1. Introduction

Background

Relevant literature focused on inequalities in developed countries.

Explanations based on market forces -technology, international trade, returns to education- (versus institutional features) that refers to ‘unaivodable’ labour market issues.

Relevant amount of literature focusing on employment polarisation (David Autor, Alan Manning, Erik Olin Wright, Eurofound…) across Economics, Sociology, Industrial Relations, etc.

“Quality”

Employment

Computerization allows subsituting middle-skilled jobs (with high-routine content) by machines.

Low-skilled and high-skilled workers cannot be replaced in the same fashion.

5

1. Introduction

Background

Most work is centred on Anglo-Saxon countries (US, UK).

One fits all? Some say

polarisation is not widespread

polarisation is not likely to be explained by the technical change/routinisation hypothesis (degree of changes, types of jobs, timing).

6

1. Introduction

Aims of the paper

Part of a research contract with Eurofound.

Exploring long-run trends with an uniform methodology.

Informative for the evolution of labour market inequalities Spain, with very bad databases before mid 90s.

Some light on some aspects of the polarisation debate (plausibility of the explanation).

7

1. Introduction

Advancing some preliminary results

Since the late 70s, modernisation of Spanish economy and labour market: de-primarisation, de-industrialisation, rise of the Welfare State, rise of temporary work, housing bubble and financial crisis, labour market crisis.

Overall, the overall pattern is upgrading and polarisation is only relevant in economic crisis.

If polarisation is associated to small segments and periods. Is it really so relevant?

Should we be more cautious about deus ex machina explanations?

8

2. Methodology

The so-called ‘jobs approach’

Define the jobs: combination of an occupation (2-digit ISCO category) and a sector of activity (2-digit NACE).

Ranking (quintiles): rank the jobs according to earnings (or other variable proxying job quality) create quintiles taking a year as reference (this is not innocous).

Monitoring the changes: explore the pattern of changes, how they shape the employment structure and some features behind it.

2. Methodology

Creation of a job matrix

Sector of activity (2 digits)

Act 1 Act 2 … Act N

Occupation (2 digits)

Occ 1 Job 1 Job 2 … Job N

Occ 2 Job N+1 … … Job 2·N

… … … …

Occ K Job (K-1)·N … … Job K·N

Mean/median wage

4. Discussion

The routine-biased technical change hypothesis presents

limitations to explain the behaviour of the Spanish Labour market

other demand-side forces, labour supply issues (migration),

the intensity of the phenomena, etc.

Shortcomings of the methodology (decreasing returns of scale)

The reference period matters.

The entity of phenomena matters.

The number of quantiles matters.

Job quality is much more than pay.
