Is there any academic paper documented about firms' trade credit collection approach? I am looking for some papers that documented some trade credit collection approaches, especially when the market becomes more competitive. In another word, what should the managers do to improve the efficiency in collecting the account receivable?
My hit from Google Scholar (had to go to the bottom of page 1 for this one!) is
Macro-Economic Growth,Enterprise Competitive Status and Trade Credit Policy
Abstract:

This paper investigates the effect of macro- economic growth and enterprise competitive status on trade credit policy from suppliers with trade credit's perspective,and the moderate effect of industry characteristics. The study indicates that: The higher the competitive status,the shorter the trade credit collection period to downstream enterprises,while this relation is not obvious among enterprises in less concentrated industry; When macro- economic grows fast,regardless howconcentrated industries that enterprises are located in,enterprises with higher competitive status are more prone to reduce the account receivable collective period; With further considering industry characteristic,the effect of macro- economic growth and competitive status of enterprises on trade credit policy shows significant difference in the quadrant formed by different industry prosperity and concentration.
