  1. 6. Detecting Fraudulent User Behaviour : A Study of User Behaviour and Machine Learning in Fraud Detection

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Analys och partiella differentialekvationer

    Författare :Patrik Gerdelius; Sjönneby Hugo; [2024]
    Nyckelord :Fraud Detection; User Behaviour; Random Forest; PCA; SMOTE;

    Sammanfattning : This study aims to create a Machine Learning model and investigate its performance of detecting fraudulent user behaviour on an e-commerce platform. The user data was analysed to identify and extract critical features distinguishing regular users from fraudulent users. LÄS MER

  3. 7. Bonus Slopus: Examining the Effect of Removing Bonus Incentives for Electric Vehicles on Adoption

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Författare :Axel Eisner Sjöberg; [2024]
    Nyckelord :BEV; ICEV; Climate Change Mitigation; Incentives; Bonus Malus;

    Sammanfattning : In the global battle against climate change, the pursuit of sustainable transportation, particularly through the adoption of electric vehicles (EVs), has become a central focus. This thesis investigates the specific case of Sweden and delves into the repercussions of removing the climate bonus subsidy for EVs, exploring its immediate and potential long-term impacts on the market.

  4. 8. Temperature Shocks and Price Stability

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Författare :Klara Strömberg; [2024]
    Nyckelord :Climate Change; Price Stability; Local Projections; United Kingdom;

    Sammanfattning : This thesis investigates the interplay between temperatures and prices in an advanced economy context. To this end, I estimate the impulse response to a 1°C temperature anomaly on the UK economy. LÄS MER

  5. 9. Applications of Random Walks : How Random Walks Are Used in Wilson's Algorithm and How They Connect to Electrical Networks

    Master-uppsats, Uppsala universitet/Sannolikhetsteori och kombinatorik

    Författare :Erik Jonsson; [2024]
    Nyckelord :Random Walks; Wilson s Algorithm; Electrical Networks; Pòlya s theorem;

    Sammanfattning : In this master thesis we will show how random walks are used in Wilson's algorithm to generate spanning trees of graphs, and how they can be used to calculate the number of spanning trees in a graph. We will also explore the connection between electrical networks and random walks, and how this connection can be exploited to prove Pólya's theorem (normally proved with probability and combinatorics) using electrical arguments.

  7. 10. INFLATION ANDINTEREST : What does high inflation imply?

    Magister-uppsats, Umeå universitet/Nationalekonomi

    Författare :Hugo Sjövall; [2024]
    Nyckelord :;

    Sammanfattning : The objective of this paper is to examine the general relationship between the year-onyear inflation-rate and nominal interest rates, contributing to a better understanding of what high inflation implies for nominal rates. Although a heavily researched topic, economists still seem far from a consensus regarding the relation between these two variables; some papers suggest a strong relationship – while others reject the idea of an empirically observable relationship altogether.
