1 Exporter Dynamics Database List of Measures and Definitions The firm types used in the database are defined as follows: Exporter t: any firm that exports in year t; Entrant t: a firm that does not export in year t-1 but exports in year t; Exiter t: a firm that exports in year t-1 but does not export in year t; Incumbent t: a firm that exports in both years t-1 and t; nd Year Incumbent t: a firm that exports in years t-1, t, and t+1; 1 st Year Surviving Entrant t: a firm that does not export in year t-1 but exports in both years t and t+1; nd Year Surviving Entrant t: a firm that does not export in year t-1 but exports in years t, t+1 and t+; rd Year Surviving Entrant t: a firm that does not export in year t-1 but exports in years t, t+1, t+ and t+. A graphical illustration of the firm types is provided below where YES indicates that the firm exports in a given year and NO indicators that the firm does not export in a given year: Year t-1 t t+1 t+ t+ Exporter t YES Entrant t NO YES Exiter t YES NO Incumbent t YES YES nd Year Incumbent t YES YES YES 1 st Year Surviving Entrant t NO YES YES nd Year Surviving Entrant t NO YES YES YES rd Year Surviving Entrant t NO YES YES YES YES

HS products exported by a specific Incumbent in t but not in t+1/ N. all HS products exported by the MMS (Product Survival Rate of Incumbents) = (N.
