I'm trying to model the economic impact of the 2018 romaine lettuce e.coli outbreak on California counties. During the outbreak, the CDC ordered romaine to be removed from the shelves for a period. I have data on romaine sales by county as well as industry data on romaine shipments by county. My thought is to model this as a change in industry output using decrease in shipments over the period during which the product was not allowed to be sold, but I'm not sure if this is the best event type. Would it be better to use change in commodity output? If so, would it be best to use industry shipment data or consumer sales? Thanks.
