Hypertension remains a primary global driver of cardiovascular disease, yet traditional linear risk estimators struggle to capture non-linear physiological interactions, while complex machine learning ensembles often operate as opaque "black boxes." This thesis addresses this challenge by developing an interpretable machine learning framework and interactive what-if clinical dashboard su
Having endured sluggish growth and near-zero inflation rates for the past 30 years, inflation returned to Japan in 2022. This paper evaluates what influence monetary policy and supply shocks, respectively, had on the return. A 27 year span of quarterly data, from 1998 through 2025, was used to estimate the effects. Monetary policy shocks were modelled through an OLS-residual approach, and an impor
This study investigates how foreign asset accumulation affects economic growth in oil-rich countries, using a fixed effects panel regression on an unbalanced panel of 18 nations over the period 1970 to 2023. To examine how the growth effect of foreign asset accumulation varies with fundamental growth drivers, interaction terms with capital stock growth and TFP growth are included. The results show
Denna studie undersöker hur ägarstruktur påverkar europeiska fotbollsklubbars sportsliga prestationer och finansiella effektivitet. Mot bakgrund av den ökade kommersialiseringen inom europeisk fotboll och den växande debatten om supporterägande kontra privat ägande analyseras om olika ägarformer är förknippade med skillnader i sportslig framgång och resursanvändning. Studien baseras på en paneldat
Uppsatsen undersöker hur chocker i internationella olje-, gas- och kolpriser påverkar BNP-tillväxten i europeiska ekonomier 1990–2024. Genom att kombinera laggade import- och exportvolymer för olja, gas och kol med internationella energipriser konstrueras landsspecifika chockmått. Dessa mått används i panelregressioner med landsfasta och årsfasta effekter samt kontroller för styrränta och förändri
This thesis examines whether the Norwegian gender quota law affected corporate risk in publicly listed Norwegian firms. The reform introduced mandatory gender representation requirements for corporate boards, with requirements depending on board size. Based on Critical Mass Theory, Signaling Theory and Resource Dependence Theory, the study analyses whether the reform coincided with changes in corp
Denna uppsats analyserar hur allsvensk närvaro samt upp- och nedflyttningar påverkar kommunala utfall i svenska kommuner under perioden 2011–2024. Genom paneldata och fixed effects-modeller undersöks sambandet mellan allsvensk fotboll och sex utfallsvari- abler: flyttningsöverskott, gästnätter, nystartade företag, skattekraft, sysselsättning och anmälda sexualbrott. Resultaten indikerar att de dir
This paper examines whether a “December effect” exists in Swedish public finances, defined as a systematic increase in government expenditure at the end of the fiscal year. The analysis is motivated by the literature on “use-it-or-lose-it” incentives, where government agencies may face incentives to exhaust allocated budgets in order to avoid reductions in future appropriations. Using monthly pane
This thesis examines whether the timing of transposition of the Fourth Anti-Money Laundering Directive (AMLD4) into national law affected banks’ risk outcomes across member states in the European Union (EU). Using a panel dataset of 37 of the largest EU banks over the period 2010-2022, a Difference-in-Differences (DiD) framework is applied to compare changes in risk between banks in late and on-ti
This thesis examines whether tariff-related presidential Truth Social posts were associated with daily changes in implied stock market volatility during Donald Trump’s second presidential term. The analysis focuses on March 3 to June 30, 2025, a period marked by active tariff policy and frequent trade-related communication. Implied volatility is measured using daily close-to- close changes in the
Denna uppsats undersöker hur hushållens aktie- och bostadsförmögenhet påverkar hushållens konsumtion i Sverige på kort och lång sikt. Studien utgår från livscykelhypotesen och den permanenta inkomsthypotesen, där konsumtionen inte enbart antas bero på löpande inkomst utan även på hushållens samlade ekonomiska resurser. Analysen baseras på kvartalsdata för Sverige under perioden 1996–2023 och genom
Hierarchical portfolio allocation methods produce diversified portfolios while avoiding the instability of mean-variance optimisation. The framework depends on two separable choices: how assets are grouped and how capital is allocated across those groups. This thesis asks which of these choices matters more for out-of-sample portfolio performance. The empirical design crosses four linkage methods
This paper examines the relationship between implied stock market volatility and corporate credit spreads in the U.S. high-yield bond market. Previous research suggests that corporate credit spreads reflect more than expected default losses alone and are influenced by broader systematic risk conditions and changes in investor risk appetite. Using weekly data from January 2016 to December 2025, the
Under de senaste decennierna har den teknologiska utvecklingen accelererat samt möjliggjort en ökad automatisering av arbetsuppgifter i stora delar av ekonomin. I litteraturen betonas det att teknologi både fungerar som substitut och komplement till arbetskraften och leder till förändringar i strukturen på arbetsmarknaden. Särskilt har teorier som Skill Biased Technological Change (SBTC) och Routi
The purpose of this thesis was to examine income convergence across Swedish counties. We use data stretching from 2000-2024 in a cross-sectional regression with β-convergence as the traditional neoclassical approach to measuring income convergence. In contrast to previous studies on income convergence in Sweden during the twentieth century, our results lack evidence toward absolute convergence and
The socially optimal ticket price for public transport needs to first reflect operating costs and then the externalities would alter the price to match society’s best interests. The valuation of these externalities is inherently uncertain and remains an evolving field of study. This study serves as an initial investigation of what ideal fares would look like in Skåne County, Sweden. Four methods w
This thesis examines the relationship between the 2020 reduction in the capital requirement for private limited companies and the number of firm entries in Sweden. During the 2000s, two reductions in the capital requirement have been implemented, whereas the most recent reduction has not yet been evaluated. Theoretically, a lower cost of establishing a firm is expected to reduce the threshold for
This thesis investigates whether industry-level cloud adoption is associated with labour productivity in Swedish unlisted firms during 2014-2024. The empirical analysis uses a two-way fixed effects model applied to firm panel data, combining firm financials from Retriever Business with cloud adoption rate from Eurostat’s ICT survey across 24 NACE divisions. Our main result shows a small within-fir
This paper investigates whether increased exports to China are negatively associated with economic growth and structural development in Latin America. The relationship is compared with the corresponding association for exports to the United States and the European Union. A series of panel regressions are performed using data on export shares, GDP per capita growth, manufacturing value added (% of
This study examines whether sustainable U.S companies experienced abnormal returns in connection with the entry into force of the Paris Agreement on November 4, 2016, and whether variations in abnormal returns can be explained by differences in environmental performance. The sample consists of U.S companies belonging to the upper 30th percentile of “environmental score” (E-score), where E-score is
