Abstract

Abstract: Howard, Newman and Tarp have recently developed a new index of co‐agglomeration, XCL, which improves the existing Ellison‐Glaser index. As this new measure is very sensitive to space fragmentation and fails with MAUP, an improvement based on distances between firms is being proposed here. Original Howard's XCL index is based on individual firm data and was constructed as a probabilistic measure. Data aggregation over territories makes it a cluster‐based measure. Proposed here distance‐weighted improvement, DCL index, is to use its potential to become distance‐based measure, resistant to MAUP and robust to space division.
