In the popular press and among policymakers the effect of no-fault divorce laws on divorce rates remains an issue (see e.g., New York Times, 23 July 1991). In my 1986 article in this Review, I show that the adoption of one form of no-fault divorceunilateral divorce-does not lead to a significant increase in divorce rates.' The theoretical model that is consistent with this empirical evidence would imply that the new law does not decrease the costs of divorce. It merely redefines which party has the right to terminate the marriage.

This paper measures the extent to which farmers are able to use savings and dissavings to smooth consumption in response to unexpected shocks to income. Time-series information on regional rainfall is used to construct estimates of transitory income due to rainfall shocks. The relationship between these measures of transitory income and savings indicates that farm households save a significantly higher fraction of transitory income than nontransitory income.

This analysis was concerned more with the sign and significance level of each subsample estimated CONC coefficient.

Weekly data for foreign currency futures prices are examined for evidence of risk premiums. Covariance risks are measured with respect to the excess returns from benchmark portfolios for consumption and wealth. When the parameters representing the prices of the covariance risks are held constant, no risk premiums are detected. However, when these prices are allowed to vary with the conditional expected returns and variances of the benchmark portfolios, possibly reflecting changing investment opportunities, strong evidence of risk premiums is obtained.

The outstanding face amount of plain vanilla interest rate swaps exceeds two trillion dollars. While pricing and hedging of such swaps appear to be quite simple, many existing theories are based on the incorrect characterization of a swap as a simple exchange of a fixed for a floating rate note. This characterization is not consistent with standarized swap contracts and the treatment of swaps in bankruptcy. This paper provides an alternative perspective on swaps.

This study investigates the extent to which information inferred by investors from initial announcements of corporate security offerings affects share prices in the capital markets. The empirical tests measure the response in the common stock prices of both firms announcing a security offering and nonannouncing firms operating in the same industry. Small but significantly negative abnormal returns are shown by industry shares upon initial announcements of common stock, convertible debt, and straight public offerings. Such an industry response indicates that share prices incorporate an inside assessment of factors relevant to the valuation of an industry subset of firms.
