The valuation of shipment time variability in Greater Mekong Subregion

The value of shipment time variability is estimated using the stated preference data from shippers engaging in cross-border transport in Greater Mekong Subregion. Respondents are asked to choose between two alternatives which differ in terms of shipment time, cost, shipment time variability and departure time. In the study route, two bottlenecks (border and seaport) violate stability of shipment time. These two shipment time distributions are convoluted by Monte Carlo method. The results show that the value of schedule delay late is 5.6 times larger than normal travel time savings.
