Estimating economic information for fisheries using unequal probability sampling

This study provides detailed descriptions of procedures for conducting unequal probability sampling (UPS) and deriving the population parameters for important economic variables that are critical in economic analysis of fisheries. This study uses a Pareto sampling method and describes how the Horvitz-Thompson (HT) estimator is adjusted for non-response and how this adjustment is applied to the certainty units and non-certainty units separately. As an example, this study applies the UPS method without replacement to fisheries in the Southwest region of Alaska, to estimate the total employment and total labor income for each of three disaggregated harvesting sectors. This study shows that the suggested method is a useful approach that can be used to estimate similar economic information through surveys of fish harvesting and processing sectors.
