A Buffer Stocks Model for Stabilizing Price in Duopoly-Like Market
Full text linkThis paper presents the staple-food distribution problem in agro-industry. There is a great difference
of staple-food supplies in the harvest-season and in the planting-season meanwhile the demand is relatively
constant. This situation will trigger price-volatility and shortage of staple-food, and it causes opportunity-losses for the stakeholders (producer, consumer, wholesaler/trader, and the government). For stabilizing the
price, the government has several stabilization policies; one of them is market-intervention policy by using
buffer-stocks schemes. The market-intervention policy should be utilized for improving producer’s profit, for
cutting consumer’s expenditure, and for sustaining wholesaler’s margin-profit by implementing price-support
and price-stabilization. In duopoly-like market, we assume that there are only two market-players in the
distribution system. The objective of this research is to determine the instruments for operating Market-Intervention Program which consist of the quantity, time, and price of the buffer-stocks schemes. The problem
was solved using 3 approaches. First, a comparative cost/benefit analysis between free-market and
intervention-market can be used to formulate the objective function of each stakeholders. Second, the
integration of optimization model and econometrics model were use to develop the decision-variables subject
to the expectation of stakeholders, the buffer-stocks requirement, and the dynamics price equilibrium
properties. Third, model market with Inventory was applied for solving the market-price equilibrium. The
result could be used to analyze such the staple-food distribution system, incorporating the configuration of
duo-producers, duo market-buyers, and duo-consumers.
