Non-aviation revenues and their implications for airport regulation

This paper analyzes a non-congested private airport that possesses market power in providing aeronautical services. We find that the profit-maximizing landing fee decreases in the degree of complementarity of aviation and non-aviation. Furthermore, our model implies that airports will not take advantage of their market power if non-aviation revenues,
or the degree of complementarity of aviation and non-aviation, exceed a critical threshold. In this case, a dual-till regulation will be unnecessary. A single-till regulation, on the other hand, will always result in lower landing fees than laissez-faire.
