چکیده
TABLE A-I LISTS ALL OF THE STATE VARIABLES IN THE MODEL. As some station characteristics are assumed to be fixed and ownership is assumed not to change over time, a state is firm-specific, and the value of the state variables will depend on the characteristics of the stations owned by the firm (some of which are fixed), the characteristics of the firm’s competitors (the set of competitors is fixed), and market characteristics. The table notes (i) whether a variable is fixed over time, (ii) the information assumption made about the variable, and (iii) whether the value is observed or estimated by the researcher in the first stage.

Nber Working Paper Series Dynamic Product Repositioning in Differentiated Product Markets: the Case of Format Switching in the Commercial Radio Industry
The ability of firms to reposition their products can determine the effects of demand shocks, mergers and policy interventions in differentiated product markets. This paper estimates a dynamic oligopoly model to measure repositioning costs in the commercial radio industry. Based on a set of markets where industry revenues were around $88 billion, I find that stations may have spent as much as $...
