1. INFLATION ANDINTEREST : What does high inflation imply?
University essay from Umeå universitet/NationalekonomiAbstract : 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.

2. A Borel-Cantelli lemma for non-stationary dynamical systems
University essay from Lunds universitet/Matematik LTHAbstract : In this thesis we present a Borel–Cantelli lemma for dynamical systems such that the dynamics driving the system varies with time. These results are largely based on a decomposition of transfer operators produced by Rychlik. Some limitations on the structure of sequences that is necessary for the results is given some discussion. READ MORE

3. Identifying Fundamental Characteristics of Shock Nonstationarity using MMS Measurements : Identifying and Distinguishing Non-stationary Behaviour Through the Magnetic Field Gradient in Quasi-perpendicular Shocks
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Collisionless shocks are widespread phenomena in the universe, and understanding the mechanisms behind their energy dissipation, with a rare number of collisions between particles, remains a significant unresolved question. The Earth’s bow shock provides an excellent opportunity to study this phenomena in situ. READ MORE

4. Tackling Non-Stationarity in Reinforcement Learning via Latent Representation : An application to Intraday Foreign Exchange Trading
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Reinforcement Learning has applications in various domains, but the typical assumption is of a stationary process. Hence, when this hypothesis does not hold, performance may be sub-optimal. READ MORE

5. Estimating the Market Risk Exposure through a Factor Model with Random Effects
University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakultetenAbstract : In this thesis, we set out to model the market risk exposure for 251 stocks in the S&P 500 index, during a ten-year period between 2011-04-30 and 2021-03-31. The study brings to light a model not often mentioned in the scientific literature focused on market risk estimation, the linear mixed model. READ MORE
