| Summary: | 碩士 === 國立臺北大學 === 統計學系 === 105 === We are experiencing an explosive growth of information. When we hope to obtain some message from the web, we can either enter a keyword(s) search for the required information through search engines. By search engine optimization, banks can use search engine optimization to enable potential customers to search for priority information related to the bank. In this paper, we use Google search engine as an example to explore the heterogeneity in decision-making behaviors for banks using the Google search index (SVI) around the 2007-2008 financial crisis. Investors use the Google search engine to query the status of the bank with the name of banks as a keyword, and the query value is called the Google Search Index (SVI) as a variable of investor attention. Our final study points out that bank with more investor attention have more loans and higher leverage. In addition, after the financial crisis, the performance of these banks gets worse and their probability of default increases more.
