Austrian economic thinking was characterised by attributing all economic activity, including the behaviour of apparently impersonal institutions, to the wishes and actions of individuals. It did this by examining choices in terms of their opportunity cost (that is, what is the next best use of resources to that which is being considered?) and by analysing the impact of timing on decision making.
The model years 1991 through 2010 were traditional body-on-frame, mid-size SUVs. For the 2011 model year, Ford moved the Explorer to a more modern unibody, full-size crossover SUV/crossover utility vehicle platform, the same Volvo-derived platform the Ford Flex and Ford Taurus use. It is slotted between the traditional body-on-frame, full-size Ford Expedition and the mid-size CUV Ford Edge.
The name was subsequently and briefly used for one of the Ford Explorer Sport (two door)'s trim levels during the 1995 model year, before applied to this SUV for the 1997 model year. Expeditions were originally built in Wayne, Michigan. In 2009, Ford shifted third generation production to Louisville, Kentucky, and converted the Wayne assembly plant to build the Focus. A refreshed third generation arrived to dealers in July 2014 for the 2015 model year.
