Tolerance to commuting in urban household location choice: evidence from the Paris metropolitan area

摘要

Many social scientists consider improvements in urban travel facilities during the last decades of the 20th century to have significantly weakened proximity constraints, and therefore think that home-workplace proximity is no longer a major factor in household location choice. They believe that better transport conditions give households more freedom in selecting their homes and workplaces, regardless of the distance separating these two locations. It is argued that this point of view underestimates the costs of daily commuting (which remain an increasing function of trip length), and consequently overestimates households' tolerance to commuting. The author's aim is to measure how much weight households give to home-workplace proximity in actual location choices. With the aid of survey data from the Paris-Ile-de-France metropolitan area, two values are estimated: (i) the share of home and workplace changes (observed between 1991 and 2002) which either bring home and workplace closer to each other or keep these two places close to each other, and (ii) the 'life expectancy' of job-residence combinations which impose long-distance commutes.
