Abstract: Abstract Inventory management literature suggests that product variety may negatively affect inventory turnover. However, little empirical evidence exists to support such a relationship. Inventory turnover is the ratio of sales to inventory, thus, the impact… read more here.

DOI: 10.1080/00207543.2018.1449974
Abstract: We examine the impact of increasing product variety on two measures of a firm’s forecast performance – forecast accuracy and forecast bias – and test whether shared information mitigates this impact. With companies under pressure… read more here.
