1. Katrina and the Gulf States Casino Industry
Douglas M. Walker (College of Charleston)
and John D. Jackson (Auburn University)
Paper presented at the 2007 Southern Economic Association Conference, November 19-21, 2007, New Orleans, LA.

2. Background Katrina hit along the LA-MS border in Aug. 2005.
Rita hit near the LA-TX border in Sept
The casino industry in LA and MS was devastated, since much of the industry was located in hurricane affected areas.
Our analysis is of the relationship between the casino industry and state-level personal income, and how this relationship was affected by Hurricanes Katrina and Rita.

4. The casino industry in LA and MS
LA and MS are relatively isolated markets for commercial casinos
They attract tourism
Isolation
Situated on state borders/rivers, or in tourist cities
Casinos may drive state-level economic growth
Walker and Jackson (1998) found a significant short-run effect using data, for all U.S. states with commercial casinos
But our 2007 paper found no significant long-term effect, using data
Econometric studies of the effects of casino gambling are still rare

9. Our question
The previous tables and charts indicate the how quickly the casino industry rebuilt.
Would such a strong recovery in this industry have an impact on the states’ post-Katrina (and Rita) economies?

10. The data
We use real quarterly LA and MS personal income and casino revenue data.
Quarterly data are used rather than annual, in order to maximize the number of observations.
Post-Katrina annual data are limited
Our casino revenue data exclude non-casino video poker and slot machines.
Indian casinos are excluded because data are not publicly available.

11. Data, cont.
We use personal income rather than per capita income to measure economic growth.
Before and after Katrina there was significant migration from New Orleans and the Biloxi/Gulfport area.
Migration may not be accurately reflected in per capita income data.
Personal income data are available quarterly; state-level per capita GDP data are not.

12. Data, cont. Data set begins in 1997.1
We want to avoid picking up the initial stimulus effect we found in our 1998 paper.
The Louisiana Gaming Control Board was created in 1996; previously the State Police reported data. Beginning in 1997 allows us to use data from only one agency.
Aside from these reasons, beginning in 1997 is a nice balance to the post-Katrina data available.

13. Data, cont.
The data end in , the last period for which personal income data were available (as of the paper writing).
39 quarters of data on each variable for each state, for 78 total observations.
Katrina and Rita were both in
34 observations in each state are pre-hurricane ( )
5 post-hurricane observations ( )

14. The model
Personal income (t0) = b1 Constant + b2 Personal income (t-4) + b3 Casino revenue (t0) + b4 Casino revenue (t-4) + b5 Katrina dummy + b6 Katrina * (Casino revenue) + b7 State dummy + e (t0)
Personal income one year prior is an explanatory variable since annual personal income is a random walk.
A four period lag for casino revenues was chosen after an analysis of the correlogram.
Current values for casino revenue appear not to be affected by immediate past quarters’.
The fourth lagged period of casino revenue significantly affects current period’s.
Probably an annual cycle.
State dummy is included (1 for MS, 0 for LA)
Katrina dummy (1 from periods through ; 0 otherwise) includes effect from Rita

15. Model, cont.
Katrina – revenue interaction term will pick up relationship between casino gambling and personal income above and beyond that explained by revenue t0 and t-4
This should tell us how the effect of casino revenues on income enhances (b6>0) or detracts (b6<0) from economic recovery.
Omitted variables include…
Seasonal dummies: insignificant, and didn’t affect other coefficients
Time trend: insignificant and didn’t affect other coefficients
FEMA relief, other federal or state relief, and insurance settlements were not explicitly accounted for in the model
BEA indicates that these are accounted for in the personal income data

17. Conclusions
Clearly, the hurricanes devastated personal income in LA and MS
The hurricane dummy is strongly negative
The interaction term is positive, indicating that increases in casino revenues have a significantly greater expansionary effect on personal income after the hurricanes than before them.
This result is consistent with our earlier findings (1998) of at least a short-term growth effect from casino gambling.
Capital investment, labor flows, etc., may explain this.
