This paper explores changes in prices and supply bottlenecks that emerged during the pandemic using the stock management model, which includes credit adjustment by the private financial sector and central authority. Price determination is designed to respond to discrepancies in the rates of capacity utilization and inventory. If the economy is experiencing supply bottlenecks and the resulting large inflation, it is argued that it is necessary to control the price adjustment sensitivity that may exist in the economy along with efforts to solve supply bottlenecks.
