The study aims to measure job destruction (large scale collective redundancies, factory closures…) which can amount to an economic shock from a local perspective, and how it can influence voting in local and national elections. Is there a replacement effect? Is it different for local and national elections? Or according to the sector affected? On the opposite, does job creation conversely affect voting? And if so, is it beneficial for outgoing candidates (vote of confidence) or negative (the wish to bring new blood into office)?
