Zoom in, zoom out: a shift-share analysis of productivity in Switzerland based on micro data

Using novel data on value added in Switzerland we propose to use a growth rate decomposition technique, in the spirit of shift-share analysis, to analyze the patterns of regional competitiveness over the 2011-2015 period. The growth differential of a region (or canton) depends on four terms, three structural effects and one competitive effect. The competitive effect turns out to be the dominant force at a high level of aggregation. An interesting pattern of structural effects unveils when working at a lower level of aggregation, allowing for identification of the leaders and laggers across regions and sectors.
