| Research Abstract |
First, I studied jumps in financial markets. To analyze information inflow and its impact on the markets, I covered events such as the attacks of September 11 2001, the open market operations of the Federal Reserve Board, and the Bank of Japan intervention. Second, I studied an efficient technique for removing "market micro structure noise" induced by sampling high-frequency data. It was well-known that the noise caused covariance estimators to be biased. Therefore, I proposed a statistical hypothesis testing to filter the noise by focusing on an asymptotic property of the maximum eigenvalues of random matrices.
