Abstract

This paper presents a new stage-of-fabrication inventory model with ordering usage and stocking of input materials under gross production or value added technology The model extends the traditional linear-quadratic model of output (finished goods) inventories and yields joint decision rules for input and output inventories with extensive dynamic stage-of-fabrication linkages Data show that input inventories are more important than output inventories in business cycle fluctuations Maximum likelihood estimation is relatively successful for a structural inventory model in nondurable and durable good industries The results include evidence of convex costs input-inventory-saving technology and insensitivity to production technology specification
