Tradable Permits for Inland Waterways Final Report
NETS researchers Dr. Charles Plott and Dr. Joseph Cook of National Economic Research Associates have submitted a final report on tradable permits for locks on inland waterways. The researchers explored mechanisms for the inland waterway system that would allow individuals to reduce their overall transportation cost, reduce uncertainty associated with potential delays and place a dollar value on the benefits of reducing the duration of or eliminating critical delays.

New Measures of Port Efficiency
In a recently-released draft paper, researchers Drs. Bruce Blonigen and Wesley Wilson of the University of Oregon, provide a new statistical method of understanding port efficiency measures using U.S. Census data on imports into U.S. ports. The study estimates a broader sample of countries and years and can be used to examine issues such as the evolution of port efficiencies over time and its effects on international trade flows and country-level growth.

NETS Researchers Present HSAM Animation Module at HMS2005
NETS researchers Keith Hofseth of IWR and Cory Rogers of CDM presented HSAM: An Interactive, Immersive Animation of Deep-Draft Maritime Traffic Simulations at HMS2005, the conference for Harbour, Maritime & Multimodal Logistics Modelling and Simulation, October 20-22.

HSAM is the HarborSym Animation Module, an interactive, immersive visualization of deep draft maritime traffic simulations developed by the U.S. Army Corps of Engineers. The program interfaces with HarborSym databases and provides a flexible and cost-effective solution for planning level analyses.

Overview of the U.S. Inland Waterway System
In a new paper, students in the Department of Economics at the University of Oregon, under the supervision of Dr. Wesley Wilson, present an overview of the U.S. waterway system that includes a detailed look at the Mississippi, the Ohio River Basin, the Gulf Intercoastal Waterway, and the Pacific Coast systems. Growth patterns are explored and commodities transported are analyzed and identified, with the data indicating that the primary commodity transported by the system as a whole is petroleum and petroleum products. The overview was authored by Chris Clark, Kevin Henrickson, and Paul Thoma.

Demand for Ohio River Shipments
Students at the University of Oregon and the University of Tennessee, under the supervision of Dr. Wesley Wilson, studied the behavior of shippers and their demand for waterway transportation on the Ohio River Waterway System. The study used survey data from a sample of 179 shippers, who provided information on how their quantities would respond to changes in transportation rates and transit times, to estimate a TOBIT model of annual shipments and commodities. The draft paper was authored by Nino Sitchinava, Mark Burton, and Wesley Wilson.
