Throughout the 1930s and early 1940s, U.S. Treasury bonds and notes appeared to have negative nominal yields as they approached maturity. But negative nominal interest rates are impossible in a world in which one can always hold cash. The resolution to this puzzle is that Treasury securities, in addition to making coupon payments, gave the owner the right to buy a new security on a future date. This paper describes the institutional environment that led to the apparent negative nominal interest rates; develops a method for valuing the "exchange privilege"; and computes accurate measures of the yield to the coupon-bearing component of these composite bond/options.

This paper reconsiders the empirical evidence connecting inflation to its higher-order moments. In particular, we examine the statistical properties of the observed positive correlation between the sample mean and the sample cross-sectional skewness of price changes. This correlation has attracted substantial attention over the years and has recently been the focal point of a debate among macroeconomists. We show that the sample mean-skewness correlation suffers from a small-sample bias that accounts for the entirety of the observed correlation. In other words, we establish that one of the stylized facts in the literature on aggregate price behavior need not be a fact at all.
