Trade  changes  incentives  to  protect  an  open-access  natural  re-source independently of its effect on the resource price.  A new paper published in the Dynamic Games and Applications studies how general equilibrium linkages cause resource policy to affect the price of privately owned assets regardless of whether they are used in the resource sec-tor.  In the closed economy, the asset market in our overlapping generations setting creates incentives for currently living agents to protect the natural resource.  The interplay of the asset market and general equilibrium effects cause trade to reverse these incentives.  Trade liberalization and the establishment of formal property rights are policy complements:  the former makes the latter more important.
