The theory of resource partitioning proposes that competition among generalists in the center of a market can trigger a process of resource release that engenders a proliferation of specialist producers outside the center. Previous research has generally examined the relationship between this proliferation and market concentration – a correlate of competitive intensity in the center of the market. In this paper, we extend the theory by arguing that resource release also occurs as the degree of competitive overlap among producers in the center intensifies, even when concentration or other structural features do not vary; we expand its implications by demonstrating that increased competitive overlap in the market center should enhance the viability of producers positioned near the center more than those in the periphery; and we enrich and complete it by specifying the additional assumptions needed to extend the theory of resource partitioning to entry processes. Consistent with our expectations, an empirical examination of the Italian broadcast television industry, from 1992 to 2003, finds that the failure rates of both near-center and peripheral organizations decline in response to increasing competitive overlap in the programming of the national broadcasters, with the failure rates of the near-center organizations falling more than those of peripheral organizations. Increasing competitive overlap similarly stimulates the entry of near-center organizations more than peripheral ones.
