this paper reflect only those impacts that remain within<br />

a given state. Storey and Allen (1993) accounted for the<br />

effects of imports on local supply in Massachusetts, however,<br />

the methods and assumptions used in constructing<br />

several components of the input-output model (e.g.,<br />

production functions and margins) varied considerably<br />

from those employed with the IMPLAN system. <strong>In</strong> addition,<br />

Storey and Allen (1993) used the standard type<br />

II multiplier to estimate the induced effects of angler<br />

expenditures. This procedure assumes that all household<br />

income is spent within the state of Massachusetts<br />

and that income and consumption are linearly related;<br />

that is, when income increases/decreases consumption<br />

increases/decreases proportionately. If household<br />

income is being spent outside the state or the marginal<br />

propensity to consume is not constant, then the type II<br />

multiplier will be overstated. <strong>The</strong> estimates shown in this<br />

study were based on IMPLAN’s type SAM multipliers<br />

which use information about inter-institutional transfers<br />

from IMPLAN’s social accounting matrix to account<br />

for leakage of household income out of the region,<br />

and a nonlinear consumption function that allows the<br />

marginal propensity to consume to decrease as income<br />

rises (see Minnesota IMPLAN Group, <strong>In</strong>c., 1997). <strong>The</strong><br />

differences between Kirkley and Kerstetter’s (1997) expenditure<br />

and impact estimates for Virginia and those<br />

shown in this report are not as easily explained. Different<br />

sampling procedures and expenditure categories<br />

may have contributed to the overall disparities between<br />

angler expense estimates, although the estimates are<br />

generally comparable for expense categories identified<br />

in both studies. Kirkley and Kerstetter’s (1997) impact<br />

estimates, however, are considerably higher than those<br />

generated in this study. <strong>The</strong> majority of the difference<br />

can be traced to discrepancies between the induced<br />

impact estimates. Kirkley and Kerstetter (1997) used the<br />

traditional type II multiplier to calculate impacts. Typically,<br />

the type II multiplier will result in higher induced<br />

values than IMPLAN’s type SAM multiplier. While these<br />

differences may explain some of the variation in the<br />

estimates, a systematic evaluation of both studies would<br />

be necessary to reveal all of the discrepancies between<br />

the two studies.<br />

<strong>In</strong> the SE, Bell, Sorensen, and Leeworthy (1982)<br />

estimated that saltwater recreational anglers spent $1.9<br />

billion in Florida in 1982, which equates to approximately<br />

$3.2 billion in 1999 dollars (according to the<br />

consumer price index). This is $5.1 billion lower than<br />

the estimate presented in Gentner, Price, and Steinback<br />

(2001a) for Florida in 1999 ($8.3 billion). <strong>In</strong> contrast,<br />

Bell, Sorensen, and Leeworthy (1982) predicted the<br />

total sales impact of anglers’ expenditures to be $8.8<br />

billion in 1999 dollars, approximately $4.2 billion<br />

higher than our estimate of sales derived from angler<br />

expenditures in Florida ($4.6 billion). <strong>The</strong>ir analysis<br />

did not include expenditures on durable goods, and<br />

the estimates of impacts were derived from various<br />

relationships between fishing expenditures and total<br />

expenditures in Florida. This rather atypical modeling<br />

approach is significantly different from the input-output<br />

approach presented here, so substantial differences in<br />

expenditure and impact estimates would be expected.<br />

<strong>The</strong> authors could find no other state or regional level<br />

analyses of saltwater recreational angling expenditures<br />

or impacts in the SE.<br />

For the PAC, McWilliams and Goldman (1994) estimated<br />

the economic impacts of both fresh and saltwater fishing<br />

in California in 1992. <strong>The</strong> authors used the IMPLAN<br />

Pro system and 1998 expenditure estimates provided by<br />

the ASA to generate impact estimates. <strong>Angler</strong>s’ expenditures<br />

on fresh and saltwater fishing combined were<br />

estimated to generate almost $5 billion dollars in sales/<br />

output impacts in California. Unfortunately, because<br />

freshwater and saltwater expenditures were aggregated<br />

in this study, it is not possible to compare estimates.<br />

Conclusion<br />

<strong>The</strong> impact estimates shown in this report may underestimate<br />

the state-level effects associated with marine<br />

recreational fishing. Because separate models were<br />

constructed for each state, the impacts measured only<br />

those effects that occurred within the state of interest.<br />

Impacts generated through the imports of goods and<br />

services from other neighboring coastal states were not<br />

part of each individual state assessment. For example,<br />

if a retail store in Rhode Island sold fishing tackle that<br />

was manufactured in Massachusetts, the impacts associated<br />

with the production of the fishing tackle were not<br />

part of the Rhode Island nor the Massachusetts impact<br />

assessment. <strong>The</strong> associated wholesale, distribution, and<br />

retail mark-ups that occurred in Rhode Island were<br />

included in the Rhode Island impact assessment, but<br />

the portion attributable to tackle manufacturing was<br />

not included in the Massachusetts assessment since the<br />

effects were generated from angler purchases in Rhode<br />

Island. As such, the impacts could have been higher<br />

than those shown in this report for states that exported<br />

fishing-related commodities to other neighboring<br />

coastal states. 15 <strong>The</strong>se impacts, however, are captured<br />

in the aggregate U.S. model.<br />

15 <strong>The</strong> interstate effects could have been determined by constructing<br />

an aggregate regional input-output model that included all<br />

coastal states within a region. This model would have been capable<br />

of tracking all of the associated trade and distribution channels<br />

that existed among the coastal states in the region. <strong>The</strong> IMPLAN<br />

system allows users to create aggregate models of this kind, but at<br />

the present time the software does not provide the ability to adequately<br />

isolate the impacts of the sub regions (i.e., coastal states)<br />

in aggregate models.<br />
