Factor models, machine learning, and asset pricing

S Giglio, B Kelly, D Xiu - Annual Review of Financial Economics, 2022 - annualreviews.org
We survey recent methodological contributions in asset pricing using factor models and
machine learning. We organize these results based on their primary objectives: estimating …

Financial machine learning

Firm‐level climate change exposure

Z Sautner, L Van Lent, G Vilkov… - The Journal of …, 2023 - Wiley Online Library
We develop a method that identifies the attention paid by earnings call participants to firms'
climate change exposures. The method adapts a machine learning keyword discovery …

Autoencoder asset pricing models

S Gu, B Kelly, D Xiu - Journal of Econometrics, 2021 - Elsevier
We propose a new latent factor conditional asset pricing model. Like Kelly, Pruitt, and Su
(KPS, 2019), our model allows for latent factors and factor exposures that depend on …

[HTML][HTML] What greenium matters in the stock market? The role of greenhouse gas emissions and environmental disclosures

L Alessi, E Ossola, R Panzica - Journal of Financial Stability, 2021 - Elsevier
This study provides evidence on the existence of a negative greenium, ie a risk premium
related to the greenness of a firm, based on European individual stock returns. We define a …

Priced risk in corporate bonds

A Dickerson, P Mueller, C Robotti - Journal of Financial Economics, 2023 - Elsevier
Recent studies document strong empirical support for multifactor models that aim to explain
the cross-sectional variation in corporate bond expected excess returns. We revisit these …

Taming the factor zoo: A test of new factors

G Feng, S Giglio, D Xiu - The Journal of Finance, 2020 - Wiley Online Library
We propose a model selection method to systematically evaluate the contribution to asset
pricing of any new factor, above and beyond what a high‐dimensional set of existing factors …

Dissecting characteristics nonparametrically

J Freyberger, A Neuhierl… - The Review of Financial …, 2020 - academic.oup.com
We propose a nonparametric method to study which characteristics provide incremental
information for the cross-section of expected returns. We use the adaptive group LASSO to …

Asset pricing with omitted factors

S Giglio, D Xiu - Journal of Political Economy, 2021 - journals.uchicago.edu
Standard estimators of risk premia in linear asset pricing models are biased if some priced
factors are omitted. We propose a three-pass method to estimate the risk premium of an …

The virtue of complexity in return prediction

B Kelly, S Malamud, K Zhou - The Journal of Finance, 2024 - Wiley Online Library
Much of the extant literature predicts market returns with “simple” models that use only a few
parameters. Contrary to conventional wisdom, we theoretically prove that simple models …
