The head and tail ends of vegetables from manufacturers to consumers are purely competitive market, farmers and consumers are the biggest victims by the price volatility, however, there are many reasons resulted in high vegetable prices, the research shown in this paper does focus on transaction cost which is one of reasons caused price volatility. Time might be running out to purchase goods at typhoon day, and customers most likely fail to buy food and supplies at hypermarket during this period, or they are impacted by traffic jams etc., transaction cost will be increased due to these factors, hence, retailers may take such opportunity to drive up the price of vegetable, assuming that each consumer has different transaction cost in this paper, not only compare the prices between traditional market and hypermarket, but also research different transaction costs between typhoon day and ordinary day, we are confident to explain the reason caused on volatility of vegetable prices. Under this assumption, we could raise feasible actions to mitigate those issues. Finally, either Government releases vegetable inventory to the market, it could reduce the chance that people fail to buy what they want in the hypermarket during typhoon season, or to improve traffic convenience, we expect it could lower the probability that insufficient vegetable supplied in the market. To conclude our opinion, ensuring stability on the supply of vegetables and reducing the uncertainty that people goes out but fail to purchase what they want are best efficient ways to restrain on raising price of vegetable.
