Empirical Applications of Entropy-based Inference Pubblico

Abstract

In the first chapter, I first propose two types of asymmetry measures which based on the tail distribution of the data instead of just the third moment-skewness for stock returns. With these new measures, greater tail asymmetries imply lower average returns in the cross section. In contrast, the relation between the skewness and the expected return is conditional. Then I discuss the relationship between asymmetries and several benchmark anomalies. Size and liquidity effects only appear among low upside asymmetry stocks, while momentum effect is getting stronger when upside asymmetry is increasing. In the second chapter, we examine the potential effect of naturalization on the U.S. immigrants' earnings. We find the earning gap between naturalized citizens and non-citizens is positive over many years, with a tent shape across the wage distribution. We focus on a normalized metric entropy measure of the gap between distributions, and compare with conventional measures at the mean, median and other quantiles. In addition, we further examine the potential sources of the earning gap, the "wage structure" effect and the "composition" effect. Both of these sources contribute to the gap, but the composition effect, while diminishing somewhat after 2005, accounts for about 3/4 of the gap. The unconditional quantile regression and conditional quantile regressions confirm that naturalized citizens have generally higher wages, although the gap varies for different income groups. In the last chapter, I propose linear and nonparametric models to predict crude oil price. Mainly, my forecast depends on three predictor variables, the change in crude oil inventories, its previous prices and product spread. By employing mean-squared prediction error (MSPE) and stochastic dominance (SD) tests, I find that the prediction result of our nonparametric models is significantly better than the random walk model, while the corresponding linear models' performance is better than the random walk model only for longer horizon forecasts (one to two years). And for the nonparametric model including all three predictors, I document MSPE reduction as high as 62.6% compared to the random walk model and the directional accuracy ratio as high as 77.5% at the two years horizon.
