Abstract:This paper examines empirically how industry-level wage floors are set in French industrylevel wage agreements and how the national minimum wage (NMW) interacts with industrylevel wage bargaining. For this, we use a unique dataset containing about 48,000 occupationspecific wage floors, in more than 340 French industries over the period [2006][2007][2008][2009][2010][2011][2012][2013][2014]. We find that the NMW has a significant impact on the seasonality and on the timing of the wage bargaining process. Inflation, past sectoral wage increases and real NMW increases are the main drivers of wage floor adjustments; elasticities of wage floors with respect to these macro variables are 0.6, 0.3 and 0.25 respectively. Wage floor elasticities to inflation and to the NMW both decrease along the wage floor distribution but are still positive for all levels of wage floors.Keywords: minimum wage, collective bargaining, wages. For that purpose, we collect a large and unique new data set containing all industry-specific scales of wage floors for more than 340 French industries (covering more than 90% of workers of the private sector) over the period 2006-2014. In each industry, wage floors are defined for a specific classification of representative occupations and are used by firms as a reference to set their wages. In our data set, we are able to compute the size of wage floor adjustments between two wage agreements for each occupation. Overall, our data set contains more than 48,000 wage floors for more than 6,000 different occupations defined in industry agreements.Our paper provides new stylized facts on how wage floors are adjusted in France. We first find that the frequency of wage floor adjustments is highly time-and duration-dependent: industrylevel wage agreements are much more frequent during the first quarter of the year, and the usual duration between two wage agreement signing (and so, between two wage floor adjustments) is one year. The frequency of wage floor adjustments is also positively affected by variations of macro variables such as inflation and the growth rate of aggregate wages. Concerning the size of wage floor adjustments, we provide evidence that past inflation plays a key role in 4 explaining the size of wage adjustments. Industry-specific shocks contribute to wage floor increases as long as NMW or inflation increases are not binding.Our second contribution is to investigate the interactions between NMW adjustments and the setting of industry-level wage floors. In France, one important channel of transmission of NMW increases to other wages may come from industry-level wage agreements. To assess the impact of the NMW increases on wage floors, we rely on a Tobit model to disentangle the simultaneous effects of NMW increases on the frequency of wage agreements and on the size of wage floor adjustments. Using changes in the macro variables since the last wage agreement in a given industry, we are able to construct industry-specific variables and to better identify their effects on wage floor...
