The estimation of multivariate GARCH time series models is a difficult task mainly due to the excessive parameterization exhibited by the problem, usually referred to as the "curse of dimensionality." For the VEC family, the number of parameters involved in the model grows as a polynomial of...

We show how to use asset market data to restrict the admissible region for the first-order autocorrelation of the stochastic discount factor (SDF). We interpret this statistic as a measure of a model's economic time variation across two periods. Estimating bounds for nominal and real SDFs at...

Asset returns implicitly contain information about the systematic and nonsystematic risks in an economy. Based solely on the law of one price condition, we extract this information by using a mean-variance frontier decomposition of returns, and exploit it to improve the assessment of...

This paper studies investor disagreement in the performance evaluation of equity mutual funds by comparing two existing approaches and estimating its relations with fund characteristics, active management level and fund flows. We find that investors disagree more about the performance of funds...

This paper investigates to what extent the U.S. presidential cycle can spillover across borders and affect the actions of global investors. Using data from 2000 to 2022 on G10 countries, we show that, on average, the annualized equity premium is 6.1% higher and the net monthly percentage equity...
