 abstract = {We present an empirical analysis of product differentiation using a new dynamic panel data set on film programming choice in a major U.S. metropolitan motion-pictures exhibition market.  Using these data, we compute two measures of film programming choice which allow us to investigate the determinants of strategic product differentiation in a multi-characteristics space.  Our evidence is consistent with the idea that the degree of product differentiation between theatre pairs reflects a balance between strategic concerns and contractual constraints.  Similarity in one dimension is offset by differentiation in others.  Finally, we find that ownership matters: theatres under common ownership make more similar programming choices than theatres with different owners.},
