| Tiivistelmä: | A theoretical framework is presented within which currently prominent structure-performance hypotheses can be analysed. In modeling the differentiated products market power, scale economy, simple collusion, and innovative leading firm hypotheses, particular attention is paid to testable implications derived from formal theories. It is shown that recent evidence of a positive market share - price - cost margin relationship (PCM) and a non-positive concentration - PCM relationship can reject the scale economy and simple collusion hypotheses in homogeneous product markets. This same evidence cannot reject the product differentiation hypothesis in favor of leading firm efficiency. |
