The exporters are credit constrained for working capital, incur the per-shipment fixed costs, and get paid after goods delivered to the importer. The model shows that for high financing costs in origin and destination, the shipping frequency increases. Furthermore, longer delivery times increase shipping frequency as well as procurement costs. The model also shows that the higher per-shipment fixed costs reduce the shipping frequency, in l...
