JRAP (2000)30:1 A Simple Procedure for Generating Confidence Intervals in Tourist Spending Profiles and Resulting Economic Impacts

By Donald B. K. English


Abstract. This paper presents a simple bootstrap procedure to develop multivariate confidence intervals for tourist expenditure profiles and consequent estimates of economic impacts per thousand tourist visits. Mean expenditures from replicated visitor expenditure data included weights to correct for response bias. A covariance matrix for means of 50 expenditure items is estimated through 2,000 bootstrap replications for two separate visitation seasons. Confidence intervals assume multivariate normality of the expenditure means, and focus on endpoints defined by proportionate increases (and decreases) from the original sample data means. An empirical example is provided from summer and winter visitors to the Florida Keys. Ninetyfive percent confidence interval endpoints for spending means were found at 3.87 percent above/below the original sample's point estimate for winter visitors and at 6.001 percent for summer visitors. 1
