Wage mobility: do institutions make a difference?

This paper checks empirically the assertion that strict labour market regulation leads to low wage mobility, addressing an apparent puzzle. Indeed, most economic reasoning links a combination of regulations in the labour market to low wage flexibility and mobility, but the scarce empirical evidence available challenges that view. I focus on Portugal, one of the most regulated labour markets in Europe. The evidence gathered indicates that an aggregate view-of minimum wage enforcement, unionisation rates and extension of collective bargaining contracts-provides a misleading idea of the actual constraints imposed by the institutional framework on wage setting. Instead, micro conditions at the firm level play a major role shaping wage mobility in Portugal. Some comparisons with the UK, traditionally pointed out as a flexible labour market, are provided. Remarkable similarities in mobility level and trend are detected between the two countries, further suggesting that a regulated institutional framework does not necessarily reduce individual mobility in the wage distribution.
