TRADE MISINVOICING, CUSTOMS ENFORCEMENT, AND CAPITAL FLIGHT: AN EMPIRICAL LAW-AND-ECONOMICS ANALYSIS OF REVENUE LEAKAGE IN EMERGING ECONOMIES

Abstract

Trade mis invoicing constitutes a major source of customs revenue loss and illicit financial flows, yet it remains inadequately theorized within both customs law and international economics. Existing scholarship predominantly treats mis invoicing as a compliance of failure arising from weak enforcement, regulatory gaps, or opportunistic evasion. This article challenges that conventional account by reconceptualizing trade mis invoicing as a rational response to the incentive structures embedded within customs valuation regimes, tariff differentials, and administrative discretion. Drawing upon a law-and-economics framework, it examines the way legal institutions shape economic behaviour and create opportunities for regulatory arbitrage in cross-border trade. The study employs a multi-jurisdictional panel dataset constructed from mirror trade statistics and institutional governance indicators to estimate the magnitude and directional asymmetries of trade mis invoicing. Through econometric analysis, it evaluates the effects of enforcement intensity, tariff dispersion, and administrative discretion on mis invoicing outcomes. The analytical framework integrates institutional economics, transaction-cost theory, and efficiency-oriented legal analysis to assess the behavioural and allocative consequences of customs regulation. The findings indicate a non-linear relationship between enforcement stringency and compliance. In institutional environments characterized by opacity and broad discretionary authority, stricter enforcement is associated with the emergence of adaptive evasion strategies, including more sophisticated forms of mis invoicing and the redirection of illicit financial flows. These results suggest that persistent mis invoicing may reflect not only deficiencies in enforcement capacity but also distortions generated by the design of the regulatory framework itself. The article contributes to the literature by developing an integrated theoretical account of customs enforcement as an economic institution, providing empirical evidence on the conditional effectiveness of enforcement mechanisms, and advancing a normative framework for customs reform cantered on transparency, rule-based governance, and reduced administrative discretion. By shifting attention from enforcement alone to institutional design, the study offers a more comprehensive explanation of trade mis invoicing and its persistence in developing economies.
