    This paper examines how providing better information to customs inspectors and monitoring their actions affects tax revenue and fraud detection in Madagascar. First, an instrumental variables strategy is used to show that transaction-specific, third-party valuation advice on a subset of high-risk import declarations increases fraud findings by 21.7 percentage points and tax collection by 5.2 percentage points. Second, a randomized control trial is conducted in which a subset of high-risk declarations is selected to receive detailed risk comments and another subset is explicitly tagged for ex-post monitoring. For declarations not subject to third-party valuation advice, detailed comments increase reporting of fraud by 3.1 percentage points and improve tax yield by 1 percentage point. However, valuation advice and detailed comments have a significantly smaller impact on revenue when potential tax losses and opportunities for graft are large. Monitoring induces inspectors to scan more shipments but does not result in the detection of more fraud or the collection of additional revenue. Better information thus helps curb customs fraud, but its effectiveness appears compromised by corruption.

    To identify transactions at risk of tariff evasion, this paper matches export transaction data from France with import transaction data from Madagascar using container identifiers. Reporting discrepancies between exporters and importers are prevalent but small, with over two-fifths of importers reporting in a way that increases their tariff liability. Yet, aggregate tariff revenues are 24 percent lower due to discrepancies. These revenue losses are highly concentrated: the top five evaders account for three-quarters of all tariff revenue losses and larger shipments are more at risk of evasion. Tariff enforcement in Madagascar is ineffective and only marginally mitigates revenue losses.

    Based on a natural experiment that took place in Ecuador in the context of a capital outflow tax, this paper presents suggestive evidence of the emergence of an abnormal transfer pricing behavior. We exploit the fact that some imports were eligible to a tax-credit measure aiming to offset the capital outflow tax. The identification strategy relies on the fact that a foreign multinational enterprise has only an incentive to increase the unit value -transfer price- for profit shifting motivations of products eligible to the tax-credit. Then, comparing the evolution of the unit value of eligible products (the treatment group) with that of non eligible products (the comparison group) before and after the tax-credit measure, we estimate the over-reporting incentive's impact on the reported value. Results show that the declared unit value of eligible imports increased following the introduction of the tax-credit measure. Various tests suggest that this abnormal increase is attributable to a profit-shifting behavior.

    This paper presents a new methodology to detect corruption in customs and applies it to Madagascar’s main port. Manipulation of assignment of import declarations to inspectors is identified by measuring deviations from random assignment prescribed by official rules. Deviant declarations are more at risk of tax evasion, yet less likely to be deemed fraudulent by inspectors, who also clear them faster. An intervention in which inspector assignment was delegated to a third party validates the approach, but also triggered a novel manifestation of manipulation that rejuvenated systemic corruption. Tax revenue losses associated with the corruption scheme are approximately 3 percent of total taxes collected and highly concentrated among a select few inspectors and brokers.

    This paper examines how providing better information to customs inspectors and monitoring their actions affects tax revenue and fraud detection in Madagascar. First, an instrumental variables strategy is used to show that transaction-specific, third-party valuation advice on a subset of high-risk import declarations increases fraud findings by 21.7 percentage points and tax collection by 5.2 percentage points. Second, a randomized control trial is conducted in which a subset of high-risk declarations is selected to receive detailed risk comments and another subset is explicitly tagged for ex-post monitoring. For declarations not subject to third-party valuation advice, detailed comments increase reporting of fraud by 3.1 percentage points and improve tax yield by 1 percentage point. However, valuation advice and detailed comments have a significantly smaller impact on revenue when potential tax losses and opportunities for graft are large. Monitoring induces inspectors to scan more shipments but does not result in the detection of more fraud or the collection of additional revenue. Better information thus helps curb customs fraud, but its effectiveness appears compromised by corruption
