The projected impact of inland waterway user charges on grain flows and transport costs in 1990

“…The structure of this constraint is similar to the export rail-car day constraint defined above. The interested reader is referred to Hauser [21] for a more complete discussion. The quantity of grain received at export port e via mode m in time period t cannot exceed the port unloading capacity for that mode.…”

“…^ The Sink ley study is the only analysis, independent of the one examined in this dissertation, to employ a national model. In companion studies to this analysis, Hauser [21] and Data Resources Incorporated [17] investigate the impacts of user charges at the national level. the elimination of capacity constraints from the analysis thus ensured that user charges rather than capacity limits could serve as binding constraints.…”
