  1. 1. Probability Distortion in the relationship between Depression and Problem Gambling: A Mediation Analysis

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Chi Nguyen; David Johansson; [2021-08-04]
    Nyckelord :problem gambling; depression; probability distortion; mediation; probability weighting function; prospect theory;

    Sammanfattning : We posit that people with depressive symptoms are prone to problem gambling, and explore whether one possible driver of this is that depression increases misperception of probabilities. To test this hypothesis, we conducted a self-report survey on 230 regular gamblers recruited from Prolific. LÄS MER

  3. 2. Inverse probability weighted generalised estimating equations for longitudinal data

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Andrea Mattsson; [2021]
    Nyckelord :weighted generalised estimating equations; inverse probability weighting; longitudinal study; missing data; truncation by death; lung function; FEV1; Mathematics and Statistics;

    Sammanfattning : Longitudinal study designs, in which variables of interest are observed at multiple time points in a study population, are frequently used in clinical research. Missing data are common in these types of studies. Moreover, in studies investigating a population where the mortality rate is high, data can be truncated by death. LÄS MER

  4. 3. You Say You Want a Revolution - A Model on the Implications of Prospect Theory on Voting Behaviour

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Författare :Cristina Altomare; Agron Nuredini; [2018]
    Nyckelord :Prospect Theory; Voting Model; Uncertainty; Expectations; Disruption;

    Sammanfattning : In this thesis we create a voting model with a prospect theory foundation, introducing reference-dependent risk preferences, loss aversion, and probability weighting in the individual utility function. Classical voting models represent perfectly rational voters, we argue that voter behaviour can be better modelled by introducing prospect theory preferences, especially recent political trends.

  5. 4. Model-based Analysis of Individual Decision Making in the DNB Household Survey

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Shuai Guo; [2011]
    Nyckelord :prospect theory; Behavioral finance; model-based analysis; Business and Economics;

    Sammanfattning : Human financial decisions are known to deviate from ‘rational’, particularly under uncertainty and if time delays are involved. In the Nobel-winning prospect theory, Tversky and Kahneman showed that deviations from rational behavior were not only robust but also quite predictable, if considering average behavior in a population.
