IPO underpricing is a researched phenomenon, with academics trying to understand its causes. This study investigates the potential explanations for this event, focusing on the Swedish market from 2000 to 2023. Using a dataset comprising 539 IPOs, including 253 technology firms, the analysis investigates how firm characteristics, market conditions, and sector affiliation influence first-day returns

This thesis investigates market inefficiencies in Chapter 11 bankruptcy stocks, focusing on whether short-term momentum can yield positive returns. Chapter 11 equities, characterised by minimal fundamental value and retail-driven speculation, offer a unique setting to examine behavioural biases and trading dynamics. A dataset of 40 stocks from 2012-2024 was employed to implement a momentum strateg

This study explores the overconfidence bias effect on stock market dynamics in Sweden and the US. Using an OLS model with lagged variables during the period 1996-2023, the findings reveal significant delayed effects of overconfidence on the Swedish stock market. Gender- adjusted overconfidence measure provides limited explanatory power, while the volatility index highlights the high correlation be

That an additional tariff of 25 percent could go unnoticed in global trade might seem unlikely, but the findings of this study suggest exactly that. Against the backdrop of escalating trade tensions between the EU and the US, this study examines both the immediate and short-term effects of the EU's temporary additional tariff of 25 percent on the import of exercise equipment. By focusing on th

This paper investigates the application of a Long Short-Term Memory (LSTM) model to construct a forward-looking risk factor for asset pricing. The LSTM model's predictions are utilized to create a novel risk factor, derived from long-short portfolios, offering an innovative approach to decomposing asset returns. For comparative analysis, the Fama-French three-factor (FF3) and Carhart four-fact

The thesis examines the impact of the Trump and Biden administrations on international trade relations and agreements, specifically comparing their trade policies. It explores how their contrasting approaches—Trump's protectionist stance versus Biden's multilateral cooperation—have influenced global trade dynamics through a mixed-methods approach for analysis. The research incorporates bot

Oil price forecasting is critical for financial markets, economic and geopolitical stability, and has a direct impact on the energy transition. Therefore, practitioners in the financial industry strive to understand the key drivers of the oil price and determine its best prediction model. This thesis investigates whether the exchange rates of oil-importing countries have predictive power in explai

The number of listed companies that decide to buy back their own shares has increased significantly in Sweden in recent years. This paper examines whether buybacks of companies listed on Nasdaq Stockholm have resulted in abnormal returns for the companies' shares. The study covers buybacks carried out during the period 2015 to 2024. The return is measured as the cumulative return from the da

Within the upcoming decade many countries have the ambition of banning the sale of new cars that emit carbon dioxide in order to reduce greenhouse gas emissions from the transport sector. Electric cars have been established as a key solution to combat climate change by replacing traditional internal combustion engine (ICE) vehicles which are being banned. To support the transition from ICE vehicle

This thesis explores the potential effects of universal basic income on labor supply and leisure allocation among employed individuals in Sweden. Grounded in the standard neoclassical labor-leisure framework, the study utilized an online survey targeting Swedish workers to investigate whether a monthly universal basic income of 12,208 SEK would reduce working hours and how individuals might reallo

This study investigates whether the amortization requirements introduced in Sweden in 2016 and 2018 have achieved their objectives, namely to reduce household debt ratios and dampen housing prices. The analysis is based on three hypotheses: the first examines the impact on the debt ratio, the second on housing prices, and the third explores whether the effects on housing prices vary across regions

This paper explores the impact of quantitative easing on debt in Sweden and the Euro area. The study examines the debt levels of both households and non-financial corporations and compares the results between Sweden and the Euro area. Using the historical balance sheets of the Riksbank and the European Central Bank, three hypotheses are tested using OLS time series regressions. The first hypothesi

The traditional assumption of normally distributed returns in portfolio optimization often fails to capture real-world complexities. This thesis investigates how higher moments – skewness and kurtosis – enhance portfolio optimization by addressing these complexities. Using polynomial goal programming and Bayesian shrinkage estimators, the study constructs and evaluates portfolios optimized for hig

Small and Medium – sized enterprises (SMEs) have historically underperformed against large enterprises in winning public procurement contracts both by measure of number of contracts and share of total contract value. Thus, both European Union and Swedish regulators have put forward recommendations on best practice to increase the presence of SMEs in public procurement. This study examines the impa

The integration of environmental, social, and governance (ESG) factors in investment decisions and corporate practices has gained momentum, reflecting the global focus on sustainability and ethical practices. This study investigates the relationship between ESG-scores and stock returns from 2019 to 2022 across three industry groups – manufacturing and raw materials, technology and media services,

This paper mainly focuses on the effect of cell unbalancing on the overall performance of a battery pack, as well as the challenges associated with designing a protection system for the Battery Management System (BMS). With the increasing trend towards fully electric aircraft, cars, buses, bikes, etc., the battery pack has become the sole power source for these vehicles. Consequently, it's imperat

Improvisation and Intention. Jazz musicians' views on improvisational cognitionIn previous research on jazz improvisation, questions about the role of intention seem to be subject to widely differing views. What role do intentions play in jazz improvisation? If the improviser has a conscious intention to play what is being played, is this simultaneous with the per­formance of it, or are intention

Fruit juices are widely consumed due to their affordability, nutritional value, and convenience. As global health consciousness rises, the fruit juice market is projected to grow from $153.17 billion in 2024 to $209.51 billion by 2029. Membrane processes, first introduced in the 1970s, have become essential in juice production, offering precise separation at low temperatures. The fruit juice indus

In recent years, it has been shown that deep eutectic solvents (DES) and similar mixtures solvate and allow for self-assembly of surfactants, serving as potential “green” alternatives as solvents for, for example, templating nanomaterials or drug delivery applications. Which surfactants are soluble and how they self-assemble depends strongly on the mixture components and their molar ratio. Her
