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...

"The welfare effects of trade shocks depend crucially on the nature and magnitude of the costs workers face in moving between sectors. The existing trade literature does not directly address this, assuming perfect mobility or complete immobility, or adopting reduced-form approaches to...

Trade data are typically reported at the level of regions or countries and are therefore aggregates across space. In this paper, we investigate the sensitivity of standard gravity estimation to spatial aggregation. We build a model in which initially symmetric micro regions are combined to form...
