Location quotient-based travel costs for determining accessibility changes

Journal of Transport Geography, 2021
Abstract Accessibility is not a static feature because it is affected by a large number of factors, such as changes in transport infrastructure, the spatial distribution of human activities, and their interdependence. In this study, we examine the role of location quotient-based travel costs as the travel impedance function in accessibility ...

Dartboard tests for the location quotient [PDF]

Regional Science and Urban Economics, 2009
Abstract In this paper we reinterpret the location quotient, the commonly employed measure of regional industrial agglomeration, as an estimator derived from Ellison and Glaeser [Ellison, G., and Glaeser, E., 1997. Geographic concentration in U.S. manufacturing industries: a dartboard approach.

The location quotient as an estimator of industrial concentration

Regional Science and Urban Economics, 2012
Abstract We construct the location quotient (LQ) from a discrete data generating process and formally test its statistical properties. First, we show that the LQ is typically unbiased, but exhibits finite sample bias when assuming a Poisson distribution. Second, we determine the accuracy of statistical tests, which depends of both sample size as well
