The research underlying this paper was done at the Cowles Foundation for Research in Economics at Yale University; and supported by grants from the National Science Foundation and Ford Foundation. We are indebted to Susan J. Lepper and David R. Mayhew for helpful comments, and to Allan Meltzer for generously providing us with their data.

In his original study Kramer found that real income fluctuations affected the incumbent party's vote, but that unemployment and inflation did not. There was a data error in the real income series used in the original article (discovered by George Stigler), however; the revised data indicate that both income and inflation are important electoral determinants. A corrected set of results is reported in Bobbs Merrill reprint (PS-498) of the original Kramer article.
2 Arcelus, and Meltzer, draw their participation data for 1920-1970 from the Statistical Abstract of the United States (1971)Google Scholar. We used a later, revised series for 1930-1972, which is evidently based on new census data or analysis. We have also accounted for the gradual extension of women's suffrage before 1920. See Appendix.

10 The positive correlation is noted by Arcelus and Meltzer (footnote 17, p. 11).

12 Since Var(b – b′) = Var(b) + Var(b′) - 2 Cov(b, b′), for any two estimators b and b′.
13 Using the original Arcelus-Mellzer data (with a corrected C/P series), we reestimated the VP, VD and VR equations. The salient discrepancies between the two sets of estimates are summarized in the table below.
14 Arcelus and Meltzer define the rate as (Pi – Pi-1)/Pi′ rather than the conventional specification (p, – pi-1)/pi-1 .
15 The VD and VR relations involve the same set of regressors. Under these conditions the Zellner procedure reduces to the one used by Arcelus and Meltzer, of separate OLS estimation of each individual equation. Cf. Johnston, , Econometric Methods, p. 240 Google Scholar.

17 In principle the VR – VD, VP system are “seemingly unrelated regressions” to which the Zellner GLS procedure should be applied. The covariance between the disturbances, however, is small; if we let e 2′ e 2′, e 3′ e* be the disturbances in the VR, VD, VP, VR – VD relations respectively, then e 2, = e 1 + e 2, and e* = e 1 – e2. Hence
where Σ1 2 and Σ2 2 are the variances of e 1 and e 2 respectively. Unconstrained OLS estimation of the VR, VD relations indicates σ2 2 and σ2 2 are nearly equal, so Cov(e*,e 3) will be quite small, and the GLS estimates will be very close to our ordinary least squares estimates.

20 The evidence on this presented by Bloom and Price is impressive, though they consider only the income variable. Some very preliminary analysis we have done suggests that the asymmetry they found becomes much smaller if the effect of inflation is controlled for.
