TL;DR: In this article, the influence of ownership on the research and development efficiency of Chinese firms was investigated and it was found that ownership is a contributing factor in the cross-sectional variance of both R&D and productive efficiencies.

TL;DR: In this paper, the authors examined whether switching from a linear to a hub-spoke network confers a strategic advantage because it saves costs and improves service quality, and they found that if hubbing lowers total cost (which includes both airline and passenger inconvenience costs), the pursuit of strategic advantages usually intensifies the extent of hubbing.

TL;DR: In this paper, a large number of routes are served by three or fewer airlines, indicating that a small numbers oligopoly is the dominant market structure in the industry, particularly on the routes directly connected to major hubs.

TL;DR: In this article, the authors investigated the effects of different forms of price regulation on airport efficiency and found that the effect of ROR regulation may lead to over investment in capacity, while price-cap regulation is prone to under-investment.

TL;DR: In this article, the authors investigated the impact of self-internalization on the airport, as this would effectively deprive the airport of an important source of funds for its capacity investment and found that airline market structure has no impact on airport capacity and congestion for a welfare-maximizing airport that receives public subsidy, while somewhat surprisingly, both a private airport and a budget-constrained public airport would tend to over invest in capacity when carriers have market power.
