Bruce Lambert Moves to Institute for Trade and Transportation Studies
Bruce Lambert has left the Institute for Water Resources and the NETS team to begin work as the Executive Director of the Institute for Trade and Transportation Studies (ITTS). ITTS was formed by the Southeastern States to address predictions that increased international trade would change the nature of freight investment in the respective region. It continues to assist State departments of transportation to understand how changing freight patterns will influence regional transportation networks. Mr. Lambert will assist member states to develop public policy with regard to trade and freight transportation, prepare informational materials, monitor trade flows and research related to freight planning and logistics, and identify and provide training opportunities.

While with NETS, Mr. Lambert was prinicipal investigator for the Assessment and Development of Multimodal Analytical Models (Regional Routing Model), presented NETS Research at conferences and meetings in the U.S. and abroad, and led the effort to establish the Memorandum of Understanding between IWR and the U.S. Department of Agriculture's Economic Research Service.

HarborSym Deep Draft Field Review Group Scheduled for September
IWR and the Deep Draft Planning Center of Expertise plans to hold a field review group at IWR September 12-13, 2007. The field review group will assess the proposed HarborSym model enhancement of evaluating channel deepening alternatives (as well as channel widening alternatives). The group, including regional technical experts and senior economists with extensive experience in deep draft navigation, will make recommendations on how the deepening module should be implemented. The effort is led by Keith Hofseth and the HarborSym NETS team.

Wes Wilson Journeys to Europe
Professor Wesley Wilson made a presentation on NETS and discussed a study on Port Efficiency conducted by John Liu and Jia Yan at Hong Kong Polytechnic University at the Annual Meetings of the International Association of Maritime Economists (IAME.ORG) in Athens Greece July 4-6. In the Port Efficiency study, John Liu and Jia Yan use sophisticated econometric techniques to uncover the efficiency of container terminal operators. Their techniques allow the frontier production function of terminal operators and the relative efficiency of specific terminal operators to be identified. The research is currently underway, but will soon be available on http://www.icms.polyu.edu.hk/.

While in Europe, Professor Wilson also met with Anton Tchipev You are leaving a Federal Government web site.

Anton is studying issues related to transalpine freight transport and is exploring the possibility of adapting NETS research and tools.

Spatial Modeling in Transportation Accepted for Publication in the Journal of Regional Science
NETS Researchers Simon Anderson and Wesley Wilson, PhD, had a revision of "Spatial Modeling in Transportation II: Railroad Pricing, Alternative Markets, and Capacity Constraints" (pdf, 316KB) accepted for publication in the May 2008 Journal of Regional Science. The revised paper is titled "Spatial Competition, Pricing, and Market Power in Transportation: A Dominant Firm Model." In this paper, Anderson and Wilson examine railroad pricing over space and, in particular, the competition between rail and truck barge. They consider rail pricing in the context of waterway competition, capacity constraints, alternative markets, and the effects of backhaul markets.

“Popular” Version of Global Grain Report Published
NETS Researchers William W. Wilson, PhD, Eric A. DeVuyst, PhD, Richard D. Taylor, Bruce L. Dahl, and Won W. Koo, PhD, all at North Dakota State University, have published a “popular” version of the Global Grain Model. “Longer-Term Forecasting of Grain Flows and Delay Costs on the Mississippi River” was published in April 2007. The purpose of the study was to forecast grain and oilseed shipments through the Mississippi River system and to analyze impacts of delay costs.

The focus was on the world grain trade and expected changes in response to a multitude of evolving competitive pressures and structural changes. A spatial optimization model of the world grain trade, the study forecasted important parameters and used them to evaluate changes in flows through specific logistical channels. Projected import demands were based on consumption functions estimated using income and population and accounting for intercountry differences in consumption dependent on economic development. Each of the competing supply regions and countries were represented by yields, area potential that could be used in production of each grain, costs of production, and interior shipping costs, where relevant. Crucial in this model is the interior spatial competition between the U.S. Pacific Northwest and shipments through the U.S. Gulf, as well as inter-reach competition.
