Spanish shipping firms relied on va

Spanish shipping firms relied on various strategies to direct the growth of their industry from 1860 to 1930. The diffusion of specialist shipowners during the second half of the nineteenth century was the result of both an increasing demand for maritime transport and a heavy rise in capital requirements owing to improvements in technology. During the first third of the twentieth century, some of these specialized firms became large companies through internal growth and/or horizontal combination. They achieved their gains without resorting to formal vertical integration, choosing instead to build social networks with other shipowners based on trust and loyalty. This approach allowed them to create intermediate arrangements, thereby diminishing transaction costs. When strategies of formal vertical integration were adopted, they primarily involved activities similar to shipping, such as ship brokering, consignment, stevedoring, and other maritime services. To document these trends, this article analysis the organizational structure of Spain's twenty largest shipping concerns.
