Full textO presente trabalho pretende estudar a persistência das empresas de alto crescimento e as suas características, através da recolha de todas as empresas portuguesas presentes na base de dados Amadeus, durante um período de dez anos, dividimos o conceito de empresas de elevado crescimento em empresas de elevado crescimento de volume de negócios e empresas de elevado crescimento de empregados, para responder à pergunta se as empresas assim classificadas num determinado período do tempo, seriam capazes de manter taxas de crescimento elevado para vários períodos e se as suas características permaneceriam estáveis ao longo do tempo. O período de análise foi dividido em sete subperíodos. Notou-se que, a maioria das empresas que foram classificadas como de empresas de alto crescimento no primeiro período não foram capazes de manter este estatuto no período seguinte.
The purpose of this work is to analyze the growth persistence of high-growth firms and their profile characteristics, by collecting data of all the Portuguese firms present on Amadeus database for a ten-year period (i.e. from 2006 to 2015), We divided the high-growth concept in two versions ("employment high-growth firms" and "turnover high-growth firms") to answer the question if firms that were qualified as high-growth firm in a certain period of time, would be able to maintain the high growth rates for multiple periods and whether their profile characteristics would remain stable over time. The analysis period was divided into seven sub-periods. It was noted that most companies that were classified as of high growth firms in the first period were not able to maintain this level in the following period.

Full textMålet med denna studie är att undersöka relationen mellan riskkapital och snabbväxande företag. Tidigare studier har undersökt relationen på företagsnivå där riskkapitalets positiva effekt på innovation, firmatillväxt och ekonomisk tillväxt har påvisats. Dock har forskningsfältet saknat ett tillvägagångssätt på en mer aggregerad nivå. Med en fixed effects-modell applicerad på paneldata med en beroende variabel bestående av antalet snabbväxande företag och en oberoende variabel bestående av mängden riskkapital, undersöks relationen på landnivå med ett urval av 20 länder. Studien visar inga signifikanta resultat bortsätt från kontrollvariabeln BNP per capita som är positiv och signifikant. Slutsatsen i arbetet är att den data som finns tillgänglig idag inte är mogen för studier på en aggregerad landnivå då brus i form av andra faktorer som påverkar snabbväxande företag i ett land fångas upp. Företagstillväxt mätt i tillväxt i antalet anställda i ett företag kan även vara en föråldrad metod. Dagens moderna företag präglade av affärsmodeller som inte kväver arbetskraft för att skala upp verksamheten på samma sätt som företag traditionellt gjort historiskt.

Full textI en alltmer komplex och instabil global miljö ökar hoten om störningar i försörjningskedjan. Dessutom har högväxtföretag, som är bland de viktigaste bidragande faktorerna till den globala ekonomin, ingen specifik vägledning vad gäller denna fråga, medan akademiker upplever en kunskapslucka med avseende på dessa typer av företag. Forskare har tidigare betonat vikten av motståndskraft i försörjningskedjan för att företagen ska kunna motstå störningar och katastrofer, men har hittills bara antagit perspektiven hos industrier eller etablerade företag. Syftet med denna avhandling var således att utforska rollen som organisatoriska egenskaper i ett företag med hög tillväxt spelar och hur dessa påverkar leveranskedjans motståndskraft och dess konceptuella komponenter. Empiriska resultat föreslår att ett företag med hög tillväxt kan uppnå tillräcklig motståndskraft utan etablerad riskhantering. Därför kan egenskaperna hos ett företag med hög tillväxt i sig öka motståndskraften. Vidare föreslås att de konceptuella komponenterna som avgör leveranskedjans motståndskraft inte har lika betydelse under hela organisationens livscykel. Därför måste organisationer med hög tillväxt tillämpa motståndsmål och åtgärder som är i linje med företagets övergripande tillväxtplan, samtidigt som de tar hänsyn till den dynamiska karaktären av deras egen tillväxt.

Full textHigh-growth firms account for a disproportionate share of new job creation in most economies. This has led to the emergence of a diverse agenda that examines these firms to determine their characteristics and the engine behind their superior growth rate. In particular, there is abundant literature that focuses on developed countries with a large portion of the research tilted towards prescribing growth enabling public policy changes. In the context of developing countries, little or no attention was given to high-growth firms. Hence, it is the purpose of this research to investigate high-growth firms in the Ethiopian market setting which has registered unprecedented economic growth rate for the past 10 years.In doing so the different chapters of this research are devoted to transforming the definition of a high-growth firm by giving the necessary attention to the growth engendering phenomenon from an entrepreneurial dimension, centering the role of the entrepreneur and entrepreneurship as the catalyst of growth. As such, the research formulates a HGEF definition aided by a theoretical framework that exhibits the growth strategy and process of firms with the aim of emphasizing the role of the entrepreneur and entrepreneurship in inducing a superior growth rate.The research takes a particular focus on to what extent business environment obstacles may hamper HGEFs in Ethiopia by studying the impacts of infrastructure, public utilities, capacity, administrative burden and procedures, finance, and corruption to HGEFs operation together with a search for their incidence level.To test the contribution of Ethiopia’s HGEF to new job creation, both quantitative and qualitative methods are applied under “Convergent Parallel Mixed Methods Design” research format. The first phase of the investigation will utilize the World Bank data of 848 Ethiopian firms to measure incidence level and business environment impact analysis. In the second phase, the result of the field work that captured data through interviews of 9 HGEFs to verify and test preliminary findings will be used to add new insight to the issue.The findings of the research convey counterintuitive outcomes that shows that HGEF potential for development through new job creation resides in traditional sectors of the economy with minimal presence in sectors that necessitates high capital and technical investment.Moreover, the level of adaptability and compatibility of HGEFs with corruption level in the business environment provides a result that contradicts the commonly held academic position that argue the intrusive nature of corruption and its impact on firm growth rate.Finally, in conjunction with the developmental centric academic perspective the research concludes by emphasizing the need to incorporate the idiosyncratic representation of entrepreneur and entrepreneurship in public policy design to favor growth and to tailor support according to the life cycle of firms

Full textBackground: High-growth firms contribute to a majority of all newly created jobs in Sweden. Recent studies have shown that these companies encounter problems and growth barriers as a result of their rapid growth. After investigating the study field of high-growth firms we found an absence of research that seeks to explain why they are not persistent over time. We consider it to be of interest to study the phenomenon of internal growth barriers. Aim: The aim of this study is to identify internal growth barriers in high-growth firms through the perspective of the founders. In relation to this we examine how the high-growth firms undertake and overcomes these barriers. Completion: This study is based on a qualitative research strategy, with an inductive study approach, to enable an exploration of the phenomenon internal growth barriers. The study was conducted based on interviews with four founders of high-growth firms. Conclusion: The study has been able to identify four areas based on the founders' dictums, which had special significance for the emergence of internal growth barriers. The four areas can be developed to emerging growth obstacles if the high-growth firms do not consider their importance. This study suggests that the growth barriers most likely can be converted to growth potentials if the firms realize the importance to develop them.

Full textThis dissertation contributes to the research on young firms’ growth by analyzing two major issues, namely growth persistence and its impact on profits, where further theoretical development is needed and the empirical evidence is scarce and inconclusive. Based on Penrose’s approach, the resource-based view and evolutionary economics, this doctoral thesis examines (i) the relationship between firm growth and profits, (ii) the autocorrelation among young firms’ growth, and particularly, (iii) the growth persistence and the impact of growth on profits in the case of high-growth firms. Employing longitudinal panel data extracted from SABI©, this dissertation analyzes different cohorts of Spanish young firms from manufacturing and services sectors, during their earlier years of life. This thesis is organized upon three different papers, each one corresponding to one of the aforementioned objectives. The results of the first paper show that unlike some theories suggest, profits do not affect young firm growth whereas firm growth indeed enhances firm profits. Interestingly, these relationships are highly affected by intra- and inter-industry heterogeneity. The second paper indicates that young firm growth rates tend to exhibit a positive autocorrelation, that is, growth rates are persistent over time, which contrasts several previous studies. Nevertheless, as long as firm matures this positive correlation becomes more erratic, being the fifth year a turning point in a young firm growth path. The last paper, in turn, demonstrates that high growth firms are unlikely to sustain their high growth episode for more than one period and that these episodes show a slightly positive impact on subsequent profits. Additionally, this impact is higher if the high growth episode takes place once the firm surpasses its first few years. All these findings have important implications for theory development and future research on young firm growth, discussing previous theories in the light of the new empirical evidence.

Full textEmpresas gazelas têm sido alvo de muitos estudos dado o seu importante contributo para a economia. Elas são, segundo a OCDE, empresas com menos de cinco anos que, tendo um número mínimo de trabalhadores, atingem um crescimento anualizado de 20% ao ano durante três anos consecutivos. O objetivo deste trabalho é perceber se existem diferenças que distingam a estrutura de capital de empresas gazelas de empresas não gazelas. Mais especificamente, nós avaliamos se as gazelas apresentam maiores necessidades de capital e se as fontes de capital divergem entre os dois tipos de empresa. A fim de cumprimos o objetivo deste trabalho, utilizámos a base de dados "Central de Balanços" que é composta por dados de todas as empresas portuguesas criadas entre 2006 até 2015. Assim, identificámos cerca de 94 066 empresas não financeiras nascidas entre 2006 e 2011 das quais apenas 307 são gazelas. Os nossos resultados sugerem que as empresas gazelas obtêm valores mais elevados de capital total inicial, sugerindo que estas empresas têm maiores necessidades de financiamento do que as não-gazelas. A fim de financiarem as suas atividades, as gazelas tendem a usar mais capitais próprios do que dívida, uma vez que apresentam valores do rácio debt-to-capital inferiores às empresas não gazelas, mesmo considerando que a crise financeira e soberana influenciou a subida deste rácio para empresas nascidas entre 2008 e 2011.
Gazelle firms have been the center of many studies given their important contribution for the economy. According to OECD, they are firms with less than 5 years that, have a minimum number of employees, achieve an annualized growth of 20% a year for three consecutive years. The goal of this study is to understand the differences in the capital structure between gazelle and non-gazelle firms. More specifically, we evaluate if gazelle present higher financial needs and if the sources of financing differ from non-gazelle firms. In order to achieve this goal, we used the "Central de Balanços" database that includes data from all Portuguese firms from 2006 to 2015. Thus, we identify 94 066 non-financial firms born between 2006 and 2011, from those only 307 are gazelles firms. Our results suggest that gazelle firms raise higher amounts of initial capital, suggesting that these firms have higher financial needs than non-gazelle firms. To finance their activities, gazelle firms tend to use more internal funds, since they present lower debt-to-capital ratios, even considering that the financial and sovereign crisis tend to increase the D/C ratio for companies born between 2008 and 2011.

Full textEntrepreneurship has been object of encouragement in the world and in Brazil, given its significant contribution to the economic and social development of a nation. It is observed that the majority of companies, existing or new, are developing slowly and gradually; however, small share presents a different pattern, with high growth in sales or number of employees: they are the high growth firms (HGFs). These firms are responsible for a large part of job creation (Birch, 1981; Coad, Daunfeldt, Holzl, Johansson, & Nightingale, 2014, Henrekson & Johansson, 2010, OECD, 2010). This thesis aimed to identify the variables that help to explain the performance of HGFs in Brazil, according to OECD (2007) criterion. A survey with 470 Brazilian companies was conducted, collecting more than 30 categorical or metric predictor variables, used in the Logistic Regression model. Some identified variables were aligned to literature, but others less intuitive or documented. It was confirmed the increase in the probability of HGFs when they related to accelerators, received awards, or were spin-offs of other companies. As a consequence of the high banking interest rates and the entrepreneurship culture in Brazil, surprised the positive impact of bank loans and the entrepreneurs\' perception of trademark registration, as well as the negative impact of perception on advertising in digital media and donations from development institutions, related to HGFs. Additional analyzes with the subgroup of HGFs characterized as gazelles were made. Although it presents limitations of surveys and others, the thesis confirmed part of the results of the literature on entrepreneurship and identified avenues for future researches.

Full textThe purpose with this bachelor thesis is to explore how board of director diversity affects the firmfinancial performance for Swedish high growth firms listed in First North Growth Market. High growth firms stand for half of the work employment and production in high income countries and constitute therefore a significant role in society. During the current circumstances with the Covid-19 pandemic, the companies’ finances are affected and risk liquidation. A crucial factor for high growth firms to continue to grow and survive financial difficulties, is the composition of the board. Thereby this study’s focus is on diversity in the board and its effect on the firm financial performance in terms of ROA and Tobins Q for Swedish high growth firms. Furthermore, this study has implemented agent theory and The Upper Echelon Theory to create an understanding about the connection between the board’s composition, the firm financial performance and the decision-making process.The study is based on a quantitative research approach together with a positivist research philosophy, which makes it possible for the result to be generalized. The study’s data collection consists of 40 Swedish high growth firms listed in First North Growth Market. The result in this study shows that ROA was positively correlated with diversity in gender in the board. Further, the study’s results find no significant correlation between ethnicity, education and the firm financial performance.

Las universidades son incubadoras naturales de proyectos de empresa, que en muchos casos pueden contribuir a la mejora de la sociedad. El objetivo de las futuras investigaciones debe ir dirigido hacia la comprensión y el análisis de las características comunes que puedan ser extrapolables a otros ecosistemas, lo cual supone un importante reto ya que los ecosistemas emprendedores son únicos e irrepetibles.

El segon, es centra en les diferències de gènere dels emprenedors, identificant les motivacions que porten a les emprenedores i als emprenedors a crear una empresa i veure les possibles diferències. Les diferències de gènere més significatives apareixen en la forma d'afrontar la conciliació de la vida laboral i personal. Els resultats del tercer article, posen de manifest que les universitats poden tindre un paper determinant en la generació de futures empreses d'alt creixement. Així i tot, futures recerques han d'aportar més dades per a seguir definint un nou concepte, "spinup" o empresa gasela universitària, una empresa fundada en un ecosistema emprenedor universitari que es troba entre una startup i una spinoff. Les universitats són incubadores naturals de projectes que poden ajudar a solucionar reptes socials i millorar la societat.

Full textCompetition and technological change have never been as intense as they are today. To survive, companies must increasingly carry out current activities at the same time that they explore future ones. It is no easy task to operate on both of these fronts, and doing so is a potential source of tension and contradiction. Although management research has provided insight into the exploration and exploitation tension, there are still contradictions and unexplored areas. In particular, there is no consensus on the definition of the concepts of exploration and exploitation, which means the research lacks a certain level of consistency. In addition, there has been very little attention paid to the Exploration/Exploitation tension in the context of young, growing “scale-up” companies, which are particularly exposed to threats to their survival. To obtain a better understanding of the situations this tension causes in these companies, we have adopted a multi-paper dissertation consisting of three complementary studies.In the first study, to create a conceptual framework for the thesis, we answer researchers’ call for a clarification of the concepts of exploration and exploitation by proposing a typology of exploration. Then, based on a longitudinal, multi-case approach focused on eight scale-up companies, we first explore, in a second study, the factors influencing firms’ strategic orientations vis-à-vis exploration and exploitation activities. Finally, in the third study, we seek to understand how management teams define their individual roles with respect to exploration and exploitation activities

Full textENGLISH ABSTRACT: High Temperature Superconductors (HTS) exhibit exceptional electrical properties that make them attractive candidates for numerous electronic devices and applications. However, constructing working devices can be challenging due to fabrication difficulties of these brittle ceramics. This thesis investigates new methods to make the fabrication of high quality YBa2Cu3O7 (YBCO) thin films easier and compatible with more materials. We present the development of a universal add-on method that can be used in situ to improve the quality of superconducting thin films deposited by Pulsed Laser deposition (PLD). We investigate the in situ application of electric fields and voltage biasing to improve the thin film growth. Considering various electrode configurations, we have developed a final electrode design that is stable and produces reproducible results. By introducing an insulated high voltage (HV) electrode into the chamber during deposition, the quality of the deposited thin films can be modulated depending on the polarity of the voltage applied. Applying a positive voltage improves the film quality obtained. Applying a negative voltage degrades the superconducting properties of the films. A simple proof-of-concept HTS dual-mode microwave filter was designed, fabricated and tested. Only the filter produced using our novel PLD technique displayed the correct filtering action upon cooling to 77K. This is attributed to the thin films better superconducting properties due to our developed technique.

Ons toon die ontwikkeling van 'n algemene metode wat maklik bygevoeg kan word om in situ die gehalte van supergeleidende dun films, wat deur gepulseerde laser deponering (PLD) gedeponeer is, te verbeter. Ons ondersoek die in situ toepassing van elektriese velde en spannings om die dun film groei te verbeter. Verder oorweeg ons verskeie elektrode konfigurasies en ontwikkel 'n finale elektrode ontwerp wat stabiel is en herhaalbare resultate produseer. Die kwaliteit van die gedeponeerde dun films kan gemoduleer word deur die byvoeging van 'n geïsoleerde hoogspannings (HV) elektrode tydens deponering, afhangende van die polariteit van die aangelegde spanning. 'n Positiewe spanning verhoog die film kwaliteit, terwyl 'n negatiewe spanning die supergeleidende eienskappe van die films verlaag. 'n Eenvoudige HTS dubbele-modus mikrogolffilter is ontwerp, vervaardig en getoets, om as toepassings voorbeeld te dien. Slegs die filter wat geproduseer was met behulp van ons nuwe PLD tegniek, vertoon die beste filter oordrag by 77K. Dit word toegeskryf aan die beter supergeleidende eienskappe van die dun film, as gevolg van die toepassing van ons ontwikkelde tegniek.

Full textLos superconductores de alta temperatura (HTS) han liderado los programas de investigación y desarrollo durante tres décadas y actualmente se encuentran cerca de ser integrados, en aplicaciones de gran escala, en forma de cintas superconductoras (CCs), una arquitectura de cinta robusta y flexible que permite el crecimiento texturado de este material frágil. Un escollo pendiente para la amplia implementación de las CCs es el alto ratio de coste/prestación, esencialmente controlado por el crecimiento complejo y descelerado de la capa de HTS. En esta tesis, cogimos el reto de mejorar el rendimiento y coste de los métodos de crecimiento convencionales a través del desarrollo de una nueva técnica de crecimiento que combina la deposición de soluciones químicas (CSD), deposición del precursor inherentemente de bajo coste, con la alta velocidad de crecimiento, una aproximación de crecimiento de no equilibro que permite la formación de una fase líquida transitoria (Ba-Cu-O) que conduce a la cristalización del producto final: Crecimiento Asistido por Liquido Transitorio a través de CSD (TLAG-CSD). Hemos utilizado este proceso nuevo para crecer capas delgadas de YBa2Cu3O7-d (YBCO), un material HTS basado en cupratos de inigualables prestaciones bajo campos magnéticos aplicados y altas temperaturas. Estas propiedades tan impresionantes solo se pueden alcanzar si el compuesto, electrónicamente anisotrópico, exhibe una textura biaxial y contiene suficientes defectos para anclar a los vórtices. Por tanto, no solo pretendemos la comprensión de los fundamentos del proceso TLAG-CSD, sino también promover formas de crecimiento epitaxial a grandes velocidades, evitando las causas de degradación de la corriente, y fomentando el enriquecimiento de un paisaje adecuado para el anclaje de vórtices. Para afrontar estos retos, hemos combinado varios métodos avanzados de caracterización: Realizamos experimentos de crecimiento in-situ en una instalación de luz sincrotrón para evaluar la cinética de crecimiento a distintas presiones parcial y total de oxígeno, temperatura de crecimiento, rampa de calentamiento, grosor de la capa HTS y composición, así como la adición de nanopartículas (NP). La combinación de los distintos experimentos se ha resumido satisfactoriamente en los llamados diagramas de fase cinéticos, una representación visual de los procesos fuera del equilibrio y un roadmap para su utilización. Las capas de YBCO epitaxiales orientadas según el eje c se estudiaron minuciosamente con difracción de rayos-X, microscopía electrónica de transmisión (TEM), experimentos de transporte eléctrico a bajas temperaturas e inducción magnética para identificar las limitaciones y oportunidades del proceso. Ello incluyó estudiar la microstructura del YBCO y las propiedades eléctricas para evitar la reactividad del líquido con el sustrato, la segregación de fases secundarias, a la vez que asegurar la eliminación de CO2 y el dopaje de oxígeno de la estructura cristalina. Revelamos que con el método TLAG-CSD se pueden alcanzar velocidades de crecimiento epitaxial por encima de 100nm/s, sobrepasando dos órdenes de magnitud las técnicas convencionales utilizadas en la fabricación de CC (TFA-CSD/PLD/MOCVD). Las capas superconductoras alcanzaron un alineamiento epitaxial alto de los granos (Δω<0.6º y Δφ<1º), temperaturas críticas (Tc=88-92K) y densidades de corriente crítica competitivas (Jc(77K)=2-5MA/cm2). Además, clasificamos al proceso TLAG-CSD como altamente versátil para enriquecer el paisaje de anclaje de vórtices, no solo a través de la capacidad de promover una alta densidad de faltas de apilamiento y granos de YBCO orientados-ab muy pequeños (5-10nm) en las capas de YBCO, sino por su compatibilidad para formar nanocompuestos con la adición de nanopartículas preformadas.
High temperature superconductors (HTS) have been driving research and development programs for about three decades now and are on the verge of entering large scale utilization in the form of Coated Conductors (CCs), a robust and flexible tape architecture that enables textured growth of the rather brittle material class. A remaining bottleneck for widespread CC implementation is the high cost/performance ratio, essentially controlled by the complex and decelerating step of HTS layer growth. In this thesis we challenge the throughput and cost constraints of conventional growth methods through development of a novel growth technique that combines Chemical Solution Deposition (CSD), an inherently low-cost precursor deposition approach, with a high growth rate, non-equilibrium growth scheme that allows the formation of a transient (Ba-Cu-O) liquid phase prior to crystallization of the final product phase: Transient Liquid-Assisted Growth via CSD (TLAG-CSD). We employed the new process to grow YBa2Cu3O7-d (YBCO) thin films, a cuprate-based HTS material with unmatched current carrying performance in applied magnetic field conditions and at high temperatures. The unprecedented properties can only be reached if the electrically anisotropic compound exhibits biaxial texture and provides sufficient nanometric defects to pin vortices. Hence, not only is the fundamental understanding of the TLAG-CSD process required but also ways to promote epitaxial growth at high rates, avoidance of any current-degrading sources and strategies to enrich the pinning landscape. To tackle these challenges, we combined several advanced characterization methods: In-situ growth experiments at a synchrotron facility were carried out to follow growth kinetics under variation of total and oxygen partial pressures, growth temperatures, heating ramps, film thickness/composition and nanoparticle (NP) addition. The combined set of experiments was successfully summarized in the form of so-called kinetic phase diagrams, a visual representation of the out-of-equilibrium processes and a roadmap for its utilization. Epitaxial, c-axis oriented YBCO films were thoroughly studied via X-ray diffraction, transmission electron microscopy (TEM), low temperature electrical transport and inductive measurements to identify process related limitations and opportunities. This includes probing of the YBCO microstructuture and intrinsic electrical properties to avoid liquid induced substrate reactivity, segregation of secondary phases, while enabling proper CO2 elimination and oxygen doping of the crystal structure. We disclose that epitaxial layer growth rates above 100nm/s can be accomplished through the TLAG-CSD approach, surpassing conventional techniques used in CC manufacturing schemes (TFA-CSD/PLD/MOCVD) by up to two orders of magnitude. Superconducting films are demonstrated to reach high epitaxial grain alignment (Δω<0.6º and Δφ<1º), optimal critical temperatures (Tc=88-92K) and competitive critical current densities (Jc(77K)=2-5MA/cm2). We further classify the TLAG-CSD process as highly versatile in enriching the vortex pinning landscape, not only through its capability to promote a high density of stacking faults and small ab-oriented YBCO grains (5-10nm) in pristine YBCO films, but also through its compatibility with preformed nanoparticle addition in nanocomposites.

High-tech firms are among the fastest growing in the United States. The four industries with the most rapid growth -internet, software, semiconductors, and technology hardware - have almost doubled their share of industry output in the United States over the last decade. These firms are not only an important stimulus to the national economy but also have spawned new industries and spearheaded the development of innovative products and services. It is for these reasons that these firms are of particular interests to managers, investors, and academics. By examining these firms, researchers can help managers, investors, and academics better understand the attributes associated with firm growth. The purpose of this study was to determine whether any correlations existed between the size of the pre-IPO (initial public offering) venture fund and founder characteristics with firm growth. Twenty different high-tech firms were studied. These firms were divided into two different samples. One sample consisted of 10 firms that went public well before the 2000 recession and the other sample consisted of 10 firms that went public close to the 2000 recession. A 5 year time period beyond an IPO was used for calculating the firm's average growth rate. The results showed a negative correlation between the size of the pre-IPO venture funds and firm growth. No significant correlation between founder age and prior entrepreneurial experience of the founder with firm growth was found.
(cont.) As far as the prior relevant industry experience of the founder is concerned, an average experience of 6+ years was found to be positively correlated with firm growth. Even though, no correlation was found between founder education and firm growth; founders having a masters or a PhD degree outperformed those with a bachelor's or even a high-school degree. The results serve to provide contextual information to managers, investors, and academics who wish to consider their firm's growth potential or in general invest in high-tech firms. In addition, the study adds to the rich literature on the impact of pre-IPO venture funds and founder characteristics on firm success.

Full textTiivistelmä Kasvuyritykset ovat tärkeitä uusien työpaikkojen synnyttäjiä, ja teollistuneissa maissa niiden tukeminen on teollisuuspolitiikan keskiössä. Huolimatta laajasta yritysten kasvun tutkimustiedosta, merkittävistä julkisista investoinneista ja oletetuista hyvistä lähtökohdista kasvuyrittäjyydelle ei monella maantieteellisellä alueella kuitenkaan synny panostukseen verrattuna tarpeeksi kasvuyrityksiä. Tämä väitöskirja tutkii nopeasti kasvavien startup-yritysten syntymistä systeemisestä näkökulmasta. Yksittäisten yritysten sijaan tutkimuksessa määritellään tutkimuskohteeksi startup-teollisuus, kasvuhakuisiin startup-yrityksiin keskittyvä systeeminen talouden toimija, jolle annetaan tietty tehtävä talouden kehityksessä ja resurssiallokaatiossa. Startup-teollisuuden toimintaa eri konteksteissa tarkastellaan kokeellisen voittajayritysten rakentamisen prosessin avulla. Yritysten kasvua lähestytään lisäksi kriittisen realismin mukaisen kausaliteetin pohjalta. Tutkimuksen empiirinen osuus on toteutettu tapaustutkimuksena, jossa analysoidaan Suomen, Israelin ja Piilaakson startup-teollisuutta. Tutkimuskohteiden startup-yrityksiin liittyvien toimijarakenteiden ja instituutioiden kehitystä ja toimintaa analysoidaan kulttuuri-historiallisesta ja prosessuaalisesta näkökulmasta. Lisäksi kokeellisen voittajayritysten rakentamisen prosessin organisointia ja lopputuloksia analysoidaan usean vuosikymmenen ajalta sekä tapauskohtaisesti että niiden välillä. Tutkimustulokset esittävät kunkin startup-teollisuuden kehittävän ajan myötä tietyn kohteen omalle toiminnalleen. Tämä kohde, näkemys voittavasta startup-yrityksestä, linjaa koko startup-teollisuuden toimintaa. Tutkimalla tätä näkemystä voimme ymmärtää yritysten kasvun logiikoita systeemisellä tasolla, mikä mahdollistaa startup-teollisuuksien välisten rakenteellisten- ja suorituskykyerojen ymmärtämisen pitkällä aikavälillä. Tutkimuksen lopussa esitetään johtopäätöksiä poliittisen päätöksenteon kannalta

Full textI den här uppsatsen har en ekonometrisk analys genomförts i syfte att undersöka venture capitals påverkan på graden av uppkomsten av nya företag. Data samlades in från 32 OECD länder mellan åren 2006-2017, för att ta reda på hur TEA (total entrepreneurial activity) och TEA opportunity based påverkas av venture capital investeringar. I jämförelse med majoriteten av existerande litteratur, så ger resultaten av den här uppsatsen en mer nyanserad bild den rådande entusiastiska attityden gentemot venture capital. Då resultaten indikerar en mindre signifikant påverkan av venture capital investeringar än förväntat, bidrar den här uppsatsen till en viktig motpol till en gällande positiva inställningen till finansieringsformen. Dock stämmer andra resultat från uppsatsen överens med tidigare litteratur. Exempelvis är högt BNP signifikant med hög entreprenöriell aktivitet och höga skatter visar sig ha en avskräckande effekt. En annan intressant iakttagelse utifrån resultaten, är den subtila, men existerande skillnaden mellan TEA och TEA opportunity based. De indikerar att vidare och mer djupgående forskning bör göras på de två olika variablerna.
