Inventory Investment Dynamics and Recoveries: A Comparison of Manufacturing and Retail Trade Sectors

This paper explores the existence of a bounce-back effect in inventory investment using the European Commission opinion survey on stocks of finished products in manufacturing and retail trade sectors for France, Germany and a European aggregate, from 1985q1 to 2011q4. Our empirical findings support the existence of a high recovery episode for inventory investment, during the quarters immediately following the recessions: it occurs later and lasts longer in manufacturing than in retail trade sector. Since a third phase of rapid recovery has not been found in final sales data so far, the rebound in inventories could in turn explain the GDP growth bounce-back pointed out in previous empirical studies. This calls for a careful modeling of the inventory investment behavior in any sensible theoretical explanation of aggregate business cycles.
