Dividend Yields and Stock Returns:A Test For Tax Effects
ABSTRACT
This paper examines the empirical relation between stock returns and
dividend yields. Several equilibrium pricing models incorporating differ
ential taxation of dividends and capital gains are nested as systems of
time series regressions. Estimates of these models and tests of parameter
restrictions implied by the models are conducted within the context of
Zellner's seemingly unrelated regression. It is concluded that the data
fail to support these models as well as the hypothesis that dividends are
neutral. The inability to distinguish between these competing hypotheses
suggests the need for further research before definitive conclusions are
reached regarding the tax impacts of dividends.

DIVIDEND YIELDS AND STOCK RETURNS:
A TEST FOR TAX EFFECTS
By
Patrick J. Hess
Introduction
Th ffect of dividends on stock returns is a major issue in finance, with a
rich historical bacr'und. It has been argued (see Graham and Dodd [19511)
that low yield stocks require iigher returns because investors value dividends
more than retained earnings. Miller and Modigliani [19611 demonstrated that in
a world of no transaction costs, equal tax treatment of dividends and capital
gains, and investor rationality, the dividend policies of firms have no impact on
the welfare of security holders (given investment policies). Miller and Modigliani
pointed out, however, that the heavier taxation of dividends than capital gains
might lead to higher before-tax returns on shares with high dividend yields. But
they wained that such a relation would be weakened and possibly completely
offset by clientele effects. One important class of investors, pension funds, pay
no taxes and, therefore, have no reason to require higher returns on dividend
paying stocks. Other investors, notably corporations and casualty insurance
companies, face lower statutory tax rates on dividends than capital gains. On
the othe1 hand, some investors consuming wealth may find the tax penalties of
dividend paying stocks offset by lower transaction costs if part of their returns
are received as dividends. Recently, even the proposition that dividends are
taxed at higher rates than capital gains has been challenged. Miller and Scholes
[1978] have pointed to features of the tax code and currently available financial
instruments that investors could use to blunt any tax disadvantages of dividends.
Attempts to establish which of these hypothesized relations between
dividends 'and stock returns holds empirically have not resulted in a consensus.

Early tests of the general effects of dividends, such as Friend and Puckett
[1964], relied on cross sectional regressions of common stock prices on
dividends per share, and various alternative measures of earnings or retained
earnings per share. Friend and Puekett found little evidence of yield effects, but
their tests are subject to serious limitations. Black and Scholes (19741 also
tested for the general impact of dividends on common stock returns, using time
series methods that avoided many of the estimation difficulties of the earlier
cross sectional regressions of stock prices on dividends and retained earnings.
On the basis of their test, Black and Scholes [1974] found themselves unable to
reject the hypothesis that dividend yields have no significant effect on stock
returns.
Several authors have tested for the tax effects of dividends by comparing
returns on eum and ex days. Elton and Gruber [1970], in a well known study,
claim documentation of both a tax effect and a dependency between tax rates of
marginal investors and dividend yields (a clientele effect reflected in asset
prices). With a longer sample period and more appropriate statistical procedure,
Black and Scholes [1973] are unable to confirm either of these conclusions.
However, Black and Scholes do find evidence of unusual behavior in security
returns for several days surrounding ex dividend days.
Recent work, notably by Litzenberger and Ramaswamy [1979] and Blume
[19781, has sought to improve the efficiency of the Black—Scholes [1974] tests.
Both papers claims to have found evidence supporting the importance of
dividends. Litzenberger and Ramaswamy, at least, argue that the importance of
dividends is best explained by differential taxation of dividends.
In this paper I present a different estimation method that avoids some of
the shortcomings of the Litzenberger-Ramaswamy and Blume tests. I conclude

Black and Scholes [1974] compare two motels of the relation between
civiciends yields and expected returns:
+ .[E(R) - + (o )/o (1)
E(R) = + .[E(R) (2)
where E(R;) is the expected return of security i, is the covariance of security

return of the market portfolio, is the dividend yield of security i, mthe
dividend ieId of the rnarke portfolio, E(Rm) is the expected return of the
market portfolio, and y,y are parameters of the pricing equation.

Black and Scholes estimate 1' as the average return of the minimum
variance portfolio satisfying the restrictions,
N N N= = 0, = 3)

1 = 1
where N is the number of assets and w is the proportion of asset i in the
portfolio. To reduce the impact of errors in variables, Black and Scholes solve
(4) with twentyfive portfolios constructed from all New York Exchange stocks
that were listed for at least five years. These portfolios are constructed to
maintain dispersion in both beta and dividend yield. The ij elements of the" "2

estimated variance of the equally weighted index of all New York Stock
Exchange common stocks and a is the estimated residual variance of portfolio i

index.
Black and Scholes estimate -y1 as the average monthly return of the
portfolio. For their overall sample period, January, 1939 to December, 1966, the
average return is .09 percent. During three ten year subperiods, the1
estimates range from .02 percent to .16 percent. None of the estimates are
statistically significant.
Litzenberger and Ramaswamy [19791
Litzenberger and Ramaswamy begin by deriving an after—tax capital asset
pricing model of the form,
E(R) - rf = a + b . + c(d1 rf) (4)
where rf is the risk-free rate of interest, d is the dividend yield of security i,

In estimating equation (4), Litzenberger and Ramaswamy consider thestochastic version of their model,
Rt = E(Rt) +
it - rf = a + b it + c(dt - rft) + U. (6)
for securities 1 1,2 ...N and periods t 1, 2 ...T.4 If all thets, dt's, and ri'sin (6) could be estimated without error, the model could be estimated by pooling
cross sectional regressions over time. Litzenberger and Ramaswamy use three
different, although closely related techniques to estimate (6).
The first technique is a regression of individual securities' risk premiums
(returns less than one month T-Bill rate) on a constant, the securities' betas
estimates in the previous sixty months, and a measure of anticipated dividend
yield of the securities for the month less the one month T-Bill rate. Thesecurities' betas are estimated with the followingregression,
R. - r = a. + . (R - r ) + e. (7)ii rt it iT mi ft itfor securities i = 1,2 ...N and T = t—60 ... t-l, where R is the return in month rmT
of a value weighted index of all New York Stock Exchange common stocks. The
measure of anticipated dividends for any month equals the taxable dividends paidin the month if the dividends were announced prior to the beginning of themonth. If the taxable dividends were unannounced and nonrecurring, anticipated
dividends were assigned a value of zero and if dividends were unannounced but
recurring, anticipated dividends were set equal to the last recurring payment.5

The third estimation techni uc seo b Litzenherg€i nad Ramaswamy is
motivated by the errors in variables probien siooiaed with individual secur—
ities beta estimates. The estimation technique icndes an explicit adjustment
foi errors in the beta estimates. Lit.senberger and Ramasamv argue that their
method dealing with errors in cariables is superior to the portfolio rouping
procedure of Black—Scholes because it does not destroy cross sectional dis
persion. Moreover, the authors claim that the estimator is consistent and is a
maximum likelihood estimator if the joint distribution of security returns is
orrnal. These are remarkable claims since the errors in variables problem has
severely limited the ability to rnai<e reliable inferences in financial economics as
weil as onomics in generaL Litzenberger and Ramaswamys adjusted estimator
is analyied in Appendix A and it is shown there that this estimator is neither
consistent nor is it maximum likelihood.
Litzenberger and Ramaswamy derive estimates from each of these tech-
niques b averaging estimates over time. The standard errors of the estimates
itre estimated from the time series of monthly estimates. The resulting
estimates ot c are all quite close. turing the sample period January, 1936 to
Deeember 1977, they are .227, .234 and .236 for the OLS GLS, and adjusted

estimator. The t-values of these estimates relative to zero are 6.33, 8.24, arid
8.62 for the OLS, GLS, and adjusted estimator.6 The adjusted estimator is
computed for six subperiods. Litzenberger and Ramaswamy note that during the
overall sample period of Black and Scholes, January, 1936 to December, 1966,
the dividend yield of the market was .048 per year. Interpreting the Black—
Scholes as equivalent to cdm they infer an estimate of c equal to .225 from
the Black and Scholes estimate of y1 (.0009 x 12/.048). On the basis of this
calculation, they claim to have documented roughly the same effect as Black and
Scholes, but in a more precise way.7
B1urie [1978]
Blume [1978] proposes the following model,
at + b 8it + Ctd1t + (8)
for i = 1, 2 ... N and t = 1, 2 ...T. The coefficients of (8) are each assumed to be
normally, independent1y and identically distributed with means a, b, and c and
variances a , a , anda , respectively. Equation (8) closely resembles the
stochastic version of Litzenberger and Ramaswamy's model, equation (6). The
major differences are supression of the risk-free rate and the interpretation of
random coefficients period by period.
Blume estimates (8) by regressing quarterly returns of twenty-five port-
folios on a constant, the estimated portfolio betas, and a measure of the
portfolios' quarterly dividends yield. Portfolios are used to reduce the errors in
variables associated with estimated betas. Like Black and Scholes, Blume
attempts to maintain dispersion in both the portfolio betas and dividend yields.
The portfolio betas are estimated with sixty months of data prior to the
quarterly estimates. Although monthly data are available, Blume uses quarterly

Alternative Tests of the Tax
Effects of Dividends
In this section 1 will argue that the authors previously discussed have
overlooked important testable properties of models which assume differential
taxation of dividends.
Litzenbe'er and Ramaswamy
Recall that Litzenberger and Ramaswamy's model takes the form,
E(R.t) rf a + b + c(d1t - rf)
where r+ is the riskiess rate of interest in period t and d1t is the dividend yield
![Page 12: dissertation at the University of · market ortfoio, and drn is the dividend yield of the market portfolio. The model (5) is a more general form of Brennans [1970] after tax pricing](https://reader033.fdocuments.in/reader033/viewer/2022042314/5f027b137e708231d4047938/html5/thumbnails/12.jpg)

of security i in period t. The stochastic version of their model is,
R =E(Rt) + u
Rt - rf a + b + c(d. - rft) + (7)
The authors assume that the parameters a, b, and c are constant and they use
five years of data to estimate betas, Implicitly, then, they assume that betas
are constant for five year periods. Combining the assumptions of constant
parameters and betas with the stochastic version of their model results in the
equations,
R -r =1 +yd +yr +u (9)it ft oi lit 2ft it
- = a + b01 1
= C
where (9) holds for all securities and periods consistent with the assumption of
constant betas. The intercept of (9) is free across securities, but constant over
sixty month periods for each security.
The model (9) makes very precise predictions about securities' returns.
First, the model predicts that securities' risk premiums are constant over time,
except for changes in the riskiess rate and the securities' dividend yields. If the
dividend yield of a security, less the riskiess rate, is constant over time, the risk

simplifying,

Equation (10) holds across securities and over time periods consistent with
constant betas. Like (9), equation (10) involves restrictions on parameters for
each security, as well as restrictions on parameters across securities. The
restrictions implied by (10) are more difficult to incorporate than the restric-
tions of (9), because equation (10) includes restrictions on products of para-
meters. More important, estimation of (10) requires identification of the market
portfolio and this imposes an untestable restriction on the data. Nor can much
comfort be taken on the latter count from evidence that suggest particular
implications of asset pricing seem to be insensitive to alternative specifications
of the market portfolio.9 The concern of this study is with a particular problem
and generalization of results obtained with other problems is inappropriate.
Since determining the effects of alternative market portfolios is beyond the
scope of this paper, equation (10) is used only as a check on the sensitivity of
some of our tests.

and one of the terms included in the disturbances depends upon dividend yield,
d:t beeause dividend yields vary over times, Ue variance of the disturbances
and the covariances across securities are not constant. But because. most
quarterly dividend yields are small in absolute value (typically ranging from .0

ignored Lor purposes of estimation. (A more detailed analysis is presented in

Both formulations of Blume's model, (9b) and (lob), closely resemble the
empirical formulations proposed for Litzenberger and Ramaswamy, (9) and (10),
and Brennan, (9a) and (lOa). In particular, the models share the implication that
the dividend yield coefficient is common across securities.
Synthesis of Formulations
Two fundamental equations have been proposed for testing the models of
Litzenberger and Ramaswamy, Brennan, and Blume. The equations are,
= y + y •d. + y .r + c (11)it 01 11 it 2i ft it
R. cx.+cx R ÷a d +it 01 lint 2imt
a.r +d ÷r.(1231 ft 4i it it
Table 1 catalogues the parameter values and restrictions on parameter values
implied by the alternative model.'°
Estimating and Testing the
Alternative Formulations
Equations (11) and (12) are systems of time series regressions with a
regression equation for each security. To estimate the systems properly and to
test the model's implications, the cross sectional dependence in security returns
must be taken into account. Zeilner [1971] has called systems like (ii) and (12)
"seemingly unrelated regressions" (SUR). The regressions have different in-
dependent variables, but are related by the contemporaneous correlation of the
disturbances. The disturbances are presumed to be contemporaneously cor-
related across equations, but the non-contemporaneous covariances and auto-

where k is the number of equations (securities), T is the number of observations,
and 1T is the TxT identity matrix. The Gauss—Markov estimator of the system is,
= [t (E' ® 1) X
The estimator of this system exploits the cross sectional information that
is ignored by single equation estimators. For example, if the independent
variables are orthogonal across equations and if the disturbance are multivariate
normal the SUR estimator say for equation (1) equals,11
s +(x' x - I u . . u )Jl i 1 1 1—i —l 2
Alternatively, if b is the multiple regression coefficient for U. when is the
dependent variable and the remaining k—i disturbances are the independent
variable, the estimator may be expressed as,
6* = 6 + (' x1) x(u - bu -b3u . . .
The estimator adjusts the disturbances for any linear dependence with the
remaining disturbances in the system.
Although the orthogonality condition does not hold for our problem, the
spirit of the adjustment is similar. Thus, if the market portfolio can be
approximated with the securities included in the system, the loss in efficiency
from not including the market portfolio in equation (11) is reduced. More
generally, if security returns are linear in other unobservable factors, the
seemingly unrelated estimator partially adjust for the excluded variables.
If the disturbances of the system are normally, independently, and iden-
tically distributed over time, the SUR estimator is the maximum likelihood
estimator. The feasible estimator involves an estimated covariance matrix

Equation (ha) and (hib) are estimated for a broad cross section of firms.
These firms are classified into systems of securities (equations) on the basis of
average dividend yields. These classifications are meant to control for any
dependency of effective tax brackets on dividends of the kind reported by Elton
and Gruber [1970], and by Litzenberger and Ramaswamy [1980]. If tax
induced clienteles effect asset prices, the tax parameters of (ha) and (lib)
would not be constant across securities, hence, our tests would be more likely to
reject a common effect across securities the larger the dispersion in dividend
yields.
Periods of Analysis and Samples of Firms
The empirical tests are conducted over nine sample periods between
January, 1926 and December, 1978. The sample periods include substantially
different statutory treatment of dividends and capital gains. During the first
sample period--January, 1926 to December, 1931--the statuory limit on dividend
income was 20 percent and the statutory limit on long term capital gains (two
year holding period) was 12.5 percent. Between 1935 and 1940, the statutory
limit on dividends increased from 54 to 75 percent, while the statutory limit on
long term capital gains (one to ten year holding periods) ranged from 30 to 60
percent. By 1945, the statutory limit on dividend income had risen to 90
percent, and 50 percent of the gain on assets held for more than six months were
excluded from taxable income subject to a maximum tax of 25 percent. Between
1945 and 1978, the statutory limit on dividend income decreased to 70 percent,
while the limits on long term capital gains have ranged between 25 and 30
percent.
![Page 25: dissertation at the University of · market ortfoio, and drn is the dividend yield of the market portfolio. The model (5) is a more general form of Brennans [1970] after tax pricing](https://reader033.fdocuments.in/reader033/viewer/2022042314/5f027b137e708231d4047938/html5/thumbnails/25.jpg)

For each of the nine sample periods, systems of thirty securities are
formed on the basis of average dividend yields over the sample periods. None of
the firms included in the systems have nontaxable cash distributions during the
period.
The securities are all sampled from the Center for Research in Security
Prices (CRSP) ionthly return file and include only those firms with complete
data during the period. Each system includes thirty securities.
Data and Defuitioris of Variables
Monthly returns from the CRSP return file are used in estimating the
models. After 1931 the riskless rate of interest is approximated with the one
month Treasury Bill rate. Prior to 1931, the shortest Government Bcnds with a
maturity of at least one month are used to proxy for the riskiess rate. The
source of this data is Ibbotson and Sinquefield [1977].
The dividend yield variable is actual cash dividends paid in the ex dividend
month divided by the closing price in the previous month. Note that this differs
from the definitions of Litzenberger and Ramaswamy and Blume (cf. pages 6 and
8). It is unclear on prior grounds which of the definitions is more meaningfuL
Blume's quarterly measures of dividend yields and returns are not used since our
primary interest is detection of tax effects. With this objective, it is unwise to
destroy time series variation in dividend yields, i.e., the variation due to dividend
yields being zero in months when no dividends are paid.
Estimates and Tests with Equations
(ha) and (hib)
The empirical results for equations (ha) and (lib) are reported in Tables 2
![Page 26: dissertation at the University of · market ortfoio, and drn is the dividend yield of the market portfolio. The model (5) is a more general form of Brennans [1970] after tax pricing](https://reader033.fdocuments.in/reader033/viewer/2022042314/5f027b137e708231d4047938/html5/thumbnails/26.jpg)

through 10. The first column of each table shows the range of average dividend
yield for each system. The second column lists the restricted estimates and
their asymptotic standard errors in parentheses. The third column shows an "F-
statistic" for the hypothesis that yii is equal across securities, and the final
column lists the approximate probability levels conditional on 11i being equal for
all securities in the system. The "F—statistic" reported in these tables are
distributed as F, with degrees of freedom equal to the number of restrictions and
thirty times the degrees of freedom per equation if the covariance matrix is
known.14 For an unknown covariance matrix, the asymptotic distribution is chi-
squared with the same degress of freedom; however, the F approximation is more
conservative with respect to the equality hypothesis.15' 17
The constants in equations (ha) and (hib) implicitly include a beta (times a
market risk premium). Since other authors have assumed stationary beta for
sixty month periods, a dummy variable is included in the estimated equations to
allow for shifts in beta. The dummy variable is assigned a value of zero for the
first half of the sample periods and one otherwise.18
The results of Table 2 thorugh 10 tell a very convincing story. The
restriction that the tax parameter 11i is equal across securities is badly violated
for virtually all the sample periods and yield groups. Since the restriction fails
to hold, it is not clear what, if any, interpretations can safely be drawn from the
restricted estimates. For what it may be worth, the behavior of the restricted
estimates across the dividend yield classification does appear roughly consistent
with the existence of clientele effects. The restricted estimates do appear to be
negatively related to dividend yield, though the relation is not strong or uniform.

models, that 11i+ for Litzenberger and Ramaswamy and Brennan, and
that ye,. 0 for Blume. With equation (11) we thus can separate the hypothesis
that is equal across securities from the other hypotheses.
Equation (11) is estimated with a sample selected from the securities
included in the Dow Jones Industrials during the January, 1926 to December,
1978 period. The sample always consists of thirty securities but the composition
of the sample changes over time. For purposes of comparison, the same thirty
securities used for estimating (11) are also used to estimate (lie) for each of the

nine periods. These results are reported in Table 11. Table 12 reports test
statistics, restricted estimates, and unrestricted estimates for three of the
periods, along with their standard errors.
From the results of Tables 11 and 12, it appears that our earlier
conclusions are insensitive to the specification of the riskless rate. Generally,
the restricted estimates of equations (11) and (ha) are quite close and our
inferences regarding the equality of 11i across equations are unaffected. As for
the riskiess rate, the hypothesis of a common coefficient appears to be a
reasonable approximation for periods after 1960. Prior to 1960, we are generally
able to reject this hypothesis. The unrestricted estimates of Table 13 show a
wide variation in all sample periods but are predominately negative, consistent
with the Fama-Schwert findings. Given the observed variation, it is surprising
that the hypothesis of a common effect of the riskiess rate is not rejected in all
periods. But the smaller variation in the riskiess rate makes precision of these
estimates much lower than that of estimates for the dividend yield coefficient.
An additional check on the sensitivity of the test to model specification
can be obtained from equation (12) which differs from (11) by inclusion of the
market return and dividend yield as separate variables (cf. Table 1). These
estimates are reported in Table 13 for the same time periods and for the sample
of Dow Jones Industrials. Including the market return and yield as separate
variables seems to have little impact on the results. The probability levels,
restricted estimates, and unrestricted estimates are very similar to those of
equation (11).
Definition of Anticipated Dividend Yields
The results presented in Tables 2-13 provide little support for the simple

nx effec. models of dividends. We can reject y model predicting a common
c-.e cie on dividend yield, including the case of neutrality of dividends. it
2ossible that our results are due to the perfect foresight definition of dividend
yields, !iany dividend payments nre announced during the cx month, and
therefor announcement and tax effects may be convoluted in our estimates nf
the dividand i1,d coefficients. There is, of course no reason to suppose that
such announcement eieets would be the same across securities or across time
for the arne securities and because f this our tests may unfairly reject the
hypothesis of a common dividend yield ffec.. To control f or this possibility, we
consider a definition of anticipated dividend ioici tfat relies only upon
information announced prior to the ex month, namely the dnnition oC Litzen—
berger ane Ramaswamy. This choice allows us to make direct cornpaions
their results and may also be regarded as a naive definition from the set ct
possible definitions, i.e., many alternative definitions relying upon information
announced prior to the ex month will have forecasting errors that lie somewhere
between. those of the perfect foresight definition and the Litzenberger and
Ramaswamy definition.

UH .g Litzenberger and Ramaswamy's definition of anticipated dividend
yields, :atiorIs (11) and (12) are estimated with two groups of thirty securities:
the Dow Jones lndusttials sample and a sample of utilities and railroads. The
utility—railroad sample provides a check against peculiarities of the Dow Jones
IndustriaLs, ad this s;:mpie can be presumed to have been identified by investors
as high—yield stocks. The test with these securities are conducted for the same
periods as the previous tests are remrted in Tables 14 and 15. These results
indicate that the earlier conclusions rc;arding th dividend yield coefficient are
basically unaffected by the definition of atcipaed dividend yields. The F-
statistics and restricted estimates change somewhat, but the changes, on
balance, are not large enough to alter our conclusions. Further, the utility-
railroad sample exhibits the same pattern as our earlier samples of high—ield
stocks, and the variation of the unrestricted estimates for the Dow Jones sample
is similar to those earlier under the perfect foresight definition. In sum, the
failure to find a common tax effect cannot plausibly be attributed to an
obscuring of the tax effect by announcement effects impounded in the perfect
foresight definition.
Dividend Yields and Shifts in Expected Returns
Tables 2 through 15 reveal a complex relation between expected returns
and dividend yields. The unrestricted estimates highlight this complexity. In
many reseets, our results are unsettling since we have rejected the two simplest
models of the impact of dividends: neutrality and common tax effects. In fact,
the data 11 us both of these are bad approximations. But not why.
![Page 49: dissertation at the University of · market ortfoio, and drn is the dividend yield of the market portfolio. The model (5) is a more general form of Brennans [1970] after tax pricing](https://reader033.fdocuments.in/reader033/viewer/2022042314/5f027b137e708231d4047938/html5/thumbnails/49.jpg)
One pcssible explanation is that dividend yields are proxying for other
factors that affect returns. Imagine, for example, a world where dividends are
"steady" in the sense of not being adjusted immediately by firms to maintain
constant dividend yields. A decrease in the price of a firm's shares, on average,
will thus imply a higher dividend yield and an increase in price will, on average,
imply a lower dividend yield. For leveraged firms, changes in stock prices may
also result in changes in the riskiness of the firm's stock. Unless firms make
compensating adjustments in leverage, a decrease in the price of common stock
implies a higher leverage ratio and an increase a lower, leverage ratio. As a
result, both dividend yields and expected returns may be increasing or decreasing
simultaneously. Stated differently, equations have been omitted, namely, the
ones determining expected returns, and dividend yields are proxying for the
omitted equations.
To see the possible impact of this relation, consider equation (11). The
intercept of equation (11) may be expressed as,
oit — oi + "itwhereu it is the difference between the expected return of security i in period t
and its average during the sample period (ignoring taxes). Substituting this
expression into eqution (11),
R =y +y d +y r +E v (lic)it oi ii it 2i ft it itThe disturbance term in equation (11) consists of the true disturbance plus the
deviation of the expected return in period t from its average during the sample
period.
Our previous discussion suggests that, on average, it and d1t are both
negatively related to stock prices and, therefore, positively related to each
other. Further, the relation is not easily modeled. The best that we can do is
![Page 50: dissertation at the University of · market ortfoio, and drn is the dividend yield of the market portfolio. The model (5) is a more general form of Brennans [1970] after tax pricing](https://reader033.fdocuments.in/reader033/viewer/2022042314/5f027b137e708231d4047938/html5/thumbnails/50.jpg)
present videnee that establishes the plausibility of the connection. Never-
theless, this evidence had important implications for intercepting tests of the
relation between dividend yields and expected returns (and perhaps also other
anomalies of asset pricing).
To test for this relationsip, we generalize equation (ii) to,
R + v r + y .d y d. + y .d. + (lid)I 01 ii ft 21 it 3i it—i 4a it—2 itwhere dt is the diiiiend yield in month t. The Litzenberger and Ramaswamy
definition of anticipated dividend yields is used in estimating (lid). In effect,
(lid) includes the dividend yield terms of (ii) in both the cum and cx months,
Since the cum month dividend yield is taken from the previous ex month, there
can be no information effects in the coefficient and a fortiori in the two—
month lag coefficient y4. Clearly, there are no tax effects of the kind
hypothesized by Litzenberger and Ramaswamy in these coefficients since the
dividend has already been paid. If the ex month is included, the cum month
effects are purely statistical artifacts from their point of view. The tests
conducted with (lid) are tests of no effect of current or lagged dividend yields.
If both lagged and current dividend yields turn out to be non-zero, there is reason
to believe that dividend yields are proxying for shifts in expected returns. The
results of these tests for the Dow Jones Industrial sample are reported in Table
16.

As can be seen both the lagged and current dividend yields appear to be non-
zero in all time periods. It would be difficult, on the basis of these results, to
conclude either that the current values dominate the lagged value or vice-versa.
The current and lagged values both contribute to the explanation of expected
returns, thus warning again of the perils of attaching too much economic
significance to the observed relations between expected returns and dividend19
yields.

Cone lusions
The purpose of this paper has been to test certain hypotheses on the
relation between dividend yields and expected stock returns, using a methodology
that is more powerful in a number of respects that those that have so far been
used in that context. The method employs systems of time series regressions
with the competing hypotheses taking the form of cross equation restrictions.
The major finding of this paper is that the relation between dividend yields
and stock returns is not constant across securities. In almost all cases examined,
the hypothesis that dividends have a common effect on expected returns can be
decisively rejected. This conclusion is inconsistent with the tax effect models of
Litzenberger and Ramaswamy and Brennan or the similar model of Blume. But
the results are also inconsistent with the hypothesis that dividends have no
effect on expected returns. Stated differently, the tests show a statistically
significant relation between yields and returns, but one that is not well described
either by dividend neutrality or by tax effect models. The unresolved question is
what does explain the results? The observed structure of dividend payments
suggests that dividend yields may be proxying for changes in the expected return
of securities over time. This possibility was tested by including the lagged
dividend yield in cum months along with ex month dividend yield. The cum
month dividend yields have no impact on' investors' tax liabilities and have no
informaitonal content since they are lagged values. Nevertheless, the cum
month dividend yields appear to be as important statistically as the ex month
dividend yields. The cum month results emphasize the need for greater caution
in interpreting the dividend tests here and more generally. They should
especially discourage attempts to appeal to existing empirical tests for justifying

Further, assume that

where M and M are finite positive definite matrices and,

plim = plim (X'x1 plim X'u - plimN-±e N- N N-* N N-° N

since the inverse of is a continuous function which does not
depend on N.
For sake of discussion, possible errors in d1t and rft are
ignored. Equation (A2) may be used to evaluate the effect of errors
in beta on the estimates of c. First, note that for Litzenberger and
Ramaswamy X, V, XX and V'V correspond to,

From equation (A3), it follows that the degree of inconsis-
tency of Litzeiberger and Ramaswaniys estimators will depend only
upon the second column of M'. For C, it will only depend upon the
last element of the second column. To evaluate the effect of c, note
that M equals,

M =111 M2 (6) M1 (6d_rf)
M1 (d-rf) M1 (6d—jrf) M2 (d-Jrf)

M1(d-Irf)is the ith moment of the dividend yields less the risk free
rate around zero and t.1(6d_Jrf) is ith cross moment around zero. The
(3,2) element of the inverse of M is,

first moments of betas and dividend yields. From equation (A2) and
(A3) it follows that,

By assumption, M is positive definite so that M > 0. The

that

It is easy to imagine circumstances where the cross moment around the
mean is not equal to zero. If the cross moment is positive, the
Litzenberger and Ramaswamy estimate will be too large in a probability
limit sense. If dividend yieldsare negatively related to beta, the
probability limit of the estimate will be less than c. While the
magnitude of this effect is unknown for the Litzenberger and
Ramaswamy sample, a serious suspicion is cast on the results
obtained with the '0LS and 'GLS' estimationtechniques.

Recall the Litzenberger andRamaswamy claim that this estimator is both
consistent and the maximum likelihood estimator if the joint distribu-
tion of security returns is normal.
An Examination of Litzenber9er andRamaswamy's Claim of Consistency
It is obvious that the properties of this adjusted estimator
depond upon taking on the value assumed by the authors. If s is
the estimated standard error of , it is necessary that
N v2plimi ___ = 1N-* N i=l s2
for the claims of Litzenberger andRamaswaniy to hold. Suppose that
s' = for all i and each v' is normal with a mean of zero. Each
term in the above sum then would bechi-squared with one degree of
freedom. Further, if each of the estimation errors are independent of
all others, 1/N times the sum will converge to 1 as N goes to infinity.20
Thus, Litzenberger and Ramaswamy's claim that

requires two assumptions: (1) the true standard errors of all the beta
estimates must be known, and (2) each of the estimation errors must be

These are by no means trivialassumptions, although the authors
fail to mention either of them. is simply written down without anydiscussion of the required
assumptions. Neither of these assumptions

has merit. Conceptually, there is no more reason to condition on= Q for all i than there is to assume 6 = . for all i. TheH 1 1
assumption of independent estimation errors, moreover, im1jes the
disturbances of the market modelto independent across securities, which
is inconsistent with I indutry' effects that ha'ie been documented. 21
In summary, the assumptions requi red for Litzenberger and Ramaswamv sadjusted esti mator to be cn i stent are arbi tracy and empi ri callyunattracti ye.
fhe Maximum Ltei ihood Claim
Litsenbergey' and Ramaswamy also claim that their adjustedesimator, maximum likelihood and, indeed, there are conditions wherefliaximrm likelihood estimators exist with errors in variables. Themost irnportt of these conditions is prior know'edge of some of theparameters, If the distriHtjon of the variables are normal, it iswell known that not all the parameters are identifiable. If isknown, the other parameters can be identified and the estimator willbe maximum likelihood if other conditions hold.
In particular, each
row of X must be normally, independently, and identically distributed.
If X is assumed to benonstochastic, then each row of the observed
variable will have a different mean vector (the value of each row ofX). But the X matrix is unobservable and there will be T unknown mean
vectors instead of one. In short, if X is assumed to benonstochastic,
there will be 1-1 more parametersto identify per independent variable.
All this must be accomplished withonly T observation per independent
variable.
In addition, it is required that each row of V and u be
normally, independently, and identically distributed with a mean vector
![Page 64: dissertation at the University of · market ortfoio, and drn is the dividend yield of the market portfolio. The model (5) is a more general form of Brennans [1970] after tax pricing](https://reader033.fdocuments.in/reader033/viewer/2022042314/5f027b137e708231d4047938/html5/thumbnails/64.jpg)

of zero. Finally, each u. and each row of X and V must be mutually
independent.
The assumptions made by Litzenberger and Ramaswamy are not
jointly consistent with these conditions. For purposes of estimating
betas, Litzenberger and Ramaswamy assume that the market model holds,
Rjt - rft = +(Rmt
- rf) + it (A6)
In the stochastic version of their model, equation (7), the distri-
bution is defined as,
=R1t
-E(Rt) (A7)
substituting equation (A6) into (A7),
ut = i mt - E(Rt)] + itIf , Rt and it are all normally distributed, U will be the pro-
duct of two normally distributed random variables, plus a normally
distributed random variable. While sums of normals are normal,
products of normals are not normal. If is normal, then , Rt,and it can not all be normally distributed. If either or it are
not normal, the estimator is not maximum likelihood.However, Rt
simply a linear combination of the Rt and the normality of the
implies the normality of Rmt Clearly, all these conditions can not
be met simultaneously. it follows, then, that Litzenberger and
Ramaswamy's assumptions are not consistent with those required for their
adjustment estimator to be maximum likelihood.
![Page 65: dissertation at the University of · market ortfoio, and drn is the dividend yield of the market portfolio.

62
Besides arbitrarily conditioning on s and the inconsistency of
Litzenberger and Ramaswamysassumptiois with those required for a
maximum likelihood estimator theauthors ignore the fact that betas
and standard errors of betas are functions of parameters in the jointdistribution of security returns. It s rnpiy does not make sense toCall e timsrs of parame cr maximum 1 kel i hoed when a i the para-meters arc being simultaneously estimated. Tks point may heii 'ustrated by noting that

In estimating betas, it is necessary to aJjustE(2.t) for the tax

In summary. Litzenberger and Ramaswamy's claims regarding their
adjusted estimator are wrong. It has been shown that both the con-
sistency and maximum likelihood properties of this estimator depend
upon an arbitrary conditioning argument that the authors fail even to
mention. Further, it was shown that thassumptions made
by Litzenberger and Ramaswamv are not consistent with those required
for their adjusted estimator to be maximum likelihood. Finally,
Litzenberger and Ramaswamy ignore the fact that the betas and standard
errors of beta are parameters in the joint distribution of security
returns. In short, there is no reason to believe that their adjusted
estimator is any better than the OLS and GLS estimators they report.

From (B2) it is clear that the disturbances of (Bi) are not homosced-
astic. Define the part of the variance of the disturbances that is
constant as,
E ? + 2 + 2 a2
Equation (B2) may be written as,
E = + dt G
= ? (1 + x. dt) (B3)
where = The changes in the variance of u over time depends
upon d. Since is the ratio of one variance to three variances,
it is probably reasonable to approximate A1 with a value of about .33.
An average quarterly dividend yield is approximately .01; for a high
yielding stock the value would be .02. Thus, in an ex month the
variance of the disturbance would be about ? (1.000033) for an average
firm, and (1.000132) for a high yielding firm. In a non ex month,

FOOTNOTES
1. It is possible that a relation more complicated than the ones tested herecould exist. See, for example, Constantinides, G. [1979].
2. Actually c is a weighted average of investors' marginal tax rates where theweights equal the global risk tolerance divided by the sum of the global risktolerances across all investors, see Litzenberger, R., and Ramaswamy, K.,[1979, 171i't2].
3. lbid.,p.2.
4. Ibid., p. 15.
5. Only dividends paid in the last twelve months are used to calculate theunannounced but recurring dividends. See Litzenberger, R., and Rama-swamy, K., [1979, 182].
6. Litzenberger, R., and Ramaswamy, K., [1979, Table 1].
7. The reliability of this calculation is questionable. First, Black and Scholesmeasure dividend yield for any year as dividends paid in the previous year,divided by the closing price of the previous year. Tax liabilities will dependupon dividends actually paid and not the previous years dividends. Apossible differential tax liability will not be proportional to the Black andScholes measure of dividend yield. Second, Black and Scholes estimateusing both ex and non-ex months. Since tax effects only occur in ex months,the estimates mixes tax effects with other dividend related effects.Finally, Black and Scholes use an equally weighted index and not a valueindex. In short, the relation between estimate and the presumed dividendtax bracket of the marginal investor is by no means clear. The most thatcan be said is that a positive estimate in a Black and Scholes test isconsistent with differential taxation of dividends.
8. Blume apparently expected a negative coefficient, a preference by investorsfor dividends, see Blume, M., [1978, 1].
9. See, for example, Stambaugh, R., [1979].
10. Gordon, R. and Bradford, D. (1979) estimate a model similar to (12).Unfortunately, the authors never test any of the restrictions implied bytheir model.

16. Recently, attention has focused on the finite sampling properties of this teststatistic. Meisner has reported simulations that would sugge't the teststatistic is heavily weighted toward rejecting the restriction when thedegrees of freedom are small per equation. As expected, as the degrees offreedom grows per equation (23 per equation were exsmined by Meisner) thebias is substantially reduced. Since the degrees of freedom are quite largehere, the large sample aproximation will be assumed to be appropriate. SeeMeisner, J., [1979] and Laitinen, K., [1978].
17. The F—distribution is more onservative with respect to rejecting therestriction and that approximation is adopted here. See Theil. H., [1971,402-O3}.
18. Since none of our hypotheses involve dummy coefficients, these estimatesare not recorded.
19. This sample was also used to test for common cum month effects andcommon differences between cum and ex month effects. In general, theserestrictions were rejected at high probability levels.
20. This sum is distributed as chi-squared with N degrees of freedom. 1/N timesthe sum has a mean of 1 anda variance of 2/N. See Theil, H., [1971, 402].
