Soler, Alejandro2017-04-272017-04-272017http://udspace.udel.edu/handle/19716/21285The research question this dissertation attempts to answer is whether air freight is significantly associated with population growth; or the income and employment of people in cities; or green geographic spaces. I hypothesize that air cargo throughput is positively associated with these four variables. After appraising the literature on cities, world cities, and world-city networks, as well as establishing the link between airports and cities, I utilize two methods to test my hypotheses. First, I compare two cities – Detroit and Doha – which initially experienced economic and demographic growth before going on opposite developmental trajectories, using the most different systems design [MDSD]. Second, I employ multiple linear regression to test my hypothesis. The results indicate that 1) air freight has a positive association with green area in cities without seaports; 2) air freight is significantly associated with urban employment in cities with seaports; and 3) air freight results in population growth in cities with seaports. ☐ Keywords: Cities, International Relations, capitalist world-economy, uneven development, global commodity chains, air freight, airports, airport citiesThesis984509725
