ABSTRACT
Accessibility is a fundamental concept in
theories of metropolitan spatial structure. Urban economic models explain urban structure
as a function of access to jobs; accessibility is capitalized into land values, which in turn
explain the population distribution. Studies of residential land values show that
many factors contribute to the value of a given`location: the characteristics of the housing
unit, its location with respect to social and environmental amenities, as well as access to
jobs, services and other economic opportunities.
Empirical studies typically use job access as a
proxy for more generalized access to economic activities. However, jobs represent
many different activities, from retail shopping to heavy manufacturing, and the value of access
to these activities may be positive or negative. In this paper, accessibility measures based on industry
sectors have been developed,
allowing the separating out of possible different effects.
