Convergence and clustering in major league baseball: the haves and have nots?

There appear to be two distinct views on the level of competitive balance within Major League Baseball. One view, mostly associated with academics, is that competition is more equal today than it ever has been. The other view, mostly associated with the media and the industry, is that competition is far worse today. The present paper, borrowing from the literature on economic convergence, finds that both views are valid. More specifically, while competitive balance has continued to improve, the improvement has been such as to create distinct convergence clusters. A discussion of the composition of these clusters is offered in the text.
