Home bias and high turnover reconsidered

"The Tesar and Werner (1995) finding of very high turnover rates on foreign equity portfolios is based on an underestimation of cross-border equity positions. Foreign turnover rates calculated using information from comprehensive benchmark surveys on cross-border holdings are much lower than previously reported and comparable to domestic turnover rates. However, the basic intuition from the Tesar-Werner study, that transaction costs do not help explain the observed home bias, is confirmed using data on transaction costs in 41 markets"--Federal Reserve Board web site.
