The impact of the increase in the minimum wage on inequality and employment

This report analyses, through the use of MCVL microdata, the relationship between the increase in the Minimum Interprofessional Wage (SMI) for 2019 and inequality, both in terms of wages and income, as well as its impact on employment. The results confirm that the groups most affected by this increase are women, young people and immigrants. A reduction in wage inequality and an increase in the income share of the lowest quintiles are observed, which would suggest that the increase in the minimum wage has fulfilled its objective of wage compression. On the other hand, this measure has a limited negative causal impact on employment, nil in the short term but growing slightly and gradually over time, mainly in terms of job losses and, to a lesser extent, an adjustment in the labour intensity of those affected.

La valoración del bienestar social

Este trabajo aborda la valoración del bienestar social y su relación con la utilidad individual, con el propósito de que resulte accesible a los no especialistas. Nos centramos en la valoración del bienestar social desde el punto de vista del procedimiento, más que del concepto. Los elementos relevantes serán pues las alternativas sociales y las valoraciones de los individuos. Describimos las dificultades que aparecen a la hora de construir una función de bienestar social a partir de las valoraciones individuales y también consideramos las posibilidades que se abren cuando definimos una función de evaluación social directamente sobre las alternativas sociales, sin pasar por las valoraciones individuales. El trabajo incluye cuatro aplicaciones a diferentes campos: desigualdad, mercado de trabajo, desarrollo humano y pobreza.

The negative impact of ICT overuse on student performance: evidence from OECD countries

The increasing presence of technologies at school has triggered a vivid debate on the way ICT influences students’ learning process. Using PISA 2018 data for 15-year-old students and hierarchical linear models, we find an inverted U-shaped relationship between ICT use at school and students’ performance in mathematics in 22 OECD countries. In all cases, the excessive use of technology is associated with a lower academic performance, although this penalty differs across countries, which points to the importance of addressing country-specific analyses. The differentiated profile of those very intensive users, who suffer from above-average bullying exposure, draws into question whether the effect can be deemed as causal. Based on Inverse Probability Weighting techniques, the findings indicate that the very intensive use of ICT at school causes an underperformance of students equivalent to around half an academic course in Estonia, Finland and Spain. The results highlight the need to ensure that the integration of ICT at schools is based on well-founded pedagogical methodologies; frequently evaluated; and supported by the continuous update of teachers’ digital skills.

Internship contracts in Spain: a stepping stone or a hurdle towards job stability?

Internship contracts (ICs) were designed as a stepping stone for educated young work- ers to develop their professional skills upon graduation. Such contracts incentivise employment creation, as firms benefit from lower wages and tax reductions, but at the same time, firms are expected to develop training programmes to improve the profes- sional skills of youth. This paper assesses whether such subsidies help improve the labour market trajectories of the beneficiaries of ICs. To do so, we focus on entrants into the labour market and compare those who start through an IC with a matched control group whose first employment episode is through a nonsubsidised temporary contract. We look at short, medium and long-term effects on job stability and wages. We find that in the short run, labour market performance, in terms of wages and job stability, is poorer for the beneficiaries of the IC, unless they leave the firm right after the IC experience. In the medium and long run, however, the negative impact on wages is mitigated, and its impact on job stability is positive. A possible interpretation is that firms, in the short run, use ICs to lower hiring costs, but beneficiaries send a positive signal to the market that is rewarded in the medium and long terms.
