内容記述 | [Abstract] In the present paper, we investigate the impact of the Covid-19 crisis on the supply of beer in Japan. In Japan, beer industries are mainly controlled by four companies, namely Asahi, Kirin,Suntory,and Sapporo. We grasp this market concentration on a few companies as an "oligopoly," and we further describe the situation as a homogeneous oligopolistic market. In such a market, one of the market leaders will show awareness of the impact of changes in supply and demand on the other members of the oligarchy. We use the concept of "conjectural variation" to describe the effect of such inter-firm awareness. Suppose that the supply level of Asahi is descreased due to the Covid-19 crisis. If this situation occurs, how will it affect another beer company's price of the same product? Conjectural variation refers to Asahi's expectation in regard to the volatility of another beer company's supply levels that will result from Asahi's decrease (or increase) of its own supply level. The present paper holds that, assuming each company determines its supply level to maximize its profit in a homogeneous oligopolistic market, the price level will be determined by three factors: elasticity of price, marginal cost and conjectual variation. Here, we add three further assumptions. First, price elasticity of a certain product is temporarily constant, regardless of the level of total demand. Second, marginal cost in each company is constant, regardless of the production level within its production capacity. Third, conjectural variation in each company is constant in each fiscal term. Based on these three assumptions, price will be determined prior to demand level. Finally, we investigate how change in conjectural variation affects the price level. We find that, if a company's marginal cost is minimized, the increase (or decrease) of the company's conjectural variation will co-occur with an increase (or decrease) of price level, provided that other conditions are equal. | |||||||||
