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...

The Empirical Risk-Return Relation : A Factor Analysis Approach

Ludvigson, Sydney C. - 2005

A key criticism of the existing empirical literature on the risk-return relation relates to the relatively small amount …, measures of conditional mean and conditional volatility--and ultimately the risk-return relation itself--will be misspecified … that three new factors, a "volatility," "risk premium," and "real" factor, contain important information about one …

Consumption Risk and International Asset Returns : Some Empirical Evidence

Cumby, Robert E. - 1987

The paper examines if real stock returns in four countries are consistent with consumption-based models of international asset pricing. The paper finds that ex-ante real stock returns exhibit statistically significant fluctuations over time and that these fluctuations cannot be explained by...

3D-PCA : Factor Models with Restrictions

Lettau, Martin - National Bureau of Economic Research - 2024

This paper proposes latent factor models for multidimensional panels called 3D-PCA. Factor weights are constructed from a small set of dimension-specific building blocks, which give rise to proportionality restrictions of factor weights. While the set of feasible factors is restricted, factors...

Digesting Anomalies : An Investment Approach

Hou, Kewei - 2012

Motivated from investment-based asset pricing, we propose a new factor model consisting of the market factor, a size factor, an investment factor, and a return on equity factor. The new factor model outperforms the Carhart four-factor model in pricing portfolios formed on earnings surprise,...

Sparse Modeling Under Grouped Heterogeneity with an Application to Asset Pricing

Cong, Lin William; Feng, Guanhao; He, Jingyu; Li, Junye - National Bureau of Economic Research - 2023

Sparse models, though long preferred and pursued by social scientists, can be ineffective or unstable relative to large models, for example, in economic predictions (Giannone et al., 2021). To achieve sparsity for economic interpretation while exploiting big data for superior empirical...

Estimating the Technology of Cognitive and Noncognitive Skill Formation

Cunha, Flavio - 2010

This paper formulates and estimates multistage production functions for children's cognitive and noncognitive skills. Skills are determined by parental environments and investments at different stages of childhood. We estimate the elasticity of substitution between investments in one period and...

Identification and Inference in Linear Stochastic Discount Factor Models with Excess Returns

Burnside, Craig - 2010

When excess returns are used to estimate linear stochastic discount factor (SDF) models, researchers often adopt a normalization of the SDF that sets its mean to 1, or one that sets its intercept to 1. These normalizations are often treated as equivalent, but they are subtly different both in...

Factor Model Forecasts of Exchange Rates

Engel, Charles - 2012

We construct factors from a cross section of exchange rates and use the idiosyncratic deviations from the factors to forecast. In a stylized data generating process, we show that such forecasts can be effective even if there is essentially no serial correlation in the univariate exchange rate...
