Predicting Student Dropout : A Replication Study Based on Neural Networks
Buchhorn, Jascha; Wigger, Berthold Ulrich - 2021
Using neural networks, the present study replicates previous results on the prediction of student dropout obtained with decision trees and logistic regressions. For this purpose, multilayer perceptrons are trained on the same data as in the initial study. It is shown that neural networks lead to...

Tackling Large Outliers in Macroeconomic Data with Vector Artificial Neural Network Autoregression
Polito, Vito; Zhang, Yunyi - 2021
We develop a regime switching vector autoregression where artificial neural networks drive time variation in the coefficients of the conditional mean of the endogenous variables and the variance covariance matrix of the disturbances. The model is equipped with a stability constraint to ensure...

Economic Determinants of Regional Trade Agreements Revisited Using Machine Learning
Blöthner, Simon; Larch, Mario - 2021
While traditional empirical models using determinants like size and trade costs are able to predict RTA formation reasonably well, we demonstrate that allowing for machine detected non-linear patterns helps to improve the predictive power of RTA formation substantially. We employ machine...

Inequality and the Zero Lower Bound
Fernández-Villaverde, Jesús; Marbet, Joël; Nuño, Galo; … - 2023
This paper studies how household inequality shapes the effects of the zero lower bound (ZLB) on nominal interest rates on aggregate dynamics. To do so, we consider a heterogeneous agent New Keynesian (HANK) model with an occasionally binding ZLB and solve for its fully nonlinear stochastic...
