The demand for casino gaming with special reference to a smoking ban.
Thalheimer, Richard ; Ali, Mukhtar M.
I. INTRODUCTION
There is a sparse literature on the determinants of the demand for
casino-style gaming. This study adds to that literature. A major focus
of this analysis is on the effect on gaming demand of the introduction
of a smoking ban into an existing gaming market, in this case the State
of Delaware. A comprehensive statewide ban on smoking in public places
was implemented in Delaware on November 27, 2002. The ban was titled the
"Delaware Clean Indoor Air Act" (the Act). Gaming facilities
open to the public were one of the locations specifically cited by the
Act as subject to the ban.
The subjects of this analysis are the three Delaware racinos over
the period September 1996 through December 2004. A racino is a
pari-mutuel racetrack that has the statutory authority to offer
electronic gaming devices (slot machines) to its customers. In 1990,
there was only one racino in the United States, Mountaineer Park in West
Virginia. By 2005, there were 13 states that permitted slot machine
wagering at pari-mutuel racetracks. (1)
In some states, the electronic gaming devices at a racino are
operated by the entity that owns the racetrack. In other states, the
devices are operated under the auspices of the state lottery with the
racetrack acting as a lottery agent. In such cases, the electronic
gaming devices or slot machines are alternatively referred to as video
lottery terminals (VLTs). Such is the case in the State of Delaware. (2)
To show the importance of VLT gaming in Delaware, consider that in
fiscal 2004 total state lottery revenue was $641 million. Video lottery
revenue was $532 million or 83% of total state lottery revenue. The
remaining 17% of total lottery revenue came from traditional on-line and
instant lottery games (Delaware Lottery, 2004).
A system of three demand equations was developed to examine the
effect of a set of determinants on slot machine wagering (handle) at the
three Delaware racinos. The system is described by the seemingly
unrelated regressions (SUR) model and was jointly estimated with the
well-known seemingly unrelated regression estimation technique. VLT
handle was found to be positively related to the number of VLTs, per
capita personal income, and population. VLT handle at a racino was found
to be negatively related to the number of VLTs at the other Delaware
racinos. This negative relationship of the number of VLTs at other
racinos to a particular racino's wagering demand indicates that
they are substitutes. Gaming demand was found to decrease with the
implementation of the Delaware statewide smoking ban.
The study proceeds as follows. Section II is a review of the
literature on the demand for casino wagering. Also included is a review
of the literature on the effect of a smoking ban on revenues of gaming
and non-gaming establishments. Section III develops a three-equation
system demand model, one equation each for the three Delaware racinos.
Section IV reports the estimated models and presents empirical results
on the factors affecting the demand for casino wagering. Section V
summarizes the findings and draws further conclusions.
II. PREVIOUS STUDIES
Only two studies have examined the determinants of the demand for
casino gaming. Thalheimer (1998) investigated the determinants of the
demand for slot machine wagering at the first racino in the United
States, Mountaineer Park, a thoroughbred racetrack in West Virginia.
During the study period, 1990-1991, Mountaineer Park was permitted to
offer a limited number of electronic gaming devices to its customers
under the auspices of the state lottery on an experimental basis. VLT
wagering demand was found to be positively related to the number of
VLTs. The price of VLT wagering did not vary over the study period, and
hence, its relationship to the demand for wagering could not be
ascertained. Thalheimer and Ali (2003) investigated the determinants of
slot machine wagering at 24 riverboat casinos and three racinos in the
Midwestern states of Illinois, Iowa, and Missouri. The study period was
from 1991 through 1998. Slot machine handle at a riverboat or racino was
found to be positively related to the number of slot machines at the
facility. Handle was found to be negatively related to the price of
wagering at the facility and to the availability of competing gaming
facilities.
Unlike the limited number of studies on the demand for casino
wagering, there have been a number of studies that have examined the
determinants of casino wagering revenue. Casino wagering revenue is
total handle less the amount paid back as winnings to customers. Revenue
is also referred to as win since it is the amount "won" by the
casino after payback of winnings to the customer. Revenue and wagering
(handle) are intimately related. As the price of casino wagering is win
percent, defined as revenue from wagering (win) divided by total
wagering, revenue is the product of wagering and the price of wagering.
Prior studies of the determinants of casino revenue include those of
Cargill and Eadington (1978), Nichols (1998a, 1998b), Hunsaker (2001),
Levitzky, Assane, and Robinson (2000), Mandel, Alamar, and Glantz
(2005a, 2005b), and Pakko (2005, 2006).
The studies of gaming revenue by Mandel, Alamar, and Glantz (2005a,
2005b) and Pakko (2005, 2006) included a smoking ban variable as a
revenue determinant. In addition to the smoking ban variable, Mandel,
Alamar, and Glantz (2005a) included the following gaming revenue
determinants: quadratic trend, number of VLTs, income, and a seasonal
dummy variable for winter. The introduction of the Delaware smoking ban
was found to have had a positive but insignificant impact on aggregate
Delaware VLT revenue and revenue per machine. In an erratum to this
study, Mandel, Alamar, and Glantz (2005b) acknowledged that it contained
a data error and subsequently found evidence of heteroskedasticity in
the equation for total revenue. Correcting for the data error and
adjusting for heteroskedasticity, they found that the introduction of
the smoking ban had a negative but insignificant impact on total
revenue.
Pakko (2006) reestimated the aggregate VLT revenue model used in
Mandel, Alamar, and Glantz (2005a, 2005b) making adjustments to
methodology and found the effect of the smoking ban to be negative and
significant. In another article, Pakko (2005b) estimated a revenue model
for each of the three Delaware racinos with a modified version of the
model used in Mandel, Alamar, and Glantz (2005a, 2005b). In addition to
the smoking ban variable, gaming revenue determinants included the
following: quadratic trend, number of VLTs, index of economic activity,
monthly dummy variables, and a dummy variable for a month in which a
snowstorm occurred. The estimated impacts of the Delaware smoking ban on
VLT revenue at each of the three Delaware racinos were found to be
negative and significant.
There is an inherent difficulty in evaluating the results of the
prior studies that have examined the impact of a smoking ban on casino
revenue rather than on casino handle. The main reason for this is that
revenue is affected through two sources: wagering and the price of
wagering. Thus, factors, including the smoking ban, that affect wagering
and those that affect the price of wagering must be the factors that
affect revenue. To assess the impact of a smoking ban on revenue, one
must include all these factors, both those that affect wagering and
those that affect the price of wagering, in the revenue equation. In
addition, racino revenue may also be affected by competition from other
nearby gaming opportunities such as, in this case, casinos in Atlantic
City, New Jersey, a racino in Charles Town, West Virginia, state
lotteries in Delaware and surrounding states, and competing parimutuel
facilities. Exclusion of any one of these relevant factors in the
previous casino revenue models that included a smoking ban as a revenue
determinant may result in a biased estimate of the smoking ban's
effect on revenue.
While the effect of a smoking ban on the demand for casino gaming
is the focus of this study, there are a number of past studies that
examined the impact of a smoking ban on the revenues of restaurants and
bars. Notable among these are Dunham and Marlow (2000a, 2003). Dunham
and Marlow (2000a) examined the effects of smoking laws on revenues
using a 1996 national survey of 1,300 restaurants and bars. Respondent owners were asked if revenue would be affected by the implementation of
a virtual smoking ban. Six percent of restaurant owners expected revenue
to rise, 39% expected revenues to fall, 51% expected no change, and 4%
did not know. For bar owners, 2% expected revenues to rise, 83% expected
revenues to fall, 13% expected no change, and 2% did not know. While a
slight majority of restaurant owners expected no change, an overwhelming
majority of bar owners expected a negative effect from a virtual smoking
ban. The differential effects on revenue of an assumed virtual smoking
ban are observed not only on the type of business, in this case
restaurants or bars, but also between businesses, for example,
restaurants and bars.
Following Dunham and Marlow (2000a), Dunham and Marlow (2003)
analyzed the effect of a smoking ban on profits using a survey of
restaurant and bar owners in Wisconsin in 2001. The study results
confirmed the findings of Dunham and Marlow (2000a) that the effects of
a smoking ban vary widely across establishments. Their analysis also
suggests that restaurants that cater relatively more to smoking
customers are expected to experience a greater loss when faced with a
smoking ban.
In addition to the survey-based studies of the effects of a smoking
ban on establishment revenues and profits, Dunham and Marlow (2000b,
2004) examined the effects of a smoking ban on nonsmoking seating
allocations of restaurants and bars. Dunham and Marlow (2000b)
reanalyzed the data used in Dunham and Marlow (2000a), while Dunham and
Marlow (2004) reanalyzed the data used in Dunham and Marlow (2003). An
important finding of these studies is that the firm's choice of the
mix of smoking/nonsmoking seating is intimately related to the smoking
preferences of customers, and this choice of seating allocation is
consistent with the profit-maximizing behavior of a firm. As expected,
given the smoking preference of the customer, converting seating for
smoking use to nonsmoking use rewards nonsmokers, resulting in a gain in
profits, while it penalizes smokers, resulting in a loss in profit.
A profit-maximizing firm chooses the allocation of seating, where
at the margin the gain in profits matches the loss in profits. Thus, the
optimal share of nonsmoking seating should be inversely related to the
percentage of customers who smoke. Any deviation from this optimum
allocation will result in a loss in profit for the firm. As the policy
of a complete smoking ban reallocates all the smoking seats to
nonsmoking use, it is expected that such a policy will result in a loss
to a firm that is operating with the optimum or near-optimum allocation
of seats as long as there are customers in the population who smoke.
Furthermore, the loss in profit will be positively related to the
percentage of customers who smoke. However, if the firm is operating
with no seats allocated to nonsmoking use, it is not clear whether a
comprehensive smoking ban policy will result in a gain or loss in profit
to the firm. This is because both the allocation of (i) no seats to
nonsmoking use and (ii) all seats to nonsmoking use are suboptimal,
resulting in a reduction in profit from that which would result with
optimal allocation. The magnitudes of these reductions cannot be
predicted without knowledge of the extent of the suboptimality of these
two allocations. However, as the optimal share of nonsmoking seats
decreases with an increase in percentage of customers who smoke, it is
expected that there will be a loss in profit with the policy of a
comprehensive smoking ban if the percentage of customers who smoke is
large.
The above analysis suggests that the policy of a comprehensive
smoking ban will have differential effects on firms depending on each
firm's pre-ban share of nonsmoking seats and the percentage of its
customers who smoke. Furthermore, the loss in profit will be positively
related to the percentage of customers who smoke. This observation is
consistent with the findings of Dunham and Marlow (2000a, 2003), where
it was found that revenue or profit loss is more likely among bar owners
than among restaurant owners. It may also be concluded that revenue or
profit loss will decrease as the percentage of smokers in the population
decreases. For our study, each of the three establishments (racinos)
sell the same product, that is, slot machine wagering, and are located
in a relatively similar environment with regard to the percentage of
smokers in the market area populations. To the extent that all three
establishments did not allocate any seats for nonsmoking use before the
policy of complete smoking ban was introduced, the policy of a
comprehensive smoking ban is expected to affect the profitability of
these establishments similarly. Unfortunately, the direction (positive
or negative) of these effects cannot be predicted.
While Dunham and Marlow (2000a, 2000b, 2003, 2004) analyzed the
impact of a smoking ban on individual establishments, a number of
studies aggregated all restaurant, bar, and/or hotel business
establishments into one "community-wide" impact. Almost all
these studies (Glantz and Charlesworth, 1999; Glantz and Smith, 1994,
1997; Goldstein and Sobel, 1998; Huang et al., 2004; Hyland, Cummings,
and Nauenberg, 1999; Sciacca and Ratliff, 1998), which used historical
taxable sales, concluded that businesses, as an aggregate, do not suffer
reduced sales as the result of a smoking ban. In light of the findings
by Dunham and Marlow (2000a, 2003) of differential effects (both
positive and negative) of a smoking ban on individual establishments,
the finding of an insignificant aggregate effect is not a surprise.
However, as our study deals with three individual establishments each
selling the same product, that is, slot machine wagering, findings from
these earlier studies are not relevant to evaluating the effect of a
comprehensive smoking ban on these establishments.
III. DETERMINANTS OF THE DEMAND FOR VLT WAGERING
In this study, the demand for VLT wagering at each of the three
Delaware racinos is determined. Demand determinants include the price
and product characteristics of the subject facility, the price and
product characteristics of competing product facilities, market area per
capita income, population, and other external market environment
conditions.
In addition to expanding the literature on the effects of
traditional demand variables on wagering demand, a major focus of this
study is on the effect of a smoking ban on slot machine wagering demand.
While prior studies of the effects of a smoking ban on casino gaming
addressed the relationship of a smoking ban to racino revenue, this
study addresses the impact of a smoking ban on casino wagering demand
(handle).
The study period for this analysis was chosen as the 100-month
period from September 1996 through December 2004. The study period was
chosen such that it began 1 mo following the start-up of the last racino
to come on-line in Delaware, Harrington Raceway. As a result, there were
an equal number of observations for each racino in the data set. The
study period includes 25 mo following the introduction of the Delaware
statewide smoking ban.
The demand variable is defined as total VLT wagering (handle). The
price of VLT wagering is long-run average win, the amount retained by
the racino after payback of winnings to customers, as a percent of total
wagers (handle). The realized win percent for a month provides an
estimate of this long-run win percent. Although there were small
variations in the estimated win percent over the sample period, these
were largely random variations and not likely to be associated with
racino operator decisions to change the price. Thus, win percent was not
included in the demand equations. Since an increase in the number of
VLTs is expected to increase access to the gaming product and thus
reduce the associated cost of waiting for an opportunity to play, the
number of VLTs serves as a measure of some aspect of price (reward) of
wagering. We have included this variable in the demand equations. Of
course, the demand for VLT wagering is expected to be positively related
to the number of VLTs.
Each of the three Delaware racinos faced competition from the other
two Delaware racinos over the sample period. The demand for wagering at
any one of the three Delaware racinos is expected to be affected by
product characteristics of the other two measured, in this case, by the
number of VLTs at the competing racinos. To the extent that the Delaware
racinos are substitutes for one another, the demand for wagering at any
one racino is expected to be negatively related to the number of VLTs at
the other Delaware racinos. Only those substitute racino products that
were found to be significant were included in the demand equations.
The Delaware racinos faced external market competition from casinos
in Atlantic City, New Jersey, and a racino in Charles Town, West
Virginia, over the study period. The win percent at each of these
locations was unchanged over the study period. Thus, win percent at
these locations was not included in the demand equations. The number of
slot machines at each of these locations over the study period was not
found to have a significant effect on handle at the Delaware racinos,
and so these competition variables were dropped from the demand
equations as well. (3)
The Delaware racinos faced pari-mutuel wagering competition from
racetracks and/ or off-track betting facilities in the states of
Maryland, New Jersey, New York, Pennsylvania, Virginia, and West
Virginia. Pari-mutuel wagering, either simulcast or live and simulcast,
was held at these facilities year-round. There was no change in takeout rate for the live races over the study period. (4) For this reason, the
effect of pari-mutuel competition on Delaware racino handle could not be
determined. In a prior study, Thalheimer and Ali (2003) found that
competition from parimutuel wagering facilities did not have a
significant effect on casino wagering.
Finally, even though the Delaware racinos were under the auspices
of the Delaware state lottery, the Delaware racinos faced competition
from traditional (non-VLT) Delaware lottery games. The Delaware racinos
also faced competition from neighboring-state lotteries in Maryland, New
Jersey, and Pennsylvania. The weighted average lottery takeout rate
(100% less the percent of sales paid out in prizes), using total lottery
sales in each state as the weighting factor, was computed for the
Delaware state lottery and the three surrounding state lotteries. (5)
The lottery takeout rate was not found to have a significant effect on
handle at the Delaware racinos, and so this competition variable was
dropped from the demand equations.
For the reasons given above, the external market competitors were
not included in the demand equations.
VLT wagering demand for each racino is expected to be positively
related to its market area per capita personal income and population.
Following Thalheimer and Ali (2003), market area population for each of
the three racinos was defined as the population in those counties that
were located within a 100-mile radius of the racino. Following the
analysis in Section II of this report, neither the direction nor the
magnitude of the effect of the change in the external environment caused
by government restrictions on smoking in public places, that is, the
Delaware smoking ban, can be predicted. However, it is expected that the
effect of a smoking ban will not vary across the three racinos. A dummy
variable to represent this change in environment was included in the
equations. In addition to the aforementioned variables, 11 monthly
seasonal dummy variables were also included to capture seasonal
variations, if any, in wagering.
Equations (1)-(3) show the specification of the demand for VLT
wagering at each of the three Delaware racinos.

variables; VLTS_DEL, VLTS_DOV, are VLTS HAR are the number of VLTs at

the three racinos; POP_DEL, POP_DOV, and POP_HAR are market area

over which the Delaware smoking ban was in place; and u is the overall
error term. More detailed variable definitions, construction, and data
sources are given in the Appendix. Summary statistics are given in Table
1.
In specifying the functional form of the slot machine handle
equations, note that handle is by definition positive. A simplistic functional form that guarantees this positive condition is one that
relates the logarithm of handle to its determinants. Following
Thalheimer and Ali (2003), this functional form was chosen for the
analysis. It is hypothesized that the change in VLT handle increases at
a decreasing rate with respect to the number of slot machines. For this
reason, the number of slot machines was specified in quadratic form.
IV. MODEL ESTIMATION AND ANALYSIS
The system of three demand equations, (1)-(3), was estimated using
the SUR method (Zellner, 1962). The SUR method allows for possible
correlations among the errors of these equations and therefore improves
the estimation efficiency over that of estimating equation-by-equation
using the ordinary least squares method. The estimated equations are
given in Table 2.
The models fit the data well with [R.sup.2] greater than 0.78 in
each case. Twenty-one of the 33 seasonal variables were significant at
the 5% level or better. The coefficients of the linear component of own
number of VLTs were positive as expected, significant at the 7% level or
better in all three equations. The coefficients of the quadratic
component of own number of VLTs were negative as expected and
significant at the 5% level or better in all three equations.
The coefficients of the cross product (number of VLTs) variables in
each equation were negative and significant at the 5% level or better.
This shows substitutability among these products. The coefficients of
per capita personal income were positive in each equation, as expected,
significant at the 5% level or better in two equations and negative but
insignificant in the other. The coefficients of population were
positive, as expected, in all three equations and significant at the 5%
level or better in one. Finally, the coefficients of the smoking ban
variable were negative and significant at the 5% level or better in each
of the three equations.
The introduction of restrictions on smoking in public places in
Delaware, specifically at gaming facilities open to the public, was
found to have had a large impact on the demand for slot machine wagering
at the three Delaware racinos. Specifically, the impact of the smoking
ban was found to have resulted in reductions in slot machine handle of
15.7%, 17.8%, and 12.7%, respectively, at Delaware Park, Dover Downs,
and Harrington Raceway. (6) A standard chi-square test for equality of
reductions across the three racinos showed that the hypothesis of
equality cannot be rejected at any reasonable level of significance. (7)
Thus, the reductions in wagering, as expected, do not vary significantly
across the three racinos. The weighted average impact of the smoking ban
over the three racinos was computed to be 15.9%. (8)
V. SUMMARY AND CONCLUSIONS
The estimated equations of the demand for VLT wagering at the three
Delaware racinos fit the data well. The number of slot machines at a
racino facility and the market area income were found to be significant
demand determinants. The number of slot machines at competing in-state
racino facilities was also found to be a significant demand determinant.
Study results indicate that the Delaware racinos are substitutes for one
another.
A major focus of this study was on the impact of a smoking ban on
the demand for gaming. The introduction of restrictions on smoking in
public places in Delaware, specifically at gaming facilities open to the
public, was found to have had a large negative impact on the demand for
VLT wagering at the three Delaware racinos. Specifically, the impact of
the smoking ban was found to have reduced VLT handle for all three
racinos but the impacts were not found to vary significantly across
them. The weighted average reduction in VLT handle due to the smoking
ban was found to be 15.9%. To the extent that the smoking ban was not
fully enforced, its impact on VLT handle may have been underestimated.
The findings of a significant and negative impact of a smoking ban on
VLT handle (demand) are similar to the findings in Pakko (2005, 2006)
with respect to the impact on VLT revenue and are in contrast to the
insignificant negative impact on VLT revenue found in Mandel, Alamar,
and Glantz (2005b). They are also in contrast to earlier findings of an
insignificant impact of a smoking ban on taxable retail sales for
various other businesses such as restaurants, bars, and hotels.
Following Dunham and Marlow (2000a, 2000b, 2003, 2004), it is
expected that the effects of a smoking ban on businesses will decrease
over time as the smoking prevalence of the population continues to
decrease and customers are less likely to be affected by smoking ban
laws. To illustrate the historical trend in smoking ban incidence,
consider that the smoking prevalence of U.S. adults 18 years of age and
older decreased from 42.4% in 1965 to 20.9% in 2004 (U.S. Department of
Health and Human Services, Centers for Disease Control and Prevention,
2006). If this trend continues, it is likely that, with or without
smoking ban laws, the effects of smoking bans on business revenues and
profits will decrease in the long run. This speed of this potential
adjustment process was not a subject of this analysis.

SMOKEBAN
The fraction of a month over which the Delaware smoking ban was in
place. SMOKEBAN takes the value 0 prior to November 2002. The smoking
ban was in effect beginning November 27, 2002, and so SMOKEBAN was
assigned a value of 0.13 (4 d/30 d) for that month. For all months
subsequent to November 2002, SMOKEBAN takes the value 1.

(1.) The 13 states which permitted racino gaming in 2005 were
Alabama, Arkansas, Delaware, Florida, Iowa, Louisiana, Maine, New
Mexico, Oklahoma, New York, Pennsylvania, Rhode Island, and West
Virginia.
(2.) In this study, the terms VLTs and slot machines are used
interchangeably.
(3.) Data for the Charles Town racino slot machine win percent and
number of machines were available from the West Virginia Lottery. Data
for the Atlantic City casino slot machine win percent and number of
machines were available from the New Jersey Casino Control Commission.
(4.) Data were available from the Maryland, New Jersey, Virginia,
and West Virginia Racing Commissions, the Pennsylvania State Horse
Racing Commission, and the New York State Racing and Wagering Board.
(5.) Data were available from the Delaware, Maryland, New Jersey,
and Pennsylvania lotteries.
(6.) VLT handle impacts are computed using coefficients in
Equations (1)-(3) as follows: Delaware Park, [exp(0t17) - 1]100; Dover
Downs, [exp([[beta].sub.17]) - 1]100; Harrington, [exp(y17) - 1]100.
(7.) The Wald chi-square test with 2 degrees &freedom was 2.59
with p value of 0.2737.
(8.) The weighted average smoking ban impact is computed as each
individual racino's smoking ban impact weighted by that
racino's share of total Delaware 2004 VLT handle. Handle shares are
50.6%, 32.1%, and 17.3% for Delaware Park, Dover Downs, and Harrington
Raceway, respectively.
