The Working Paper Series seeks to disseminate original research in economics and finance. All papers have been anonymously refereed. By publishing these papers, the Banco de España aims to contribute to economic analysis and, in particular, to knowledge of the Spanish economy and its international environment. The opinions and analyses in the Working Paper Series are the responsibility of the authors and, therefore, do not necessarily coincide with those of the Banco de España or the Eurosystem.

Traditional measures of labor quality might have the shortcoming of missing some features of the very important increase in labor utilization within European countries. In particular, we explore the case of Spain. Despite showing one of the most important increases in labor quality in the EU according to standard methods, it also presents a negative TFP growth. The paper shows the importance of considering—on top of observed changes in the composition of the labor force by gender, age, education, tenure, and nationality—changes in both average and relative productivities of those abovementioned socio‐demographic groups over time. We first use a time varying weight index in order to capture the decrease in relative productivities across characteristics. Once this issue is considered the estimated growth of labor quality decreases notably and the index becomes flat between 2002 and 2006. We relate this slowdown to the increasing over‐education of the Spanish workforce in the recent past. We then incorporate a selection model into the labor force. We argue that in the recent past there has been a massive entry of workers with below average unobserved abilities, generating a decrease in quality of labor. Indeed labor quality slightly decreased from 1995 onwards (always increasing without the selection model).

Income per capita in Spain relative to that of other advanced EU countries held stable at around 90% from 2000 to 2016. Stagnant labour productivity is at the root of this lack of convergence. This paper examines these developments from a sectoral perspective based on recently released EU KLEMS data. Our main findings are as follows: i) Spain has lower productivity levels vis-à-vis other EU countries in most sectors, with only 4 out of 23 sectors exhibiting higher productivity in Spain: accommodation and food services, agriculture, electricity and gas supply, and information and communication services; moreover, the allocation of employment towards low-productivity sectors accounts for half of the aggregate Spain-EU productivity gap in levels; ii) turning to the changes in the 2000-2016 period, the overall lack of convergence is driven by a divergence in productivity relative to EU countries, especially within services sectors; iii) while both ICT (Information and Communication Technology) and non-ICT capital in Spain converged towards European levels, Total Factor Productivity (TFP) divergence in most sectors explains the lack of convergence in labour productivity. Finally, we explore one potential explanation for this pattern: the TFP divergence and ICT capital convergence can be rationalised in the presence of complementarities between ICT-capital and labour force skills. Indeed, our industry-country regression analysis suggests that the dismal performance of Spanish TFP might be related to the significant deficit in the population's skills as proxied by PIAAC-OECD scores.

This paper presents an estimate of the Spanish economy's potential growth. This estimate is based on a production function methodology that includes certain refi nements on previous versions and generates less procyclical potential output growth estimates than those traditionally considered in the literature. As a result, the (positive) output gap estimated in expansions is higher and that estimated in recessions is lower. According to these results, given the available population projections and under the assumption that total factor productivity (TFP) and structural unemployment will behave in line with historical patterns, the Spanish economy's potential growth is expected to recover gradually over the coming years but, in line with projections by international organisations, to lower rates than those in the expansion period. However, per capita growth rates fully recover to the pre-crisis levels, which highlights the importance of population projections in shaping the Spanish potential growth.
