Research

My ongoing research reflects my working experience from banking, and finance and my extensive network in the Norwegian finance industry. Several of my papers explore macroeconomic implications of financial behavior. Core research themes are:

Financial Risk management

Credit default modeling using closed form models, classic statistical regression models and Machine Learning (ML) models including explainable artificial intelligence (AI) methods. Estimating value at risk and volatility distributions.

Modelling financial prices and spreads

Examining efficiency in futures markets. Modeling bond spreads. Estimating term structure models for interest rates. Forecasting inflation using LSTM networks and various ML-models.

Other topics

Examining the banking business. Examining classic capital structure models of debt utilization decisions. Examining the asset liability problem for casualty insurers using stochastic programming/pricing put options on discrete output spaces. Economic models for controlling pollution.
