Erica Chuang, Ph.D. candidate in the University of California San Diego Department of Economics, presented on principle of targeting for environmental externalities. Economists generally agree that in terms of tax and subsidy structure, Pigou is king. However, market-based instruments that imprecisely target externalities are common, and the degree to which imprecision matters for the objectives of those policies has yet to be fully explored.

TJ Anderson discussed ongoing work evaluating the effectiveness of disease management practices in the Chilean salmon aquaculture industry.  In Chile, Atlantic Salmon are raised in large floating cages called net pens located in near-shore waterways. The net pens hold salmon while they are raised, allowing for the free flow of sea water in and out of the cage.

Xiurou Wu updated her research on addressing ecosystem service trade-offs in China's Lake Poyang. This research proposes a model of ecosystem service management that takes into account the conflict between fisheries operations and conservation of endangered and threatened waterfowl, specifically Siberian Cranes. The model is calibrated to fit the example of China’s largest freshwater lake, Lake Poyang, the wintering ground for the last surviving population of Siberian Cranes.

Xiurou Wu and Pierce Donovan presented their research on "modeling ecosystem service conflicts in China’s Lake Poyang" and "encouraging habitat defragmentation across a privately-owned landscape" at BIOECON XXII.
