A hands-on machine learning primer for social scientists : math, algorithms and code
Askitas, Nikos - 2024
This paper addresses the steep learning curve in Machine Learning faced by noncomputer scientists, particularly social scientists, stemming from the absence of a primer on its fundamental principles. I adopt a pedagogical strategy inspired by the adage "once you understand OLS, you can work your...

IC technology and learning : an impact evaluation of cl ssi2.0
Checchi, Daniele; Rettore, Enrico; Girardi, Silvia - 2015
In this paper we present a counterfactual evaluation of the effect of ICT resources at school on student achievements conducted in Italy. In 2009 156 classes at 6th grade were endowed with additional resources earmarked for purchasing ICT equipments only. By selecting an equivalent number of...

Distance learning in higher education : evidence from a randomized experiment
Cacault, Maria Paula; Hildebrand, Christian; … - 2019
Using a randomized experiment in a public Swiss university, we study the impact of online live streaming of lectures on student achievement and attendance. We find that (i) students use the live streaming technology only punctually, apparently when random events make attending in class too...

Isolating the "Tech" from EdTech : experimental evidence on computer assisted learning in China
Ma, Yue; Fairlie, Robert W.; Loyalka, Prashant; … - 2020
EdTech which includes online education, computer assisted learning (CAL), and remote instruction was expanding rapidly even before the current full-scale substitution for in-person learning at all levels of education around the world because of the coronavirus pandemic. Studies of CAL...

The speed of employer learning and job market signaling revisited
Habermalz, Steffen (contributor) - 2006
This paper discusses the claim made in Altonji and Pierret (1997) and Lange (2005) that a high speed of employer learning indicates a low value of job market signaling. The claim is first discussed intuitively in light of Spence’s original model and then evaluated in a simple extension of a...

The rate of learning-by-doing : estimates from a search-matching model
Prat, Julien (contributor) - 2007
We construct and estimate by maximum likelihood an equilibrium search model where wages are set by Nash bargaining and idiosyncratic productivity follows a geometric Brownian motion. The proposed framework enables us to endogenize job destruction and to estimate the rate of learning-by-doing....

Exploring the causes of frictional wage dispersion
Tjaden, Volker; Wellschmied, Felix - 2012
Standard search models are unreliable for structural inference of the underlying sources of wage inequality because they are inconsistent with observed residual wage dispersion. We address this issue by modeling skill development and duration dependence in unemployment benefits in a random on...

Asymmetric information between employers
Kahn, Lisa B. - 2013
Employer learning about workers' abilities plays a key role in determining how workers sort into jobs and are compensated. This study explores whether learning is symmetric or asymmetric, i.e., whether potential employers have the same information about worker ability as the incumbent firm. I...
