A three-stage competition game in an air transport network under asymmetric valuation of flight frequencies
2020
Abstract This paper analyzes the effects of changes in aeronautical charges as brought by several airport management regimes on the air transport industry. Airlines compete on both price and non-prices variables, where connecting passengers have asymmetric valuations of flight frequencies in different legs. Changes in landing fees trigger airlines reactions on flight frequencies and airfares, whose sign depends on the weight attached to flight frequencies. Thus, an increase in the spoke landing fee leads to more international flights under low valuations of frequencies at spoke airports. Simulation exercises show that profit-maximizing aeronautical charges only at the spoke airport are pref…
Credit risk and efficiency in the European banking system: A three-stage analysis
2002
Increased competition and the attempts of European banks to increase their presence in other markets may have affected the efficiency and credit risk in the banking system. The first aspect is the incentive in reducing costs in order to gain in competitiveness. The second is associated with their lack of knowledge of such markets and/ or acceptance of a higher risk in order to increase their market share. Despite the importance of these aspects, banking literature has usually analysed the effects of competition on the efficiency of banking systems without considering these aspects. The few studies that attempt to obtain risk adjusted efficiency measures do not consider that part of the risk…
Global, regional, and national burden of mortality associated with non-optimal ambient temperatures from 2000 to 2019: a three-stage modelling study
2021
Background: Exposure to cold or hot temperatures is associated with premature deaths. We aimed to evaluate the global, regional, and national mortality burden associated with non-optimal ambient temperatures. Methods: In this modelling study, we collected time-series data on mortality and ambient temperatures from 750 locations in 43 countries and five meta-predictors at a grid size of 0·5° × 0·5° across the globe. A three-stage analysis strategy was used. First, the temperature–mortality association was fitted for each location by use of a time-series regression. Second, a multivariate meta-regression model was built between location-specific estimates and meta-predictors. Finally, the gri…
