Pass-through of cost-push pressures to consumer prices
摘要
Costs of intermediate inputs as well as those for product procurement facing Japanese firms have been rising markedly against the backdrop of international commodity price increases and of the depreciation of the yen, as global economy recovers from the COVID-19 pandemic. In this paper, we quantitatively measure the pass-through rate of cost-push pressures on consumer prices and examine the recent changes and their backgrounds in Japan. The estimation results yield the following two implications. First, the exchange rate pass-through rate has been increasing in recent years reflecting higher import penetration. Second, the pass-through rate of raw material and other costs, excluding those attributable to exchange rate, have somewhat increased at the intermediate demand stage and even for some items at the final demand stage. Since the pass-through rates depend on: (i) the strength of cost-push pressures; (ii) the business cycle; and (iii) the tightness of demand and supply condition due partially to the pandemic, their developments should be monitored closely.
