Behavioral Finance - Asset Prices Predictability, Equity Premium Puzzle, Volatility Puzzle : The Rational Finance Approach

Rachev, Svetlozar T. - 2020

In this paper we address three main objections of behavioral finance to the theory of rational finance, considered as … “anomalies” the theory of rational finance cannot explain: (i) Predictability of asset returns; (ii) The Equity Premium; (iii … are the only possible explanations of the “anomalies”, but offer statistical models within the rational theory of finance …

Kelly, Bryan T.; Malamud, Semyon; Pedersen, Lasse Heje - 2020 - This version: June 8, 2020

We propose a new asset-pricing framework in which all securities' signals are used to predict each individual return. While the literature focuses on each security's own- signal predictability, assuming an equal strength across securities, our framework is flexible and includes...

Complexity in Factor Pricing Models

Didisheim, Antoine; Ke, Shikun; Kelly, Bryan T.; … - 2023

We theoretically characterize the behavior of machine learning asset pricing models. We prove that expected out-of-sample model performance—in terms of SDF Sharpe ratio and average pricing errors—is improving in model parameterization (or “complexity”). Our results predict that the best...

Inflation co-movement across countries in multi-maturity term structure : an arbitrage-free approach

Chen, Shi; Härdle, Wolfgang; Wang, Weining - 2015

Inflation expectation is acknowledged to be an important indicator for policy makers and financial investors. To capture a more accurate real-time estimate of inflation expectation on the basis of financial markets, we propose an arbitrage-free model across different countries in a...

Arbitrage-Free Nelson-Siegel Model for Multiple Yield Curves

Brignone, Riccardo; Gerhart, Christoph; Lütkebohmert, Eva - 2021

We propose an affine term structure model that allows for tenor-dependence of yield curves andthus for different risk categories in interbank rates, an important feature of post-crisis interestrate markets. The model has a Nelson-Siegel factor loading structure and thus economicallywell...

Sparse Multivariate Modeling for Stock Returns Predictability

Bernardi, Mauro; Bianchi, Daniele; Bianco, Nicolas - 2021

We develop a new variational Bayes estimation method for large-dimensional sparse vector autoregressive models with exogenous predictors. Unlike existing Markov chain Monte Carlo (MCMC) and variational Bayes (VB) algorithms, our approach is not based on a structural form representation of the...

Financial Machine Learning

Kelly, Bryan T.; Xiu, Dacheng - National Bureau of Economic Research - 2023

We survey the nascent literature on machine learning in the study of financial markets. We highlight the best examples of what this line of research has to offer and recommend promising directions for future research. This survey is designed for both financial economists interested in grasping...
