The IMF Working Papers series is designed to make IMF staff research available to a wide audience. Almost 300 Working Papers are released each year, covering a wide range of theoretical and analytical topics, including balance of payments, monetary and fiscal issues, global liquidity, and national and international economic developments.
Widespread shortages in key inputs are common in mixed economies of developing countries. These shortages appear to occur at the same time that relatively high rates of capacity underutilization in manufacturing industries are observed. This paper develops a simple model which explains the existence of excess capacity when there are quantitative restrictions on key inputs. This model is tested using data for manufacturing industries in India, and the results indicate that shortages in domestic rather than imported inputs imposed binding constraints on capacity utilization rates.
