Experimental Design
The study uses two linked experimental components to evaluate the performance of the new RMS2 customs risk management system and its effect on assessment officers’ decisions. First, to create reliable “ground-truth” outcomes for comparing RMS2 with the existing FBR Risk Management System (RMS1), a randomly selected subset of Goods Declarations (GDs) is assigned to a forced-Red channel. All GDs are initially risk-scored and classified by RMS1 as Red, Yellow, or Green. Within each classification and risk score range, GDs are randomly selected for mandatory full documentary review and physical inspection, regardless of their original channel. This forced-Red process generates verified inspection results that enable a direct ex-post comparison of how accurately RMS2 and RMS1 identify high-risk filings, while all other GDs proceed under standard business-as-usual procedures.
Second, to measure the effect of providing officers with additional risk information, assessment officers are randomly assigned to either a control group or a treatment group. Control officers follow existing procedures without access to the RMS2’s interface and channel assignments, while treated officers receive full access to RMS2’s channel assignments and detailed features such as is there a predicted hs code discrepancy, is there an origin country discrepancy, and is there a valuation discrepancy, and if so, then how much. Outcomes are compared across forced-Red and business-as-usual cases, allowing the study to isolate improvements in risk targeting, the informational effect of RMS2 on officer decision-making, and the overall operational impact of integrating RMS2 into customs processes.
