Relationen mellan ekonomisk tillväxt, FDI och humankapital : En empirisk studie med fokus på OECD-länder / The relationship between economic growth, FDI and human capital : An empirical study with focus on the OECD-countries

Andersson, Anja, Samardzic, Selma January 2022 (has links)
Syftet med denna studie är att undersöka hur nivån på humankapital i ett land kommer att påverka effekten av utländska direktinvesteringar på ekonomisk tillväxt. Studien omfattar 31 OECD-länder under tidsperioden 1989-2020. FDIs inverkan på ekonomisk tillväxt undersöks i en multipel regressionsmodell med paneldata där fokus ligger på samspelet mellan utländska direktinvesteringar och utbildning (en proxy för humankapital). Det teoretiska ramverket är huvudsakligen fokuserat på Romers endogena tillväxtteori och institutionell teori. Resultatet av den multipla regressionsmodellen visar att utländska direktinvesteringar som en enskild variabel har en positiv effekt på ekonomisk tillväxt. Samspelet mellan utländska direktinvesteringar och humankapital visade sig ha en negativ effekt på den ekonomiska tillväxten. Resultatet av humankapitalet som en enskild faktor visade sig dock vara positivt i förhållande till ekonomisk tillväxt. Resultatet av studien indikerar att utländska direktinvesteringar som en oberoende faktor har en positiv inverkan på den ekonomiska tillväxten samt humankapital som en oberoende faktor. Resultatet tyder på att en hög nivå på humankapitalet i ett land attraherar inte tillräckligt mycket utländska direktinvesteringar för att ha en positiv effekt på den ekonomiska tillväxten. / The purpose of this study is to examine how the level of human capital in a country will influence the effect FDI has on economic growth. The study covers 31 OECD-countries during the time period 1989-2020. The impact of FDI on economic growth is examined in a multiple regression model with panel data where the focus is on the interaction between FDI and education (a proxy for human capital). The theoretical framework is mainly focused on Romer’s endogenous growth theory and institutional theory. The result of the multiple regression model shows that FDI as a single variable has a positive effect on economic growth. The interaction between FDI and human capital was shown to have a negative effect on economic growth. However, the result of human capital as a single factor was proved to be positive in relation to economic growth. The results indicate that a high level of human capital in a country does not attract enough foreign direct investment to have a positive effect on economic growth.

An Application of an In-Depth Advanced Statistical Analysis in Exploring the Dynamics of Depression, Sleep Deprivation, and Self-Esteem

Gaffari, Muslihat 01 August 2024 (has links) (PDF)
Depression, intertwined with sleep deprivation and self-esteem, presents a significant challenge to mental health worldwide. The research shown in this paper employs advanced statistical methodologies to unravel the complex interactions among these factors. Through log-linear homogeneous association, multinomial logistic regression, and generalized linear models, the study scrutinizes large datasets to uncover nuanced patterns and relationships. By elucidating how depression, sleep disturbances, and self-esteem intersect, the research aims to deepen understanding of mental health phenomena. The study clarifies the relationship between these variables and explores reasons for prioritizing depression research. It evaluates how statistical models, such as log-linear, multinomial logistic regression, and generalized linear models, shed light on their intricate dynamics. Findings offer insights into risk and protective factors associated with these variables, guiding tailored interventions for individuals in psychological distress. Additionally, policymakers can utilize these insights to develop comprehensive strategies promoting mental health and well-being at a societal level.

Do More Females In Power Generate Economic Growth? : Panel data analysis of female parliamentary representation and economic growth in the West, Russia and Central Asia

Skog, Viktor, Dahl, Marcus January 2024 (has links)
The purpose of this paper was to analyze the effect of representation of women in parliamentsand economic growth in three different regions. The regions which were analyzed wereEurope, Latin America, Russia and Central Asia. Based on previous research’s results, thequestion whether women in parliamentary settings affect economic growth and wealth wasexamined. A regression model adapted to panel data analysis was used on data obtained fromreliable sources like the World Bank and the UN. The variables used in the regression modelwere real GDP per capita, real GDP per capita growth, share of females in parliamentarypositions, trade, investment and Women, Business and the Law index (WBL). Justification ofthe variables are based in previous research which alludes to theoretical economicalframeworks. This study contributes to the institutional variable of the WBL indicator. Due tothe scale of the study, the results have varied across different regions, but the overall relationbetween women in power and economic growth was deemed positive. Explicit normsregarding accessibility to economical, political and judicial institutions have a greater impacton real GDP per capita than female parliamentary representation.

Configuring political relationships to navigate host-country institutional complexity: Insights from Anglophone sub-Saharan Africa

Boso, N., Amankwah-Amoah, J., Essuman, D., Olabode, Oluwaseun E., Bruce, P., Hultman, M., Kutsoati, J.K., Adeola, O. 05 December 2022 (has links)
Yes / We examine how ties with multiple host-country political institutions contribute to MNE subsidiary performance in countries with weak formal institutions. We suggest that forging relationships between subsidiaries and host-country government actors, local chieftains, and religious leaders generates regulative, normative, and cultural-cognitive political resources. We integrate institutional and configuration theories to argue that similarity to an ideal configuration of the three political resources contributes to MNE subsidiary performance, and that the more dysfunctional host country institutions, the greater the impact on performance. We test our hypotheses using primary and archival data from 604 MNE subsidiaries in 23 Anglophone sub-Saharan African countries and find support for our hypotheses. In our conclusion we discuss the wider theoretical, managerial, and public policy implications of our findings.

Termisk analys av stadsmiljön : En fallstudie av urban värmeöeffekt i Linköping / Thermal analysis of the urban environment : A case study of the urban heat island effect in Linköping

Karlsson, Linda January 2024 (has links)
Different environments exhibit varying temperatures, where generally areas with high amounts of vegetation, and consequently significant shading, tend to be cooler than regions dominated by dark buildings and black roofs. As a result, urban areas are generally expected to have higher temperatures in comparison to rural areas or forests. This phenomenon, known as urban heat island effect, can be visualized as a dome-shaped area of hot air that concentrates pollution and can influence the precipitation patterns of a region. This study aimed to examine the urban heat island effect in Linköping from 1984 to 2023, with a focus on analyzing the correlation between the prevalence of impermeable materials and changes in surface temperature using remote sensing and geographic information systems. The study also explored the potential for predicting surface temperatures in 2034 with spatial regression. The results indicated a close relationship between the extent of impermeable materials (indicative of urban land use) and the surface temperatures in Linköping over the study period. Both urban land use and areas with high surface temperatures increased from 1984 to 2023, independent of rising air temperatures. The geographic locations of high urban heat island values have remained largely unchanged over time, but their spatial distibution expanded from 1984 to 2023. The predictive analysis has demonstrated the possibility to predict surface temperatures in 2034, with emphasis on the pivotal role of the model and its explanatory variables. The final predictive model indicates a continuing upward trend in surface temperatures. This study has in summary added an extensive overview of the urban temperature changes in Linköping, identifying potential areas with particularly high surface temperatures historically and provided possible models for predicting trends in the future. / Olika miljöer uppvisar varierande temperaturer, där generellt områden med mycket vegetation, och därmed betydande skuggning, tenderar att vara svalare än regioner dominerade av mörka byggnader med svarta tak. Följaktligen förväntas urbana områden generellt ha högre temperaturer jämfört med landsbygdsområden eller skogsområden. Detta fenomen, känt som urban värmeöeffekt, kan förklaras som ett kupolformat område med förhöjda temperaturer som koncentrerar föroreningar, och som kan påverka regionala nederbördsmönster.  Denna studie syftade till att undersöka den urbana värmeöeffekten i Linköping från 1984 till 2023, med fokus på att analysera korrelationen mellan förekomsten av ogenomträngliga ytor och förändringar i yttemperatur med hjälp av fjärranalys och geografiska informationssystem. Landsat-satellitbilder har använts för att erhålla data för markanvändning/marktäcke, samt för markytans temperaturer under studieperioden. Studien undersökte också möjligheten att förutsäga yttemperaturer år 2034 med hjälp av två enkla prediktiva modeller i programvaran ArcGIS Pro: Multiskalig Geografiskt Viktad Regression (MGWR) och Forest-baserad Forecast.  Resultatet visade en nära relation mellan omfattningen av ogenomträngliga ytor (indikerade som urban markanvändning) och yttemperaturen i Linköping under studieperioden. Både urban markanvändning och områden med höga yttemperatur ökade från 1984 till 2023, oberoende av ökade lufttemperaturer. De geografiska positionerna för höga värmeövärden förblev i stort sett oförändrade över tid, men deras rumsliga fördelning expanderade från 1984 till 2023. Den prediktiva analysen visade att MGWR-modellen uppvisade begränsningar med de valda variablerna och dess samband till varandra. Däremot gav Forest-baserad Forecast-modellen ett mer tillförlitligt resultat, genom att utnyttja historiska yttemperaturer och data om markanvändning och marktäcke. Yttemperaturkartan för 2034 som generades av den senare modellen förutspår en ökning av områden med höga yttemperaturer (mellan 41 och 45 grader Celsius), och en bredare fördelning av temperaturer mellan 31 och 40 grader Celsius. Den prediktiva modellen indikerar en fortsatt uppåtgående trend i yttemperaturer. Sammanfattningsvis ger denna studie en omfattande översikt över urbana temperaturförändringar i Linköping, och identifierar potentiella områden med särskilt höga yttemperaturer historiskt och ger förslag för möjliga metoder för att förutsäga trender i framtiden.

跨國新產品銷售預測模式之研究-以電影為例 / Models Comparing for Forecasting Sales of a New Cross-National Product - The Case of American Hollywood Motion Pictures

李心嵐, Lee, Hsin-Lan Unknown Date (has links)
現今市場競爭愈來愈激烈,迫使廠商紛紛至海外尋求產品消費市場,在跨國銷售的背景之下,需要有更多可以確定國家選擇、預測銷售及估計需求的方法。而其中可以滿足這些需求的方法之中,就是研究產品跨國擴散型態,藉以瞭解後進國家與領先國家中新產品如何擴散且會如何互相影響 (Douglas and Craig, 1992)。 在眾多的跨國產品中,本研究選擇好萊塢電影做為實證分析的對象。 經由集群分析,本研究發現(一)台灣高首週票房且口碑佳的電影,會遇到假日人潮、有很高的美國總票房、以及很高的美國首週票房;(二)美國影片在美國及台灣映演的每週票房趨勢有差異存在;(三)片商沒有做好影片在台灣映演的檔期歸劃;(四)三群電影中,在影片類型沒有明顯地區別。 經由十二個新產品銷售預測模型的建立:對數線性迴歸模式(LN-Regression Model)(不考慮新產品領先國擴散經驗)(以OLS估計)、卜瓦松迴歸模式(Poisson Regression Model) (不考慮新產品領先國擴散經驗)(以MLE估計)、負二項分配迴歸模式(Negative Binomial Distribution Regression Model) (不考慮新產品領先國擴散經驗)(以MLE估計)、Exponential Decay模式(以OLS估計)+迴歸方程式體系(不考慮新產品領先國擴散經驗)(以SUR估計)、Exponential Decay模式(以OLS估計)+迴歸方程式體系(考慮新產品領先國擴散經驗)(以SUR估計)、Exponential Decay模式+層級貝氏迴歸模式(考慮新產品領先國擴散經驗)、Bass連續型擴散模式(以NLS估計)+迴歸方程式體系(不考慮新產品領先國擴散經驗(以SUR估計)、Bass連續型擴散模式(以NLS估計)+迴歸方程式體系(考慮新產品領先國擴散經驗(以SUR估計)、Bass離散型擴散模式(以OLS估計)+迴歸方程式體系(不考慮新產品領先國擴散經驗)(以SUR估計)、Bass離散型擴散模式(以OLS估計)+迴歸方程式體系(考慮新產品領先國擴散經驗)(以SUR估計)、層級貝氏BASS離散型擴散模式+迴歸方程式體系(不考慮新產品領先國擴散經驗)(以SUR估計)、層級貝氏BASS離散型擴散模式+迴歸方程式體系(考慮新產品領先國擴散經驗)(以SUR估計)。本研究發現:(一)在考慮影響後進國的新產品擴散速度時,領先國的擴散經驗為絕對必要的考慮因子;(二)必須使用Bass連續型擴散模式做為建構新產品銷售預測模型的基礎;(三)必須使用Bass連續型擴散模式的NLS估計法估計Bass模型的創新係數p、模仿係數q及市場潛量m。

台灣股市中下市公司之預測–歷史事件研究法

蘇凡晴 Unknown Date (has links)
本論文主要目地是在研究財務比率對上市公司發生下市事件之預測。我們運用歷史事件研究法和Cox迴歸模型去研究上市公司發生下市事件之原因。同時,我們也針對Cox迴歸模型和Logit模型在發現對下市事件有顯著影響的財務比率作比較。 / This study applies the event history analysis and the Cox regression model to examine the causes of firm delisting, and also compares the performance of the Cox regression model with that of the logit model in detecting factors that have a statistically significant impact on the delisting event. The empirical results show that the hazard rate of firm delisting increases with the ratio of current liabilities to current assets, a binary variable indicating if the total liabilities of a firm is greater than its total assets, and a binary variable indicating if the net income of a firm was negative for the last two quarters, while the hazard rate of firm delisting decreases with increases in the firm size and the ratio of funds provided by operations to total liabilities.
