In his recent paper in this Journal, Miller [3] proposed, following Adler's results [1], that “the investor exhibits decreasing absolute risk aversion with respect to expected wealth if, as increased holding σ constant, the slope of the indifference loci decreases” [3, p. 301]. He further attempted to have shown that in general the sign of () is the same as the sign of r'(W) (the derivative of the absolute risk aversion measure), but this is not proved.

We propose that fund performance can be predicted by its R2, obtained from a regression of its returns on a multifactor benchmark model. Lower R2 indicates greater selectivity, and it significantly predicts better performance. Stock funds sorted into lowest-quintile lagged R2 and highest-quintile lagged alpha produce significant annual alpha of 3.8%. Across funds, R2 is positively associated with fund size and negatively associated with its expenses and manager's tenure.

This paper studies the association between the market's expectations of Saddam Hussein's fall from power, as reflected in “Saddam contract” prices, and stock prices, oil prices and exchange rates. During the war, a rise in the probability of Saddam's fall, which also indicated a speedy end to the war, was positively and significantly associated with stock prices, strengthened the dollar against the Euro, and lowered oil prices. Before the war, a rise in the probability of Saddam's fall, which may also have indicated the probability of a costly war breaking out, lowered stock prices, which adjusted gradually to this information.

We examine theories of IPO underpricing using unique data from Israel where the allocation to subscribers is by equal proration. This enables us to simulate the return earned by uninformed investors. Consistent with Rock's (1986) theory of adverse selection, allocations were negatively related to underpricing. But uninformed investors earned a negative allocation-weighted initial return, although the average initial return was 12%. They could break even, however, by using publicly available information. The data also supports Welch's (1992) theory of information cascades: demand is either extremely high or there is undersubscription, with very few cases in between.

We examine the Cohen and Wang (2013) conclusion that a staggered board lowers firm value based on the stock price reaction to two 2010 Delaware court rulings in the Airgas, Inc. case. The first ruling weakened the potency of a staggered board and the second restored it. We find that the Cohen and Wang results, for their sample, become insignificant after excluding a few penny stocks, stocks with value below $10 million, or over-the-counter (non-exchange) stocks. The effects of the rulings are also insignificant for an alternative sample.

This paper studies the effect of the bid-ask spread on asset pricing. We analyze a model in which investors with different expected holding periods trade assets with different relative spreads. The resulting testable hypothesis is that market-observed expexted return is an increasing and concave function of the spread. We test this hypothesis, and the empirical results are consistent with the predictions of the model.
