This paper presents an approach to measuring the values of time cost for freight transportation, and examines its applicability through empirical analysis. We develop the method based on the hedonic approach by explicitly formulating how transport time is determined as market outcome. In the...

This paper presents a microeconomic model of interregional freight transportation based on careful formulation of cost structure in trucking firms and market equilibrium. It takes into account the feature of transport service as a bundle of multiple characteristics. We estimate the parameters of...
