Introduction Economics Letters 95 (2007) Charitable lotteries are a popular mechanism employed by fund-raisers to finance the provision of public goods. Morgan (2000) shows that lotteries obtain higher levels of public good provision than other voluntary mechanisms. A fundamental insight from this work is that lotteries can outperform voluntary mechanisms even when conventional explanations, such as risk loving behavior or consumption of Lead authorship is shared.

While recent experimental evidence provides support for the superior performance of charitable lotteries, it is difficult to infer the underlying motivations for giving in these settings (see e.g., Morgan and Sefton, 2000; Landry et al., 2006; Lange et al., 2007). This raises an interesting question: might individuals in these experiments be responding only to the wagering opportunity without any consideration for the attendant public good provision? In an attempt to understand the data patterns observed in these studies and discriminate between alternative motives for lottery play, we provide complementary evidence from naturally occurring data. Using state-level panel data from 1990 to 2000, we explore the effect of earmarking lottery proceeds on per capita lottery expenditures. Empirical estimates provide a number of insights suggestive of the importance of linking lottery purchases with the provision of a public good (education) and at odds with alternate explanations for lottery play. First, our results suggest per capita lottery expenditures are greater when proceeds are earmarked for education, suggesting individuals account for the link with public good provision. Second, we find that casino gambling is a substitute for state lotto in general fund states but has no effect on expenditures in Table 1 Summary statistics state lotto and casino gambling Per capita expenditures Earmark for education Multi-state lottery Casino gambling Arizona (6.75) No Connecticut (44.23) No Delaware (136.82) No Indiana (11.46) No Iowa (5.49) No Kentucky (32.64) No No Louisiana (16.18) No Maine (18.06) No No Maryland (23.92) No No No South Dakota (44.9) No Yes No West Virginia (37.36) No No California (10.05) No Florida (9.34) Yes No Yes Georgia (35.18) Yes No Yes Idaho (10.41) Yes No No Illinois (5.22) Yes Yes No Michigan (18.85) Yes No New Hampshire (29.63) Yes No New York (39.54) Yes No No Ohio (25.06) Yes No No Missouri (19.56) Yes Montana (110.58) Yes No Oregon (156.26) No Texas (24.79) No No Vermont (23.43) No No Virginia (18.24) No No Note: Cell entries provide data on the average per capita lottery expenditures and other factors that may influence lottery purchases.

The final column reports the percentage change in average expenditures generated by the switch. Standard errors are in parentheses. Cell entries can be read as follows: average per capita lotto expenditures in Missouri when proceeds were designated to the state's general fund (education) were $40.34 ($69.98). states that earmark. If bettors purchase lottery tickets solely for a love of gambling, we would expect casino gaming to crowd out expenditures in both general fund and earmark states. Finally, we find that per capita lottery expenditures are increasing in percentage of proceeds allocated to the public account. If the primary motivation for state lotto play was a love of gambling, variation in allocations to the public account should have no effect on expenditures. 2. Data and empirical results During the period , we observe twelve states in the U.S. that allocated lottery proceeds to the state's general fund, nine states that earmarked funds for education and six states that switched the allocation of proceeds between these categories. To test the importance of the link between lottery purchases and public good provision, we compare annual per capita lottery expenditures when proceeds are earmarked for education versus the state's general fund. Table 1 provides a state-level summary of our data. Average per capita lottery expenditures in states that designate lottery proceeds for education (the state's general fund) are $ ($116.99) respectively, with this $15.52 difference statistically significant at the p b 0.05 level. Table 2 delineates average per capita expenditures by allocation in the six states that switch the designation of lotto proceeds. One clear data pattern noted in the table is a ubiquitous increase in annual expenditures when a state allocates lotto proceeds to education. To complement these unconditional insights, we estimate a series of linear regression models that explicitly control for observable and unobservable differences across states. Specifically, we estimate a linear regression model of the natural log of per capita lottery expenditures as: exp jt ¼ Z jt b þ a j þ e jt where exp jt is natural log of per capita lottery expenditures for state j in year t, Z is a vector of characteristics including a dichotomous indicator for earmarking of lottery proceeds for education, and the α j 's are state fixed effects. To account for unobservable temporal heterogeneities, standard errors are clustered by year. Empirical estimates presented in Column 1 of Table 3 provide results consistent with the unconditional insights: per capita lottery expenditures are approximately 60% higher in states that earmark lottery proceeds ð1þ

Combined, these results suggest the importance of linking lottery purchases with public good provision. If the sole motivation for state lottery play was the wagering opportunity, per capita expenditures should be independent of the designation and magnitude of proceeds allocated to state budgets. Our data set is sufficiently rich to determine whether lotto play is motivated by a love of gambling by measuring the impact of casino gaming (a substitute form of gambling) on lotto purchases. Model B in Table 3 provides evidence that casino gaming is a substitute for state lotto play. The presence of legalized casino gambling generates an approximate 9.4% reduction in per capita lotto expenditures with this difference significant at the p b 0.05 level. However, this substitution is incomplete: it only offsets a portion of the approximate 55% expected gain associated with earmarking. Empirical estimates in Model C highlight that this crowding result is robust to alternate specifications that include state demographics such as per capita income and population. Exploring this result a level deeper, Models D and E highlight an important asymmetry in the impacts of casino gaming. In general fund states, the presence of legal casinos is associated with an approximate 17% reduction in annual per capita lotto expenditures with this difference significant at the p b 0.05 level. For states that earmark, the introduction of casino gaming generates a reduction in per capita lottery expenditures of only 3%. However, this reduction is not significant at any meaningful level. If state lotto purchases are driven by a love of gambling, casino gaming should crowd out expenditures in both general fund and earmark states equally. Hence, our results are at odds with such alternate theories. 3. Conclusions This study provides empirical evidence from state lotto play that allows us to discriminate between alternate theories for lottery purchases. Empirical results suggest per capita lotto expenditures are greater when proceeds are earmarked for education. Further, we find that casino gambling is a substitute for state 1 We calculate the marginal effects for indicator variables by 100{exp(β) 1} as suggested in Halvorsen and Palmquist (1980).

Combined, these results suggest wagering individuals respond to attendant public good provision when purchasing state lotto tickets.
