Do the Major League Baseball teams maximize performance or profits?

On the basis of model from paper Barrio and Szymanski (2009) I estimate if the teams are closer to their profit or performance maximizing positions. I found teams in MLB are in short run on average closer to their win maximizing position. Another interesting conclusion is there are almost no differences between clubs in open league system represented by Spanish and English football league and closed league system represented by Major League Baseball in profit maximizing choices. That means the closed league system which is usually used in North America does not help teams to maximize their profits. I examined club characteristics that might explain variations in teams maximizing choices and found that clubs, which are incorporated companies, are on average closer to their profit maximizing choices
