“…Many authors argue that interest rates at di¤erent maturities move together because they are linked by the EH, and a number of studies have addressed the empirical validity of this theory. However, this literature, using a variety of tests and data, generally rejects the EH (e.g., Roll, 1970;Fama, 1984;Fama and Bliss, 1987;Frankel and Froot, 1987;Stambaugh, 1988;Froot, 1989;Campbell and Shiller, 1991;Bekaert, Hodrick, and Marshall, 1997;Bekaert and Hodrick, 2001;Clarida, Sarno, Taylor, and Valente, 2006;and Sarno, Thornton, and Valente, 2007). …”
