| Abstract: | A model of innovation and spatial competition over time is explored. A key implication is that firm's size is positively autocorrelated across time. The mechanism that generates this persistence works only in heterogeneous-product markets and is based on the idea that larger firms possess better information about the design of future products. Private information about the location of product-demand as the sole explanation for why differences in firm size tend to persist over time is emphasized. Several other avenues of persistence - capital fixity,private information on the cost side,and different firm-endowments of an unobserved fixed factor are excluded. |
