More investment in Research and Development for better Education in the future?

TL;DR

This paper investigates whether increased R&D investment causally improves education performance, finding a long-term positive effect on PISA scores that manifests after at least a decade of sustained investment.

Contribution

It demonstrates a causal link between R&D investment and education outcomes using Bayesian Networks and longitudinal data analysis.

Findings

R&D investment positively affects education performance.

The effect on PISA scores appears after at least 10 years.

Long-term R&D investment is crucial for educational improvement.

Abstract

The question in this paper is whether R&D efforts affect education performance in small classes. Merging two datasets collected from the PISA studies and the World Development Indicators and using Learning Bayesian Networks, we prove the existence of a statistical causal relationship between investment in R&D of a country and its education performance (PISA scores). We also prove that the effect of R\&D on Education is long term as a country has to invest at least 10 years before beginning to improve the level of young pupils.
