... is differentiating between products that originate from legal sources from the minority of products originating from illegal ones.1 A number of methods have been used to grapple with these difficulties and produce estimates of the global size of the illicit tobacco market, as well as estimates for specific countries. The first section of this chapter describes and assesses seven different methods and provides estimates derived from each.
From page 78...
... Residual methods -- such as trade gap analyses, comparisons of self-reported consumption and tax-paid sales, and econometric modeling -- combine two or more sources of data on the illicit and licit markets to infer the scale of the illicit market. Direct measurement estimates, quantifying a particular segment of the illicit market, are based on such methods as empty pack collections and pack observation, return, and swap surveys, which are typically conducted in neighborhoods or cities.
From page 79...
... Comparing Tax-Paid Sales and Self-Reported Consumption Measures Levels of tax avoidance and tax evasion can be found by comparing the reported sales on which taxes were paid and self-reported cigarette consumption based on population surveys. Of course, there are many reasons why tax-paid sales and self-reported consumption may differ, such as underreporting of smoking prevalence and consumption by smokers, failure to include certain segments of the population in surveys (e.g., institutionalized populations, military)
From page 80...
... Econometric modeling has been used extensively to estimate the scale of the illicit tobacco market in the United States (see Becker et al., 1994; Yurekli and Zhang, 2000; Farrelly et al., 2003)

... , can be used to determine the prevalence of cross-border shopping, direct purchasing, and duty-free purchasing. Because there are few laws against purchasing illicit tobacco products, tobacco purchasers have little or no legal incentive to conceal their behavior.

... surveyed discarded cigarette packs in New Zealand; Merriman (2010) used this method in Chicago, collecting littered packs in order to estimate the levels of tax evasion and tax avoidance of Cook County's and the city of Chicago's tobacco taxes; and Kurti and colleagues (2012)
From page 84...
... Empty pack surveys have also been used by the tobacco industry to estimate the size of the illicit tobacco market. However, researchers have questioned their findings and methodologies.
From page 85...
... If similar surveys are conducted over time, the relative scale of the illicit tobacco market may also be gauged. Pack return and pack swap surveys have been conducted in Europe and the United States.
From page 86...
... Expert Opinion A number of published estimates of the size and growth of the illicit tobacco market are based on surveying experts -- customs and law enforcement officials, industry representatives, researchers, tobacco control professionals, and other informed parties. Estimates based on this method often appear in trade and government publications (Merriman, 2001)
From page 87...
... Tobacco control advocates may have an interest in underestimating the extent of the illicit tobacco market in order to support their efforts to enact higher tobacco taxes. Law enforcement officials may have an interest in reporting higher levels of illicit trade in order to procure continued funding for enforcement efforts, or they may report lower levels of illicit trade in order to argue that their enforcement efforts have been effective (International Agency for Research on Cancer, 2011)
From page 88...
... . The failure to use publicly available and accepted data sources is noteworthy and highlights the importance of transparent and independent approaches to conducting research on the illicit tobacco market.
From page 89...
... These methods differ in sample sizes, time periods covered, and scientific rigor, and they yield different estimates and have different sources of error. In light of these factors, it is important to consider estimates from multiple methods in order to obtain the most comprehensive picture of the scale of the illicit tobacco market for a specific location and time.

... Methods, Data, and Measures Methods To develop its own estimate of the size of the illicit tobacco market in the United States, the committee used a residual method, specifically, comparing tax-paid sales and self-reported consumption measures. The committee chose to use this method for four reasons: (1)

... and ran­ dom large seizures. The RCMP seizure data do seem to reflect, to some extent, the market forces in the illicit tobacco industry for the period under study.
From page 95...
... The committee then estimated cigarette tax evasion and avoidance by summing both statelevel deficits and surpluses between sales and self-reported consumption.
From page 96...
... . The committee then multiplied this annualized estimate of cigarette consumption by the estimated state-level smoker population to create a measure of total self-reported consumption of packs of cigarettes for each state (i.e., [annual self-reported consumption]

... , the net importing states lost an estimated $2.95 billion in excise taxes and roughly $2 billion in sales taxes, while net exporting states gained an estimated $0.82 billion in excise taxes. These figures can be compared with total tobacco tax revenue collections, which were $17.65 billion at the state and local levels in 2011 (Tax Policy Center, 2013)
From page 98...
... Table 4-4 shows the estimated state excise taxes gained and lost for 2010-2011 for the top five net exporting and importing states. The committee estimates that the state of New York loses the most revenue due to illicit tobacco purchases, nearly half of all revenue lost nationwide.

... rate with the U.S. Income Tax Code.6 At the state level, roughly 18 percent of taxes go unpaid, constituting a loss of roughly $136 billion.7 As another comparison, the Insurance Research Council estimated that in 2007, auto insurance companies paid between $4.3 and $5.8 billion dollars in fraudulent claims, between 11 and 15 percent of the dollar value of all claims.8 6 Once criminal prosecutions and late payments are taken into account, the total amount of tax revenue lost each year, primarily due to underreporting of business income, is $385 billion a year, or about 14.5 percent.

From page 104...
... New York State accounted for nearly half of the total revenues lost. Overall, the total amount of tax revenue lost to the illicit tobacco mar ket is roughly 10 percent of the total tobacco tax due, which is smaller than estimates of the "income tax gap" of 17 percent at the federal level and 18 percent at the state level.

... The committee's estimate of the size of the illicit tobacco market in the United States also differs from other recent studies, and there are a number of possible explanations for these differences. First, the committee's estimates are likely lower because they reflect net transfers of cigarette packs between states.

... illicit tobacco market is slightly larger as a share of the total market than the illicit market in Canada, which the committee estimates to be between 7.6 and 14.7 percent of the total market. RECOMMENDATION 4-1  The Tobacco Use Supplement to the Cur rent Population Survey should be expanded in both the number of questions and specificity of questions currently asked regarding tobacco use and illicit tobacco market participation.
From page 109...
... More ac curate estimates of the size of the illicit market separately attributable to tax avoidance and tax evasion could be obtained by combining more systematic data collection on discarded packs in states with significant illicit trade with (1) an expansion in the number and specificity of ques tions currently asked in representative population surveys regarding to bacco use and illicit tobacco market participation and (2)
