We empirically analyze the illicit trade in cultural property and antiques, taking advantage of different reporting incentives between source and destination countries. We thus generate a measure of illicit trafficking in these goods based on the difference between imports recorded in United States' customs data and the (purportedly identical) trade as recorded by customs authorities in exporting countries. We find that this reporting gap is highly correlated with the corruption level of the exporting country as measured by commonly used survey-based indicies, and that this correlation is stronger for artifact-rich countries. As a placebo test, we do not observe any such pattern for U.S. imports of toys from these same exporters. We report similar results for four other Western country markets. Our analysis provides a useful framework for studying trade in illicit goods. Further, our results provide empirical confirmation that survey-based corruption indicies are informative, as they are correlated with an objective measure of illicit activity.
Despite every best effort, many museums have made acquisition mistakes in the past and unwittingly accessioned works of art that were stolen from storerooms or plundered from archaeological sites. No museum should deaccession an object without having a justifiable reason for doing so. If, however, an investigation turns up looted antiquities in a museum collection (for example, if photographs show an object shortly after it was illicitly removed from the ground, or if its provenance documentation was demonstrably forged), then a museum has an obligation to redress the break in the chain of that object’s ownership in some way. Usually such a resolution is achieved through a financial settlement with, or physical return to, the country of modern discovery. Museums hold their collections as public trusts, and no museum should wish knowingly to retain stolen property on behalf of the public.
3. Ferromagnetic detectors are becoming a favorite in the contraband smuggling and detection field. The cell phone does not need to be turned on for the detection to happen. The detector picks up the electromagnetic field generated by any mobile phone – even OFF and with the battery removed. The downside is the range is short and sometimes less than a foot.
In August 2004, experts examined the works and found inconsistencies. Greene, who had shipped the works from his home in San Francisco, had also been unable to provide provenance and import and export documentation. The collection committee proceeded to veto the annuity deal made months prior. That same year, the de Young museum pulled out of a deal with Greene, this time in exchange for Philippine tribal art, for similar reasons.

So long as museums continue to spend money to acquire even well-provenanced antiquities, they will be signaling that antiquities are worth a lot of money whether well-provenanced or not. That in turn will drive continued circulation of recently-looted artifacts for less-fastidious collectors around the world. Museums should certainly make provenance info about objects acquired from dealers who have been arrested, they need to do much more than that if they want to make a real difference. To begin with, all provenance information about all artifacts that museums consider acquiring — not just about artifacts sold by arrested dealers, not just about artifacts acquired, but also artifacts looked at and refused because the provenance looked dodgy — should be made available for researchers and to the police. Beyond that, museums should shift themselves, and encourage collectors to shift, away from purchasing antiquities so as to reduce demand, and museums should think of ways in which they might generate financial support to help pay for more site guards. One way would be for museums to take out of storerooms and lease out artifacts that collectors would gladly pay to temporarily display (like the Palmyra sculpture the Boston MFA showed for the first time in decades to honor the decapitated Palmyra site director). Another way would be for museums to push collectors and dealers to join them to support the imposition of a tax on antiquities sales, with the revenues dedicated to funding better and more site protection and policing of the illicit trade.
Buried treasure, mysterious deaths, looting, forged documents, secretive Swiss bank vaults and shadowy intermediaries. This is not a description of a Dan Brown thriller. It’s real life: the trade in illegally exported antiquities. As prices soar into the millions of dollars for the top pieces, so does the incentive to dig up treasures in Italy, Greece, Turkey and farther afield, pass them to “runners” who will sneak them illegally across borders, store them in a Swiss vault and then quietly slip them into the trade. The players in this murky world can make a fortune, but this is a dangerous game.
