“…Ellul, Jotikasthira, and Lundblad (2011) and Merrill et al (2014) To study the effect of insurers' financial constraints on their investment portfolio, we use P&C insurers' operating losses as shocks that worsen their financial constraints. We construct an instrumental variable for the reported P&C insurers' operating losses, following Ge (2019) level from the first step. We then sum the resulting products over all the states for each insurer, and scale by assets at the end of the previous year, to obtain the instrumental variable.…”
