Abstract
In this study, we set up an empirical model to analyze the causative reasons of the the DRAM price changes by assessing the supply, demand and the average price of DRAM as well as the US GDP and other time-series data from the fourth quarter of 2002 to the first quarter of 2013. The DRAM prices model was established by the sufficiency, industry structure, and overall economic factors and error term adjustments. Empirical results found DRAM prices is mainly influenced by the sufficiency ratio of current period. In addition, results showed that when the overall industrial structure became oligopoly, DRAM prices became stabilized. In the macro factors, the impact of the US economy was weakened after the growing demand of emerging markets. Finally, we found that the influence of DRMA price was resulted from the moving average between actual and expected error in the current and previous period, that is the error can be adjusted about two quarters complete.
