This paper investigates the relationships between mutual fund flows and various determinants. High past performance funds and low fee funds enjoy high fund flows, and these finding are consistent with previous literature results. This paper also explores the impacts of search costs on fund flows using fund company size and availability of internet trading platform as proxies. Funds in larger fund companies are positively related to fund flows, because the greater presence of larger fund companies reduces investors’ search costs. Funds in companies that offer internet trading platforms are also positively related to fund flows, because of the higher visibility accompanying the internet trading platform. The control variable, log of lag total net assets, also captures a significant impact.
