Imposing trade restrictions on parallel imports can motivate a firm to export, study finds

Imposing trade restrictions on parallel imports has the surprising effect of motivating a firm to export, according to a new study using game theory economic analysis, says co-author Santanu Roy, SMU. The study found that diverse parallel importing policies make it possible to analyze for the first time how competition between firms and allowing or banning parallel imports can influence competition.

New analysis weighs lost trade, costs to control invasive species against economic damages

Zmussels%20in%20Maryland%20coastal%20bays1.jpgBiological alien invaders often travel via international trade, prompting trade regulations to stop them. Pesky invaders like Zebra mussels, Asian Longhorned Beetles, Kudzu, Triffid weed and others have wreaked billions of dollars in economic damage, destroying agriculture, harming human health and threatening biodiversity.

Policymakers must balance concerns about the damage and cost of controlling invaders against the economic necessity of free trade, say economists Santanu Roy, Southern Methodist University, and Lars J. Olson, University of Maryland.

In their research, Roy and Olson examine the various conditions policymakers must evaluate to determine the best policies governing invasive species based on sound economics.

With a population estimated at 1,500, the wolf re-established itself in the Yellowstone National Park area, and in March 2008 the U.S. Fish and Wildlife Service removed it from protection under the Endangered Species Act.

Almost immediately, hunters began petitioning the state offices of Idaho, Montana and Wyoming for permits to hunt the wolves, perhaps down to as little as 20 percent of their current numbers in some areas. Such a weighty issue begs the questions: How much hunting is safe for a given species? How many gray wolves can die before the species loses its chance at recovery?
