In this paper, we explicitly look at the role of inventories as drivers of decision making through an empirical study using firm-level secondary data. Using COMPUSTAT data, we construct a database of supplier-customer pairs and study how downstream inventory decisions affect upstream purchase decisions.
We find support for our hypothesis that manufacturers systematically overreact to downstream inventory changes. Furthermore, we study the origin of said inventory changes through a structural model of the decision-making mechanism and find evidence that firms continuously adapt their safety stocks; the data is consistent with rational decision-makers that vary their cost structure according to the economic and financial conjuncture.
