitoa indeksiosuusrahastoilla (excange-traded fund). Tavoitteena oli selvittää yleisesti indeksiosuusrahastojen ominaisuuksia sekä rakentaa excelissä indeksiosuusrahastoista sijoitussalkku. Kuukausituottoainestona oli iSharesin 31 indeksiosuusrahastoa vuosilta 2006 - 2009. Havaintoja oli yhteensä 1468. Tutkimuksessa havaittiin, että aikavälillä 2006 - 20009 indeksiosuusrahastot seuraavat hyvin vertailuindeksiään, sisältävät keskimäärin markkinoihin nähden vähäisesti riskiä sekä tarjoavat tasaista tuottoa.

Arvo- ja momentum-strategioiden yhdistäminen Suomen osakemarkkinoilla

Tämän tutkielman tavoitteena on selvittää pystytäänkö momentum-strategiaa hyödyntämällä parantamaan arvostrategian tuottoja Suomen osakemarkkinoilla. Yhdistetyn arvo- ja momentum-strategian lisäksi tutkitaan myös arvosrategian menestystä. Tutkimuksessa arvostusmittareina on käytetty P/E-, P/B-, P/CF-, P/S-, P/D-, EV/EBITDA-lukuja sekä kolmea näistä muodostettua yhdistelmätunnuslukua. Tutkimusaineisto koostuu Suomen osakemarkkinoilla julkisesti noteerattujen osakkeiden tuottoaikasarjoista vuosilta 1992-2008. Osakkeet on järjestetty tunnuslukujen ja momentum-indikaattorien perusteella kolmeen tertiiliportfolioon. Sijoitusten pitoaikana on käytetty yhtä ja kolmea vuotta. Portfolioista on raportoitu keskimääräisen vuosituoton lisäksi riskikorjattu tuotto Sharpen luvulla ja Jensenin alfalla mitattuna sekä näiden tilastollinen merkitsevyys. Tulosten perusteella voidaan päätellä, ettei momentum-strategian avulla pystytä parantamaan arvostrategian tuottoja Suomen osakemarkkinoilla. Arvostrategia menestyi kuitenkin erittäin hyvin etenkin yhdistelmätunnuslukujen sekä P/D-, EV/EBITDA- ja P/E-lukujen osalta.

Investment recovery period in electric motor of higher efficiency in pumping for irrigation

In this study, it was adjusted a mathematical model to measure the effect of electric motor efficiency on pumping system costs for irrigation on the tariff structure of conventional electricity and green horo-seasonal , and also to calculate the recovery period of the invested capital in higher efficiency equipment. Then, it was applied to a center pivot irrigation system in two options of electric motor efficiency, 92,6% (standard line) and 94,3% (high efficiency line), and the acquisition cost of the first corresponded to 70% the of the second. The power of the electric motor was 100hp. The results showed that the model allowed us to evaluate if a high efficiency motor was economically viable compared to the standard motor in each tariff structure. The high efficiency motor was not viable in the two tariff structures. In the green horo-seasonal tariff, would only be viable if its efficiency was 4.46% higher than the standard motor. In the conventional tariff, it would only be viable if the efficiency overcame 2.71%.

Risk Parity: A Modern Tool for Diversification

The purpose of this study is to examine how well risk parity works in terms of risk, return and diversification relative to more traditional minimum variance, 1/N and 60/40 portfolios. Risk parity portfolios were constituted of five risk sources; three common asset classes and two alternative beta investment strategies. The three common asset classes were equities, bonds and commodities, and the alternative beta investment strategies were carry trade and trend following. Risk parity portfolios were constructed using five different risk measures of which four were tail risk measures. The risk measures were standard deviation, Value-at-Risk, Expected Shortfall, modified Value-at-Risk and modified Expected Shortfall. We studied also how sensitive risk parity is to the choice of risk measure. The hypothesis is that risk parity portfolios provide better return with the same amount of risk and are better diversified than the benchmark portfolios. We used two data sets, monthly and weekly data. The monthly data was from the years 1989-2011 and the weekly data was from the years 2000-2011. Empirical studies showed that risk parity portfolios provide better diversification since the diversification is made at the risk level. Risk based portfolios provided superior return compared to the asset based portfolios. Using tail risk measures in risk parity portfolios do not necessarily provide better hedge from tail events than standard deviation.

Varallisuudenhoito indeksiosuusrahastoilla

Tämä Pro gradu–työ on käytännönläheinen sijoittajalähtöinen tutkimus varallisuudenhoidosta indeksiosuusrahastoilla. Tavoitteena on selvittää indeksiosuusrahastojen olemusta, niiden hyötyjä sekä mahdollisia haittapuolia. Toisena tavoitteena on rakentaa indeksiosuusrahastoista aikaisemman tutkimuksen pohjalta mallisalkku. Kolmantena tavoitteena on luoda Excelin portfolio-optimoinnilla salkku, jossa tutkitaan indeksiosuusrahastojen suoriutumista markkinoilla. Tämä optimointimetodi on rakennettu Mika Vaihekosken (2002) mukaan. Tutkimusmenetelmänä on empiirinen tutkimus. Tarkastelen aihetta pääosin liiketaloustieteellisestä näkökulmasta. Tutkimuksessa käytetään myös paljon rahoitusmarkkinalähtöistä näkökulmaa. Tutkimusaineisto koostuu kolmestakymmenestäneljästä Yhdysvaltain markkinoiden osake-, joukkovelkakirja- sekä raaka-aineindeksiosuusrahastosta. Aineisto on vuosilta 2006 – 2011 sisältäen 34x69 havaintoa. Portfolio-optimoinnissa käytetään neljää hyperbola-kerrointa. Empiiristen tutkimustulosten mukaan indeksiosuusrahastojen menneisyyden hyvät tuotot ennustaisivat hyvin tulevaisuuden hyviä tuottoja ainakin tämän tutkimuksen aikavälillä tammikuusta 2006 syyskuuhun 2011. Valinta-aikavälin 2006 – 2008 aineistosta muodostettu tangenttiportfolio menestyi suhteellisen hyvin hallussapitoaikavälillä 2009 – 2011. Tangenttiportfolio osoittautui ainakin tässä tutkielmassa käyttökelpoiseksi työkaluksi indeksiosuusrahastojen varallisuudenhallinnassa.

Monte Carlo Hypothesis Testing with The Sharpe Ratio

The purpose of this master thesis was to perform simulations that involve use of random number while testing hypotheses especially on two samples populations being compared weather by their means, variances or Sharpe ratios. Specifically, we simulated some well known distributions by Matlab and check out the accuracy of an hypothesis testing. Furthermore, we went deeper and check what could happen once the bootstrapping method as described by Effrons is applied on the simulated data. In addition to that, one well known RobustSharpe hypothesis testing stated in the paper of Ledoit and Wolf was applied to measure the statistical significance performance between two investment founds basing on testing weather there is a statistically significant difference between their Sharpe Ratios or not. We collected many literatures about our topic and perform by Matlab many simulated random numbers as possible to put out our purpose; As results we come out with a good understanding that testing are not always accurate; for instance while testing weather two normal distributed random vectors come from the same normal distribution. The Jacque-Berra test for normality showed that for the normal random vector r1 and r2, only 94,7% and 95,7% respectively are coming from normal distribution in contrast 5,3% and 4,3% failed to shown the truth already known; but when we introduce the bootstrapping methods by Effrons while estimating pvalues where the hypothesis decision is based, the accuracy of the test was 100% successful. From the above results the reports showed that bootstrapping methods while testing or estimating some statistics should always considered because at most cases the outcome are accurate and errors are minimized in the computation. Also the RobustSharpe test which is known to use one of the bootstrapping methods, studentised one, were applied first on different simulated data including distribution of many kind and different shape secondly, on real data, Hedge and Mutual funds. The test performed quite well to agree with the existence of statistical significance difference between their Sharpe ratios as described in the paper of Ledoit andWolf.

Dynamic Ownership in Family Business System – A Portfolio Business Approach

Family businesses are among the longest-lived most prevalent institutions in the world and they are an important source of economic development and growth. Ownership is a key to the business life of the firm and also one main key in family business definition. There is only a little portfolio entrepreneurship or portfolio business research within family business context. The absence of empirical evidence on the long-term relationship between family ownership and portfolio development presents an important gap in the family business literature. This study deals with the family business ownership changes and the development of portfolios in the family business and it is positioned in to the conversation of family business, growth, ownership, management and strategy. This study contributes and expands the existing body of theory on family business and ownership. From the theoretical point of view this study combines insights from the fields of portfolio entrepreneurship, ownership, and family business and integrate them. This crossfertilization produces interesting empirical and theoretical findings that can constitute a basis for solid contributions to the understanding of ownership dynamics and portfolio entrepreneurship in family firms. The research strategy chosen for this study represents longitudinal, qualitative, hermeneutic, and deductive approaches.The empirical part of study is using a case study approach with embedded design, that is, multiple levels of analysis within a single study. The study consists of two cases and it begins with a pilot case which will form a preunderstanding on the phenomenon. Pilot case develops the methodology approach to build in the main case and the main case will deepen the understanding of the phenomenon. This study develops and tests a research method of family business portfolio development focusing on investigating how ownership changes are influencing to the family business structures over time. This study reveals the linkages between dimensions of ownership and how they give rise to portfolio business development within the context of the family business. The empirical results of the study suggest that family business ownership is dynamic and owners are using ownership as a tool for creating business portfolios.

Observations of Industry Momentum Effect in European Equity Indices

This thesis examines the existence and nature of momentum effect in European equity indices. A set of predefined indicators is used to compose momentum portfolios and different holding periods are used to test the strategies over variable time periods as well as under different economical conditions. The data consists of daily closing prices of STOXX Europe 600 index and its 18 super sector indices. Over the study period we follow the performances of a long position in the Winner portfolio, a position in the market neutral zero-cost portfolio and also a position in the risk-controlled zero-cost portfolio. The investment ratio of the risk-controlled zero-cost portfolio is negatively correlated with the realized market volatility. The results show that momentum effect is present in European industries and is most prominent in the short-term. Indicators that are based on short-term performance tend predict the over- and underperformers for the 1-month holding period more reliably than any other indicator/holding period combination. The examination of the strategies under different economical conditions shows that the market neutral approach can create significant returns in times of recession but in times of economic boom the long position in Winner portfolio outperforms the market neutral portfolio by an extensive margin.

Innovation Project Portfolio Management

Companies today are forced to innovate in order to remain within business. Such innovation projects undertaken by the companies are defined in this study as creative ideas which have been managed through “Stage-Gate” innovation process. This process is used to manage innovation projects as they proceed from being newly created to ready for launching/implementing. This has ensured that the companies manage the innovation project right. However, with so many new creative ideas the companies can come up within limited resources, the companies must rely on Innovation Project Portfolio Management (IPPM) to ensure that they are managing only the right innovation projects. Although, there are many tools and techniques available for use within Project Portfolio Management, there is still no consensus on which are the most effective and no standard framework has been established especially for IPPM. Thus, this study proposes a practical framework for which individual innovative organization can follow as a guideline to manage its innovation project portfolio. The study theoretically first addresses the key differences between project portfolio management of innovation projects and other traditional projects - one of which is the stage nature of innovation projects due to their unclear objectives from the beginning compare to clearly established objectives of traditional projects. Secondly, different tools and techniques which can be used are examined based on the three goals of IPPM: (1) Maximizing the Value of Innovation Project Portfolio: Financial Methods, Decision Trees, Scoring Models and Checklists; (2) Balancing Innovation Project Portfolio: Visual Representations; and (3) Aligning Innovation Project Portfolio with Strategy: Bottom-Up (Scoring Models with Strategic Criteria) and Top-Down (Strategic Buckets). Finally, the two approaches in which IPPM can be integrated with Stage-Gate innovation process are discussed: (1) Gates- Dominated; and (2) Portfolio Reviews-Dominated. Practically, this study investigates IPPM of a case organization, and through analysis of the case study results proposes a practical framework for case organization to improve its current management of innovation project portfolio. This framework is then generalized to propose a final practical framework or guideline for which an innovative organization can follow to manage its innovation project portfolio.
