Snow leopard or mountain lion ?
Thanks,

The industries are defined at a very dis-aggregated level so each firm is not associated with just one industry but with multiple industries and this classification doesn't change over time. For instance: Firm A is associated with 4 different industries and we have three years of data, so there are 12 observations on firm A. My dependent variable, Y, is 0/1 (Did the firm make an announcement in that industry in that year or not). X is a vector of covariates.
