Does collective bargaining influence the way the size of the firm impacts wage dispersion? Spanish evidence

PurposeThis paper analyses the relationship between wage dispersion and firm size within a “two-tier” system of collective bargaining (firm bargaining and multi-employer bargaining levels). Collective bargaining has a decisive role in setting wages in Spain, and its regulation highly limits the possibility for smaller firms to negotiate their own collective agreement.Design/methodology/approachBased on the Spanish Structure of Earnings Survey 2006, 2010 and 2014, the authors use variance decomposition in order to deeply analyse the effect of bargaining level on wage dispersion and compare the value of each decile of the distribution of wages for the purposes of identifying the quantitative differences in wage compression.FindingsIn general, the outcomes positively linked firm size and firm bargaining to wage dispersion. However, if firm size is taken into account, the effect of firm bargaining is limited among small firm workers because this type of firm is not usually covered by firm bargaining. On the other hand, the time analysis allows observing a wage compression that follows different patterns depending on firm size, compressing the higher part of the distribution in case of small firms and the lower part in case of large firms. This should be explained by the fact that wage negotiation is dependent on firm size.Social implicationsFirm size has determined firm adjustment strategies to face the recent economic crisis and allows to evaluate the impact that changes in collective bargaining can have on wage distributionOriginality/valueThere is no research that has tried to analyse the relationship between wage dispersion and firm size in a context where collective bargaining is essential to understand the wage structure. Normally, firm size plays a decisive role in wage policy given that the capacity of a company to negotiate an agreement is closely linked to its size.

Wage Compression within the Firm: Evidence from an Indexation Scheme

We revisit the role of labour market institutions by showing how they affect the sharing of firm-specific rents between employers and employees. We look at an Italian wage indexation mechanism (‘Scala Mobile’) that compressed the distribution of wages, imposing real wage increases at the bottom of the distribution. After developing a simplified version of a search model with intra-firm bargaining and on-the-job search, we document that skilled workers received lower wage adjustments when employed at firms with many unskilled workers and they tended to move towards more skill-intensive firms. Moreover, the system drove the least skill-intensive firms out of the market.

The minimum wage as a wage equality policy: Evidence from North Macedonia

The paper aims to investigate if the minimum wage increase of September 2017 resulted in better wage equality in North Macedonia. The increase of 19% was sizable and included levelling up in the three sectors with a lower minimum wage: textiles, apparel, and leather. We extend the ?cell? approach of Card (1992a) and rely on data from the Labour Force Survey 2017 and 2018. The results suggest that the 2017 increase in the minimum wage had a positive, significant, and robust effect on wages. However, the wage increases were almost entirely positioned on the left side of the wage distribution and implied wage compression up to or around the minimum wage. The bunching around the new minimum wage level ?equalised? workers: those who previously earned the new minimum wage level equalised with the less productive workers who approximated their wage only by the power of the law. Hence, wage equality improved. The results confirm that the minimum wage can be an important wage equality policy, with considerably limited upward spillover effects in the current policy and institutional setup.

Collective bargaining, wage dispersion and the economic cycle: Spanish evidence

This research analyses the effect of a ‘two-tier’ system of collective bargaining (firm bargaining and multi-employer bargaining levels) on wage dispersion in Spain. The effect of collective bargaining on the two main concepts that make up wages (the contractual or basic-bargained wage, and the wage cushion) are analysed during the last period of the upward cycle (2002–2006) and the beginning of the global financial crisis (2006–2010). The wage cushion is defined as the difference between the earned wage and the basic-bargained wage. The results show that workers covered by firm bargaining experienced greater wage dispersion than workers covered by multi-employer bargaining. On the other hand, wage dispersion for all workers decreased during the analysis period, mainly during the first stage of the current economic crisis, and particularly among workers covered by multi-employer bargaining. Both the decreasing relevance of the wage cushion in actual wage formation and its reduced dispersion make it possible to explain this wage compression.
