Nevertheless, tripartite negotiations between the government and social partners typically do not extend to norms for wages increases. In the past years, government intervention in wage setting has been largely limited to determining the statutory minimum wage, which was kept constant from January 2007 until July 2013, when it increased from CZK 8 000/month to CZK 8 500/month, representing 38% of the median wage, one of the lowest ratios among OECD countries. With effect from 1 January 2013, the government abolished the youth minimum wage, which consisted of two differentiated levels, corresponding to 80% and 90% of the statutory minimum wage for those less than 18 and those between 18 and 21 years old, respectively.
